Results support use of weekly extended-release buprenorphine for opioid use disorder during pregnancy

In a clinical trial, a research team found that administering weekly injectable extended-release buprenorphine for treatment of opioid use disorder (OUD) during pregnancy led to higher rates of abstinence from illicit opioids than buprenorphine given daily under the tongue (sublingual), one of the standard methods of treatment. Additionally, serious adverse events were less common in those receiving extended-release treatment.
