What is the treatment for hypocalcemia?

• A. Replacement is necessary as it can cause Torsades de Pointes
• B. Calcium gluconate IV is commonly used as initial therapy
• C. Vitamin D supplementation alone is sufficient
• D. Loop diuretics are the preferred treatment

Answer: (C)

Treat hypocalcemia by quickly restoring calcium and then sustaining it while addressing the underlying cause. In an acute, symptomatic patient, immediate calcium replacement is essential to prevent life-threatening complications from neuromuscular irritability and potential arrhythmias. The typical initial therapy is intravenous calcium, with calcium gluconate being the common choice. This should be given with careful ECG monitoring and attention to infusion related risks. After the patient is stabilized, maintenance therapy is usually oral calcium supplementation to keep levels up, combined with vitamin D to improve calcium absorption from the gut. Vitamin D alone does not correct the problem quickly enough because without sufficient calcium to absorb, serum calcium cannot rise to safe levels. In many cases, especially with vitamin D deficiency or malabsorption, calcitriol or other active vitamin D forms may be used alongside calcium. Also consider and correct related factors that can impair calcium status, such as hypomagnesemia, which can make hypocalcemia harder to treat if not corrected. Loop diuretics should not be used to treat hypocalcemia; they promote calcium loss in the kidneys and can worsen the deficit. In short, acute management centers on IV calcium replacement to rapidly increase serum calcium, followed by ongoing oral calcium with vitamin D (and addressing any contributing causes) to maintain normocalcemia.
