Central Nervous Sys tem
Oxycodone is a semisynthetic pure opioid agonist whose principal therapeutic action is analgesia.
Other pharmacological effects of oxycodone include anxiolysis, euphoria and feelings of relaxation.
These effects are mediated by receptors (notably µ and ?) in the central nervous system for endogenous
opioid-like compounds such as endorphins and enkephalins. Oxycodone produces respiratory
depression through direct activity at respiratory centers in the brain stem and depresses the cough
reflex by direct effect on the center of the medulla.
Acetaminophen is a non-opiate, non-salicylate analgesic and antipyretic. The site and mechanism for the
analgesic effect of acetaminophen has not been determined. The antipyretic effect of acetaminophen is
accomplished through the inhibition of endogenous pyrogen action on the hypothalamic heat-regulating
centers.
Gas trointes tinal Tract and Other Smooth Mus cle
Oxycodone reduces motility by increasing smooth muscle tone in the stomach and duodenum. In the
small intestine, digestion of food is delayed by decreases in propulsive contractions. Other opioid
effects include contraction of biliary tract smooth muscle, spasm of the Sphincter of Oddi, increased
ureteral and bladder sphincter tone, and a reduction in uterine tone.
Cardiovas cular Sys tem
Oxycodone may produce a release of histamine and may be associated with orthostatic hypotension and
other symptoms, such as pruritus, flushing, red eyes and sweating.

Absorption and Distribution
The mean absolute oral bioavailability of oxycodone in cancer patients was reported to be about 87%.
Oxycodone has been shown to be 45% bound to human plasma proteins in vitro. The volume of
distribution after intravenous administration is 211.9 ±186.6 L.
Absorption of acetaminophen is rapid and almost complete from the GI tract after oral administration.
With overdosage, absorption is complete in 4 hours. Acetaminophen is relatively uniformly distributed
throughout most body fluids. Binding of the drug to plasma proteins is variable; only 20% to 50% may
be bound at the concentrations encountered during acute intoxication.
Metabolis m and Elimination
A high portion of oxycodone is N-dealkylated to noroxycodone during first-pass metabolism.
Oxymorphone, is formed by the O-demethylation of oxycodone. The metabolism of oxycodone to
oxymorphone is catalyzed by CYP2D6. Free and conjugated noroxycodone, free and conjugated
oxycodone, and oxymorphone are excreted in human urine following a single oral dose of oxycodone.
Approximately 8% to 14% of the dose is excreted as free oxycodone over 24 hours after
administration. Following a single, oral dose of oxycodone, the mean ± SD elimination half-life is 3.51
± 1.43 hours.
Acetaminophen is metabolized in the liver via cytochrome P450 microsomal enzyme. About 80% to
85% of the acetaminophen in the body is conjugated principally with glucuronic acid and to a lesser
extent with sulfuric acid and cysteine. After hepatic conjugation, 90% to 100% of the drug is recovered
in the urine within the first day.
About 4% of acetaminophen is metabolized via cytochrome P450 oxidase to a toxic metabolite which is
further detoxified by conjugation with glutathione, present in a fixed amount. It is believed that the toxic
metabolite NAPQI (N acetyl-p-benzoquinoneimine, N-acetylimidoquinone) is responsible for liver
necrosis. High doses of acetaminophen may deplete the glutathione stores so that inactivation of the
toxic metabolite is decreased. At high doses, the capacity of metabolic pathways for conjugation with
glucuronic acid and sulfuric acid may be exceeded, resulting in increased metabolism of acetaminophen
by alternate pathways.

Oxycodone and acetaminophen tablets, USP are indicated for the relief of moderate to moderately
severe pain.

Oxycodone and acetaminophen tablets, USP should not be administered to patients with known
hypersensitivity to oxycodone, acetaminophen, USP, or any other component of this product.
Oxycodone is contraindicated in any situation where opioids are contraindicated including patients with
significant respiratory depression (in unmonitored settings or the absence of resuscitative equipment)
and patients with acute or severe bronchial asthma or hypercarbia. Oxycodone is contraindicated in the
setting of suspected or known paralytic ileus.

