Good evening, everyone.
I’ve been on Tecfidera since a bad injection site reaction whilst using copaxone. I’ve had a pretty good experience on Tecfidera, and whilst I’ve still experienced symptoms, they have been relatively minor and infrequent. I also had very few side effects. I have been switched onto the generic Dimeyhyl within the last month and wondered what other peoples experiences were? I’ve noticed that I seem to be having more frequent symptoms that are different in nature… I’ve also been getting really hot, bad headaches (sharp shooting pains that appear from nowhere), stomach problems, and acid reflux). I thought this was probably just all a coincidence, but I just wanted to see if any other people were finding similar? Thanks a lot.

Hi
I’m on vumerity,which is similar.
Biggest side effects I’ve had flushing of the face only lasts about an hour.
Recently really bad diarrhea,but I’ve got bowel and bladder issues.
I’ve been on vumerity since November 2023 had my yearly MRI my consultant was happy for me to continue with it, but as usual any changes contact Ms nurse
Hi, been on Tecfidera for 6 years. Switched to the generic versions a few months back. Made absolutely no difference at all.
I have very few side effects. The very occasional hot flush, but that’s about it.
Hi,
I was switched fromTecfidera to the generic version a couple of months ago & I’ve noticed a difference. Lots of hot flushes & sensory symptoms that I’ve not had as bad in years. Could be a coincidence but I’m going to chat it over with my MS nurse.

I’ve been on Tecfidera for the last 5 years and recently switched to a generic Dimethyl Fumerate. So far I haven’t noticed any difference really. Hopefully this continues to be the case 
Hi there yes i have been having side affects from the generic.
Awful reflux and flushing more, they saying no real difference but its not suiting me at all.
In contact with my ms nurse who has said to persevere. Has it got any better for you?
Hi I’ve been changed over and I’m only in my first week but I’m already experiencing sensory symptoms that are normally kept under control and also pains in legs I hadn’t had before, also feel the brain fog returning a little too.
