What is Renvela used for?

Renvela is used in addition to dialysis to help lower blood phosphorus levels in those with severe kidney disease. Decreasing phosphorus in the blood stream when levels are too high can help reduce the risk of weakened bones and may also help prevent heart disease and stroke.


How does Renvela work?

Phosphorus enters into our bodies through the food we eat which then gets absorbed into our blood stream. Renvela contains Sevelamer Carbonate, a phosphorus binder, which has the ability to bind to phosphorus. Once it binds to the phosphorus, it cannot be absorbed into the blood stream, resulting in a lower level of blood phosphorus.

It is important to take this medication by mouth, swallowing the tablet whole without crushing, chewing, or splitting the tablet in half. It is generally taken 3 times per day with food; however, your doctor will prescribe this medication to you with a specific dosing regimen, including what strength to take, how often to take it, and if you can take it with food.
