Fungal Diaper Rash: What You Should Know

The rash often appears in the creases of the groin and may look bright red, smooth, or shiny. Small separate spots can sit just beyond the main irritated area. Unlike simple irritation from moisture or friction, it may involve the skin folds and persist despite ordinary barrier care. Tenderness, itching, or discomfort during nappy changes can occur. A clinician may distinguish yeast from irritant dermatitis, bacterial infection, or another skin problem by examining the pattern and the surrounding skin.

Change nappies promptly, rinse with lukewarm water or use a fragrance-free cleanser, and pat rather than rub. Allow the area to air briefly when practical, then use a clean, dry nappy and avoid tight clothing. Do not scrub, use fragranced products, or apply leftover prescription creams. A healthcare professional may recommend a product such as [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/). A bland protective moisturiser may also support the skin barrier; see [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) for general information. Follow the product directions and keep treatment away from the eyes and mouth.

Arrange medical advice if the rash is spreading, very painful, oozing, blistered, bleeding, or accompanied by fever or marked swelling. Seek prompt assessment when a baby seems unusually sleepy, feeds poorly, or is difficult to settle. A rash that does not start improving with careful nappy care, or that repeatedly returns, deserves review because the diagnosis or treatment may need changing.

Ask whether the pattern fits yeast or irritant dermatitis, how long to use the recommended treatment, whether a barrier product can be used with it, and which symptoms should prompt an earlier review.
