What should you know about erythema intertrigo treatment?

The right approach depends on whether moisture and rubbing are the main problems or whether yeast, bacteria, eczema, or another condition is involved. A fold can be red and tender without needing an antifungal medicine. If the skin is moist, has small surrounding spots, or keeps returning, a clinician may examine it for yeast; [Skin Yeast Infection](/conditions/cutaneous-candidiasis/) explains that related problem.

Clean gently, pat dry rather than rubbing, and allow air to reach the fold when practical. Wear breathable fabrics, change damp clothing, and use a clean, dry cloth or prescribed barrier to reduce skin-on-skin contact. Use [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) only as directed when a clinician identifies a fungal component. If sweating drives recurrence, ask whether [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/) is suitable.

Book an appointment when home measures do not improve the rash, symptoms recur, or the fold becomes cracked, wet, crusted, or painful. Get urgent care for rapidly expanding redness, severe pain, fever, pus, marked swelling, or new illness. These signs need assessment for infection rather than repeated self-treatment.

What is causing this fold inflammation? Do I need an antifungal, antibacterial, steroid, or barrier product? How long should I use it, and how can I prevent the next flare?
