Conditions
Summary
The goal of this clinical trial is to learn whether a combined behavioral and pharmacologic intervention can help reduce opioid use, improve pain recovery, and prevent opioid misuse after surgery in adults undergoing elective surgery. The study includes adults aged 18 to 75 who have a history of long-term opioid use, defined as having access to opioids for 60 or more days within the 180 days before surgery. The main questions it aims to answer are: * Does Motivational Interviewing with guided opioid tapering plus tizanidine (MI-Opioid Taper + Tizanidine) help participants return to their preoperative opioid use level or stop opioids faster than Enhanced Usual Care (EUC)? * Does the intervention reduce the time to pain resolution and decrease the likelihood of opioid misuse after surgery compared to EUC? Researchers will compare MI-Opioid Taper + Tizanidine to MI-Opioid Taper with placebo and to EUC to see whether the intervention improves postoperative opioid and pain outcomes. Participants will: * Complete a phone assessment and baseline survey before surgery * Be randomly assigned 7-13 days after surgery to one of three groups: * MI-Opioid Taper + tizanidine (MTT) * MI-Opioid Taper + placebo (MTP) * Enhanced Usual Care (EUC) * Complete brief weekly phone or video visits with a study clinician for 6 weeks starting 14 days after surgery * Take a study medication (tizanidine or placebo) three times daily for 5 weeks (MTT and MTP groups only) * Complete weekly online surveys for 6 months, followed by monthly surveys until 12 months after surgery to track pain, opioid use, and related outcomes

- Alcohol Use Disorders Identification Test (AUDIT-C): score ≥4 (men), ≥3 (women)
- Modified Brief Pain Inventory (mBPI): "Yes" to at least one of the following:
- Over the past 24 hours have you needed to take your pain medication to help you sleep?
- Have you taken any pain medications for any reason other than your pain, such as to reduce anxiety or improve mood?
- Have you taken more pain medication than was prescribed to you in the past 24 hours?
- At the Post-Operative Call (7-13 days post-op): Postoperative daily opioid dose ≥ preoperative daily opioid dose (identified during the Pre-Surgery Call 5-1 day before surgery), measured in Morphine Milligram Equivalents (MME).

- Pre-existing hypotension, sedation, dizziness, severe respiratory insufficiency.
- Opioid Use Disorder
- Suicidality as assessed by the Patient Health Questionnaire-9 (PHQ-9) Question 9 score ≥ 1
- Pregnancy, breastfeeding, or planning to conceive

Interventions
Tizanidine 2mg three times a day for 5 weeks after surgery
Motivational Interviewing (MI) and guided Opioid Tapering support adapting MI principles for enhancing motivation to change in pain treatment and tailoring key MI tools to postoperative opioid use delivered through weekly phone calls from weeks 2 to 7, and at week 11. The guided opioid tapering protocol will be a 25% total daily opioid dose reduction every 7 days with opioid discontinuation 7 days after reaching 1 opioid pill per day.
1 tablet three times a day for 5 weeks after surgery
Participants will receive weekly phone calls from weeks 2 to 7, and at week 11. 1 topic per call will be reviewed in this sequence:1) standardized instructions on taking opioid medications after surgery, 2) safe opioid use, 3) avoiding medication errors, 4) local mental health resources and 988 Suicide \& Crisis lifeline, 5) disposal of unused medications, 6) prescription drug abuse, and 7) complementary health approaches for chronic pain. Education materials will be reviewed in a didactic style without a tailored discussion.
