Food Allergies in Vietnam: Epinephrine Auto-Injector Availability and Hidden Allergens
Vietnam's cuisine relies heavily on fish sauce, shrimp paste, and peanuts. Know what to bring, where to find care, and how to communicate in an emergency.
What changes when you travel to Vietnam with food allergies
Fish sauce (nước mắm), shrimp paste, and peanuts appear across Vietnamese cuisine as foundational flavourings, not just garnishes, and they are frequently invisible in cooked dishes and marinades[7]. Epinephrine auto-injectors (EAIs) such as EpiPen are not reliably available at retail pharmacies in Vietnam, making it critical to bring a sufficient supply from home. Vietnam has no mandatory pre-packaged allergen-labelling law equivalent to EU or US standards, so the burden of verification at every meal falls entirely on you[6].
This guide covers medication import rules, what antihistamines and emergency epinephrine are available locally, how to find an allergist or immunologist in Vietnam, how to communicate your allergy in Vietnamese, and what to do if anaphylaxis occurs. Storing your allergy profile, medication list, and emergency phrases in your Nomedic International Patient Summary (IPS) means any clinician can access your full picture instantly, without a language barrier.

Key risks
Key risks for food allergies travellers in Vietnam
Epinephrine auto-injectors are not routinely stocked at pharmacies
EAIs are available in only 60% of countries surveyed globally, mainly in high-income countries, and Vietnam is not confirmed among those with reliable retail supply. Do not rely on sourcing them locally.
Hidden allergens in fish sauce, shrimp paste, and peanuts
Fish sauce (nước mắm) is used as a marinade, cooking ingredient, and dipping sauce across meat, poultry, and vegetable dishes, not only seafood. Shrimp paste and dried prawn powder can be added to broths and soups without appearing on any menu description. Always ask about these specifically by name.
Cross-contamination risk from shared woks and cooking oil
Vietnamese kitchens frequently use shared woks that are not washed with detergent between uses, and reused cooking oil compounds cross-contact risk. For anaphylaxis-level fish or shellfish allergies, even dishes nominally free of those ingredients carry a measurable contact risk.
Limited awareness of food allergy severity among restaurant staff
The concept of life-threatening food allergy is not widely understood in Vietnamese food-service settings. A verbal request to omit an ingredient is frequently interpreted as a preference, not a medical requirement. Carrying a printed or digital allergy card in Vietnamese is essential, but even this does not guarantee safe food preparation at street food stalls.
Medication import limits for corticosteroids and other prescription drugs
Corticosteroids such as prednisolone are listed among medications requiring customs declaration and supporting documentation in Vietnam. Narcotic and psychotropic drugs are capped at 7 and 10 days respectively; standard allergy medications do not fall into those categories.
Preparation checklist
- Confirm your epinephrine auto-injector supply — Bring at least two EAIs per person; auto-injectors are not reliably available at Vietnamese retail pharmacies.
- Get a physician letter for all prescription allergy medications — The letter must state your name, diagnosis, medication name (INN and brand), dose, and the prescribing doctor's contact details.
- Obtain your Nomedic IPS before departure — Your IPS stores allergen triggers, medication list, and emergency contacts in a format readable by any clinician worldwide, including offline QR access.
- Prepare a Vietnamese allergy card — Include the specific allergens in Vietnamese script (e.g., không có nước mắm for no fish sauce, không có đậu phộng for no peanuts); print and save digitally.
- Research allergy-aware and strict vegetarian/vegan restaurants at each destination — Locate options in Hanoi, Ho Chi Minh City, and Da Nang before travel; book ahead where possible.
- Book an allergist consultation before departure — Confirm your anaphylaxis action plan is current and appropriate for a destination where EAI resupply is uncertain.
- Pack antihistamines in your carry-on — Cetirizine and loratadine are available in Vietnam under brand names including Cetirizine STADA and Clarityne, but bring adequate supply from home.
- Check your EAI expiry dates — EpiPen has a shelf life of approximately 18 to 20 months from manufacture; replace any unit expiring during or shortly after your trip.
- Identify the nearest hospital with an allergy or immunology unit at each stop — Vinmec International Hospital (Hanoi and Ho Chi Minh City) has a World Allergy Organization-accredited Allergy and Clinical Immunology Centre.
- Save emergency numbers offline — Vietnam ambulance: 115, police: 113, fire: 114. Save these in Nomedic before you lose mobile data.
