Early Opioid Fill and Maine's Acute-Pain Limit
A 34-year-old woman presents to a community pharmacy in Portland, Maine, on a Tuesday afternoon with a paper prescription for oxycodone 5 mg, #40, one tablet every 6 hours as needed for pain, written four days earlier by a Maine-licensed dentist after a wisdom-tooth extraction. The prescription does not state 'acute pain' or a diagnosis. The pharmacist queries the Maine Prescription Monitoring Program and sees a 7-day supply of hydrocodone/acetaminophen filled 11 days ago by a different prescriber, plus an active buprenorphine/naloxone prescription from a substance-use disorder clinic. The patient says the dentist told her to fill it whenever and that she only took two tablets of the earlier opioid. The pharmacy has 60 tablets in stock; the patient asks for a partial fill of 20 because she cannot pay for all 40 today.
1. Can the pharmacist legally fill this Schedule II prescription as written? Analyze the federal and Maine issues and list what the pharmacist must verify before dispensing.

Start with federal validity: a Schedule II prescription must be issued for a legitimate medical purpose by a practitioner acting in the usual course of professional practice; it must contain the patient name, drug, strength, quantity, directions, date, and prescriber signature, and it may not be refilled. The pharmacist has a corresponding-responsibility duty to resolve red flags, not merely process the document.
Maine adds a separate limit: for acute pain, an opioid prescription may not exceed a 7-day supply unless a statutory exception applies and is documented. This prescription is written q6h PRN, which is up to 4 tablets per day; #40 is therefore up to a 10-day supply at maximum use, so it facially exceeds the 7-day limit. The missing diagnosis is another red flag.
Before dispensing, the pharmacist should: (1) query the PDMP, which was done; (2) contact the dentist to confirm the indication, acute versus chronic status, and any exception; (3) disclose the active buprenorphine/naloxone so the prescriber can assess interaction risk; and (4) determine whether the quantity should be reduced to a 7-day supply. If the prescriber cannot substantiate an exception, the pharmacist should not fill.
2. The patient requests a partial fill of 20 tablets. Explain the federal partial-fill rules that apply, including the deadline for the remaining 20 tablets and what the pharmacist must record.

Because the pharmacy has 60 tablets, this is not an insufficient-stock partial fill. The patient's request is a partial fill at the patient's request, governed by 21 CFR 1306.13(b). The pharmacist may dispense 20 tablets and must record the date of each partial fill, the quantity dispensed, and the dispensing pharmacist. The remaining 20 tablets may be dispensed only within 30 days of the date the prescription was written. The prescription was written four days ago, so the balance must be dispensed by day 30 from that date; after that, the pharmacist may not dispense the balance without a new prescription. Each dispensing event should be reported to the Maine PDMP as required.
If the pharmacist instead lacked stock, the 72-hour rule would apply, but that is not the situation here. The pharmacist should also confirm that the partial quantity does not evade the 7-day acute-pain limit. A 20-tablet partial at up to 4 per day is a 5-day supply, but the original 40-tablet prescription still needs prescriber clarification before any dispensing.
3. Assume the pharmacist contacts the dentist, who says the patient did not disclose buprenorphine and that the opioid is for acute pain. What should the pharmacist document, and what counseling should be provided?

Document the call in the pharmacy record: date and time, prescriber name and phone number, pharmacist name, the PDMP findings, the buprenorphine disclosure, the prescriber's confirmation of acute pain and any exception, the final quantity authorized, and the dispensing decision. If the prescriber confirms acute pain but does not reduce the quantity, ask for a revised prescription for no more than a 7-day supply; a verbal change to a Schedule II prescription is generally not permitted except in limited emergency situations, so a new written prescription may be required.
Counsel the patient on sedation, respiratory depression, avoiding alcohol and benzodiazepines, secure storage, disposal, and naloxone availability. Offer naloxone because of the buprenorphine history. Tell her not to take the opioid and buprenorphine together without direction from the buprenorphine prescriber, and document the counseling. If the prescriber cannot confirm a lawful basis or an exception, document the refusal and return the prescription.
