my husband is on kidney dialysis and is given Epogen and Heparin. He started dialysis on June 24, 2014. two weeks ago, he started getting a rash and kept getting worse and worse. Dialysis asked us to go to PCP who thought it may be Petechiae so he did a CBC ... came back normal. Thought husband may have an allergic reaction to Heparin given to him during dialysis. Stopped that for past two treatments; however, he is still getting red spotches and pimples now progressing to his whole body. Could he be allergic to the Epogen?
