6 ADVERSE REACTIONS The following serious adverse reactions are also described elsewhere in the labeling: • Arrhythmias with Concomitant Cardiac Glycoside Use [see Warnings and Precautions (5.1)] • End-Organ Damage due to Intravascular Ceftriaxone-Calcium Precipitates [see Warnings and Precautions (5.2)] • Tissue Necrosis and Calcinosis [see Warnings and Precautions (5.3)] • Hypotension, Bradycardia, and Cardiac Arrhythmias [see Warnings and Precautions (5.4)] • Aluminum toxicity [see Warnings and Precautions (5.5)] The following adverse reactions associated with the use of calcium gluconate were identified in the literature. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure. Cardiovascular : Vasodilation, decreased blood pressure, bradycardia, cardiac arrhythmia, syncope, cardiac arrest Administration site reactions : Local soft tissue inflammation, local necrosis, calcinosis cutis and calcification due to extravasation 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.

7 DRUG INTERACTIONS • Cardiac Glycoside : Synergistic arrhythmias may occur if calcium and cardiac glycosides are administered together. (7.1) • Calcium Channel Blockers : Administration of calcium may reduce the response. (7.2) • Drugs that may cause hypercalcemia: Vitamin D, vitamin A, thiazide diuretics, estrogen, calcipotriene and teriparatide administration may cause hypercalcemia. Monitor plasma calcium concentrations in patients taking these drugs concurrently. (7.3) 7.1 Cardiac Glycosides Hypercalcemia increases the risk of digoxin toxicity, while digoxin may be therapeutically ineffective in the presence of hypocalcemia. Synergistic arrhythmias may occur if calcium and cardiac glycosides are administered together. Avoid administration of Calcium Gluconate in Sodium Chloride Injection in patients receiving cardiac glycosides; if considered necessary, administer Calcium Gluconate in Sodium Chloride Injection slowly in small amounts and monitor ECG closely during administration. 7.2 Calcium Channel Blockers Administration of calcium may reduce the response to calcium channel blockers. 7.3 Drugs that may cause Hypercalcemia Vitamin D, vitamin A, thiazide diuretics, estrogen, calcipotriene and teriparatide administration may cause hypercalcemia. Monitor plasma calcium concentrations in patients taking these drugs concurrently.

8 USE IN SPECIFIC POPULATIONS • Geriatric use : Dosing in elderly patients should be cautious, usually starting at the low end of the dosage range. (8.5) • Renal impairment: Initiate with the lower limit of the dosage range and monitor serum calcium levels every 4 hours. (8.6, 2.4) 8.1 Pregnancy Risk summary Limited available data with Calcium Gluconate Injection use in pregnant women are insufficient to inform a drug associated risk of adverse developmental outcomes. There are risks to the mother and the fetus associated with hypocalcemia in pregnancy [see Clinical Considerations] . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Disease-associated maternal risk Maternal hypocalcemia can result in an increased rate of spontaneous abortion, premature and dysfunctional labor, and possibly preeclampsia. Fetal/Neonatal adverse reactions Infants born to mothers with hypocalcemia can have associated fetal and neonatal hyperparathyroidism, which in turn can cause fetal and neonatal skeletal demineralization, subperiosteal bone resorption, osteitis fibrosa cystica and neonatal seizures. Infants born to mothers with hypocalcemia should be carefully monitored for signs of hypocalcemia or hypercalcemia, including neuromuscular irritability, apnea, cyanosis and cardiac rhythm disorders. 8.2 Lactation Risk summary Calcium is present in human milk as a natural component of human milk. It is not known whether intravenous administration of Calcium Gluconate in Sodium Chloride Injection can alter calcium concentration in human milk. There are no data on the effects of Calcium Gluconate Injection on the breastfed infant, or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Calcium Gluconate in Sodium Chloride Injection and any potential adverse effects on the breastfed child from Calcium Gluconate in Sodium Chloride Injection or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of Calcium Gluconate in Sodium Chloride Injection have been established in pediatric patients for the treatment of acute, symptomatic hypocalcemia. Pediatric approval for Calcium Gluconate in Sodium Chloride Injection, including doses, is not based on adequate and well-controlled clinical studies. Safety and dosing recommendations in pediatric patients are based on published literature and clinical experience [see Dosage and Administration (2.2)] . Concomitant use of ceftriaxone and Calcium Gluconate in Sodium Chloride Injection is contraindicated in neonates (28 days of age or younger) due to reports of fatal outcomes associated with the presence of lung and kidney ceftriaxone-calcium precipitates. In patients older than 28 days of age, ceftriaxone and Calcium Gluconate Injection may be administered sequentially, provided the infusion lines are thoroughly flushed between infusions with a compatible fluid [ see Contraindications (4) and Warnings and Precautions (5.2)] . This product contains up to 25 mcg/L aluminum which may be toxic, particularly for premature neonates due to immature renal function. Parenteral administration of aluminum greater than 4 mcg/kg/day to 5 mcg/kg/day is associated with central nervous system and bone toxicity [see Warnings and Precautions (5.5)] . 8.5 Geriatric Use In general dose selection for an elderly patient should start at the lowest dose of the recommended dose range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. 8.6 Renal Impairment For patients with renal impairment, initiate Calcium Gluconate in Sodium Chloride Injection at the lowest dose of the recommended dose ranges …

12.1 Mechanism of Action Intravenous administration of calcium gluconate increases serum ionized calcium level. Calcium gluconate dissociates into ionized calcium in plasma. Ionized calcium and gluconate are constituents of body fluids.

10 OVERDOSAGE Overdosage of Calcium Gluconate in Sodium Chloride Injection may result in hypercalcemia. Symptoms of hypercalcemia typically develop when the total serum calcium concentration is ≥12 mg/dL. Neurologic symptoms include depression, weakness, fatigue, and confusion at lower levels, with patients experiencing hallucinations, disorientation, hypotonicity, seizures, and coma. Effects on the kidney include diminished ability to concentrate urine and diuresis. If overdose of Calcium Gluconate in Sodium Chloride Injection occurs immediately discontinue administration and provide supportive treatments to restore intravascular volume as well as promote calcium excretion in the urine if necessary.
