CLINICAL PHARMACOLOGY SECTION
In a single and multiple dose absorption, distribution, metabolism, and excretion (ADME) study, using 3H labeled drug, temazepam was well absorbed and found to have minimal (8%) first pass metabolism. There were no active metabolites formed and the only significant metabolite present in blood was the O-conjugate. The unchanged drug was 96% bound to plasma proteins. The blood level decline of the parent drug was biphasic with the short half-life ranging from 0.4 - 0.6 hours and the terminal half-life from 3.5 - 18.4 hours (mean 8.8 hours), depending on the study population and method of determination. Metabolites were formed with a half-life of 10 hours and excreted with a half-life of approximately 2 hours. Thus, formation of the major metabolite is the rate limiting step in the biodisposition of temazepam. There is no accumulation of metabolites. A dose-proportional relationship has been established for the area under the plasma concentration/time curve over the 15 - 30 mg dose range.
Temazepam was completely metabolized through conjugation prior to excretion; 80% - 90% of the dose appeared in the urine. The major metabolite was the O-conjugate of temazepam (90%); the O-conjugate of N-desmethyl temazepam was a minor metabolite (7%).
Bioavailability, Induction, and Plasma Levels
Following ingestion of a 30 mg temazepam capsule, measurable plasma concentrations were achieved 10 - 20 minutes after dosing with peak plasma levels ranging from 666 - 982 ng/mL (mean 865 ng/mL) occurring approximately 1.2 - 1.6 hours (mean 1.5 hours) after dosing.
In a 7 day study, in which subjects were given a 30 mg temazepam capsule 1 hour before retiring, steady-state (as measured by the attainment of maximal trough concentrations) was achieved by the third dose. Mean plasma levels of temazepam (for days 2 to 7) were 260±210 ng/mL at 9 hours and 75±80 ng/mL at 24 hours after dosing. A slight trend toward declining 24-hour plasma levels was seen after day 4 in the study, however, the 24 hour plasma levels were quite variable.
At a dose of 30 mg once-a-day for 8 weeks, no evidence of enzyme induction was found in man.
Elimination Rate of Benzodiazepine Hypnotics and Profile of Common Untoward Effects
The type and duration of hypnotic effects and the profile of unwanted effects during administration of benzodiazepine hypnotics may be influenced by the biologic half-life of the administered drug and for some hypnotics, the half-life of any active metabolites formed. Benzodiazepine hypnotics have a spectrum of half-lives from short (<4 hours) to long (>20 hours). When half-lives are long, drug (and for some drugs their active metabolites) may accumulate during periods of nightly administration and be associated with impairments of cognitive and/or motor performance during waking hours; the possibility of interaction with other psychoactive drugs or alcohol will be enhanced. In contrast, if half-lives are shorter, drug (and, where appropriate, its active metabolites) will be cleared before the next dose is ingested, and carry-over effects related to excessive sedation or CNS depression should be minimal or absent. However, during nightly use for an extended period, pharmacodynamic tolerance or adaptation to some effects of benzodiazepine hypnotics may develop. If the drug has a short elimination half-life, it is possible that a relative deficiency of the drug, or, if appropriate, its active metabolites (i.e., in relationship to the receptor site) may occur at some point in the interval between each night’s use. This sequence of events may account for 2 clinical findings reported to occur after several weeks of nightly use of rapidly eliminated benzodiazepine hypnotics, namely, increased wakefulness during the last third of the night, and the appearance of increased signs of daytime anxiety.
Controlled Trials Supporting Efficacy: Temazepam improved sleep parameters in clinical studies. Residual medication effects (“hangover”) were essentially absent. Early morning awakening, a particular problem in the geriatric patient, was significantly reduced.
Patients with chronic insomnia were evaluated in 2 week, placebo controlled sleep laboratory studies with temazepam at doses of 7.5 mg, 15 mg, and 30 mg, given 30 minutes prior to bedtime. There was a linear dose-response improvement in total sleep time and sleep latency, with significant drug-placebo differences at 2 weeks occurring only for total sleep time at the 2 higher doses, and for sleep latency only at the highest dose.
In these sleep laboratory studies, REM sleep was essentially unchanged and slow wave sleep was decreased. No measurable effects on daytime alertness or performance occurred following temazepam treatment or during the withdrawal period, even though a transient sleep disturbance in some sleep parameters was observed following withdrawal of the higher doses. There was no evidence of tolerance development in the sleep laboratory parameters when patients were given temazepam nightly for at least 2 weeks.
