An antibiotic used primarily for eye and skin infections. It is available as an ointment, and is found in other “combination” medications like neosporin and polysporin. Interesting tidbit about this drug: it was discovered at Columbia University (my alma mater) in 1943, and derived from a strain of Bacillus bacteria found in a 7-year-old girl named Margaret Tracy. The researchers therefore named the drug “baci-tracin.”

  1. Bacitracin is available as a generic ointment and I use it regularly. You can also buy bacitracin in giant tubes over the counter … I DON’T recommend using the non-prescription gel in your eyes. I’ve tested the over-the-counter bacitracin in my own eyes and it stung a little. The prescription ophthalmic ointment is better (I wish it were cheaper).
