Dosing Recommendations in mg of Calcium Gluconate for Neonate, Pediatric, and Adult Patients

Patient Population	Initial Dose	Bolus dose	Continuous Infusion
Neonate(≤ 1 month)	100 – 200 mg/kg	100 - 200 mg/kg every 6 hours	Initiate at 17-33 mg/kg/hour
Pediatric(> 1 month to < 17 years)	29 - 60 mg/kg	29 - 60 mg/kg every 6 hours	Initiate at 8-13 mg/kg/hour
Adult	1000 - 2000 mg	1000 - 2000 mg every 6 hours	Initiate at 5.4 - 21.5 mg/kg/hour

Administration:

• Dilute Calcium Gluconate Injection prior to use in 5% dextrose or normal saline and assess for potential drug or IV fluid incompatibilities.
• Inspect Calcium Gluconate Injection visually prior to administration.
• The solution should appear clear and colorless to slightly yellow.
• Do not administer if there is particulate matter or discoloration.
• Use the diluted solution immediately after preparation.
• Administer Calcium Gluconate Injection intravenously via a secure intravenous line to avoid calcinosis cutis and tissue necrosis.
• Administer Calcium Gluconate Injection by bolus administration or continuous infusion.

What side effects can this medication cause?

The most common side effects of this medicine include:

• 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.

Calcium Gluconate may cause serious side effects which may include:

• Arrhythmias
• End-Organ Damage
• Tissue Necrosis and Calcinosis
• Hypotension
• Bradycardia
• Cardiac Arrhythmias
• Aluminum toxicity

What special precautions should I follow?

• Cardiac arrhythmias may occur if calcium and cardiac glycosides are administered together. If concomitant therapy is necessary, Calcium Gluconate Injection should be given slowly in small amounts and with close ECG monitoring.
• Concomitant use of ceftriaxone and Calcium Gluconate Injection is contraindicated in neonates (28 days of age or younger). Cases of fatal outcomes in neonates have occurred.
• Intravenous administration of Calcium Gluconate Injection and local trauma may result in calcinosis cutis due to transient increase in local calcium concentration. 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.
• Rapid injection of Calcium Gluconate Injection may cause vasodilation, decreased blood pressure, bradycardia, cardiac arrhythmias, syncope and cardiac arrest. To avoid adverse reactions that may follow rapid intravenous administration, Calcium Gluconate Injection should be diluted with 5% dextrose or normal saline and infused slowly, with careful ECG monitoring for cardiac arrhythmias.
• Calcium Gluconate Injection contains aluminum, up to 512 mcg per liter, that may be toxic.
• Calcium is present in human milk as a natural component of human milk. It is not known whether intravenous administration of Calcium Gluconate Injection can alter calcium concentration in human milk.

What to do in case of emergency/overdose?

• hallucinations
• disorientation
• hypotonicity
• seizures
• coma