Hepatotoxicity
Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver
transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at
doses that exceed 4000 milligrams per day, and often involve more than one acetaminophen-containing
product. The excessive intake of acetaminophen may be intentional to cause self-harm or unintentional
as patients attempt to obtain more pain relief or unknowingly take other acetaminophen-containing
products.
The risk of acute liver failure is higher in individuals with underlying liver disease and in individuals
who ingest alcohol while taking acetaminophen.
Instruct patients to look for acetaminophen or APAP on package labels and not to use more than one
product that contains acetaminophen. Instruct patients to seek medical attention immediately upon
ingestion of more than 4000 milligrams of acetaminophen per day, even if they feel well.
Serious s kin reactions
Rarely, acetaminophen may cause serious skin reactions such as acute generalized exanthematous
pustulosis (AGEP), Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can
be fatal. Patients should be informed about the signs of serious skin reactions, and use of the drug
should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity.
Hypers ens itivity/ anaphylaxis
There have been post-marketing reports of hypersensitivity and anaphylaxis associated with use of
acetaminophen. Clinical signs include swelling of the face, mouth, and throat, respiratory distress,
urticaria, rash, pruritis, and vomiting. There were infrequent reports of life-threatening anaphylaxis
requiring emergency medical attention. Instruct patients to discontinue Oxycodone and Acetaminophen
Tablets, USP immediately and seek medical care if they experience these symptoms. Do not prescribe
Oxycodone and Acetaminophen Tablets, USP for patients with acetaminophen allergy.
Mis us e, Abus e and Divers ion of Opioids
Oxycodone is an opioid agonist of the morphine-type. Such drugs are sought by drug abusers and
people with addiction disorders and are subject to criminal diversion.
Oxycodone can be abused in a manner similar to other opioid agonists, legal or illicit. This should be
considered when prescribing or dispensing oxycodone and acetaminophen tablets in situations where
the physician or pharmacist is concerned about an increased risk of misuse, abuse, or diversion.
Concerns about misuse, addiction and diversion should not prevent the proper management of pain.
Healthcare professionals should contact their State Professional Licensing Board or State Controlled
Substances Authority for information on how to prevent and detect abuse or diversion of this product.
Administration of oxycodone and acetaminophen tablets should be closely monitored for the following
potentially serious adverse reactions and complications:
Res piratory Depres s ion
Respiratory depression is a hazard with the use of oxycodone, one of the active ingredients in
oxycodone and acetaminophen tablets, as with all opioid agonists. Elderly and debilitated patients are at
particular risk for respiratory depression as are non-tolerant patients given large initial doses of
oxycodone or when oxycodone is given in conjunction with other agents that depress respiration.
Oxycodone should be used with extreme caution in patients with acute asthma, chronic obstructive
pulmonary disorder (COPD), cor pulmonale, or preexisting respiratory impairment. In such patients,
even usual therapeutic doses of oxycodone may decrease respiratory drive to the point of apnea. In
these patients alternative non-opioid analgesics should be considered, and opioids should be employed
only under careful medical supervision at the lowest effective dose.
In case of respiratory depression, a reversal agent such as naloxone hydrochloride may be utilized (see

Head Injury and Increas ed Intracranial Pres s ure
The respiratory depressant effects of opioids include carbon dioxide retention and secondary elevation
of cerebrospinal fluid pressure, and may be markedly exaggerated in the presence of head injury, other
intracranial lesions or a preexisting increase in intracranial pressure. Oxycodone produces effects on
pupillary response and consciousness which may obscure neurologic signs of worsening in patients
with head injuries.
Hypotens ive Effect
Oxycodone may cause severe hypotension particularly in individuals whose ability to maintain blood
pressure has been compromised by a depleted blood volume, or after concurrent administration with
drugs which compromise vasomotor tone such as phenothiazines. Oxycodone, like all opioid analgesics
of the morphine-type, should be administered with caution to patients in circulatory shock, since
vasodilation produced by the drug may further reduce cardiac output and blood pressure. Oxycodone
may produce orthostatic hypotension in ambulatory patients.
Hepatotoxicity
Precaution should be taken in patients with liver disease. Hepatotoxicity and severe hepatic failure
occurred in chronic alcoholics following therapeutic doses.

