If you are on chronic medication, do not leave with just a few days' worth of medication.
Discuss with your doctor before departure.
Ideally, bring:
- a reasonable supply;
- the prescription;
- the name of the active ingredient;
- the dosage;
- a medical summary if your situation requires it.
The French commercial name of a medication may be different in Vietnam.
The name of the active substance is therefore often much more useful.
