The Last Patient of the Day

Patient: 37-year-old male, not a patient of record

Chief Complaint: “I'm in agony. Oxycodone is the only thing that touches it. I just need a prescription.”

Background: Walked in at closing time. Says he is from out of town, cannot name a regular dentist, declines to give a pharmacy. Becomes insistent when questioned.

Medications: “Nothing regular.”

Vital Signs: BP 132/84 mmHg · HR 84 bpm · RR 16 · T 98.6°F

Findings: Examination reveals no swelling, no caries into dentin, no periodontal defect, no percussion tenderness and no radiographic pathology corresponding to the area he indicates.

Question 1

What is the most appropriate management?

  1. Call 911
  2. Prescribe ibuprofen with acetaminophen and arrange follow-up
  3. Provide the oxycodone prescription he has requested
  4. Refuse care and ask him to leave
Show answer and explanation

Correct answer: B. Prescribe ibuprofen with acetaminophen and arrange follow-up

  • A. There is no medical emergency. Nothing about this presentation warrants emergency services.
  • B. CORRECT. The combination of an NSAID with acetaminophen provides analgesia EQUAL OR SUPERIOR to opioid combinations for acute dental pain, with a far better safety profile — a large body of evidence supports ibuprofen 400–600 mg with acetaminophen 500–1000 mg as first-line. Prescribing it treats any genuine pain, addresses the demand appropriately, and does not require you to decide whether the patient is being truthful.
  • C. There is no clinical finding to justify any analgesic prescription beyond first-line, let alone a Schedule II opioid, in a patient not of record at the end of the day who is specifying the drug by name.
  • D. Turning away a patient who reports severe pain without examining or offering appropriate treatment is not defensible. You have examined him; the correct response is to treat appropriately, not to refuse engagement.

Note: The classic drug-seeking pattern: unfamiliar patient, end of day or weekend, pain out of proportion to findings, a named drug, a claimed allergy to alternatives, and reluctance to give a pharmacy or regular provider. Check the state Prescription Drug Monitoring Program before writing any controlled substance.

Question 2

Under the DEA schedules, hydrocodone and oxycodone are classified as:

  1. Schedule II
  2. Schedule I
  3. Schedule III
  4. Schedule IV
Show answer and explanation

Correct answer: A. Schedule II

  • A. CORRECT. Both oxycodone and hydrocodone — including hydrocodone-acetaminophen combinations, which were rescheduled from III to II in 2014 — are SCHEDULE II. Schedule II drugs have accepted medical use but high abuse potential with severe psychological or physical dependence. Practically, this means NO refills are permitted and a new prescription is required each time.
  • B. Schedule I drugs have NO accepted medical use and cannot be prescribed at all: heroin, LSD, and (federally) cannabis.
  • C. Schedule III includes codeine combinations (Tylenol with Codeine), buprenorphine and ketamine. Up to five refills within six months are allowed.
  • D. Schedule IV includes the benzodiazepines — diazepam, midazolam, triazepam, alprazolam — and tramadol. Also up to five refills in six months.

Note: Dental-relevant memory aid: II = oxycodone, hydrocodone, morphine, meperidine, amphetamine. III = codeine combinations. IV = benzodiazepines and tramadol. V = low-dose codeine cough preparations.

Question 3

A different patient asks for hydrocodone, saying it is the only drug that works for his chronic facial pain. He has been treated in the practice for years and there is no acute dental cause. What is the best action?

  1. Tell him nothing further can be done
  2. Refer him to his physician for management of the chronic pain
  3. Prescribe a small quantity of hydrocodone given the established relationship
  4. Prescribe a long course of antibiotics in case of occult infection
Show answer and explanation

Correct answer: B. Refer him to his physician for management of the chronic pain

  • A. Saying nothing can be done abandons him. Something CAN be done — the referral, plus explanation of what has been excluded and why.
  • B. CORRECT. Chronic pain with no identifiable dental cause is OUTSIDE the scope of dental practice. Chronic opioid therapy requires longitudinal assessment, monitoring and a single prescribing clinician — it is not something to be initiated or continued from a dental chair. Referring to his physician, with a clear note documenting that dental causes have been excluded, is both the correct clinical step and the correct professional one.
  • C. A long-standing relationship does not create an indication. Prescribing an opioid without a dental diagnosis is inappropriate regardless of how well you know the patient, and fragmented prescribing across providers is precisely how patients are harmed.
  • D. Antibiotics for pain without evidence of infection is inappropriate prescribing and contributes to resistance.

Note: Exclude the dental causes properly first: cracked tooth syndrome, atypical odontalgia, myofascial pain, trigeminal neuralgia and sinus disease can all masquerade as toothache. Then refer.
