Bacitracin is a type of antibiotic that is primarily used to treat bacterial infections. Synonyms for bacitracin include bacitracin zinc, baciim, and baciguent. These medications all contain the active ingredient bacitracin, and can be used to treat a wide variety of bacterial infections. Bacitracin zinc is often used in topical treatments for skin infections, while baciim and baciguent may be used for infections of the eyes or lungs. In addition, other antibiotics like amoxicillin, cephalexin, and penicillin may also be used to treat bacterial infections, depending on the type of infection and the patient's medical history.