General
Opioid analgesics should be used with caution when combined with CNS depressant drugs, and should
be reserved for cases where the benefits of opioid analgesia outweigh the known risks of respiratory
depression, altered mental state and postural hypotension.
Acute Abdominal Conditions
The administration of oxycodone and acetaminophen tablets or other opioids may obscure the diagnosis
or clinical course in patients with acute abdominal conditions.
Oxycodone and acetaminophen tablets should be given with caution to patients with CNS depression,
elderly or debilitated patients, patients with severe impairment of hepatic, pulmonary, or renal function,
hypothyroidism, Addison's disease, prostatic hypertrophy, urethral stricture, acute alcoholism, delirium
tremens, kyphoscoliosis with respiratory depression, myxedema and toxic psychosis.
Oxycodone and acetaminophen tablets may obscure the diagnosis or clinical course in patients with
acute abdominal conditions. Oxycodone may aggravate convulsions in patients with convulsive
disorders, and all opioids may induce or aggravate seizures in some clinical settings.
Following administration of oxycodone and acetaminophen tablets, anaphylactic reactions have been
reported in patients with a known hypersensitivity to codeine, a compound with a structure similar to
morphine and oxycodone. The frequency of this possible cross-sensitivity is unknown.
Interactions with Other CNS Depres s ants
Patients receiving other opioid analgesics, general anesthetics, phenothiazines, other tranquilizers,
centrally-acting antiemetics, sedative-hypnotics or other CNS depressants (including alcohol)
concomitantly with oxycodone and acetaminophen tablets may exhibit an additive CNS depression. When
such combined therapy is contemplated, the dose of one or both agents should be reduced.
Interactions with Mixed Agonis t/Antagonis t Opioid Analges ics
Agonist/antagonist analgesics (i.e., pentazocine, nalbuphine and butorphanol) should be administered
with caution to a patient who has received or is receiving a course of therapy with a pure opioid
agonist analgesic such as oxycodone. In this situation, mixed agonist/antagonist analgesics may reduce
the analgesic effect of oxycodone and/or may precipitate withdrawal symptoms in these patients.
Ambulatory Surgery and Pos toperative Us e
Oxycodone and other morphine-like opioids have been shown to decrease bowel motility. Ileus is a
common postoperative complication, especially after intraabdominal surgery with use of opioid
analgesia. Caution should be taken to monitor for decreased bowel motility in postoperative patients
receiving opioids. Standard supportive therapy should be implemented.
Us e in Pancreatic/Biliary Tract Dis eas e
Oxycodone may cause spasm of the Sphincter of Oddi and should be used with caution in patients with
biliary tract disease, including acute pancreatitis. Opioids like oxycodone may cause increases in the
serum amylase level.
Tolerance and Phys ical Dependence
Tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (in
the absence of disease progression or other external factors). Physical dependence is manifested by
withdrawal symptoms after abrupt discontinuation of a drug or upon administration of an antagonist.
Physical dependence and tolerance are not unusual during chronic opioid therapy.
The opioid abstinence or withdrawal syndrome is characterized by some or all of the following:
restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia and mydriasis. Other
symptoms also may develop, including: irritability, anxiety, backache, joint pain, weakness, abdominal
cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or
heart rate.
In general, opioids should not be abruptly discontinued (see DOSAGE AND ADMINISTRATION:
Ces s ation of Therapy).
Information for Patients /Caregivers
The following information should be provided to patients receiving oxycodone and acetaminophen tablets by
their physician, nurse, pharmacist, or caregiver:
Do not take oxycodone and acetaminophen tablets if you are allergic to any of its ingredients.
If you develop signs of allergy such as a rash or difficulty breathing, stop taking oxycodone and
acetaminophen and contact your healthcare provider immediately.
Do not take more than 4,000 milligrams of acetaminophen per day. Call your doctor if you took
more than the recommended dose.
1. Patients should be aware that oxycodone and acetaminophen tablets contain oxycodone, which is a
morphine-like substance.
2. Patients should be instructed to keep oxycodone and acetaminophen tablets in a secure place out of
the reach of children. In the case of accidental ingestions, emergency medical care should be sought
immediately.
3. When oxycodone and acetaminophen tablets are no longer needed, the unused tablets should be
destroyed by flushing down the toilet.
4. Patients should be advised not to adjust the medication dose themselves. Instead, they must consult
with their prescribing physician.
5. Patients should be advised that oxycodone and acetaminophen tablets may impair mental and/or
physical ability required for the performance of potentially hazardous tasks (e.g., driving, operating
heavy machinery).
6. Patients should not combine oxycodone and acetaminophen tablets with alcohol, opioid analgesics,
tranquilizers, sedatives, or other CNS depressants unless under the recommendation and guidance of
a physician. When co-administered with another CNS depressant, oxycodone and acetaminophen
tablets can cause dangerous additive central nervous system or respiratory depression, which can
result in serious injury or death.
7. The safe use of oxycodone and acetaminophen tablets during pregnancy has not been established;
thus, women who are planning to become pregnant or are pregnant should consult with their
physician before taking oxycodone and acetaminophen tablets.
8. Nursing mothers should consult with their physicians about whether to discontinue nursing or
discontinue oxycodone and acetaminophen tablets because of the potential for serious adverse
reactions to nursing infants.
9. Patients who are treated with oxycodone and acetaminophen tablets for more than a few weeks
should be advised not to abruptly discontinue the medication. Patients should consult with their
physician for a gradual discontinuation dose schedule to taper off the medication.
10. Patients should be advised that oxycodone and acetaminophen tablets are a potential drug of abuse.
They should protect it from theft, and it should never be given to anyone other than the individual for
whom it was prescribed.

