For abrasions, minor cuts and wounds, the use of mupirocin may prevent the development of infection by sensitive Gram-positive organisms.

No cross-resistance has been shown between mupirocin and other commonly used antibiotics.

As with other PEG based ointments, mupirocin ointment should not be used in conditions where absorption of large quantities of PEG is possible, especially if there is evidence of moderate or severe renal impairment.

In the rare event of a possible sensitization reaction or severe local irritation occurring with the use of mupirocin, treatment should be discontinued and appropriate alternative therapy for the infection instituted.

Precautions: Use of topical antibiotics occasionally allows overgrowth of non-susceptible organisms. If this occurs, or irritation or sensitization develop, treatment should be discontinued and appropriate therapy instituted.

If administration to pregnant patients is considered necessary, its potential benefits should be weighed against the possible hazards to the fetus. Caution should be exercised when mupirocin ointment is administered to nursing mothers.
