πŸ’Š The Number Nobody Tells You
Vietnam lets you bring controlled medication for your own treatment without an import licence β€” but only 7 days’ supply for narcotic drugs and 10 days’ supply for psychotropic drugs, at the dose on your prescription. Both must be declared at customs. A month’s supply for a month-long trip is over the line.

Almost every guide to bringing medication into Vietnam says some version of “bring a reasonable amount for personal use and carry your prescription.” That advice is not wrong, but it is dangerously incomplete, because for one specific group of medicines the law puts an actual number on “reasonable” β€” and the number is far smaller than what people instinctively pack.

If you take a benzodiazepine for anxiety, an opioid for pain, a stimulant for ADHD or a prescription sleeping tablet, this page is about you. If you take an SSRI, blood pressure medication, insulin or an antihistamine, you are almost certainly outside this rule β€” the general medication guide covers your situation.

The Two Limits

Under Decree 54/2017/ND-CP, an individual entering Vietnam may bring medication for their own treatment without an import licence, subject to a ceiling measured in days:

CategoryCeiling without a licenceMust declare?
Narcotic drugs7 days’ supply at the prescribed doseYes
Psychotropic drugs10 days’ supply at the prescribed doseYes
Drug precursors10 days’ supply at the prescribed doseYes
The ceiling is not an entitlement You may carry the lesser of two amounts: the days above, or whatever your prescription actually covers. If your prescription is written for five days, five days is your limit β€” the 10-day figure does not top it up.

The arithmetic is what makes this worth knowing. A month in Vietnam with a nightly sleeping tablet means 30 tablets in your bag. The ceiling is 10. You are not slightly over; you are at triple the limit, in a category the authorities take seriously.

Which Category Is My Medication In?

This is the question that decides everything, and it has an uncomfortable answer: the classification that matters is Vietnam’s, not your own country’s. A drug that is unscheduled where you live can sit on a Vietnamese control list, and the reverse is also true.

Vietnam’s Ministry of Health publishes three lists β€” narcotic substances, psychotropic substances, and precursors used as drugs. The Vietnamese embassy in your country publishes these lists in English and is the correct place to check a specific drug name.

🚫 We do not publish a drug-by-drug verdict You will find pages that list dozens of medicines with a tick or a cross beside each. We have deliberately not written one. These lists run to hundreds of substances plus variants and combination products, they change, and a single wrong entry here would send someone to a border with the wrong expectation. Check your drug name against the official list, or ask the embassy in writing.

That said, two broad families account for most of the cases where travellers get caught out:

  • Benzodiazepines β€” the anxiety and sleep medications. Diazepam, alprazolam, clonazepam, lorazepam and relatives. These sit in the psychotropic category.
  • Opioids β€” the stronger painkillers. Tramadol, codeine, oxycodone, morphine. These sit in the narcotic category, with the tighter 7-day ceiling.

Stimulant ADHD medication and prescription sleeping tablets also sit in controlled territory. If your medication belongs to any of these families, work on the assumption that the limits apply and verify the specific name before you fly.

What Your Prescription Must Actually Contain

A pharmacy label is not a prescription, and a photo on your phone is not documentation. The prescription you carry needs, at minimum:

  • Patient’s name and age
  • Drug name, strength or concentration, and volume
  • Quantity β€” or the number of days it covers
  • Dosage
  • Prescribing doctor’s full name and signature
  • The doctor’s address β€” hospital, clinic or centre

Separately, the medication itself must carry a label showing the drug name, active ingredients, concentration, content and expiry date. This is the practical reason to keep everything in original packaging rather than decanting a trip’s worth into a pill organiser.

βœ… Worth the small effort: get it translated A Vietnamese translation of your prescription is not legally required, but it removes the language step at exactly the moment you least want one β€” standing at a customs desk explaining what a drug is for. A translation costs little and takes a day.

If Your Trip Is Longer Than 7 or 10 Days

This is a normal situation, not an edge case, and there are two routes. Both run before you fly.

Route 1 β€” Declare in advance and get a decision

You can make a declaration to Vietnamese customs at the port of entry where you will arrive, supplying your itinerary and written proof of medical necessity from your doctor. Customs then decides whether to permit the larger quantity. Note the wording carefully: customs decides. This is discretionary permission, not a form you fill in and are waved through.

Route 2 β€” Arrange supply inside Vietnam

Contact a hospital in Vietnam before you travel and ask whether they can dispense your medication during your stay. For a stay of several months this is usually the cleaner answer than trying to carry the whole course. Hospitals in Hanoi, Ho Chi Minh City and Da Nang deal with foreign patients routinely.

What not to do Do not split a large quantity across bags, and do not remove medication from its labelled packaging to make it less obvious. Both turn an administrative question into something that looks like concealment β€” and concealment is what changes how the situation is treated.

At the Airport: Which Channel

Controlled medication goes through the Red Channel β€” the declare channel. This feels counterintuitive when you are carrying a legitimate prescription for your own illness, and many travellers walk the Green Channel assuming that declaring somehow implies wrongdoing.

It is the opposite. Declaring is what makes the medication lawful to carry. Walking past the declaration point with an undeclared controlled substance is the thing that creates the problem, regardless of how good your paperwork is.

Common Questions

Alprazolam is a benzodiazepine, which places it in the psychotropic category. It is legal to carry for your own treatment, capped at 10 days’ supply without an import licence, declared at customs, with a prescription. The usual problem is not legality β€” it is quantity.

Diazepam is also a benzodiazepine, so the same psychotropic rules apply: maximum 10 days’ supply, declared, with a prescription that names you, the drug, its strength, the quantity and the dose.

The ceiling is expressed in days of supply at the dose your prescription states. If your prescription says “as needed, up to one tablet daily”, ten tablets is ten days. Where a prescription is vague about frequency, ask your doctor to write the dosing explicitly β€” an ambiguous prescription is harder to assess at a counter, and the assessment will not be generous.

Yes. The limit is on what you bring into the country, not on which bag it travels in. Separately, it is worth keeping medication in your carry-on for a different reason β€” checked bags occasionally arrive a day late, and a controlled prescription is not something you can replace at a pharmacy on arrival.

Medication sent rather than carried falls under different rules again, with limits expressed in customs value and number of shipments per year. We have not set those out here because we could not verify how they are applied to controlled substances specifically. If this is your situation, ask the embassy before anyone posts anything.

πŸ“Œ Where this page stops We have given the two ceilings, the prescription requirements and the routes for a longer stay, because those are documented. We have not told you which category your specific drug is in, and we have not quoted a penalty for exceeding the limit β€” we could not verify enforcement practice for a traveller carrying a genuine prescription. For a definitive answer on a named medication, ask the Vietnamese embassy or consulate in your country in writing, and keep the reply.
