Sorry, no experience with Kezvara. My story in brief: Diagnosed with PMR in August. Started pred at 25 mgs. in the morning. No help. Bumped to 25. No help. BUT, then I learned that people were splitting doses, which my docs sort of reluctantly approved. Half in morning and half at night gave me huge relief right away the next day. Been tapering by 2 mgs every two weeks since then. Now down to 12 per day and will slow down further by tapering by one meg per month soon. So far so good. Following this helpful thread, everybody seems to agree a very, very slow taper is best. Good luck!
