  • BOXED WARNING(What is this?)

    WARNING

    INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS
    Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. Olanzapine is not approved for the treatment of patients with dementia-related psychosis. [See Warnings and Precautions (5.1,5.14) and Patient Counseling Information (17.2)]. When using olanzapine and fluoxetine in combination, also refer to the Boxed Warning of the package insert for olanzapine and fluoxetine in combination.

  • INDICATIONS & USAGE

    1.1 Schizophrenia
    Olanzapine Tablets USP are indicated for the treatment of schizophrenia. Efficacy was established in three clinical trials in adult patients with schizophrenia: two 6-week trials and one maintenance trial [see Clinical Studies ( 14.1)].
    When deciding among the alternative treatments for adolescents, clinicians should consider the increased potential (in adolescents as compared with adults) for weight gain and hyperlipidemia. Clinicians should consider the potential long-term risks when prescribing to adolescents, and in many cases this may lead them to consider prescribing other drugs first in adolescents [see Warnings and Precautions ( 5.5,5.6)].
    Information describing the use of olanzapine tablets in pediatric patients with schizophrenia is approved for Eli Lilly and Company's olanzapine drug product labeling. However, due to Eli Lilly and Company's marketing exclusivity rights, this drug product is not labeled with that pediatric information.

    1.2 Bipolar I Disorder (Manic or Mixed Episodes)
    Monotherapy
    Olanzapine Tablets USP are indicated for the acute treatment of manic or mixed episodes associated with bipolar I disorder and maintenance treatment of bipolar I disorder. Efficacy was established in three clinical trials in adult patients with manic or mixed episodes of bipolar I disorder: two 3- to 4-week trials and one monotherapy maintenance trial [see Clinical Studies ( 14.2)].
    When deciding among the alternative treatments for adolescents, clinicians should consider the increased potential (in adolescents as compared with adults) for weight gain and hyperlipidemia. Clinicians should consider the potential long-term risks when prescribing to adolescents, and in many cases this may lead them to consider prescribing other drugs first in adolescents [see Warnings and Precautions ( 5.5,5.6)].
    Information describing the use of olanzapine tablets in pediatric patients with bipolar I disorder is approved for Eli Lilly and Company's olanzapine drug product labeling. However, due to Eli Lilly and Company's marketing exclusivity rights, this drug product is not labeled with that pediatric information.
    Adjunctive Therapy to Lithium or Valproate
    Olanzapine Tablets USP are indicated for the treatment of manic or mixed episodes associated with bipolar I disorder as an adjunct to lithium or valproate. Efficacy was established in two 6-week clinical trials in adults. The effectiveness of adjunctive therapy for longer-term use has not been systematically evaluated in controlled trials [see Clinical Studies ( 14.2)].

    1.3 Special Considerations in Treating Pediatric Schizophrenia and Bipolar I Disorder
    Information on treating pediatric patients with schizophrenia and bipolar I disorder is approved for Eli Lilly and Company's olanzapine drug product labeling. However, due to Eli Lilly and Company's marketing exclusivity rights, this drug product is not labeled with that pediatric information.

    1.5 Olanzapine and Fluoxetine in Combination: Depressive Episodes Associated with Bipolar I Disorder
    Oral olanzapine and fluoxetine in combination is indicated for the treatment of depressive episodes associated with bipolar I disorder, based on clinical studies in adult patients.

    Olanzapine monotherapy is not indicated for the treatment depressive episodes associated with bipolar I disorder.
    Close
  • DOSAGE & ADMINISTRATION

    2.1 Schizophrenia
    Adults
    Dose Selection
    Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 5 to 10 mg initially, with a target dose of 10 mg/day within several days. Further dosage adjustments, if indicated, should generally occur at intervals of not less than 1 week, since steady state for olanzapine would not be achieved for approximately 1 week in the typical patient. When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended.
    Efficacy in schizophrenia was demonstrated in a dose range of 10 to 15 mg/day in clinical trials. However, doses above 10 mg/day were not demonstrated to be more efficacious than the 10 mg/day dose. An increase to a dose greater than the target dose of 10 mg/day (i.e., to a dose of 15 mg/day or greater) is recommended only after clinical assessment. Olanzapine is not indicated for use in doses above 20 mg/day.
    Dosing in Special Populations
    The recommended starting dose is 5 mg in patients who are debilitated, who have a predisposition to hypotensive reactions, who otherwise exhibit a combination of factors that may result in slower metabolism of olanzapine (e.g., nonsmoking female patients greater than or equal to 65 years of age), or who may be more pharmacodynamically sensitive to olanzapine [see Warnings and Precautions ( 5.14), Drug Interactions (7), and Clinical Pharmacology (12.3)]. When indicated, dose escalation should be performed with caution in these patients.
    Maintenance Treatment
    The effectiveness of oral olanzapine, 10 mg/day to 20 mg/day, in maintaining treatment response in schizophrenic patients who had been stable on olanzapine for approximately 8 weeks and were then followed for relapse has been demonstrated in a placebo-controlled trial [see Clinical Studies ( 14.1)]. The physician who elects to use olanzapine for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.
    Adolescents
    Pediatric dosing information in pediatric patients with schizophrenia is approved for Eli Lilly and Company's olanzapine drug product labeling. However, due to Eli Lilly and Company's marketing exclusivity rights, this drug product is not labeled with that pediatric information.

    2.2 Bipolar I Disorder (Manic or Mixed Episodes)
    Adults
    Dose Selection for Monotherapy
    Oral olanzapine should be administered on a once-a-day schedule without regard to meals, generally beginning with 10 or 15 mg. Dosage adjustments, if indicated, should generally occur at intervals of not less than 24 hours, reflecting the procedures in the placebo-controlled trials. When dosage adjustments are necessary, dose increments/decrements of 5 mg QD are recommended.
    Short-term (3 to 4 weeks) antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials. The safety of doses above 20 mg/day has not been evaluated in clinical trials [see Clinical Studies ( 14.2)].
    Maintenance Monotherapy
    The benefit of maintaining bipolar I patients on monotherapy with oral olanzapine at a dose of 5 to 20 mg/day, after achieving a responder status for an average duration of 2 weeks, was demonstrated in a controlled trial [see Clinical Studies ( 14.2)]. The physician who elects to use olanzapine for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.
    Dose Selection for Adjunctive Treatment
    When administered as adjunctive treatment to lithium or valproate, oral olanzapine dosing should generally begin with 10 mg once-a-day without regard to meals.
    Antimanic efficacy was demonstrated in a dose range of 5 mg to 20 mg/day in clinical trials [see Clinical Studies ( 14.2)]. The safety of doses above 20 mg/day has not been evaluated in clinical trials.
    Adolescents
    Pediatric dosing information in pediatric patients with bipolar I disorder is approved for Eli Lilly and Company's olanzapine drug product labeling. However, due to Eli Lilly and Company's marketing exclusivity rights, this drug product is not labeled with that pediatric information.

    2.5 Olanzapine and Fluoxetine in Combination: Depressive Episodes Associated with Bipolar I Disorder
    When using olanzapine and fluoxetine in combination, also refer to the Clinical Studies section of the package insert for olanzapine and fluoxetine in combination.
    Oral olanzapine should be administered in combination with fluoxetine once daily in the evening, without regard to meals, generally beginning with 5 mg of oral olanzapine and 20 mg of fluoxetine. Dosage adjustments, if indicated, can be made according to efficacy and tolerability within dose ranges of oral olanzapine 5 to 12.5 mg and fluoxetine 20 to 50 mg. Antidepressant efficacy was demonstrated with olanzapine and fluoxetine in combination in adult patients with a dose range of olanzapine 6 to 12 mg and fluoxetine 25 to 50 mg.
    Safety and efficacy of olanzapine and fluoxetine in combination was determined in clinical trials supporting approval of olanzapine and fluoxetine in combination. Olanzapine and fluoxetine in combination is dosed between 3 mg/25 mg (olanzapine/fluoxetine) per day and 12 mg/50 mg (olanzapine/fluoxetine) per day. The following table demonstrates the appropriate individual component doses of olanzapine and fluoxetine versus olanzapine and fluoxetine in combination. Dosage adjustments, if indicated, should be made with the individual components according to efficacy and tolerability.

    While there is no body of evidence to answer the question of how long a patient treated with olanzapine and fluoxetine in combination should remain on it, it is generally accepted that bipolar I disorder, including the depressive episodes associated with bipolar I disorder, is a chronic illness requiring chronic treatment. The physician should periodically reexamine the need for continued pharmacotherapy.
    Safety of coadministration of doses above 18 mg olanzapine with 75 mg fluoxetine has not been evaluated in clinical studies.
    Olanzapine monotherapy is not indicated for the treatment of depressive episodes associated with bipolar I disorder.

    2.7 Olanzapine and Fluoxetine in Combination: Dosing in Special Populations
    The starting dose of oral olanzapine 2.5 to 5 mg with fluoxetine 20 mg should be used for patients with a predisposition to hypotensive reactions, patients with hepatic impairment, or patients who exhibit a combination of factors that may slow the metabolism of olanzapine or fluoxetine in combination (female gender, geriatric age, nonsmoking status), or those patients who may be pharmacodynamically sensitive to olanzapine. Dosing modification may be necessary in patients who exhibit a combination of factors that may slow metabolism. When indicated, dose escalation should be performed with caution in these patients. Olanzapine and fluoxetine in combination have not been systematically studied in patients over 65 years of age or in patients < 18 years of age [see Warnings and Precautions ( 5.14), Drug Interactions (7), and Clinical Pharmacology (12.3)].

