3 Refills, Prescription Transfers, and Communication
Learn the federal refill limits, documentation rules, and distinct transfer workflows for controlled-substance prescriptions, including where state law also applies.
limits by schedule
Federal rules distinguish refilling a prescription from transferring it between pharmacies. A must be authorized, and a transfer must follow the workflow that applies to the prescription’s schedule and status. State law may impose stricter requirements, so pharmacists must check both federal and applicable state rules.
How limits differ
A prescription cannot be refilled. When federal and state requirements are met, a practitioner may instead issue separate prescriptions totaling up to a 90-day supply, with instructions specifying when later prescriptions may be filled. These are separate prescriptions, not refills.
For , a prescription may be refilled only as authorized, no more than five times and within six months of its issue date. Any additional quantity requires a new prescription. A practitioner may authorize additional refills orally, but the total must still remain within both limits; the pharmacist must document the authorization and required details.
For , federal regulations do not set the same numerical limit specified for . Refills still require authorization and must be issued for a legitimate medical purpose in the usual course of professional practice. State law may set limits.
records
A record must be maintained in the prescription record or in another uniformly maintained, readily retrievable record. For Schedule III and IV refills, the record must allow retrieval of the fill date, quantity dispensed, dispensing pharmacist’s initials or identification, and total refills dispensed.
transfers for Schedules III–V
Prescription information for a Schedule III, IV, or V controlled substance may generally be transferred to another pharmacy once for dispensing. The transfer must be communicated directly between two licensed pharmacists, and state law must permit it. Pharmacies that share a real-time, online database may transfer refills up to the amount permitted by law and the prescriber’s authorization.
For a paper prescription, the transferring pharmacist marks the original “VOID” and records the receiving pharmacy’s name, address, and DEA registration number; the receiving pharmacist’s name; the transfer date; and the transferring pharmacist’s name. The receiving pharmacist marks the transferred prescription “transfer” and documents the original issue and dispensing dates, originally authorized refills, valid refills remaining, previous dates and locations, and the transferring pharmacy’s identifying information and prescription number. Required originating-pharmacy information must also be recorded.
For an electronic prescription, the pharmacists document the transfer in the electronic records and transmit the required dispensing and history, pharmacy information, and pharmacist identities. The receiving pharmacist creates an electronic record containing the transferred information. The original and transferred records must be retained for two years from the last .
Initial-fill transfers of electronic prescriptions
A separate federal workflow permits a –V electronic controlled-substance prescription that has not yet been initially dispensed to be transferred between retail pharmacies once, at the patient’s request. This is distinct from the -transfer rule for Schedules III–V.
The prescription must remain in electronic form, without alteration, and pass directly between two licensed pharmacists. It cannot be converted to paper or fax for transmission. The transferring pharmacist records that the prescription was transferred, the receiving pharmacy and pharmacist, and the transfer date. The receiving pharmacist records that it is a transfer and documents the sending pharmacy and pharmacist and the date. Both pharmacies retain the electronic transfer records for two years from the transfer date. This workflow is available only where state and other applicable law allow it.
Federal rules do not authorize using this electronic initial-fill procedure to transfer an unfilled paper, faxed, or oral prescription to another pharmacy. Applicable law and pharmacy policy govern how to resolve an unfilled non-electronic prescription; this may require contacting the prescriber for an appropriate new prescription.
Checks before dispensing
Before acting on a or transfer request, confirm the prescription’s schedule, whether it has already been initially dispensed, the authorized refills remaining and applicable time limits, applicable state law, and the identity and authority of the communicating pharmacists. Record the communication and all required prescription details in the appropriate system.
A transfer does not extend a prescription’s validity, create additional refills, or remove the pharmacist’s responsibility to ensure that the prescription is valid and dispensed for a legitimate medical purpose.
