2 DOSAGE AND ADMINISTRATION See Full Prescribing Information for weight-based dosing and administration information. ( 2 ) Weight in Kg Weight in Kg INFeD dose volume 2.1 Important Pre-Treatment Information Discontinue administration of any iron-containing products prior to administration of INFeD. Assess baseline hematologic (hemoglobin and hematocrit) and iron storage parameters (serum iron, total iron binding capacity, and percent saturation of transferrin) to monitor response to therapy. Administer a test dose of INFeD prior to administration of therapeutic dose [see Dosage and Administration ( 2.4 )] . 2. 2 Recommended Dosage for Iron Deficiency Anemia Calculate the INFeD dose based upon Table 1 and formulas below. Continue INFeD until hemoglobin is within the normal range and iron stores are replete. Administer daily doses of no more than 2 mL of INFeD until the total required dose is administered. Monitor response to therapy by evaluating hematologic parameters (hemoglobin and hematocrit) and iron storage parameters (serum iron, total iron binding capacity, and percent saturation of transferrin). Iron storage parameters may improve prior to hematologic parameters. Serum ferritin may not be an accurate measure of body iron stores in patients on chronic dialysis.

7 DRUG INTERACTIONS 7.1 Drug/Laboratory Test Interactions Drug interactions involving INFeD have not been studied. Concomitant use of angiotensin-converting enzyme inhibitor drugs may increase the risk for anaphylactic-type reactions to an iron dextran product. Large doses of iron dextran (5 mL or more) have been reported to give a brown color to serum from a blood sample drawn 4 hours after administration. INFeD may cause falsely elevated values of serum bilirubin and falsely decreased values of serum calcium. Serum iron determinations (especially by colorimetric assays) may not be meaningful for 3 weeks following the administration of INFeD. Examination of the bone marrow for iron stores may not be meaningful for prolonged periods following iron dextran therapy because residual iron dextran may remain in the reticuloendothelial cells. Bone scans involving 99m Tc-diphosphonate have been reported to show a dense, crescentic area of activity in the buttocks, following the contour of the iliac crest, 1 to 6 days after intramuscular injections of INFeD. Bone scans with 99m Tc-labeled bone seeking agents, in the presence of high serum ferritin levels or following INFeD infusions, have been reported to show reduction of bony uptake, marked renal activity, and excessive blood pool and soft tissue accumulation.

8 USE IN SPECIFIC POPULATIONS 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 persons of the potential risk to the fetus. Available data from postmarketing reports with iron dextran use in pregnancy are insufficient to assess the risk of major birth defects or miscarriage. There are risks to the pregnant person and fetus associated with untreated iron deficiency anemia in pregnancy (see Clinical Considerations). Iron dextran has been shown to be teratogenic and embryocidal in mice, rats, rabbits, dogs, and monkeys when given in doses of about 3 times the maximum human dose. 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 post-partum 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 persons with intravenous iron administration (such as INFeD) which may have serious consequences on the fetus such as fetal bradycardia, especially during the second and third trimester. Data Animal Data No consistent adverse fetal effects were observed in mice, rats, rabbits, dogs, and monkeys at doses of 50 mg iron/kg or less. Fetal and maternal toxicity has been reported in monkeys at a total intravenous dose of 90 mg iron/kg over a 14 day period. Similar effects were observed in mice and rats on administration of a single dose of 125 mg iron/kg. Fetal abnormalities in rats and dogs were observed at doses of 250 mg iron/kg and higher. The animals used in these tests were not iron deficient. 8.2 Lactation Risk Summary Trace amounts of unmetabolized iron dextran are present in human milk. There are no data on the effects of iron dextran in breastfed infants or effects on milk production. The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for INFeD in addition to any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition. 8.4 Pediatric Use INFeD is not recommended for use in infants under 4 months of age [see Dosage and Administration (2.2)]. Reports in the literature from countries outside the United States (in particular, New Zealand) have suggested that the use of intramuscular iron dextran in neonates has been associated with an increased incidence of gram-negative sepsis, primarily due to E. Coli. Pregnancy: Risk of hypersensitivity reaction which may have serious consequences for the fetus. (8.1) See 17 for PATIENT COUNSELING INFORMATION. Revised: 08/2024

12.1 Mechanism of Action The circulating iron released from iron dextran, which is subject to physiological control, replenishes hemoglobin and depleted iron stores.

11 DESCRIPTION INFeD (iron dextran injection USP) is an iron replacement product provided as a dark brown, slightly viscous sterile liquid complex of ferric hydroxide and dextran for intravenous or intramuscular use. Each mL contains the equivalent of 50 mg of elemental iron (as an iron dextran complex), approximately 0.9% sodium chloride, in water for injection. Sodium hydroxide and/or hydrochloric acid may have been used to adjust pH. The pH of the solution is between 4.5 to 7.0.

10 OVERDOSAGE Excessive dosages of INFeD may lead to accumulation of iron in storage sites potentially leading to hemosiderosis. Do not administer INFeD to patients with iron overload [see Warnings and Precautions ( 5.4 )] . INFeD is not removed by hemodialysis [see Clinical Pharmacology ( 12.3 )] .
