Methotrexate
"I have been a victim of psoriasis for the last seven years. I came to know about this drug from a skin specialist in the year 2004. Prior to this I was covered up to 75% but when I took this it vanished after taking a mere 30 mg. It recurred in year 2005. Since then I am taking it frequently, as I did not find any other alternative to fight this skin disorder. As far as my personal experience is concerned, I didn't have any side effect. "