  • WARNINGS AND PRECAUTIONS

    When using olanzapine and fluoxetine in combination, also refer to the Warnings and Precautions section of the package insert for olanzapine and fluoxetine in combination.

    5.1 Elderly Patients with Dementia-Related Psychosis
    Increased Mortality
    Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions (5.14), and Patient Counseling Information (17.2)].
    In placebo-controlled clinical trials of elderly patients with dementia-related psychosis, the incidence of death in olanzapine-treated patients was significantly greater than placebo-treated patients (3.5% vs 1.5%, respectively).
    Cerebrovascular Adverse Events (CVAE), Including Stroke
    Cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, were reported in patients in trials of olanzapine in elderly patients with dementia-related psychosis. In placebo-controlled trials, there was a significantly higher incidence of cerebrovascular adverse events in patients treated with olanzapine compared to patients treated with placebo. Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning and Patient Counseling Information ( 17.2)].

    5.2 Suicide
    The possibility of a suicide attempt is inherent in Schizophrenia and in Bipolar I Disorder, and close supervision of high-risk patients should accompany drug therapy. Prescriptions for olanzapine should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce the risk of overdose.

    5.3 Neuroleptic Malignant Syndrome (NMS)
    A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with administration of antipsychotic drugs, including olanzapine. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac dysrhythmia). Additional signs may include elevated creatinine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.
    The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to exclude cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system pathology.
    The management of NMS should include: 1) immediate discontinuation of antipsyhcotic drugs and other drugs not essential to concurrent therapy; 2) intensive symptomatic treatment and medical monitoring; and 3) treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for NMS.
    If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. The patient should be carefully monitored, since recurrences of NMS have been reported [see Patient Counseling Information ( 17.3)].

    5.4 Hyperglycemia
    Physicians should consider the risks and benefits when prescribing olanzapine to patients with an established diagnosis of diabetes mellitus, or having borderline increased blood glucose level (fasting 100 to 126 mg/dL, non-fasting 140 to 200 mg/dL). Patients taking olanzapine should be monitored regularly for worsening of glucose control. Patients starting treatment with olanzapine should undergo fasting blood glucose testing at the beginning of treatment and periodically during treatment. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyhagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when the atypical antipsychotic was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuatino of the suspect drug [see Patient Counseling Information( 17.4)].
    Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics including olanzapine. Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. Epidemiological studies suggest an increased risk of treatment-emergent hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics. While relative risk estimates are inconsistent, the association between atypical antipsychotics and increases in glucose levels appears to fall on a continuum and olanzapine appears to have a greater association than some other atypical antipsychotics.
    Mean increases in blood glucose have been observed in patients treated (median exposure of 9.2 months) with olanzapine in phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE). The mean increase of serum glucose (fasting and nonfasting samples) from baseline to the average of the 2 highest serum concentrations was 15 mg/dL.
    In a study of healthy volunteers, subjects who received olanzapine (N = 22) for 3 weeks had a mean increase compared to baseline in fasting blood glucose of 2.3 mg/dL. Placebo-treated subjects (N = 19) had a mean increase in fasting blood glucose compared to baseline of 0.34 mg/dL.
    Olanzapine Monotherapy in Adults
    In an analysis of 5 placebo-controlled adult olanzapine monotherapy studies with a median treatment duration of approximately 3 weeks, olanzapine was associated with a greater mean change in fasting glucose levels compared to placebo (2.76 mg/dL versus 0.17 mg/dL). The difference in mean changes between olanzapine and placebo was greater in patients with evidence of glucose dysregulation at baseline (patients diagnosed with diabetes mellitus or related adverse reactions, patients treated with anti-diabetic agents, patients with a baseline random glucose level greater than or equal to 200 mg/dL, and/or a baseline fasting glucose level greater than or equal to 126 mg/dL). Olanzapine-treated patients had a greater mean HbA1c increase from baseline of 0.04% (median exposure 21 days), compared to a mean HbA1c decrease of 0.06% in placebo-treated subjects (median exposure 17 days).
    In an analysis of 8 placebo-controlled studies (median treatment exposure 4 to 5 weeks), 6.1% of olanzapine-treated subjects (N = 855) had treatment-emergent glycosuria compared to 2.8% of placebo-treated subjects (N = 599). Table 2 shows short-term and long-term changes in fasting glucose levels from adult olanzapine monotherapy studies.

    The mean change in fasting glucose for patients exposed at least 48 weeks was 4.2 mg/dL (N = 487). In analyses of patients who completed 9 to 12 months of olanzapine therapy, mean change in fasting and nonfasting glucose levels continued to increase over time.
    Olanzapine Monotherapy in Adolescents
    The safety and efficacy of olanzapine have not been established in patients under the age of 13 years. In an analysis of 3 placebo-controlled olanzapine monotherapy studies of adolescent patients, including those with schizophrenia (6 weeks) or bipolar I disorder (manic or mixed episodes) (3 weeks), olanzapine was associated with a greater mean change from baseline in fasting glucose levels compared to placebo (2.68 mg/dL versus -2.59 mg/dL). The mean change in fasting glucose for adolescents exposed at least 24 weeks was 3.1 mg/dL (N = 121). Table 3 shows short-term and long-term changes in fasting blood glucose from adolescent olanzapine monotherapy studies.

    5.5 Hyperlipidemia
    Undesirable alterations in lipids have been observed with olanzapine use. Clinical monitoring, including baseline and periodic follow-up lipid evaluations in patients using olanzapine, is recommended [see Patient Counseling Information ( 17.5)].
    Clinically significant, and sometimes very high (> 500 mg/dL), elevations in triglyceride levels have been observed with olanzapine use. Modest mean increases in total cholesterol have also been seen with olanzapine use.
    Olanzapine Monotherapy in Adults
    In an analysis of 5 placebo-controlled olanzapine monotherapy studies with treatment duration up to 12 weeks, olanzapine-treated patients had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.3 mg/dL, 3 mg/dL, and 20.8 mg/dL respectively compared to decreases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 6.1 mg/dL, 4.3 mg/dL, and 10.7 mg/dL for placebo-treated patients. For fasting HDL cholesterol, no clinically meaningful differences were observed between olanzapine-treated patients and placebo-treated patients. Mean increases in fasting lipid values (total cholesterol, LDL cholesterol, and triglycerides) were greater in patients without evidence of lipid dysregulation at baseline, where lipid dysregulation was defined as patients diagnosed with dyslipidemia or related adverse reactions, patients treated with lipid lowering agents, or patients with high baseline lipid levels.
    In long-term studies (at least 48 weeks), patients had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.6 mg/dL, 2.5 mg/dL, and 18.7 mg/dL, respectively, and a mean decrease in fasting HDL cholesterol of 0.16 mg/dL. In an analysis of patients who completed 12 months of therapy, the mean nonfasting total cholesterol did not increase further after approximately 4 to 6 months.
    The proportion of patients who had changes (at least once) in total cholesterol, LDL cholesterol or triglycerides from normal or borderline to high, or changes in HDL cholesterol from normal or borderline to low, was greater in long-term studies (at least 48 weeks) as compared with short-term studies. Table 4 shows categorical changes in fasting lipids values.

    In phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE), over a median exposure of 9.2 months, the mean increase in triglycerides in patients taking olanzapine was 40.5 mg/dL. In phase 1 of CATIE, the mean increase in total cholesterol was 9.4 mg/dL.
    Olanzapine Monotherapy in Adolescents
    The safety and efficacy of olanzapine have not been established in patients under the age of 13 years. In an analysis of 3 placebo-controlled olanzapine monotherapy studies of adolescents, including those with schizophrenia (6 weeks) or bipolar I disorder (manic or mixed episodes) (3 weeks), olanzapine-treated adolescents had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 12.9 mg/dL, 6.5 mg/dL, and 28.4 mg/dL, respectively, compared to increases from baseline in mean fasting total cholesterol and LDL cholesterol of 1.3 mg/dL and 1.0 mg/dL, and a decrease in triglycerides of 1.1 mg/dL for placebo-treated adolescents. For fasting HDL cholesterol, no clinically meaningful differences were observed between olanzapine-treated adolescents and placebo-treated adolescents.
    In long-term studies (at least 24 weeks), adolescents had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.5 mg/dL, 5.4 mg/dL, and 20.5 mg/dL, respectively, and a mean decrease in fasting HDL cholesterol of 4.5 mg/dL. Table 5 shows categorical changes in fasting lipids values in adolescents.

    5.6 Weight Gain
    Potential consequences of weight gain should be considered prior to starting olanzapine. Patients receiving olanzapine should receive regular monitoring of weight [see Patient Counseling Information ( 17.6)].
    Olanzapine Monotherapy in Adults
    In an analysis of 13 placebo-controlled olanzapine monotherapy studies, olanzapine-treated patients gained an average of 2.6 kg (5.7 lb), compared to an average 0.3 kg (0.6 lb) weight loss in placebo-treated patients with a median exposure to event of 6 weeks; 22.2% of olanzapine-treated patients gained at least 7% of their baseline weight, compared to 3% of placebo-treated patients, with a median exposure to event of 8 weeks; 4.2% of olanzapine-treated patients gained at least 15% of their baseline weight, compared to 0.3% of placebo-treated patients, with a median exposure to event of 12 weeks. Clinically significant weight gain was observed across all baseline Body Mass Index (BMI) categories. Discontinuation due to weight gain occurred in 0.2% of olanzapine-treated patients and in 0% of placebo-treated patients.
    In long-term studies (at least 48 weeks), the mean weight gain was 5.6 kg (12.3 lb) (median exposure of 573 days, N = 2021). The percentages of patients who gained at least 7%, 15%, or 25% of their baseline body weight with long-term exposure were 64%, 32%, and 12%, respectively. Discontinuation due to weight gain occurred in 0.4% of olanzapine-treated patients following at least 48 weeks of exposure.
    Table 6 includes data on adult weight gain with olanzapine pooled from 86 clinical trials. The data in each column represent data for those patients who completed treatment periods of the durations specified.

