ive got severe rheumatoid arthritis, ive tried numerous drugs over the last 10 years. now im on infusions. I started with Retuximab = no change, then was put on Toxcillimab infusions = no change EXCEPT I put on 3 STONES in weight in 6 months while having them, then went to see my consultant only to be told that these infusions can make you put on weight, which I wasn't told in the beginning !!! I am now back on 8 Tramadol and 4-6 co dydramol daily and 2oomcg of Fentanyl again just to help with the extra pain on my joints of carrying this extra weight around. I am very unsure now because ive been told that ive got to start a new infusion in 2 weeks of Abatacept and I cant find much info on it because its a new drug. Please Please can anyone give me any information, because I cant put anymore weight on. Sorry to waffle on, but im starting to feel like a Guinnea Pig for the specialists. kind regards, Dee.
