FDA, Pfizer EpiPen Caution
FDA says patients, caregivers, and healthcare professionals should be aware that EpiPen 3.0mg and EpiPen Jr 0.15mg and their authorized generic versions may potentially have delayed injection or be prevented from properly injecting. The agency notice says problems can be due to (1) device failure from spontaneous activation caused by sideways force to remove the blue safety release; (2) device failure from inadvertent or spontaneous activation due to a raised blue safety release; (3) difficulty removing the device from the carrier tube; or (4) user errors.
The notice links to a letter from Pfizer to healthcare professionals that explains each of the potential problems in detail and says it is important for healthcare providers, patients, and caregivers to periodically review the EpiPen user instructions and practice using the EpiPen trainer to ensure proper understanding and use of the EpiPen auto-injector.
“Since EpiPen is administered for severe and potentially life-threatening allergic reactions, anything that prevents or delays the administration of the intended dose of epinephrine could result in a high risk to the patient, including the risk of death,” Pfizer says.
