What is the maximum number of refills allowed for a prescription for a controlled substance listed in Schedule III or IV?

The maximum number of refills allowed for a prescription for a controlled substance listed in Schedule III or IV is indeed five. This is established under federal regulation, which allows these controlled substances to be refilled up to five times within six months of the date the prescription was issued.

This provision is designed to provide patients with access to necessary medication while also maintaining a level of oversight to prevent misuse and abuse of controlled substances. The limit ensures that prescriptions are regularly reviewed, promoting patient safety and adherence to treatment plans. Additionally, once the five refills are exhausted or the six-month expiration period has lapsed, a new prescription must be obtained from the prescriber for any further refills or continuation of therapy.

The other options do not reflect the federal regulations governing controlled substances, as they all suggest lower or no refill limits, which are inconsistent with the allowances for Schedule III and IV medications.