Although oxycodone may cross-react with some drug urine tests, no available studies were found
which determined the duration of detectability of oxycodone in urine drug screens. However, based on
pharmacokinetic data, the approximate duration of detectability for a single dose of oxycodone is
roughly estimated to be one to two days following drug exposure.
Urine testing for opiates may be performed to determine illicit drug use and for medical reasons such as
evaluation of patients with altered states of consciousness or monitoring efficacy of drug rehabilitation
efforts. The preliminary identification of opiates in urine involves the use of an immunoassay screening
and thin-layer chromatography (TLC). Gas chromatography/mass spectrometry (GC/MS) may be utilized
as a third-stage identification step in the medical investigational sequence for opiate testing after
immunoassay and TLC. The identities of 6-keto opiates (e.g., oxycodone) can further be differentiated
by the analysis of their methoxime-trimethylsilyl (MO-TMS) derivative.

Opioid analgesics may enhance the neuromuscular-blocking action of skeletal muscle relaxants and
produce an increase in the degree of respiratory depression.
Patients receiving CNS depressants such as other opioid analgesics, general anesthetics,
phenothiazines, other tranquilizers, centrally-acting anti-emetics, sedative-hypnotics or other CNS
depressants (including alcohol) concomitantly with oxycodone and acetaminophen tablets may exhibit an
additive CNS depression. When such combined therapy is contemplated, the dose of one or both agents
should be reduced. The concurrent use of anticholinergics with opioids may produce paralytic ileus.
Agonist/antagonist analgesics (i.e., pentazocine, nalbuphine, naltrexone and butorphanol) should be
administered with caution to a patient who has received or is receiving a pure opioid agonist such as
oxycodone. These agonist/antagonist analgesics may reduce the analgesic effect of oxycodone or may
precipitate withdrawal symptoms.
Drug/Drug Interactions with Acetaminophen
Alcohol, ethyl: Hepatotoxicity has occurred in chronic alcoholics following various dose levels
(moderate to excessive) of acetaminophen.
Anticholinergics: The onset of acetaminophen effect may be delayed or decreased slightly, but the
ultimate pharmacological effect is not significantly affected by anticholinergics.
Oral Contraceptives: Increase in glucuronidation resulting in increased plasma clearance and a
decreased half-life of acetaminophen.
Charcoal (activated): Reduces acetaminophen absorption when administered as soon as possible after
overdose.
Beta-Blockers (Propranolol): Propranolol appears to inhibit the enzyme systems responsible for the
glucuronidation and oxidation of acetaminophen. Therefore, the pharmacologic effects of
acetaminophen may be increased.
Loop diuretics: The effects of the loop diuretic may be decreased because acetaminophen may
decrease renal prostaglandin excretion and decrease plasma renin activity.
Lamotrigine: Serum lamotrigine concentrations may be reduced, producing a decrease in therapeutic
effects.
Probenecid: Probenecid may increase the therapeutic effectiveness of acetaminophen slightly.
Zidovudine: The pharmacologic effects of zidovudine may be decreased because of enhanced nonhepatic
or renal clearance of zidovudine.
Drug/Laboratory Tes t Interactions
Depending on the sensitivity/specificity and the test methodology, the individual components of
oxycodone and acetaminophen tablets may cross-react with assays used in the preliminary detection of
cocaine (primary urinary metabolite, benzoylecgonine) or marijuana (cannabinoids) in human urine. A
