Rhode Island MPJE Practice Exam 2026 – Complete Study Guide

When a prescription for a Schedule II controlled substance is only partially filled, federal and state regulations allow the remainder to be filled within a specific time frame. In Rhode Island, if a CII prescription cannot be filled in full, the remaining portion must be filled within 72 hours from the date of the original prescription. This ensures that patients receive the necessary medication in a timely manner while also complying with regulatory guidelines concerning controlled substances.

Understanding the rationale for this timeframe is essential. It balances patient access to needed medications while still providing safeguards against potential misuse or diversion of controlled substances. If the remainder is not filled within this 72-hour period, the pharmacist must obtain a new prescription from the prescribing practitioner to dispense the remaining quantity. This regulation emphasizes the need for careful monitoring of controlled substance prescriptions and further enforces the accountability of both pharmacists and prescribers.
