What is the time limit within which the remaining quantity of a partially filled CII must be dispensed?

The correct time limit for dispensing the remaining quantity of a partially filled Schedule II (CII) prescription is 72 hours. According to federal and state regulations, when a pharmacist partially fills a CII prescription, they must dispense the remainder of the drug within this 72-hour window. If the remaining quantity is not dispensed within this time frame, the pharmacist must notify the prescribing practitioner, and the prescription would need to be rewritten if the patient still requires the medication.

This regulation is in place to ensure that patients have timely access to their medications while also addressing the potential for substance misuse associated with controlled substances. The 72-hour rule is designed to limit the amount of time that passes after an initial partial fill, encouraging both proper medication management and compliance with regulations governing the dispensing of controlled substances.
