Hey Swon, my infusion nurse told me it takes up to 5 months for orencia to work at all. It was exactly 5 months before I noticed any difference, if you were only on it a few months you hadn't given it long enough to build up in your system. It accumulates very slowly. Having said all that it never worked as well as humira has fo me. Plus I got a lot of mouth ulcers on it.
But just in case you didn't know.
Regards, golitho
