Which side effect may occur as a result of Metronidazole and alcohol interaction?

Metronidazole is known to interact adversely with alcohol, leading to the potential for a disulfiram-like reaction. When alcohol is consumed during or shortly after treatment with Metronidazole, it can cause unpleasant side effects such as nausea and vomiting. This reaction occurs because Metronidazole inhibits aldehyde dehydrogenase, an enzyme responsible for metabolizing acetaldehyde, a toxic byproduct of alcohol metabolism. The accumulation of acetaldehyde when alcohol is ingested can result in the symptoms associated with the disulfiram-like reaction, including severe nausea, vomiting, flushing, and palpitations. Thus, the occurrence of nausea and vomiting is a well-documented consequence of the interaction between Metronidazole and alcohol. Other symptoms may arise with this interaction or from Metronidazole itself, but nausea and vomiting are distinctly linked to the alcohol interaction.
