Used to treat or prevent low blood calcium levels and to manage hyperphosphatemia (elevated phosphate levels) commonly seen in chronic kidney disease patients and those requiring dialysis.
Typically contains calcium carbonate, citrate, or acetate which either supplements deficient calcium or binds dietary phosphate in the gastrointestinal tract to reduce its absorption into the bloodstream.
Should be taken as directed with meals for optimal phosphate binding. Patients should monitor for signs of hypercalcemia. May interact with certain medications including tetracyclines, fluoroquinolones, and iron supplements. Medical supervision is required for proper dosing.
