Non-buprenorphine opioid utilization among patients using buprenorphine.

Abstract

Buprenorphine is commonly used to treat opioid use disorder; however, non-buprenorphine prescription opioid use among these patients is not well defined. We sought to estimate the prevalence of non-buprenorphine opioid use among incident buprenorphine users and quantify levels of opioid use prior to, during and after the first treatment episode.
