Editing to add- I completed my second round of treatment in 2020, and had some mild side effects but now it is out of my system, my lymphocytes are at a ”normal” level, and I’m being considered stable! Hi all! I’m looking into changing from Gilenya to Mavenclad, and I’m just a bit confused! I’m seeing my MS nurse in a month to tell her what I’ve decided but I was just hoping someone here could help answer some questions in the meantime!    I originally really wanted Lemtrada, even though the side effects were a bit daunting, the possibility of it reversing some damage sounded so promising. But, I know that’s not a guarantee and it’s just not an option for me, so here we are.    I think Mavenclad could be a good idea for me, but I was wondering, I know it will lower my white blood cell count like the other medications, but once a it’s worked it’s way out of my system, does that come back up? Or does it suppress it long term since that’s what supposed to be helping the MS. I’m just confused because it says after 6 months it’s out of your system!    I’m also a bit nervous of side effects, while probably milder than some medications, once you take it there’s no stopping if things go wrong. That makes me a bit worried!    Any feedback would be appreciated, I know this medication has been posted about before but I didn’t see anything talking specifically about white blood cell count and how people feel long term, side effects wise.  Thanks!
