Regulatory status

Where S2 to S5 sits on the scale

Depends on which listing applies

At the least restrictive, Schedule 2: a pharmacist can sell it directly, without a prescription. At the most restrictive, Schedule 5: prescription-only, with tighter controls on repeats. The listings below say which applies to which form, strength or pack size.

Schedule S2 to S5, as the Consolidated Schedules list it.

Who may supply: A pharmacist dispensing against a written or verbal prescription from an authorised prescriber; a veterinarian, who may also prescribe, compound or dispense it directly; a medical practitioner or dentist, who may prescribe it and may compound or dispense it directly only if licensed under section 22C(1)(a); manufacturers and wholesalers may supply people who may lawfully possess it.
