Antibiotic OTC s: There are essentially three common OTC antibiotic ointments. First is Bacitracin. Second is Polysporin (bacitracin and polymyxin) which is Bacitracin plus Polymyxin B. Neosporin, aka "Triple antibiotic" ointment is Bacitracin + Polymyxin B + Neomycin. Many people (perhaps 1 in 5) are allergic to Neomycin, therefore many dermatologists recommend other options. Aquaphor is a common choice and has no antibiotic in it.
