For asymptomatic hypocalcemia, what is the recommended treatment?

• A. IV calcium
• B. IV calcium gluconate
• C. Calcitonin
• D. Oral calcium

Answer: (D)

When hypocalcemia is asymptomatic, the best approach is to raise calcium safely over time with oral calcium supplementation, usually with calcium carbonate or calcium citrate, often alongside vitamin D to improve absorption. This route corrects deficiency without the risks of rapid correction that come with IV calcium. Intravenous calcium is reserved for those who have symptoms such as numbness or tingling around the mouth, muscle cramps, tetany, seizures, or cardiac manifestations indicating the need for urgent correction. Calcitonin isn’t used to treat low calcium, as it lowers calcium levels rather than raises them. Also, address any underlying causes (like vitamin D deficiency or low magnesium) and monitor calcium levels after starting therapy, adjusting as needed.
