How to pack Wegovy for travel without losing a dose

The night before you leave: your pens are still in the fridge

Picture it: suitcase open on the bedroom floor, toiletries bag sorted, and the Wegovy pens still sitting in the fridge door next to the butter. That's fine, that's exactly where they should be right up until you pack your hand luggage in the morning. What matters is what happens next.

Wegovy pens must be kept at 2–8°C. Once a pen comes out of the fridge, the clock starts on a room-temperature window. The exact duration of that window is printed in your Patient Information Leaflet, and the Wegovy SmPC on the eMC is the authoritative reference if you want the clinical detail. Never guess at the number, it matters. A pen that has exceeded its out-of-fridge window must be discarded, not used.

For journeys of more than a couple of hours, a proper insulin travel cooler (the kind with a documented thermal rating, not a picnic bag) will keep your pen in the safe zone. Pack it in your hand luggage. The hold of an aircraft is not temperature-controlled and can drop below freezing, a frozen pen is also a ruined pen. If you're travelling over a long weekend or the trip spans your injection day, think about timing: some people order their next supply before they go, especially if there's a Monday dispatch cut-off involved.

Getting through airport security with a Wegovy pen

Wegovy pens are medical devices. UK and most international airports allow them through security in hand luggage, but the process goes more smoothly when you're prepared. Carry your prescription, a letter from your pharmacist or prescriber, or both. Declare the pens at the security lane rather than burying them in a washbag. Officers are used to insulin pens and similar devices; a confident, upfront explanation rarely causes delays.

Liquid rules: the 100ml rule applies to liquids, gels and aerosols, pre-filled injection pens are medical devices and are generally exempt, but policies vary by airline and country, so check with your carrier before travel. Our guide to air travel with Wegovy covers what to expect at the security lane and which airline policies are worth checking in advance. The NHS semaglutide medicines page advises carrying your prescription when travelling, which is the simplest single piece of advice to follow.

Needles are sharps. They go through security attached to the pen or separately in a clearly labelled medical sharps wallet. Used needles after injection should go straight into a portable sharps container, hotels and holiday apartments rarely have clinical waste disposal, and leaving used needles loose in a bag is both unsafe and not permitted on most flights. Swap needles for each injection using fresh pen needles to maintain sterility; wipe the injection site beforehand with an alcohol swab.

At your destination: finding a fridge and rotating injection sites

Most hotel rooms have a minibar or in-room fridge. Ask at check-in whether you can store medication there, or request a medical-grade fridge through the hotel's health and wellness team. Airbnb hosts are generally accommodating if you message ahead. The goal is simple: pen back in the fridge as soon as you arrive, within its allowed room-temperature window.

If your injection day falls during the trip, rotate your injection site as you would at home: abdomen, outer thigh, or upper arm, each in a slightly different spot from last time. Wipe the skin first. For the detail on pen use and rotation, refer to your Patient Information Leaflet rather than relying on memory, it's there for exactly this situation.

If you're moving between time zones and unsure whether to shift the injection day or keep it fixed, that's a question for your prescriber before you travel, not a decision to make in the airport. Our clinical team is available to advise. More detail on managing semaglutide on the move is covered in our guide to travelling with Wegovy.

What to do if something goes wrong mid-trip

Pen left out too long. Fridge failed. Pen dropped and the mechanism feels off. These things happen. The answer in each case is the same: do not inject from a pen you're uncertain about. A missed dose is far less risky than injecting from a compromised pen.

Contact your prescriber or pharmacist as soon as you can. If you're in the UK still, reach our aftercare team seven days a week. Abroad, the hotel's on-call doctor or local pharmacy can advise on whether the pen is likely still viable.

Wegovy is covered in detail on our Wegovy treatment page, including how to get started if you haven't begun treatment yet. If you're weighing up whether Wegovy is the right option for your circumstances, a free consultation with a named prescriber is the place to start, they review your case the same day, with no algorithm standing in between. Before your trip, it's also worth reading our practical overview of travelling with Wegovy, which covers packing, storage and what to do if plans change, alongside our step-by-step guide to travelling with semaglutide for anyone who wants the full picture across all semaglutide formats. You can also find context on what a private prescription typically costs at our Wegovy price comparison page if that's useful before you begin.
