Correct answer: E — Clarify the instalment direction with the prescriber before dispensing

Instalment prescriptions for controlled drugs must give clear directions that allow safe and lawful supply. Ambiguity about instalment amount, timing or supervision should be resolved with the prescriber. The pharmacist should not invent missing directions. Supplying the full quantity could create overdose and diversion risk.
