Some EpiPens May Be Faulty, Health Canada Warns

The devices may not slide out of their tubes easily.

OTTAWA — Health Canada is warning that some EpiPens may not slide out of their tubes easily, possibly delaying emergency treatment.

The agency says it was advised by Pfizer Canada about the issue, which it says affects some EpiPen and EpiPen Jr auto-injector devices.

Health Canada warns that the problem could delay or prevent emergency treatment, possibly leading to patient disability or even death.

Pfizer Canada says the issue is with the device label, and not with the device itself or the drug it delivers.

EpiPens are used to deliver a dose of adrenaline to patients who are at risk of life-threatening allergic reactions.

Health Canada says the products are not being recalled by Pfizer, as the risk can be easily mitigated by simply checking the devices to make sure they slide easily out of their carrier tube.

According Pfizer, there have been no reports of EpiPen malfunctions in Canada.

CORRECTION - Sept. 30, 2018: An earlier version of this story featured a photo of a hand grasping the epipen with thumb on top. Several warnings advise against this due to risk of accidental injection into one's thumb. The photo has been replaced.
