Can i drink alcohol when i am on antibiotics?

Limited: It depends on the antibiotic. The only one that causes serious adverse reaction consistently is Metronidazole (also called Flagyl).

Yes you can, BUT: it always worries me when people find drinking so important that they need to ask this kind of a question. I would also wonder what kind of infection is being treated, and HOW MUCH ALCOHOL you are talking about. Alcohol decreases the activity of white blood cells that fight infection and make antibodies, and it is not the best thing to take when you are trying to cure an infection. Talk to doctor

Sometimes: Some antibiotics interact with acohol to give the patient symptoms such as nausea and vomting (flagyl) or flushing, and rash (mefoxitin). Cceck with your doctor or pharmacist.

Depends: That depends on the antibiotic. In most cases it's ok, but people taking Metronidazole (flagyl) or tinidazole (tindamax) should wait until at least 48 hours after the last dose.
