What schedule of controlled substances requires a prescription that cannot be refilled?

Schedule II controlled substances are classified as drugs with a high potential for abuse that may lead to severe psychological or physical dependence. Due to the risks associated with these substances, they are governed by stringent regulations.

One major regulation dictates that prescriptions for Schedule II substances cannot be refilled. This requirement is in place to ensure close monitoring of the prescribing and dispensing of these drugs, considering their potential for misuse and addiction. A new prescription must be issued each time a patient needs a refill, necessitating a new consultation with the healthcare provider. This process helps maintain a higher level of oversight and accountability in their use.

In contrast, Schedule III and Schedule IV substances allow for refills under certain conditions, which permits pharmacies to refill these prescriptions up to a limit set by law. Schedule I substances are not available for prescription at all, as they are deemed illegal and lacking any accepted medical use.
