Calcium Gluconate

Generic name: Calcium Gluconate (oral/injection)

Usage of Calcium Gluconate

How to use Calcium Gluconate

Usual Adult Dose for Hypocalcemia:

Intravenous: 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. Oral: 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:

1000 to 1500 mg/day orally in divided doses.

Hypocalcemia secondary to citrated blood infusion: IV: Give 0.45 mEq elemental calcium for each 100 mL citrated blood infused Tetany: IV: (Dose expressed in mg of calcium gluconate): Infants and Children: 100 to 200 mg/kg/dose; over 5 to 10 minutes; may repeat after 6 hours or follow with an infusion with a maximum dose of 500 mg/kg/day. Daily maintenance calcium: IV: Infants and Children 25 kg and less: 1 to 2 mEq/kg/day Children 25 to 45 kg: 0.5 to 1.5 mEq/kg/day Children greater than 45 kg: 0.2 to 0.3 mEq/kg/day or 10 to 20 mEq/day

Warnings

Do not take calcium gluconate or antacids that contain calcium without first asking your doctor if you also take other medicines. Calcium can make it harder for your body to absorb certain medicines. Calcium gluconate works best if you take it with food.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

What other drugs will affect Calcium Gluconate

Calcium can make it harder for your body to absorb certain medicines. If you take other medications, take them at least 2 hours before or 4 or 6 hours after you take calcium gluconate.

Tell your doctor about all your current medicines. Many drugs can interact with calcium gluconate, especially:

Baloxavir marboxil (Xofluza);

digoxin (digitalis);

an antibiotic; or

other forms of calcium.

This list is not complete and many other drugs may interact with calcium gluconate. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
