Can I treat Psoriasis with Flonase?
I am sorry but I have to tell you that there is no known cure for psoriasis. Your friend can tell you what he wants but it is incurable condition. There are remissions that can last really long (for a few years) but nothing final. Flonase can be used for treatment of psoriasis in shape of cream especially made for that purpose, but it only can ease the symptoms not cure it.
