Regulatory status
Where S4 sits on the scale
Prescription-only medicine.
Schedule 4 covers most ordinary prescription medicines. You need a prescription from an authorised prescriber, such as a doctor or dentist, and a pharmacist dispenses it. 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 S4, matched to the Consolidated Schedules by ingredient, confidence high.
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.
