Frequently Asked Questions
Which patients can receive Injectafer IV iron?
Injectafer is indicated for the treatment of iron deficiency anemia (IDA) in adult patients who have intolerance to oral iron or have had unsatisfactory response to oral iron, and in adult patients with non-dialysis-dependent chronic kidney disease.1
What size infusion bag is needed?
Dilute Injectafer in up to 250 mL (but not more) 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.1 If you need further guidance, contact your Injectafer Territory Manager to arrange a consultation with a Clinical Nurse Manager.
What size needle do I use?
The infusion nurse or administering healthcare professional should assess the patient’s vein status and choose an appropriate gauge needle. If you need further guidance, contact your Injectafer Territory Manager to arrange a consultation with a Clinical Nurse Manager.
Do I need filtered tubing?
Filtered tubing is not necessary. If you need further guidance, contact your Injectafer Territory Manager to arrange a consultation with a Clinical Nurse Manager.
How do I mix Injectafer?
Dilute up to 750 mg of Injectafer in up to 250 mL (but not more) 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. Administer over at least 15 minutes.1
At concentrations ranging from 2 mg 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.1
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 single-use only. Any unused drug remaining after injection must be discarded.1
What is the dosing for patients who weigh 50 kg or more?
For patients weighing 50 kg (110 lb) or more: Give Injectafer in two doses separated by at least 7 days. Give each dose as 750 mg for a total cumulative dose of 1500 mg of iron per course.1 Learn more about Injectafer, the only IV iron that delivers up to 1500 mg in 2 administrations, separated by at least 7 days.
What is the dosing for patients who weigh less than 50 kg?
For patients weighing less than 50 kg (110 lb): Give Injectafer in two doses separated by at least 7 days. Give each dose as 15 mg/kg body weight.1 Learn more about Injectafer, the only IV iron that delivers up to 1500 mg in 2 administrations, separated by at least 7 days.
Can Injectafer be administered by IV push instead of infusion?
Yes. Injectafer may be administered as an undiluted slow intravenous push. Give at the rate of approximately 100 mg (2 mL) per minute.1
Are there any special precautions to keep in mind when administering Injectafer?
Injectafer should only be administered when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions.1
How often can patients be retreated with Injectafer?
Injectafer treatment may be repeated if iron deficiency anemia reoccurs, based on the clinical judgment of the health care provider. Note that in 24 hrs following administration of Injectafer, laboratory assays may overestimate serum iron and transferrin bound iron by also measuring the iron in Injectafer. Injectafer doses must be separated by at least 7 days.1
How should Injectafer be stored prior to use?
Store at 20°C to 25°C (68°F to 77°F) excursions permitted to 15°C to 30°C (59°F to 86°F). Do not freeze.1
What should I do if extravasation occurs?
Monitor for extravasation, and if it occurs, discontinue the Injectafer administration at that site immediately.1
What are the most common side effects of Injectafer?
- The most common side effects of Injectafer in the clinical trials (reported in ≥2% of study patients) were: nausea (7.2%); hypertension (3.8%); flushing/hot flush (3.6%); blood phosphorus decrease (2.1%); and dizziness (2.0%)
- In clinical trials, serious anaphylactic/anaphylactoid reactions were reported in 0.1% (2/1775) of subjects receiving Injectafer
- The pivotal trials for Injectafer did not exclude patients with a history of iron intolerance or drug allergies (with the exception of known hypersensitivity to study treatments)
For eligible patients, coverage is available as a medical benefit under most commercial health insurance plans.
Note that Injectafer prescriptions require a primary ICD-10-CM code for IDA as well as a secondary code for the underlying condition causing IDA.

Important Safety Information
Injectafer® (ferric carboxymaltose injection) is indicated for the treatment of iron deficiency anemia (IDA) in adult patients who have intolerance to oral iron or have had unsatisfactory response to oral iron, or who have non-dialysis dependent chronic kidney disease.
IMPORTANT SAFETY INFORMATION
Injectafer is contraindicated in patients with hypersensitivity to Injectafer or any of its inactive components.
WARNINGS AND PRECAUTIONS
Symptomatic hypophosphatemia requiring clinical intervention has been reported in patients at risk of low serum phosphate in the postmarketing setting. These cases have occurred mostly after repeated exposure to Injectafer in patients with no reported history of renal impairment. Possible risk factors for hypophosphatemia include a history of gastrointestinal disorders associated with malabsorption of fat-soluble vitamins or phosphate, concurrent or prior use of medications that affect proximal renal tubular function, hyperparathyroidism, vitamin D deficiency and malnutrition. In most cases, hypophosphatemia resolved within three months.
Monitor serum phosphate levels in patients at risk for low serum phosphate who require a repeat course of treatment.
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. In clinical trials, serious anaphylactic/anaphylactoid reactions were reported in 0.1% (2/1775) of subjects receiving Injectafer. Other serious or severe adverse reactions potentially associated with hypersensitivity which included, but were not limited to, pruritus, rash, urticaria, wheezing, or hypotension were reported in 1.5% (26/1775) of these subjects.
In clinical studies, hypertension was reported in 3.8% (67/1775) of subjects. Transient elevations in systolic blood pressure, sometimes occurring with facial flushing, dizziness, or nausea were observed in 6% (106/1775) of subjects. These elevations generally occurred immediately after dosing and resolved within 30 minutes. Monitor patients for signs and symptoms of hypertension following each Injectafer administration.
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.
In two randomized clinical studies, a total of 1775 patients were exposed to Injectafer, 15 mg/kg of body weight, up to a single maximum dose of 750 mg of iron on two occasions, separated by at least 7 days, up to a cumulative dose of 1500 mg of iron. Adverse reactions reported by ≥2% of Injectafer-treated patients were nausea (7.2%); hypertension (3.8%); flushing/hot flush (3.6%); blood phosphorus decrease (2.1%); and dizziness (2.0%).
The following adverse reactions have been identified during post approval use of Injectafer. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The following adverse reactions have been reported from the post-marketing spontaneous reports with Injectafer: cardiac disorders: tachycardia; general disorders and administration site conditions: chest discomfort, chills, pyrexia; metabolism and nutrition disorders: hypophosphatemia; musculoskeletal and connective tissue disorders: arthralgia, back pain, hypophosphatemic osteomalacia (rarely reported event); nervous system disorders: syncope; respiratory, thoracic and mediastinal disorders: dyspnea; skin and subcutaneous tissue disorders: angioedema, erythema, pruritus, urticaria.
CLINICAL CONSIDERATIONS IN PREGNANCY
Untreated 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.
Severe adverse reactions including circulatory failure (severe hypotension, shock including in the context of anaphylactic reaction) may occur in pregnant women with parenteral iron products (such as Injectafer) which may cause fetal bradycardia, especially during the second and third trimester.
