Introduction
In general, alcohol should not be consumed while taking metronidazole tablets. Metronidazole is an antibacterial medication used to treat anaerobic bacterial infections and related conditions. Drinking alcohol after taking metronidazole may trigger a severe disulfiram-like reaction. Symptoms of this reaction include facial flushing, headache, dizziness, palpitations, chest tightness, nausea, vomiting, and difficulty breathing; in severe cases, it may even be life-threatening.

In general, alcohol should not be consumed while taking metronidazole tablets. If any discomfort occurs, it is recommended to seek medical attention promptly. The detailed explanation is as follows:

Metronidazole tablets are an antibacterial medication used to treat conditions such as anaerobic bacterial infections. Drinking alcohol while taking metronidazole may trigger a severe disulfiram-like reaction. Symptoms of this reaction include facial flushing, headache, dizziness, palpitations, chest tightness, nausea, vomiting, and difficulty breathing; in severe cases, it can even be life-threatening. This occurs because metronidazole inhibits aldehyde dehydrogenase in the liver, preventing the further oxidation of acetaldehyde (a metabolite of alcohol) into acetic acid. As a result, acetaldehyde accumulates in the body, leading to a series of toxic symptoms.

Maintaining healthy lifestyle habits and regular dietary patterns can support recovery. If you have any questions or experience discomfort during medication, consult a doctor or pharmacist promptly to ensure safe and effective drug use.
