Impetigo: what to know before visiting a pharmacy

Impetigo is a contagious bacterial infection of the surface skin. It often begins around a scratch, insect bite, eczema patch or irritated area, then forms oozing spots that dry into yellow or honey-coloured crusts. It can occur on the face, hands or other exposed skin, and is easily passed by touch or shared towels. Crusting skin can have several causes, so a pharmacist or clinician may need to look at the rash rather than relying on a product name. Existing atopic dermatitis can make broken skin more vulnerable to infection.

Gently wash the affected area with clean water and mild soap, soften crusts without picking, pat dry and cover loosely with a clean dressing. Wash hands after touching the area, keep nails short, and avoid sharing towels, clothing, bedding or cosmetics. A pharmacist can advise whether an assessment is appropriate and whether a topical treatment may fit the pattern. Do not use leftover antibiotics or put a product near the eyes unless a professional says it is suitable. Keep reading about topical antibiotic therapy for skin infections.

Arrange prompt medical review if the rash is spreading, painful, warm, swollen or producing increasing discharge; if there are many lesions; or if the eye area, lips or genitals are involved. Seek urgent help for fever, marked illness, rapidly worsening swelling or trouble seeing. Children who are very unwell, or anyone with reduced immune protection, may need earlier assessment. A clinician can decide whether oral antibiotics for a skin infection are needed.

Ask: Does this look like impetigo or another rash? Is a topical medicine enough? How should the area be cleaned and covered? When can the child return to school or childcare? What should I do if new spots appear after treatment starts? Mention eczema, allergies, recent medicines and any contact with someone who has a similar rash.
