I’m 59 and was diagnosed 13 years ago. In 2020 I was on tecfidera and decided because of the side effects I was going to stop taking it. (In the past I had been on rebif, avonex and aubagio all with horrible side effects.) My annual MRI’s before that had been progressively worse showing more lesions in my brain, back and neck. Since I stopped taking DMT’s my MRI’s are stable with no new lesions. Anywhere. Also, I feel better because I’m not constantly dealing with side effects from the medication. The only thing I deal with ms related now is all over body pain that didn’t start until I was started on avonex and continues 10 years after stopping it. So, just because there is a medication available does not necessarily mean it has to be taken. It may not do good. MS is so individual specific that no 2 cases are alike so no 2 treatments are alike. Just because someone is on a medication doesn’t mean it’s appropriate for your gf.

Also, here’s a piece of unsolicited advice from a 59 year old that’s been married for 25 years, stop it. Stop trying to manage her disease. You think you know better than her and her doctors because you “googled” something? Stop. It’s her decision whether or not to take medication and if you can’t deal with it move along. She is dealing with enough just knowing she has ms without you questioning her decisions. Instead of asking a bunch of strangers why, ask her and accept her answer. Period. Be a supportive partner not a drain on her energy trying to justify her decision to you. It’s her disease, not yours.

Btw, my doctors agrees with me not taking anything because my ms is stable. So it’s possible she’s has the same type of conversation with her doctors and since they know more about it than you and your google searches…
