What is the maximum validity period for a written prescription for a controlled substance in Schedule II?

The maximum validity period for a written prescription for a controlled substance in Schedule II is thirty days. This regulation is in place to ensure that the prescriptions for highly regulated substances, which have a high potential for abuse and dependence, are issued and filled within a specified timeframe to maintain patient safety and minimize the risk of misuse.

Once a Schedule II prescription is issued, it cannot be dispensed after the thirty-day period has expired, regardless of the remaining refills (if any were included). This rule is part of the effort to closely monitor the dispensing of medications that could lead to addiction or other serious health issues, ensuring that patients receive timely treatment without unnecessary delays or risks associated with long-standing prescriptions.

In contrast, other choices reflect longer periods that do not apply to Schedule II medications. For instance, medicines in other classifications, such as Schedule III or IV, may have longer validity periods, but these do not pertain to the stringent regulations surrounding Schedule II substances.
