Purpose: Reports on accidental auto-injection of adrenaline are few. We encountered three cases of accidental injection of adrenaline. In this study, we have examined and reported the clinical courses and symptoms of our cases. Case: Case 1 involved a female physician in her 50s who had attended an explanatory meeting on auto-injection of adrenaline. She mistook EpiPen® to be the EpiPen trainer and accidentally injected herself with 0.3mg EpiPen®. Her systolic/diastolic pressure peaked at 7 min to reach 144/78mmHg and decreased to 120/77mmHg at 14 min. Except for palpitation after 7 min, the only subjective symptom was local pain at the injection site. Case 2 was noted in a 6-year-old boy. He accidentally pierced his right forefinger with 0.15mg EpiPen®, and after 20 min, his right forefinger was swollen. The swelling improved 80 min after the accidental injection. Case 3 was noted in a 4-year-old girl. She accidentally injected herself with 0.15mg EpiPen®. Her systolic/diastolic pressure peaked at 23 min to reach 123/70mmHg and decreased to 96/86mmHg at 28 min. Discussion/Conclusion: Severe adverse effects of accidental auto-injection of adrenaline were not observed in these three cases. Our findings suggest that while handling adrenaline auto-injectors, we should keep in mind the possibility of accidental injection.
