How should I use coal tar?
Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Apply coal tar cream, lotion, ointment, or solution according to the directions on the medication label. Some forms of coal tar may be applied 1 to 4 times per day.
To use coal tar bath oil, pour 1 to 3 capfuls into a warm bath before bathing. The oil can make the bathtub slippery. Take care to avoid a fall.
Shake the coal tar shampoo well just before each use. Use enough shampoo to create a rich lather. Massage the shampoo into your scalp and rinse thoroughly. Apply the shampoo a second time and leave it on your scalp for 5 minutes. Rinse thoroughly.
Coal tar shampoo may discolor blond or colored hair. This effect is usually temporary.
Do not use coal tar to treat large skin areas. Do not use coal tar over long periods of time without your doctor's advice.
Some forms of coal tar can stain fabric or other surfaces.
Call your doctor if your symptoms do not improve, or if they get worse while using coal tar topical.
Store at room temperature away from moisture and heat. Keep the medicine tightly closed when not in use.
