Schools may administer their “spare” adrenaline auto-injector (AAI), obtained, without prescription, for use in emergencies, if available, but only to a pupil at risk of anaphylaxis, where both medical authorisation and written parental consent for use of the spare AAI has been provided.The school’s spare AAI can be administered to a pupil whose own prescribed AAI cannot be administered correctly without delay.AAIs can be used through clothes and should be injected into the upper outer thigh in line with the instructions provided by the manufacturer.If someone appears to be having a severe allergic reaction (anaphylaxis), you MUST call 999 without delay, even if they have already used their own AAI device, or a spare AAI.In the event of a possible severe allergic reaction in a pupil who does not meet these criteria, emergency services (999) should be contacted and advice sought from them as to whether administration of the spare emergency AAI is appropriate.
