Temperature Safety During Travel
Key storage rules for Mounjaro® when travelling:
Room temperature: A Mounjaro® pen can remain at room temperature (below 30 °C) for up to 30 days.
Warm climates: If temperatures may exceed 30 °C, store Mounjaro® in a refrigerated range of 2 °C to 8 °C using cooling support.
Protection: Keep Mounjaro® in the original packaging, protected from direct heat, sunlight, and light exposure.
Cooling: For warm climates or long journeys, use an insulated cooler bag or medication travel case with a cold pack.
Managing Dosing Across Time Zones
If you are travelling across time zones, you may need to adjust the timing of your weekly injection.
Small time differences: If the time difference is only a few hours, you can generally stick to your usual injection day and time.
Significant time differences: If you are travelling to a destination with a large time difference, you can adjust your injection time to match your new local time.
The 4-Day Rule: Ensure there are at least 4 days (96 hours) between your injections. If your travel schedule would result in your next dose being due in less than 4 days from your last one, wait until you are at your destination to adjust your schedule safely.
If you are unsure how to adjust your specific dosing day, please consult your clinical team before you depart.
Travelling by Plane
When flying with Mounjaro®:
Hand luggage: Always carry Mounjaro® in your hand luggage. Checked luggage can experience extreme temperature and pressure changes that may damage the medication.
Security: Place the Mounjaro® pen and needles in a transparent plastic bag for security screening.
Identification: Keep the original Mounjaro® box with the dispensing label clearly visible to identify the medication.
Sharps: Pack your sharps container in your checked luggage, in line with standard airline safety practices.
Before You Depart
Airline policies: Review your airline’s rules for carrying prescription medication and sharps.
Customs: Check import requirements for your destination country to ensure you have the necessary documentation.
Proof of prescription: Carry a copy of your prescription confirming the medication is for personal use, in case verification is required - MedExpress can provide this if needed
Key Takeaway
Mounjaro® must stay below 30 °C and be protected from heat and light. By carrying your medication in hand luggage and planning your dosing schedule around time zone changes—ensuring a minimum of 4 days between injections—you can travel safely and maintain your treatment progress.
