About this course

A practical, law-based course on prescribing, supplying, administering and storing controlled drugs in Singapore. It explains how the Misuse of Drugs Act 1973 and the Misuse of Drugs Regulations work with HSA licensing, MOH Circular 56/2019 on handling controlled drugs and the professional boards' codes, and turns the rules that matter most into everyday routines: valid prescriptions, the pharmacist's check, safe custody, registers, stock counts, wastage and witnessed destruction.

It is written for doctors, dentists, pharmacists, nurses and midwives, and for allied health professionals, optometrists and opticians who care for patients taking controlled drugs. It applies MOH's National Guidelines for the Safe Prescribing of Opioids (2021), MOH's 2008 guidance on benzodiazepines and other hypnotics, the restrictions on codeine cough mixtures, the collaborative prescribing guidelines and the SMC Handbook's standards on treating yourself and those close to you.

Controlled-drug concerns, especially long-term hypnotic and benzodiazepine prescribing, register failures and diversion, are a recurring source of disciplinary action, HSA and CNB involvement and patient harm. The course also covers the regulation 19 duty to notify suspected drug addicts, recognising diversion and impaired colleagues, the risk of undertreating pain, respectful communication across languages and with caregivers, and how to build and show safe practice through audit.

Questions about this course

What must a controlled-drug prescription contain in Singapore?

The patient's name and address, the prescriber's name, signature and practising address, the date, dosage form, name and strength of the preparation, dose, and total quantity in words and figures, with instalment directions where used. Dentists add 'for dental treatment only'. The prescription is valid for 30 days, and the prescriber's address must be in Singapore.

What are the rules for the controlled drugs register?

Anyone authorised to supply Second or Fourth Schedule drugs keeps a register in the prescribed form, with entries on the day of the transaction or the next day, in indelible ink. Entries must never be cancelled, obliterated or altered; corrections are made by dated marginal note or footnote. Registers are kept for three years from the last entry.

What is the regulation 19 duty?

A doctor who attends a person they consider, or have reasonable grounds to suspect, is a drug addict must notify the Director of Medical Services and the Director of the Central Narcotics Bureau within seven days, with the person's particulars and the grounds for suspicion. The course explains how to discuss this honestly with patients and refer them for treatment.

Does the course cover MOH's benzodiazepine and opioid guidance?

Yes. It applies MOH's 2008 guidance on benzodiazepines and other hypnotics (short courses, no concurrent use, referral beyond a cumulative eight weeks), the 2021 National Guidelines for the Safe Prescribing of Opioids, and the 2021 restrictions on codeine cough mixtures, including the supply limits.

Is this course relevant to nurses and pharmacists as well as doctors?

Yes. It covers the nurse in charge's responsibility for ward stock, safe administration of high-alert opioids, the pharmacist's legal and clinical check, collaborative prescribing limits, registers, stock counts, wastage, destruction and recognising diversion or an impaired colleague.

Can this course help after a concern about my prescribing?

It can support remediation by explaining the standards a board is likely to apply and showing you how to audit and change your practice.

How long is the course and how is it assessed?

About three hours, online and self-paced, with knowledge checks after each section and a final assessment of 20 scenario-based questions with an 80% pass mark. Whether it counts towards CME or CPE depends on your board or the relevant accreditor.
