Can you drink alcohol while on an antibiotic for a bacterial infection?

This depends on what you mean by "drink alcohol" <g> The only antibiotic that you absolutely CANNOT have any alcohol whatever is Flagyl or metronidazole - even splashing alcohol on your skin while taking that drug will make you vomit! It is generally not a good idea to drink lots of alcohol when your body is trying to heal from any infection. Alcohol slows everything down in your body and brain, and drinking more than maybe ONE drink the whole time you are on the antibiotic could make the infection last longer. The actual medication does not have any interaction with the alcohol like metronidazole does, though.
