Can you have an allergic reaction to epinephrine in school?
Up to 25% of severe allergic reactions that occur on school campuses happen to people who are experiencing their very first anaphylaxis reaction. Since these people (children, staff and visitors) have not been previously diagnosed with allergies, they may not have their own epinephrine auto-injectors on hand. Most states have passed legislation to allow schools to stock undesignated epinephrine as a part of their emergency medical kits. This allows specified staff to treat someone suffering anaphylaxis, even for their very first allergic reaction. Many states are looking beyond the classroom to other areas where food allergy triggers could be present. In any public space where food is present – such as sports and recreation venues, summer camps, amusement parks, movie theaters – there is a risk for an allergic person to come in contact with their allergen.
