What is mupirocin ointment used for?
Mupirocin ointment is a topical antibiotic used to treat certain skin infections caused by susceptible bacteria. It’s commonly prescribed for localized infections such as:
- Impetigo
- Infected cuts or minor skin wounds
- Bacterial infections of the skin (as directed by a clinician)
Why do doctors choose mupirocin instead of another antibiotic?
Mupirocin works by stopping bacteria from making proteins, which helps kill or inhibit bacterial growth on the skin. Because it’s applied directly to the affected area, it’s used when the infection is limited to the surface skin rather than spread throughout the body.
Is mupirocin used for prevention (like MRSA) or only treatment?
It can be used for prevention in specific situations, such as decolonization strategies (for example, reducing carriage of certain bacteria like MRSA) when a clinician recommends it. The exact use depends on the patient’s risk factors and local treatment protocols.
How is mupirocin typically applied?
Patients usually apply it as a thin layer to the affected area and follow the dosing instructions on the prescription. Proper application and hygiene matter because mupirocin works for localized bacterial infections, not for viral illnesses.
What should patients know about bacterial resistance?
Like other antibiotics, repeated or unnecessary use of mupirocin can increase the risk of antibiotic resistance. It’s important to use it only for the condition it was prescribed for and to apply it for the duration directed by a healthcare professional.
When to get medical advice
Seek medical care if the infection:
- Spreads or worsens despite treatment
- Causes fever, increasing pain, swelling, or pus
- Doesn’t improve within the expected timeframe given by the prescriber
