Always consult a medical doctor or patient care specialist before using calcium gluconate injections.
Indications and Usage
Calcium gluconate injections are used to treat conditions arising from low calcium, such as hypocalcemia due to hypoparathyroidism, rapid growth, or pregnancy. This drug can also be used to treat black widow spider bites, lead colic, magnesium sulfate overdose, rickets, and life-threatening cardiac toxicity.
Calcium gluconate is also known to lessen capillary permeability in allergic conditions, nonthrombocytopenic purpura and exudative dermatoses such as dermatitis herpetiformis and for pruritus of eruptions. This drug can also be used to treat cardiac toxicity in hyperkalemia, provided that the patient is not receiving digitalis therapy.
Each mL of calcium gluconate injection contains 100mg of calcium chloride.
It is contraindicated in patients with ventricular fibrillation or hypercalcemia. Intravenous administration of calcium is contraindicated when serum calcium levels are above normal. It is also contraindicated in neonates who are 28 years of age or younger.
Do not take calcium gluconate injections if:
- You are allergic to calcium gluconate or other containing ingredients;
- You have hypercalcemia or ventricular fibrillation;
- You develop hypotension, bradycardia, and cardiac arrhythmias with rapid administration;
- You develop tissue necrosis and calcinosis.
There is little evidence with regards to the use of calcium gluconate during pregnancy or breast feeding, and so consult your doctor or health care professional before injecting calcium gluconate.
