Can you take antibiotics while on chemotherapy?

No one can give an answer to that on Answers.com, not even a doctor. Don't ask your really smart friend or your cancer support group either. If any of those people says "yes" (or "no" for that matter) don't take their Word for it. As a general rule, to be on the safe side, it's probably best not to take anything while on chemo without your own doctor's permission. Even if another doctor prescribes something, but doesn't know and duly consider that you are on chemo and exactly which chemo drugs at that, call your own doctor before taking it and never go to that other doctor again.

Really. Chemo messes with your body in so many different ways that only a Doctor Who knows all of your details can tell you what's safe to take with it and what's not. There are some things the internet just can't, or shouldn't answer for you.
