Prescription Processing, Dispensing, and Prescribing Authority
What makes a prescription valid
A prescription must identify the patient, the drug (name, strength, dosage form), quantity, directions for use, date of issue, and the prescriber (name, address, and DEA number when the drug is controlled). The prescriber must have authority: Schedule II privileges where applicable, an active DEA registration, and - for Virginia mid-level practitioners - a practice arrangement that permits the schedule written.
Refills, expiration, and transfers
Federal ceilings: Schedule II may not be refilled; Schedule III–V may be refilled up to five times within six months of issue. Virginia imposes its own fill-by and refill limits, so check the regulation rather than borrowing another state's number. Schedule II may be partially filled at the patient's or prescriber's request, with the remainder supplied within 30 days (60 days for long-term care or terminally ill patients). Emergency oral Schedule II orders require a written prescription within seven days. Transfers must be documented, and the rules on transferring electronic Schedule II prescriptions should be verified against current federal and Virginia positions.
Traps
- Assuming any prescriber may write any schedule.
- Missing a missing or invalid DEA number (check digit).
- Filling a Schedule II prescription that authorizes refills.
Worked example
Rule of thumb: count the elements, check the authority, check the clock. A Schedule IV prescription written seven months ago with two refills remaining fails on the clock - it is beyond the six-month federal refill window regardless of refills left - and a shorter Virginia limit would control if one applies.
