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


    How does it work?
    Adrenaline works quickly to reverse the symptoms of an anaphylactic reaction. Adrenaline injected into the muscle of the front of the upper outer thigh is the first choice drug for the emergency treatment of anaphylaxis.
