How to Travel with Mounjaro: Flights, Road Trips, and Storage Made Simple

Temperature rule when traveling with Mounjaro

Mounjaro comes in a single-use injection pen. Like many injectable medications, the pen and the drug itself are sensitive to heat and freezing.

General storage basics to keep in mind when you travel with Mounjaro include:

• The drug is best stored in a refrigerator before use at 2°C to 8°C (36°F to 46°F).
• Mounjaro can stay at room temperature, up to 30°C (86°F), for a limited time (check your prescribing information label for exact timing).
• Never freeze Mounjaro.
• Don’t leave the drug in direct sunlight or other direct heat sources.

Extreme heat or freezing can damage the drug, reducing its effectiveness and safety.

Flying with Mounjaro

Here are some tips for air travel if you are taking Mounjaro.

Keep it in your carry-on

Never put Mounjaro in your checked luggage, as it will be exposed to extreme temperatures (hot and cold), which can ruin the medication.

Insulate it

For longer flights, it may be a good idea to use insulation around the Mounjaro pen. You can use:

• a small insulated medical pouch
• a frozen gel pack
• a temperature-controlled travel case

Airport security

The Transportation Security Administration (TSA) allows prescription medications, including injectable drugs, in carry-on bags and personal items.

No standard liquid limits apply to prescription medications.

You do not need to:

• put Mounjaro in a travel liquid bag
• discard it or leave it behind due to size limits
• avoid airport X-rays, as standard screening doesn’t damage Mounjaro

What can make the security screening easier if you travel with Mounjaro?

• Keep the drug in the original packaging.
• Carry your Mounjaro prescription with you (or a clear picture of it).
• Let the security officer know you are traveling with prescription injectable medication.

Road trips with Mounjaro

Traveling with Mounjaro by car or train may need additional steps to keep the medication safe.

• Never leave Mounjaro in a parked car: Even a few minutes in a hot car can ruin the medication.
• Keep it insulated: Use a lunch-sized insulated bag with a cool pack, and wrap the pen in a towel or cloth to prevent it from freezing.
• Keep Mounjaro out of direct sunlight: Even if the drug is in your bag or the weather is cold, avoid exposing it to direct sunlight (or to a heater).

Cruise, train, and bus travel with Mounjaro

The same rules apply. Keep Mounjaro with you, in an insulated bag, and avoid freezing it or exposing it to direct sunlight or heat.

For extended cruises, it’s a good idea to confirm your room has a refrigerator. For train travel, you may be able to keep a small cooler in your cabin or store Mounjaro in a nearby staff refrigerator.

Traveling across time zones with Mounjaro

You need to inject Mounjaro once every week around the same time each time. If you’re changing time zones:

• Continue using Mounjaro on the same calendar day each week.
• You can change the time by a few hours (earlier or later, whichever is more convenient for you).
• If you miss a dose, you can inject it up to 4 days after the missed dose. If it’s been more than 4 days, wait until your next regular date and do not double the dose.

For example, if you typically use Mounjaro on Mondays at 10 p.m., and your travel destination is now 5 hours ahead, you can continue taking Mounjaro on Mondays at 10 p.m. local time. If you missed this dose, you can inject Mounjaro any day until late Thursday. If you don’t, wait until the following Monday.

If unsure about the timing or dosing schedule for Mounjaro, it’s a good idea to talk with a doctor before traveling.

Long-term or multi-city travel with Mounjaro

You will need extra planning if you are traveling for over a month or have multiple stops.

• Mounjaro refills can be difficult to obtain, so it’s important to have enough for your entire stay.
• Ensure your prescription is current and doesn’t expire soon.
• Plan refrigeration for the whole stay and all the stops. Mini-fridges sometimes freeze items placed behind the back, so it’s important to test the temperature before leaving your medication there for a whole week.
• Have a backup cooling plan if you’re staying in remote areas or need to spend hours at airports or stations.

International travel with Mounjaro

Each country has its own medication regulations. Before traveling to foreign lands:

• Ensure you know and understand the destination’s rules.
• Confirm injectable medications like Mounjaro are permitted through customs, and ask whether you need additional documentation, including a doctor’s letter.
• Carry your original prescription label with you, and keep your doctor’s contact information at hand, including email addresses and website.
• Keep Mounjaro in the original packaging.

If you plan to stay abroad for a long time or if you’re relocating, check:

• whether Mounjaro is available locally and what you need to do to get a refill
• if there are limits to how many personal refills you bring
• if a new prescription is needed, should you need more Mounjaro

What to do if Mounjaro gets too hot or cold

If your pen froze or was left in extreme heat, do not use it. If in doubt, you can contact your healthcare professional or pharmacist at home.

It’s better to discard your Mounjaro pen than use damaged medication.

Takeaway

Traveling with Mounjaro is manageable with a little planning. Remember to keep the medication with you, protect it from heat, sunlight, and freezing, and plan ahead for long trips that may require refills.
