What must a pharmacist write on the prescription face during a physical controlled substance transfer?

When a pharmacist is involved in a controlled substance transfer, it is essential that they indicate clearly that the original prescription is no longer valid for new dispensing. Writing "VOID" on the face of the prescription serves this purpose effectively. This notation clearly communicates to any subsequent pharmacists or personnel that the prescription should not be filled again, thereby helping to prevent potential misuse or confusion regarding the status of the prescription.

In the context of Illinois pharmacy law, marking a prescription as "VOID" provides proper documentation and ensures compliance with regulatory requirements related to the handling of controlled substances. This practice not only protects the integrity of the medication dispensing process but also upholds the safety and legal responsibilities of pharmacy practice.

The other options, while they might suggest some form of invalidation, do not have the same legal recognition or clarity as "VOID." "REPRINT" could imply that the prescription has been reproduced, while "CANCELLED" might create ambiguity regarding whether the prescription can be referred back to in the future. "COMPLETE" does not accurately reflect the refilled status of the prescription and could lead to confusion regarding its validity. Therefore, "VOID" is the appropriate and most effective term to be utilized.
