Which medication may cause symptoms such as palpitations and flushing if alcohol is consumed while taking it?

Disulfiram is the medication in question that can cause symptoms such as palpitations and flushing when alcohol is consumed simultaneously. This medication is specifically used in the treatment of chronic alcoholism by discouraging the consumption of alcohol. Its mechanism involves inhibiting the enzyme acetaldehyde dehydrogenase, leading to a buildup of acetaldehyde in the body when alcohol is ingested. This buildup can precipitate a range of unpleasant symptoms, commonly known as the disulfiram-alcohol reaction, which includes palpitations, flushing, nausea, vomiting, and even more severe reactions.

This deterrent effect is precisely why disulfiram is utilized as part of a comprehensive treatment strategy for individuals struggling with alcohol dependence, aiming to promote abstinence by associating alcohol intake with negative physiological responses. The awareness of potential side effects reinforces the importance of patient education regarding the need to avoid alcohol completely while undergoing treatment with disulfiram.
