Common use
Esperal is primarily used as an adjunct in the management of chronic alcohol dependence. It is prescribed for patients who have undergone 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 regular medical follow-up. It is not intended for use as a standalone therapy or for patients without a definitive diagnosis of alcohol use disorder.
Dosage and direction
The initial dosage of Esperal must be determined by a healthcare provider based on individual patient factors. A typical starting dose is 500 mg daily for the first one to two weeks, often reduced to a maintenance dose of 250 mg daily. The medication should be taken in the morning to coincide with peak temptation periods, though timing may be adjusted per physician advice. It is crucial that the first dose is administered at least 12 hours after the last alcohol consumption to avoid adverse reactions. Dosage adjustments should only be made under medical supervision.
Precautions
Patients must be fully informed about the disulfiram-alcohol reaction, which can occur with even minimal alcohol exposure (including in foods, medications, or toiletries). Regular liver function tests are recommended before and during treatment due to potential hepatotoxicity. Use with caution in patients with diabetes, hypothyroidism, epilepsy, or renal impairment. Avoid concomitant use of alcohol-containing products. Patients should carry identification indicating their use of disulfiram in case of emergency.
Contraindications
Esperal is contraindicated in patients with severe cardiac disease, psychosis, or hypersensitivity to disulfiram or any tablet components. It must not be administered to patients who have consumed alcohol in the past 12 hours. Contraindications also include severe hepatic impairment, pregnancy, and lactation. Use is not recommended in patients with a history of seizures or suicidal ideation without thorough risk-benefit assessment.
Possible side effect
Common side effects may include drowsiness, fatigue, metallic or garlic-like aftertaste, acneiform eruptions, and headache. Less frequently, patients may experience hepatotoxicity, peripheral neuropathy, optic neuritis, or psychiatric symptoms such as depression. The disulfiram-alcohol reaction—characterized by flushing, tachycardia, hypotension, nausea, and vomiting—is an intended pharmacologic effect upon alcohol ingestion but can be severe. Any unusual symptoms should be reported immediately to a healthcare provider.
Drug interaction
Esperal may interact with numerous medications, including phenytoin, warfarin, theophylline, and benzodiazepines, potentially altering their metabolism. Concurrent use with alcohol or alcohol-containing preparations (e.g., cough syrups, tonics) is strictly prohibited. It may also potentiate the effects of central nervous system depressants. Inform your physician of all prescription, over-the-counter, and herbal products you are using.
Missed dose
If a dose is missed, take it as soon as remembered unless it is nearly time for the next dose. Do not double the dose to catch up. Consistent daily adherence is critical to maintain the aversive barrier against alcohol. Discuss any pattern of missed doses with your healthcare provider, as it may indicate a need for additional support or reevaluation of the treatment plan.
Overdose
Symptoms of overdose may include nausea, vomiting, dizziness, lethargy, and neurological symptoms such as seizures. In severe cases, respiratory depression, cardiovascular collapse, or coma may occur. Management is supportive and symptomatic; there is no specific antidote. Gastric lavage may be considered if ingestion is recent. Immediate medical attention is required.
Storage
Store Esperal tablets at room temperature (15–30°C), in a tightly closed container, away from light and moisture. Keep out of reach of children and pets. Do not use beyond the expiration date printed on the packaging.

Reviews
Clinical studies and patient reports consistently affirm Esperal’s role in supporting abstinence among motivated individuals. In controlled trials, disulfiram has demonstrated significant efficacy in reducing drinking days and promoting continuous sobriety when compliance is monitored. Patients often describe it as a pivotal tool in their recovery journey, though success is highly dependent on commitment to comprehensive therapy. Medical professionals emphasize its value within multimodal treatment approaches.
