Sevelamer is used to lower high blood phosphorus (phosphate) levels in patients who are on dialysis due to severe kidney disease. Dialysis removes some phosphate from your blood, but it is difficult to remove enough to keep your phosphate levels balanced. Decreasing blood phosphate levels can help keep your bones strong, prevent unsafe buildup of minerals in your body, and possibly decrease the risk of heart disease and strokes that can result from high phosphate levels. Sevelamer works by holding onto phosphate from the diet so that it can pass out of your body.
Take this medication by mouth as directed by your doctor, usually 3 times daily with meals. Swallow the tablet whole. Do not crush, chew, or split the tablet. The dosage is based on your medical condition, any other medications you take to lower your phosphate levels, and your response to treatment. In children, the dosage is also based on body size.
If you are taking the powder form of this medication, check the manufacturer package directions for mixing with water, beverage, or food and taking it within 30 minutes. Follow the directions for the proper amount of water to use for your dose. Stir the mixture well and drink all of it. If the powder settles to the bottom of the cup, stir again right before drinking. You may also mix the powder with a small amount of food or beverage to take as part of a meal. If mixing with food or beverage, do not heat the powder or add to heated foods or liquids.
