What is Jext®?

Jext® is a single-use adrenaline auto-injector pen. Each Jext® injects a premeasured single dose of adrenaline for the emergency treatment of anaphylaxis.

The needle is contained within the Jext® before use and is automatically covered by the black needle shield after use. Jext® has been designed to be simple and reliable.

Using Jext®

Your doctor should explain when and how to use your Jext®. If you begin to experience the symptoms of anaphylaxis it is important that you use your Jext® immediately.

Early use of adrenaline improves the outcome and recovery from anaphylaxis. If symptoms don’t improve or the original symptoms re-appear, a second Jext® can be used after about 5-15 minutes.

How to use Jext®

Why have I been prescribed Jext®?

You have been prescribed Jext® as you are at risk from a potentially life threatening allergic reaction called anaphylaxis (an-a-fil-axis). This is sometimes called anaphylactic shock or anaphylactic reaction.
