Bacitracin^[1] is a polypeptide antibiotic. It is a mixture of related cyclic peptides produced by Bacillus licheniformis bacteria, that was first isolated from the variety "Tracy I" (ATCC 10716) in 1945.^[2] These peptides disrupt Gram-positive bacteria by interfering with cell wall and peptidoglycan synthesis.

Bacitracin is primarily used as a topical preparation, as it can cause kidney damage when used internally.^[3] It is generally safe when used topically, but in rare cases may cause hypersensitivity, allergic or anaphylactic reactions, especially in people allergic to neomycin.^[4]^[5]

In 2022, it was the 323rd most commonly prescribed medication in the United States, with more than 100,000 prescriptions.^[6]
