After my first exacerbation in October 2007- when they changed my diagnosis to progressive relapsing MS- my doctor put me on Novantrone, which is a type of
chemotherapy. I had one dose every three months, and after I had a total of three doses, I weighed 98 pounds (I'm 5'6"), so we had to stop. I've been having steroid infusions since, and now I have one steroid infusion, once a month.
