Hi @karlsohare, I believe (correct me if I’m wrong) that these types of drugs are supposed to reduce the number of relapses once you’re on them. I was on Copaxone for a few years and it kept me pretty well but that’s the thing you don’t actually know totally how it’s working but every time I’ve come off DMTs bang I’ve ended up relapsing (like right now as I came off my Extavia for a few weeks). I hope this helps a bit but time will tell when relapses are lessened or don’t happen so often or indeed at all. ⭐️Loo

I agree with @look rather than making us better they are supposed to slow down the rate at which we decline so it's a bit difficult to judge how much of an effect they are having. I've been on Tecfidera for 2 years now and I haven't had a relapse in that time, if I would have had one without taking it or not is impossible to tell, I assume that it's working but maybe it's just a coincidence and I wouldn't of had a relapse anyway. The only thing you can really judge is if it's not working, if you're taking a DMT but still declining/having relapses then it's clearly not working for you but if you haven't had any new symptoms/relapses then you can only assume it is working (although there's no way to know for sure if that's down to the DMT or not). If you're feeling quite well then long may it continue :)