Documents to carry
Documents to carry when travelling to Vietnam with food allergies
Keep the following accessible on your phone and in printed form; the Nomedic app consolidates the most critical items into a single shareable record.
Your International Patient Summary (IPS)
Your Nomedic IPS holds your confirmed allergen list, current medications (INN and brand name), allergy action plan, and emergency contacts in a standardised format that any clinician worldwide can read. In a Vietnamese emergency department, where English is not guaranteed, handing over a QR-linked IPS removes the need to explain your diagnosis verbally and reduces the risk of a clinician missing a critical trigger.

Medications advice
Bringing your food allergy medications to Vietnam
Vietnam permits travellers to bring personal-use medicines into the country provided they are kept in original packaging, carry a matching prescription, and are accompanied by a physician letter. Narcotic drugs are capped at a 7-day supply and psychotropic drugs at a 10-day supply; standard allergy medications including antihistamines, corticosteroids, and epinephrine do not fall under those categories, but corticosteroids must be declared at customs with supporting documents. Keep documents accessible in your carry-on, not checked luggage.
Do not post your medication to Vietnam.
Postal import of pharmaceuticals is prohibited under Vietnamese pharmacy law. All medications must be carried in person in hand luggage with matching documentation.
Food allergy medications: brand names, INNs, and Vietnam availability
Antihistamines are available over the counter at Vietnamese pharmacies (nhà thuốc) under the brands below; epinephrine auto-injectors are not reliably stocked at retail pharmacies and should be brought from home in sufficient quantity.[2]
Carry EAIs from home. Hospital emergency departments hold epinephrine ampoules.
Available OTC at major pharmacy chains including Pharmacity and Long Chau.
Available OTC. Widely stocked.
Available OTC at major chains.
Requires customs declaration and physician letter on entry. Available at pharmacies with prescription.
Available OTC; first-generation antihistamine, causes sedation.
Sedating antihistamines and travel safety
First-generation antihistamines such as chlorphenamine (Clorpheniramine) are sold OTC at Vietnamese pharmacies and cause significant sedation. If you are driving or on a boat tour, use a non-sedating second-generation agent (cetirizine, loratadine, fexofenadine) instead. Confirm with your prescribing clinician which agent is appropriate for your allergy type before you travel.
Travelling with epinephrine auto-injectors
These steps apply regardless of which airports or regions of Vietnam you transit through.
Your medication list, ready to share.
Nomedic stores your medication name, INN, dosage, and frequency, readable by any clinician worldwide.
At your destination
Healthcare and prescriptions in Vietnam
Vietnam has a public health system (Bảo hiểm y tế) that covers Vietnamese nationals; international travellers have no reciprocal agreement entitlement and must use private or international clinics. A specialist consultation at a private hospital such as Vinmec or Hoan My costs between 500,000 and 2,900,000 VND (~$20 to ~$114 / ~€18 to ~€104) depending on the facility and whether you use the international-patient pathway[4]. Foreign prescriptions are not formally accepted by most retail pharmacies; pharmacists will typically suggest an equivalent local brand or refer you to a clinic.
Antihistamines (cetirizine, loratadine, fexofenadine) are available over the counter at pharmacy chains including Pharmacity and Long Chau in major cities. Prednisolone and other corticosteroids require a Vietnamese prescription at retail pharmacies, though private clinics can issue one after a consultation. Epinephrine ampoules are held in hospital emergency departments but are administered by clinical staff; the auto-injector format is not stocked at retail.
Emergency epinephrine is dispensed differently from antihistamines
If you have used your auto-injector and need emergency replacement, go directly to the emergency department (cấp cứu) of a major hospital. Bring your IPS and physician letter. Hospital pharmacies in Vietnam hold epinephrine ampoules for clinical use; retail pharmacies do not stock EAIs.
Finding a food allergy specialist
Allergists and clinical immunologists (bác sĩ chuyên khoa dị ứng - miễn dịch) practice within the allergy and immunology departments of major private hospital groups. Vinmec International Hospital in Hanoi and Ho Chi Minh City holds a World Allergy Organization Centre of Excellence accreditation as of 2025[5], and its staff follow EAACI and WAO anaphylaxis management protocols. Appointments at Vinmec require booking in advance; walk-ins are accepted at the emergency department for acute reactions. Identify the nearest allergy centre before you travel and save the address offline. Use Nomedic's provider search to find a specialist near your destination.
