Bacitracin : Uses, Side Effects & Dosage

Bacitracin is a mixture of related cyclic peptides produced by organisms of the licheniformis group of Bacillus subtilis var Tracy, first isolated in 1945. These peptides disrupt Gram-positive bacteria by interfering with cell wall and peptidoglycan synthesis.

IT is primarily used as a topical preparation (as it can cause kidney damage when used internally).

Antibiotics such as bacitracin have been shown to act as dermatological irritants and may slow healing in otherwise sterile wounds.
It can also be bought in pure form for those with allergies to the polymyxin B and neomycin components of the combination product.

Bacitracin is also commonly used as an aftercare antibiotic on tattoos and circumcision. It is preferred over combination products such as Neosporin because of its fewer ingredients, which lowers chances of an allergic reaction.
