What are acitretin capsules?
Acitretin capsules are a medicine used to treat severe forms of psoriasis in adults. Psoriasis is a skin disease that causes cells in the outer layer of the skin to grow faster than normal and pile up on the skin’s surface.

Acitretin capsules may not work right away. You may have to wait 2 to 3 months before you get the full benefit of acitretin capsules. Psoriasis gets worse for some patients when they first start treatment with acitretin capsules.
