multiple sclerosis
"First, it's not a shot!  Second, side effects are easily controlled  (eat something with some fat content, take allergy med and baby aspirin before taking Tecfidera).  If side effect occurs (flushing) it goes away quickly  (15 mins or less).  I was on Rebif before, and changed to Tecfidera about a year ago.  Have seen no lesion activity in last few years (MRIs)."
