Friday Afternoon Extraction: Opioid Supply, Warfarin, and a Paper Script
Mr. Kowalski, 67, arrives at 4:45 p.m. on Friday with a vertically split lower right first molar, 3 mm mobility, and throbbing pain. He takes warfarin 5 mg daily (INR 2.8 last week), metoprolol, and has a documented penicillin allergy (rash). Dr. Nguyen plans extraction on Monday and wants to prescribe hydrocodone/acetaminophen 7.5/325 mg, one tablet every 6 hours as needed, #40, plus ibuprofen 600 mg every 6 hours for inflammation. The patient says he "doesn't do pharmacies" and asks for a paper script. The office has not yet queried the Connecticut Prescription Monitoring Program (PMP), and the dentist's DEA registration is current; the practice e-prescribes. The patient also reports taking occasional alprazolam prescribed by his primary care physician and drank two beers last night.
1. Is the proposed hydrocodone/acetaminophen prescription lawful in Connecticut? Calculate the day supply and explain the PMP obligation.
Read the worked answer
The quantity is likely unlawful for an initial acute-pain prescription. One tablet every 6 hours equals 4 tablets per day. A #40 supply is therefore a 10-day supply. Connecticut limits an initial opioid prescription for acute pain in an adult to a 7-day supply (and to a 5-day supply for a minor), subject to limited exceptions such as cancer, palliative care, or chronic pain management. A painful fractured tooth awaiting extraction does not obviously fit an exception. A compliant initial quantity would be no more than 28 tablets at this dosing.
Separately, Dr. Nguyen must query the Connecticut PMP before prescribing the opioid and document the review. The patient's alprazolam is especially important because concurrent opioid and benzodiazepine use increases respiratory depression risk. The PMP may also reveal other prescribers or early refills. The prescription should be reduced, the PMP results documented, and the patient counseled about sedation, alcohol, driving, storage, and naloxone.
2. Evaluate the ibuprofen recommendation and the acetaminophen load. What analgesic plan would you recommend?
Read the worked answer
Ibuprofen 600 mg every 6 hours is a poor choice for this patient. He takes warfarin with an INR of 2.8; NSAIDs increase the risk of gastrointestinal bleeding and can further elevate INR. The combination of warfarin, an NSAID, and possible alcohol use makes bleeding a serious concern. Avoid ibuprofen unless the anticoagulation prescriber is consulted and a clear plan for INR monitoring and gastroprotection is in place.
Acetaminophen is safer for anticoagulation, but the hydrocodone product already contains 325 mg per tablet. At 4 tablets per day, the patient would receive 1,300 mg of acetaminophen from the combination product. Any additional acetaminophen must be counted toward a total daily limit, generally no more than 3,000 mg per day for a patient with these risk factors. A sensible plan is a reduced opioid quantity, scheduled acetaminophen with a total daily count, and non-drug measures such as ice and soft diet. If an antibiotic is later indicated, avoid penicillins because of the documented rash.
3. Can Dr. Nguyen give the patient a paper prescription because he prefers one? What are the e-prescribing rules and exceptions?
Read the worked answer
Patient preference is not a recognized exception to Connecticut's electronic-prescribing requirement for controlled substances. Dr. Nguyen should transmit the prescription electronically to a pharmacy the patient will actually use, confirm the pharmacy's contact information, and document the transmission. A paper prescription is generally reserved for defined exceptions such as a temporary electronic system failure, certain technical limitations, or other narrow circumstances allowed by law.
If a true exception applies, the dentist should document the specific reason, the date and time, and the follow-up plan. "The patient doesn't like pharmacies" is not enough. The prescription should also be limited to the lawful day supply, and the patient should be told not to drink alcohol while taking the opioid or alprazolam. If the patient refuses electronic prescribing without a valid exception, the dentist should not simply default to a paper script; the safer course is to address the barrier, such as choosing a different pharmacy or arranging the prescription for Monday.
