Acitretin is used to treat severe skin disorders, such as psoriasis. It works by allowing normal growth and development of the skin. Acitretin will continue to work after you stop taking it, but after a time, the skin condition returns and you may need to take it again.
Acitretin must not be used to treat women who are able to bear children unless other forms of treatment have been tried first and have failed. Acitretin must not be taken during pregnancy because it causes birth defects in humans. If you are able to bear children, it is very important that you read, understand, and follow the pregnancy warnings for acitretin.

However, if dry mouth continues for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of developing dental disease, including tooth decay, gum disease, and fungus infections.
