IntroductionCoprescribing naloxone with opioids could reduce the risk of overdose. By the end of 2020, 8 U.S. states implemented coprescribing laws requiring the prescription of naloxone alongside certain opioid prescriptions. This study examined the impacts of state laws that require coprescribing opioids and naloxone on codispensing practices.MethodsData included opioid prescriptions for commercially insured adults between 2014 and 2020. Augmented synthetic control analyses were used to examine the impacts of 8 coprescribing requirement laws implemented between 2017 and 2020 on the proportion of opioid prescription fills with a naloxone coprescription fill. Analyses were completed in spring 2023.ResultsChanges in the proportion of opioid prescription fills with a naloxone coprescription fill attributable to the laws varied across states. In 4 states (New Jersey, New Mexico, Rhodes Island, and Virginia), laws were associated with 0.8 (95% CI=0.3, 1.3) to 4.4 (95% CI=3.4, 5.4) percentage point increases in the proportion of opioid prescriptions with a naloxone coprescription fill (p<0.05). There were no statistically significant changes attributable to the other state laws (Arizona, Florida, Vermont, Washington).ConclusionsLaws requiring coprescribing naloxone with certain opioid prescriptions are associated with small-in-magnitude increases in codispensing in some states. Broadening the categories of opioid prescriptions covered in naloxone coprescribing requirement laws and implementing health system strategies to encourage providers to coprescribe naloxone could help to magnify the impacts of these laws.Copyright © 2023 American Journal of Preventive Medicine.
