Yes. Both Mounjaro® and Wegovy® are supplied in pre-filled, ready-to-use injection pens that follow a very similar administration process. If you are already accustomed to using the Mounjaro® KwikPen®, you will find the transition to the Wegovy® device straightforward.
Use this guide to understand:
Shared features and weekly handling requirements.
Why you must read the specific instructions for your new pen.
How to ensure every injection is performed safely.
CRITICAL: You must read the Patient Information Leaflet
Even if you have been using an injectable medication for a long time, every device has unique mechanical differences. You must read the specific Patient Information Leaflet (PIL) included in your Wegovy® packaging before your first dose.
Manufacturer Guidance: The leaflet contains the only officially approved instructions for the FlexTouch® device.
Priming and Dialling: The way you "prime" the needle and dial your dose may differ slightly from your previous pen.
Safety Checks: The leaflet explains how to verify that your pen is working correctly and what to do if you encounter a mechanical error.
Weekly handling requirements
While the internal mechanisms differ, the weekly handling requirements for both medications are almost identical:
Storage: Both pens must be stored in the refrigerator (between 2°C and 8°C) to maintain the stability of the medication.
Ready-to-use: Both are pre-filled devices; you do not need to manually draw medication from a separate vial.
Sterile Needles: You must use a fresh, sterile needle for every weekly injection to prevent infection and needle blockages.
Weekly Schedule: Both treatments are designed to be administered exactly once every seven days.
Getting started with Wegovy®
To ensure your first transition dose is successful, follow these essential steps:
Inspect the Device: Before injecting, always check the pen to ensure the liquid is clear and colourless. If it appears cloudy or the pen looks damaged, do not use it.
Check the Expiry: Confirm the medication is still within its "Use By" date.

Key Takeaway
The transition to Wegovy® is mechanically very similar to Mounjaro®, but "similar" is not the same as "identical." To ensure you receive your full dose safely, you must follow the specific instructions highlighted in the manufacturer’s leaflet for your new pen.
