Suggest Treatment For Severe Itchiness All Over The Body

Yes, my husband is on dialysis with Davita in Sandusky Ohio. He has been having terrible itching all over his body since he started taking fosrenol, he is not real happy with the doctors there, his first question is, is there something else he can take to get rid of this terrible itching, and next question is does he have to use the doctors they have their or can he go back to his other kidney doctor once a month? thank you
