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).
It should be used as soon as you suspect a serious allergic reaction. It can be self-administered or administered by someone else who is helping you. Anaphylaxis is a medical emergency and you should always call 999 for help, even if you have used an adrenaline auto-injector to treat it.
How does it work?
Anaphylaxis, or anaphylactic shock, is a severe and potentially life-threatening reaction to a trigger like an allergy. It happens when the immune system of the body overreacts to a trigger. This overreaction can cause various symptoms such as swelling of the throat, lips and tongue, rash, shortness of breath, vomiting, and nausea. It can also lead to serious problems with the cardiovascular system and blood flow
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. It causes blood vessels to constrict, stimulates heartbeat, relaxes muscles in the lungs to improve breathing and reduces swelling.
Jext dosage
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.
If you’re not sure about the correct dose for you, speak to your GP for advice. Sometimes a single dose of adrenaline may not be sufficient to completely reverse the effects of a serious allergic reaction. This is why you should always carry 2 adrenaline pens. If symptoms have not improved within 5 - 15 minutes of the first injection, you should use a second injection.
Jext alternatives
Adrenaline auto-injectors are critical medicines that can stop allergic reactions from becoming life-threatening. The other available brands of adrenaline auto-injectors are called EpiPen and Emerade. They are prescription-only medicines that can be prescribed by your GP if you are at risk of anaphylaxis.
Each brand of adrenaline auto-injector is used slightly differently, although all of them are designed to be easily injected. Visit the NHS anaphylaxis page for information on how to use each brand, or see the instructions printed on the side of the auto-injector that you have.
