South Carolina Multistate Pharmacy Jurisprudence Examination (MPJE) Practice Exam

What is the limit on PRN refills for controlled substances?

1. 3 refills or 3 months

2. 5 refills or 6 months

3. Unlimited refills

4. 2 refills or 1 year

The correct answer is: 5 refills or 6 months

For controlled substances, federal and state regulations typically dictate the maximum number of refills and the time frame within which those refills can occur. The correct answer indicates that a prescription for a controlled substance can have a maximum of 5 refills, provided the prescription is filled within 6 months from the date it was issued. This limit ensures that there is a degree of oversight and monitoring in the prescribing and dispensing of controlled substances, which are classified as having a high potential for abuse. Allowing a maximum of 5 refills helps to mitigate the risk of misuse and ensures that patients are continually evaluated by their healthcare providers for the appropriateness of the treatment. Refills beyond this limit would typically require a new prescription. In contrast, some of the other options suggest fewer refills or longer time frames which do not align with established regulations for the management of controlled substances, emphasizing the importance of stringent controls in the handling of these medications.