    Olanzapine Monotherapy in Adolescents
    The safety and efficacy of olanzapine have not been established in patients under the age of 13 years. Mean increase in weight in adolescents was greater than in adults. In 4 placebo-controlled trials, discontinuation due to weight gain occurred in 1% of olanzapine-treated patients, compared to 0% of placebo-treated patients.

    In long-term studies (at least 24 weeks), the mean weight gain was 11.2 kg (24.6 lb); (median exposure of 201 days, N=179). The percentages of adolescents who gained at least 7%, 15%, or 25% of their baseline body weight with long-term exposure were 89%, 55%, and 29%, respectively. Among adolescent patients, mean weight gain by baseline BMI category was 11.5 kg (25.3 lb).
    12.1 kg (26.6 lb), and 12.7 kg (27.9 lb), respectively, for normal (N = 106), overweight (N = 26) and obese (N = 17). Discontinuation due to weight gain occurred in 2.2% of olanzapine-treated patients following at least 24 weeks of exposure.
    Table 8 shows data on adolescent weight gain with olanzapine pooled from 6 clinical trials. The data in each column represent data for those patients who completed treatment periods of the durations specified. Little clinical trial data is available on weight gain in adolescents with olanzapine beyond 6 months of treatment.

    5.7 Tardive Dyskinesia
    A syndrome of potentially irreversible, involuntary, dyskinetic movements may develop in patients treated with antipsychotic drugs. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown.
    The risk of developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase. However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses or may even arise after discontinuation of treatment.
    There is no known treatment for established cases of tardive dyskinesia, although the syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn. Antipsychotic treatment, itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome and thereby may possibly mask the underlying process. The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown.
    Given these considerations, olanzapine should be prescribed in a manner that is most likely to minimize the occurrence of tardive dyskinesia. Chronic antipsychotic treatment should generally be reserved for patients (1) who suffer from a chronic illness that is known to respond to antipsychotic drugs, and (2) for whom alternative, equally effective, but potentially less harmful treatments are not available or appropriate. In patients who do require chronic treatment, the smallest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. The need for continued treatment should be reassessed periodically.
    If signs and symptoms of tardive dyskinesia appear in a patient on olanzapine, drug discontinuation should be considered. However, some patients may require treatment with olanzapine despite the presence of the syndrome.
    For specific information about the warnings of lithium or valproate, refer to the Warnings section of the package inserts for these other products.

    5.8 Orthostatic Hypotension
    Olanzapine may induce orthostatic hypotension associated with dizziness, tachycardia, bradycardia and, in some patients, syncope, especially during the initial dose-titration period, probably reflecting itsantagonistic properties [see Patient Counseling Information ( 17.7)].
    For oral olanzapine therapy, the risk of orthostatic hypotension and syncope may be minimized by initiating therapy with 5 mg QD [see Dosage and Administration ( 2)]. A more gradual titration to the target dose should be considered if hypotension occurs.
    Syncope was reported in 0.6% (15/2500) of olanzapine-treated patients in phase 2 to 3 oral olanzapine studies. The risk for this sequence of hypotension, bradycardia, and sinus pause may be greater in nonpsychiatric patients compared to psychiatric patients who are possibly more adapted to certain effects of psychotropic drugs.
    Olanzapine should be used with particular caution in patients with known cardiovascular disease (history of myocardial infarction or ischemia, heart failure, or conduction abnormalities), cerebrovascular disease, and conditions which would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medications) where the occurrence of syncope, or hypotension and/or bradycardia might put the patient at increased medical risk.
    Caution is necessary in patients who receive treatment with other drugs having effects that can induce hypotension, bradycardia, respiratory or central nervous system depression [see Drug Interactions ( 7)].

    5.9 Leukopenia, Neutropenia, and Agranulocytosis
    Class Effect
    In clinical trial and/or postmarketing experience, events of leukopenia/neutropenia have been reported temporally related to antipsychotic agents, including olanzapine. Agranulocytosis has also been reported.
    Possible risk factors for leukopenia/neutropenia include preexisting low white blood cell count (WBC) and history of drug induced leukopenia/neutropenia. Patients with a history of a clinically significant low WBC or drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and discontinuation of olanzapine should be considered at the first sign of a clinically significant decline in WBC in the absence of other causative factors.
    Patients with clinically significant neutropenia should be carefully monitored for fever or other symptoms or signs of infection and treated promptly if such symptoms or signs occur. Patients with severe neutropenia (absolute neutrophil count < 1000/mm3) should discontinue olanzapine and have their WBC followed until recovery.

    5.10 Dysphagia
    Esophageal dysmotility and aspiration have been associated with antipsychotic drug use. Aspiration pneumonia is a common cause of morbidity and mortality in patients with advanced Alzheimerdisease. Olanzapine is not approved for the treatment of patients with Alzheimerdisease.

    5.11 Seizures
    During premarketing testing, seizures occurred in 0.9% (22/2500) of olanzapine-treated patients. There were confounding factors that may have contributed to the occurrence of seizures in many of these cases. Olanzapine should be used cautiously in patients with a history of seizures or with conditions that potentially lower the seizure threshold, e.g., Alzheimerdementia. Olanzapine is not approved for the treatment of patients with Alzheimerdisease. Conditions that lower the seizure threshold may be more prevalent in a population of 65 years or older.

    5.12 Potential for Cognitive and Motor Impairment
    Somnolence was a commonly reported adverse reaction associated with olanzapine treatment, occurring at an incidence of 26% in olanzapine patients compared to 15% in placebo patients. This adverse reaction was also dose related. Somnolence led to discontinuation in 0.4% (9/2500) of patients in the premarketing database.
    Since olanzapine has the potential to impair judgment, thinking, or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine therapy does not affect them adversely [see Patient Counseling Information ( 17.8)].

    5.13 Body Temperature Regulation
    Disruption of the bodyability to reduce core body temperature has been attributed to antipsychotic agents. Appropriate care is advised when prescribing olanzapine for patients who will be experiencing conditions which may contribute to an elevation in core body temperature, e.g., exercising strenuously, exposure to extreme heat, receiving concomitant medication with anticholinergic activity, or being subject to dehydration [see Patient Counseling Information ( 17.9)].

    5.14 Use in Patients with Concomitant Illness
    Clinical experience with olanzapine in patients with certain concomitant systemic illnesses is limited [see Clinical Pharmacology ( 12.3)].
    Olanzapine exhibits in vitro muscarinic receptor affinity. In premarketing clinical trials with olanzapine, olanzapine was associated with constipation, dry mouth, and tachycardia, all adverse reactions possibly related to cholinergic antagonism. Such adverse reactions were not often the basis for discontinuations from olanzapine, but olanzapine should be used with caution in patients with clinically significant prostatic hypertrophy, narrow angle glaucoma, or a history of paralytic ileus or related conditions.
    In 5 placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis (N = 1184), the following treatment-emergent adverse reactions were reported in olanzapine-treated patients at an incidence of at least 2% and significantly greater than placebo-treated patients: falls, somnolence, peripheral edema, abnormal gait, urinary incontinence, lethargy, increased weight, asthenia, pyrexia, pneumonia, dry mouth and visual hallucinations. The rate of discontinuation due to adverse reactions was significantly greater with olanzapine than placebo (13% vs 7%). Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo. Olanzapine is not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning, Warnings and Precautions ( 5.1), and Patient Counseling Information (17.2)].
    Olanzapine has not been evaluated or used to any appreciable extent in patients with a recent history of myocardial infarction or unstable heart disease. Patients with these diagnoses were excluded from premarketing clinical studies. Because of the risk of orthostatic hypotension with olanzapine, caution should be observed in cardiac patients [see Warnings and Precautions ( 5.8)].

    5.15 Hyperprolactinemia
    As with other drugs that antagonize dopamine D2 receptors, olanzapine elevates prolactin levels, and a modest elevation persists during chronic administration. Hyperprolactinemia may suppress hypothalamic GnRH, resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male subjects.
    Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin dependent in vitro, a factor of potential importance if the prescription of these drugs is contemplated in a patient with previously detected breast cancer. As is common with compounds which increase prolactin release, an increase in mammary gland neoplasia was observed in the olanzapine carcinogenicity studies conducted in mice and rats [see Nonclinical Toxicology ( 13.1
    In placebo-controlled olanzapine clinical studies (up to 12 weeks), changes from normal to high in prolactin concentrations were observed in 30% of adults treated with olanzapine as compared to 10.5% of adults treated with placebo. In a pooled analysis from clinical studies including 8136 adults treated with olanzapine, potentially associated clinical manifestations included menstrual-related events1 (2% [49/3240] of females), sexual function-related events2 (2% [150/8136] of females and males), and breast-related events3 (0.7% [23/3240] of females, 0.2% [9/4896] of males).
    In placebo-controlled olanzapine monotherapy studies in adolescent patients (up to 6 weeks) with schizophrenia or bipolar I disorder (manic or mixed episodes), changes from normal to high in prolactin concentrations were observed in 47% of olanzapine-treated patients compared to 7% of placebo-treated patients. In a pooled analysis from clinical trials including 454 adolescents treated with olanzapine, potentially associated clinical manifestations included menstrual-related events1 (1% [2/168] of females), sexual function-related events2 (0.7% [3/454 of females and males), and breast-related events3 (2% [3/168] of females, 2% [7/286] of males) [see Use in Specific Populations ( 8.4)].

