What are the treatment options for impetigo?

Impetigo is a contagious bacterial infection of the surface of the skin. It often causes small blisters or sores that break and form yellow-brown crusts, commonly around the nose, mouth or on exposed skin. A clinician considers the number and location of lesions, whether they are spreading, and whether deeper infection or another diagnosis is possible. Treatment choice should match the extent and severity rather than appearance alone.

For a small, localised area, a prescribed topical antibiotic may be applied after gentle cleansing as directed. When lesions are numerous, spreading, recurrent or accompanied by deeper inflammation, an oral antibiotic may be used. Complete the prescribed course and do not share medicine. Wash hands after touching the area, keep sores covered when practical, avoid picking, and do not share towels, razors or clothing. Children may need guidance about staying home from close-contact activities until a clinician considers them less contagious.

Seek medical advice promptly if the rash is spreading quickly, painful, hot or swollen, or if you feel feverish or unwell. Urgent assessment is needed for swelling around the eye, severe tenderness, extensive blistering or signs of dehydration. Recurrent impetigo also warrants review for contributing skin problems or household spread.
