Taking vyvanse / lisdexamfetamine out of Thailand
Vyvanse (lisdexamfetamine) is a controlled stimulant; personal export from Thailand requires prescription documentation and stays within personal-use limits.
Details
Lisdexamfetamine is a Schedule II-equivalent controlled stimulant under the Narcotics Act B.E. 2522; Thai FDA export permit framework. Personal-use quantities (typically ≤30-90 days' supply) accompanied by the prescription and doctor's letter are generally permitted for export from Thailand; above these limits a Thai FDA export permit for scheduled drugs is required in advance. Destination-side treatment is the sharper risk — several countries (Japan requires advance permission; some jurisdictions ban amphetamine-class medicines outright) restrict arrival with stimulant ADHD medication, so verify the arrival rule for the same route.
