Emergency Treatment for Severe Allergic Reactions (Anaphylaxis)

Jext is a single-use, pre-filled adrenaline auto-injector designed for the immediate emergency treatment of anaphylaxis. Anaphylaxis is a severe, systemic allergic reaction that can be triggered by food, medicines, insect stings, or other allergens. Jext works by rapidly delivering adrenaline to help reverse life-threatening symptoms such as airway swelling and low blood pressure.

Dosage Strengths

• Jext 150mcg: Generally prescribed for children weighing between 15kg and 30kg.

• Jext 300mcg: Generally prescribed for adults and children weighing over 30kg.

How to Use (The "Blue to the Sky, Orange to the Thigh" Rule)

1. Prepare: Grasp the Jext pen in your dominant hand. Remove the yellow cap.

2. Position: Place the black tip against the outer mid-thigh. (Can be applied through clothing).

3. Activate: Push the pen firmly until you hear or feel a "click." Hold in place for 10 seconds.

4. Aftercare: Remove the pen and gently massage the injection site for 10 seconds.

5. Emergency Call: Immediately dial 999 and state "ANAPHYLAXIS." Stay lying down with legs raised until help arrives.

  Critical Safety Information

• Carry Two: Patients at risk of anaphylaxis must always carry two auto-injectors. A second dose may be required if symptoms do not improve within 5–15 minutes.

• Medical Emergency: Jext is a first-aid measure only. Every patient who receives an adrenaline injection must be transported to a hospital by ambulance for monitoring.

• Injection Site: Inject only into the outer mid-thigh. Avoid injecting into the buttocks, hands, or feet.

• Sodium Metabisulfite: Contains sodium metabisulfite, which can rarely cause allergic-type reactions or breathing difficulties in sensitive individuals. However, in an emergency, the benefits of adrenaline outweigh this risk.

Possible Side Effects

Following an injection, the body reacts rapidly to the adrenaline. Expected and temporary effects include:

• Rapid or irregular heartbeat (palpitations).

• Trembling or shaking.

• Coldness or paleness of the skin.

• Nausea and sweating.

• Action: These are normal responses to adrenaline and should subside as the medication is processed.

Composition & Storage

• Active Ingredient: Adrenaline (Epinephrine).

• Storage: Store at room temperature (15°C to 25°C). Do not refrigerate or freeze.

• Inspection: Check the viewing window regularly. The solution must be clear. If it is discoloured, cloudy, or has passed its expiry date, replace the pen immediately.
