Most contact dermatitis cases heal on their own, but if it is particularly itchy, a topical corticosteroid cream can ease the itch. Home remedies like oatmeal baths and cool compresses may also help. Over-the-counter hydrocortisone (a weak topical corticosteroid) is often insufficient; in these cases, you should see a healthcare provider. Oral steroids may also be prescribed if the rash does not respond to topical medication.
