What must a pharmacist do with a CII prescription?

When a pharmacist fills a Schedule II (CII) prescription, it is essential for them to write the date filled and sign the prescription. This requirement is in place to maintain accurate records and ensure proper tracking of controlled substances, which are strictly regulated due to their potential for abuse and dependence.

By documenting the date of filling, the pharmacist provides crucial information on when the medication was dispensed, which is important for both patient care and regulatory compliance. The pharmacist's signature further authenticates the filling of the prescription, indicating that they have verified the prescription and are legally responsible for that transaction. This process is vital in preventing misuse and ensuring accountability within the pharmacy setting.

The other options might seem relevant but do not encompass the specific legal requirements a pharmacist must follow when handling a CII prescription. Storing the prescription in a locked cabinet is generally good practice for security, but it is not specifically mandated as a requirement for filling the prescription. Initialing the prescription does not fulfill the complete requirement, as the accurate recording of the date filled is also mandatory. Faxing it to a central pharmacy does not apply unless specific conditions are met, which typically do not replace the need for proper documentation on the original prescription itself.
