For adult patients weighing 50 kg or more, an alternative dose of Injectafer 15 mg/kg body weight up to a maximum of 1,000 mg intravenously may be administered as a single-dose per course. ( 2.1 ) For patients weighing less than 50 kg, the recommended dosage is Injectafer 15 mg/kg body weight intravenously in two doses separated by at least 7 days per course. ( 2.1 ) See Section 2.1, Table 1 for dosage in patients with iron deficiency and heart failure. ( 2.1 ) Injectafer treatment may be repeated if IDA or iron deficiency in heart failure reoccurs. ( 2.3 ) 2.1 Recommended Dosage Recommended Dosage for Treatment of Iron Deficiency Anemia For patients weighing 50 kg or more, the recommended dosage is: Injectafer 750 mg intravenously in two doses separated by at least 7 days for a total cumulative dose of 1,500 mg of iron per course. In adult patients, Injectafer 15 mg/kg body weight up to a maximum of 1,000 mg intravenously may be administered as a single-dose per course. For patients weighing less than 50 kg, the recommended dosage is Injectafer 15 mg/kg body weight intravenously in two doses separated by at least 7 days per course. Recommended Dosage in Patients with Iron Deficiency with Heart Failure See Table 1 for recommended dosage for treatment of iron deficiency in patients with heart failure and New York Heart Association class II/III to improve exercise capacity. Table 1: Recommended Dosage in Patients with Iron Deficiency with Heart Failure Weight less than 70 kg Weight 70 kg or more Hb (g/dL) Hb (g/dL) < 10 10 to 14 > 14 to < 15 < 10 10 to 14 > 14 to < 15 Day 1 1,000 mg 1,000 mg 500 mg 1,000 mg 1,000 mg 500 mg Week 6 500 mg No dose No dose 1,000 mg 500 mg No dose Administer a maintenance dose of 500 mg at 12, 24 and 36 weeks if serum ferritin <100 ng/mL or serum ferritin 100-300 ng/mL with transferrin saturation <20%. There are no data available to guide dosing beyond 36 weeks or with Hb ≥15 g/dL. 2.2 Preparation and Administration Administer Injectafer intravenously, either as an undiluted slow intravenous push or by infusion. When administered via infusion, dilute up to 1,000 mg of iron in no more than 250 mL of sterile 0.9% sodium chloride injection, USP, such that the concentration of the infusion is not less than 2 mg of iron per mL and administer over at least 15 minutes. When added to an infusion bag containing 0.9% sodium chloride injection, USP, at concentrations ranging from 2 to 4 mg of iron per mL, Injectafer solution is physically and chemically stable for 72 hours when stored at room temperature. To maintain stability, do not dilute to concentrations less than 2 mg iron/mL. Inspect parenteral drug products visually for the absence of particulate matter and discoloration prior to administration. The product contains no preservatives. Each vial of Injectafer is intended for a single dose. When administering Injectafer 500 or 750 mg as a slow intravenous push, give at the rate of approximately 100 mg (2 mL) per minute. For Injectafer 1,000 mg, administer as a slow intravenous push over 15 minutes. Avoid extravasation of Injectafer since brown discoloration of the extravasation site may be long lasting. Monitor for extravasation. If extravasation occurs, discontinue the Injectafer administration at that site. Discard unused portion. 2.3 Repeat Treatment Monitoring Safety Assessment Injectafer treatment may be repeated if IDA or iron deficiency in heart failure reoccurs. Check serum phosphate levels in patients at risk for low serum phosphate who require a repeat course of treatment or for any patient who receives a repeat course of treatment within three months [see Warnings and Precautions ( 5.2 )]. Treat hypophosphatemia as medically indicated.

WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Observe for signs and symptoms of hypersensitivity during and after Injectafer administration for at least 30 minutes and until clinically stable following completion of each administration. ( 5.1 ) Symptomatic Hypophosphatemia: Monitor serum phosphate levels in patients at risk for low serum phosphate who require a repeat course of treatment. ( 5.2 ) Hypertension: Monitor patients closely for signs and symptoms of hypertension following each Injectafer administration. ( 5.3 ) 5.1 Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life-threatening and fatal, have been reported in patients receiving Injectafer. Patients may present with shock, clinically significant hypotension, loss of consciousness, and/or collapse. Monitor patients for signs and symptoms of hypersensitivity during and after Injectafer administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Injectafer when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions [see Adverse Reactions ( 6.1 , 6 .2 )]. In clinical trials, serious anaphylactic/anaphylactoid reactions were reported in 0.1% (2/1,775) of subjects receiving Injectafer. Other serious or severe adverse reactions potentially associated with hypersensitivity which included, but not limited to, pruritus, rash, urticaria, wheezing, or hypotension were reported in 1.5% (26/1,775) of these subjects. 5.2 Symptomatic Hypophosphatemia Symptomatic hypophosphatemia with serious outcomes including osteomalacia and fractures requiring clinical intervention has been reported in patients treated with Injectafer in the post-marketing setting. These cases have occurred mostly after repeated exposure to Injectafer in patients with no reported history of renal impairment. However, symptomatic hypophosphatemia has been reported after one dose. Possible risk factors for hypophosphatemia include a history of gastrointestinal disorders associated with malabsorption of fat-soluble vitamins or phosphate, inflammatory bowel disease, concurrent or prior use of medications that affect proximal renal tubular function, hyperparathyroidism, vitamin D deficiency, malnutrition, and hereditary hemorrhagic telangiectasia (HHT or Osler-Weber-Rendu syndrome). In most cases, hypophosphatemia resolved within three months. Correct pre-existing hypophosphatemia prior to initiating therapy with Injectafer. Monitor serum phosphate levels in patients at risk for chronic low serum phosphate. Check serum phosphate levels prior to a repeat course of treatment in patients at risk for low serum phosphate and in any patient who receives a second course of therapy within three months [see Dosage and Administration ( 2.3 )] . Treat hypophosphatemia as medically indicated. 5.3 Hypertension In clinical studies, hypertension was reported in 4% (67/1,775) of subjects in clinical trials 1 and 2. Transient elevations in systolic blood pressure, sometimes occurring with facial flushing, dizziness, or nausea were observed in 6% (106/1,775) of subjects in these two clinical trials. These elevations generally occurred immediately after dosing and resolved within 30 minutes. Monitor patients for signs and symptoms of hypertension following each Injectafer administration [see Dosage and Administration ( 2 )]. 5.4 Laboratory Test Alterations In the 24 hours following administration of Injectafer, laboratory assays may overestimate serum iron and transferrin bound iron by also measuring the iron in Injectafer.

CONTRAINDICATIONS Injectafer is contraindicated in patients with a history of hypersensitivity to Injectafer or any of its components [see Warnings and Precautions ( 5.1 ) ]. Hypersensitivity to Injectafer or any of its inactive components.

Mechanism of Action Ferric carboxymaltose is a colloidal iron (III) hydroxide in complex with carboxymaltose, a carbohydrate polymer that releases iron.
