Used topically and systemically to treat bacterial infections, particularly those caused by Gram-positive bacteria such as Staphylococcus aureus, including methicillin-resistant strains (MRSA). Commonly formulated in creams, ointments, and eye drops for skin and ocular infections. Also available in oral and intravenous forms for more severe or systemic infections. Often reserved for cases where other antibiotics are ineffective or contraindicated due to its specific mechanism of action and low resistance development when used appropriately.
