Hi. Here is a pic (graph) from the Kevzara website regarding PMR. (Don’t be confused because it has RA Site in red at the top. That is to select the RA Site. This is showing the PMR Site.)

It shows a 14 week taper to zero, starting at 15mg/day, having taken Kevzara for 38 weeks (in combination with Prednisone) prior to beginning the final taper.

Left column is weeks.
At the top is:
CS dose mg/day.
(Corticosteroid-Prednisone.)

Basically, it says to taper 2mg per week until you reach 10mg/day.
At 10mg/day, reduce by
1 mg/ per week.
For 10 weeks.

Better yet, her is a link to that page on the Kevxara website.

Good luck and best wishes.
