Mupirocin ointment should generally not be applied to the mouth. It is a topical antibiotic primarily used to treat skin infections caused by Gram-positive cocci. This medication is intended for use on the skin surface only and must not be applied to mucosal areas such as the eyes, nose, or oral cavity. Local adverse reactions—such as swelling or rash—may occur at the application site.
