Disulfiram (Antabuse) is used to treat

• A. A medication used to treat alcohol abuse
• B. A medication used to treat anxiety
• C. A medication used to treat depression
• D. A medication used to treat diabetes

Answer: (A)

Disulfiram is used as an aversive treatment for alcohol use disorder. It works by blocking the liver enzyme aldehyde dehydrogenase. If a person taking disulfiram drinks alcohol, acetaldehyde builds up quickly, producing a nasty reaction—facial flushing, sweating, nausea, vomiting, tachycardia, and sometimes dizziness or faintness. The idea is to create a strong negative consequence that discourages drinking, helping the individual stay abstinent when used as part of a broader treatment plan with counseling and support.

It’s not used for anxiety, depression, or diabetes; those conditions are treated with other medications. Because the reaction can be severe, adherence and avoiding any alcohol-containing products (including certain mouthwashes, sauces, or medications) are essential, and liver function should be monitored due to potential toxicity.
