Avoid triggers that can make your symptoms worse, such as wool, lanolin, and certain foods. Do not take frequent baths. Excess bathing and soap can cause dry skin, which often makes the condition worse. Also, avoid hot water while taking a bath or shower.
Your doctor may recommend skin lotion that repairs the barrier of the skin, special skin cleansers that are mild, or moist bandages to soothe scaly, dry, or healing areas. Antihistamines may be prescribed to relieve itching.
Persons with severe symptoms may be prescribed ointments that contain tar, corticosteroids, or other medicines that lower the immune system. In very severe cases, more powerful medicines called steroids are prescribed. These may need to be applied to the skin or taken by mouth.
