bacitracin
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.”
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).
