School allergy care
Mild to moderate reactions are usually responsive to an antihistamine.
These are usually in syrup or tablet form. They work by blocking the action of a chemical called histamine in the body. However, a mild reaction can worsen, sometimes even hours after initial symptoms. So, the child should always be monitored for signs of anaphylaxis; this is a potentially life-threatening allergic reaction affecting the airway, breathing and consciousness level.
Antihistamines are ineffective in severe reactions. They should NOT be used as the first line treatment for anaphylaxis.
See next for the management of a severe allergic reaction/anaphylaxis.
Staff should always document when a dose of antihistamine is given and inform parents/carers. A further dose of antihistamines can be offered in case of vomiting.
Children experiencing mild to moderate reactions who respond well to antihistamines are unlikely to require urgent medical attention and don’t need to be sent home, however should be monitored for the rest of the day.
Parents/carers should be informed once antihistamines are given.
