Resumen

Introduction: The improper disposal of expired medications poses a risk to public health and the environment. Household practices for managing pharmaceutical waste are often inadequate, highlighting the importance of studying and improving final disposal strategies. Objective: To assess the level of knowledge and disposal practices regarding expired medications within the community. Methods: A descriptive, cross-sectional study was conducted using structured surveys applied to a non-probabilistic sample of 234 patients. Three main variables were evaluated: knowledge, attitudes, and practices related to the disposal of expired medications. Data were analyzed using descriptive statistical methods, including frequencies, percentages, and measures of central tendency. Results: Sixty-five percent of respondents reported discarding medications in household trash, while only 15% chose to return them to pharmacies or designated collection centers. The remaining 20% followed other practices, such as pouring them down the drain, which increases the risk of water resource contamination. The main reasons cited were lack of awareness of proper disposal methods and the absence of accessible collection programs. Conclusions: Inadequate medication disposal practices in households in Lima, underscoring the need to implement educational campaigns and public policies that promote safe and sustainable practices. In addition to demonstrating the need for collaboration between health and environmental institutions, it is essential to mitigate risks and foster responsible citizen awareness regarding the management of expired medications.
