Acitretin

Why this is used

Acitretin is used to treat severe psoriasis (abnormal growth of skin cells that causes red, thickened, or scaly skin). Acitretin is in a class of medications called retinoids. The way acitretin works is not known.

How to take it

Acitretin comes as a capsule to take by mouth. It is usually taken once a day with the main meal. Take acitretin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take acitretin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Your doctor may start you on a low dose of acitretin and gradually increase your dose. Acitretin controls psoriasis but does not cure it. It may take 2-3 months or longer before you feel the full benefit of acitretin. Your psoriasis may get worse during the first few months of treatment. This does not mean that acitretin will not work for you, but tell your doctor if this happens. Continue to take acitretin even if you feel well. Do not stop taking acitretin without talking to your doctor. After you stop taking acitretin, your symptoms may come back. Tell your doctor if this happens. Do not use leftover acitretin to treat a new flare-up of psoriasis. A different medication or dose may be needed.
