Peanut allergy PLAN (peanut allergy emergency plan)
General guidance for recognising and responding to severe allergic reactions
People with peanut allergy can experience rapid‑onset reactions, including anaphylaxis. Every patient should have a personalised emergency plan created by an allergy specialist. The information below explains general principles only
Why Specialist Plans Matter
A personalised plan from an allergy consultant provides:
- clear instructions for mild vs severe symptoms
- guidance on antihistamines and adrenaline
- advice for schools, workplaces and travel
- training on recognising early warning signs
- support for families and carers
Our clinic offers consultant‑led peanut allergy assessment, including molecular testing (Ara h 1–9), risk stratification and personalised emergency plans.
Recognising a Serious Reaction
Symptoms that require urgent attention include:
- swelling of lips, tongue or throat
- difficulty breathing or wheezing
- chest tightness
- dizziness or feeling faint
- rapid progression of symptoms
These may indicate anaphylaxis, a medical emergency.
If Accidental Exposure Occurs
General steps commonly included in clinician‑approved action plans:
- stop eating immediately
- stay with another adult
- sit or lie down to reduce risk of fainting
- monitor for breathing or throat symptoms
- follow your personalised plan from your allergy specialist
If You Have Been Prescribed an Adrenaline Auto‑Injector
People who carry an adrenaline device should be trained by a clinician on when and how to use it.
General principles taught in specialist clinics include:
- use the device if symptoms affect breathing, voice, throat or circulation and if you develop any chest pain, shortness of breath, choking sensation or feeling faint
- call emergency services dialling 999 after using adrenaline
- attend the nearest emergency department for observation
