Anaphylaxis is a medical emergency which must be treated quickly.
If someone has symptoms of anaphylaxis you should:
Use an adrenaline auto-injector (AAI) if available
Call 999 immediately
Remove trigger if possible
Make sure the person lies down or stays still
Administer a second AAI if there is no improvement in symptoms in 5 minutes
Recognise the symptoms
Symptoms of an allergic reaction usually develop within a few minutes of being exposed to the allergen. Symptoms will vary from person to person so it is important to discuss your symptoms with your doctor and be clear on what to look out for. Anaphylaxis usually develops suddenly and gets worse very quickly.
Severe allergic reaction (anaphylaxis) symptoms include:
Feeling lightheaded or faint
Breathing difficulties, such as fast, shallow breathing
A fast heartbeat
Confusion and anxiety
Collapsing or losing consciousness
Mild to moderate allergic reaction symptoms include:
Red, raised, itchy rash
Abdominal pain, nausea and/or vomiting
Itchy, red, watering eyes
