Refills, Transfers and Partial Fills by Schedule

Three questions arise at the counter after a prescription has been accepted as valid: may it be refilled, may it be moved, and may part of it be dispensed now. The answers diverge sharply by schedule, and each carries a deadline that runs from a different event. Getting the starting point of the clock wrong is the most common source of error.

Where the refill line falls

Refilling a Schedule II prescription is prohibited. Which limits apply to a given drug turns on where it sits among the five schedules. The rule states it in a single sentence with no exceptions, and a pharmacy that dispenses a second quantity against the same prescription has dispensed without a prescription.

What is permitted instead is a series of separate prescriptions. A practitioner may issue multiple prescriptions authorizing a patient to receive a total of up to a ninety-day supply, provided each is issued for a legitimate medical purpose in the usual course of practice, each after the first carries written instructions showing the earliest date a pharmacy may fill it, the practitioner concludes that the arrangement creates no undue risk of diversion or abuse, and state law permits it. None of these is a refill; each is a prescription in its own right, and the practitioner is under no obligation to use the mechanism.

Schedules III and IV run on two limits at once. A prescription may not be filled or refilled more than six months after the date it was issued, and may not be refilled more than five times. Whichever limit is reached first ends the prescription. Additional quantities require a new prescription, not an oral extension of the old one.

Oral authorization and what the record must show

A prescriber may authorize additional refills of a Schedule III or IV prescription orally, but only within the existing limits. The total authorized, including the original fill, may not exceed five refills or extend beyond six months from the issue date of the original prescription, and each additional refill must be for a quantity equal to or less than the quantity authorized for the initial filling.

The pharmacist taking the authorization records the date, the quantity of the refill, the number of additional refills authorized, and initials the record showing who received the authorization. If a pharmacist merely initials and dates the back of the prescription without more, the full face amount is deemed to have been dispensed.

For each refill the pharmacy must be able to retrieve, by prescription number, the drug name and dosage form, the date filled, the quantity dispensed, the dispensing pharmacist's initials and the total number of refills for that prescription. Those entries feed directly into the records that have to reconcile at an inspection.

Partial fills and the three clocks

Schedule II partial filling operates under three separate regimes, distinguished by why the partial fill happened.

Where the pharmacist cannot supply the full quantity, the shortfall may be dispensed later, but the remaining portion must be filled within seventy-two hours of the first partial fill. If it cannot be, the pharmacist must notify the prescriber, and no further quantity may be supplied without a new prescription.

Where the partial fill is requested by the prescriber or by the patient, a different clock applies. The remaining portions must be filled no later than thirty days after the date the prescription was written, except that an emergency oral prescription still runs on the seventy-two hour rule. The prescriber requesting a partial fill must specify the quantity for each portion on the face of the prescription or in the electronic record.

Where the patient is in a long term care facility or has a documented terminal illness, the prescription may be filled in partial quantities down to individual dosage units, and remains valid for up to sixty days from the issue date unless the medication is discontinued sooner. The pharmacist must record on the prescription whether the patient is terminally ill or a long term care facility patient; a partial fill without that notation is deemed to violate the statute.

Moving a prescription to another pharmacy

Transfer of original prescription information for refill purposes is permitted for Schedules III, IV and V on a one-time basis only. Pharmacies that electronically share a real-time, online database may transfer up to the maximum refills the prescriber authorized.

The mechanics are prescriptive. The transfer must be communicated directly between two licensed pharmacists. The transferring pharmacist writes the word void on the face of the invalidated prescription, or adds the equivalent information to the electronic record, and records the receiving pharmacy's name, address and registration number, the receiving pharmacist's name, the transfer date and the transferring pharmacist's name.

The receiving pharmacist writes transfer on the face of the new prescription and records the original issue date, the original number of refills authorized, the date of original dispensing, the number of valid refills remaining with the dates and locations of previous refills, and the identifying details of both the transferring pharmacy and the pharmacy that originally filled it. Both the original and the transferred prescription are kept for two years from the date of the last refill.

Transfer is only available where state law permits it, which is a real constraint rather than a formality. Where a pharmacy is uncertain, declining to transfer and asking the prescriber to issue a fresh prescription is consistent with the corresponding responsibility that attaches to dispensing, and it avoids creating a second live prescription for the same course of treatment. Electronic transfers add their own layer, since the receiving system must meet the standards described under electronic prescribing of controlled substances.
