Early Refill, Negative Urine Screen, and Cocaine
45-year-old man with chronic low back pain on oxycodone 15 mg three times daily (MEDD 67.5 mg) presents 10 days early for refill, saying his pills were stolen. Urine drug screen is negative for oxycodone and positive for cocaine. He becomes tearful and says he will 'go crazy' without them. He has no history of overdose, but drinks two beers nightly and smokes. PDMP shows three prescribers and two pharmacies in 12 months.
1. What is your immediate response to the early refill request, and how do you assess risk?
Read the worked answer
I would not refill the prescription at this visit and would not accuse him of diversion. I would say that the urine result and the early refill are concerning and that I want to understand what is happening. I would confirm the cocaine result and the absence of oxycodone with liquid chromatography–tandem mass spectrometry, because immunoassays can cross-react; I would also ask about whether he has been taking the oxycodone at all, sharing or selling it, or using other substances. I would assess for opioid use disorder using DSM-5 criteria, check for withdrawal, and review the PDMP for overlapping prescriptions and pharmacies. I would screen for depression, suicidality, and social stressors. Because he is on a moderate dose (MEDD 67.5 mg) and has cocaine use, his overdose risk is elevated; I would prescribe naloxone and discuss it. I would not abruptly stop opioids without a plan, because withdrawal and untreated pain could push him to illicit sources.
2. What are the treatment and prescribing options, and how do you avoid abandonment?

The options depend on whether he meets criteria for opioid use disorder. If he does, buprenorphine is first-line and can treat both OUD and pain; I would offer it and arrange induction, rather than simply tapering. If he does not meet criteria but is misusing or diverting, I would transition to a structured, single-prescriber agreement with pill counts, frequent visits, and a slow taper, while offering addiction counseling and mental health care. Continuing full-dose oxycodone without monitoring is not safe given the negative UDS and cocaine use. I would not discharge him from the practice solely for a positive cocaine test; that would be abandonment and would increase harm. I would document the shared decision, provide naloxone, and involve social work and addiction medicine. If he refuses all options, I would still offer a safe taper and referral, and document that he was not abandoned.
3. What would you do if he becomes agitated and demands his prescription before leaving?
Read the worked answer
I would stay calm, set a clear boundary, and avoid escalating. I would acknowledge his distress and explain that I cannot prescribe more opioids today because of the safety concerns, but I can offer treatment for withdrawal, naloxone, and an urgent appointment with addiction medicine. If he is intoxicated or threatening, I would follow clinic safety protocols and involve security; if he is in withdrawal, I would treat it symptomatically and not withhold care. I would not negotiate a refill under pressure, because that reinforces unsafe prescribing. I would document the interaction objectively and ensure a follow-up plan is in place before he leaves. The goal is to keep him engaged in care while maintaining a safe prescribing boundary.
