Adrenaline auto-injector. Used to treat anaphylaxis

How it works

What is Jext?

Jext is a brand of adrenaline (epinephrine) auto-injectors. It’s a device that contains adrenaline that’s designed to be easy to inject in emergencies. It’s used for the emergency treatment of severe allergic reactions (anaphylaxis).

How it works

Jext pens work by delivering adrenaline into the body with an injection. This works on the respiratory system and the cardiovascular system to stop the serious effects of anaphylaxis.


The recommended dose for adults and children who weigh over 30kg is Jext 300mcg injected into the outer thigh for allergic emergencies. It’s recommended that children who weigh between 15kg and 30kg use Jext 150mcg for allergic emergencies. At Simple Online Pharmacy, we only offer the 300mcg strength for use in adults over 18 years old.
