Intertrigo rash treatment

The focus of treatment is on the prevention of things or circumstances that predispose the person to intertrigo rash. The use of prescription medication is rare. Intertrigo treatment management mostly involves home treatment and natural remedies, which include the following:

• For inflammation and itch, a mild topical steroid cream is used.
• For severe itching, the doctor might recommend antifungal medications.
• Wear breathable clothing to promote air circulation and prevent moisture buildup.
• Apply drying agent such as powder containing cornstarch.
• Itching sensation can be alleviated by applying a cold compress.
• Apply virgin oil to the affected area to retain the moisture of the skin and prevent scar formation.
• Itching and irritation can be reduced by simply applying aloe vera extract. ^{(8, 9, and 10)}
