Disulfiram

What is Disulfiram used for?

Disulfiram is primarily indicated for the treatment of alcohol dependence. It is used as part of a comprehensive treatment program to help individuals who are committed to abstaining from alcohol. Disulfiram works by causing an unpleasant reaction when alcohol is consumed, discouraging drinking and supporting long-term abstinence.

How does Disulfiram work?

Disulfiram works by inhibiting the enzyme aldehyde dehydrogenase in the liver, which is responsible for breaking down acetaldehyde, a byproduct of alcohol metabolism. When alcohol is consumed, acetaldehyde builds up in the body, causing a severe reaction including flushing, nausea, vomiting, and headache. This unpleasant reaction discourages individuals from drinking alcohol while on the medication.
