Hi, Copaxone (glatiramer) is indicated in RRMS (Relapsing remitting multiple sclerosis). Flushing is one of the common side effects of this medication. If you are able to tolerate it and also with mininimal flare ups, I see no reason for a change in medication. But if the side effects are severe and intolerable and flare ups are occurring more frequently, then you can opt for the new medication. I would suggest you to have a discussion with your neurologist about the choice of medications and then decide. I hope the above information helps you. Thanks for writing into healthcaremagic. Have a wonderful day.
