My adrenaline auto injector (Jext): what to do and how to use it

What to do and how to use it

This leaflet must accompany the BSACI Jext treatment plan

If you are experiencing any of the severe reactions on your treatment plan, and there is a need for the Jext auto injector, follow these simple instructions:

  1. Lay your child down on the floor. If breathing is difficult allow your child to sit.
  2. Administer the Jext auto injector into the outer thigh as demonstrated, and hold in place for 10 seconds.
  3. If possible elevate their legs on a cushion or pillow (this helps with the blood flow around the body).
  4. Dial 999 and ask for an ambulance, telling the operator Anaphylaxis (ANA-FIL-AX-IS)
  5. Stay with your child until the ambulance arrives.
  6. Do not stand your child up. Keep your child lying flat, even if they feel better. If your child vomits or feels sick, place them on their side, in the recovery position.
  7. If no improvement after 5 minutes or if the Jext has not activated, give a second Jext device.
  8. Wait for the ambulance to arrive and tell them you have used your Jext auto injector.
