A Review of Auto-Injector Pen Safety and Preventative Strategies

Abstract

Reports of auto-injector pen injuries have increased over the past decade. However, the true incidence of these injuries is unknown. We present the case of an accidental digital self-injection by a dermatologist whilst he was trying to administer the medication to a patient presenting with anaphylaxis as an example of a typical auto-injector injury. Additionally, we discuss safety issues, commonly reported injuries of accidental self-injection, and review the safety guidelines for use of a common auto-injector pen. Finally, we explore common barriers to proper auto-injector handling and suggested preventative strategies in order to decrease injuries caused by auto-injectors.

The true incidence of accidental EAI injections is unknown, but has been reported to be increasing [ 4 ]. In therapeutic doses, epinephrine can result in adverse complications, such as dizziness, anxiety, headache, restlessness, tremor, pallor, numbness, and palpitations.…”
