What is the maximum validity period for a C-II prescription from the day it is written?

A C-II prescription is valid for a maximum of 60 days from the date it is written. This is governed by federal regulations, which stipulate that a prescription for a controlled substance in Schedule II cannot be filled or refilled beyond this time frame. This regulation is designed to ensure patient safety and minimize the risk of misuse or diversion of highly potent substances.

While some other classes of prescriptions may have longer validity periods, C-II prescriptions are treated with heightened scrutiny due to their potential for abuse and addiction. Therefore, understanding this 60-day limit is essential for compliance with both state and federal pharmacy laws.
