What is the maximum number of refills allowed for C-III and C-IV prescriptions according to both state and federal laws?

The maximum number of refills allowed for Schedule III (C-III) and Schedule IV (C-IV) prescriptions is five. Both federal and Minnesota state laws align on this aspect of controlled substances. This means that a prescriber can authorize up to five refills within six months from the date the prescription is issued. Each refill should be filled in accordance with the prescribed directions, and after the five refill limit is reached, a new prescription must be written by the prescriber.

This limit applies specifically to C-III and C-IV medications, which are considered to have moderate potential for abuse relative to C-I and C-II substances, which have much stricter regulations. Understanding the refill limits of controlled substances is essential for pharmacists to ensure compliance with legal requirements and to maintain patient safety.
