Are allergy pens long enough? study measures thigh depth to find out

Summary
This study looked at 107 people with severe food or insect allergies to measure the distance from skin to muscle in their thighs. The goal was to see if the needles on common epinephrine auto-injectors (like EpiPen) are long enough to deliver the medicine into the muscle, as recommended. Researchers used ultrasound to take these measurements. The findings could help improve injector design so that life-saving epinephrine reaches the right spot during an allergic emergency.
