So I have recently had to stop taking Tysabri due to a developed allergy to the medicine. I have taken Rebif, Copaxone, and Tecfidera, which have all been either resisted by my body or were simply inefficient. I am 18 years old and am currently looking for another medication. My options right now are to try Lemtrada, (the side effects and toll it takes on one’s body terrifies me), wait for that one medicine to be approved in March, but not available until probably around Fall time, or to take Gilenya. I have read all of the studies on this pill and the risk of slower heart rates, but this pill doesn’t sound ALL that bad. Could anyone tell me their experiences with Gilenya?
