I guess if it work and how bad are side effect,

TYsarbi worked the best for me, but being positive for the JC Virus scared me and I am not going back on it unless I have too.

I got help to get the Tecfidera been on it for 7 days feels worst now than before don't sleep very well at night. Only side effects is little upset stomach I always take it with peanut butter. Hope it gets better.

I have been on Tecfidera for 9 months now. The only side effect I have experienced is occasional flushing. Sometimes the flushing is minor and other times it feels like a bad sunburn for around 30 minutes. The flushing is well worth not taking shots.

I am on Tecfidera for 4 months it messes with my stomach if I don't eat something when I take it.
