Medicines for Intertrigo

What it is

Intertrigo is inflammation of the skin in body folds — such as under the breasts, in the groin, the armpits, the tummy folds, and between the toes — caused by skin rubbing against skin in a warm, moist environment. The friction, trapped sweat and lack of air breakdown the skin, causing a red or discoloured, sore, sometimes itchy or stinging rash, which can become cracked, weepy or smelly. Because the warm, moist folds are an ideal environment for microbes, intertrigo is frequently complicated by infection — often a yeast (candida), and sometimes bacteria — which adds to the redness, soreness and any discharge or odour. It is more common in people who are overweight (with deeper folds), in warm or humid conditions, with sweating, diabetes, reduced mobility, or incontinence. It is uncomfortable but manageable, and identifying and treating any infection is an important part of care.

How it is treated

Management focuses on reducing the friction and moisture that cause the problem, and treating any infection. Key measures include keeping the affected folds clean and dry — gently washing and thoroughly drying (patting, not rubbing), and allowing air to the area where possible — and reducing friction and moisture (for example with loose, breathable clothing, and sometimes barrier creams or moisture-absorbing measures). Where infection is present, it is treated: an antifungal cream for a yeast infection (common), or an antibacterial treatment for bacterial infection, and sometimes a short course of a mild anti-inflammatory treatment to settle the inflammation. Managing contributing factors — such as weight, blood sugar in diabetes, sweating, and incontinence — helps prevent recurrence, which is common. If it is severe, widespread, not improving, or the diagnosis is uncertain, a doctor can advise. The reassuring message is that intertrigo is manageable with good skin care and treating any infection, though it can recur if the underlying factors remain.
