How is acute hypocalcaemia treated in adults?
... Asymptomatic, mild hypocalcaemia is usually treated with oral calcium supplements (1,2) at a dose of 10 to 50 mmol daily for simple deficiency states and adjusted to the patient’s individual requirements (10). Calcium carbonate is the most frequently supplied calcium salt (11) and is well tolerated ...
