Propoxyphene Hydrochloride:


Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) hydrochloride and acetaminophen tablets are indicated for the relief of mild-to-moderate pain, either when pain is present alone or when it is accompanied by fever.


Hypersensitivity to Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) or to acetaminophen.


Do not prescribe Propoxyphene; Acetaminophen for patients who are suicidal or addiction-prone.

Prescribe Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) with caution for patients taking tranquilizers or antidepressant drugs and patients who use alcohol in excess.

Tell your patients not to exceed the recommended dose and to limit their intake of alcohol.Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) products in excessive doses, either alone or in combination with other CNS depressants, including alcohol, are a major cause of drug-related deaths. Fatalities within the first hour of overdosage are not uncommon. In a survey of deaths due to overdosage conducted in 1975, in approximately 20% of the fatal cases, death occurred within the first hour (5% occurred within 15 minutes). Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) should not be taken in doses higher than those recommended by the physician. The judicious prescribing of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) is essential to the safe use of this drug. With patients who are depressed or suicidal, consideration should be given to the use of non-narcotic analgesics. Patients should be cautioned about the concomitant use of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) products and alcohol because of potentially serious CNS-additive effects of these agents. Because of its added depressant effects, Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) should be prescribed with caution for those patients whose medical condition requires the concomitant administration of sedatives, tranquilizers, muscle relaxants, antidepressants or other CNS-depressant drugs. Patients should be advised of the additive depressant effects of these combinations. Many of the propoxyphene-related deaths have occurred in patients with previous histories of emotional disturbances or suicidal ideation or attempts, as well as histories of misuse of tranquilizers, alcohol, and other CNS-active drugs. Some deaths have occurred as a consequence of the accidental ingestion of excessive quantities of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) alone or in combination with other drugs. Patients taking Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) should be warned not to exceed the dosage recommended by the physician.


Propoxyphene; Acetaminophen, when taken in higher-than-recommended doses over long periods of time, can produce drug dependence characterized by psychic dependence and, less frequently, physical dependence and tolerance. Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) will only partially suppress the withdrawal syndrome in individuals physically dependent on morphine or other narcotics. The abuse liability of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) is qualitatively similar to that of codeine although quantitatively less, and Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) should be prescribed with the same degree of caution appropriate to the use of codeine.


Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a car or operating machinery. The patient should be cautioned accordingly.




Propoxyphene; Acetaminophen should be administered with caution to patients with hepatic or renal impairment since higher serum concentrations or delayed elimination may occur.


A Patient Information Sheet is available for the product. See text following ANIMAL TOXICOLOGY section below.


The CNS-depressant effect of Propoxyphene; Acetaminophen is additive with that of other CNS depressants, including alcohol.

As is the case with many medicinal agents, Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) may slow the metabolism of a concomitantly administered drug. Should this occur, the higher serum concentrations of that drug may result in increased pharmacologic or adverse effects of that drug. Such occurrences have been reported when Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) was administered to patients on antidepressants, anticonvulsants, or warfarin-like drugs. Severe neurologic signs, including coma, have occurred with concurrent use of carbamazepine.


Safe use in pregnancy has not been established relative to possible adverse effects on fetal development. Instances of withdrawal symptoms in the neonate have been reported following usage during pregnancy. Therefore, Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) should not be used in pregnant women unless, in the judgement of the physician, the potential benefits outweigh the possible hazards.


Low levels of Propoxyphene; Acetaminophen have been detected in human milk. In postpartum studies involving nursing mothers who were given Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride), no adverse effects were noted in infants receiving mother's milk.


Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) is not recommended for use in pediatric patients because documented clinical experience has been insufficient to establish safety and a suitable dosage regimen in the pediatric age group.


The rate of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) metabolism may be reduced in some patients. Increased dosing interval should be considered.


In a survey conducted in hospitalized patients, less than 1% of patients taking Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) hydrochloride at recommended doses experienced side effects. The most frequently reported were dizziness, sedation, nausea, and vomiting. Some of these adverse reactions may be alleviated if the patient lies down.

Other adverse reactions include constipation, abdominal pain, skin rashes, light-headedness, headache, weakness, euphoria, dysphoria, hallucinations and minor visual disturbances. Liver dysfunction has been reported in association with both active components of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) hydrochloride and acetaminophen tablets. Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) therapy has been associated with abnormal liver-function tests and, more rarely, with instances of reversible jaundice (including cholestatic jaundice). Hepatic necrosis may result from acute overdose of acetaminophen. In chronic ethanol abusers, this has been reported rarely with short-term use of acetaminophen dosages of 2.5 to 10 g/day. Fatalities have occurred. Renal papillary necrosis may result from chronic acetaminophen use, particularly when the dosage is greater than recommended and when combined with aspirin. Subacute painful myopathy has occurred following chronic Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) overdosage.



In all cases of suspected overdosage, call your regional Poison Control Center to obtain the most up-to-date information about the treatment of overdosage. This recommendation is made because, in general, information regarding the treatment of overdosage may change more rapidly than do package inserts.

