New study tests monthly shot to help people stop using fentanyl

This study compares a once-monthly injection of buprenorphine to daily sublingual buprenorphine for treating opioid use disorder in people who use fentanyl or other strong synthetic opioids. About 60 adults aged 18–65 will be enrolled and followed for 4 weeks after starting treatment. The goal is to see which approach leads to more days without drug use and fewer relapses.
