Final answer:
A prescriber must provide a pharmacist with a written prescription for an emergency Schedule II controlled substance within seven days of the oral authorization, as required by the Controlled Substances Act.
Step-by-step explanation:
In response to the question regarding emergency prescriptions of Schedule II controlled substances, a prescriber is required to provide a written prescription to the pharmacist within seven days after the emergency oral authorization. Failure to provide this written prescription within the seven-day period may result in a violation of the Controlled Substances Act.
Under the Controlled Substances Act (CSA), in an emergency situation, a prescriber may call in an emergency prescription for a Schedule II drug to a pharmacy. However, the prescriber must follow this oral authorization with a written prescription sent to the pharmacist. The written prescription must be delivered within a specified timeframe. This protocol is outlined by the Drug Enforcement Administration (DEA), which specifies that the prescriber has seven days to provide the hard copy of the prescription. This hard copy must contain all the proper information required for a Schedule II prescription, including a written and signed document by the prescriber. If the written prescription is not provided within the seven-day period, the pharmacist is instructed to notify the DEA.
