What is mupirocin ointment used for?
Mupirocin ointment is an antibiotic used on the skin to treat certain bacterial skin infections. It works by stopping bacteria from making essential proteins, which limits bacterial growth.
What kinds of skin infections does it treat?
Clinicians commonly use mupirocin for localized infections where bacteria are involved, such as infected minor cuts or wounds and other small-area skin infections caused by susceptible bacteria.
How is it usually applied?
It is applied directly to the affected skin area as directed by a clinician or the product label. It is typically used for a short course rather than long-term use.
Why it’s not for routine colds, flu, or viral skin rashes
Because mupirocin is an antibiotic, it does not treat viral illnesses. It also won’t help if a rash or skin problem is caused by something other than bacteria.
What patients often ask about: side effects and when to stop
Common skin-related reactions can include burning, stinging, or irritation at the application site. Contact a clinician promptly if symptoms worsen, spread, or there are signs of an allergic reaction.
How to prevent antibiotic resistance
Using mupirocin only when it’s appropriate, applying it exactly as directed, and not using it longer than prescribed helps reduce the risk of antibiotic resistance.
