Medical Device PMS Oversight for Thai FDA
Compliance and Market Continuity - Thailand
Maintaining compliance, safety, and reliability for medical devices in Thailand requires continuous regulatory oversight and familiarity with Thai FDA expectations. After a device is approved and distributed, manufacturers and appointed local representatives must continue to meet post-market obligations under Thailand’s regulatory framework.
Post-Market Surveillance (PMS) in Thailand provides the structure for monitoring device performance after market entry. It includes complaint documentation, incident review, reporting responsibilities, and corrective action management in accordance with Thai FDA requirements.
At Andaman Medical, we manage these post-market responsibilities on your behalf. Our team works closely with Thai regulatory requirements to maintain proper documentation, coordinate reporting activities, and support ongoing compliance throughout the product lifecycle.
Why Medical Device PMS Matters in Thailand
Post-Market Surveillance (PMS) is a critical component of Thailand’s medical device regulatory system once products are available on the market.
Manufacturers and local representatives are expected to maintain complete records, evaluate reported issues, and fulfill regulatory reporting obligations under Thai FDA guidelines.

Medical Device PMS Requirements in Thailand
As part of post-market surveillance of medical devices, Thailand requires the reporting of medical device defects or adverse events (AEs) affecting any person, whether the incident occurs within Thailand or abroad, when the medical device is suspected to be a contributory cause. The reporting is required for the following criteria:
- serious threat to public health incidents
- death or serious injury
- if scientific data or evidence indicates that the incident can lead to death or serious harm to consumers if it were to recur.
In order to reduce or eliminate the risks associated with the medical device defect or AE which can result in a serious threat to public health or imminent risk of death or serious harm, the surveillance and reporting of a FSCA is required when the Product Owner undertakes any of the following actions either in Thailand or outside Thailand:
- product recall
- device modification
- product exchange
- device destruction
- safety notification updates and changes.
In order for the Thailand’s FDA to adequately evaluate the cause of the medical device defect or AE, and the subsequent FSCAs, the following information is required as a minimum for the reporting:
- description of the device defect or AE, and FSCA
- place where the device defect or Adverse Effect occurred
- persons affected by the incident (only for AE)
- health hazard evaluation report or any related documents, together with the initial report (only for FSCA).
The Adverse Effect and FSCA reports can be submitted via the online Medical Device Problem Reporting System on the Health Product Vigilance Centre website.
