What Is the First Treatment for Intertrigo?

Intertrigo is inflammation where skin rubs against skin, often in the groin, underarms, under the breasts, or between abdominal folds. Heat, sweat, and friction can damage the skin barrier. Once the area is irritated, yeast or another fungus may grow more easily. A clinician may recommend a topical antifungal when the rash has features of fungal involvement, such as a spreading edge or small nearby spots. A prescription antiperspirant may be considered when persistent sweating keeps the fold damp.

Wash gently, rinse away all cleanser, and pat the fold fully dry rather than rubbing it. Choose loose, breathable clothing and change damp garments promptly. Avoid fragranced products and vigorous scrubbing on broken skin. Use any antifungal exactly as directed and continue for the advised course, even if the redness settles early. Do not share towels, and wash clothing that touches the rash. A clinician can check whether the problem is fungal, bacterial, or mainly friction-related before adding another treatment.

Arrange a medical review if the rash is spreading, painful, cracked, oozing, foul-smelling, or not improving with careful drying and the advised treatment. Seek prompt care for fever, rapidly increasing redness, marked swelling, or feeling unwell, because these can signal a more significant infection. People with diabetes, reduced immunity, or repeated episodes should be assessed earlier.

Ask whether the rash looks fungal or whether another cause needs testing. You can also ask how long to use the topical treatment, how to control sweating in the affected fold, and which warning signs should bring you back.
