What does anaphylaxis emergency treatment treat?

Anaphylaxis can cause swelling of the face, lips or tongue, tightness in the throat, wheezing, shortness of breath, dizziness, collapse, widespread hives, vomiting or sudden weakness. It may begin after food, a medicine, an insect sting or another trigger. Adrenaline is the key emergency medicine because it helps open the airways, reduce swelling and support blood pressure.

An adrenaline auto-injector is designed for rapid use when anaphylaxis is suspected. Emergency teams may provide further treatment and observation because symptoms can return after they first improve. The treatment does not remove the underlying allergy or replace assessment of the trigger.

Use the prescribed adrenaline auto-injector promptly when anaphylaxis is suspected, following its instructions, and call emergency services immediately. Keep the person lying down if possible; raise the legs unless breathing is difficult, when sitting slightly upright may help. Do not leave the person alone, and do not give food or drink if swallowing is unsafe. A second device may be needed only according to emergency guidance.

Treat facial swelling, throat tightness, shortness of breath, faintness or rapidly spreading allergic symptoms as an emergency. Call for urgent help even if the person improves after adrenaline, because monitoring and additional treatment may be needed. After recovery, arrange follow-up to review the suspected trigger and an emergency action plan.

Ask how to recognise your early warning symptoms, where to keep your auto-injector, when to carry more than one, and how family members or colleagues should help. Ask whether allergy assessment and written emergency instructions are appropriate.