In addition, normal subjects with transient insomnia associated with first night adaptation to the sleep laboratory were evaluated in 24 hour, placebo controlled sleep laboratory studies with temazepam at doses of 7.5 mg, 15 mg, and 30 mg, given 30 minutes prior to bedtime. There was a linear dose-response improvement in total sleep time, sleep latency and number of awakenings, with significant drug-placebo differences occurring for sleep latency at all doses, for total sleep time at the 2 higher doses and for number of awakenings only at the 30 mg dose.
INDICATIONS & USAGE SECTION
Temazepam is indicated for the short-term treatment of insomnia (generally 7 - 10 days).
For patients with short-term insomnia, instructions in the prescription should indicate that temazepam should be used for short periods of time (7 - 10 days).
The clinical trials performed in support of efficacy were 2 weeks in duration with the final formal assessment of sleep latency performed at the end of treatment.
Benzodiazepines may cause fetal harm when administered to a pregnant woman. An increased risk of congenital malformations associated with the use of diazepam and chlordiazepoxide during the first trimester of pregnancy has been suggested in several studies. Transplacental distribution has resulted in neonatal CNS depression following the ingestion of therapeutic doses of a benzodiazepine hypnotic during the last weeks of pregnancy.
Reproduction studies in animals with temazepam were performed in rats and rabbits. In a perinatal-postnatal study in rats, oral doses of 60 mg/kg/day resulted in increasing nursling mortality. Teratology studies in rats demonstrated increased fetal resorptions at doses of 30 and 120 mg/kg in one study and increased occurrence of rudimentary ribs, which are considered skeletal variants, in a second study at doses of 240 mg/kg or higher. In rabbits, occasional abnormalities such as exencephaly and fusion or asymmetry of ribs were reported without dose relationship. Although these abnormalities were not found in the concurrent control group, they have been reported to occur randomly in historical controls. At doses of 40 mg/kg or higher, there was an increased incidence of the 13th rib variant when compared to the incidence in concurrent and historical controls.
Temazepam is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Patients should be instructed to discontinue the drug prior to becoming pregnant. The possibility that a woman of childbearing potential may be pregnant at the time of institution of therapy should be considered.
Since the risk of the development of oversedation, dizziness, confusion, and/or ataxia increases substantially with larger doses of benzodiazepines in elderly and debilitated patients, 7.5 mg of temazepam is recommended as the initial dosage for such patients.
Temazepam should be administered with caution in severely depressed patients or those in whom there is any evidence of latent depression; it should be recognized that suicidal tendencies may be present and protective measures may be necessary.
The usual precautions should be observed in patients with impaired renal or hepatic function and in patients with chronic pulmonary insufficiency.
If temazepam is to be combined with other drugs having known hypnotic properties or CNS-depressant effects, consideration should be given to potential additive effects.
The possibility of a synergistic effect exists with the co-administration of temazepam and diphenhydramine. One case of stillbirth at term has been reported 8 hours after a pregnant patient received temazepam and diphenhydramine. A cause and effect relationship has not yet been determined (see CONTRAINDICATIONS).
Information for Patients
The text of a patient Medication Guide is printed at the end of this insert. To assure safe and effective use of temazepam, the information and instructions provided in this patient Medication Guide should be discussed with patients.
“Sleep-Driving” and Other Complex Behaviors – There have been reports of people getting out of bed after taking a sedative-hypnotic and driving their cars while not fully awake, often with no memory of the event. If a patient experiences such an episode, it should be reported to his or her doctor immediately, since “sleep-driving” can be dangerous. This behavior is more likely to occur when temazepam is taken with alcohol or other central nervous system depressants (see WARNINGS). Other complex behaviors (e.g., preparing and eating food, making phone calls, or having sex) have been reported in patients who are not fully awake after taking a sedative-hypnotic. As with sleep-driving, patients usually do not remember these events.
The usual precautions should be observed in patients with impaired renal or hepatic function and in patients with chronic pulmonary insufficiency. Abnormal liver function tests as well as blood dyscrasias have been reported with benzodiazepines.
The pharmacokinetic profile of temazepam does not appear to be altered by orally administered cimetidine dosed according to labeling.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenicity studies were conducted in rats at dietary temazepam doses up to 160 mg/kg/day for 24 months and in mice at dietary doses of 160 mg/kg/day for 18 months. No evidence of carcinogenicity was observed although hyperplastic liver nodules were observed in female mice exposed to the highest dose. The clinical significance of this finding is not known.
Fertility in male and female rats was not adversely affected by temazepam.
No mutagenicity tests have been done with temazepam.
Pregnancy Category X (see CONTRAINDICATIONS).
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when temazepam is administered to a nursing woman.
Safety and effectiveness in pediatric patients have not been established.
