Question

Quizplus · Accepted Answer

Individuals taking metronidazole and tinidazole should not drink alcoholic beverages because metronidazole produces a disulfiram-like reaction with alcohol that can be very unpleasant. Acetaldehyde dehydrogenase, an enzyme in the metabolism of alcohol that converts acetaldehyde to acetic acid, is inhibited by disulfiram. This inhibition causes greater accumulation of acetaldehyde in the blood, which results in an immediate reaction of flushing, nausea, headache, tachycardia, shortness of breath, and possible collapse. Metronidazole and tinidazole produce a similar condition when taken with alcohol.
