Disulfiram is an FDA-approved medication for alcohol use disorder that is designed to support abstinence by causing an unpleasant physical reaction if alcohol is consumed. It does not reduce acute alcohol withdrawal and does not directly block alcohol cravings.
How does disulfiram work?
Disulfiram blocks an enzyme involved in alcohol metabolism, causing acetaldehyde to build up if alcohol is consumed. This can lead to flushing, headache, nausea, vomiting, sweating, palpitations, and other potentially serious symptoms.
Who may be a good candidate?
It may be considered for people whose goal is abstinence and who understand the alcohol-disulfiram reaction. Adherence and supervision can be important because the medication works only when taken consistently.
Can someone drink alcohol while taking disulfiram?
No. Alcohol should be avoided. Alcohol can also be present in some medications, mouthwashes, cooking products, and topical products, so patients should follow clinician and pharmacist guidance.
Does disulfiram treat alcohol withdrawal?
No. It is not a withdrawal-management medication. Acute alcohol withdrawal can be dangerous and should be assessed separately.
How is disulfiram different from naltrexone or acamprosate?
Naltrexone can reduce alcohol reward and craving, while acamprosate supports abstinence after drinking has stopped. Disulfiram creates an aversive reaction to alcohol. See Trinity’s overview of AUD medications.
What safety issues matter?
Clinicians consider liver health, heart disease, psychiatric conditions, other medications, and the patient’s ability to avoid alcohol. Disulfiram should be prescribed and monitored by a qualified clinician.

Frequently asked questions
Does disulfiram reduce cravings?
It is not primarily a craving-reduction medication; its main effect is making alcohol consumption unpleasant and potentially dangerous.
Can the alcohol reaction continue after stopping disulfiram?
Yes. The effect can persist after the last dose, so clinicians provide specific guidance about how long alcohol must be avoided.
Is disulfiram addictive?
No. It is not a controlled substance and does not produce intoxication.
