Natalizumab
"I've only had 2 infusions of Tysabri so far.  My Dr. is planning on keeping me on the drug for 12 months.  So far, the side effects are min.  a migraine headache and extremly tired.  BUT those I can certainely live with.  Within 1 day after infusion they are gone.  This drug so far is much better.  I seem to be feeling better both mentally and physically.  I wish this drug was the first drug that I would have been given 13 yrs ago -- maybe then I would not have been classified disabled and still be able to work."
