Batches of adrenalin injector pen recalled, says MHRA

  • Comment

Around 20 batches of Jext adrenalin injector pens have been recalled after a fault was discovered by the manufacturer.

The single-use adrenaline auto-injector is intended for the emergency treatment of anaphylaxis to insect stings or bites, foods, drugs and other allergens as well as exercise induced anaphylaxis.

Routine testing found the needles in these pens may have become bent, meaning it may not deliver the required dose of adrenalin when required.

Only a small number (0.04%) of the needles in the batches have been affected by the fault, according to the Medicines and Healthcare products Regulatory Agency.

Patients with injectors from the affected batches are advised to make an appointment with their general practice as soon as possible to switch to an alternative product. In the meantime, they are advised to continue to carry their existing injectors as prescribed.

Adam Burgess, head of the MRHA’s defective medicines reporting centre, said: “The number of needles affected by this is very small and we would advise people who use them to continue to carry them as normal.

“We have not had reports of any incidents with these but urge people to check the batch number and, if it is from an affected batch, make an appointment with their GP as soon as possible to discuss alternatives,” he added.
