Hypercalcemia is commonly encountered in the clinical setting and requires identification by the clinician to avoid disastrous patient outcomes. The 2 most common causes are malignancy and hyperparathyroidism. The underlying cause for hypercalcemia may be readily known at presentation or may require further investigation. After identification, acuity of treatment will depend on severity of calcium level and symptoms. In the emergency setting, intravenous hydration with isotonic fluids is the treatment mainstay. Other commonly used medications to further decrease calcium include bisphosphates, calcitonin, steroids, and (rarely) furosemide. In life-threatening circumstances, dialysis can be implemented.
