- Using it as a countable noun (e.g., 'a bacitracin').
- Confusing it with oral antibiotics like penicillin.

FAQ
Frequently Asked Questions
No. Neosporin is a brand-name ointment that contains bacitracin along with two other antibiotics (neomycin and polymyxin B). Bacitracin is the specific antibiotic ingredient.
No. Bacitracin is only for topical use on minor skin infections. It is not effective against fungal or viral infections and should not be used on deep wounds, burns, or serious infections without medical advice.
Bacitracin is toxic to the kidneys (nephrotoxic) when absorbed into the bloodstream in significant amounts. Therefore, its use is restricted to topical application where systemic absorption is minimal.
It was discovered in 1945 from a wound contaminated with Bacillus subtilis, isolated from a patient named Margaret Tracy, hence the name 'bacitracin' (from 'Bacillus' + 'Tracy').
