Final answer:
Within seven days after authorizing an emergency telephone prescription, the prescriber must provide the pharmacist with a signed or valid electronic prescription for the controlled substance prescribed.
Step-by-step explanation:
When an emergency C2 (Schedule II controlled substance) prescription is issued over the phone, the pharmacist is allowed to dispense the medication for the immediate needs of the patient. However, to maintain proper documentation and comply with regulations, the prescriber must follow up within seven days by providing a signed or valid electronic prescription for the controlled substance.
This ensures accountability, proper record-keeping, and adherence to legal requirements surrounding controlled substances. Failing to provide the written prescription within the specified time frame may lead to regulatory violations.
In adherence to regulations, the prescriber has seven days to provide a written or electronic prescription for a Schedule II controlled substance after authorizing an emergency telephone prescription, ensuring proper documentation and compliance with legal requirements.
