Q42 · Category A: Pharmacy licensing system and regulatory foundations (Q1-Q50)
Combination products containing both Western and Chinese medicines are subject to very close scrutiny in Hong Kong and are usually classified and regulated as Western medicines. Under the Pharmacy and Poisons Ordinance, any product containing a Western medicine ingredient listed in the Poisons List is classified as a “pharmaceutical product”, whether or not it also contains Chinese medicine ingredients. Such a product must therefore follow the full Western medicine regulatory pathway: it must be registered with the Pharmacy and Poisons Board (PPB) (and obtain an HK-XXXXX number), and its manufacturer, importer and distributor must hold the relevant Western medicine licences, such as a manufacturer’s licence or wholesaler’s licence. In assessing the product, the regulator will evaluate the safety and quality of both its Western and Chinese medicine ingredients. Claiming that a product is “all natural” or “herbal” when it has been found to contain illegally added Western medicine ingredients is an offence that regulators crack down on severely.

📘 Regulatory basis

The definition of “pharmaceutical product” in section 2 of the Pharmacy and Poisons Ordinance is key. Any product containing a regulated Western medicine ingredient falls within the scope of the Ordinance, regardless of the quantity. This takes precedence over the application of the Chinese Medicine Ordinance.

📗 Drew Tang's recommendations

If you plan to develop or import combination products containing both Western and Chinese medicines, you must consider compliance from the research and development stage. We recommend a comprehensive ingredient analysis and legal assessment to determine the regulatory pathway in Hong Kong and devise a registration and market launch strategy accordingly.

📕 Risk notice

Illegally adding western medicines to unapproved proprietary Chinese medicines or health products (such as “paracetamol” for pain relief, “sibutramine” for weight loss or “sildenafil” for sexual enhancement) is extremely dangerous and a serious offence. It poses a direct threat to consumers’ health and may result in the most severe criminal penalties.
