Intertrigo is a common skin rash seen in skin-folds like the armpits, beneath the breasts, genital area and abdomen – in infants it can show up as diaper rash. Typically, it presents as a pink-red scaly rash that may be itchy, cracked or oozing with a foul odor.
Friction between skin folds and trapped moisture and heat are common triggers for this inflammatory skin reaction.
For infants it is recommended to keep the area dry and exposed to air as well as apply a barrier cream to protect the skin.
To treat the intertrigo, short-term use of a topical steroid can reduce inflammation in the area. If in addition to inflammation the area is infected, your doctor may prescribe an antifungal or antibiotic ointment, and in some cases an oral treatment.
