This medication is used on the skin to treat the
itching, scaling, and flaking due to skin conditions such as psoriasis or
seborrheic dermatitis. Coal tar belongs to a class of drugs known as
keratoplastics. It works by causing the skin to shed dead cells from its
top layer and slow down the growth of skin cells. This effect decreases
scaling and dryness. Coal tar can also decrease itchiness from these skin
conditions.
