Q

What should you avoid when taking any abx, but especially metronidazole?

A

Alcohol should not be consumed even up to three days after treatment.
When a person consumes alcohol, the body breaks it down in two steps. First, it breaks alcohol into acetaldehyde. Acetaldehyde is toxic and responsible for the unwanted effects of alcohol.

Next, the body reduces acetaldehyde to acetate. It does this aldehyde dehydrogenase. Flagyl blocks the effects of this enzyme.

As a result, a person on Flagyl cannot fully digest alcohol, and drinking can cause the toxic acetaldehyde to build up in the bloodstream.

Because of this, people who drink alcohol while taking Flagyl may experience a disulfiram-like reaction.
