. Under the Act, a prescription for these drugs need to show full details including the form and strength of the preparation, with the total quantity written out in both words and figures. It is an offence for a doctor to issue an incomplete prescription or for a pharmacist to dispense a controlled drug unless all the required details are given.

It is the prescriber's responsibility to minimize the risk of dependence or misuse by ensuring that such drugs are not started for a particular patient without good cause, that the dose is not increased to the point where dependency is more likely, and to avoid being an unwitting source of supply for addicts. The quantities of controlled drugs prescribed should match the likely needs of the patients until the next clinical review and prescription forms should be secured against theft.

Requirements for safe custody in pharmacies apply to all Sch 2 Controlled Drugs except quinalbarbitone.

The safe custody requirements ensures that pharmacists and doctors holding stock of controlled drugs must store them in securely fixed double-locked steel safety cabinets and maintain a written register, which must be bound and contain separate entries for each drug and must be written in ink with no use of correction fluid. Disposal of expired stock must be witnessed by a designated inspector (either a police officer or a suitably qualified official).
