Intertrigo treatment at home

In intertrigo, two surfaces rub while heat and trapped sweat keep the area damp. This can cause redness, burning, itching, tenderness and superficial cracks. Folds under the breast, around the groin, beneath the abdomen and in the armpit are common sites. A secondary yeast or bacterial infection can change the rash, so home care should not be used to delay help when symptoms are severe or worsening.

Rinse with lukewarm water and a mild, fragrance-free cleanser if needed. Pat rather than rub, then allow the fold to air-dry briefly. Wear breathable clothing and change after sweating or exercise. Keep towels and clothing personal and launder them regularly. Do not apply perfume, essential oils, bleach, or strong antiseptics to broken skin. A thin protective barrier may reduce rubbing. If the rash has features of yeast, ask a pharmacist or clinician whether [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) is suitable rather than layering several products.

Contact a clinician if pain, warmth, swelling, pus, bad smell, open sores or fever develops, or if the rash extends beyond the fold. Get prompt help for rapidly spreading redness or severe tenderness. Repeated episodes deserve a review of triggers and possible [Skin Yeast Infection](/conditions/cutaneous-candidiasis/). [Intertrigo](/conditions/intertrigo/) and [Skin Rash](/symptoms/skin-rash/) provide useful background.

Is home care reasonable for this rash? Should I use a barrier or antifungal product? How will I know whether the skin is infected? Which sweat, clothing or activity triggers should I address?
