How to CORRECTLY stab someone with an Epi-pen. My girlfriend has a peanut allergy and I really would love to live in a world where more people know the correct way to use that instrument. Step one: take off the cap (its blue) [this is the side that points away from their body] Step 1 1/2: make sure you won't hit their phone. Step two: stab that shit into their leg (upper outer thigh)(through any non super super thick pants is fine. Jeans = fine)[thumb holding the sides] {you stab them with the orange side} Step three: hold it there for 3 seconds (it used to say 10 seconds EMT guy in comments says FDA recently changed this to 3 seconds) Step four: call 911 (epi pens buy time not fix the problem entirely) DO NOT BE GENTLE! Bruises heal. Being gentle often causes a muscle twitch. Their reflex will be to jerk away, and if the needle comes out without giving them the dose, you can't just re-stab them. Hold their leg from the inside. Otherwise it could cause a large cut that almost always results in a scar associated with unpleasant memories. Also rub the injection site for a few seconds after you remove it from their skin. It will help get it into their blood stream faster.
