Antabuse

Generic name: Disulfiram
Drug class: Drugs used in alcohol dependence

Usage of Antabuse

Antabuse blocks an enzyme that is involved in processing alcohol. Disulfiram produces very unpleasant side effects (such as fast heartbeat, chest pain, nausea, dizziness, flushing, and thirst) when combined with alcohol in the body.

Antabuse is used in certain people with chronic alcoholism. This medicine can help keep you from drinking because of the unpleasant side effects that will occur if you consume alcohol while taking Antabuse.

Antabuse is used together with therapy and counseling support to help you stop drinking. This medicine is not a cure for alcoholism.

Antabuse side effects

Get emergency medical help if you have any of these signs of an allergic reaction to Antabuse: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Even small amounts of alcohol can produce unpleasant symptoms while Antabuse is in your body. These symptoms include:

flushing (warmth, redness, or tingly feeling);

sweating, increased thirst, swelling, rapid weight gain;

nausea, severe vomiting;

neck pain, throbbing headache, blurred vision;

chest pain, shortness of breath (even with mild exertion);

fast or pounding heartbeats or fluttering in your chest;

confusion, weakness, spinning sensation, feeling unsteady; or

a light-headed feeling, like you might pass out.

More severe symptoms may occur when Antabuse and large amounts of alcohol are used together, such as severe chest pain spreading to your jaw or shoulder, slow heart rate, weak pulse, seizure, fainting, weak or shallow breathing, or slow breathing (breathing may stop). A disulfiram-alcohol reaction can be fatal.

Call your doctor at once if you have:

eye pain or sudden vision loss;

numbness or tingling;

confusion, unusual thoughts or behavior; or
