Antabuse Generic, containing the active ingredient disulfiram, is a cornerstone pharmaceutical intervention for chronic alcohol use disorder. It functions as an aversive therapy by altering the body’s metabolism of alcohol, leading to highly unpleasant physical reactions upon consumption. This mechanism supports long-term abstinence by creating a powerful psychological deterrent, making it a vital tool in comprehensive treatment plans under medical supervision. Its use is indicated for motivated patients committed to sobriety.

Common use

Antabuse Generic is primarily prescribed for the management of chronic alcohol dependence in patients who desire to maintain a state of enforced sobriety. It is used as part of a comprehensive treatment regimen that includes counseling, psychosocial support, and sometimes additional medications. It is most effective in patients who are fully aware of the consequences of alcohol consumption while on the medication and who are committed to a abstinence-based recovery path.

Dosage and direction

The initial dosage is typically 500 mg daily for one to two weeks, often administered as a single dose. Maintenance doses generally range from 125 mg to 500 mg daily, adjusted based on patient tolerance and therapeutic response. The tablet should be taken whole with water, preferably in the morning to maintain consistent daily dosing. It may be taken with or without food. Dosage must be individualized under strict medical supervision. Patients must be alcohol-free for at least 12 hours before initiating therapy.

Precautions

Patients must be fully informed about the disulfiram-ethanol reaction and explicitly warned to avoid all forms of alcohol, including hidden sources in medications, foods, or toiletries. Liver function tests should be performed before treatment and at regular intervals thereafter. Use with caution in patients with diabetes, hypothyroidism, epilepsy, renal impairment, or cardiovascular disease. May cause drowsiness; patients should avoid driving or operating machinery until response is known. Not recommended during pregnancy or breastfeeding unless clearly needed.

Contraindications

Contraindicated in patients with severe myocardial disease, coronary artery disease, psychosis, or hypersensitivity to disulfiram or any tablet component. Should not be administered to patients who are in a state of alcohol intoxication or without their full knowledge. Contraindicated in those taking metronidazole, paraldehyde, or any alcohol-containing preparations.

Possible side effect

Common side effects may include drowsiness, fatigue, headache, metallic or garlic-like aftertaste, and skin eruptions. Less frequently, patients may experience peripheral neuropathy, optic neuritis, hepatitis, or psychotic reactions. The disulfiram-ethanol reaction—characterized by flushing, throbbing headache, respiratory difficulty, nausea, copious vomiting, sweating, thirst, chest pain, palpitations, hyperventilation, tachycardia, hypotension, syncope, marked uneasiness, weakness, vertigo, blurred vision, and confusion—occurs upon alcohol ingestion and can range from mild to severe.

Drug interaction

Disulfiram inhibits aldehyde dehydrogenase and several hepatic microsomal enzymes, potentially increasing serum levels of phenytoin, warfarin, benzodiazepines, tricyclic antidepressants, and theophylline. Concurrent use with alcohol or alcohol-containing preparations (e.g., syrups, elixirs, tonics) is strictly prohibited. May potentiate the effects of central nervous system depressants. Use with isoniazid may result in unsteady gait or marked changes in mental status.

Missed dose

If a dose is missed, it should be taken as soon as remembered unless it is nearly time for the next dose. Do not double the dose to make up for a missed one. Consult a healthcare provider for guidance if multiple doses are missed or if there is uncertainty about restarting therapy.

Overdose

Symptoms of overdose may include nausea, vomiting, dizziness, ataxia, seizures, electrocardiogram changes, and acute neurological disturbances. In severe cases, respiratory depression, cardiovascular collapse, or coma may occur. Treatment is supportive and symptomatic; there is no specific antidote. Gastric lavage may be considered if ingestion was recent. Hospitalization and monitoring of vital signs, electrolyte balance, and liver function are essential.

Storage

Store at room temperature (15–30°C or 59–86°F) in a dry place, protected from light and moisture. Keep in the original container, tightly closed. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
