PUBLIC COMMUNICATION - Health Canada Endorsed Important Safety Information on FERAHEME (ferumoxytol)

July 11, 2014

Subject: Important new restrictions on the use of FERAHEME® (ferumoxytol) due to information on serious allergic reactions

Takeda Canada Inc., in collaboration with Health Canada, would like to inform you of important new restrictions on the use of FERAHEME® due to information on serious allergic reactions.

FERAHEME® (ferumoxytol) is an iron product that is given by injection into a vein. It is authorized in Canada for the treatment of iron deficiency anaemia in adult patients with chronic kidney disease (CKD).

  • FERAHEME® should no longer be used in patients who are allergic to other iron products given by injection or infusion, or in patients with multiple drug allergies.
  • Patients are also reminded that:
    • allergic reactions including life-threatening and sometimes fatal reactions (anaphylaxis) have occurred with the use of FERAHEME®.
    • FERAHEME® should only be given in a setting where appropriate personnel and therapies for the treatment of severe allergic reactions are also immediately available.

Among Canadian patients who experienced serious allergic reactions immediately after treatment with FERAHEME®, some had already had allergies to other iron products given by intravenous injection, or multiple (two or more) drug allergies. Also, the safety of using FERAHEME in these patients has not been studied. Therefore, patients with any allergy to other iron products given by injection or infusion, or with multiple (two or more) drug allergies may be at increased risk of allergic reactions associated with FERAHEME®; FERAHEME® should not be used in these patients.

Takeda Canada Inc. has worked with Health Canada to update the safety information for FERAHEME® and has sent a letter to health care professionals to inform them of this new safety information.  A copy of that letter is available on the Health Canada Web site.

The newly revised Product Monograph for FERAHEME® (ferumoxytol), which includes the above-mentioned information, can be accessed on the Web sites of Health Canada and Takeda Canada Inc.

Managing marketed health product-related side effects depends on health care professionals and consumers reporting them. Any case of serious allergic reactions or other serious or unexpected side effects in patients receiving FERAHEME® should be reported to Takeda Canada Inc. or Health Canada.
