I don’t have the same Autoimmune disease as you, but I have Lupus and Rheumatoid Autoimmune Disease. I have been having the Rituxin infusion for about five years. My Lupus is now in remission and my inflammation numbers are down. The thing about Rituxan is It is cumulative meaning it does not necessarily work after the first infusion. You get the infusions every 6 months. It took a couple of years before I really felt the difference in my body. Now when I get the infusion I can feel the positive effects within a couple of weeks. It is as though a vail is lifted off of me. It brings me quality of life.
I hope it works for you. 💓
