Preparing Your Wegovy FlexTouch Pen
Check the Pen
Verify the label shows your prescribed dose (0.25mg, 0.5mg, 1mg, 1.7mg or 2.4mg). Inspect through the pen window - solution should be clear and colourless. Do not use if cloudy or contains particles.
Gather Supplies
You'll need:
- Wegovy FlexTouch pen (contains 4 doses)
- NovoFine Plus needle (32G, 4mm - included)
- Alcohol swab
- Sharps bin
Attach the Needle
- Remove pen cap and check paper tab on needle is intact
- Tear off paper tab and push needle straight onto pen
- Turn clockwise until tight (do not overtighten)
Remove Needle Caps
- Pull off outer needle cap and save for disposal later
- Pull off inner needle cap and discard
- A small drop may appear - this is normal
Administering Your Wegovy Injection
Abdomen
At least 5cm from navel
Thigh
Upper outer area
Upper Arm
Back of upper arm
Select Your Dose
Turn dose selector until dose counter shows your prescribed dose. The dashed line must align with dose pointer. You'll hear clicks - don't count these.
Clean Injection Site
Wash hands, then clean skin with alcohol swab using circular motions. Let air dry completely before injecting.
Inject the Dose
- Pinch skin fold (unless using 4mm needle in fatty area)
- Insert needle at 90° angle (45° if very lean)
- Press and hold dose button until counter shows "0"
- Keep holding and slowly count to 6
- Remove needle and dispose safely
Pro Tip: If no drop appeared during priming or dose didn't fully deliver, you may have used a blocked needle. Change needle and repeat.

Frequently Asked Questions
What if I see blood after injecting?

Why does my pen sometimes leak after injection?
This happens if you remove needle too quickly. Always count to 6 while holding dose button, then wait 2 seconds before withdrawing.
How do I know when my pen is empty?
The dose counter won't turn to your full dose (e.g., stops at 1.5mg when trying to select 2.4mg). Each pen contains exactly 4 doses.
