I am a nephro patient with high Cr and urea levels 90 & 3.8. I have been prescribed Renvela 800 mg twice daily. My phosporus levls in blood are normal as per report 5.6. Is it necessary to take renvela.  I have water accumulation in body after i sratrted taking renvela and was prescribed another pill to overcome that. Is it Ok???
Dear Patient, yes, it is safe because it is not absorbed, and it is not related with any side effect related with liquid overload. However, you must solve the edema, since it increases chronically the risk to develop cardiovascular diseases, and acutely blood hypertension and pulmonary edema. This is the number one priority. Take care.
