Self-care * If blistering develops, cold moist compresses applied for 30 minutes, 3 times a day can offer relief. * Calamine lotion may relieve itching. * Oral antihistamines such as diphenhydramine (Benadryl, Ben-Allergin) can relieve itching. * Avoid scratching. * Immediately after exposure to a known allergen or irritant, wash with soap and cool water to remove or inactivate most of the offending substance. * For mild cases that cover a relatively small area, hydrocortisone cream in nonprescription strength may be sufficient. * Weak acid solutions (lemon juice, vinegar) can be used to counteract the effects of dermatitis contracted by exposure to basic irritants. * A barrier cream, such as those containing zinc oxide (e.g., Desitin, etc.), may help protect the skin and retain moisture. Medical care If the rash does not improve or continues to spread after 2–3 of days of self-care, or if the itching and/or pain is severe, the patient should contact a dermatologist or other physician. Medical treatment usually consists of lotions, creams, or oral medications. * Corticosteroids. A corticosteroid medication like hydrocortisone may be prescribed to combat inflammation in a localized area. It may be applied to the skin as a cream or ointment. If the reaction covers a relatively large portion of the skin or is severe, a corticosteroid in pill or injection form may be prescribed. In severe cases, a stronger medicine like halobetasol may be prescribed by a dermatologist. * Antihistamines. Prescription antihistamines may be given if non-prescription strengths are inadequate.
