[ References ](#references-heading) A patient taking buprenorphine for OUD is admitted with a painful vertebral fracture. The admitting order continues buprenorphine but offers only acetaminophen because the team fears that additional opioids will cause relapse. By morning, the patient is still in severe pain and wants to leave. **Treat the injury and protect recovery at the same time**; withholding indicated analgesia does neither. [\[1\]](#cite-1 "Reference [1]") Start With Two Separate Treatment Goals --------------------------------------- ### Control pain without destabilizing OUD Ask what is causing the pain, what the patient takes for OUD, when they last took it, and what has worked previously. Assess pain alongside function, withdrawal, sedation, and respiratory status. A request for analgesia is not, by itself, evidence of drug-seeking; opioid tolerance, withdrawal, and a new painful illness can coexist. [\[1\]](#cite-1 "Reference [1]") Medication for opioid use disorder (MOUD) treats OUD but does not necessarily cover acute pain throughout the day. Methadone and buprenorphine suppress withdrawal longer than they provide analgesia. The common board-exam error is to count the maintenance dose as the entire pain plan—or to stop it when pain treatment becomes necessary. [\[1\]](#cite-1 "Reference [1]") - Verify the medication, dose, formulation, and last administration. Contact the opioid treatment program (OTP) for methadone; use available prescribing records and the patient’s account for buprenorphine. - Treat a missed maintenance dose or emerging withdrawal promptly. Withdrawal can amplify distress and complicate pain assessment. - Set a shared target: tolerable pain that permits examination, sleep, mobilization, and treatment—not necessarily a zero pain score. [\[1\]](#cite-1 "Reference [1]") Continue Agonist MOUD, Then Add Analgesia ----------------------------------------- ### Buprenorphine: do not reflexively stop it Continue a patient’s established buprenorphine during most acute pain episodes, including hospitalization and surgery. Its strong μ-receptor affinity does **not** make full-agonist analgesia impossible. Stopping it can produce withdrawal and complicate return to OUD treatment; continuation is supported by expert consensus and observational evidence, although comparative trials remain limited. [\[2\]](#cite-2 "Reference [2]") For an acute pain episode, consider dividing the existing total daily buprenorphine dose into doses given every six to eight hours. This uses its shorter analgesic duration without abandoning maintenance treatment. For moderate to severe pain, add a carefully titrated short-acting full agonist when nonopioid measures are insufficient; hydromorphone or fentanyl may be useful because of their receptor affinity. Anticipate opioid tolerance, but never substitute a fixed ‘tolerance dose’ for reassessment of analgesia and sedation. [\[3\]](#cite-3 "Reference [3]") ### Methadone: maintenance is not a PRN pain order Verify and continue the patient’s established methadone maintenance dose unless an acute contraindication requires reassessment. Give **additional analgesia** for the new pain; do not assume a once-daily OTP dose will cover a fracture, abscess, or postoperative wound. Splitting a verified maintenance dose during hospitalization can sometimes help analgesia, but coordinate changes with the OTP and plan for the usual outpatient schedule at discharge. [\[1\]](#cite-1 "Reference [1]") Check for sedation, respiratory compromise, interacting sedatives, and QT-related concerns when clinically relevant. If doses have been missed or the reported dose cannot be verified, do not blindly administer a large ‘home dose’: tolerance may have changed. Involve pharmacy, the OTP, or addiction medicine to establish a safe plan. [\[1\]](#cite-1 "Reference [1]") > **Clinical Pearl:** Continue maintenance buprenorphine or methadone for OUD, then prescribe analgesia for the painful condition. One order should not be expected to do both jobs all day. [\[1\]](#cite-1 "Reference [1]") Build a Multimodal Plan Around the Illness ------------------------------------------ ### Match each intervention to a pain mechanism Use scheduled acetaminophen when appropriate and an NSAID when renal function, bleeding risk, gastrointestinal risk, and the underlying illness permit. Add local or regional anesthesia for procedures when feasible; consider physical measures and early mobilization as the condition allows. For complex severe pain, ask an acute pain team about options such as ketamine or regional techniques rather than escalating opioids alone. [\[2\]](#cite-2 "Reference [2]") Treat the source: drain an abscess, stabilize a fracture, or address ischemia. If opioids are needed, use a defined indication, reassess function and adverse effects, and adjust for organ dysfunction and other sedating drugs. **Multimodal** means combining useful mechanisms—not adding every drug regardless of contraindications. [\[4\]](#cite-4 "Reference [4]") Naltrexone requires a different plan because it blocks opioid effects rather than activating the receptor. Identify its formulation and last dose early; prioritize nonopioid and regional options, and obtain specialist support for severe pain. Do not try to overcome an active blockade with escalating unmonitored opioids: opioid sensitivity can change as blockade wanes. Coordinate naltrexone resumption after opioid analgesics have stopped and an appropriate opioid-free interval has passed. [\[5\]](#cite-5 "Reference [5]") Discharge Is Part of Pain Treatment ----------------------------------- Before discharge, agree on when any added full agonist will stop or taper as pain improves. Communicate buprenorphine changes to its prescriber and methadone arrangements to the OTP; confirm access to the next maintenance dose. Offer naloxone, explain overdose risk and safe medication storage, and arrange follow-up that addresses both pain and OUD. [\[3\]](#cite-3 "Reference [3]") Key Takeaways ------------- - **Do not undertreat acute pain because a patient has OUD.** Assess the painful condition, withdrawal, function, and safety separately. [\[1\]](#cite-1 "Reference [1]") - Continue verified buprenorphine or methadone maintenance in most cases; add a separate, reassessed analgesic plan. [\[2\]](#cite-2 "Reference [2]") - Split buprenorphine dosing when useful for analgesia, and use full agonists for severe pain when indicated. [\[3\]](#cite-3 "Reference [3]") - Check for naltrexone before relying on opioid analgesics. [\[5\]](#cite-5 "Reference [5]") - Make the transition back to the outpatient MOUD regimen explicit. [\[1\]](#cite-1 "Reference [1]") Conclusion ---------- The safest plan is neither ‘no opioids’ nor ‘opioids alone.’ Maintain OUD treatment, treat the cause of pain, layer analgesic strategies, and leave the patient with a workable follow-up plan. [\[1\]](#cite-1 "Reference [1]") Frequently Asked Questions ---------------------------- ### Should buprenorphine be stopped before treating severe acute pain? Usually not. Continue established buprenorphine, use multimodal analgesia, and add a titrated full-agonist opioid when clinically indicated. [\[2\]](#cite-2 "Reference [2]") ### Does a daily methadone maintenance dose cover pain from a new injury? No. Continue the verified maintenance dose and assess the need for additional analgesia; its pain relief generally lasts less time than withdrawal suppression. [\[1\]](#cite-1 "Reference [1]") ### What changes if the patient receives naltrexone? Check the formulation and last dose. Opioid analgesia may be blocked, so prioritize nonopioid and regional approaches and seek specialist help for severe pain. [\[5\]](#cite-5 "Reference [5]") ### What is the most important discharge step after adding short-acting opioids? Document a stop or taper plan, confirm uninterrupted MOUD access and follow-up, and offer naloxone. [\[3\]](#cite-3 "Reference [3]") References (5) ------------------ 1. 1.
