The ones i have seen most frequently are higher cholesterol which is similar to what Prednisone does and a higher than normal WBC, The biggest issue appears to be cost if your insurance doesnt cover. If you have GCA Actemra is shown to be better. The idea is to keep your PMR from flaring back up due to the prednisone taper. This will not help with cortisol production. Methotrexate is old standby but it has a lot of issues as well. Some others i have seen are Humira and LDN. LDN intrigues me. But I dont know much about any of them. Hopefully you dont need to take it forever to get off the the prednisone. I think they all have some side effects.

Drugs.com has an excellent summary of possible side effects from Kevzara. In my case low WBC and I had to come off of it. My PCP prescribed for me and yes a blood test is required to rule out TB. I had great results until I had to stop.
