Step 1: How Do I Prepare My Wegovy® Pen?
Before injecting Wegovy®, prepare your pen and supplies carefully.
Remove your Wegovy® pen from the refrigerator.
Place all required items on a clean surface:
Wegovy® pen
Disposable needles
Sharps bin
Check the expiry date on the Wegovy® pen and look for any signs of damage. Do not use Wegovy® if it has expired or appears damaged.
Check that the name and dose on the Wegovy® pen match your prescription.
Wash your hands thoroughly with soap and water.
Remove the pen cap and inspect the liquid inside the Wegovy® pen. The liquid should be clear and colourless. Do not use the Wegovy® pen if the liquid is cloudy, coloured, or contains particles.
How Do I Attach a New Needle to My Wegovy® Pen?
Select a new disposable needle for your Wegovy® injection.
Never reuse a needle.
Do not use a bent or damaged needle.
Check the paper tab and outer needle cap for damage. If either is damaged, dispose of the needle in a sharps bin.
To attach the needle:
Tear off the paper tab.
Push the needle straight onto the Wegovy® pen.
Twist until secure.
Remove the outer needle cap and keep it.
Remove the inner needle cap and dispose of it.
Step 2: How Do I Check the Flow of My Wegovy® Pen?
You only need to check the flow before your first injection with a new Wegovy® pen. This makes sure the Wegovy® pen is working correctly.
To check the flow:
Turn the dose selector until the flow check symbol lines up with the dose pointer.
Hold the Wegovy® pen with the needle pointing upwards.
Press the dose button until the dose counter returns to "0".
Look for a small drop of medication at the needle tip.
If no droplet appears:
Repeat the flow check up to two more times.
If still no droplet, replace the needle and try once more.
If the Wegovy® pen still does not show a droplet, do not use it — MedExpress can help arrange a replacement or further support.
Step 3: Where Can I Inject Wegovy®?
You can inject Wegovy® into:
The upper arms
The stomach (abdomen)
The front of the thighs
The injection site choice is up to you.
Important: Rotate your Wegovy® injection site each week to help reduce skin irritation.
Step 4: How Do I Administer My Wegovy® Injection?
To inject your Wegovy® dose:
Turn the dose selector until it stops and your prescribed dose lines up with the dose pointer.
Position the Wegovy® pen at a 90-degree angle to your skin.
Insert the needle into your skin.
Press and hold the dose button while counting slowly to 6.
Make sure the 0 (zero) icon is visible in the dose window.
Remove the needle from your skin.
If bleeding occurs, gently press the injection site with a clean tissue. Do not rub.
What Should I Do After My Wegovy® Injection?
After completing your Wegovy® injection:
Guide the needle tip into the outer needle cap on a flat surface.
Carefully push the outer needle cap fully on.
Unscrew the used needle.
Dispose of the needle in your sharps bin.
Replace the Wegovy® pen cap.
Store your Wegovy® pen safely in the refrigerator.
Once you have used all 4 doses, you can dispose of the empty Wegovy® pen in your household bin.
