Having a nephrologist you see regularly is important. I see my local nephrologist every 4 months. Soon I'll be on once a year with the transplant center. The transplant center does prograf, cellcept, prednisone, and omeprazole. They determine any changes to those meds. My local neph does everything else. BP meds, osteoporosis, cholesterol, etc. It actually works well.I have no idea why that doc would be so mad about not being able to change your prograf. He was way out of line. Keep looking for a new doctor to see regularly.
From the time starting dialysis going forward - even when I had a transplant - I've been fortunate to have nephrologists also taking on the role as my PCP. Works great for me since they all have internal medicine practices with nephrology as their sub-specialty. Much less complicated without an additional MD in the loop, especially when medical records are involved and needing a referral to another specialist.