more specific alternate chemical method must be used in order to obtain a confirmed analytical result.
The preferred confirmatory method is gas chromatography/mass spectrometry (GC/MS). Moreover,
clinical considerations and professional judgment should be applied to any drug-of-abuse test result,
particularly when preliminary positive results are used.
Acetaminophen may interfere with home blood glucose measurement systems; decreases of >20% in
mean glucose values may be noted. This effect appears to be drug, concentration and system dependent.
Carcinogenes is , Mutagenes is , Impairment of Fertility
Carcinogenesis
Animal studies to evaluate the carcinogenic potential of oxycodone and acetaminophen have not been
performed.
Mutagenesis
The combination of oxycodone and acetaminophen has not been evaluated for mutagenicity. Oxycodone
alone was negative in a bacterial reverse mutation assay (Ames), an in vitro chromosome aberration
assay with human lymphocytes without metabolic activation and an in vivo mouse micronucleus assay.
Oxycodone was clastogenic in the human lymphocyte chromosomal assay in the presence of metabolic
activation and in the mouse lymphoma assay with or without metabolic activation.
Fertility
Animal studies to evaluate the effects of oxycodone on fertility have not been performed.
Pregnancy
Teratogenic Effects
Pregnancy Category C
Animal reproductive studies have not been conducted with oxycodone and acetaminophen. It is also not
known whether oxycodone and acetaminophen can cause fetal harm when administered to a pregnant
woman or can affect reproductive capacity. Oxycodone and acetaminophen should not be given to a
pregnant woman unless in the judgment of the physician, the potential benefits outweigh the possible
hazards.
Nonteratogenic Effects
Opioids can cross the placental barrier and have the potential to cause neonatal respiratory depression.
Opioid use during pregnancy may result in a physically drug-dependent fetus. After birth, the neonate
may suffer severe withdrawal symptoms.
Labor and Delivery
Oxycodone and acetaminophen tablets are not recommended for use in women during and immediately
prior to labor and delivery due to its potential effects on respiratory function in the newborn.
Nurs ing Mothers
Ordinarily, nursing should not be undertaken while a patient is receiving oxycodone and acetaminophen
tablets because of the possibility of sedation and/or respiratory depression in the infant. Oxycodone is
excreted in breast milk in low concentrations, and there have been rare reports of somnolence and
lethargy in babies of nursing mothers taking an oxycodone/acetaminophen product. Acetaminophen is
also excreted in breast milk in low concentrations.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established.
Geriatric Use
Special precaution should be given when determining the dosing amount and frequency of oxycodone
and acetaminophen tablets for geriatric patients, since clearance of oxycodone may be slightly reduced
in this patient population when compared to younger patients.
Hepatic Impairment
In a pharmacokinetic study of oxycodone in patients with end-stage liver disease, oxycodone plasma
clearance decreased and the elimination half-life increased. Care should be exercised when oxycodone
is used in patients with hepatic impairment.
Renal Impairment
In a study of patients with end stage renal impairment, mean elimination half-life was prolonged in
uremic patients due to increased volume of distribution and reduced clearance. Oxycodone should be
used with caution in patients with renal impairment.

