Around 250,000 adrenaline injectors will expire in December and January. Currently, 210,000 patients in the UK are prescribed adrenaline injectors.
The Anaphylaxis Campaign is encouraging patients to 'check and carry' - to check the device has not expired and carry it at all times.
The campaign is being supported by ALK-Abello, the manufacturer of the Epipen adrenaline injector. Research has shown that around a third of people prescribed adrenaline injectors are likely to have an out-of-date device, the company said.
