No - the NHS says avoid alcohol completely while taking metronidazole and for 2 days after the last dose, because it blocks alcohol breakdown and the buildup causes feeling and being sick, stomach pain, hot flushes, pounding heartbeat, and headache.
The rule covers tablets, liquid, and suppositories, and vaginal gel can sometimes trigger the reaction too; skin cream or gel is less likely to. Watch hidden alcohol in mouthwashes and liquid medicines. Already drank? Stop, and tell your prescriber - do not quit the antibiotic without asking.

What to do
Common questions
Can I drink alcohol on metronidazole?
No - this is one of the few absolute alcohol rules in medicine. The NHS says do not drink alcohol while taking metronidazole tablets or liquid, or using suppositories, and continue to avoid it for 2 days after you finish treatment, giving the drug time to leave your body. The reason: metronidazole blocks the breakdown of alcohol, so acetaldehyde - the hangover chemical - piles up. The reaction: feeling and being sick, stomach pain, hot flushes, a pounding heartbeat, and headache. It is miserable, not dangerous for most people, but entirely avoidable. Alcohol during vaginal gel use can sometimes trigger it too; with skin cream or gel it is less likely because so little is absorbed. Watch hidden alcohol too - some mouthwashes and liquid medicines contain it. If you drank before realizing, skip further drinks and mention it to your prescriber; do not stop the antibiotic without asking.
