Panbesy is a brand of phentermine sold in Thailand. Phentermine is an appetite suppressant (sympathomimetic) used for short-term treatment of obesity. It is supplied in Thailand under Thai FDA controlled-substance permits. Brand names differ between countries, so outside Thailand ask for phentermine by name (other brands include Duromine).
Is Panbesy available in Thailand?
Yes. Panbesy is supplied in Thailand under controlled-substance permits issued by the Thai FDA Narcotics Control Division. The most recent permit on record is from 2024. As a controlled medicine it is dispensed through hospitals and licensed clinics rather than ordinary pharmacies.

Phentermine is a controlled substance, so it is not on the ordinary medicine register. These products are imported or made under permits and certificates from the Thai FDA Narcotics Control Division.
