Bacitracin Ointment Skin Eye Uses Side Effects Dosage

bacitracin topical

Bacitracin topical is an antibiotic ointment used to prevent infection in minor skin injuries such as cuts, scrapes, and burns. It is also used to treat infections in the eye and eyelids.

Bacitracin is a mixture of cyclic polypeptide antibiotics that inhibit bacterial growth and kill bacteria. By preventing the transfer of mucopeptides to the bacterial cell wall, bacitracin disrupts cell wall synthesis and bacterial growth. It also inhibits enzymes involved in bacterial cell membrane functions.

Bacitracin is available over the counter (OTC) for topical use and requires a prescription for ophthalmic use. It is primarily effective against gram-positive bacteria and some gram-negative bacteria. Gram-negative bacteria have an additional outer membrane that gram-positive bacteria lack, making them less susceptible to bacitracin.

Susceptible organisms include:

Staphylococcus species (including some penicillin G resistant strains), Streptococcus species, Corynebacterium species, Clostridium species, anaerobic cocci, gonococci, meningococci (Neisseria species), fusobacteria, Treponema pallidum, Treponema vincentii, and Actinomyces species.

Warnings

  • Do not use bacitracin if you are hypersensitive to any of its components.
  • Topical antibiotics can induce immune reactions, including immediate or delayed reactions.
  • Allergic skin reactions, including rash and contact dermatitis, as well as serious hypersensitivity reactions such as anaphylaxis, have been reported with bacitracin.
  • Patients sensitive to bacitracin may also be cross-sensitive to polymyxin B.
  • Do not use bacitracin in the external ear canal if you have a perforated eardrum.
  • Use ophthalmic ointment for eye infections, not the OTC topical formulation.
  • Do not use bacitracin if you have a hypersensitivity disorder (atopy).
  • Do not use bacitracin for deep-seated eye infections or those that can become systemic.
  • Prolonged use of topical or ophthalmic antibiotics can lead to overgrowth of nonsusceptible organisms, including fungi.
