I went from Copaxone to Rebif and have now moved to Ocrevus (twice a year infusion). I am waiting for my first MRI since switching to it so am uncertain if there are new lesions but I don’t think so.
My neuro usually gives me a short list of options and I research them and come up with a preference. This group always has great suggestions and I check through the playlist on Dr Boster’s You Tube channel- https://www.youtube.com/playlist?list=PL3a4GpjWLtCjzcJzGEcQC0Z3S4xGA-vaM
You can also put any of the DMTs you are considering into the little magnifying glass in the upper left to find discussions on it-
