Nonfatal pediatric fentanyl exposures reported to US poison centers, 2015-2023.

The opioid crisis, driven by fentanyl use, continues to worsen in the US and there has been a lack of focus on nonfatal overdose and how pediatric populations are being affected. We determined the prevalence of nonfatal pediatric fentanyl exposures and associated characteristics and delineated how such characteristics are associated with major (life-threatening) outcomes. This repeated cross-sectional study examined characteristics of pediatric nonfatal fentanyl exposures (aged 0-19 years) reported to poison centers in 49 US states from 2015 through 2023.
