By Mayo Clinic staffThe best treatment for diaper rash is to keep your baby's skin as clean and dry as possible. If your baby's diaper rash persists during home treatment, your doctor may prescribe an antifungal cream or possibly a mild hydrocortisone cream as a diaper rash treatment.
Diaper rashes usually require several days to improve and can continue for weeks. If the rash persists despite prescription treatment, your doctor may recommend that your baby see a dermatologist.
Use creams with steroids only if your baby's pediatrician or dermatologist recommends them — strong steroids or frequent use can lead to additional problems.
