Adults with opioid use disorder who receive a higher daily dose of the opioid addiction treatment medication buprenorphine may have a lower risk of subsequent emergency department visits or use of inpatient services related to behavioral health (such as for mental health and substance use disorders) than adults receiving the recommended dose, according to an analysis funded by the National Institutes of Health (NIH). These findings suggest that higher buprenorphine doses could be more effective in managing opioid use disorder, which may be particularly relevant for improving treatment for those who use fentanyl, a major driver of the overdose crisis.