ADVERSE REACTIONS SECTION
During controlled clinical studies in which 1076 patients received temazepam at bedtime, the drug was well tolerated. Side effects were usually mild and transient. Adverse reactions occurring in 1% or more of patients are presented in the following table:
Temazepam Placebo % Incidence
Drowsiness 9.1 5.6 Headache 8.5 9.1 Fatigue 4.8 4.7 Nervousness 4.6 8.2 Lethargy 4.5 3.4 Dizziness 4.5 3.3 Nausea 3.1 3.8 Hangover 2.5 1.1 Anxiety 2.0 1.5 Depression 1.7 1.8 Dry Mouth 1.7 2.2 Diarrhea 1.7 1.1 Abdominal Discomfort 1.5 1.9 Euphoria 1.5 0.4 Weakness 1.4 0.9 Confusion 1.3 0.5 Blurred Vision 1.3 1.3 Nightmares 1.2 1.7 Vertigo 1.2 0.8
The following adverse events have been reported less frequently (0.5% - 0.9%):
Central Nervous System – anorexia, ataxia, equilibrium loss, tremor, increased dreaming
Cardiovascular – dyspnea, palpitations
Gastrointestinal – vomiting
Musculoskeletal – backache
Special Senses – hyperhidrosis, burning eyes
Amnesia, hallucinations, horizontal nystagmus, and paradoxical reactions including restlessness, overstimulation and agitation were rare (less than 0.5%).
DRUG ABUSE AND DEPENDENCE SECTION
Abuse and addiction are separate and distinct from physical dependence and tolerance. Abuse is characterized by misuse of the drug for non-medical purposes, often in combination with other psychoactive substances. Physical dependence is a state of adaptation that is manifested by a specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug and/or administration of an antagonist. Tolerance is a state of adaptation in which exposure to a drug induces changes that result in a diminution of one or more of the drug’s effects over time. Tolerance may occur to both the desired and undesired effects of drugs and may develop at different rates for different effects.
Addiction is a primary, chronic, neurobiological disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. It is characterized by behaviors that include one or more of the following: impaired control over drug use, compulsive use, continued use despite harm, and craving. Drug addiction is a treatable disease, utilizing a multidisciplinary approach, but relapse is common.
Temazepam is a controlled substance in Schedule IV.
Abuse and Dependence
Withdrawal symptoms, similar in character to those noted with barbiturates and alcohol (convulsions, tremor, abdominal, and muscle cramps, vomiting, and sweating), have occurred following abrupt discontinuance of benzodiazepines. The more severe withdrawal symptoms have usually been limited to those patients who received excessive doses over an extended period of time. Generally milder withdrawal symptoms (e.g., dysphoria and insomnia) have been reported following abrupt discontinuance of benzodiazepines taken continuously at therapeutic levels for several months. Consequently, after extended therapy at doses higher than 15 mg, abrupt discontinuation should generally be avoided and a gradual dosage tapering schedule followed. As with any hypnotic, caution must be exercised in administering temazepam to individuals known to be addiction-prone or to those whose history suggests they may increase the dosage on their own initiative. It is desirable to limit repeated prescriptions without adequate medical supervision.
Manifestations of acute overdosage of temazepam can be expected to reflect the CNS effects of the drug and include somnolence, confusion, and coma, with reduced or absent reflexes, respiratory depression, and hypotension. The oral LD50 of temazepam was 1963 mg/kg in mice, 1833 mg/kg in rats, and >2400 mg/kg in rabbits.
If the patient is conscious, vomiting should be induced mechanically or with emetics. Gastric lavage should be employed utilizing concurrently a cuffed endotracheal tube if the patient is unconscious to prevent aspiration and pulmonary complications. Maintenance of adequate pulmonary ventilation is essential. The use of pressor agents intravenously may be necessary to combat hypotension. Fluids should be administered intravenously to encourage diuresis. The value of dialysis has not been determined. If excitation occurs, barbiturates should not be used. It should be borne in mind that multiple agents may have been ingested. Flumazenil, a specific benzodiazepine receptor antagonist, is indicated for the complete or partial reversal of the sedative effects of benzodiazepines and may be used in situations when an overdose with a benzodiazepine is known or suspected. Prior to the administration of flumazenil, necessary measures should be instituted to secure airway, ventilation, and intravenous access. Flumazenil is intended as an adjunct to, not as a substitute for, proper management of benzodiazepine overdose. Patients treated with flumazenil should be monitored for re-sedation, respiratory depression, and other residual benzodiazepine effects for an appropriate period after treatment. The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users and in cyclic antidepressant overdose. The complete flumazenil package insert including CONTRAINDICATIONS, WARNINGS, and PRECAUTIONS should be consulted prior to use.
Up-to-date information about the treatment of overdose can often be obtained from a certified Regional Poison Control Center. Telephone numbers of certified Regional Poison Control Centers are listed in the Physicians’ Desk Reference.
