What is the treatment of tetany?

The treatment of tetany depends on its underlying cause. Intravenous calcium is usually the treatment of choice. For hypomagnesemia-induced tetany, slow administration of magnesium sulfate is required. Potassium and chloride deficiencies should also be corrected if these ions are low. Underlying conditions such as hypoparathyroidism, renal disease, or other endocrine disorders may also need to be treated.
