Flying with Wegovy (semaglutide) is permitted on UK and international flights, provided you follow airline policies and security regulations. Wegovy is a GLP-1 receptor agonist approved by the MHRA for chronic weight management in adults with obesity or overweight with weight-related comorbidities. As a prescription-only injectable medicine requiring refrigeration, proper planning is essential to maintain its efficacy during travel. Passengers must carry Wegovy in hand luggage, declare it at security checkpoints, and provide supporting documentation such as a prescription or doctor's letter. Understanding storage requirements, temperature control, and airline-specific protocols will ensure safe transport of your medication whilst complying with UK Civil Aviation Authority and international aviation security standards.
Quick Answer: You can fly with Wegovy by carrying it in hand luggage with proper documentation, maintaining appropriate storage temperatures, and declaring it at airport security checkpoints.
Yes, you can fly with Wegovy (semaglutide). Passengers are permitted to carry prescription medications, including injectable treatments, on flights within the UK and internationally. Wegovy is a glucagon-like peptide-1 (GLP-1) receptor agonist approved by the Medicines and Healthcare products Regulatory Agency (MHRA) for chronic weight management in adults with obesity or overweight with weight-related comorbidities. As a prescription-only medicine requiring refrigeration and careful handling, it is considered a medical necessity for air travel.
Airlines and aviation security authorities recognise that passengers may need to transport temperature-sensitive medications. The UK Civil Aviation Authority (CAA) has established protocols to facilitate the safe carriage of injectable medicines. For international travel, different regulations may apply, such as those of the Transportation Security Administration (TSA) in the United States. Wegovy must be transported in accordance with airline policies and security regulations, which typically require passengers to declare medications at security checkpoints and carry supporting documentation.
It is important to plan ahead when flying with Wegovy. Passengers should contact their airline at least 48–72 hours before departure to inform them of their need to carry injectable medication and any associated equipment, such as needles or cooling packs. Most airlines will provide guidance on their specific requirements and may request advance notification for certain items. Understanding these regulations and preparing appropriate documentation will help ensure a smooth journey whilst maintaining the integrity and efficacy of your medication throughout your travels.
UK airport security regulations permit passengers to carry prescription medications in hand luggage, including injectable treatments like Wegovy. When passing through security at UK airports, you should inform security officers that you are carrying medication and present it for inspection. The Department for Transport (DfT) allows liquid medications exceeding the standard 100ml limit, provided they are accompanied by supporting documentation such as a prescription or doctor's letter, as outlined in the official UK government hand luggage restrictions guidance.
Security officers may request to inspect your Wegovy pens and any accompanying supplies. This inspection is typically visual and does not compromise the sterility of pre-filled pens. You should keep medications in their original packaging with pharmacy labels clearly visible, showing your name, the medication name, and prescribing information. If travelling with cooling packs or gel packs to maintain appropriate storage temperature, these are generally permitted but must be declared at security.
If travelling to or through the United States, be aware that TSA regulations similarly allow medically necessary liquids, gels, and injectables in carry-on baggage. These items should be separated from other belongings and declared to TSA officers at the checkpoint. Having proper documentation significantly expedites the screening process in both UK and international airports.
It is advisable to arrive at the airport with additional time when carrying injectable medications, as security screening may take longer. Most security personnel are familiar with injectable diabetes and weight management medications, but being prepared to explain your medical need and having documentation readily accessible will facilitate a more efficient screening process. If you have concerns about specific security procedures, contact your departure airport's customer service team in advance for guidance.

Start HereProper packing and storage of Wegovy during air travel is essential to maintain its efficacy. According to the Wegovy Summary of Product Characteristics (SmPC), Wegovy must be stored between 2°C and 8°C (refrigerated) until first use, after which it may be kept at room temperature (up to 30°C) for up to 28 days. When planning air travel, consider your journey duration and whether you will have access to refrigeration at your destination.
For flights lasting several hours, Wegovy pens can be safely transported at room temperature provided they remain below 30°C and are used within the 28-day window from first removal from refrigeration. Keep your medication in an insulated medication travel case or cooling pouch designed for injectable medications. These specialised cases often include reusable cooling elements that maintain appropriate temperatures without freezing the medication. Never allow Wegovy to freeze, as this permanently damages the medication and renders it ineffective. Any pens exposed to temperatures above 30°C or to freezing conditions should be discarded.
When packing, place Wegovy pens in their original carton with the patient information leaflet. This packaging provides some insulation and clearly identifies the medication. Position the medication case in an easily accessible part of your hand luggage, as you may need to remove it during security screening. Avoid placing Wegovy in checked baggage, where temperatures in the aircraft hold can fluctuate significantly and potentially expose the medication to freezing conditions.
Consider packing additional supplies including alcohol wipes, a sharps container for used needles, and backup cooling packs. If travelling to warm climates, research local pharmacy options for purchasing additional cooling supplies if needed. Some patients find it helpful to pack a small thermometer to monitor storage conditions, particularly during extended layovers or delays. Always carry more medication than you anticipate needing to account for potential travel disruptions.
Wegovy should always be carried in hand luggage rather than checked hold baggage. This recommendation aligns with NHS advice on travelling with medicines and aviation medicine guidance for several important reasons. Firstly, temperatures in aircraft cargo holds can fluctuate significantly during flight, potentially dropping below freezing at cruising altitude, which could cause irreversible damage to the medication. Wegovy contains a protein-based active ingredient that is permanently denatured by freezing, rendering it ineffective even if subsequently thawed.
