Question: Is bacitracin ok?


 FearfuL - Sat Feb 19, 2005 10:22 pm

I just read somewhere that bacitracin was toxic, so now it's only good for topical use.

"Bacitracin is toxic to humans and is no longer used internally."

In one of the other topics, Rntdj said topical stuff is absorbed through the skin though, right? I don't really get how it all works, but if I'm using this stuff (on my boob) for about two weeks (I've been advised to), is there anything wrong with that? I don't want toxins like that in my body.

It is OTC though.

Bacitracin is usually combined with Neomycin as a topical preparation for superficial bacterial infections of skin. When used for this purpose, it is safe.

To minimise the development of resistant organisms, it is advisable to limit the choice of antibacterials applied topically to those not used systemically. As Bacitracin is not manufactured or available for systemic use, this makes it ideal for topical use.

Are you using a preparation that contains Bacitracin only, or as a combination with another topical antibiotic?

Hi, Dr. Solomon.

The ointment I'm using is just Bacitracin with its only active labeled ingredient being bacitracin zinc.

It is non-toxic when used topically, but antibacterial effects are broader and better when combined with Neomycin.
