Anaphylaxis is a severe and potentially life-threatening allergic reaction that can develop very quickly. Immediate recognition and treatment are essential to prevent serious harm or death.
If a child with a known allergy suddenly becomes unwell, especially with breathing difficulties, always assume anaphylaxis and act immediately.

You do not need to see all of these symptoms to suspect anaphylaxis. Symptoms can worsen quickly, so act immediately.
