Travelling with severe allergies adds an extra layer of planning, especially when your child relies on an EpiPen. Whether you are flying for a family holiday, a cruise, or a long-haul adventure, knowing how to safely travel with adrenaline auto-injectors can make the journey much less stressful.
The good news is yes – you can absolutely fly with EpiPens. But there are some important things you should do before you get to the airport.
This guide covers everything you need to know about flying with EpiPens, including airport security, airline policies, doctor’s letters, carrying medication abroad, and practical tips that make travelling easier.
Quick Wins Before You Fly With EpiPens
- Always carry EpiPens in hand luggage, never checked baggage
- Take at least two EpiPens per person
- Bring a doctor’s letter or prescription copy
- Check expiry dates before travel
- Pack safe snacks for flights and delays
- Wipe tray tables and armrests if allergens are a concern
- Inform the airline in advance if your allergy is severe
- Know how to access emergency help during the flight
Can You Take EpiPens on a Plane?
Yes – EpiPens are allowed in your hand luggage and should always travel with you in the cabin.
Do not place them in checked luggage.
Checked baggage can be delayed, lost, exposed to extreme temperatures, or inaccessible during the flight. If an allergic reaction happens mid-flight, you need immediate access.
Most airlines and airport security staff are very familiar with EpiPens, especially for children.
Do You Need a Doctor’s Letter?
Technically, many airlines do not require one for standard EpiPens, but I strongly recommend carrying one anyway.
A doctor’s letter can help with:
- Airport security questions
- Customs checks abroad
- Carrying liquid medication alongside the EpiPen
- Prescription-only medications travelling with you
- Controlled medications if your child also takes ADHD medication or other restricted medicines
Your letter should ideally include:
- Full name of the traveller
- Date of birth
- Medical condition (for example severe nut allergy or anaphylaxis risk)
- Medication name (EpiPen, Jext, Emerade if relevant)
- Dosage and prescription details
- Confirmation the medication must stay in hand luggage
- GP or consultant contact details
Some countries are stricter than others, especially in Asia and the Middle East, so paperwork matters. My guide to what to include in a doctors travel letter explains which countries accept a standard letter and which require a bit more information and detail before they approve you to travel with your medication.
How Many EpiPens Should You Travel With?
Most allergy specialists recommend carrying at least two EpiPens per person.
As a Brit, we can only get a prescription for two EpiPens in most circumstances. I do know that some people like to travel with more if they are going on a longer trip.
Delays happen. Lost bags happen. Unexpected reactions happen.
For cruises, remote destinations, or countries where replacing an EpiPen would be difficult, I would usually travel with extra backup pens.
Some families travel with three or four depending on destination and access to healthcare.
Going Through Airport Security
EpiPens can go through airport security without problems.
Keep them:
- In original packaging if possible
- With the prescription label if available
- Easy to access in your cabin bag
- Together with your doctor’s letter
You do not usually need to place EpiPens in the liquids bag because they are medically necessary items, but security staff may want to inspect them.
If travelling with liquid antihistamines, liquid medications, or specialist allergy-safe foods, tell security staff before screening. In some countries, you need a smaller bottle of antihistamine if it was not prescribed by a doctor and doesn’t have the pharmacy label on it or a doctors letter. This applies to countries which still have a limit of 100ml for liquids coming through security. Otherwise, you can bring the larger bottle of antihistamine.
Airport special assistance can also help reduce stress if your child struggles with queues or sensory overload. My guide to getting help at the airport explains all of this and how to book it.
Should You Tell The Airline?
Yes – especially for severe airborne allergies or previous anaphylaxis.
Some airlines can:
- Note the allergy on your booking
- Avoid serving specific allergens nearby
- Allow early boarding for cleaning your seating area
- Offer guidance on onboard food policies
Policies vary a lot between airlines.
Some will make announcements, some will not, and some cannot guarantee allergen-free cabins.
Never rely on the airline alone for safety.
Always bring your own safe food and emergency medication.
What About Airline Food?
Assume nothing.
Even if you pre-order meals, airline catering can change and cross-contamination is always possible. To learn more about the different meal codes assigned to airplane food and what they mean, my guide to airline meal codes is exactly what you need to read.
