2 DOSAGE AND ADMINISTRATION Adult Patients - The recommended adult dosage is 10 mL (125 mg of elemental iron) diluted in 100 mL of 0.9% sodium chloride administered by intravenous infusion over 1 hour per dialysis session or undiluted as a slow intravenous injection (at a rate of up to 12.5 mg/min) per dialysis session. ( 2.2 ) Pediatric Patients - The recommended pediatric dosage is 0.12 mL/kg (1.5 mg/kg of elemental iron) diluted in 25 mL 0.9% sodium chloride and administered by intravenous infusion over 1 hour per dialysis session. ( 2.3 ) Do not mix sodium ferric gluconate complex in sucrose injection with other medications or add to parenteral nutrition solutions for intravenous infusion. Administer in 0.9% saline. ( 2 ) 2.1 Important Administration Instructions The dosage of sodium ferric gluconate complex in sucrose injection is expressed in terms of mg of elemental iron. Each 5 mL sterile, single dose vial contains 62.5 mg of elemental iron (12.5 mg/mL). Do not mix sodium ferric gluconate complex in sucrose injection with other medications or add to parenteral nutrition solutions for intravenous infusion. The compatibility of sodium ferric gluconate complex in sucrose injection with intravenous infusion vehicles other than 0.9% sodium chloride has not been evaluated. Parenteral drug products should be inspected visually for particulate matter and discoloration before administration, whenever the solution and container permit. If diluted, use immediately. Sodium ferric gluconate complex in sucrose injection treatment may be repeated if iron deficiency reoccurs. 2.2 Adult Dosage and Administration The recommended dosage of sodium ferric gluconate complex in sucrose injection for the repletion treatment of iron deficiency in hemodialysis patients is 10 mL of sodium ferric gluconate complex in sucrose injection (125 mg of elemental iron). Sodium ferric gluconate complex in sucrose injection may be diluted in 100 mL of 0.9% sodium chloride administered by intravenous infusion over 1 hour per dialysis session. Sodium ferric gluconate complex in sucrose injection may also be administered undiluted as a slow intravenous injection (at a rate of up to 12.5 mg/min) per dialysis session. For repletion treatment most patients may require a cumulative dose of 1000 mg of elemental iron administered over 8 dialysis sessions. Sodium ferric gluconate complex in sucrose injection has been administered at sequential dialysis sessions by infusion or by slow intravenous injection during the dialysis session itself. Data from sodium ferric gluconate complex in sucrose injection postmarketing spontaneous reports indicate that individual doses exceeding 125 mg may be associated with a higher incidence and/or severity of adverse events [see Adverse Reactions ( 6.2 ) ]. 2.3 Pediatric Dosage and Administration The recommended pediatric dosage of sodium ferric gluconate complex in sucrose injection for the repletion treatment of iron deficiency in hemodialysis patients is 0.12 mL/kg sodium ferric gluconate complex in sucrose injection (1.5 mg/kg of elemental iron) diluted in 25 mL 0.9% sodium chloride and administered by intravenous infusion over 1 hour per dialysis session. The maximum dosage should not exceed 125 mg per dose.

