Drug Interactions
Mupirocin is applied topically and has minimal systemic absorption, so true pharmacokinetic drug-drug interactions are rare. The clinically relevant cautions are local rather than systemic.
- Other topical products applied to the same site (e.g., topical corticosteroids, emollients, other antibiotics): Concurrent application can dilute mupirocin and reduce its concentration at the infection site. Apply mupirocin first and let it absorb before applying other topicals, or separate by at least 30 minutes.
- Polyethylene glycol-containing ointments on large open wounds: The ointment vehicle can be absorbed through extensive denuded skin and stress renal function in patients with significant kidney impairment. Use the cream formulation on large or weeping lesions.
- Live nasal influenza vaccine: Intranasal mupirocin may inactivate live nasal vaccine virus. Separate intranasal mupirocin from live attenuated influenza vaccine administration.
- Routine systemic antibiotics: Because mupirocin acts only locally, it does not meaningfully change systemic antibiotic exposure when both are used together.
