My first DMD drug was
Tysabri and I have been on it almost 2 yrs, and was JC+ from the start.
Tysabri is very good at lowering relapses, but of course, does not correct anything already there.
You may continue to have relapses or attacks, it is not 100%, but does a good job. It is not usually a first drug, as you have been told, but your doctor had a good reason or he would not have put you on it
As Kyle said, let your doctor know…….
