Correct answer: A — The prescription has expired for controlled drug dispensing and needs prescriber review

Phenobarbital is a controlled drug, and prescriptions for Schedule 2, 3 and 4 CDs are generally valid for 28 days from the appropriate date. A 35-day-old prescription should not be dispensed as written. The patient's epilepsy is clinically important, so urgent prescriber contact or lawful emergency supply considerations may be needed. The duration of previous therapy does not extend prescription validity.
