How To Use

Apply this medication using plastic gloves since fingernails may become discolored. Apply thin layer to the psoriasis lesion. Avoid the normal skin or scalp. Rub in well. For the scalp: wash hair first with a shampoo to remove loose scales. Rinse off the shampoo then apply medicine as directed only on the psoriasis area. Avoid contact with the eyes. At the end of the contact period (usually starts as 15-30 minutes per treatment) remove the drug by rinsing/shampooing scalp or washing, taking a bath or shower to remove any drug from skin. Wash hands after using this medicine. Treatment is usually continued until the affected area is entirely clear. The drug strength may be gradually increased depending on your response and tolerance.
