Expiry Alert Service
Tell your patients about our Free Expiry Alert Service.
Patients can’t rely on an out-of-date Adrenaline Auto-Injector. Auto-Injectors that are beyond their expiry date still contain adrenaline but the dose might be lower than that stated on the label and inversely proportional to the length of time past the expiry date1.
Ensure your patient registers their Jext® with the Expiry Alert Service.
Alerts will be sent:
4 Weeks
4 weeks prior to the expiration of your Jext®
2 Weeks
2 weeks prior to the expiration of your Jext®
Day after
The day after the expiration of your Jext®
When travelling to another country it’s important to keep to your Jext® action plan and make sure you take the same level of care with your condition as you do at home. Click below for some useful travel sheets to help you look after yourself abroad.
Committed to patient support
We have a range of resources available to help prepare and educate yourself and those around you about living with anaphylaxis.
Carry two jext pens
It is recommended you carry two Jext® pens with you at all times. Early use of adrenaline improves the outcome and recovery from anaphylaxis, but if symptoms don’t improve or the original symptoms re-appear, a second Jext® can be used after about 5-15 minutes.
About anaphylaxis
How to use Jext®
Step 1
Grasp the Jext® in your dominant hand (the one you use to write with) with your thumb closest to the yellow cap.
Step 2
Pull off the yellow cap with your other hand.
Step 3
Place the black injector tip against your outer thigh, holding the injector at a right angle (approx. 90°) to the thigh.
Step 4
Push the black tip firmly into your outer thigh until you hear a ‘click’ confirming the injection has started, then keep it pushed in. Hold the injector firmly in place against the thigh for 10 seconds (a slow count to 10) then remove. The black tip will extend automatically and hide the needle.
Step 5
Massage the injection area for 10 seconds. Seek immediate medical help.
