Can you travel with weight loss injections? Yes, you can travel with prescription weight loss injections such as semaglutide (Wegovy) and liraglutide (Saxenda) within the UK and internationally, provided you follow specific regulations and carry appropriate documentation. These GLP-1 receptor agonist medications are classified as prescription-only medicines (POMs) under MHRA regulation. Successful travel requires proper storage, compliance with airline and airport security protocols, and awareness of destination country requirements. This guide explains UK regulations, storage requirements, documentation needs, and practical strategies for maintaining your treatment schedule whilst travelling domestically or abroad.
Quick Answer: You can travel with weight loss injections such as semaglutide and liraglutide within the UK and internationally, provided you carry them in original packaging with prescription documentation and maintain proper temperature control.
Travelling with prescription weight loss injections such as semaglutide (Wegovy) or liraglutide (Saxenda) is permitted under UK and international regulations, provided you follow specific guidelines. These medications are classified as prescription-only medicines (POMs) in the UK, regulated by the Medicines and Healthcare products Regulatory Agency (MHRA).
When travelling domestically within the UK, you may carry your weight loss injections with you. Keeping them in hand luggage is strongly recommended to maintain proper temperature control and prevent loss. The medication should remain in its original packaging with the pharmacy label clearly visible, displaying your name, prescriber details, and medication information.
For international travel, regulations vary by destination country. Most nations permit travellers to carry personal prescription medications, but some countries have strict controls on injectable medicines or specific drug formulations. It is essential to research your destination's regulations well in advance of travel. The Foreign, Commonwealth & Development Office (FCDO) website provides country-specific guidance, and you should also consult the embassy or consulate of your destination country.
The quantity of medication you can carry is typically limited to what is reasonable for personal use during your trip. Carrying excessive quantities may raise questions at customs and could be interpreted as intent to supply, which is illegal without appropriate licences. Always ensure your prescription is current and that you have supporting documentation from your prescribing healthcare professional.
It's also advisable to check your airline's policies regarding the carriage of medicines, needles and cooling packs before travel, as requirements may vary between carriers.

Start HereProper storage of weight loss injections is critical to maintain their efficacy and safety. GLP-1 receptor agonists like semaglutide and liraglutide are temperature-sensitive biological medications that require refrigeration before first use. According to manufacturer guidelines, unopened pens should be stored between 2°C and 8°C and protected from light.
Once in use, product-specific storage requirements apply. According to the Electronic Medicines Compendium (EMC) SmPCs, Wegovy pens can be kept at room temperature (below 30°C) for up to 6 weeks after first use, Saxenda for 30 days, and both should be protected from light. Never freeze these medications—if frozen, they must be discarded as they will be damaged and ineffective.
When travelling, use a medical-grade cooling case or insulated travel pouch specifically designed for injectable medications. These products often contain gel packs that maintain appropriate temperatures for several hours. Avoid placing medications directly against ice packs, as freezing will permanently damage the medication.
During flights, never pack your weight loss injections in checked luggage, as cargo holds can experience extreme temperature fluctuations that may compromise the medication. Keep your injections in your hand luggage where cabin temperature is controlled. If you're travelling to warm climates, plan to refrigerate your medication upon arrival at your accommodation. Many hotels will accommodate requests to store medication in room minibars or provide access to staff refrigeration facilities.
Inspect your medication regularly during travel. If the solution appears cloudy, discoloured, or contains particles, do not use it. These changes indicate the medication has degraded and may be unsafe or ineffective. When travelling across multiple time zones, maintain your injection schedule based on your home time initially, then gradually adjust to local time to minimise disruption to your treatment regimen and reduce potential side effects.
Consider avoiding starting a new medication or increasing your dose just before long flights, as this may increase the risk of gastrointestinal side effects during travel.
Airport security procedures accommodate passengers travelling with medical injectables, but you must follow specific protocols to ensure smooth passage through checkpoints. In the UK, according to Department for Transport (DfT) guidance, essential medicines, including liquid medications, can exceed the standard 100ml limit when accompanied by supporting documentation.
Present your medications separately from other belongings at security screening, and inform security staff about your medical items. Security personnel may need to inspect the packaging and verify the prescription label matches your identification. The medication must be in its original pharmaceutical packaging—transferring injections to unmarked containers is not permitted and will likely result in confiscation.
For UK departures, the DfT advises that passengers carrying injectable medicines should inform security officers before screening begins. You may be asked to demonstrate that the device is genuine medical equipment, though you will not be required to administer the injection. Some airports have dedicated assistance lanes for passengers with medical needs, which can expedite the process.
