It works by slowing down the growth of skin cells. This product does not contain a corticosteroid or coal tar. It is not meant to be used for a severe outbreak of psoriasis. Do not use this drug if the skin is inflamed or irritated.

This medication is for use on the skin and/or scalp.
To prevent discoloration of fingernails, apply this medication using plastic gloves.
Apply a thin layer to the area with psoriasis, usually once daily. Avoid the normal skin/scalp. Rub in well. If normal skin surrounding the treated areas becomes too irritated, you may cover the normal skin with petroleum jelly to protect it.
To treat the scalp, wash hair first with a shampoo to remove loose scales. Rinse off the shampoo, then apply this medication as directed, only on the psoriasis area.
Follow your doctor's directions for how long to leave the drug on the skin/scalp (usually starting at 10-30 minutes per treatment), then remove the drug. First, rinse with cool-to-lukewarm water (less than 80 degrees F/27 degrees C). Then, if you are treating the scalp, shampoo the scalp, and if you are treating the skin, wash the treated skin by taking a bath or shower using soap and hot water.
After using this medicine, rinse hands right away with lukewarm water, then wash with soap and warm water.
Do not allow the drug to come in contact with eyes, mucous membranes (e.g., lips, mouth, nose), or genital area. If this occurs, flush with plenty of cool-to-lukewarm water. If irritation occurs, contact your doctor right away.
