Home remedies for extreme diaper rash

Nappy rash develops where moisture, stool, urine and friction irritate delicate skin. Severe rash may look intensely red, raw, swollen or cracked, and can cause marked discomfort during cleaning or passing urine or stool. A yeast infection, bacterial infection, allergy or another skin condition can resemble irritation, so a persistent rash should not be treated with a succession of home mixtures.

Change wet or soiled nappies promptly. Rinse with lukewarm water or use fragrance-free, alcohol-free wipes, then pat dry without rubbing. Apply a generous layer of a bland protective ointment at each change; [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) explains how moisturising barriers support irritated skin. Give short periods without a nappy when practical, keep clothing loose and avoid fragranced soaps, talc, scrubbing and antiseptics. Do not use steroid, antibiotic or antifungal products unless a clinician advises them. If the rash has sharply defined edges, small surrounding spots or folds involved, ask whether [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) is appropriate.

Seek prompt medical advice for raw or blistered skin, open sores, pus, yellow crusts, bleeding, rapidly spreading redness, swelling, fever or a child who seems unusually unwell. Arrange an appointment when severe discomfort prevents sleep, feeding or normal movement, or when careful nappy care is not helping. Urgent help is needed if the child is difficult to wake, drinking poorly or showing signs of dehydration.

Could this be irritation, yeast, bacteria or an allergy? Which barrier product should I use? Does the rash need a prescribed treatment? How should I clean open skin, and which changes require urgent review?
