Whether for a day trip, a week holiday, or a year around the globe, planning and packing your medicines and medical supplies must be well thought out to ensure they get to your destination without any issue.
Depending on the length of your trip, your destination (national or international), and your transportation means (airplane, car, boat, train), there are some precautions to take and documents to prepare to travel with Mounjaro injections.

Mounjaro Travel Cases
The temperature is the first and most important thing to consider before traveling with Mounjaro pens.As you know, Tirzepatide, the active ingredient in Mounjaro, is a biological drug that must be refrigerated to stay effective.
According to Eli Lilly, Mounjaro’s manufacturer, your pens can only stay out of the fridge for 21 days, and when they do, they still need to be protected from high heat.
Exposure to temperatures above 86°F (30°C), even briefly, could spoil the medicine inside your pen and make it lose part or all of its potency.
These temperature restrictions imply extra care when traveling with Mounjaro, especially in two kinds of scenarios:
- You’re traveling for more than 21 days. In that case, you must keep your pens constantly refrigerated between 36°F and 46°F (2°C and 8°C).
- You're traveling for less than 21 days, but the outside temperature may get higher than 86°F (30°C). In that case, you must protect your pens from the heat and ensure they stay at room temperature.