Needles and syringes are permitted in hand luggage when accompanied by the corresponding prescription medication. Small travel sharps containers for safe disposal of used needles are also generally allowed, but check with your specific airline as policies may vary. Carry only the quantity needed for your journey, plus a small contingency. Ensure you have sufficient pen needles and alcohol swabs for your trip, as these may not be readily available at your destination.
Allow extra time at security checkpoints, particularly during busy travel periods. If you encounter difficulties or feel your medication is not being handled appropriately, politely request to speak with a supervisor or the airport's medical assistance team. Most major airports have protocols to support passengers with medical conditions and will work to resolve issues whilst maintaining security standards.
Comprehensive documentation is essential when travelling internationally with weight loss injections. At minimum, you should carry a letter from your prescribing doctor or healthcare provider on official letterhead. This letter should include your full name and date of birth, the medication's generic and brand names, dosage and frequency, confirmation that the medication is for personal use, and the duration of your treatment. The letter should be recent, though specific dating requirements vary by destination.
It's important to note that GLP-1 receptor agonists like semaglutide and liraglutide are not classified as controlled drugs in the UK. However, some countries have different classifications or restrictions on importing medicines. The FCDO website provides country-specific guidance, and you should verify requirements at least 4-6 weeks before departure.
Carry copies of your original prescription showing the prescriber's details, including their professional registration number. If you're travelling for an extended period and need to obtain refills abroad, this documentation will be essential. However, be aware that weight loss injections may not be available or may require local prescriptions in some countries, as licensing and availability vary globally.
For certain destinations, particularly in the Middle East and Asia, you may need to contact the embassy in advance to obtain special permits for importing medications. Some countries have strict pharmaceutical import regulations regardless of whether the medication is controlled or not.
Keep all documentation easily accessible during your journey—store copies in both physical and digital formats. Photograph your prescription labels and doctor's letter, and email them to yourself or store them in secure cloud storage. This redundancy ensures you can provide evidence of legitimate medical need even if physical documents are lost during travel.
If travelling to a country where English is not widely spoken, consider having key medical information translated into the local language to facilitate communication with healthcare providers or officials if needed.
Maintaining your injection schedule whilst travelling requires advance planning, particularly when crossing time zones. For weekly semaglutide (Wegovy), you may adjust your injection day by up to 3 days if necessary, but the SmPC specifies there should be at least 2 days between doses. For daily liraglutide (Saxenda), try to maintain as consistent a schedule as possible to optimise therapeutic effects and minimise side effects.
When travelling across multiple time zones, gradually adjust your injection timing rather than making abrupt changes. For daily injections, if you normally inject at 8am UK time and travel to a destination five hours ahead, you might initially inject at your usual time relative to UK, then shift by one hour per day until aligned with local time. This approach helps your body adapt and reduces the risk of gastrointestinal side effects, which are common with GLP-1 medications.
Plan your injection schedule around your travel itinerary. Avoid administering injections immediately before long flights, as side effects such as nausea may be exacerbated by air travel. If you experience significant gastrointestinal symptoms, ensure you have access to appropriate facilities and consider carrying anti-emetic medication as advised by your healthcare provider. Stay well-hydrated during travel, as dehydration can worsen side effects.
Before departure, calculate the exact number of doses required for your trip, plus a small contingency within destination import limits. If you're travelling for longer than your current prescription covers, arrange with your GP for an extended prescription or early refill before departure. NHS prescription regulations typically allow for this when travel is planned in advance.
If you miss a dose whilst travelling, follow the manufacturer's guidance specific to your medication. According to the SmPC, for Wegovy, if fewer than five days have passed since your missed dose, administer it as soon as you remember. If more than five days have passed, skip the missed dose and resume your regular schedule. For Saxenda, take your dose as soon as you remember if it's within 12 hours of your usual time; otherwise, skip it and resume the next day. Never double dose to compensate for a missed injection.
While abroad, if you need medical advice, contact local healthcare services or your travel insurer's medical assistance line. You may also contact your prescribing healthcare provider directly. Seek urgent medical attention if you experience severe or persistent abdominal pain, symptoms of pancreatitis or gallbladder problems, or persistent vomiting/dehydration. If you experience suspected side effects, you can report them through the MHRA Yellow Card scheme upon your return to the UK.
Yes, you can take weight loss injections through UK airport security in hand luggage. Present them separately at screening in original packaging with prescription labels, and inform security staff about your medical items before screening begins.
Store unopened pens at 2–8°C in a medical-grade cooling case. Once in use, Wegovy can be kept below 30°C for up to 6 weeks and Saxenda for 30 days. Never freeze the medication or pack it in checked luggage.
Carry a letter from your prescribing doctor on official letterhead stating your name, medication details, dosage, and confirmation of personal use. Also carry copies of your original prescription and research destination country requirements through the FCDO website or relevant embassy.
