What should you know about epi for anaphylaxis?

Anaphylaxis is a rapidly developing, serious allergic reaction. It can cause swelling of the lips or tongue, trouble breathing, wheezing, throat tightness, faintness, confusion, or widespread hives. Epinephrine helps open the airways, support circulation and reduce the effects of the allergic reaction. It works best when given early; do not wait for every symptom to appear.

An auto-injector is a prefilled device designed to deliver epinephrine through the outer thigh. It may be used through clothing if necessary. A prescribed device should be carried wherever the person may encounter a known trigger, such as a food allergy.

Use the device according to its instructions as soon as anaphylaxis is suspected. Call emergency services immediately, say that anaphylaxis is suspected and state that epinephrine has been given. Keep the person lying down with legs raised when possible; let them sit with legs outstretched if breathing is difficult, and do not let them stand or walk.

If symptoms continue or return and another prescribed device is available, a second dose may be needed according to the emergency plan. Give the used device to the medical team. Antihistamines do not replace epinephrine for breathing or circulation problems.

Treat suspected anaphylaxis as an emergency, even if the person starts to feel better after epinephrine. Symptoms can return, so assessment and observation in an emergency setting are needed. Wheezing, throat swelling, breathing difficulty, collapse, or severe dizziness require immediate action.

Ask which device and dose are right for you, how to recognise your early warning signs, when a second device should be used, and how family members, teachers or colleagues can give it. Ask whether allergy testing and a written emergency plan are appropriate.
