What is the timeframe in which a remainder of a partially filled C-II prescription must be dispensed?

The correct timeframe for dispensing the remainder of a partially filled Schedule II (C-II) prescription is 72 hours from the date of the first partial fill. This regulation is in place to ensure that patients receive their prescribed medication in a timely manner while maintaining strict control over potentially abused substances.

A partially filled C-II prescription allows for the dispensing of a portion of the medication initially, and the remainder can be dispensed later if needed. However, the 72-hour limit ensures that the patient either receives the full prescription promptly or, if they do not return for the rest, the prescription is not left open indefinitely, which could lead to misuse or diversion of controlled substances.

Understanding this timeframe is essential for pharmacy practice and helps maintain compliance with both federal and state regulations concerning controlled substances. Familiarity with the rules surrounding partially filled C-II prescriptions is crucial for pharmacists and helps ensure responsible dispensing of medications.
