Thanks for your responses!!!
The binder that my dad is on is TUMS. He receives hectorol and EPO at dialysis; he takes blood pressure medicines (Norvasc, Metropolol, and Avepro--not sure about the spellings!) and a baby aspirin every other day as well as a vitamin B supplement. He gets a vitamin B12 shot once a week and takes vitamin E every other day. His target weight was changed recently from 60.0kg to 60.5kg. He says that the fluid removed at each dialysis treatment is between 2000-3000cc/mg.
Thanks for any input you are able to offer.
