Indications and clinical uses. Calcium carbonate is used as an oral calcium supplement for hypocalcemia, sometimes used with vitamin D supplements or calcitriol. It contains 40% elemental calcium. It is used as antacid to treat gastric hyperacidity and gastrointestinal (GI) ulcers and as an intestinal phosphate binder for hyperphosphatemia associated with renal failure.