    2 Based on a search of the following terms: anorgasmia, delayed ejaculation, erectile dysfunction, decreased libido, loss of libido, abnormal orgasm, and sexual dysfunction.
    3 Based on a search of the following terms: breast discharge, enlargement or swelling, galactorrhea, gynecomastia, and lactation disorder.

    5.16 Use in Combination with Fluoxetine, Lithium or Valproate
    When using olanzapine and fluoxetine in combination, the prescriber should also refer to the Warnings and Precautions section of the package insert for olanzapine and fluoxetine in combination.
    When using olanzapine in combination with lithium or valproate, the prescriber should refer to the Warnings and Precautions sections of the package inserts for lithium or valproate. [See Drug Interactions ( 7)].

    When using olanzapine and fluoxetine in combination, also refer to the Adverse Reactions section of the package insert for olanzapine and fluoxetine in combination.

    6.1 Clinical Trials Experience
    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect or predict the rates observed in practice.
    Clinical Trials in Adults
    The information below is derived from a clinical trial database for olanzapine consisting of 8661 adult patients with approximately 4165 patient-years of exposure to olanzapine. This database includes: (1) 2500 patients who participated in multiple-dose oral olanzapine premarketing trials in Schizophrenia and Alzheimer's disease representing approximately 1122 patient-years of exposure as of February 14, 1995; (2) 182 patients who participated in oral olanzapine premarketing Bipolar I Disorder (manic or mixed episodes) trials representing approximately 66 patient-years of exposure; (3) 191 patients who participated in an oral olanzapine trial of patients having various psychiatric symptoms in association with Alzheimer's disease representing approximately 29 patient-years of exposure; and (4) 5788 patients from 88 additional oral olanzapine clinical trials as of December 31, 2001. In addition, information from the premarketing 6-week clinical study database for olanzapine in combination with lithium or valproate, consisting of 24 patients who participated in Bipolar I Disorder (manic or mixed episodes) trials with approximately 22 patient-years of exposure, is included below.
    The conditions and duration of treatment with olanzapine varied greatly and included (in overlapping categories) open-label and double-blind phases of studies, inpatients and outpatients, fixed-dose and dose-titration studies, and short-term or longer-term exposure. Adverse reactions were assessed by collecting adverse reactions, results of physical examinations, vital signs, weights, laboratory analytes, ECGs, chest x-rays, and results of ophthalmologic examinations.
    Certain portions of the discussion below relating to objective or numeric safety parameters, namely, dose-dependent adverse reactions, vital sign changes, weight gain, laboratory changes, and ECG changes are derived from studies in patients with Schizophrenia and have not been duplicated for Bipolar I Disorder (manic or mixed episodes) or agitation. However, this information is also generally applicable to Bipolar I Disorder (manic or mixed episodes) and agitation.
    Adverse reactions during exposure were obtained by spontaneous report and recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse reactions without first grouping similar types of reactions into a smaller number of standardized reaction categories. In the tables and tabulations that follow, MedDRA and COSTART Dictionary terminology has been used to classify reported adverse reactions.
    The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse reaction of the type listed. A reaction was considered treatment emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. The reported reactions do not include those reaction terms that were so general as to be uninformative. Reactions listed elsewhere in labeling may not be repeated below. It is important to emphasize that, although the reactions occurred during treatment with olanzapine, they were not necessarily caused by it. The entire label should be read to gain a complete understanding of the safety profile of olanzapine.
    The prescriber should be aware that the figures in the tables and tabulations cannot be used to predict the incidence of side effects in the course of usual medical practice where patient characteristics and other factors differ from those that prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses, and investigators. The cited figures, however, do provide the prescribing physician with some basis for estimating the relative contribution of drug and nondrug factors to the adverse reactions incidence in the population studied.
    Incidence of Adverse Events in Short-Term, Placebo-Controlled and Combination Trials
    The following findings are based on premarketing trials of oral olanzapine for Schizophrenia, Bipolar I Disorder (manic or mixed episodes), a subsequent trial of patients having various psychiatric symptoms in association with Alzheimer's disease, and premarketing combination trials.
    Adverse Reactions Associated with Discontinuation of Treatment in Short-Term, Placebo-Controlled Trials
    Schizophrenia
    Overall, there was no difference in the incidence of discontinuation due to adverse events (5% for oral olanzapine vs. 6% for placebo). However, discontinuations due to increases in ALT were considered to be drug related (2% for oral olanzapine vs. 0% for placebo).
    Bipolar I Disorder (Manic or Mixed Episodes) Monotherapy
    Overall, there was no difference in the incidence of discontinuation due to adverse events (2% for olanzapine vs. 2% for placebo).
    Adverse Reactions Associated with Discontinuation of Treatment in Short-Term Combination Trials
    Bipolar I Disorder(Manic or Mixed Episodes), Olanzapine in Combination with Lithium or Valproate
    In a study of patients who were already tolerating either lithium or valproate as monotherapy, discontinuation rates due to adverse reactions were 11% for the combination of oral olanzapine with lithium or valproate compared to 2% for patients who remained on lithium or valproate monotherapy. Discontinuations with the combination of oral olanzapine and lithium or valproate that occurred in more than 1 patient were: somnolence (3%), weight gain (1%), and peripheral edema (1%).
    Commonly Observed Adverse Events in Short-Term, Placebo-Controlled Trials
    The most commonly observed adverse events associated with the use of oral olanzapine (incidence of 5% or greater) and not observed at an equivalent incidence among placebo-treated patients (olanzapine incidence at least twice that for placebo) were:

    Dystonia, Class Effect
    Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, the frequency and severity are greater with high potency and at higher doses at first generation antipsychotic drugs. In general, an elevated risk of acute dystonia may be observed in males and younger age groups receiving antipsychotics; however, events of dystonia have been reported infrequently (< 1%) with olanzapine use.

    The following table addresses dose relatedness for other adverse events using data from a schizophrenia trial involving fixed dosage ranges of olanzapine. It enumerates the percentage of patients with treatment-emergent adverse events for the three fixed-dose range groups and placebo. The data were analyzed using the Cochran-Armitage test, excluding the placebo group, and the table includes only those adverse events for which there was a trend.

    Differences among Fixed-Dose Groups Observed in Other Olanzapine Clinical Trials
    In a single 8-week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200) and 40 (N=200) mg/day of oral olanzapine in patients with Schizophrenia or Schizoaffective Disorder, differences among 3 dose groups were observed for the following safety outcomes: weight gain, prolactin elevation, fatigue and dizziness. Mean baseline to endpoint increase in weight (10 mg/day: 1.9 kg; 20 mg/day: 2.3 kg; 40 mg/day: 3 kg) was observed with significant differences between 10 vs 40 mg/day. Incidence of treatment-emergent prolactin elevation > 24.2 ng per mL (female) or > 18.77 ng mL (male) at any time during the trial (10 mg/day: 31.2%; 20 mg/day: 42.7%; 40 mg/day: 61.1%) with significant differences between 10 vs 40 mg/day and 20 vs 40 mg/day; fatigue (10 mg/day: 1.5%; 20mg/day: 2.1%; 40 mg/day: 1.6%, 40 mg/day: 6.6%) with significant differences between 20 vs 40 mg, was observed.
    Other Adverse Reactions Observed During the Clinical Trial Evaluation of Oral Olanzapine
    Following is a list of treatment-emergent adverse reactions reported by patients treated with oral olanzapine (at multiple doses greater than or equal to 1 mg/day) in clinical trials. this listing is not inteded to include rections 91) already listed in previous tables or elsewhere in labeling, (2) for which a drug cause was remote, (3) which were so general as to be uninformative, (4) which were not considered to have signifacnt clinical implications, or (5) which occurred at a rate equal to or less than placebo. Reactions are classified by body ststem using the following definitions: frequent adverse reactions are those occurring in at least 1/100 patients; infrequent adverse reactions are those occurring in 1/100 to 1/1000 patients; rare reactions are those occuring in fewer than 1/1000 patients.

