Thank you for taking the time to contact the Thai FDA office. I would like to inform you that Clozepine is classified as a medical preparations according to the Drug Act B.E. 2510 (1967).
So, if a patient under treatment is allowed to bring those medications into Thailand for personal use in a quantity NOT EXCEEDING 30 DAYS OF PRESCRIBED USAGE when accompanied by a valid prescription and/or medical document from the prescribing physician.
Therefore, you don't need the permit for medical preparations from Thai FDA. However, please keep the medications in the original packaging along with prescription and/or medical document from the prescribing physician between you stay in Thailand. However, they are not narcotics. So they are not under our responsibility.
