What is the maximum number of refills allowed for a Schedule III-IV prescription?

The correct answer reflects the regulations established by the Drug Enforcement Administration (DEA) regarding the refill limits for controlled substances classified as Schedule III and IV. These substances can be refilled up to five times within a six-month period. This provision is designed to balance patient access to necessary medications while ensuring that prescriptions for controlled substances are managed in a manner that prevents misuse and diversion.

Schedule III and IV controlled substances are recognized for their medical utility but also for their potential for abuse. Allowing up to five refills within a designated six-month timeframe enables patients who have a legitimate need for these medications to maintain their treatment without frequent trips to the pharmacy or having to secure a new prescription each time they need a refill.

While options like no refills or a lower number of refills might pertain to other schedules—such as Schedule I or certain prescriptions requiring more stringent controls—the established maximum for Schedule III and IV substances ensures a degree of accessibility while adhering to necessary regulatory oversight.
