I'm still waiting for some answers to my question on how long does Rituximab take to work. I've been waiting over ten week without any success, any advice would be gratefully excepted. God bless you all. One more thing I would like to mention I've been in so much pain since I started this drug, they've given me steroid injection and tablets but refused to give me any more. I'm at my wits end. Seeing the Rhumotolist on the 04 /05/17 can't wait. I just wish they could be more understanding towards this illness.
