What is a requirement for refilling prescriptions of controlled substances?

Controlled substances are categorized into schedules, each with specific regulations regarding prescriptions and refills. Schedule II drugs are considered to have a high potential for abuse and thus have stringent rules governing their prescription. One of the primary requirements for Schedule II substances is that they cannot be refilled. Instead, a new prescription must be issued for each fill. This regulation aims to limit access and control the distribution of these drugs to prevent misuse and ensure patient safety.

In contrast, other schedules, like Schedule III or IV substances, may have allowances for refills up to a limit, but this does not apply to Schedule II drugs. Understanding this distinction is crucial for anyone involved in the prescription and dispensing of medications, as adherence to these regulations is mandatory to comply with federal and state laws.
