@jlk1323 I had 4 rounds of rituxan for an autoimmune inflammation 0f my brain. I felt like a new person after the 1st 2 rounds ( over 12 months), but the 3rd and 4th rounds didn’t help at all. Some people react positively to the drug, others not. I then switched to cytoxan, which was difficult but it was only 8 months. Every single person is so different! I felt so much better after the 2 rounds of rituxan, that we went ahead with our trip to Europe. Pre-Covid, of course!
Your doctor may be non-committal because he /she wants to see how you tolerate the drug and how well it works for you. It would be well worth another chat with him/her.
My brother=in=law sent these articles to me. (He’s a pharmacologist/toxicologist). This article compares rituxan to oral drugs, but it does have good information

Are you seeing a rheumatologist for treatment?