8 USE IN SPECIFIC POPULATIONS Pregnancy: Risk of hypersensitivity reaction which may have serious consequences for the fetus. Use only if clearly needed (contains benzyl alcohol). ( 8.1 ) Lactation: Not recommended when breastfeeding. ( 8.2 ) Pediatric Use: Safety and effectiveness have not been established in pediatric patients <6 years of age. ( 8.4 ) 8.1 Pregnancy Risk Summary Parenteral iron administration may be associated with hypersensitivity reactions [see Warnings and Precautions ( 5.1 ) ], which may have serious consequences, such as fetal bradycardia (see Clinical Considerations ). Advise pregnant women of the potential risk to the fetus. Available data from postmarketing reports with sodium ferric gluconate complex in sucrose injection use in pregnancy are insufficient to assess the risk of major birth defects and miscarriage. Sodium ferric gluconate complex in sucrose injection contains benzyl alcohol as a preservative. Because benzyl alcohol is rapidly metabolized by a pregnant woman, benzyl alcohol exposure in the fetus is unlikely. However, adverse reactions have occurred in premature neonates and low-birth-weight infants who received intravenously administered benzyl alcohol-containing drugs [see Warnings and Precautions ( 5.4 ) and Use in Specific Populations ( 8.4 ) ]. Consider alternative iron replacement therapies without benzyl alcohol. There are risks to the mother and fetus associated with untreated iron deficiency anemia in pregnancy (see Clinical Considerations ). In the absence of maternal toxicity, sodium ferric gluconate complex in sucrose injection was not teratogenic to offspring of pregnant mice or rats at clinically relevant exposures (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. 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 and/or Embryo/Fetal Risk Untreated iron deficiency anemia (IDA) in pregnancy is associated with adverse maternal outcomes such as postpartum anemia. Adverse pregnancy outcomes associated with IDA include increased risk for preterm delivery and low-birth-weight. Fetal/Neonatal Adverse Reactions Severe adverse reactions including circulatory failure (severe hypotension, shock including in the context of anaphylactic reaction) may occur in pregnant women with intravenous iron administration, which may have serious consequences on the fetus such as fetal bradycardia, especially during the second and third trimesters. Data Animal Data Sodium ferric gluconate complex in sucrose injection was administered intravenously to pregnant mice during gestation days 6 to 15 at doses of 5, 30, and 100 mg Fe/kg/day to assess embryofetal development. No teratogenic effects were seen in offspring at the highest dose, representing maternal exposure of approximately 4 times maximum human exposure based on body surface area. There were increased fetal resorptions and decreased fetal weights at doses that caused maternal toxicity as evidenced by decreased body-weight gain and decreased food consumption. Sodium ferric gluconate complex in sucrose injection was administered intravenously to pregnant rats during gestation days 6 to 15 at doses of 4 and 20 mg Fe/kg/day to assess embryofetal development. No teratogenic effects were seen in offspring at the highest dose, representing maternal exposure of approximately 1.5 times maximum human exposure based on body surface area. There were decreases in gestation index and litter size, increased fetal resorptions, and decreased fetal weights at doses that caused maternal toxicity as evidenced by decreased body-weight gain and decreased food consumption. 8.2.

The macromolecular complex is negatively charged at alkaline pH and is present in solution with sodium cations. The product has a deep red color indicative of ferric oxide linkages. The chemical name is D-Gluconic acid, iron (3+) sodium salt. The structural formula is considered to be [NaFe 2 O 3 (C 6 H 11 O 7 )(C 12 H 22 O 11 )5] n≈200 . Each sterile, single dose vial of 5 mL of sodium ferric gluconate complex in sucrose injection for intravenous injection contains 62.5 mg (12.5 mg/mL) of elemental iron as the sodium salt of a ferric ion carbohydrate complex in an alkaline aqueous solution with approximately 20% sucrose w/v (195 mg/mL) in water for injection, pH 7.7 - 9.7. Each mL contains 9 mg of benzyl alcohol as an inactive ingredient.

10 OVERDOSAGE The sodium ferric gluconate complex in sucrose injection iron complex is not dialyzable. No data is available regarding overdose of sodium ferric gluconate complex in sucrose injection in humans. Excessive dosages of sodium ferric gluconate complex in sucrose injection may lead to accumulation of iron in storage sites potentially leading to hemosiderosis. Do not administer sodium ferric gluconate complex in sucrose injection to patients with iron overload [see Warnings and Precautions ( 5.3 ) ]. Individual doses exceeding 125 mg may be associated with a higher incidence and/or severity of adverse events [see Adverse Reactions ( 6.2 ) ] . Sodium ferric gluconate complex in sucrose injection at elemental iron doses of 125 mg/kg, 78.8 mg/kg, 62.5 mg/kg and 250 mg/kg caused deaths in mice, rats, rabbits, and dogs respectively. The major symptoms of acute toxicity were decreased activity, staggering, ataxia, increases in the respiratory rate, tremor, and convulsions.
