Can you bring Lisdexamfetamine (Vyvanse, Elvanse) to Thailand?
Assume no. Vyvanse turns into dexamfetamine, a banned Category 1 narcotic in Thailand, and it is not available locally.
Bringing it into Thailand
Banned, even with a prescription
Thai FDA traveller guidance does not name lisdexamfetamine. The body converts it into dexamfetamine, which Thai FDA lists as a banned Category 1 narcotic, and clinic and customs-guide sources say Vyvanse is prohibited. Treat it as banned: do not bring it unless Thai FDA confirms otherwise in writing (Narcotics Control Division, tnarcotics@fda.moph.go.th).
Getting it in Thailand
Not legally available in Thailand
Lisdexamfetamine is not prescribed in Thailand, according to a Bangkok clinic's ADHD guide. Methylphenidate is the usual stimulant alternative, prescribed after a Thai psychiatrist's assessment.
