What is anaphylaxis emergency treatment done with?

Anaphylaxis is a rapidly developing allergic reaction that can affect breathing, the airway, and circulation. Adrenaline helps open narrowed airways, reduce swelling, and support blood pressure. It should be given promptly when anaphylaxis is suspected; waiting for a rash or for every symptom to appear can be dangerous. Signs may include throat or tongue swelling, wheezing, difficulty breathing, sudden weakness, dizziness, fainting, or widespread allergic symptoms.

Emergency clinicians may provide oxygen, fluids through a vein, and other medicines or treatments based on the person's breathing and circulation. These do not replace adrenaline when anaphylaxis is suspected. The person needs observation because symptoms may return after initial improvement.

Use an available adrenaline auto-injector according to its instructions and call emergency services. Keep the person lying down with legs raised when possible. If breathing is difficult, allow a supported sitting position with legs extended, but do not let the person stand or walk. If symptoms continue or return and another device is available, follow the emergency plan or responder instructions. Tell responders about the suspected trigger, the symptoms, and the time adrenaline was given.

Call emergency services immediately for suspected anaphylaxis, especially with breathing difficulty, throat swelling, collapse, confusion, or marked dizziness. Do not drive yourself after using adrenaline. If the auto-injector is unavailable, call for emergency help and follow dispatcher instructions. After recovery, arrange follow-up to identify triggers, replace used devices, and update the written emergency plan.
