Tofacitinib
"Those who suffer with incurable rheumatoid arthritis understand the willingness to try a new medication that could possibly ease the painful symptoms of RA.  I tried Xeljanz hoping it was the limited cure-all. I've never paid too much attention to the commercial warnings as I am like many others that think, that couldn't happen to me.  We'll, it did.  I ended up hospitalized for several months diagnosed with e-coli sepsis.  In all fairness, this drug may be the one to help you.  Unfortunately, it wasn't for me.  Do take seriously the warnings that could develop while using this drug.  It CAN happen to you."
