Correct answer: CSupply must follow the prescriber's instalment directions and endorsed wording

Controlled drug instalment prescriptions must be supplied in accordance with the prescriber's directions and any permitted wording for non-collection days. The pharmacist has limited discretion and should clarify if the directions do not cover closure. Omitting a dose or combining instalments without authority may be unsafe and unlawful. Clear endorsement and communication are essential.
