Treatments for skin rashes include oral medications and medicated creams, according to the National Institute of Health. Skin surgery is also a solution for some skin rashes. The treatment depends on the cause of the problem.
While a primary care provider can handle common skin rashes, a dermatologist should handle more complex cases, says the National Institute of Health. Oral medications that can treat skin rashes include antihistamines such as diphenhydramine and hydroxyzine, according to MedicineNet. Topical antifungal medications that are rich in substances such as clotrimazole, terbinafine and myconazole are suitable for treating skin rashes caused by fungal infections. Effective creams include those that fight itching and have 1 percent hydrocortisone content.
