Anaphylaxis is a life-threatening allergic reaction that can quickly compromise the airway and circulation, so recognizing it early is crucial. Signs include trouble breathing or speaking, swelling of the face, lips, tongue, or throat, wheezing or chest tightness, and widespread hives or flushing, often accompanied by dizziness, fainting, or a sense of impending doom. Because the reaction can deteriorate rapidly, the immediate field actions are to call emergency services right away and to administer epinephrine as soon as it’s available if the person has a prescribed auto-injector and you know how to use it. After giving epinephrine, keep the person lying flat with the legs supported unless they have trouble breathing or are vomiting, and monitor their airway, breathing, and pulse. Stay with them and seek ongoing medical care even if symptoms seem to improve, since a second reaction can occur. If an auto-injector isn’t available, still call for help and provide supportive care while monitoring the person.