DOSAGE & ADMINISTRATION SECTION
While the recommended usual adult dose is 15 mg before retiring, 7.5 mg may be sufficient for some patients, and others may need 30 mg. In transient insomnia, a 7.5 mg dose may be sufficient to improve sleep latency. In elderly or debilitated patients, it is recommended that therapy be initiated with 7.5 mg until individual responses are determined.

What is the most important information I should know about temazepam?
After taking temazepam, you may get up out of bed while not being fully awake and do an activity that you do not know you are doing. The next morning, you may not remember that you did anything during the night. You have a higher chance for doing these activities if you drink alcohol or take other medicines that make you sleepy with temazepam. Reported activities include:
• driving a car (“sleep-driving”)
• making and eating food
• talking on the phone
• having sex
Call your doctor right away if you find out that you have done any of the above activities after taking temazepam.
1. Take temazepam exactly as prescribed
• Do not take more temazepam than prescribed.
• Take temazepam right before you get in bed, not sooner.
2. Do not take temazepam if you:
• drink alcohol
• take other medicines that can make you sleepy. Talk to your doctor about all of your medicines. Your doctor will tell you if you can take temazepam with your other medicines
• cannot get a full night’s sleep
What is temazepam?
Temazepam is a sedative-hypnotic (sleep) medicine. Temazepam is used in adults for the short-term (usually 7 to 10 days) treatment of a sleep problem called insomnia. Symptoms of insomnia include:
• trouble falling asleep
• waking up often during the night
Temazepam is not for children.
Temazepam is a federally controlled substance (C-IV) because it can be abused or lead to dependence. Keep temazepam in a safe place to prevent misuse and abuse. Selling or giving away temazepam may harm others, and is against the law. Tell your doctor if you have ever abused or been dependent on alcohol, prescription medicines or street drugs.
Who should not take temazepam?
Do not take temazepam if you are pregnant or planning to become pregnant. Temazepam may cause birth defects or harm a fetus (unborn baby).
Temazepam may not be right for you. Before starting temazepam, tell your doctor about all of your health conditions, including if you:
• have a history of depression, mental illness, or suicidal thoughts
• have a history of drug or alcohol abuse or addiction
• have kidney or liver disease
• have a lung disease or breathing problems
• are breastfeeding
Tell your doctor about all of the medicines you take including prescription and nonprescription medicines, vitamins and herbal supplements. Medicines can interact with each other, sometimes causing serious side effects. Do not take temazepam with other medicines that can make you sleepy.
Know the medicines you take. Keep a list of your medicines with you to show your doctor and pharmacist each time you get a new medicine.
How should I take temazepam?
• Take temazepam exactly as prescribed. Do not take more temazepam than prescribed for you.
• Take temazepam right before you get into bed.
• Do not take temazepam unless you are able to get a full night’s sleep before you must be active again.
• Call your doctor if your insomnia worsens or is not better within 7 to 10 days. This may mean that there is another condition causing your sleep problems.
• If you take too much temazepam or overdose, call your doctor or poison control center right away, or get emergency treatment.
What are the possible side effects of temazepam?
Possible serious side effects of temazepam include:
• getting out of bed while not being fully awake and do an activity that you do not know you are doing. (See “What is the most important information I should know about temazepam?”)
• abnormal thoughts and behavior. Symptoms include more outgoing or aggressive behavior than normal, confusion, agitation, hallucinations, worsening of depression, and suicidal thoughts.
• memory loss
• severe allergic reactions. Symptoms include swelling of the tongue or throat, trouble breathing, and nausea and vomiting. Get emergency medical help if you get these symptoms after taking temazepam.
Call your doctor right away if you have any of the above side effects or any other side effects that worry you while using temazepam.
The most common side effects of temazepam are:
• “hangover” feeling the day after taking temazepam
• You may still feel drowsy the next day after taking temazepam. Do not drive or do other dangerous activities after taking temazepam until you feel fully awake.
• You may have withdrawal symptoms if you stop taking temazepam suddenly. Withdrawal symptoms can be serious and include seizures. Mild withdrawal symptoms include a depressed mood and trouble sleeping. Talk to your doctor to check if you need to stop temazepam slowly.
These are not all the side effects of temazepam. Ask your doctor or pharmacist for more information.
How should I store temazepam?
• Store temazepam at room temperature, 68° to 77°F (20° to 25°C).
• Keep temazepam and all medicines out of reach of children.
General Information about temazepam
• Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide.
• Do not use temazepam for a condition for which it was not prescribed.
• Do not share temazepam with other people, even if you think they have the same symptoms that you have. It may harm them and it is against the law.
This Medication Guide summarizes the most important information about temazepam. If you would like more information, talk with your doctor. You can ask your doctor or pharmacist for information about temazepam that is written for healthcare professionals.