    6.2 Vital Signs and Laboratory Studies
    Vital Sign Changes
    Oral olanzapine was associated with orthostatic hypotension and tachycardia in clinical trials [see Warnings and Precautions ( 5)].
    Laboratory Changes
    Olanzapine Monotherapy in Adults
    An assessment of the premarketing experience for olanzapine revealed an association with asymptomatic increases in ALT, AST, and GGT. Within the original premarketing database of about 2400 adult patients with baseline ALT less than or equal to 90 IU/L, the incidence of ALT elevations to >200 IU/L was 2% (50/2381). None of these patients experienced jaundice or other symptoms attributable to liver impairment and most had transient changes that tended to normalize while olanzapine treatment was continued.
    In placebo-controlled olanzapine monotherapy studies in adults, clinically significant ALT elevations (change from < 3 times the upper limit of normal [ULN] at baseline to greater than or equal to 3 times ULN) were observed in 5% (77/1426) of patients exposed to olanzapine compared to 1% (10/1187) of patients exposed to placebo. ALT elevations greater than or equal to 5 times ULN were observed in 2% (29/1438) of olanzapine-treated patients, compared to 0.3% (4/1196) of placebo-treated patients. ALT values returned to normal, or were decreasing, at last follow-up in the majority of patients who either continued treatment with olanzapine or discontinued olanzapine. No patient with elevated ALT values experienced jaundice, liver failure, or met the criteria for Hy's Rule.
    Rare postmarketing reports of hepatitis have been received. Very rare cases of cholestatic or mixed liver injury have also been reported in the postmarketing period.
    Caution should be exercised in patients with signs and symptoms of hepatic impairment, in patients with pre-existing conditions associated with limited hepatic functional reserve, and in patients who are being treated with potentially hepatotoxic drugs.
    Olanzapine administration was also associated with increases in serum prolactin [see Warnings and Precautions ( 5.15)], with an asymptomatic elevation of the eosinophil count in 0.3% of patients, and with an increase in CPK.
    Olanzapine Monotherapy in Adolescents
    In placebo-controlled clinical trials of adolescent patients with schizophrenia or bipolar I disorder (manic or mixed episodes), greater frequencies for the following treatment-emergent findings, at anytime, were observed in laboratory analytes compared to placebo: elevated ALT(greater than or equal to 3X ULN in patients with ALT at baseline < 3X ULN), (12% vs 2%); elevated AST (28% vs 4%); low total bilirubin (22% vs 7%); elevated GGT (10% vs 1%); and elevated prolactin (47% vs 7%).
    In placebo-controlled olanzapine monotherapy studies in adolescents, clinically significant ALT elevations (change from < 3 times ULN at baseline to greater than or equal to 3 times ULN) were observed in 12% (22/192) of patients exposed to olanzapine compared to 2% (2/109) of patients exposed to placebo. ALT elevations5 times ULN were observed in 4% (8/192) of olanzapine-treated patients, compared to 1% (1/109) of placebo-treated patients. ALT values returned to normal, or were decreasing, at last follow-up in the majority of patients who either continued treatment with olanzapine or discontinued olanzapine. No adolescent patient with elevated ALT values experienced jaundice, liver failure, or met the criteria for Hy's Rule.
    ECG Changes
    In pooled studies of adults as well as opooled studies of adolescents, there were no significant differences between olanapine and placebo in the proportions of patients experiencing potentially important changes in ECG parameters, including GT, Gtc (Frideericia corrected), and PR intervals. Olanzapine use was associated with a mean increase in heart rate compared to placebo (adults: +2.4 beats per minute vs no change with placebo; adolescents: +6.3 beats per minute vs -5.1 beats per minute was placebo). This increase in heart rate may be related to olanzapine's potential for inducing orthostatic changes [see Warnings and Precautions ( 5.8)].

    6.3 Postmarketing Experience
    The following adverse reactions have been identified during post-approval use of olanzapine. Because these reactions are reported voluntarily from a population of uncertain size, it is difficult to reliably estimate their frequency or evaluate a causal relationship to drug exposure.
    Adverse reactions reported since market introduction that were temporally (but not necessarily causally) related to olanzapine therapy include the following: allergic reaction (e.g., anaphylactoid reaction, angioedema, pruritus or urticaria), diabetic coma, diabetic ketoacidosis, discontinuation reaction (diaphoresis, nausea or vomiting), jaundice, neutropenia, pancreatitis, priapism, rash, rhabdomyolysis, and venous thromboembolic events (including pulmonary embolism and deep venous thrombosis). Random cholesterol levels of greater than or equal to 240 mg/dL and random triglyceride levels of greater than or equal to 1000 mg/dL have been reported.

  • DRUG INTERACTIONS

    The risks of using olanzapine in combination with other drugs have not been extensively evaluated in systematic studies.

    7.1 Potential for Other Drugs to Affect Olanzapine
    Diazepam
    The coadministration of diazepam with olanzapine potentiated the orthostatic hypotension observed with olanzapine [see Drug Interactions ( 7.2)].
    Cimetidine and Antacids
    Single doses of cimetidine (800 mg) or aluminum- and magnesium-containing antacids did not affect the oral bioavailability of olanzapine.
    Inducers of CYP1A2
    Carbamazepine therapy (200 mg bid) causes an approximately 50% increase in the clearance of olanzapine. This increase is likely due to the fact that carbamazepine is a potent inducer of CYP1A2 activity. Higher daily doses of carbamazepine may cause an even greater increase in olanzapine clearance.
    Alcohol
    Ethanol (45 mg/70 kg single dose) did not have an effect on olanzapine pharmacokinetics. The coadministration of alcohol (i.e., ethanol) with olanzapine potentiated the orthostatic hypotension observed with olanzapine [see Drug Interactions ( 7.2)].
    Inhibitors of CYP1A2
    Fluvoxamine: Fluvoxamine, a CYP1A2 inhibitor, decreases the clearance of olanzapine. This results in a mean increase in olanzapine Cmax following fluvoxamine of 54% in female nonsmokers and 77% in male smokers. The mean increase in olanzapine AUC is 52% and 108%, respectively. Lower doses of olanzapine should be considered in patients receiving concomitant treatment with fluvoxamine.
    Inhibitors of CYP2D6
    Fluoxetine: Fluoxetine (60 mg single dose or 60 mg daily dose for 8 days) causes a small (mean 16%) increase in the maximum concentration of olanzapine and a small (mean 16%) decrease in olanzapine clearance. The magnitude of the impact of this factor is small in comparison to the overall variability between individuals, and therefore dose modification is not routinely recommended. When using olanzapine and fluoxetine in combination, also refer to the Drug Interactions section of the package insert for olanzapine and fluoxetine in combination.
    Warfarin
    Warfarin (20 mg single dose) did not affect olanzapine pharmacokinetics [see Drug Interactions ( 7.2)].
    Inducers of CYP1A2 or Glucuronyl Transferase
    Omeprazole and rifampin may cause an increase in olanzapine clearance.
    Charcoal
    The administration of activated charcoal (1 g) reduced the Cmax and AUC of oral olanzapine by about 60%. As peak olanzapine levels are not typically obtained until about 6 hours after dosing, charcoal may be a useful treatment for olanzapine overdose.

    7.2 Potential for Olanzapine to Affect Other Drugs
    CNS Acting Drugs
    Given the primary CNS effects of olanzapine, caution should be used when olanzapine is taken in combination with other centrally acting drugs and alcohol.
    Antihypertensive Agents
    Olanzapine, because of its potential for inducing hypotension, may enhance the effects of certain antihypertensive agents.
    Levodopa and Dopamine Agonists
    Olanzapine may antagonize the effects of levodopa and dopamine agonists.
    Lithium
    Multiple doses of olanzapine (10 mg for 8 days) did not influence the kinetics of lithium. Therefore, concomitant olanzapine administration does not require dosage adjustment of lithium [see Warnings and Precautions ( 5.16)].
    Valproate
    Olanzapine (10 mg daily for 2 weeks) did not affect the steady state plasma concentrations of valproate. Therefore, concomitant olanzapine administration does not require dosage adjustment of valproate [see Warnings and Precautions ( 5.16)].
    Effect of Olanzapine on Drug Metabolizing Enzymes
    In vitro studies utilizing human liver microsomes suggest that olanzapine has little potential to inhibit CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A. Thus, olanzapine is unlikely to cause clinically important drug interactions mediated by these enzymes.
    Imipramine
    Single doses of olanzapine did not affect the pharmacokinetics of imipramine or its active metabolite desipramine.
    Warfarin
    Single doses of olanzapine did not affect the pharmacokinetics of warfarin [see Drug Interactions ( 7.1)].
    Diazepam
    Olanzapine did not influence the pharmacokinetics of diazepam or its active metabolite N-desmethyldiazepam. However, diazepam co-administered with olanzapine increased the orthostatic hypotension observed with either drug given alone [see Drug Interactions ( 7.1)].
    Alcohol
    Multiple doses of olanzapine did not influence the kinetics of ethanol [see Drug Interactions ( 7.1)].
    Biperiden
    Multiple doses of olanzapine did not influence the kinetics of biperiden.
    Theophylline
    Multiple doses of olanzapine did not affect the pharmacokinetics of theophylline or its metabolites.

  • USE IN SPECIFIC POPULATIONS

    When using olanzapine and fluoxetine in combination, also refer to the Use in Specific Populations section of the package insert for olanzapine and fluoxetine in combination.

    8.1 Pregnancy
    Teratogenic Effects
    Pregnancy Category C
    In oral reproduction studies in rats at doses up to 18 mg/kg/day and in rabbits at doses up to 30 mg/kg/day (9 and 30 times the maximum recommended human daily oral dose on a mg/m2 basis, respectively) no evidence of teratogenicity was observed. In an oral rat teratology study, early resorptions and increased numbers of nonviable fetuses were observed at a dose of 18 mg/kg/day (9 times the maximum recommended human daily oral dose on a mg/m2 basis). Gestation was prolonged at 10 mg/kg/day (5 times the maximum recommended human daily oral dose on a mg/m2 basis). In an oral rabbit teratology study, fetal toxicity (manifested as increased resorptions and decreased fetal weight) occurred at a maternally toxic dose of 30 mg/kg/day (30 times the maximum recommended human daily oral dose on a mg/m2 basis). Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
    Placental transfer of olanzapine occurs in rat pups.
    There are no adequate and well-controlled trials with olanzapine in pregnant females. Seven pregnancies were observed during clinical trials with olanzapine, including 2 resulting in normal births, 1 resulting in neonatal death due to a cardiovascular defect, 3 therapeutic abortions, and 1 spontaneous abortion.
    Non-Teratogenic Effects
    Neonates exposed to antpsychotic drugs (including olanzapine), during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. There have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder in these neonates. These complications have vaired in severity; while in some cases symptoms have been self-limited, in other cases neonates have required intentsive care unit supposrt and orlonged hospitilazation. Olanzapine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

    8.2 Labor and Delivery
    The effect of olanzapine on labor and delivery in humans is unknown. Parturition in rats was not affected by olanzapine.

