Anaphylaxis is the name given to a severe allergic reaction. Allergies to peanuts and tree nuts are the most common trigger for such reactions, but a number of other allergens can cause anaphylaxis, including milk, egg, fish, sesame, soya, penicillin, latex, kiwi fruit and insect stings. It can be life-threatening if it is not treated quickly with adrenaline.
Extremely serious allergic reactions like anaphylaxis can happen in minutes and can be fatal. There have been several cases of children experiencing fatal anaphylaxis and dying when at school.
The symptoms can vary considerably. Milder reactions can involve itchiness or swelling in the mouth, an uncomfortable skin rash, sickness or nausea. Serious symptoms include a severe drop in blood pressure, in which the person affected becomes weak and debilitated, severe asthma, or swelling which causes the throat to close.
Other symptoms which may be present during anaphylaxis are:
- flushing of the skin
- hives
- mounting fearfulness
- difficulty in swallowing or speaking
- changes in heart rate
- stomach pain
- collapse and unconsciousness
Anaphylaxis is treated with adrenaline – also known as epinephrine. This is available on prescription in the form of pre-loaded adrenaline auto-injectors or ‘pens’, the most common being the ‘EpiPen’. In the event of a severe allergic reaction, adrenaline should be injected into the muscle of the upper outer thigh, and an ambulance should be called. Milder reactions are sometimes treated with an antihistamine such as Piriton. In any case, careful vigilance should be maintained, as mild symptoms are often the sign that a serious reaction is imminent.
It is important that schools are always prepared to respond appropriately in an emergency, especially with 20% of reactions happening at school. The impact of a serious allergic reaction is long-lasting and doesn’t just affect the student. The impact will ripple through the school community and leave an emotional impact on the staff who dealt with the situation. By training staff and creating an allergy-aware environment, students and staff will be safeguarded.
In 2026, ‘Benedict’s Law’ was enacted which placed various responsibilities on schools, including:
- A dedicated allergy safety policy under a named senior lead
- Individual Healthcare Plans (IHCPs) for pupils with allergies requiring them
- Training for all staff on allergy awareness, emergency response and safe handling of adrenaline auto-injectors (AAIs)
- Spare AAIs on-site for use in an emergency
- Accurate recordings of serious allergy incidents and near misses
- Improved consistency and inclusion for children and young people with allergies.
Free resources on becoming compliant with the new statutory guidance are available from the Natasha Allergy Research Foundation (NARF) via their Allergy School
The Model Policy for Allergy Management at School provides a thorough introduction to writing an allergy policy in an easy-to-follow format.
Remember that schools can legally purchase spare AAIs without a prescription for use in emergencies.

The Benedict Blythe Foundation was established in memory of five-year-old Benedict Blythe, who tragically died following a severe allergic reaction at school. The Foundation works to make schools safer for children with allergies by campaigning for national reform, including the introduction of Benedict’s Law to ensure every school has allergy policies, staff training, and access to lifesaving medication.

Allergy School is the new, free educational programme by The Natasha Allergy Research Foundation, the UK’s food allergy charity. Aimed at nurseries, primary and secondary schools and out-of-school clubs and groups, the £1million initiative offers a suite of resources to transform understanding of food allergies in schools so that children with food allergies feel empowered, included and protected. Allergy School offers free resources for pupils and teachers, City & Guilds-accredited allergy training for teachers, and the programme is endorsed by the Department for Education.
