Important Safety Information

Calcium Gluconate in Sodium Chloride Injection is contraindicated in hypercalcemia and in neonates (28 days of age or younger) receiving ceftriaxone.

Arrhythmias with Concomitant Cardiac Glycoside Use: If concomitant therapy is necessary, Calcium Gluconate in Sodium Chloride Injection should be given slowly in small amounts and close ECG monitoring is recommended.

End-Organ Damage due to Intravascular Ceftriaxone-Calcium Precipitates: Concurrent use of intravenous ceftriaxone may cause life-threatening precipitates. Do not administer ceftriaxone simultaneously with Calcium Gluconate in Sodium Chloride via a Y-site in any age group. Cases of fatal outcomes in neonates have occurred.

Tissue Necrosis and Calcinosis: Calcinosis cutis can occur with or without extravasation of Calcium Gluconate in Sodium Chloride Injection. Tissue necrosis, ulceration, and secondary infection are the most serious complications. If extravasation occurs or clinical manifestations of calcinosis cutis are noted, immediately discontinue intravenous administration at that site and treat as needed.

Hypotension, Bradycardia, and Cardiac Arrhythmias with Rapid Administration: To avoid adverse reactions that may follow rapid intravenous administration, Calcium Gluconate in Sodium Chloride Injection should be infused slowly, with careful ECG monitoring for cardiac arrhythmias.
Aluminum Toxicity: This product contains aluminum, up to 100 mcg per liter, that may be toxic.

The most common adverse events with Calcium Gluconate Injection are local soft tissue inflammation and necrosis, calcinosis cutis and calcification that are related to extravasation. Other adverse events include vasodilation, decreased blood pressure, bradycardia, cardiac arrhythmia, syncope, and cardiac arrest.
