Regulatory status

Where S1 to S4 sits on the scale

Depends on which listing applies

At the least restrictive, Schedule 1: sold by a pharmacist, no doctor's prescription needed. At the most restrictive, Schedule 4: prescription-only medicine. The listings below say which applies to which form, strength or pack size.

Schedule S1 to S4, 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; and, for animal treatment, a person practising a para-veterinary profession, on a veterinarian's written or verbal instruction.
