@dd11 , try selecting the "Tecfidera" tag that has been automatically added to the foot of your post above. This will locate the previous conversations about Tecfidera.

The side effects are 'on the side of the box' Stumbler has already given you the info on Teccy speech on this site, we all react differently but the basics are low dose for 2 weeks, flushing and itching within 1/2 hr of taking dose, full dose after 2 wks, bad tum for a couple of days in wk 3/4 but we do have some users where this is ongoing several months later, most side effects settle down after 8 wks, and as a rule all is plain sailing from there. On this site we gave quite a lot of starters like you, some like me have been on it for just over a year, some have been on it for several years. Lots of experience, some people take an asprin, some an anti-histamine etc., read all you can, don't worry about it, and your ms nurse us always at the end of the phone if you need any more help!😜👂
