<<Disclaimer: Verify this information before applying it to your situation.>> Epi-pens are prescribed for severe allergic reactions that could possibly lead to death, i.e., bee stings and peanut allergies. It is a syringe containing epinephrine, to be injected into a person's thigh. My son has a severe peanut allergy and when he accidentally ingests peanuts, he vomits and swells all around the face, breaks out in hives and goes into an asthma attack. I can't imagine how an epi-pen could help with a gluten reaction. Kathy Grzedzinski
