My concern is for the person paying 40.00 for renvela, speak to your socail worker...because if you have commercial insurance they can give you a 5.00 co-pay card that can be used at any pharmacy including mail order. Or you can go on line and google it an print one your self. You need to make sure the pharmacy has all the information on the card in order to get the help. If you don't ask the socail worker if there is any other help there often times is.
