It is day 7 since my infusion and I can’t get off the couch with exhaustion, woozy and nausea but joint pain and swelling almost gone

Ruxience is a biosimilar (generic) for rituximab. I have tried it. Sadly it did not work for me, but it may work for you. We all react differently to drugs.

I have never taken it so I looked it up. Do you take it for RA? Have you ever had infusions before? I know I can't do them. They do work for some people though. I would think being tired is a side effect. I know I was. It's a lot for our bodies to go through! Hopefully you will feel better soon.
