Hi Allen. Sorry this is happening to you. Don't know about cellcept, but prednisone can contribute / induce high glucose in some people too.

How high was your glucose, did they do a Glucose Tolerance Test (GTT), and have they given you any medication . . . or are they trying dietary and lifestyle changes first? If your fasting glucose levels are not too high - this may very will be controlled by dietary and lifestyle changes. Not easy..but doable.

Please take care and let us know how you are doing.
