How to Travel with Severe Food Allergies
A Step-by-Step System

Step 1: Before you leave

Talk to your allergist

Before any international trip, get a documented allergy action plan from your allergist. This serves two purposes: it gives you a clear protocol if you react, and it gives you documentation in English that you can show to doctors abroad. Ask specifically for a letter that confirms your allergy, lists your prescribed medications including epinephrine, and states your typical reaction pattern.

If you're traveling somewhere with a significant language barrier, ask your allergist if they can provide the letter in translated form, or use a certified medical translation service. A Thai ER doctor should not have to diagnose your allergy from a letter they cannot read.

Check medication rules for every destination

Epinephrine is legal to carry in most countries but rules differ for how much you can bring and whether you need documentation. Research each country before you travel. The safest approach is to carry a copy of your prescription alongside your auto-injectors. Store medications in the original labeled packaging.

Also check whether your specific epinephrine brand is available at pharmacies in your destination. If you lose or use your auto-injectors, knowing the local equivalent saves critical time. EpiPen is widely recognized; other brands like Jext and Emerade are more common in Europe.

Build your allergy cards

You need a written allergy card in the local language for each country you're visiting. Not an app. Not a screenshot of Google Translate. A formatted card that specifies your allergens clearly, lists derivative ingredients (not just the obvious ones), and communicates severity.

The difference matters: "I am allergic to peanuts" in Thai communicates the allergen. A well-structured card adds: hidden sources like peanut oil in stir-fry sauces, the severity level, and a request not to use shared cooking utensils. That second layer is what actually changes kitchen behavior.

AllergyPass generates free multilingual allergy cards for over 20 languages. Print one for each destination, and save a digital version on your phone.

Research hospital locations

For each city you're visiting, identify the closest hospital with a 24-hour emergency department. Save the address and phone number offline. In a reaction situation you may not have internet access, a working phone signal, or the presence of mind to search. Having it saved removes one variable.

In major Asian cities, international hospitals are often the most accessible option for English-speaking travelers: Bangkok Hospital, Bumrungrad (Bangkok), Raffles Hospital (Singapore), St. Luke's (Manila). In rural areas, research in advance or ask your accommodation on arrival.

Step 2: What to pack

The full kit:

• Two epinephrine auto-injectors: carry-on only, at body temperature where possible
• Antihistamines: for mild reactions; do not substitute for epinephrine in severe reactions
• Doctor's letter: English plus translated version for primary destination
• Allergy cards: printed and digital, one per destination language
• Medical ID: bracelet or card listing your allergy and emergency contact
• Safe snacks: for airports, long transit, and destinations with limited safe options
• Hospital addresses: saved offline for each city

Temperature matters for epinephrine: auto-injectors should be kept between 15 and 25 degrees Celsius and away from direct light. Do not store in checked luggage (temperature uncontrolled) or in the pocket of a jacket left in a hot car.

Step 3: Communicating at restaurants

This is where most allergy incidents happen. The gap is almost always communication, not malice. A kitchen that doesn't understand the scope of your allergy will use shared utensils, add a sauce that contains your allergen without thinking, or confirm "no peanuts" while missing that the oil is peanut-based.

Step 4: Travel insurance for allergic reactions

This is the step most people skip until they need it. Emergency treatment for anaphylaxis abroad ranges from manageable to expensive depending on the country, hospital, and your coverage. In the US, a single ER visit for anaphylaxis can cost several thousand dollars without insurance. In Southeast Asia, costs are lower but still significant without coverage, particularly if you need observation or hospitalization.

SafetyWing Nomad Insurance is one of the more traveler-friendly options for this: it covers emergency medical care including allergic reactions, is available monthly without long-term commitment, and does not treat allergies as a pre-existing exclusion the way some annual policies do. It is designed for people who travel continuously or for extended periods, which makes it practical for long trips through multiple countries.

For standard one- or two-week trips, most comprehensive travel insurance policies from major providers will cover emergency anaphylaxis treatment. Read the exclusions carefully before you buy.

Step 5: If something goes wrong

Having a plan in place before you need it is the difference between a managed emergency and a chaotic one.

• Use epinephrine first: antihistamines do not stop anaphylaxis, they treat mild symptoms only
• Lie down with legs elevated: unless breathing is difficult, in which case sit upright
• Get to a hospital regardless of initial improvement: biphasic reactions (a second wave) can occur hours later
• Show your doctor's letter: it confirms your allergy and prescribed medications to local medical staff
• Contact your insurance provider's emergency line: most have 24-hour assistance; they can coordinate care and arrange evacuation if needed

Tell your travel companions before the trip what to do if you react, where your epinephrine is, and what your reaction looks like. If you are traveling alone, consider wearing a medical ID and keeping your doctor's letter accessible on your phone home screen or lock screen note.

How allergy risk varies by destination

Not all destinations carry the same risk level. The variables are allergen prevalence in local cuisine, kitchen practices around cross-contamination, and how reliably your card and communication will be understood.

Destination-specific guides with full hidden allergen breakdowns are available for each of these: Thailand, Japan, Vietnam, Bali, and France.

Frequently asked questions

Can you travel internationally with a severe food allergy?

Yes, with preparation. The key requirements are: epinephrine (and a backup), translated allergy cards for every destination, a basic emergency plan for each city, and travel insurance covering anaphylaxis. Millions of people with severe allergies travel internationally each year. The risk is real and manageable.

What should I bring when traveling with a food allergy?

The minimum: two epinephrine auto-injectors in your carry-on, antihistamines, a written allergy card in each destination's language, a doctor's letter, and travel insurance that covers emergency medical care. Useful additions: a medical ID bracelet, offline hospital addresses for each city, and safe snacks for transit.

How do I communicate a food allergy abroad?

A written card in the local language is the most reliable method. It removes the language barrier, communicates severity, and specifies derivative ingredients. Show it before you order, not after. AllergyPass generates free multilingual cards formatted specifically for restaurant communication.

Does travel insurance cover food allergy reactions?

Most comprehensive travel insurance policies cover emergency medical treatment including anaphylaxis. Check for pre-existing condition exclusions (some policies list allergies), verify medical evacuation is included, and confirm there is a 24-hour emergency assistance line. SafetyWing Nomad Insurance covers emergency allergic reactions without treating allergies as a pre-existing exclusion.

Should I carry two EpiPens?

Yes. A second reaction (biphasic anaphylaxis) can occur after the first dose wears off before emergency care arrives. Both auto-injectors belong in your carry-on, not checked luggage. For remote destinations, discuss carrying three with your allergist.