Carrying Wegovy in the cabin allows you to maintain control over storage conditions and ensures the medication remains within the acceptable temperature range. Cabin temperatures are regulated for passenger comfort, typically between 18°C and 24°C, which falls within the acceptable range for Wegovy that has been removed from refrigeration. Additionally, having your medication in hand luggage means it remains accessible should you need to administer a dose during a long-haul flight or extended layover.
There is also a practical consideration regarding lost luggage. Checked baggage can be delayed, misdirected, or lost, which would leave you without essential medication at your destination. Prescription medications, particularly those requiring specific storage conditions, should never be placed at risk of separation from the passenger. If your checked luggage is delayed, obtaining replacement Wegovy abroad may be difficult, expensive, or impossible depending on local prescribing regulations and medication availability.
Airlines and aviation authorities advise passengers to carry prescription medications in hand luggage. There are no restrictions on the quantity of medication you can carry for personal use during your trip, provided you have appropriate documentation. When booking flights, inform the airline of your need to carry injectable medication, and request any specific guidance they may have regarding medical equipment and supplies in the cabin.
Comprehensive documentation is essential when flying with Wegovy. At minimum, you should carry a current prescription or repeat prescription slip showing your name, the medication name (semaglutide/Wegovy), dosage, and prescribing clinician's details. This prescription should be recent and clearly indicate that the medication is for your personal use. Many healthcare providers will issue a specific travel letter upon request, which can provide additional detail about your treatment.
A doctor's letter or medical certificate can be invaluable during air travel. This document should be printed on official letterhead and include: your full name and date of birth; diagnosis or medical condition being treated; medication name (both brand name Wegovy and generic name semaglutide); dosage and frequency; confirmation that you require this medication during travel; a list of any associated supplies (needles, sharps container, cooling packs); and the prescriber's contact information and signature. Request this letter at least two weeks before your departure to allow time for your GP or prescribing clinician to prepare it.
For international travel, additional documentation may be required. Some countries have specific regulations regarding the importation of prescription medications, particularly controlled substances or injectables. Whilst Wegovy is not a controlled drug, it is advisable to check the destination country's customs and border protection requirements. The UK Foreign, Commonwealth & Development Office (FCDO) website provides country-specific guidance on travelling with medicines, and you may also contact the embassy or consulate of your destination country for clarification.
Keep all documentation easily accessible in your hand luggage, preferably in a clear plastic wallet with your medication. Carry both physical copies and digital backups (photographs or scans on your mobile device) in case documents are misplaced. If travelling with multiple weeks' supply of medication, ensure your prescription or doctor's letter specifies the quantity you are carrying to avoid questions at customs about commercial importation.
Long-haul flights present unique challenges for managing Wegovy, but with proper planning, you can maintain your treatment schedule effectively. According to the Wegovy SmPC, if you miss a dose and the next scheduled dose is more than 5 days away, you should take the missed dose as soon as possible. If more than 5 days have passed, skip the missed dose and take the next dose on the regularly scheduled day. You can also change the day of your weekly administration if necessary, as long as the time between two doses is at least 3 days.
Consider your destination time zone when planning injections. If travelling eastward across multiple time zones, you may wish to administer your dose before departure. For westward travel, you might delay your injection until arrival. The key is maintaining the appropriate interval between doses. If you are uncertain about timing, consult your prescribing clinician or pharmacist before travel.
During the flight, store your Wegovy in the overhead locker or under the seat in front of you within an insulated case. Avoid placing it in seat-back pockets where it might be forgotten or exposed to excessive warmth from cabin lighting. If you need to administer an injection during the flight, use the aircraft lavatory for privacy and proper disposal of the needle in your portable sharps container. Inform cabin crew if you require assistance or have any concerns about medication storage during the flight.
Stay well-hydrated during long-haul flights, as dehydration can exacerbate some of Wegovy's gastrointestinal side effects. The low humidity in aircraft cabins can intensify feelings of nausea or discomfort. Avoid excessive alcohol consumption and heavy meals, which may worsen these effects. If you experience significant nausea or vomiting during travel, consider carrying anti-emetic medication prescribed by your doctor. Seek medical advice if vomiting persists for more than 24 hours. Upon arrival at your destination, store Wegovy in a refrigerator as soon as possible if you have not yet exceeded the 28-day room temperature storage period, or continue room temperature storage if already initiated, ensuring temperatures remain below 30°C.
If you experience any suspected side effects from Wegovy during or after travel, report them to the MHRA Yellow Card Scheme, which monitors the safety of medicines in the UK.
Whilst not always mandatory, a doctor's letter on official letterhead is highly recommended when flying with Wegovy. The letter should include your name, diagnosis, medication details (semaglutide/Wegovy), dosage, and confirmation that you require the medication during travel, along with the prescriber's signature and contact information.
Yes, Wegovy can safely pass through airport security scanners. Inform security officers that you are carrying injectable medication and present it for visual inspection. Keep Wegovy in its original packaging with pharmacy labels clearly visible to expedite the screening process.
If Wegovy freezes, it is permanently damaged and must be discarded, as freezing denatures the protein-based active ingredient and renders it ineffective. This is why you must always carry Wegovy in hand luggage rather than checked baggage, where cargo hold temperatures can drop below freezing.
