Typical start dose is 15-20 mgs. for PMR. Much higher for GCA. Your objective should be to reduce to the point where you feel good. We all want to get to zero, but the disease lets us know how fast and far we can go. Speaking of fast, at this point, slow is better...dropping by no more than 10% and then only when you are stabilized in terms of pain. If I were you I'd stay at 10 if the pain isn't too bad. If it's bad, you may need to go to 12.5 and see how you do. If that's better, stay awhile and then reduce very slowly. By the way, I'm sure most of us can relate. I felt great at 15 mgs., but struggled below 10. I'm back up to 10 now and will try again reducing to 9.5. Slow and easy.
