5.—(1) A dispensing doctor (D) must only provide for a patient any Scheduled drug if—
(a)it is ordered as specified in sub-paragraph (2) or (4); or
(b)in the case of a drug specified in Schedule 2 to the Prescription of Drugs Regulations (drugs, medicines and other substances that may be ordered only in certain circumstances), it is ordered in the circumstances prescribed in that Schedule.
(2) A Scheduled drug that is a drug with an appropriate non-proprietary name may be provided in response to an order on a prescription form or repeatable prescription for a drug (“the prescribed drug”) that is not a Scheduled drug but which has the same non-proprietary name as the Scheduled drug if—
(a)the prescribed drug is ordered by that non-proprietary name or by its formula; and
(b)the prescribed drug has the same specification as the Scheduled drug (so the Scheduled drug may be dispensed generically).
(3) If a Scheduled drug is a combination of more than one drug, it can only be ordered as specified in sub-paragraph (2) if the combination has an appropriate non-proprietary name, whether or not the drugs in the combination each have such names.
(4) Nothing in this Schedule prevents D providing, otherwise than under pharmaceutical services, a Scheduled drug or a restricted availability appliance for a patient.
