Treatment of Acute Pain in Opioid Use Disorder
Full update April 2023
The FAQ below covers common clinical questions that arise about treating pain in patients with OUD. Keep in mind that high-level evidence to guide management in these patients is lacking.4 Most of the information below is based on expert opinion. For information on non-opioid options, see our chart, Analgesics for Acute Pain in Adults.

What are some special considerations for patient assessment before treating acute pain in this patient population? |
Identify all opioids the patient might be using. Check your prescription drug monitoring program, and perform a urine drug screen that includes methadone, buprenorphine, and fentanyl.4 Obtain a pain history.4 Identify any medications which, if discontinued, could cause withdrawal symptoms.4 This would be of particular concern if the patient is going to surgery. Ask about comorbidities, including psychiatric disorders.4
Consider comorbidities when choosing non-opioids (e.g., consider anticonvulsants if the patient has neuropathic pain).18 Assess pain using your institution’s usual pain assessment tool.2 |
What are some points to address with patients with opioid use disorder regarding acute pain treatment? |
Patients with OUD may have the following concerns regarding control of acute pain:
|
What is the general approach to treatment of acute pain in patients with opioid use disorder? |
Individualize the treatment plan, taking into account patient preferences.12 Patients with a history of opioid misuse may not want to take opioids.12 Patients with a history of opioid misuse are at risk for relapse triggered by anxiety or pain associated with injury or surgery.4 Therefore, pain control in these patients requires planning (when possible), education, monitoring, and increased support.4
Keep in mind that some non-opioids (e.g., gabapentin) pose abuse risk.24 Prescribe/dispense opioids in small quantities (e.g., three to seven days).2 Consider enlisting a reliable family member to serve as the custodian of the medication.21 In the hospital, switch from parenteral to oral opioids as soon as possible.2 The oral route is less reinforcing.5 Taper opioids as pain resolves.2 Refer for addiction treatment.2 See our chart, Management of Opioid Use Disorder, for information on MAT for OUD. Educate patients about opioid overdose, and strongly consider prescribing naloxone.2 |
What are some special considerations for treating pain in patients actively abusing an opioid (e.g., heroin)? |
Accurately assess the patient’s current opioid use and convert to morphine equivalents.18 This can be used as the patient’s baseline opioid requirement.18 Additional opioid will be added for analgesia.18

How should pharmacists handle acute opioid prescriptions for patients with a history of opioid use disorder? |
Consider contacting the prescriber if more than a week’s supply of opioid is prescribed. Consider providing naloxone. If the patient is on MAT, ensure that the MAT prescriber is aware of the opioid prescription. If the prescriber of the acute opioid prescription is not the patient’s usual prescriber, ensure that their primary care prescriber is aware of the prescription. If a MAT patient’s buprenorphine regimen has been changed to address acute pain (e.g., higher dose, more frequent dosing), a new prescription might be needed for insurance coverage. Chose the most appropriate buprenorphine product to provide the patient’s new dose to avoid cutting tablets or films. |
How do you treat acute pain in patients receiving buprenorphine MAT? |
Patient taking buprenorphine/naloxone: Prescribers can divide the total daily buprenorphine dose every six to eight hours to enhance buprenorphine’s analgesic effects.9,20 (Buprenorphine’s long half-life and high receptor affinity allows once-daily dosing for opioid dependence, but its analgesic effect may only last six hours.20,22) This approach allows the patient to continue on a stable buprenorphine dose.12 More buprenorphine (sublingual or IV) can be added to their maintenance dose for pain in those taking less than 32 mg daily (of sublingual tablet, or equivalent).7 (Note that the max buprenorphine dose is 24 mg per Canadian labeling.)8 High doses of other opioids may be needed to overcome strong mu receptor blockade by buprenorphine, as well as tolerance.3,9 Hydromorphone or fentanyl (e.g., in inpatients) might be good choices due to their relatively high affinity for mu opioid receptors.12,20 If buprenorphine is subsequently stopped with mu agonists on board, monitor for sedation and respiratory depression due to mu receptor hypersensitivity.9 In surgical patients:
If the need for opioids may be of long duration, consider temporary discontinuation of buprenorphine (perhaps with substitution of methadone 20 to 40 mg) to facilitate opioid use.9 When restarting buprenorphine after discontinuation, follow an induction protocol.9 Buprenorphine should not be started until the opioid is stopped.12 Patients should be exhibiting early symptoms of withdrawal before the first buprenorphine dose to prevent withdrawal precipitated by buprenorphine/naloxone.9,12 See our chart, Management of Opioid Use Disorder, for guidance on buprenorphine induction protocols/dosing and transitioning from an opioid to buprenorphine. Patient treated with Probuphine or Sublocade: Can use a “full opioid” if needed, with monitoring for respiratory depression. High doses may be needed.13-15 |
How do you treat acute pain in patients receiving methadone MAT? |
Patient taking methadone: If an opioid is needed, the methadone maintenance dose (check with clinic) is considered the patient’s baseline, and another opioid is added for pain control.12 A relatively high dose may be needed.2 (Note that methadone maintenance can be continued in the hospital; the prescriber does not need a waiver for patients admitted primarily for other reasons.12) Avoid mixed agonist/antagonists or partial agonists like buprenorphine, pentazocine, butorphanol, or nalbuphine; they may precipitate withdrawal.4,17 |
How do you treat acute pain in patients receiving naltrexone MAT? |
Patient taking naltrexone: If a patient on Vivitrol requires elective surgery, try to delay surgery to allow naltrexone levels to drop (e.g., at least four weeks after last injection).4,19 For oral naltrexone, allow a 72-hour washout.4 Keep in mind that these patients can have an exaggerated response to any opioids administered perioperatively.4
In an emergency, naltrexone’s effects can be overcome with higher than usual opioid doses. These high doses increase the risk of respiratory depression.19 If a patient on oral naltrexone requires continued high dose opioids in an emergency, the patient may experience toxicity as oral naltrexone levels wane.23 Inpatient or prolonged emergency department monitoring is needed so that patients can be monitored by professionals trained in the use of anesthetic drugs, management of respiratory depression, and cardiopulmonary resuscitation (CPR).19,23 |
