Calcium gluconate is administered in various doses depending on the condition being treated and the route of administration.
How is calcium gluconate given?
Calcium gluconate can be administered intravenously (IV) or orally [1]. The concentration of injectable calcium gluconate solutions is typically 10% [1].
What is the typical dose for hypocalcemia?
For severe hypocalcemia, intravenous calcium gluconate is often given as an initial dose of 10-20 mL of a 10% solution. This can be repeated as needed, with slower infusions of 5-10 mL of a 10% solution administered every 10-20 minutes to maintain serum calcium levels. For less severe cases or as maintenance therapy, oral calcium gluconate is prescribed, with typical doses ranging from 1 to 4 grams of elemental calcium per day, divided into multiple doses [1].
How is calcium gluconate used in other medical situations?
In magnesium sulfate overdose, calcium gluconate is administered intravenously at a dose of 5-10 mEq (10-20 mL of 10% solution) to antagonize the cardiac effects of excess magnesium [1]. For hyperkalemic cardiac arrest, 10 mL of 10% calcium gluconate is given intravenously [1]. In cases of hydrofluoric acid burns, topical calcium gluconate gel or subcutaneous/intra-arterial injections may be used [1].
What are the risks of calcium gluconate administration?
Intravenous calcium gluconate must be administered slowly to avoid adverse effects such as hypotension, bradycardia, and cardiac arrhythmias [1]. Rapid injection can also lead to phlebitis and tissue necrosis if extravasation occurs [1]. Oral administration can cause gastrointestinal upset [1].
