Abstract

In a randomized controlled trial among Addis Ababa's community pharmacies, we implement informational interventions to curb over-the-counter (OTC) antibiotic sales, which, especially in developing countries, contribute to the development of antimicrobial resistance (AMR). Our results show that one-time letters to pharmacists and a poster placed within the pharmacy premises significantly reduce OTC antibiotic sales in the short-run, with the poster's effect persisting five months later. We observe no significant impact on antibiotic prices. These findings highlight the potential of targeted informational interventions to tackle OTC antibiotic dispensing and mitigate the growing AMR threat.
