Cases of severe allergic reactions to triggers, for example food or bites and stings, can lead to anaphylaxis. Anaphylaxis is very serious and can be fatal.

If you think someone is having an allergic reaction, call triple zero (000).

Symptoms of anaphylaxis may include:

  • difficult or noisy breathing
  • difficulty talking and/or hoarse voice
  • a swollen tongue
  • persistent dizziness or collapse
  • swelling or tightness in the throat
  • pale and floppy (young children)
  • wheeze or persistent cough

First aid for anaphylaxis

  1. Lay person flat and keep them still – don't let them stand or walk.
  2. If unconscious, place them in the recovery position.
  3. If breathing is difficult allow them to sit.
  4. Give adrenaline autoinjector.
  5. Phone ambulance on triple zero (000).
  6. Further adrenaline doses may be given if no response after 5 minutes.
  7. Transfer person to hospital for at least 4 hours of observation.

If the person is unresponsive and not breathing normally, start CPR.

If you aren't sure – always give the adrenaline autoinjector. If the person also has asthma, give the adrenaline autoinjector first and then asthma reliever puffer.

People with diagnosed allergies should avoid all triggers and confirmed allergens and have a readily accessible anaphylaxis action plan and medical alert device. It’s wise to ensure your friends and family know how to follow your anaphylaxis action plan too in case you need help.

Adrenaline for severe allergies - Australasian Society of Clinical Immunology and Allergy (ASCIA)

Adrenaline (epinephrine) is a natural hormone released in response to stress. When injected, adrenaline rapidly reverses the effects of anaphylaxis by reducing throat swelling, opening the airways, and maintaining heart function and blood pressure. Anaphylaxis is a potentially life threatening, severe allergic reaction and should always be treated as a medical emergency. Adrenaline injected into the outer mid-thigh muscle is the first line treatment for anaphylaxis.

Allergic reactions to bites and stings - Australasian Society of Clinical Immunology and Allergy (ASCIA)

Most insect bites and stings result in a localised itch and swelling that settles within a few days. Severe allergic reactions (anaphylaxis) to insects are usually due to bees, wasps or the Australian Jack Jumper ant. Insect bites are a less common cause of anaphylaxis than insect stings. Fortunately, effective treatments are available to treat allergic reactions to bites and stings.
