Making the Case for INFeD

Calculating Iron Needs and Dose of INFeD®

Iron deficiency anemia

Note: Iron deficiency anemia will not appear until essentially all iron stores have been depleted.

  • The total iron requirement for patients with iron deficiency anemia reflects:
    1. Amount needed to restore hemoglobin (Hb) concentration to normal or near normal levels2
    2. Amount needed to replenish iron stores in most individuals with moderately or severely reduced levels of Hb2
  • Therapy should aim to replenish both Hb iron and iron stores2

INFeD is indicated in the treatment of patients with documented iron deficiency in whom oral administration is unsatisfactory or impossible.

Important Safety Information

Anaphylactic-type reactions, including fatalities, have followed the parenteral administration of iron dextran injection. A test dose should be administered prior to the first therapeutic dose, followed by the full therapeutic dose if no signs or symptoms of anaphylactic-type reactions are seen. Resuscitation equipment and personnel trained in the detection and treatment of anaphylactic-type reactions must be readily available during all INFeD administrations. Patients should be observed for signs or symptoms of anaphylactic-type reactions during all INFeD administrations. Fatal reactions have followed the test dose and have also occurred in situations where the test dose was tolerated. Use INFeD only in patients in whom clinical and laboratory investigations have established an iron deficient state not amenable to oral iron therapy. Patients with a history of drug allergy or multiple drug allergies may be at increased risk of anaphylactic-type reactions. INFeD should be used with caution in individuals with histories of significant allergies and/or asthma, and is contraindicated in patients with hypersensitivity to the product and patients with all anemias not associated with iron deficiency. INFeD should be used with extreme care in patients with serious impairment of liver function, and should not be used during the acute phase of infectious kidney disease. Unwarranted therapy with parenteral iron will cause excess storage of iron with the consequent possibility of exogenous hemosiderosis, which is particularly apt to occur in patients with hemoglobinopathies and other refractory anemias.