Initial consideration should be given to the management of the CNS effects of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) overdosage. Resuscitative measures should be initiated promptly. SYMPTOMS OF Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) OVERDOSAGEThe manifestations of acute overdosage with Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) are those of narcotic overdosage. The patient is usually somnolent, but may be stuporous or comatose and convulsing. Respiratory depression is characteristic. The ventilatory rate and/or tidal volume is decreased, which results in cyanosis and hypoxia. Pupils, initially pinpoint, may become dilated as hypoxia increases. Cheyne-Stokes respiration and apnea may occur. Blood pressure and heart rate are usually normal initially, but blood pressure falls and cardiac performance deteriorates, which ultimately results in pulmonary edema and circulatory collapse unless the respiratory depression is corrected and adequate ventilation is restored promptly. Cardiac arrhythmias and conduction delay may be present. A combined respiratory-metabolic acidosis occurs owing to retained CO2 (hypercapnia) and to lactic acid formed during anaerobic glycolysis. Acidosis may be severe if large amounts of salicylates have also been ingested. Death may occur. TREATMENT OF Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) OVERDOSAGEAttention should be directed first to establishing a patent airway and to restoring ventilation. Mechanically assisted ventilation, with or without oxygen, may be required, and positive-pressure respiration may be desirable if pulmonary edema is present. The narcotic antagonist naloxone will markedly reduce the degree of respiratory depression, and 0.4 to 2 mg should be administered promptly, preferably intravenously. If the desired degree of counteraction with improvement in respiratory functions is not obtained, naloxone should be repeated at 2-to-3-minute intervals. The duration of action of the antagonist may be brief. If no response is observed after 10 mg of naloxone have been administered, the diagnosis of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) toxicity should be questioned. Naloxone may also be administered by continuous intravenous infusion. TREATMENT OF Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) OVERDOSAGE IN CHILDRENThe usual initial dose of naloxone in children is 0.01 mg/kg body weight given intravenously. If the dose does not result in the desired degree of clinical improvement, a subsequent increased dose of 0.1 mg/kg body weight may be administered. If an IV route of administration is not available, naloxone may be administered IM or subcutaneously in divided doses. If necessary, naloxone can be diluted with Sterile Water for Injection. Blood gases, pH, and electrolytes should be monitored in order that acidosis and any electrolyte disturbance present may be corrected promptly. Acidosis, hypoxia, and generalized CNS depression predispose to the development of cardiac arrhythmias. Ventricular fibrillation or cardiac arrest may occur and necessitate the full complement of cardiopulmonary resuscitation (CPR) measures. Respiratory acidosis rapidly subsides as ventilation is restored and hypercapnia eliminated, but lactic acidosis may require intravenous bicarbonate for prompt correction. Electrocardiographic monitoring is essential. Prompt correction of hypoxia, acidosis, and electrolyte disturbance (when present) will help prevent these cardiac complications and will increase the effectiveness of agents administered to restore normal cardiac function. In addition to the use of narcotic antagonist, the patient may require careful titration with an anticonvulsant to control convulsions. Analeptic drugs (for example, caffeine or amphetamine) should not be used because of tendency to precipitate convulsions. General supportive measures, in addition to oxygen, include, when necessary, intravenous fluids, vasopressor-inotropic compounds, and when infection is likely, anti-infective agents. Gastric lavage may be useful, and activated charcoal can adsorb a significant amount of ingested Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride). Dialysis is of little value in poisoning due to Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride). Efforts should be made to determine whether other agents such as alcohol, barbiturates, tranquilizers, or other CNS depressants, were also ingested, since these increase CNS depression as well as cause specific toxic effects. SYMPTOMS OF ACETAMINOPHEN OVERDOSAGEShortly after oral ingestion of an overdosage of acetaminophen and for the next 24 hours, anorexia, nausea, vomiting, diaphoresis, general malaise and abdominal pain have been noted. The patient may then present no symptoms, but evidence of liver dysfunction may become apparent up to 72 hours after ingestion, with elevated serum transaminase and lactic dehydrogenase levels, an increase in serum bilirubin concentrations, and a prolonged prothrombin time. Death from hepatic failure may result 3 to 7 days after overdosage. Acute renal failure may accompany the hepatic dysfunction and has been noted in patients who do not exhibit signs of fulminant hepatic failure. Typically, renal impairment is more apparent 6 to 9 days after ingestion of the overdose. TREATMENT OF ACETAMINOPHEN OVERDOSAGEAcetaminophen in massive overdosage may cause hepatic toxicity in some patients. In all cases of suspected overdose, immediately call your regional poison control center for assistance in diagnosis and for directions in the use of N-acetylcysteine as an antidote. In adults, hepatic toxicity has rarely been reported with acute overdoses of less than 10 g and fatalities with less than 15 g. Importantly, young children seem to be more resistant than adults to the hepatotoxic effect of an acetaminophen overdose. Despite this, the measures outlined below should be initiated in any adult or child suspected of having ingested an acetaminophen overdose. Because clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours postingestion, liver function studies should be obtained initially and repeated at 24-hour intervals. Consider emptying the stomach promptly by lavage or by induction of emesis with syrup of ipecac. Patients’ estimates of the quantity of a drug ingested are notoriously unreliable. Therefore, if an acetaminophen overdose is suspected, a serum acetaminophen assay should be obtained as early as possible, but no sooner than four hours following ingestion. The antidote, N-acetylcysteine, should be administered as early as possible, and within 16 hours of the overdose ingestion for optimal results. Following recovery, there are no residual, structural or functional hepatic abnormalities.



The product is given orally. The usual dose is 65 mg Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) hydrochloride and 650 mg acetaminophen every 4 hours as needed for pain. The maximum recommended dose of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) hydrochloride is 390 mg per day.

Consideration should be given to a reduced total daily dosage in patients with hepatic or renal impairment.

Some indication of the relative insolubility and retarded absorption of Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) napsylate was obtained by measuring plasma Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) levels in 2 groups of 4 dogs following oral administration of equimolar doses of the 2 salts. As shown in Figure 3, the peak plasma concentration observed with Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) hydrochloride was much higher than that obtained after administration of the napsylate salt.

Although none of the animals in this experiment died, 3 of the 4 dogs given Propoxyphene; Acetaminophen (Propoxyphene Hydrochloride) hydrochloride exhibited convulsive seizures during the time interval corresponding to the peak plasma levels. The 4 animals receiving the napsylate salt were mildly ataxic but not acutely ill.
