Supply of Jext® (adrenaline as tartrate) 150 mcg and 300 mcg Adrenaline Auto-Injector

As you are probably aware there is currently a shortage of adrenaline auto-injectors in the UK. This shortage has been caused by intermittent supply issues of another adrenaline device and is affecting most countries in Europe.  It is anticipated that supply will stabilise in the fourth quarter (October to December) of 2018.  The supply status will be continuously reviewed 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.

ALK is working closely with its UK distribution partner Alliance Healthcare to ensure equitable distribution of supplies but it is likely that Jext® 150 mcg and Jext® 300 mcg will not be available at all times.

Extended Use Beyond Labelled Expiry Date for Selected Lots of Jext® 150 mcg and 300 mcg Adrenaline Auto-Injectors

To further ease the situation, ALK has obtained acceptance from the UK medicines regulator, the Medicines and Healthcare Products Regulatory Agency (MHRA), to extend the use of specific lot (batch) numbers of Jext® 150 mcg and Jext® 300 mcg auto-injectors, beyond the labelled expiry date by four months. The affected lot numbers are listed in the table below.
