LUCEMYRA may be used concomitantly with other medication-assisted treatments (MAT)1

  • LUCEMYRA has been studied concomitantly with commonly used therapies for Opioid Use Disorder, such as buprenorphine, methadone, and naltrexone
    • LUCEMYRA and methadone both prolong the QT interval. ECG monitoring is recommended in patients receiving methadone and LUCEMYRA
    • It is possible that oral naltrexone efficacy may be reduced if used concomitantly within 2 hours of LUCEMYRA
      • This interaction is not expected if naltrexone is administered by non-oral routes
