Infed Drug Information

INFeD is indicated for treatment of adult and pediatric patients of age 4 months and older with documented iron deficiency who have intolerance to oral iron or have had an unsatisfactory response to oral iron. INFeD, an iron replacement product, is indicated for treatment of adult and pediatric patients of age 4 months and older with documented iron deficiency who have intolerance to oral iron or an unsatisfactory response to oral iron.

The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions Delayed Reactions Increased Risk of Toxicity in Patients with Underlying Conditions Iron Overload Fetal bradycardia The following adverse reactions associated with the use of INFeD were identified in clinical studies or postmarketing reports. Because some of these reactions were 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. Blood and lymphatic system disorders : Leukocytosis, lymphadenopathy.

Gastrointestinal disorders : Abdominal pain, nausea, vomiting, diarrhea. General disorders and administration site conditions : chest pain, chest tightness, weakness, malaise, febrile episodes, chills, shivering, sterile abscess, atrophy/fibrosis (intramuscular injection site), brown skin and/or underlying tissue discoloration (staining), soreness or pain at or near intramuscular injection sites, swelling, inflammation. Musculoskeletal and connective tissue disorders : Arthralgia, arthritis (may represent reactivation in patients with quiescent rheumatoid arthritis – , myalgia, backache.

Ne rvous system disorders : Convulsions, seizures, syncope, headache, unresponsiveness, paresthesia, dizziness, numbness, unconsciousness, altered taste. P sy chiatric disorders : Disorientation Respiratory, thoracic and mediastinal disorders : Respiratory arrest, dyspnea, bronchospasm, wheezing. Renal and urinary disorders : Hematuria.

Skin and subcutaneous disorders : Urticaria, pruritus, purpura, rash, sweating. Cardiovascular disorders : Cardiac arrest, tachycardia, bradycardia, arrhythmias, acute myocardial ischemia with or without myocardial infarction or with in-stent thrombosis in the context of a hypersensitivity reaction, cyanosis, shock, hypertension, hypotension, flushing (flushing and hypotension may occur from too rapid injections by the intravenous route), local phlebitis at or near intravenous injection site. Most common adverse reactions are nausea, vomiting, chest pain, backache, hypersensitivity, dyspnea, hypotension, pruritus, flushing, dizziness.

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.

Pregnancy Risk Summary Parenteral iron administration may be associated with hypersensitivity reactions , 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.

Pediatric Use INFeD is not recommended for use in infants under 4 months of age. 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.

INFeD is contraindicated in patients who have demonstrated a previous hypersensitivity to iron dextran . Known hypersensitivity to INFeD

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 . INFeD is not removed by hemodialysis .
