Advice & Tips: This treatment had virtually no negative impact on me, with the exception of developing post-transplant lymphoproliferative disorder (lymphoma) over thirty years later. That nearly killed me, but five years passed and I am declared cured, and 37 years after my transplant, my kidney still works well.

Advice & Tips: Taking two or three pills for life off of dialysis is a no-brainer. I developed lymphoma as a result of the azathioprine, but the chances of getting this are greater for the newer medications. I was initially worried about infections from this med but it has not been much of a problem.
