Regulatory status
Where S3 sits on the scale
Needs a doctor's prescription, dispensed by a pharmacist.
Schedule 3 medicines can only be sold on a prescription from an authorised prescriber, such as a doctor or dentist. A pharmacist dispenses the medicine once they have the written prescription, or a verbal instruction from a prescriber they know. 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 S3, matched to the Consolidated Schedules by ingredient, confidence medium.
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.