Serious adverse reactions that may be associated with oxycodone and acetaminophen tablet use include
respiratory depression, apnea, respiratory arrest, circulatory depression, hypotension and shock (see
OVERDOSAGE).
The most frequently observed non-serious adverse reactions include lightheadedness, dizziness,
drowsiness or sedation, nausea and vomiting. These effects seem to be more prominent in ambulatory
than in nonambulatory patients, and some of these adverse reactions may be alleviated if the patient lies
down. Other adverse reactions include euphoria, dysphoria, constipation and pruritus.
Hypersensitivity reactions may include: Skin eruptions, urticarial, erythematous skin reactions.
Hematologic reactions may include: Thrombocytopenia, neutropenia, pancytopenia, hemolytic anemia.
Rare cases of agranulocytosis has likewise been associated with acetaminophen use. In high doses, the
most serious adverse effect is a dose-dependent, potentially fatal hepatic necrosis. Renal tubular
necrosis and hypoglycemic coma also may occur.
Other adverse reactions obtained from postmarketing experiences with oxycodone and acetaminophen
tablets are listed by organ system and in decreasing order of severity and/or frequency as follows:

Oxycodone and acetaminophen tablets are a Schedule II controlled substance. Oxycodone is a muagonist
opioid with an abuse liability similar to morphine. Oxycodone, like morphine and other opioids
used in analgesia, can be abused and is subject to criminal diversion.
Drug addiction is defined as an abnormal, compulsive use, use for non-medical purposes of a substance
despite physical, psychological, occupational or interpersonal difficulties resulting from such use, and
continued use despite harm or risk of harm. Drug addiction is a treatable disease, utilizing a
multidisciplinary approach, but relapse is common. Opioid addiction is relatively rare in patients with
chronic pain but may be more common in individuals who have a past history of alcohol or substance
abuse or dependence. Pseudoaddiction refers to pain relief seeking behavior of patients whose pain is
poorly managed. It is considered an iatrogenic effect of ineffective pain management. The health care
provider must assess continuously the psychological and clinical condition of a pain patient in order to
distinguish addiction from pseudoaddiction and thus, be able to treat the pain adequately.
Physical dependence on a prescribed medication does not signify addiction. Physical dependence
involves the occurrence of a withdrawal syndrome when there is sudden reduction or cessation in drug
use or if an opiate antagonist is administered. Physical dependence can be detected after a few days of
opioid therapy. However, clinically significant physical dependence is only seen after several weeks of
relatively high dosage therapy. In this case, abrupt discontinuation of the opioid may result in a
withdrawal syndrome. If the discontinuation of opioids is therapeutically indicated, gradual tapering of
the drug over a 2-week period will prevent withdrawal symptoms. The severity of the withdrawal
syndrome depends primarily on the daily dosage of the opioid, the duration of therapy and medical
status of the individual.
The withdrawal syndrome of oxycodone is similar to that of morphine. This syndrome is characterized
by yawning, anxiety, increased heart rate and blood pressure, restlessness, nervousness, muscle aches,
tremor, irritability, chills alternating with hot flashes, salivation, anorexia, severe sneezing, lacrimation,
rhinorrhea, dilated pupils, diaphoresis, piloerection, nausea, vomiting, abdominal cramps, diarrhea and
insomnia, and pronounced weakness and depression.
“Drug-seeking” behavior is very common in addicts and drug abusers. Drug-seeking tactics include
emergency calls or visits near the end of office hours, refusal to undergo appropriate examination,
testing or referral, repeated “loss” of prescriptions, tampering with prescriptions and reluctance to
provide prior medical records or contact information for other treating physician(s). “Doctor Shopping”
to obtain additional prescriptions is common among drug abusers and people suffering from untreated
addiction.
Abuse and addiction are separate and distinct from physical dependence and tolerance. Physicians
should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of
physical dependence in all addicts. In addition, abuse of opioids can occur in the absence of true
addiction and is characterized by misuse for non-medical purposes, often in combination with other
psychoactive substances. Oxycodone, like other opioids, has been diverted for non-medical use.
Careful recordkeeping of prescribing information, including quantity, frequency and renewal requests is
strongly advised.
Proper assessment of the patient, proper prescribing practices, periodic reevaluation of therapy, and
proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.
Like other opioid medications, oxycodone and acetaminophen tablets are subject to the Federal
Controlled Substances Act. After chronic use, oxycodone and acetaminophen tablets should not be
discontinued abruptly when it is thought that the patient has become physically dependent on oxycodone.
Interactions with Alcohol and Drugs of Abus e
Oxycodone may be expected to have additive effects when used in conjunction with alcohol, other
opioids, or illicit drugs that cause central nervous system depression.

