Where S2 sits on the scale
A pharmacist can sell it directly, without a prescription.
Schedule 2 medicines sit behind the pharmacy counter. A pharmacist can decide to sell one of these directly, using their own professional judgement, without a doctor's prescription. It can also be dispensed against a prescription like the higher tiers, in which case the usual repeat limits apply. A child under 12 may only be sold a Schedule 2 substance on a prescription, or on a written order that names the purpose and carries a signature the seller recognises. Even though it cannot be advertised to the public in the ordinary sense, its price, name, pack size and strength can still be told to the public, as long as nothing links it to what it treats.
Schedule S2, read from the product's PI-PIL leaflet.
The Consolidated Schedules list this ingredient up to S3; the leaflet's S2 applies to this product.
Who may supply: Only a pharmacist, pharmacist intern or supervised pharmacist's assistant may sell it without a prescription. It may otherwise be dispensed by a pharmacist 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); and, for animal treatment, a person practising a para-veterinary profession, on a veterinarian's written or verbal instruction.
