How many times can a schedule III medication be refilled according to federal law when authorized by a prescriber?

Schedule III medications can be refilled a maximum of five times within a six-month period according to federal law, provided that the prescriber has authorized it. This regulation is in place to ensure that these substances, which have a lower potential for abuse compared to Schedule I and II drugs but still possess some risk, are used responsibly.

The six-month timeframe begins from the date the prescription was issued. After five refills are completed, a new prescription from the prescriber is required for additional medication. This guideline aims to control the distribution of these medications and reduce the risk of misuse while still allowing patients access to necessary treatment.

The other options suggest either fewer refills or a longer duration than is legally permitted, which misrepresents the federal regulations surrounding controlled substances. Understanding these limits is crucial for anyone working in pharmacy to ensure compliance and promote patient safety.
