How to use Fasenra Pen pre-filled pen

Print page

If you and your doctor or nurse have decided that you can inject Fasenra (benralizumab) yourself, it is important that you know how to prepare and inject it properly.

This short video shows you how to use Fasenra Pen pre-filled pen (autoinjector).

Ensure you read the ‘Instructions for Use’ carefully before using Fasenra Pen. You should receive training on how to prepare and inject the pre-filled pen. Follow all directions given to you by your doctor or nurse carefully.

Checklist of steps

  1. Gather and set up on a clean, flat surface:
    • Fasenra Pen (which may need to be removed from refrigerator)
    • Alcohol wipe
    • Cotton ball or gauze
    • Sharps disposal container
  2. Allow pen to warm up at room temperature for about 30 minutes (if it has been in refrigerator)
  3. Check liquid through viewing window – it should be clear and colourless to yellow. It may contain small white particles and a small air bubble (do not use if liquid is cloudy, discoloured, or contains large particles)
  4. Choose injection site – this may be front of your thigh or lower part of your abdomen. A caregiver may also inject you in the upper arm (do not try to inject yourself in the arm). For each injection, use a different site at least 3 cm away from where you last injected
  5. Wash your hands with soap and water
  6. Clean injection site with alcohol wipe and let it air dry
  7. Remove cap from pen
  8. Position pen at injection site and place green needle guard flat against skin (90-degree angle). Ensure you can see the viewing window
  9. Press down firmly. A click will tell you the injection has started, and the green plunger will move down in viewing window
  10. Hold down firmly for 15 seconds. A second click will tell you the injection has finished, and the green plunger will fill viewing window
  11. Lift pen straight up
  12. Check viewing window to ensure all the liquid has been injected*
  13. If there is a small amount of blood or liquid at the site, gently apply pressure to the area with a cotton ball or gauze, and apply a Band-Aid if needed
  14. Dispose of used pen in sharps disposal container
  15. Dispose of cap and other used supplies in household rubbish

*If green plunger does not fill viewing window, you may not have received the full dose. Contact your doctor, nurse or pharmacist
