What additional security and record-keeping requirements apply when handling and storing controlled “dangerous drugs” (Dangerous Drugs)?

In Hong Kong, medicines controlled under the Dangerous Drugs Ordinance (Cap. 134), such as certain potent painkillers and psychiatric medicines, are subject to stricter controls than ordinary prescription medicines. Security: these medicines must be stored in a sturdy, locked metal cabinet or safe, securely fixed to the building structure. Only authorised designated personnel (usually pharmacists) may hold the key or combination. Records: every transaction must be recorded by hand, in real time, in a dedicated, firmly bound Dangerous Drug Register. Each entry must include the date; the name and address of the person or organisation from whom the drugs are received or to whom they are supplied; details of the authorising document (such as a doctor’s prescription); and the quantity involved and balance remaining. Records must not be altered. Errors should be corrected by drawing a line through them and signing the correction.
