Traveling with chronic diseases like diabetes can be stressful, especially when your treatment depends on refrigerated and temperature-sensitive medications like Mounjaro or insulin.
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:
  1. 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). 
  1. 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.

Fortunately, we’ve got you covered. Keeping medications cool while you're traveling is our job! We’ve designed the most convenient and performant medical-grade travel coolers. Here are our best travel cases for Mounjaro pens:

4AllFamily Travel Cooling Cases for Mounjaro pens

4AllFamily's Nomad Travel Cooler - Fit 1 Mounjaro pen (Medium) or 2 Mounjaro pens (Big)

Keeping medicines refrigerated while traveling isn't such an easy thing. We've been there, and we know about dripping ice coolers, unreliable temperatures, and lost medications.
Our Nomad cooling bottle can keep Mounjaro pens at fridge temperature between 36°F and 46°F (2°C and 8°C) for up to 30 hours with an outside temperature of 104°F / 40°C. It works with biogel freeze packs and doesn’t require electricity, making a small, lightweight cooler, easy to carry around wherever you go. 
If you need to carry higher volumes or refrigerate your pens longer, check out our Voyager and Explorer models. They act like real mini-fridges and offer higher performances when plugged into any USB power source (car cigarette lighter, portable solar panel, power bank, etc.).

More Tips to Keep Mounjaro Cool while Traveling

Besides using a cooler, here are a few pieces of advice and good practices to keep your Mounjaro pens cool and protected from light when outside of your home:
  • Always keep your Mounjaro pens in the shade.
  • Avoid direct sunlight.
  • Use a thermometer to keep track of temperatures.
  • Never leave your injections in the car.
  • Do not place your medicine near a heat source (fireplace, stove, barbecue, hot plate, oven, burner, etc.)
  • Only take your medicine out if you have no other choice.
  • Leave your pens at home if you go to a sunny place like the beach.
  • Keep track of the expiration date, and never use a Mounjaro pen that's been out of the fridge for more than 21 days or exposed to high temperatures even briefly.

Flying with Mounjaro

Many of you are wondering if you can take Mounjaro on a plane. Yes, you can! The Transportation and Security Administration guidelines about traveling with medications are straightforward:
  • Liquid injectable medicines are allowed on the plane. The 3.4 ounces liquid restriction does not apply to medical supplies.
  • You’re allowed to take needles and syringes on the plane when it’s needed for your treatment. 
When flying with Mounjaro, always pack your injector pens in your carry-on bag. Never leave them in the checked luggage, as the hazardous temperature and atmospheric conditions could damage your medicine.
You can download a free TSA medication notification card. It's no obligation, but it may help speed up and smooth the airport security screening process.
When flying to international destinations with medications like Mounjaro, you might be required to show the following documentation:
  • A doctor’s letter
  • Your medical prescriptions
  • A document from your pharmacy
  • The original containers and labels of the medicine
  • Proof of medical insurance 
Inquire with the embassy or local representatives or your destination country before departure.

Dear Heather,
The best is to avoid temperature fluctuations that happen when you take it out of the fridge and then back in again. If your Mounjaro injections have been out of the fridge for 9 hours, it’s best to keep them at fridge temperature. If the temperature outside is too warm, then it’s safer to put it back in the fridge. However, this would not prolong its shelf life. From the moment Mounjaro has reached room temperature, it must be used with 21 days, independently of whether or not it’s been back into the fridge.
I hope this answers your question,
Wishing you a safe and happy trip,
4AllFamily Customer Care Team


If mounjaro is unrefridgerated for 9 hours can it be safely refrigerated again? I know you can leave it out for 21 days unrefrigerated but can it be out of the fridge and then put back in.

I am flying

Thanks so much

Dear Heather,
Most medicines are safe to go through x-ray and metal detector machines at the airport, Wegovy and Mounjaro included. However, if you’re not comfortable with it, you have the right to request a hand check instead, so feel free to do so!
Best regards,
4AllFamily Customer Care Team

Heather said:

Can the Wegovy pen go through the scanner at security or will the lights harm it? I’ve read to hand the medication to TSA & ask them not to put it on the belt. Is that true?

Hi AJ Majumdar,
Thanks for your comment! You’re right, Mounjaro does not need to be refrigerated for up to 21 days. However, according to its manufacturer, it must be protected from high heat and should never be exposed to temperatures above 86°F (30°C). Therefore, people living in or traveling to places where the outside temperature may get above that threshold do need a cooler!
Best regards,

AJ Majumdar said:

Monjauro is fine to not be refrigerated (per their own site) for up to 21 days, so you do NOT need to travel with a cooler unless you are planning to be away from a fridge for more than 21 days.

Hi Ed Feist,
The Big Nomad Cooler is back in stock so you should be able to get it now. Sorry about that, we’re having very high demand before the summer!
We do not recommend removing the pen cap because it is there to protect the medicine from light. Anyway, 3 Mounjaro pens would not fit into the Medium Nomad or the Soft Companion.
Let us know if you need anything else,
Safe travels!

I need to travel with three Mounjaro pens. According to this article I need the “Big” 4AllFamily’s Nomad Travel Cooler. However, the “Big” is out of stock. If I remove the grey top of the Mounjaro pens would three of them fit in the “Medium” 4AllFamily’s Nomad Travel Cooler or maybe in the “Companion Cooling Bag”? Thank you!
