I am on Peritoneal Dialysis. Have been experiencing going Phosphorus above reference range. Shooting up from 4 to 5 to 6.5 to 7.6 since OCT'16. Increased Ca Acetate to 12 caps/day. Just wondering what could Renegel or Fosrenol or Renvela do as a supplement to Ca Acetate. I understand Renela is not typically approved by most insurance cos. Out of pocket expenses too high. That's why talking about a supplental drug.
