What is the maximum number of times a Schedule IV drug can be refilled within six months?

Schedule IV drugs are controlled substances that have a lower potential for abuse relative to Schedule I, II, and III drugs. According to the Drug Enforcement Administration (DEA) regulations, Schedule IV drugs can be refilled up to five times within a six-month period after the prescription is issued. This provision allows for greater flexibility in medication management for patients who require consistent use of these medications while also ensuring that there is adequate oversight on the amount of medication that can be dispensed.

This regulation reflects a balance between maintaining access to necessary medications for patients, such as those for anxiety or sleep disorders, while also monitoring the potential for misuse or dependence on these drugs. Therefore, the correct answer indicates that patients can receive refills on their Schedule IV prescriptions five times within the designated six months.