We always travel with:
- Safe snacks
- Familiar foods
- Backup meals for delays
- Allergy-safe wipes
- Water bottles purchased after security
- Antihistamines and EpiPens
This is especially important for autistic children who may already have a restricted diet alongside allergies.
Sometimes the safest option is simply not using airline food at all.
Keeping EpiPens at The Right Temperature
EpiPens should be stored below 25°C and protected from extreme heat or freezing.
That means:
- Do not leave them in direct sunlight
- Do not store them in a hot car
- Do not put them in the aircraft hold
- Be careful with beach holidays and hot destinations
Some families use insulated medication pouches when travelling to hot countries.
Just avoid freezing packs touching the pen directly.
Hotel and Destination Planning
Think beyond the flight.
Check:
- Nearest hospital or pharmacy
- Local emergency numbers
- Availability of replacement EpiPens abroad
- Translation cards for allergies if travelling internationally
- Restaurant allergy awareness at your destination
For countries where language barriers are significant, allergy translation cards are incredibly helpful. My guide to learning key phrases before you travel includes a link to Lonely Planet’s free eBook with accessible travel translations in 35 languages – each language includes a section about allergies. I also have a guide with a bunch of free allergy translation cards you can download and print before you travel. Beyond that, I found that Equal Eats translation cards are very high quality and can be bought as a hard plastic card or a printable that you can laminate.
Cruises and EpiPens
Cruises need extra planning.
Bring more medication than you think you need because replacing prescriptions at sea is not easy.
Tell the cruise line in advance about severe allergies. They usually have a medical form that they want you to fill out so that they have as much information as possible upfront.
Buffets can be difficult because of cross-contamination, so sometimes speaking directly with the dining team helps.
Always keep EpiPens with you during shore excursions too – not left in the cabin.
Flying With EpiPens FAQ
Can you bring an EpiPen on an airplane?
Yes, you can bring an EpiPen on an airplane and it should always travel in your hand luggage, not checked baggage. If an allergic reaction happens during the flight, you need immediate access to it. Most airlines and airport security staff are used to seeing adrenaline auto-injectors like EpiPens, Jext and Emerade.
Do you have declare an EpiPen when flying?
You do not usually need to formally declare an EpiPen at airport security, but it is a good idea to mention it if asked or if you are also carrying liquid medication. Keeping it in its original box with the prescription label and a doctor’s letter makes the process much easier, especially for international travel or stricter destinations.
Can you fly with injection pens?
Yes, you can fly with injection pens including EpiPens, insulin pens, Mounjaro pens and other prescribed injectables. These should be carried in your cabin bag with supporting paperwork if possible. Some medications may need extra documentation depending on the country you are travelling to, especially if they are controlled or temperature-sensitive.
How many EpiPens can I travel with?
Most people should travel with at least two EpiPens per person, as many allergy specialists recommend carrying a backup in case a second dose is needed. For longer trips, cruises or destinations where replacing medication would be difficult, many families choose to travel with three or four. There is no fixed airline limit for personal medical use, but carrying a prescription copy helps explain why you have extras.
Which airlines carry EpiPens?
Many major airlines carry emergency medical kits onboard, and these may include adrenaline for severe allergic reactions, but you should never rely on the airline’s supply instead of bringing your own EpiPens. Policies vary by airline, and cabin crew are not a replacement for your own emergency plan. Always travel with your prescribed medication and inform the airline in advance if your allergy is severe.
Can EpiPens go through airport security?
Yes, EpiPens can go through airport security without any problem. They are classed as medically necessary items and can stay in your hand luggage. You do not usually need to place them in the standard liquids bag, but security staff may inspect them. Keeping them easy to access and travelling with a doctor’s letter helps avoid delays.
Flying with EpiPens is absolutely manageable, but it requires planning.
We do not leave the house – let alone the country – without checking where the EpiPens are first, and always check their expiry date too. The last thing you want is for it to go out of date while you are out of the country.
For families managing autism, food allergies, sensory challenges and restricted diets all at once, preparation is everything.
It is not about being over-prepared.
It is about making sure your child is safe so the holiday can actually feel like a holiday.
Because peace of mind travels too.
