Unfortunatly Federal Law makes it illegal to give any prescription medication to another person . That is absolute.
I've given UNOPENED extra bottles of Renvela, Fosrenol and other meds like Calcitriol (all with personal labels removed) to dialysis center dietitians. They only distributed to patients in need who had been prescribed those meds. It does help a lot. I benefited in the past by getting cyclosporine from other patients when not being able to afford it. Yes, there are rules and regs, but many know the times when heads can look the other way. Our disease, and its delivery isn't always a black/white situation. At times, humanity trumps regulations.