    8.3 Nursing Mothers
    In a study in lactating, healthy women, olanzapine was excreted in breast milk. Mean infant dose at steady state was estimated to be 1.8% of the maternal olanzapine dose. It is recommended that women receiving olanzapine should not breast-feed.

    8.4 Pediatric Use
    Compared to patients from adult clinical trials, adolescents were likely to gain more weight, experience increased sedation, and have greater increases in total cholesterol, triglycerides, LDL cholesterol, prolactin and hepatic transaminase levels [see Warnings and Precautions ( 5.5,5.6,5.15,5.17) and Adverse Reactions (6.2)]. When deciding among the alternative treatments available for adolescents, clinicians should consider the increased potential (in adolescents as compared with adults) for weight gain and hyperlipidemia.
    Safety and effectiveness of olanzapine in children < 13 years of age have not been established [see Patient Counseling Information ( 17.13)].
    Safety and effectiveness of olanzapine and fluoxetine in combination in children and adolescents < 18 years of age have not been established.
    Pediatric use information in pediatric patients with schizophrenia and bipolar I disorder is approved for Eli Lilly and Companyolanzapine drug product labeling. However, due to Eli Lilly and Companymarketing exclusivity rights, this drug product is not labeled with that pediatric information.

    8.5 Geriatric Use
    Of the 2500 patients in premarketing clinical studies with oral olanzapine, 11% (263) were 65 years of age or over. In patients with Schizophrenia, there was no indication of any different tolerability of olanzapine in the elderly compared to younger patients. Studies in elderly patients with dementia-related psychosis have suggested that there may be a different tolerability profile in this population compared to younger patients with Schizophrenia. Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo. In placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis, there was a higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) in patients treated with olanzapine compared to patients treated with placebo. Olanzapine is not approved for the treatment of patients with dementia-related psychosis. Also, the presence of factors that might decrease pharmacokinetic clearance or increase the pharmacodynamic response to olanzapine should lead to consideration of a lower starting dose for any geriatric patient [see Boxed Warning, Dosage and Administration ( 2.1), and Warnings and Precautions (5.1)].
    Clinical studies of olanzapine and fluoxetine in combination did not include sufficient numbers in patients65 years of age to determine whether they respond differently from younger patients.

  • DRUG ABUSE AND DEPENDENCE

    9.3 Dependence
    In studies prospectively designed to assess abuse and dependence potential, olanzapine was shown to have acute depressive CNS effects but little or no potential of abuse or physical dependence in rats administered oral doses up to 15 times the maximum recommended human daily dose (20 mg) and rhesus monkeys administered oral doses up to 8 times the maximum recommended human daily dose on a mg/m2 basis.
    Olanzapine has not been systematically studied in humans for its potential for abuse, tolerance, or physical dependence. While the clinical trials did not reveal any tendency for any drug-seeking behavior, these observations were not systematic, and it is not possible to predict on the basis of this limited experience the extent to which a CNS-active drug will be misused, diverted, and/or abused once marketed. Consequently, patients should be evaluated carefully for a history of drug abuse, and such patients should be observed closely for signs of misuse or abuse of olanzapine (e.g., development of tolerance, increases in dose, drug-seeking behavior).

  • OVERDOSAGE

    10.1 Human Experience
    In premarketing trials involving more than 3100 patients and/or normal subjects, accidental or intentional acute overdosage of olanzapine was identified in 67 patients. In the patient taking the largest identified amount, 300 mg, the only symptoms reported were drowsiness and slurred speech. In the limited number of patients who were evaluated in hospitals, including the patient taking 300 mg, there were no observations indicating an adverse change in laboratory analytes or ECG. Vital signs were usually within normal limits following overdoses.
    In postmarketing reports of overdose with olanzapine alone, symptoms have been reported in the majority of cases. In symptomatic patients, symptoms with greater than or equal to 10% incidence included agitation/aggressiveness, dysarthria, tacyhcardia, various extrapryramidal symptoms, and reduced level of consciousness ranging from sedation to coma. Among less commonly reported symptoms were the following potentially medically serious reactions: aspiration, cardiopulmonary arrest, cardiac arryhthmias 9such as supraventricular tachycardia and 1 patient experiencing sinus pause with spontaneious resumption of normal rhythm), delirium, possible neuroleptic malignant syndrom, respiratory depression/arrest, conculsion, hypertension, and hypotension. Eli Lilly and Company has received reports of fatality in association with overdose of onlazapine alone. In 1 case of death, the amount of acutely ingested olanzapine was reported to be possible as low as 450 mg of otal olanzapine; however, in aother case, a patient was reported to survive an acute olanzapine ingestion of approximately 2 g of oral olanzapine.

    10.2 Management of Overdose
    The possibility of multiple drug involvement should be considered. In case of acute overdosage, establish and maintain an airway and ensure adequate oxygenation and ventilation, which may include intubation. Gastric lavage (after intubation, if patient is unconscious) and administration of activated charcoal together with a laxative should be considered. The administration of activated charcoal (1 g) reduced the Cmax and AUC of oral olanzapine by about 60%. As peak olanzapine levels are not typically obtained until about 6 hours after dosing, charcoal may be a useful treatment for olanzapine overdose.
    The possibility of obtundation, seizures, or dystonic reaction of the head and neck following overdose may create a risk of aspiration with induced emesis. Cardiovascular monitoring should commence immediately and should include continuous electrocardiographic monitoring to detect possible arrhythmias.
    There is no specific antidote to olanzapine. Therefore, appropriate supportive measures should be initiated. Hypotension and circulatory collapse should be treated with appropriate measures such as intravenous fluids and/or sympathomimetic agents. (Do not use epinephrine, dopamine, or other sympathomimetics with beta-agonist activity, since beta stimulation may worsen hypotension in the setting of olanzapine-induced alpha blockade.) Close medical supervision and monitoring should continue until the patient recovers.

  • CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action
    The mechanism of action of olanzapine, as with other drugs having efficacy in Schizophrenia, is unknown. However, it has been proposed that this drug's efficacy in Schizophrenia is mediated through a combination of dopamine and serotonin type 2 (5HT2) antagonism. The mechanism of action of olanzapine in the treatment of acute manic or mixed episodes associated with Bipolar I Disorder is unknown.

    12.2 Pharmacodynamics
    Olanzapine binds with high affinity to the following receptors: serotonin 5HT2A/2C, 5HT6 (Ki = 4, 11, and 5 nM, respectively), dopamine D1-4 (Ki=11-31 nM), histamine H1 (Ki = 7 nM), and adrenergicreceptors (Ki = 19 nM). Olanzapine is an antagonist with moderate affinity binding for serotonin 5HT3 (Ki = 57 nM) and muscarinic M1-5 (Ki = 73, 96, 132, 32, and 48 nM, respectively). Olanzapine binds weakly to GABAA, BZD, andreceptors (Ki >10
    Antagonism at receptors other than dopamine and 5HT2 may explain some of the other therapeutic and side effects of olanzapine. Olanzapineantagonism of muscarinic M1-5 receptors may explain its anticholinergic-like effects. Olanzapineantagonism of histamine H1 receptors may explain the somnolence observed with this drug. Olanzapineantagonism of adrenergicreceptors may explain the orthostatic hypotension observed with this drug.

    12.3 Pharmacokinetics
    Oral Administration, Monotherapy
    Olanzapine is well absorbed and reaches peak concentrations in approximately 6 hours following an oral dose. It is eliminated extensively by first pass metabolism, with approximately 40% of the dose metabolized before reaching the systemic circulation. Food does not affect the rate or extent of olanzapine absorption. Pharmacokinetic studies showed that olanzapine tablets and olanzapine orally disintegrating tablets dosage forms of olanzapine are bioequivalent.
    Olanzapine displaces linear kinetics over the clinical dosing range. its half-life ranges from 21 to 54 hours (5th to 95th percentile; mean of 30 hr), and apparent plasma clearance ranges from 12 to 47 L/hr (5th to 95th percentile; mean of 25 L/hr).
    Administration of olanzapine once daily leads to steady-state concentrations in about 1 week that are approximately twice the concentrations after single doses. Plasma concentrations, half-life, and clearance of olanzapine may vary between individuals on the basis of smoking status, gender, and age [see Clinical Pharmacology ( 12.3)].
    Olanzapine is extensively distributed throughout the body, with a volume of distribution of approximately 1000 L. It is 93% bound to plasma proteins over the concentration range of 7 to 1100 ng per mL, binding primarily to albumin and a1-glycoprotein.
    Metabolism and Elimination
    Following a single oral dose of 14C labeled olanzapine, 7% of the dose of olanzapine was recovered in the urine as unchanged drug, indicating that olanzapine is highly metabolized. Approximately 57% and 30% of the dose was recovered in the urine and feces, respectively. In the plasma, olanzapine accounted for only 12% of the AUC for total radioactivity, indicating significant exposure to metabolites. After multiple dosing, the major circulating metabolites were the 10-N-glucuronide, present at steady state at 44% of the concentration of olanzapine, and 4'-N-desmethyl olanzapine, present at steady state at 31% of the concentration of olanzapine. Both metabolites lack pharmacological activity at the concentrations observed.
    Direct glucuronidation and cytochrome P450 (CYP) mediated oxidation are the primary metabolic pathways for olanzapine. In vitro studies suggest that CYPs 1A2 and 2D6, and the flavin-containing monooxygenase system are involved in olanzapine oxidation. CYP2D6 mediated oxidation appears to be a minor metabolic pathway in vivo, because the clearance of olanzapine is not reduced in subjects who are deficient in this enzyme.
    Specific Populations
    Renal Impairment
    Because olanzapine is highly metabolized before excretion and only 7% of the drug is excreted unchanged, renal dysfunction alone is unlikely to have a major impact on the pharmacokinetics of olanzapine. The pharmacokinetic characteristics of olanzapine were similar in patients with severe renal impairment and normal subjects, indicating that dosage adjustment based upon the degree of renal impairment is not required. In addition, olanzapine is not removed by dialysis. The effect of renal impairment on metabolite elimination has not been studied.
    Hepatic Impairment
    Although the presence of hepatic impairment may be expected to reduce the clearance of olanzapine, a study of the effect of impaired liver function in subjects (n = 6) with clinically significant (Childs Pugh Classification A and B) cirrhosis revealed little effect on the pharmacokinetics of olanzapine.
    Geriatric
    In a study involving 24 healthy subjects, the mean elimination half-life of olanzapine was about 1.5 times greater in elderly (65 years) than in non-elderly subjects (< 65 years). Caution should be used in dosing the elderly, especially if there are other factors that might additively influence drug metabolism and/or pharmacodynamic sensitivity [see Dosage and Administration ( 2)].
    Gender
    Clearance of olanzapine is approximately 30% lower in women than in men. There were, however, no apparent differences between men and women in effectiveness or adverse effects. Dosage modifications based on gender should not be needed.
    Smoking Status
    Olanzapine clearance is about 40% higher in smokers than in nonsmokers, although dosage modifications are not routinely recommended.
    Race
    In vivo studies have shown that exposures are similar among Japanese, Chinese and Caucasians, especially after normalization for body weight differences. Dosage modifications for race are, therefore, not recommended.
    Combined Effects
    The combined effects of age, smoking, and gender could lead to substantial pharmacokinetic differences in populations. The clearance in young smoking males, for example, may be 3 times higher than that in elderly nonsmoking females. Dosing modification may be necessary in patients who exhibit a combination of factors that may result in slower metabolism of olanzapine [see Dosage and Administration ( 2)].
    Adolescents (ages 13 to 17 years)
    Pharmacokinetic information in pediatric patients is approved for Eli Lilly and Company's olanzapine drug product labeling. However, due to Eli Lilly and Company's marketing exclusivity rights, this drug product is not labeled with that pediatric information.

  • NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
    Carcinogenesis
    Oral carcinogenicity studies were conducted in mice and rats. Olazapine was administed to mice in two 78 week studies at doses of 3, 10, 30/20 mg/kg./day (equivalent to 0.8 to 5 times the maximum recommended human daily oral dose on a mg/m2 basis) and 0.25,2,8 mg/kg/day )(equivalent to 0.06 to 2 times the maximum recommended human daily oral dose on a mg/m2 basis). Rats were dosed for 2 years at doses of 0.25, 1, 2.5, 4 mg/kg/day (males) and 0.25, 1,4,8, mg/kg/day (females) (equivalent to 0.13 to 2 and o.13 to 4 times the maximum recommended human daily oral dose on a mg/m2 basis, respectively). The incidence of liver hemangiomas and hemangiosarcomas was significantly increased in 1 mouse study in female mice dosed at 8 mg/kg/day (2 times the maximum recommended human daily oral dose on a mg/m2 basis). These tumors were nt increased in another mouse study in females dosed at 10 or 30/20/mg/kg/day (2 to 5 times the maximum recommended human daily oral dose on a mg/m2 basis); in this study, there was a high incidence of early mortalities in males of the 30/20 mg/kg/day group. The incidence of mammary gland adenomas and adenocarcinomas was signifacntly increased in female mice dosed at greater than or equal to 2 mg/kg/day and in female rats dosed at greater than or equal to 4 mg/kg/day (0.5 and 2 times the maximum recommended human daily dose on a mg/m2 basis, recpectively). Antipsycholtic drugs have been shown to chronically elevate prolactin levels in rodents. Serum prolactin levels were not measured during the olanzapine carcinogencity studies; however, measurements during subchronic toxicity studies showed that olanzapine elevated serum prolactin levels up to 4 fold in rats at the same doses used in the carcinogenicity study. An increase in mammary gland neoplasms has been found in rodents after chronic administration of other antipsychotic drugs and is considered to be prolactin mediated. The relevance for himan risk of the findig of prolactin mediated endocrine tumors in rodents is unknown [see Warnings and Precautions 5.15)].
    Mutagenesis
    No evidence of genotoxic potential for olanzapine was found in the Ames reverse mutation test, in vivo micronucleus test in mice, the chromosomal aberration test in Chinese hamster ovary cells, unscheduled DNA synthesis test in rat hepatocytes, induction of forward mutation test in mouse lymphoma cells, or in vivo sister chromatid exchange test in bone marrow of Chinese hamsters.
    Impairment of Fertility
    In am oral fertility and repoductive performance study in rats, male mating performance, but not fertility, was impaired at a dose of 22.4 mg/kg/day and female fertility was decreased at a dose of 3 mg/kg/day (11 and 1.5 times the maximum recommended human daily oral dose on mg/m2 basis respectively). Discontinuance of olazapine treatment reversed the effects on male mating performance. In female rats, the precoital period was increased and the mating index reduced at 5 mg/kg/day (2.5 times the maximum recommended human daily oral dose on a mg/m2 basis). Diestrous was prolonged and estrous delayed at 1.1 mg/kg/day (0.6 times the maximum recommended human daily oral dose on a mg/m2 basis); therefore olanzapine may produce a delay in ovulation.

    13.2 Animal Toxicology and/or Pharmacology
    In animal studies with olanzapine, the principal hematologic findings were reversible peripheral cytopenias in individual dogs dosed at 10 mg/kg (17 times the maximum recommended human daily oral dose on a mg/m2 basis), dose-related decreases in lymphocytes and neutrophils in mice, and lymphopenia in rats. A few dogs treated with 10 mg/kg developed reversible neutropenia and/or reversible hemolytic anemia between 1 and 10 months of treatment. Dose-related decreases in lymphocytes and neutrophils were seen in mice given doses of 10 mg/kg (equal to 2 times the maximum recommended human daily oral dose on a mg/m2 basis) in studies of 3 monthsduration. Nonspecific lymphopenia, consistent with decreased body weight gain, occurred in rats receiving
    22.5 mg/kg (11 times the maximum recommended human daily oral dose on a mg/m2 basis) for 3 months or 16 mg/kg (8 times the maximum recommended human daily oral dose on a mg/m2 basis) for 6 or 12 months. No evidence of bone marrow cytotoxicity was found in any of the species examined. Bone marrows were normocellular or hypercellular, indicating that the reductions in circulating blood cells were probably due to peripheral (non-marrow) factors.

  • CLINICAL STUDIES

    When using olanzapine and fluoxetine in combination, also refer to the Clinical Studies section of the package insert for olanzapine and fluoxetine in combination.

    14.1 Schizophrenia
    Adults
    The efficacy of oral olanzapine in the treatment of Schizophrenia was established in 2 short-term (6 week) controlled trials of adult inpatients who met DSM III-R criteria for Schizophrenia. A single haloperidol arm was included as a comparative treatment in 1 of the 2 trials, but this trial did not compare these 2 drugs on the full range of clinically relevant doses for both.
    Several instruments were used for assessing psychiatric signs and symptoms in these studies, among them the Brief Psychiatric Rating Scale (BPRS), a multi-item inventory of general psycholpathology traditionally used to evaluate the effects of drug treatment in Schizophrenia. The BPRS psychosis cluster (conceptual disorganization, halluniatory behavior, suspiciousness, and unusual thought content) is considered a particularly useful subset for assessing actively psychotic schizophrenic patients. A second traditional assessment, the Clinical Global Impression (CGI), reflects the impression of a skilled observer, fully familiar with the manifestations of Schizohrenia, about the overall clinical state of the patient. In addition, 2 more recently developed scales were employed; these included the 30-item Positive and Negative Symptoms Scale (PANSS), in which are embedded the 18 items of the BPRS, and the Scale for Assessing Negative Symptoms (SANS). The trial summaries below focus on the following outcomes: PANSS total and/or BPRS total; BPRS psychosis cluster; PANSS negative subscale or SANS; and CGI Severity. The results of the trials follow:
    (1) In a 6 week, placebo-controlled trial (n = 149) involving 2 fixed olanzapine doses of 1 and 10 mg/day (once daily schedule), olanzapine, at 10 mg/day (but not at 1 mg/day), was superior to placebo on the PANSS total score (also on the extracted BPRS total), on the BPRS psychosis cluster, on the PANSS Negative subscale, and on CGI Severity.
    (2) In a 6 week, placebo-controlled trial (n = 253) involving 3 fixed dose ranges of olanzapine (5 (+/-)2.5 mg/day, 10 (+/-) 2.5 mg/day, and 15 (+/-) 2.5 mg/day) on a once daily schedule, the 2 highest olanzapine dose groups (actual man doses of 12 and 16 mg/day, respectively) were superior to placebo on BPRS total score, BPRS psychosis cluster, and CGI severity score; the highest olanzapine dose group was superior to placebo on the SANS. There was no clear advantage for the high-dose group over the medium-dose group.
    (3) In a longer-term trial, adult outpatients (n = 326) who predominantly met DSM-IV criteria for Schizophrenia and who remained stable on olanzapine during open-label treatment for at least 8 weeks were randomized to continuation on their current olanzapine doses (ranging from 10 to 20 mg/day) or to placebo. The follow-up period to observe patients for relapse, defined in terms of increases in BPRS positive symptoms or hospitalization, was planned for 12 months, however, criteria were met for stopping the trial early due to an excess of placebo relapses compared to olanzapine relapses, and olanzapine was superior to placebo on time to relapse, the primary outcome for this study. Thus, olanzapine was more effective than placebo at maintaining efficacy in patients stabilized for approximately 8 weeks and followed for an observation period of up to 8 months.
    Examination of population subsets (race and gender) did not reveal any differential responsiveness on the basis of these subgroupings.

