How to get rid of impetigo

Impetigo is a superficial bacterial infection that often causes red sores, blisters, or yellow-brown crusts around the nose and mouth, on the hands, or on exposed skin. It can enter through a scratch, insect bite, or area affected by eczema such as atopic dermatitis. The infection can spread when fluid from a sore reaches another person or another part of the body.

A clinician can distinguish impetigo from other causes of crusting skin by examining the pattern and symptoms. Avoid sharing towels, razors, clothing, bedding, or cosmetics while sores are active.

Use topical antibiotic therapy when prescribed for a small, limited area, or oral antibiotics for more extensive infection or when a clinician considers them necessary. Clean gently with soap and water, soften crusts without picking, wash hands after touching the area, and cover lesions with a clean dressing when practical.

Keep fingernails short and discourage scratching in children. Wash clothing, towels, and bedding regularly, and follow the prescribed course even if the skin begins to look better. Do not use leftover antibiotics or share a prescription.

Arrange medical review promptly for rapidly spreading sores, significant pain, fever, swelling around the eye, or a child who seems unusually unwell. Seek advice if lesions do not improve with prescribed treatment, keep returning, or involve a newborn or someone with reduced immunity. Urgent assessment is needed for severe illness or eye symptoms.

Ask which antibiotic route is suitable, how long the area remains contagious, how to clean and cover the sores, and what to do if a household contact develops similar lesions.
