Conventional treatment summary

Most will resolve on their own. If skin irritation is the problem then avoiding the irritant is all that needs to be done. If it is an allergic reaction then staying away from the cause should resolve the rash. Treatment includes medications to decrease the itching such as antihistamines like diphenhydramine (Benadryl). Diphenhydramine can be applied as a cream or taken as a pill. Topical steroids like over the counter hydrocortisone can be applied to the rash. More severe reactions may require stronger prescription only anti-itching medications like hydroxyzine (Vistaril) or oral steroids like prednisolone or prednisone.