    14.2 Bipolar I Disorder (Manic or Mixed Episodes)
    Adults
    Monotherapy
    The efficacy of oral olanzapine in the treatment of acute manic or mixed episodes was established in 2 short-term (one 3 week and one 4 week) placebo-controlled trials in adult patients who met the DSM-IV criteria for Bipolar I Disorder with manic or mixed episodes. These trials included patients with or without psychotic features and with or without a rapid-cycling course.
    The primary rating instrument used for assessing manic symptoms in these trials was the Young Mania Rating Scale (Y-MRS), an 11-item clinician-rated scale traditionally used to assess the degree of manic symptomatology (irritability, disruptive/aggressive behavior, sleep, elevated mood, speech, increased activity, sexual interest, language/thought disorder, thought content, appearance, and insight) in a range from 0 (no manic features) to 60 (maximum score). The primary outcome in these trials was change from baseline in the Y-MRS total score. The results of the trials follow:
    (1) In one 3 week placebo-controlled trial (n = 67) which involved a dose range of olanzapine (5 to 20 mg/day, once daily, starting at 10 mg/day), olanzapine was superior to placebo in the reduction of Y-MRS total score. In an identically designed trial conducted simultaneously with the first trial, olanzapine demonstrated a similar treatment difference, but possibly due to sample size and site variability, was not shown to be superior to placebo on this outcome.
    (2) In a 4 week placebo-controlled trial (n = 115) which involved a dose range of olanzapine (5 to 20 mg/day, once daily, starting at 15 mg/day), olanzapine was superior to placebo in the reduction of Y-MRS total score.
    (3) In another trial, 361 patients meeting DSM-IV criteria for a manic or mixed episode of Bipolar I Disorder who had responded during an initial open-label treatment phase for about 2 weeks, on average, to olanzapine 5 to 20 mg/day were randomized to either continuation of olanzapine at their same dose (n = 225) or to placebo (n = 136), for observation of relapse. Approximately 50% of the patients had discontinued from the olanzapine group by day 59 and 50% of the placebo group had discontinued by day 23 of double-blind treatment. Response during the open-label phase was defined by having a decrease of the Y-MRS total score to less than or equal to 12 and HAM-D 21 to less than or equal to 8. Relapse during the double-blind phase was defined as an increase of the Y-MRS or HAM-D 21 total score to greater than or equal to 15, or being hospitalized for either mania or depression. In the randomized phase, patients receiving continued olanzapine experienced a significantly longer time to relapse.
    Adjunct to Lithium or Valproate
    The efficacy of oral olanzapine with concomitant lithium or valproate in the treatment of acute manic or mixed episodes was established in 2 controlled trials in patients who met the DSM-IV criteria for Bipolar I Disorder with manic or mixed episodes. These trials included patients with or without psychotic features and with or without a rapid-cycling course. The results of the trials follow:
    (1) In one 6 week placebo-controlled combination trial, 175 outpatients on lithium or valproate therapy with inadequately controlled manic or mixed symptoms (Y-MRSgreater than or equal to 16) were randomized to receive either olanzapine or placebo, in combination with their original therapy. Olanzapine (in a dose range of 5 to 20 mg/day, once daily, starting at 10 mg/day) combined with lithium or valproate (in a therapeutic range of 0.6 mEq/L to 1.2 mEq/L or 50 ug per mL to 125 ug per mL, respectively) was superior to lithium or valproate alone in the reduction of Y-MRS total score.
    (2) In a second 6-week placebo-controlled combination trial, 169 outpatients on lithium or valproate therapy with inadequately controlled manic or mixed symptoms (Y-MRS greater than or equal to 16) were randomized to receive either olanzapine or placebo, in combination with their original therapy. Olanzapine (in a dose range of 5 to 20 mg/day, once daily, starting at 10 mg/day) combined with lithium or valproate (in a therapeutic range of 0.6 mEq/L to 1.2 mEq/L or 50 ug per mL to 125 ug per mL, respectively) was superior to lithium or valproate alone in the reduction of Y-MRS total score.

  • PATIENT COUNSELING INFORMATION

    See the FDA-approved Medication Guide for the oral formulations.
    Patients should be advised of the following issues and asked to alert their prescriber if these occur while taking olanzapine. If you do not think you are getting better or have any concerns about your condition while taking olanzapine, call your doctor. When using olanzapine and fluoxetine in combination, also refer to the Patient Counseling Information section of the package insert for olanzapine and fluoxetine in combination.

    17.1 Information on Medication Guide
    Prescribers or other health professionals should inform patients, their families, and their caregivers about the potential benefits and potential risks associated with treatment with olanzapine, and should counsel them in its appropriate use. A patient Medication Guide is available for olanzapine. Prescribers or other health professionals should instruct patients, their families, and their caregivers to read the Medication Guide and should assist them in understanding its contents. Patients should be given the opportunity to discuss the contents of the Medication Guide and to obtain answers to any questions they may have. When using olanzapine and fluoxetine in combination, also refer to the Medication Guide for olanzapine and fluoxetine in combination.

    17.2 Elderly Patients with Dementia-Related Psychosis: Increased Mortality and Cerebrovascular Adverse Events (CVAE), Including Stroke
    Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at increased risk of death. Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with olanzapine had a significantly higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) compared with placebo.
    Olanzapine is not approved for elderly patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions ( 5.1)].

    17.3 Neuroleptic Malignant Syndrome (NMS)
    Patients and caregivers should be counseled that a potentially fatal symptom complex sometimes referred to as NMS has been reported in association with administration of antipsychotic drugs, including olanzapine. Signs and symptoms of NMS include hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia) [see Warnings and Precautions ( 5.3)].

    17.4 Hyperglycemia
    Patients should be advised of the potential risk of hyperglycemia-related adverse reactions. Patients should be monitored regularly for worsening of glucose control. Patients who have diabetes should follow their doctorinstructions about how often to check their blood sugar while taking olanzapine [see Warnings and Precautions ( 5.4)].

    17.5 Hyperlipidemia
    Patients should be counseled that hyperlipidemia has occurred during treatment with olanzapine. Patients should have their lipid profile monitored regularly [see Warnings and Precautions ( 5.5)].

    17.6 Weight Gain
    Patients should be counseled that weight gain has occurred during treatment with olanzapine. Patients should have their weight monitored regularly [see Warnings and Precautions ( 5.6)].

    17.7 Orthostatic Hypotension
    Patients should be advised of the risk of orthostatic hypotension, especially during the period of initial dose titration and in association with the use of concomitant drugs that may potentiate the orthostatic effect of olanzapine, e.g., diazepam or alcohol [see Warnings and Precautions ( 5.8) and Drug Interactions (7)]. Patients should be advised to change positions carefully to help prevent orthostatic hypotension, and to lie down if they feel dizzy or faint, until they feel better. Patients should be advised to call their doctor if they experience any of the following signs and symptoms associated with orthostatic hypotension: dizziness, fast or slow heart beat, or fainting.

    17.8 Potential for Cognitive and Motor Impairment
    Because olanzapine has the potential to impair judgment, thinking, or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine therapy does not affect them adversely [see Warnings and Precautions ( 5.12)].

    17.9 Body Temperature Regulation
    Patients should be advised regarding appropriate care in avoiding overheating and dehydration. Patients should be advised to call their doctor right away if they become severely ill and have some or all of these symptoms of dehydration: sweating too much or not at all, dry mouth, feeling very hot, feeling thirsty, not able to produce urine [see Warnings and Precautions ( 5.13)].

    17.10 Concomitant Medication
    Patients should be advised to inform their physicians if they are taking, or plan to take, olanzapine and fluoxetine in combination. Patients should also be advised to inform their physicians if they are taking, plan to take, or have stopped taking any prescription or over-the-counter drugs, including herbal supplements, since there is a potential for interactions [see Drug Interactions ( 7)].

    17.11 Alcohol
    Patients should be advised to avoid alcohol while taking olanzapine [see Drug Interactions ( 7)].

Safety and effectiveness of olanzapine in patients under 13 years of age have not been established. Safety and effectiveness of olanzapine and fluoxetine in combination in patients < 18 years of age have not been established [see Warnings and Precautions ( 5.5,5.6) and Use in Specific Populations (8.4)].

  • Medication Guide

    Olanzapine Tablets USP
    Read the Medication Guide that comes with olanzapine before you start taking it and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your doctor about your medical condition or treatment. Talk with your doctor or pharmacist if there is something you do not understand or you want to learn more about olanzapine.
    What is the most important information I should know about olanzapine?
    Olanzapine may cause serious side effects, including:

    Your doctor should do tests to check your blood sugar before you start taking olanzapine and during treatment. In people who do not have diabetes, sometimes high blood sugar goes away when olanzapine is stopped. People with diabetes and some people who did not have diabetes before taking olanzapine need to take medicine for high blood sugar even after they stop taking olanzapine.

You may not have any symptoms, so your doctor should do blood tests to check your cholesterol and triglyceride levels before you start taking olanzapine and during treatment.
    4. Weight gain.Weight gain is very common in people who take olanzapine. Teenagers (13 to 17 years old) are more likely to gain weight and to gain more weight than adults. Some people may gain a lot of weight while taking olanzapine, so you and your doctor should check your weight regularly. Talk to your doctor about ways to control weight gain, such as eating a healthy, balanced diet, and exercising.
