What does mupirocin ointment used for?

Mupirocin ointment is a topical antibiotic used to treat certain bacterial skin infections. Common uses include:

- Impetigo (a contagious skin infection) and similar superficial infections
- Infected minor wounds, cuts, scrapes, boils, or folliculitis
- Some cases of infected eczema (as directed by a clinician)

Note: It is not effective against viral or fungal infections. Nasal mupirocin is used (in a nasal form, not the standard skin ointment) to decolonize Staphylococcus aureus carriers in some settings.

How to use (general guidance):
- Apply a thin layer to the affected skin 2–3 times daily for 3–5 days, or as your clinician directs.
- Clean and dry the area first; wash hands before and after use.
- Do not cover with tight bandages unless advised.
- Avoid contact with eyes, nose, mouth, or other mucous membranes.

Possible side effects:
- Local burning, stinging, itching, or redness
- Rare allergic reactions or rash

When to see a doctor:
- If no improvement after about 5 days
- If symptoms worsen or new fever develops
- If you have signs of an allergy or severe skin reaction

If you’re pregnant, breastfeeding, or using it for a child, check with a clinician for safety and dosing.
