"I finished my last dose of metronidazole 24 hours ago, can I drink a couple of beers now?"
The medication was for prevention and I was on it for 3 days 6 pills total

The reason for this is not known completely, but we think that the reaction that happens when people drink alcohol while taking this antibiotic is similar to the reaction that occurs when people take disulfiram. Disulfiram was a medication that is used to prevent alcohol abuse.
