What should you know about curing impetigo at home?

Impetigo is a contagious bacterial infection affecting the surface of the skin. It can begin around a scratch, insect bite, eczema patch, or irritated area, then form blisters, oozing spots, or yellow-brown crusts. Gently washing the area and keeping it covered helps reduce contact with the fluid and crusts. Avoid picking, sharing towels, clothing, bedding, or razors, and wash hands after touching the area. Crusting skin can have several causes, so a clinician may need to distinguish impetigo from another rash.

Clean the affected skin with lukewarm water and a gentle cleanser, then pat it dry. Use a clean dressing if clothing or fingers rub the area. Keep nails short, wash towels and clothes regularly, and avoid swimming or close skin contact until a clinician says it is appropriate. Do not put leftover antibiotics, steroid cream, antiseptic concentrates, or household products on the rash. A clinician may prescribe topical antibiotic therapy for a small, localised infection or antibiotics for skin infection when wider treatment is needed.

Arrange prompt medical advice if the rash is spreading, painful, repeatedly returning, or affecting the eyes, lips, or a large area. Seek urgent care for fever, marked swelling, increasing warmth, severe tenderness, pus, unusual sleepiness, or a child who seems significantly unwell. Medical review is also sensible when eczema is cracked or weeping, because atopic dermatitis can become infected and may need a coordinated treatment plan.

Ask whether the appearance fits impetigo, whether a swab is needed, which areas should be treated, and how long close-contact precautions should continue. Confirm when school, nursery, work, exercise, or swimming can safely resume.
