Vyvanse / Lisdexamfetamine → 🇹🇭 Thailand

Full details

Vyvanse / Lisdexamfetamine prohibited; penalties for import. Quantity guidance for Thailand: Not approved by Thai FDA — lisdexamfetamine is a Schedule I narcotic in Thailand; any quantity is prohibited. Documentation: No permit issued — Thai FDA does not authorise personal import of unapproved Schedule I narcotics. Enforcement in Thailand carries fines from THB 50,000 to THB 500,000 and imprisonment up to 10 years in aggravated cases under Customs Act B.E. 2560 s.242-244; Narcotics Act. Because vyvanse / lisdexamfetamine is prohibited rather than restricted, there is no permit route for an ordinary traveller — attempted import is treated as smuggling regardless of intent. Arrival checks are carried out by Thai Customs Department; when in doubt use the declare (red) channel — declared goods at worst attract duty or surrender, while undeclared goods attract penalties. Leaving Thailand with vyvanse / lisdexamfetamine is a separate question: restricted — Vyvanse (lisdexamfetamine) is a controlled stimulant; personal export from Thailand requires prescription documentation and stays within personal-use limits.

ENFORCEMENT

Occasional — Enforcement reported intermittently.

Leaving Thailand with vyvanse / lisdexamfetamine

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.
