Leflunomide
"I was prescribed leflunomide for Psoriatic Arthritis, 20mg each day, in May 2012. For the actual treatment of my arthritis, I can honestly say it was a "wonder drug" I noticed a huge improvement all most immediately & this drug agreed with me so much more than Methotrexate & Sulfasalazine, both of which I had also been taking.

The biggest negative for me was the HUGE hair loss I suffered. I had experienced some hair loss on Methotrexate, but, this was on a different level, so much so that I stopped taking Leflunomide in November 2012. 

Being a female in her early 40's, this was a decision I felt I had to take as the hair loss was so distressing."
