Q: What is Sevelamer used for?

Sevelamer is used to treat hyperphosphatemia in chronic kidney disease .

Q: How does Sevelamer work?

How Sevelamer Works Sevelamer belongs to a class of medications known as phosphate binders. It is used to manage phosphorus levels in people with chronic kidney disease who are on dialysis. When the kidneys are not functioning properly, they cannot effectively remove phosphorus from the blood, which can lead to serious health complications. The medication works through the following process: Binding in the Digestive Tract: Sevelamer is a polymer that is not absorbed by the body. When taken with meals, it stays within the stomach and intestines, where it attaches to the phosphorus found in food. Blocking Absorption: By binding to the phosphorus, the medication prevents the mineral from passing through the intestinal walls and entering the bloodstream. Elimination: The bound phosphorus remains trapped with the medication and is eventually passed out of the body through bowel movements. By reducing the amount of phosphorus absorbed from the diet, sevelamer helps maintain a healthier balance of minerals. This process also helps prevent the body from pulling calcium out of the bones and reduces the risk of calcium deposits forming in the heart, lungs, and blood vessels.

Q: Is Sevelamer safe during pregnancy and breastfeeding?

Pregnancy There are no adequate and well-controlled studies of sevelamer use in pregnant women. Because the medication is not absorbed from the digestive tract into the bloodstream, it is not expected to reach the developing fetus directly. However, sevelamer can bind to and decrease the absorption of certain nutrients that are vital for fetal development, including: Folic acid Vitamin A Vitamin D Vitamin E Vitamin K If you are pregnant or planning to become pregnant, discuss the potential risks and benefits of this medication with your healthcare provider. They may monitor your vitamin levels or recommend supplements if sevelamer is necessary for your treatment. Breastfeeding It is not known whether sevelamer passes into human breast milk. Because the drug is not absorbed into the mother's systemic circulation, it is unlikely to be present in breast milk or to pose a direct risk to a nursing infant. As with pregnancy, the primary concern is the medication's potential effect on the mother's vitamin levels. Consult with a healthcare professional to determine if sevelamer is appropriate while breastfeeding and to ensure adequate nutritional intake for both mother and child.
