Tecifdera is kind of special to me. Not that I’m on it. I almost switched from Tysabri to Tecfidera under the great Dr. K’s suggestion. He cited that there was no reported PML cases (at the time) as the reason for wanting me to switch. Boy, I am seriously glad I did not make that switch.
Dr. K said, if you recall from earlier posts, Tysabri is seen to have ~80% effectiveness at reducing exacerbations (100% in my case). Whereas Tecfidera has only ~50% effectiveness at stopping flare-ups. Plus Tysabri is, I assume, engineered in a lab in a far away land. While you can see train cars going by filled with Dimethyl Fumerate. Yet they charge almost as much as Tysabri for it. Probably because of drug testing/safety and whatnot, but it just doesn’t seem right how much they charge for MS medications when they roll by en mass on a train…but that’s another post.
So yeah, the big point that was turning me on to Tecfidera is that it’s a pill. No needles…sign me up! Except for that lost efficacy. And it turns out that there is PML risk with Tecfidera too…perhaps from earlier drug interaction? I’m not exactly sure. Not to mention the other side effects Tecfidera can cause. I am just glad I did not make that switch. Seriously glad, as greater effectiveness plus once-every-two-months dosing isn’t that bad…even I could deal with the needles that infrequently. And I mean it, Tysabri is working like a charm for me. So I stuck with what I know, and I am very happy with that decision…thus far.
And it isn’t the last alternative I’ve been offered, which of course I’ll try to get to in the next post.
