In most cases, yes. You can take Mounjaro, Wegovy or Ozempic with you when you travel. Rules for carrying prescription medication vary by destination and airline, so we recommend checking them before you travel. The UK’s National Travel Health Network and Centre advises carrying medication in your hand luggage, in its original labelled packaging, with a copy of your prescription. Temperature limits and the time a pen can stay unrefrigerated depend on the medication and pen type.
- The UK’s National Travel Health Network and Centre (NaTHNaC) advises carrying medication in hand luggage, correctly labelled and in its original pharmacy packaging.
- NaTHNaC also advises carrying a copy of your prescription and a letter from your prescriber listing each medication by its generic name.
- Storage rules vary by brand and device, and by whether a pen is unopened or in use, so we recommend following the leaflet supplied with your own pen.
- The prescribing information for Mounjaro allows a missed dose within 4 days, while the Ozempic label allows 5 days and the Wegovy label applies a 2-day rule.
- To move a dose day for a trip, the Mounjaro label requires at least 72 hours between two doses, and the Ozempic label at least 48 hours.
- The UAE Embassy’s guidance requires returning travellers to carry a prescription for the full quantity of medication they bring in.
Can you fly with Mounjaro, Wegovy or Ozempic?
You can take Mounjaro, Wegovy or Ozempic on a flight. The National Travel Health Network and Centre (NaTHNaC), the UK’s travel health service, advises carrying medication in your hand luggage. It also advises keeping medication correctly labelled and in its original pharmacy packaging.
We recommend keeping your pens out of checked luggage. Temperatures in the hold can vary. A delayed or lost bag could also leave you without your next dose.
NaTHNaC advises contacting the airline before you fly if you carry injectable medication.
Documents to carry with your medication
A copy of your prescription and a covering letter from your doctor can help at border checks and if you need medical care abroad. NaTHNaC advises that the letter lists each medication by its generic name. For injectable medication, it recommends a letter on the prescriber’s letterhead.
Mounjaro contains tirzepatide, Wegovy and Ozempic contain semaglutide, and Foundayo contains orforglipron. Your endocrinologist can provide a letter for your trip if you need one.
NaTHNaC advises checking the status of a medication with the embassy or consulate of each country you visit before you travel.
When you fly back to the UAE, the Embassy of the UAE requires travellers to carry a prescription covering the quantity of medication they bring into the country.
Keeping your pen cool while you travel
Keep unopened pens refrigerated at 2–8°C. Temperature limits and the time a pen can stay unrefrigerated depend on the medication and pen type. Storage also differs between unopened and in-use pens, so we recommend following the leaflet supplied with your own pen.
Our guide to how long a weight loss pen can stay out of the fridge gives the temperature limit and the number of days for each pen, and how to keep a pen cool on a travel day.
Dose days, time zones and missed doses
Mounjaro, Wegovy and Ozempic are weekly injections, and Foundayo is a daily tablet. All four are GLP-1 medications, and Ozempic is approved for type 2 diabetes.
| Medication | If a dose is missed | Source |
|---|---|---|
| Mounjaro (tirzepatide), weekly | Take it as soon as possible within 4 days (96 hours). After 4 days, skip it and take the next dose on the usual day | FDA prescribing information, January 2026 |
| Wegovy (semaglutide), weekly | If the next dose is more than 2 days away, take it as soon as possible. If it is less than 2 days away, skip it | FDA prescribing information, February 2026 |
| Ozempic (semaglutide), weekly | Take it as soon as possible within 5 days. After 5 days, skip it and take the next dose on the usual day | FDA prescribing information, January 2025 |
| Foundayo (orforglipron), daily | Take it as soon as possible, but never take two doses on the same day | FDA prescribing information, July 2026 |
The prescribing information for Mounjaro allows the weekly dose at any time of day, and the Wegovy label and the Ozempic label do the same. A dose day can be moved, provided the gap between two doses is at least 3 days (72 hours) for Mounjaro and at least 2 days (48 hours) for Ozempic.
The Wegovy label allows the time of day to change without a dose adjustment, but sets no rule for moving the day itself. If two or more Wegovy doses in a row are missed, the label allows dosing to resume as scheduled or, if needed, a restart of the dose escalation, as your endocrinologist advises.
Our Mounjaro dosage guide explains the dose steps.
Side effects while you are away
Side effects such as nausea or constipation can be particularly pronounced in the first few days at a new dose. They often improve as your body adjusts, although some symptoms last longer. If a dose increase is due shortly before a long trip, your endocrinologist can discuss its timing.
If you experience nausea or constipation, your endocrinologist can adjust the pace of dose increases and, where needed, prescribe medication to help manage these side effects.
Vomiting or diarrhoea can lead to dehydration, particularly in hot weather. The Mounjaro label links most of its reported cases of acute kidney injury to dehydration after gastrointestinal side effects. We recommend drinking enough fluids, and seeking medical advice immediately if you cannot keep fluids down.
The Medicines and Healthcare products Regulatory Agency (MHRA) advises urgent medical help for severe stomach pain that spreads to the back and does not go away. Our guide to the side effects of Mounjaro lists the other symptoms that need prompt medical advice.
Trips longer than your medication supply
NaTHNaC advises packing enough medication to last the whole trip, with an allowance for delays. If you will be away for longer than your current supply, we recommend speaking to your endocrinologist well before you leave.
Monthly follow-up appointments can be held in person at the clinic or online.
NaTHNaC also notes that falsified medication is more common in some regions. It advises obtaining the medication you need before you travel wherever possible.
Frequently asked questions
Can I skip a week of Mounjaro while I am on holiday?
We recommend continuing your usual weekly dose while you are away. If you miss a dose, the Mounjaro label allows you to take it within 4 days, or to skip it after that and take the next dose on your usual day. If you are considering a longer break, speak to your endocrinologist before you travel.
Do I need to declare Mounjaro on my travel insurance?
Each travel insurer sets its own rules on which medical conditions and medications must be declared. We recommend checking with your insurer before you travel, as an undeclared condition may affect a claim.
How do I take Foundayo when I travel?
Foundayo is a once-daily tablet, taken with or without food. Eli Lilly, the manufacturer, states that it can be taken at any time of day. If you miss Foundayo for 7 or more days in a row, the prescribing information for Foundayo advises contacting your doctor about how to restart. Our Foundayo dosage guide sets out the dose steps.
What should I do if I lose my pen while abroad?
Contact the clinic as soon as possible for advice on your next dose. We recommend not buying a replacement from an unverified seller, because the product may be falsified or stored incorrectly. Our article on the risks of buying Mounjaro online explains how to recognise an unsafe source.
Patients should not decide by themselves to start a GLP-1 medication. A doctor’s review is critical to ensure the treatment is safe and appropriate for the individual.
At our Dubai clinic, your endocrinologist will assess you, review your treatment and help you plan your doses around your trip. You can book a weight loss consultation on +971 4 285 3885 or send us a message on WhatsApp.
