Bringing Medications into Vietnam 2026: Rules, Declarations & What to Declare
General Rules: Medications for Personal Use
Vietnam’s customs authority (Tổng cục Hải quan) allows travelers to bring medications for personal use without special permits, subject to these conditions:
- Quantity: Sufficient for the duration of your trip, typically interpreted as up to 30 days’ supply. More than 30 days’ supply may raise questions at customs.
- Original packaging: Keep medications in their original pharmacy packaging with the label attached. This establishes what the medication is and what dose.
- Prescription letter: Not strictly required for non-controlled medications, but having one is strongly recommended. A letter from your doctor on official letterhead stating your name, the medication, dose, and diagnosis is the best documentation.
- Declaration: Standard over-the-counter medications (antihistamines, paracetamol, ibuprofen, vitamins) do not need to be declared at customs. Prescription medications — especially controlled substances — should be declared.

Practical Tips for Traveling with Medications
- Get a doctor’s letter: For any prescription medication, ask your doctor for a signed letter on official letterhead in English. Include: patient name, medication name (generic and brand), dosage, condition being treated, and duration of treatment.
- Keep medications in hand luggage: Never check controlled medications in hold luggage. Carry them in your hand baggage in original packaging.
- Liquid medications: Subject to the 100ml per container, 1-litre bag liquid rule on flights. Liquid medicines (insulin, liquid antibiotics) are exempt from the 100ml rule if you inform security and carry a prescription.
- CBD and cannabis products: Completely prohibited in Vietnam regardless of legality in your home country. Do not bring CBD oil, cannabis-derived products, or similar items — even if prescription-grade in your country.
- Online verification: Vietnam’s Ministry of Health publishes a list of controlled substances (narcotics). For specific medications not covered here, check with the Vietnamese Embassy in your country or consult a travel medicine doctor before departure.
