Health Canada Endorsed Important Safety Information on FERAHEME (ferumoxytol)
November 21, 2014
Dear Health Care Professional:
Subject: New important changes to the delivery of FERAHEME® (ferumoxytol) and to restrictions of use to further mitigate risks of serious hypersensitivity reactions
Further to Takeda Canada’s recent communication of July 11, 2014, in collaboration with Health Canada, Takeda would like to inform you of the following important new changes on the use of FERAHEME® (ferumoxytol), an intravenous (IV) iron product, authorized in Canada for the treatment of iron deficiency anemia in adult patients with chronic kidney disease (CKD).
The Product Monograph (PM) is being revised to reflect the following in an effort to further reduce the risk of serious hypersensitivity reactions due to FERAHEME®:
- FERAHEME® should only be administered as an intravenous infusion in 50-250 ml of 0.9% sterile sodium chloride or 5% sterile dextrose over a minimum period of 15 minutes following dilution and must no longer be administered by direct injection of the undiluted product.
- Patients should be closely monitored for signs and symptoms of hypersensitivity reactions including monitoring of blood pressure and pulse during and for at least 30 minutes following each infusion of FERAHEME®.
- FERAHEME® is contraindicated in patients with any known history of drug allergy.
- Elderly patients (> 65 years of age) or patients with multiple co-morbidities who experience a serious hypersensitivity reaction due to FERAHEME® may have more severe outcomes. The potential risks and benefits of FERAHEME® administration should be carefully considered in these patients.
In addition, the revised PM will recommend that patients be placed in a reclined or semi-reclined position during infusion and for at least 30 minutes thereafter.
The change of administration from a rapid IV injection to an infusion may reduce the risk of serious hypersensitivity reactions including life-threatening and fatal outcomes reported in the post-market setting, and allow healthcare professionals to better intervene at the first signs of prodromal symptoms of hypersensitivity.
The FERAHEME® dilution should be used immediately. If you have questions on the infusion process, please contact Takeda Canada Inc.
FERAHEME® is currently contraindicated in patients with any allergies to parenteral iron products or with multiple (two or more) drug allergies. Takeda will now expand this contraindication to include patients with any known history of drug allergy.
In CKD clinical studies, serious hypersensitivity reactions were reported in 0.2% (3/1642) of patients receiving FERAHEME®. In non-CKD clinical studies, serious hypersensitivity reactions were reported in 0.6% (6/1014) of patients who received FERAHEME®. In a non-CKD clinical study, moderate to severe hypersensitivity reactions were reported in 2.5% (10/406) of patients treated with FERAHEME® and in 1.0% (2/199) treated with iron sucrose.
FERAHEME® should only be administered when personnel and therapies are immediately available for the treatment of anaphylaxis and other hypersensitivity reactions.
Managing marketed health product-related adverse reactions depends on health care professionals and consumers reporting them. Reporting rates determined on the basis of spontaneously reported post-marketing adverse reactions are generally presumed to underestimate the risks associated with health product treatments. Any case of serious hypersensitivity or other serious or unexpected adverse reactions in patients receiving FERAHEME® should be reported to Takeda Canada Inc. or Health Canada.
