I'm on Actemra which works in a similar way as Kevzara. Both Actemra and Kevzara are IL-6 receptor blockers. My rheumatolgist said it takes about three months to feel the "full effects" of a biologic IF it is going to work. If a biologic doesn't work after three months then it might be time to consider trying something else.

I'm grateful the Actemra worked well for me. After being on prednisone for 12 years, I'm glad Actemra enabled me to taper off prednisone. It took me a total of 7 months to taper off the first time. I needed to go back on prednisone again for awhile. My Actemra dose was increased and I was able to taper off prednisone a second time. I have now been off prednisone for almost 4 years.
