Naloxone Availability in Retail Pharmacies and Neighborhood Inequities in Access

Abstract

This study examines the implementation of North Carolina's statewide naloxone standing order and identifies community characteristics associated with pharmacy stocking and willingness to sell naloxone under the standing order. In April-June 2019, a mystery caller protocol was completed to assess if (1) North Carolina pharmacies had naloxone available and were willing to dispense it without a prescription, (2) pharmacy characteristics associated with availability, and (3) there were neighborhood differences (e.g., Census tract population size, density, racial composition, SES, rates of opioid overdoses, and rates of opioid prescriptions dispensed) in availability. Using random sampling stratified by inclusion on North Carolina's public list of pharmacies participating in the standing order, chain, independent, and health department pharmacies in North Carolina were sampled (n=161 of 2,044). In June 2019, the data were analyzed. Survey weights were utilized to calculate the prevalence of availability, and regression models were conducted to examine associations. An estimated 61.7% (95% CI=54.3, 68.5) of North Carolina retail pharmacies have naloxone available without a prescription. The odds of naloxone availability were lower for independent pharmacies than chains (OR=0.12, 95% CI=0.06, 0.25). Inclusion on North Carolina's public list of pharmacies had greater odds of naloxone availability (OR=2.32, 95% CI=1.22, 4.43). Naloxone availability was lower in communities with higher percentages of residents with public health insurance (OR=0.97, 95% CI=0.95, 0.999). Though more than half of the pharmacies in North Carolina participate in the standing order for naloxone, efforts to identify the best practices for ensuring widespread implementation of statewide standing orders for naloxone are warranted.
