Why Must I Read the Patient Information Leaflet (PIL) Before My First Dose?
Even if you've 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 MedExpress 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.
What Are the Weekly Handling Requirements for Both Pens?
While the internal mechanisms differ, the weekly handling requirements for Mounjaro® and Wegovy® 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.
How Do I Get Started With My Wegovy® Pen?
To make sure your first dose of your MedExpress Wegovy® pen is successful, follow these steps:
Inspect the Device: Before injecting, always check the pen to make sure 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.
