Best Answer

polymyxin can damage other living cell membranes, but since the top layer of your skin is composed of mostly dead, it's safe to use on it.

Does Neomycin or Polymyxin B have penicillin in it?

Polymyxin B does not have penicillin in it, I just called my local pharmacy to ask that question and the answer is no. I should note, however, that the reason I called my pharmacist was because I used a topical ointment that contained Polymyxin B and had a very severe allergic reaction immediately after applying the ointment. I have anaphylaxis to penicillin and thought it may contain penicillin, but the pharmacist tells me it does not. He did advise me to go see my allergist again as I may have developed an allergy to another antibiotic but assured me there is no penicillin in Polymyxin B. Can't help with Neomycin, sorry!
