What is the maximum supply that can be filled for a Schedule II or III drug upon any single filling?

For Schedule II and III drugs, the maximum supply that can be filled upon any single prescription is typically 30 days' worth of medication. This aligns with federal and state regulations designed to ensure safe prescribing practices and monitor control substances.

The reasoning behind the 30-day limit is primarily to prevent misuse and overprescribing of controlled substances, which can contribute to addiction and other public health issues. Allowing a longer supply, such as 60 days or 90 days, may increase the risk of diversion or misuse, while shorter durations support more frequent physician follow-up and assessment of the patient's needs and response to therapy.

The options of 60 days, 90 days, and 5 years exceed the standard maximum fill limits for Schedule II and III medications, thus making them inappropriate. Ensuring adherence to the 30-day limitation is crucial for effective management of patients who require medications classified under these schedules.
