Triple antibiotic ointment usually contains bacitracin, polymixin and neomycin in a petrolatum base. There may be some other minor ingredients, but those are the "triple antibiotic" part of the ointment.

The bacteria needs the its cell with to live and protein synthesis to grow and thrive.
Gentamicin ointment is to be used externally for skin infections and such while Gentamicin ophthalmic ointment is for the eyes ONLY!
