Asevere allergic reaction with airway and/or breathing and/or circulation problems.
Causes can be –
- Food (commonest cause in children)
- Exercise (ask if wheat or fish eaten just prior to exercise, as very rarely can be food – induced exercise anaphylaxis)
- Drugs (no need to refer if single drug and alternative available eg penicillin allergy)
- Venom induced (most commonly bee or wasp)
Refer all cases to Paediatric Allergy Clinic (Consultant led)
Adrenaline Auto – injectors
In most cases where provoking allergen may be accidentally encountered again (or idiopathic), prescribe an adrenaline autoinjector when referring, due to small risk of recurrence in intervening wait for appointment. All makes of auto-injector are acceptable.
