Novel Technique for Epinephrine Removal in New Generation Autoinjectors.

Anaphylaxis is a severe, life-threatening, multisystem hypersensitivity reaction that can rapidly progress to hypotension and airway compromise. Successful management of anaphylaxis has been documented with the use of prescription intramuscular epinephrine pens that require only minimal training for safe use. The prior generations of these commercially available autoinjectors were produced for single use; however, safe removal of multiple doses has been demonstrated for use in dire situations.
