What should you know about miconazole nappy rash?

Nappy rash can result from moisture, friction, irritants, or infection. A fungal component may be suspected when redness persists in the skin folds or has small spots around the main irritated area, but a baby’s rash still needs a careful look. Miconazole is an antifungal, so it will not address every cause of nappy rash. A clinician or pharmacist can help distinguish irritation from infection.

Change nappies promptly, clean gently with lukewarm water or a mild fragrance-free cleanser, and pat rather than rub. Allow the skin to dry before applying any recommended medicine. Use miconazole exactly as directed and keep it away from the eyes and mouth. A protective barrier or [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) may help reduce contact with moisture; ask whether it should be used alongside the antifungal. Learn more about [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/). Avoid talc, fragranced wipes, and tight nappies.

Arrange a review if the rash is not settling, keeps returning, spreads beyond the nappy area, or causes marked discomfort. Seek prompt care for fever, blisters, open sores, pus, bleeding, widespread peeling, or a baby who seems unusually sleepy or unwell. Stop and seek advice if the product causes pronounced swelling or irritation.

Does this look like irritation, fungal infection, or another rash? How often should miconazole be applied, and for how long? Which barrier product is suitable, and when should the baby be rechecked?
