Ocrevus.. do you recommend it?

I am wondering if you would recommend ocrevus? It’s a newer med and i don’t like that because it’s hasn’t been around that long and I also don’t like that it will take away your immune system. What does someone do when they need surgery and has no immune system left to fight off the infections? I was given the choice copaxone or ocrevus. The doctor basically said we can try copaxone and if you have no new lesions in a couple months you can stay on it but if you get lesions then start infusion of ocrevus. I guess I’m just really scared

edit thank you everybody for being kind with your answers. This is all new to me and I’m really really scared. I guess I’m also scared because I also have something called Alpha gal syndrome. so I can react to things more so than other people. just like right now I’m not on any medication but every time I get my period my goes haywire and I start getting sores all over my lips, horrible migraines. My immune system just feels really depleted so I was worried that if I try the infusion. It will only make me worse in regards to my immune system***
