You should completely avoid alcohol while taking the antibiotics metronidazole or tinidazole, and for 48 hours afterwards, as this combination can cause very unpleasant side effects, such as:
- feeling and being sick
- stomach pain
- hot flushes
It’s recommended that you don’t drink alcohol while taking antibiotics. However, as long as you drink in moderation, alcohol is unlikely to interact significantly with your medication.
Check with your doctor or pharmacist when you are given your prescription if you are unsure about whether or not you can drink alcohol while you are taking antibiotics. You can also phone NHS 111 for advice.
