multiple sclerosis
"When I was found to have MS I was put on Rebif  for 6 months until Gilenya became available. The side effects on Rebif were severe.I was never able to eliminate them. After only 3 weeks on Gilenya, I couldn't believe how much better I felt. Not only were there no side effects noticed, but I actually felt better than I've felt for several years. It has noticably improved my life."
