Briumvi / Tecfidera

Well, after an 8 year run on Rituxan, I had a crazy allergic reaction (the reaction was actually to Truxima, because my stupid insurance made me switch to the generic, and insisted I wouldn't have an issue), but I did, and it wasn't great. So now, my doctor is recommending either Briumvi (since I do well on the b cell therapy), or tecfidera. Years ago, I was on Gilenya, so going back on pills is not really something I want to do, but I also know infusions can suck too. Has anyone gone from Rituxan to Briumvi? Is it similar?
