Hypercalcemia can be due to a variety of causes such as hypervitaminosis D, overuse of intravenous calcium preparations, and even milk-alkali syndrome. The treatment of hypercalcemia consists of hydration (with IV Fluids), alkalinization of urine by giving a diuretic. If the hypercalcemia still persists, then intravenous
Pamidronate (bisphosphonate) in a dose of 0.5 mg/kg would be required to bring the serum calcium down. If hypervitaminosis D is the cause of hypercalcemia, then oral steroids (prednisolone – 1 mg/kg/day x 5 days) would aid in decreasing the absorption of calcium from the intestines.
