Important: the extended use only applies to the lots of Jext® 150 mcg and Jext® 300 mcg auto-injectors listed above.  Patients can continue to use the Jext® auto-injectors of these specified lots safely until the extended use by date as stated above.

This extended use does not apply to any other lot number of Jext® auto-injectors not specified. Patients must continue to adhere to the labelled expiry date on any Jext® auto-injector not covered by the lot numbers above.

Further information on the extended use of the listed lots of Jext® autoinjectors

You may be aware of the recent supply issues affecting some brands of adrenaline auto-injectors, which have resulted in increased demands on alternative brands of auto-injectors including Jext®. The overall market supply of adrenaline auto-injectors is being monitored by the Department of Health and Social Care.

ALK is working hard to help address the situation and has significantly increased production of its Jext® 150 mcg and 300 mcg adrenaline auto-injectors at its European manufacturing facility. However, due to the time needed for manufacture and the magnitude of the current deficit, it is not possible for ALK to completely meet the shortfall in supply in the short term.

To further ease the shortfall, the period that 40 specific lots of Jext® 150 mcg and Jext® 300 auto-injectors (listed above) can be used has been extended by 4 months beyond the labelled expiry date on the pack.

Lot numbers and labelled expiry dates are marked on the end-flap of the box and on the auto-injector label itself.

This extended use of 4 months beyond the labelled expiry date for the specific lots is based on supportive stability data for Jext® auto-injectors and has been reviewed by the MHRA.  The Jext® auto-injectors of these specific lots will continue to work safely and as intended within the allowed extended use by date.  The Jext® auto-injectors should continue to be stored as labelled on the pack.

At the end of the extended use period (the end of the month listed in the right column of the table above), a new auto-injector will still need to be obtained.

Further information on recommendations to healthcare professionals

  • Tell patients and caregivers about the extended use by date of the specified lots of Jext® 150 mcg and 300 mcg auto-injectors as listed above.  This does not apply to other lots of Jext® auto-injectors not listed.
  • Show patients and caregivers where to find the lot numbers on their device (on the end-flap and if necessary, on the device label itself) and encourage them to sign up for the Expiry Alert Service.
  • Reassure patients and caregivers that their device will continue to work safely over the extended use period.
  • Remind patients and caregivers that they should still obtain a new device near the end of the extended use period.
  • Advise patients to continue to check periodically the viewing window in the label of their device to ensure the liquid inside is clear and colourless.  Do not use the device if the liquid is discoloured.

This announcement regarding the extended use of certain batches supersedes any notification that a patient may receive via the expiry alert service from www.jext.co.uk. If you require additional information or have any questions, please contact ALK Customer Services: 0118 903 7940.
