Allergy sufferers have been told they can use their EpiPens beyond the normal use-by date, amid short supply.
The expiry date of a number of EpiPens has been extended by up to four months in line with advice from the medicines regulator.
EpiPens are the most common Adrenaline Auto-Injectors (AAIs) are usually good for use for 12 months.
But an “interruption in production” has led manufacturer Mylan UK to extend usage of nine lots of Epipen 0.3mg with original expiry dates between July 2018 and November 2018.
Mylan reassured users that continued use of the device is safe for the length of the extended period and supporting data has been reviewed by the Medicines and Healthcare products Regulatory Agency (MHRA).
The extension does not apply to EpiPen Junior 0.15mg usually given to children.
AAIs have faced a global shortage in recent months.
The MRHA this week alerted that the manufacturer is out of EpiPen Junior devices and supply will be limited in the coming months.
It is hoped the manufacturing shortage will be resolved between October and November this year.
The medical device is used in emergencies to help stop a serious allergic reaction from becoming life-threatening.
It is used for severe reactions caused by certain foods, insects stings and exercise.
Users are normally advised to carry two devices with them in case one is not enough.
The move comes in the week of an inquest into the death of Natasha Ednan-Laperouse, who suffered a fatal allergic reaction to a Pret sandwich containing sesame, despite receiving two EpiPen injections.