Search for providers near your destination
Use Nomedic's provider search to find food allergy specialists in Vietnam. Save the address and phone number offline before you travel.
If you use your epinephrine auto-injector in Vietnam
Using your EAI buys time but does not replace emergency care. Every anaphylactic episode that requires epinephrine requires immediate transfer to hospital, regardless of how quickly symptoms resolve after the dose.
Managing hidden allergens and cross-contamination day to day
Fish sauce (nước mắm) is used as a foundational flavouring in the majority of Vietnamese dishes, including those nominally free of seafood. Nước mắm is added to marinades, dipping sauces, stir-fries, and soups across all meal types, including salads, spring rolls, and noodle dishes; shrimp paste and dried prawn powder can be added to broths without menu disclosure.
Use these strategies at every meal. At sit-down restaurants with English menus, show your printed Vietnamese allergy card before ordering and ask the server to confirm with the kitchen. At vegetarian and vegan restaurants (nhà hàng chay), verify that no animal-based sauces including fish sauce are used on the premises; strict Buddhist vegan establishments are the safest option for fish and shellfish allergies. Avoid street food stalls where shared cooking equipment (woks, oils, utensils) creates unavoidable cross-contact. In supermarkets such as Co.op Mart or WinMart, check packaged food labels for nước mắm or mắm ruốc (shrimp paste) listed in ingredients. Peanuts (đậu phộng) are found in many dessert and snack items even when not prominently advertised.
An allergic reaction is not always immediate
A delayed response after a meal does not mean the food was safe. If you develop urticaria, swelling, or throat tightness within two hours of eating, treat as a potential reaction and follow your anaphylaxis action plan. If symptoms progress or do not resolve with antihistamine within 30 minutes, use your EAI and call 115.
Vietnamese phrases for clinicians
Show your Nomedic IPS first, it removes the need to explain your diagnosis verbally. If verbal communication is needed:
“Tôi bị dị ứng thực phẩm nghiêm trọng.”
I have a severe food allergy.
“Tôi đang bị phản ứng dị ứng nghiêm trọng. Tôi cần tiêm adrenaline ngay.”
I am having a severe allergic reaction. I need epinephrine immediately.
“Tôi cần gặp bác sĩ chuyên khoa dị ứng.”
I need to see an allergist.
“Tôi không ăn được nước mắm, tôm, cá hoặc đậu phộng.”
I cannot eat fish sauce, shrimp, fish, or peanuts.
“Bệnh viện có khoa dị ứng gần đây nhất ở đâu?”
Where is the nearest hospital with an allergy department?
“Tôi cần thuốc kháng histamine khẩn cấp.”
I need emergency antihistamine medication.
Insurance considerations
What to know about travel insurance
Anaphylaxis treatment at a private hospital in Vietnam, including ambulance, emergency resuscitation, and overnight admission, can exceed 50,000,000 VND (~$1,960 / ~€1,800) per episode. A policy that lists 'pre-existing conditions covered' without naming food allergies explicitly may still refuse an anaphylaxis claim.
What to look for in a policy
Not just 'pre-existing conditions'. Your condition should appear on the policy schedule.
Covers transfer to a higher-level facility or repatriation if local care is insufficient for a severe reaction.
Covers the cost of replacing epinephrine auto-injectors lost, expired, or used on the trip.
Essential so your insurer can communicate directly with treating clinicians in Vietnamese hospitals.
What to declare at application
Declare thoroughly. Incomplete disclosure can invalidate your entire policy, not just the food-allergy-related claim.
State whether your allergy is IgE-mediated and list each confirmed trigger (fish, crustacean, peanut, tree nut, etc.).
Use the INN alongside the brand name for each: epinephrine, cetirizine, prednisolone, or other prescribed agents.
Insurers use this to assess risk level; omitting a recent event can void the policy.
Declare any co-existing asthma, eczema, or other atopic conditions, as these affect anaphylaxis severity and underwriting decisions.
Your policy number and emergency assistance line, saved alongside your IPS and accessible offline.
Vietnam has no reciprocal healthcare agreement with EU or EEA states. An EHIC or GHIC card provides no entitlement to reduced-cost or free care in Vietnam. EU and EEA travellers require private travel insurance with explicit food allergy cover to access treatment at international-standard facilities.
