Remove the person from contact with the allergen, if the allergen is suspected to be something in the air or on the skin. Epinephrine is usually prescribed in an Anakit or Epipen with a preloaded syringe, and injected intramuscularly in the thigh for rapid absorption. Monitor airway, breathing and circulation. Treat for shock. Inject a second dose of epinephrine within 12 to 15 minutes after the first dose was administered, to prevent a relapse.
Most kits contain at least two doses.
Administer an oral antihistamine once the epinephrine has taken effect and the person is able to take the medication by himself or herself. Evacuate immediately, administering oral antihistamines at regular intervals until the person has reached professional medical care. See your doctor. Read the instructions accompanying an epinephrine kit and consult with a doctor for efficient strategies for administering an injection prior to participating in any wilderness activity. Find out what they are allergic to, where they keep their kit and how their injections are administered, so that you can assist them in an emergency situation.
