Calcium gluconate Dosing Information
Usual Adult Dose for Hypocalcemia:
500 to 2000 mg (5 to 20 mL) IV one time at a rate not to exceed 0.5 to 2 mL/min. The dose may be increased as needed. The usual daily dosage ranges from 1000 to 15,000 mg (10 to 150 mL) in divided doses or as a continuous infusion. Doses may be repeated every 1 to 3 days as needed and tolerated to normalize the serum calcium level.
500 to 2000 mg orally 2 to 4 times a day.
Usual Adult Dose for Hypermagnesemia:
1000 to 2000 mg (10 to 20 mL) IV one time at a rate not to exceed 0.5 to 2 mL/min. This dose may be repeated as necessary in severe cases of hypermagnesemia (where discontinuation of exogenous magnesium is inadequate) to temporarily reverse many of the toxic effects of magnesium in the central nervous system.
Usual Adult Dose for Hyperkalemia:
500 to 3000 mg (5 to 30 mL) IV one time at a rate not to exceed 0.5 to 2 mL/min. This dose may be repeated as necessary in cases of extreme hyperkalemia cardiotoxicity when P waves are absent, the QRS complexes are widened, and when continuous ECG monitoring is available. The use of calcium does not reduce the serum potassium level, but counteracts the effects of hyperkalemia on cardiac excitability.
Usual Adult Dose for Exchange Transfusion:
300 mg (3 mL) IV one time with each 100 mL of citrated blood at a rate not to exceed 0.5 to 2 mL/min.
Usual Adult Dose for Osteoporosis:
