I am also a patient of Dr. Fosters. I started on Zenapax every two week on Oct 12, 2009 and continue on cellcept and neoral. Yeserday I was told we are going to start to cut back on the cellcept. I am a registered nurse working in an acute setting full time. I use "universal precautions" with all patients, and am probably slightly more cautious with pts known to be infected. I do, at all times, make sure our Infection Control Doctor is aware of my meds, and he alerts me if I need to be aware of any extra precautions needed.I hope this helps, when I first went on immunosuppresants I was petrified of exposures, but over the past year and a half have settled down with that....Lynn
