I was on Kevzara for 8 months for PMR. It did help PMR symptoms but didn't allow me to reduce the prednisone below 5MG. The side effects I had were cholesterol going up 50 points and white cells dropping to below normal. I had to get off the drug due to cost and the cholesterol and white cell counts went back to normal within a few months. I was offered Actemra by my doctor and hesitated since it is a similar drug and I thought the side effects might be the same. My primary care doctor encouraged me to go on Actemra, telling me that the cholesterol rise I had was not bad enough for me to need a statin and I would probably not be on the drug that long, so I am now on Actemra.
