Common use
Antabuse is primarily prescribed for the management of chronic alcohol dependence in patients who want to remain in a state of enforced sobriety. It is typically indicated for individuals who have undergone alcohol detoxification and are committed to maintaining abstinence. The medication is most effective when used as part of a comprehensive treatment program that includes psychological support, counseling, and participation in support groups. Healthcare providers prescribe Antabuse for patients who understand the consequences of alcohol consumption while taking the medication and who have demonstrated motivation for sustained recovery.
Dosage and direction
The initial dosage is typically 500 mg daily for one to two weeks, followed by a maintenance dose of 125 mg to 500 mg daily. dosage must be individualized based on patient response and tolerance. The medication should be taken in the morning, as the deterrent effect may be more pronounced during daytime hours when alcohol consumption is more likely. Patients must be completely alcohol-free for at least 12 hours before initiating therapy. Tablets should be swallowed whole with water, and the medication is most effective when taken consistently at the same time each day. dosage adjustments should only be made under medical supervision.
Precautions
Patients must be thoroughly informed about the Antabuse-alcohol reaction and must avoid all alcohol-containing products, including medications, foods, toiletries, and topical preparations. Regular medical monitoring is essential during treatment. Liver function tests should be performed before initiation and at regular intervals during therapy. Patients should carry identification indicating they are taking disulfiram. The medication should be used with caution in patients with diabetes mellitus, hypothyroidism, epilepsy, cerebral damage, chronic or acute nephritis, hepatic impairment, or cardiovascular disease. Pregnancy and breastfeeding require special consideration and medical consultation.
Contraindications
Antabuse is contraindicated in patients with severe myocardial disease, coronary artery disease, psychosis, or hypersensitivity to disulfiram or other thiuram derivatives. It should not be administered to patients who are in a state of alcohol intoxication or without their full knowledge. Contraindications include concomitant use with alcohol-containing preparations, metronidazole, paraldehyde, or certain other medications. Patients with severe hepatic impairment or hepatitis should not receive disulfiram therapy. The medication is contraindicated in patients who cannot commit to complete alcohol abstinence.
Possible side effects
Common side effects include drowsiness, fatigue, headache, metallic or garlic-like aftertaste, and skin eruptions. These typically diminish with continued therapy. More serious side effects may include hepatotoxicity, polyneuritis, peripheral neuropathy, optic neuritis, and psychiatric symptoms including depression. The most significant adverse effect is the disulfiram-alcohol reaction, characterized by flushing, throbbing headache, respiratory difficulty, nausea, vomiting, sweating, thirst, chest pain, palpitations, tachycardia, hypotension, syncope, marked uneasiness, weakness, vertigo, blurred vision, and confusion. Severe reactions may include respiratory depression, cardiovascular collapse, arrhythmias, myocardial infarction, acute congestive heart failure, unconsciousness, convulsions, and death.
Drug interaction
Antabuse interacts with numerous medications including warfarin (increased anticoagulant effect), phenytoin (increased serum levels), benzodiazepines (prolonged sedative effect), theophylline (decreased clearance), tricyclic antidepressants (increased levels), and metronidazole (increased risk of psychotic reactions). It may also interact with alcohol-containing preparations, paraldehyde, and certain antiretroviral medications. Patients should inform all healthcare providers about Antabuse use before starting any new medication, including over-the-counter products and herbal supplements.
Missed dose
If a dose is missed, it should be taken as soon as remembered unless it is almost time for the next scheduled dose. Patients should not double the dose to make up for a missed one. Consistency in dosing is important for maintaining the deterrent effect, but occasional missed doses are less critical than maintaining the treatment regimen overall. Patients should contact their healthcare provider if multiple doses are missed or if they have questions about dosing schedule adjustments.
Overdose
Symptoms of overdose may include nausea, vomiting, dizziness, lethargy, incoordination, seizures, and respiratory depression. In severe cases, overdose may lead to coma, cardiovascular collapse, and death. Management includes gastric lavage if presented early, supportive care, and symptomatic treatment. There is no specific antidote for disulfiram overdose. Hemodialysis may be considered in severe cases. Patients suspected of overdose should receive immediate medical attention with monitoring of vital signs and neurological status.
Storage
Store at controlled room temperature between 20°C to 25°C (68°F to 77°F). Keep in the original container with the lid tightly closed. Protect from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.

Reviews
Clinical studies demonstrate that Antabuse, when used as part of a comprehensive treatment program, significantly improves abstinence rates compared to placebo. Many addiction specialists report successful outcomes in motivated patients who understand the medication’s mechanism and consequences. Patient experiences vary, with some reporting excellent results in maintaining sobriety, while others note side effects that require dosage adjustment or discontinuation. The effectiveness largely depends on patient motivation, comprehensive treatment approach, and consistent medical supervision.
