DOSAGE AND ADMINISTRATION 2.1 Important Administration Instructions Calcium Gluconate Injection contains 100 mg of calcium gluconate per mL which contains 9.3 mg (i.e., 0.465 mEq) of elemental calcium. Dilute Calcium Gluconate Injection prior to use in 5% dextrose or normal saline and assess for potential drug or IV fluid incompatibilities [see Dosage and Administration ( 2.5 )] . 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 [see Warnings and Precautions ( 5.3)] . Administer Calcium Gluconate Injection by bolus administration nor continuous infusion: For bolus intravenous administration: Dilute the dose [see Dosage and Administration ( 2.2 )] of Calcium Gluconate Injection in 5% dextrose or normal saline to a concentration 10-50 mg/mL prior to administration. Administer the dose slowly and DO NOT exceed an infustion rate of 200 mg/minute in adults or 100 mg/minute in pediatric patients, including neonates. Monitor patients, vitals and electrocardiograph (ECG) during administration [see Warnings and Precautions ( 5.4 )] . For continuous intravenous infusion: Dilute Calcium Gluconate Injection in 5% dextrose or normal saline to a concentration of 5.8-10 mg/mL prior to administration. Administer at the rate recommended in Table 1 [see Dosage and Administration ( 2.2 )] and monitor patients, vitals, calcium and ECG during the infusion [see Warnings and Precautions ( 5.4 )] . Calcium Gluconate Injection is supplied in single-dose vials and pharmacy bulk packages [see Dosage and Administration ( 2.6 )]. 2.2 Recommended Dosage Individualize the dose of Calcium Gluconate Injection within the recommended range depending on the severity of symptoms of hypocalcemia, the serum clacium level, and the acuity of onset of hypocalcemia. Table 1 provides dosing recommendations for Calcium Gluconate Injection in mg of calcium gluconate for neonates, pediatric and adult patients. Table 1. Dosing Recommendations in mg of Calcium Gluconate for Neonate, Pediatric, and Adult Patients 2.3 Serum Calcium Monitoring Measure serum calcium every 4 to 6 hours during intermittent infusions with Calcium Gluconate Injection and measure serum calcium every 1 to 4 hours during continuous infusion. 2.4 Dosage in Renal Impairment For patients with renal impairment, initiate Calcium Gluconate Injection at the lowest dose of the recommended dose ranges for all age groups and monitor serum calcium levels every 4 hours. 2.5 Drug Incompatibilities Do not mix Calcium Gluconate Injection with ceftriaxone. Concurrent use of intravenous ceftriaxone and Calcium Gluconate Injection can lead to the formation of ceftriaxone-calcium precipitates. Concomitant use of ceftriaxone and intravenous calcium-containing products is contraindicated in neonates (28 days of age or younger) see Contraindications (4) ]. In patients older than 28 days of age, ceftriaxone and calcium-containing products may be administered sequentially, provided the infusion lines are thoroughly flushed between infusions with a compatible fluid. Ceftriaxone must not be administered simultaneously with intravenous calcium-containing solutions via a Y-site in any age group [see Warnings and Precautions ( 5.2 ), Drug Interactions ( 7.3 )]. Do not mix Calcium Gluconate Injection with fluids containing bicarbonate or phosphate. Calcium Gluconate Injection is not physically compatible with fluids containing phosphate or bicarbonate. Precipitation may result if mixed. Do not mix Calcium Gluconate Injection with minocycline injection. Calcium complexes minocycline rendering it inactive. 2.6 Preparation of Pharmacy Bulk Package The pharmacy bulk package (PBP) of Calcium Gluconate Injection is intended for dispensing of single doses to multiple patients in a pharmacy admixture program. Penetrate the container closure only one time with a suitable sterile transfer device or dispensing set that allows measured dispensing of the contents.

(1) Limitations of Use: The safety of Calcium Gluconate Injection for long term use has not been established. (2)

OVERDOSAGE Overdosage of Calcium Gluconate 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 Injection occurs immediately discontinue administration and provide supportive treatments to restore intravascular volume as well as promote calcium excretion in the urine if necessary.

DRUG INTERACTIONS 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 Injection in patients receiving cardiac glycosides; if considered necessary, administer Calcium Gluconate 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. Cardiac Glycoside : Synergistic arrhythmias may occur if calcium and cardiac glycosides are administered together.

CLINICAL PHARMACOLOGY 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 normal constituents of body fluids. 12.3 Pharmacokinetics Absorption Calcium Gluconate Injection is 100% bioavailable following intravenous injection. Metabolism Calcium iteself does not undergo direct metabolism. The release of ionized calcium from intravenous administration of calcium gluconate is direct and does not seem to be affected by the first pass through the liver. Distribution Calcium in the body is distributed mainly in skeleton (99%). Only 1% of the total body calcium is distributed within the extracellular fluids and soft tissues. About 50% of total serum calcium is in the ionized form and represents the biologically active part. 8% to 10% serum calcium is bound to organic and inorganic acid and approximately 40% is protein-bound (primarily to ablumin). Elimination Studies have shown a relationship between urinary calcium excretion and the intravenous administration of calcium gluconate, with a significant increase in urinary calcium excretion observed after the intravenous administration of calcium gluconate.

USE IN SPECIFIC POPULATIONS 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 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 Injection and any potential adverse effects on the breastfed child from Calcium Gluconate Injection or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of Calcium Gluconate Injection have been established in pediatric patients for the treatment of acute, symptomatic hypocalcemia. Pediatric approval for Calcium Gluconate 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 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 precitpiates. 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 400 mcg/mL aluminum which may be toxic, particularly for premature neonates due to immature renal function. parenteral administration of aluminum greater than 4 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 oether drug therapy. 8.6 Renal Impairment For patients with renal impairment, initiate Calcium Gluconate Injection at the loest dose of the recommended dose ranges across all age groups. Monitor serum calcium levels every 4 hours [see Dosage and Administration ( 2.4 )]. 8.7 Hepatic Impairment Hepatic function does not impact the availability of ionized calcium after clacium gluconate intravenous administration. Dose adjustment in hepatically imapired patients may not be necessary. Geriatric use: Dosing in elderly patietns should be cautions, 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 ) See 17 for PATIENT COUNSELING INFORMATION Revised: 7/2018
