Pfizer Canada has advised Health Canada that, in a very small number of cases, some EpiPen (0.3 mg) and EpiPen Jr (0.15 mg) auto-injector devices may not slide out of their carrier tube easily, or at all. This could delay or prevent emergency treatment, possibly leading to patient disability or death.

According to the company, the device label has been improperly applied to a very small number of devices in a way that the device label may become stuck to the inside of the carrier tube. This could mean that the device does not slide out of the tube as easily as expected. The issue is with the device label, and not with the device itself or the drug that it delivers (epinephrine).

EpiPen and EpiPen Jr are used to deliver an emergency treatment of adrenaline (epinephrine) to patients who are at risk or have a history of life-threatening allergic reactions (anaphylaxis).

Products are not being recalled by Pfizer, as the risk can be mitigated easily by pharmacists and patients by checking devices before an emergency situation arises to make sure they slide easily out of their carrier tube.
