This actually came up in the Notice of Proposed Rulemaking about electronic prescriptions for controlled substances:
2010 - Interim Final Rule With Request for Comment: Electronic Prescriptions for Controlled Substances (Cont'd)
5. Transfers
In the NPRM, DEA confirmed existing regulations regarding the transfer of prescriptions for Schedule III, IV, and V controlled substances.
Specifically, under Sec. 1306.25(a) a pharmacy is allowed to transfer an original unfilled electronic prescription to another pharmacy if the first pharmacy is unable to or chooses not to fill the prescription. Further, a pharmacy is also allowed to transfer an electronic prescription for a Schedule III, IV, or V controlled substance with remaining refills to another pharmacy for filling provided the transfer is communicated between two licensed pharmacists. The pharmacy transferring the prescription would have to void the remaining refills in its records and note in its records to which pharmacy the prescription was transferred. The notations may occur electronically. The pharmacy receiving the transferred prescription would have to note from whom the prescription was received and the number of remaining refills.
Comments. One commenter, a large pharmacy, believed that while the NPRM addressed the transfer of prescription refill information for Schedule III, IV, and V controlled substance prescriptions,
it did not address the transfer of original prescriptions that have not been filled.
DEA Response. As DEA explained in the NPRM, the existing requirements for transfers of Schedule III, IV, and V controlled substances prescriptions remain unchanged. DEA currently permits the transfer of original prescription information for a prescription in Schedules III, IV, and V on a one-time basis. This allowance does not change. DEA wishes to emphasize that the only changes made to Sec. 1306.25 as part of the NPRM were to revise the text to include separate requirements for transfers of electronic prescriptions. These revisions were needed because an electronic prescription could be transferred without a telephone call between pharmacists. Consequently, the transferring pharmacist must provide, with the electronic transfer, the information that the recipient transcribes when accepting an oral transfer.
