Dithranol

About Dithranol

Dithranol is applied to the skin to treat psoriasis.

Psoriasis is a skin disorder caused by cells in the outer layer of the skin multiplying too quickly. As new skin cells are produced, old ones are shed. If this process is taking place too quickly, old skin cells build up on the skin surface causing red, scaly patches. Dithranol helps to control psoriasis by slowing down the production of new skin cells.

Dithranol is available in cream, ointment, paste and scalp gel form. Your preparation may also contain other ingredients, such as coal tar or salicylic acid, to further help your condition.

Brands available are: Dithrocream; Micanol; Psorin.
