@jodipat77 I'm glad your daughter's RA is controlled enough to taper the prednisolone, but after so long using it, her body is struggling to catch up. When she was first tapering from larger amounts, the %age reduction with each step down was less than now on lower doses. Perhaps a more gradual taper, like going from 2mg to 1.75, then 1.5, etc would be easier for her body? It will require pill cutting or shaving to get the lower dose, but might be easier. My friend with another autoimmune disorder was never able to go below 2mg without major flaring. Your daughter may have to resign herself to staying on a very low dose.
When I taper prednisone, I must remember to stay very well hydrated and often need short term pain relivers in addition to my RA meds.
Does her doctor support fully stopping in spite of her side effects?