Following an acute overdosage, toxicity may result from the oxycodone or the acetaminophen.
Signs and Symptoms
Toxicity from oxycodone poisoning includes the opioid triad of: pinpoint pupils, depression of
respiration, and loss of consciousness. Serious overdosage with oxycodone is characterized by
respiratory depression (a decrease in respiratory rate and/or tidal volume, Cheyne-Stokes respiration,
cyanosis), extreme somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and
clammy skin, and sometimes bradycardia and hypotension. In severe overdosage, apnea, circulatory
collapse, cardiac arrest and death may occur.In acetaminophen overdosage: dose-dependent, potentially
fatal hepatic necrosis is the most serious adverse effect. Renal tubular necrosis, hypoglycemic coma
and coagulation defects may also occur.Early symptoms following a potentially hepatotoxic overdose
may include: nausea, vomiting, diaphoresis and general malaise. Clinical and laboratory evidence of
hepatic toxicity may not be apparent until 48 to 72 hours post-ingestion.

Treatment
A single or multiple drug overdose with oxycodone and acetaminophen is a potentially lethal polydrug
overdose, and consultation with a regional poison control center is recommended. Immediate treatment
includes support of cardiorespiratory function and measures to reduce drug absorption. Oxygen,
intravenous fluids, vasopressors, and other supportive measures should be employed as indicated.
Assisted or controlled ventilation should also be considered.
Oxycodone
Primary attention should be given to the reestablishment of adequate respiratory exchange through
provision of a patent airway and the institution of assisted or controlled ventilation. The narcotic
antagonist naloxone hydrochloride is a specific antidote against respiratory depression which may
result from overdosage or unusual sensitivity to narcotics, including oxycodone. Since the duration of
action of oxycodone may exceed that of the antagonist, the patient should be kept under continued
surveillance, and repeated doses of the antagonist should be administered as needed to maintain adequate
respiration. A narcotic antagonist should not be administered in the absence of clinically significant
respiratory or cardiovascular depression.
Acetaminophen
Gastric decontamination with activated charcoal should be administered just prior to N-acetylcysteine
(NAC) to decrease systemic absorption if acetaminophen ingestion is known or suspected to have
occurred within a few hours of presentation. Serum acetaminophen levels should be obtained
immediately if the patient presents 4 hours or more after ingestion to assess potential risk of
hepatotoxicity; acetaminophen levels drawn less than 4 hours post-ingestion may be misleading. To
obtain the best possible outcome, NAC should be administered as soon as possible where impending or
evolving liver injury is suspected. Intravenous NAC may be administered when circumstances preclude
oral administration.
Vigorous supportive therapy is required in severe intoxication. Procedures to limit the continuing
absorption of the drug must be readily performed since the hepatic injury is dose dependent and occurs
early in the course of intoxication.

Dosage should be adjusted according to the severity of the pain and the response of the patient. It may
occasionally be necessary to exceed the usual dosage recommended below in cases of more severe
pain or in those patients who have become tolerant to the analgesic effect of opioids. If pain is constant,
the opioid analgesic should be given at regular intervals on an around-the-clock schedule. Oxycodone
and acetaminophen tablets, USP are given orally.