Emergency protocol
Immediate steps at or before the emergency department
Anaphylaxis may present as throat tightening, severe urticaria, vomiting, dizziness, or circulatory collapse within minutes of allergen exposure. If you carry an epinephrine auto-injector and symptoms are progressing, administer it immediately and call 115. Contact your travel insurer's assistance line as soon as you are safe to do so to authorise hospital admission.
When you arrive, follow in order
Full clinical picture in seconds, no verbal explanation needed.
Hand your phone to the triage nurse:
Tôi đang bị sốc phản vệ. Tôi cần tiêm adrenaline ngay.
I am in anaphylactic shock. I need epinephrine immediately.
Tell the clinician the time and dose of any EAI used before arrival; show the used device if possible.
Your Nomedic IPS includes this; point to the allergen section so triage staff can identify the trigger and inform treatment decisions.
Calls and location
Ambulance: 115. Police: 113. Fire: 114. In major cities, state a nearby landmark or hotel name to help dispatchers locate you. Ride-hailing apps (Grab) can reach international hospitals faster than waiting for an ambulance in heavy city traffic; tell the driver cấp cứu (emergency) and the hospital name.
In hospital
Some injectable medications and IV fluids contain latex, preservatives, or excipients that may trigger a secondary allergic response. Show your full allergen list from your Nomedic IPS to every clinician who prescribes or administers a new medication during your admission.
After any emergency
Before you leave the hospital if possible, to review what occurred and adjust your action plan.
Required for insurer reimbursement and for continuity of care with your home allergist.

Frequently asked questions
Can I bring my food allergy medications into Vietnam?
Standard allergy medications including epinephrine auto-injectors, antihistamines, and corticosteroids may be brought into Vietnam for personal use, provided they are in original packaging with a matching physician letter and prescription. There is no fixed day-limit for standard allergy medications, but bring only what you need for the duration of your trip.
Do not post medications to Vietnam
Postal import of pharmaceuticals is prohibited. All medications must travel with you in hand luggage.
Are food allergy medications available at Vietnamese pharmacies?
Antihistamines such as cetirizine (Cetirizine STADA, Zyrtec) and loratadine (Clarityne, Loratadin STADA) are widely available over the counter at major pharmacy chains including Pharmacity and Long Chau in Hanoi, Ho Chi Minh City, and Da Nang. Epinephrine auto-injectors are not reliably stocked at retail pharmacies; hospital emergency departments hold epinephrine ampoules for clinical administration. Bring your full supply of EAIs from home and do not depend on sourcing them locally.

How can I communicate my food allergy diagnosis in an emergency in Vietnam?
Show your Nomedic IPS first. If verbal communication is needed:
“Tôi bị dị ứng thực phẩm nghiêm trọng.”
I have a severe food allergy.
“Tôi đang bị phản ứng dị ứng. Tôi cần tiêm adrenaline ngay.”
I am having an allergic reaction. I need epinephrine immediately.
How do I avoid hidden allergens in Vietnamese food?
Fish sauce (nước mắm) and shrimp paste (mắm ruốc) are used as foundational flavourings across Vietnamese cuisine, including in dishes that contain no visible seafood. Peanuts (đậu phộng) appear as toppings and in sauces in salads, spring rolls, and noodle dishes. Always show a Vietnamese allergy card before ordering, eat at strict vegetarian or vegan establishments (nhà hàng chay) where possible, and avoid street food stalls with shared cooking equipment.
Key Vietnamese allergen terms
Không có nước mắm = no fish sauce. Không có đậu phộng = no peanuts. Không có tôm = no shrimp. Không có hải sản = no seafood. Print these on your allergy card.
Do I need special travel insurance to visit Vietnam with food allergies?
Standard travel policies frequently exclude pre-existing conditions including food allergies, or impose sub-limits that do not cover a full anaphylaxis treatment episode. An international clinic hospitalisation in Vietnam can exceed 50,000,000 VND (~$1,960 / ~€1,800), and Vietnam has no reciprocal healthcare agreement with any country, meaning all costs are out of pocket without adequate insurance.
Declare thoroughly
State your allergy type, confirmed triggers, current medications, last anaphylactic episode date and severity, and any co-existing asthma or atopic conditions. Incomplete disclosure invalidates the entire policy.
