2.1 Legislative requirements
☰ Table of contents


There are strict legal requirements around the prescription of drugs of addiction or controlled drugs, known as Schedule 8 (S8) medicines. The legislative requirements vary in each state and territory. Importantly, the legislative requirements for prescribing S8 drugs vary depending on the person’s dependence:

  • For drug dependent persons, S8 medications (and in some states and territories some benzodiazepines) cannot be prescribed without a permit or an appropriate approval from the relevant state or territory health department’s pharmaceutical services unit (PSU), via an authority/permit/approval, to patients who are known or suspected to be drug dependent.22
  • For non-drug-dependent persons, S8 medications cannot be prescribed for a period greater than 2 months without an appropriate approval in some states or territories.22

Before prescribing an S8 drug, GPs must take all reasonable steps to ensure a therapeutic need exists. Once a therapeutic need is established, GPs are required to comply with state- or territory-specific health legislation (refer to Appendix C.1 in the PDF version) and the fact sheets listed below and, where necessary, obtain an authority/permit from the relevant PSU. These authorities are distinct from, and in addition to, any authority under the PBS for scripts.23

When a PBS or Repatriation Pharmaceutical Benefits Scheme (RPBS) authority application is for an S8 medicine (other than dexamphetamine sulphate or methylphenidate), the following guidelines apply:24

  • the maximum quantity is generally for 1 month’s supply (eg 1 week’s therapy with three repeats)
  • where supply for a longer period is warranted, quantities are usually for up to 3 months’ therapy
  • telephone approvals are limited to 1 month’s supply.

Prescribers need to state the interval of repeat where repeats are called for and ensure state or territory health authorities are notified about ongoing treatment. Review by a second doctor is required for PBS prescription of an opioid beyond 12 months.24

Inappropriate S8 prescribing may result in criminal prosecution, financial penalties, the loss of a doctor’s authority to prescribe S8 drugs or disciplinary action.22

Refer to the appropriate state and territory legislation and contacts at Appendix C.2 in the PDF version.
