Bactroban for impetigo: what to know

Bactroban is a brand of mupirocin, a topical antibiotic. A clinician may select it for a limited bacterial skin infection after considering the area involved, the appearance of the sores, previous treatment, and local antibiotic guidance. More widespread, blistering, or severe impetigo may need a different approach.

Mupirocin acts against susceptible bacteria on the skin. Impetigo often produces fragile sores that break and leave yellow-brown crusts, especially around the nose or mouth, although other areas can be involved. Eczema-damaged skin can also be more vulnerable to infection.

A tube left from an earlier illness should not be reused without advice. A rash that resembles impetigo can have another cause, and unnecessary antibiotic use can encourage resistant bacteria or delay the correct diagnosis.

Follow the prescription label for where, how often, and how long to apply the ointment. Wash your hands before and after use, gently clean the affected skin as instructed, and apply only to the prescribed sites. Keep it away from the eyes and inside of the mouth unless a clinician has specifically directed otherwise.

Avoid sharing towels, pillowcases, razors, or the medicine itself. Try not to scratch or pick crusts, keep nails short, and ask when school, nursery, work, swimming, or close-contact activities can safely resume.

Arrange prompt review if sores are spreading, becoming more painful, producing increasing swelling, or failing to improve during the prescribed course. Fever, marked tiredness, red streaking, involvement near the eyes, or extensive blistering also warrant timely assessment.

Stop using the product and obtain urgent help for facial swelling, trouble breathing, or a rapidly developing widespread rash. Tell the prescriber about pregnancy, breastfeeding, kidney problems, medicine allergies, and other products being placed on the same skin.

Ask whether the sores look like impetigo, whether a swab is needed, and what change should be visible before the course ends. Confirm what to do if a dose is missed, whether the area should be covered, and which skin products can be used alongside the ointment.
