What is the maximum allowable supply of a Schedule III prescription that can be filled at one time?

The maximum allowable supply for a Schedule III prescription that can be filled at one time is a 30-day supply. This regulation is established to ensure safety and control over substances that have a potential for abuse. Schedule III drugs, although considered to have a lower potential for abuse than Schedule I and II drugs, still require careful management.

A 30-day limit helps prevent overuse or misuse of these medications by limiting the amount that can be dispensed in a single fill. This not only aids in monitoring ongoing patient use but also allows healthcare providers to reevaluate the patient's need for the medication at regular intervals, enhancing patient management and oversight.

While the choices included larger supply options like 60, 90, or 120 days, they exceed the maximum set standards for Schedule III prescriptions. Therefore, the 30-day supply reflects appropriate regulatory measures in pharmacy practice regarding controlled substances.
