Anthralin may stain the skin, hair, fingernails, clothing, bed linens, or bathtub or shower. The stain on the skin or hair will wear off in several weeks after you stop using this medicine. Some ways to prevent or lessen anthralin staining include:
- Wear plastic gloves when you apply this medicine.
- Avoid getting the medicine on your clothing or on bed linens. Ask your doctor if you can wear a plastic cap while sleeping if you apply your medicine to your scalp at bedtime.
- Remove any medicine on the surface of the bathtub or shower stall by immediately rinsing it with hot water after bathing or showering. Afterwards wash the bathtub or shower stall with a household cleanser to remove any remaining deposits.
