Product introduction
Fosbait 250mg Tablet is used to control the levels of phosphate in the blood of adult kidney failure patients on dialysis
Uses of Fosbait Tablet
Benefits of Fosbait Tablet
High phosphate levels in blood
High phosphate levels in the blood (also known as hyperphosphatemia) commonly occur in people with chronic kidney disease, where the kidneys are unable to properly filter out excess phosphate. Fosbait 250mg Tablet is used to manage this condition. It helps by binding to phosphate from food in the digestive tract, preventing its absorption into the bloodstream. This helps maintain healthier phosphate levels and reduces the risk of complications related to bone and heart health.
