Evaluating patient knowledge and use of medication disposal in a Chinatown community pharmacy.

Background: Drug take-back programs (TBPs) provide the opportunity to safely dispose of unused or expired medications (UEMs), potentially reducing the risk of environmental harm and morbidity. Data on patient perceptions and participation are limited, especially in underserved Asian populations.

Objective: This study aimed to evaluate medication disposal perceptions and behaviors through a free mail-in medication disposal program among patients in a Chinatown community pharmacy.
