Overview
Renvela 800mg Tablet contains sevelamer carbonate 800mg, a non-calcium phosphate binder used to control high blood phosphate (hyperphosphataemia) in adults with chronic kidney disease, including patients on dialysis and some who are not yet on dialysis.
Sevelamer works by binding to phosphate from food within the digestive tract, forming a complex that is not absorbed and is eliminated in the stool. This reduces the amount of phosphate absorbed into the bloodstream, helping to keep blood phosphate levels within a healthier range.
How it Works
Sevelamer carbonate is a non-absorbed polymer that binds dietary phosphate ions within the gastrointestinal tract, forming a complex that passes through and out of the body in the stool rather than being absorbed. By reducing phosphate absorption, it helps lower elevated blood phosphate levels associated with chronic kidney disease.
Directions for Use
Renvela 800mg Tablet must always be taken with meals or substantial snacks, as it works by binding phosphate from the food you eat – it will not work effectively if taken on an empty stomach. Swallow the tablets whole with plenty of water; do not crush, chew, or split them, as they are large tablets designed to be swallowed intact.
Dosage
The dose of Renvela 800mg Tablet is individualised based on your blood phosphate level and whether you are on dialysis, typically taken as one or more tablets three times daily with meals. Your doctor will adjust your dose based on regular phosphate level monitoring.
