Good question. My rheumy started me on 15mg for 5 days but wasn’t strong enough (6-7 out of 10) then upped to 20mg for 2 weeks then back to 15mg for 2 weeks, now on 12.5 for 2 weeks. Same as someone else, I have some pain/stiffness (3-4) for a 5-6 days then seems to get better (my body’s adjusting?). My regimen will be 2.5 tapper every 2 weeks going forward until I get to 5mg? I would definitely talk with your doc re when to go back up or down and if it’s ok to be at pain level 4 for a few or so days to see how your body does. Good luck
