These are the medications I have been able to discontinue after Actemra was started. Prednisone was the first medication to go. All the other medications were stopped over a period of 4 years after Prednisone was discontinued.

PREDNISONE 10 MG TABLET DAILY
ATORVASTATIN 40 MG TABLET DAILY
LOSARTAN 100 MG TABLET DAILY
AMLODIPINE 10 MG TABLET DAILY
SPIRONOLACTONE 50 MG TABLET DAILY
WARFARIN 5 MG TABLET DAILY
METFORMIN 500 MG TABLET 2 TIMES DAILY
RANITIDINE 300 MG TABLET DAILY
CHOLECALCIFEROL (VITAMIN D3) 2,000 UNIT TABLET DAILY
TIZANIDINE 4 MG TABLET 3 TIMES DAILY-- as needed

Everyone is different. Since PMR started a year and a half ago, I have halved the dose of my two blood pressure meds - metoprolol and atacand. My blood pressure, which was still fairly high even on the higher dose, has dropped to normal while on prednisone. I have dumped the statin without any worsening of tryclyceride etc levels.

For me, the health improvements and ability to drop those meds while on prednisone were due to eating low carb/sugar and cutting out processed foods and additives. For some people, maybe it's the prednisone, for many of us it's improved diet and increased activity.
