What medicines can international travelers bring into Vietnam, and what paperwork is needed for prescription or controlled drugs?

A small personal kit with paracetamol, ibuprofen, antihistamines, plasters, antiseptic and stomach remedies is normally suitable for travel to Nha Trang. Keep medicines in their original labelled packs rather than carrying loose tablets in a pill box.

For prescription medicine, bring only a travel-length supply and carry a prescription showing the generic drug name, dosage and your name. A separate doctor’s letter in English is particularly useful when the brand is unfamiliar in Vietnam.

Take extra care with codeine products, tramadol, strong opioid painkillers, benzodiazepines and sleeping pills, as they may be treated as controlled drugs. Carry medical documentation and confirm the current requirement with your airline, Vietnamese Customs or a Vietnamese consulate before flying.

Nha Trang has no separate medicine-import rules: checks occur when entering Vietnam, usually at your arrival airport. Avoid bringing an unexplained multi-month supply or transferring medication into unlabelled containers, as both can make customs questions harder to answer.
