Your doctor may prescribe an oral corticosteroid, such as prednisone. They may also give you a steroid cream to apply to your skin. If the rash becomes infected, you may need to take an oral antibiotic.
The available steroid over-the-counter or nonprescription is hydrocortisone (Cortizone-10®). Antihistamines, especially diphenhydramine (Benadryl®), are often used to help relieve symptoms associated with allergic reactions; however, the role of these agents in relieving symptoms of poison ivy are limited.
At night, the body's production of corticosteroids that reduce inflammation also slows down. It releases more cytokines at night, which increases inflammation. A combination of these two factors can make night itching worse.
