What is Fosrenol?
Fosrenol prevents the body from absorbing phosphate, allowing it to be removed from the body.
Fosrenol is used to lower phosphate levels in patients with end stage kidney disease. High levels of phosphate can make it hard for your body to absorb calcium, which can cause serious medical problems.
Fosrenol may also be used for purposes not listed in this medication guide.
