Hello everyone I recently had my labs done about two weeks ago, and my creatine level was stable. My creatine level went up recently after my labs showed a high level of Tacrolimus which was 9.1. I retested last week after my doctor lowered my dose. My creatinine stayed the same but my Prograf level went down to within range to 5.1. How long does it take for your creatine to go down after a high-level the Prograf was in your system.Any advice, I’m a little worried.
