The medicines regulator has told patients to return Emerade 300 and 500 microgram adrenaline pens over fears some may fail to or prematurely activate if dropped.

Patients, or carers of patients, should "immediately" contact their GP, obtain a prescription for, and be supplied with, an alternative brand before returning the Emerade auto-injector pens, the Medicines and Healthcare products Regulatory Agency said.

Data from medical experts Open Prescribing, shared by the regulator, shows the Emerade pens were prescribed 20,256 times in England between March 2022 and February 2023.

Pharmacies can also help with obtaining new prescriptions and dispensing new pens, which will either be EpiPen or Jext brands.

Patients should ensure they know how to use replacements as brands work differently, the MHRA said.

The "precautionary recall" comes as activation failure and premature activation were detected, during a design assessment conducted by the manufacturer, in "some" 300 and 500 microgram Emerade auto-injector pens that had been dropped.

The activation issues could lead to a dose of adrenaline failing to be delivered or delivered too early.

The regulator also warned that exposure to temperatures above 25C may increase the risk of pen failure and urged people not to place Emerade pens near a radiator or fire.

Dr Alison Cave, MHRA chief safety officer, said: "Patient safety is our top priority.

"We are taking prompt action to protect patients, following detection of damage to internal components of the Emerade pens if they are dropped, which may mean they activate too early or fail to activate and deliver adrenaline.

"The Department for Health and Social Care has confirmed that there are appropriate supplies of EpiPen or Jext adrenaline pens available for patients across the UK, however, patients will need to request a new prescription.

"Patients are reminded to carry two pens with them at all times as normal and to contact their healthcare professional when a replacement is due."

Emerade is a brand of adrenaline auto-injector pen for the emergency treatment of anaphylaxis.
