Is Your Medicine Cabinet a Health Hazard? How Community Health Workers Can Help
"Uncover the hidden dangers in your home medication storage and how a simple strategy can ensure your family's safety."
In the world of healthcare, the Family Health Strategy (FHS) stands as a critical approach, emphasizing teamwork among diverse professionals to promote health and prevent disease. Community Health Agents (CHAs) are central to this strategy, conducting vital educational activities in homes and communities. But going beyond the conventional focus on treating diseases, the FHS also involves understanding the complex dynamics within families, shaped by their environment and relationships. It is important to know the community's health profile to make health initiatives more relevant and effective.
One underestimated aspect is how families manage their medications at home. The Brazilian Ministry of Health recognizes this, aiming to transform CHAs into promoters of the rational use of medicines. This includes ensuring that medicines are of good quality and stored correctly to maintain their effectiveness.
Homes often accumulate medicines from past treatments, prescriptions for chronic conditions, and self-medication practices, all of which can pose significant health risks. Inappropriately stored medications can lead to irrational consumption, wastage, increased risk of accidental poisoning, and other toxic exposures. This article will explore findings from a study conducted in a city in Rio Grande do Sul, Brazil, to evaluate medication storage practices in communities served by the FHS.
Medication Safety and Patient Harm
The CDC describes adverse drug events (ADEs) as harm caused by a medication and identifies them as a serious public health threat. It notes that adults often take more medicines as they get older, increasing their risk of an ADE. AHRQ’s medication and other substance dashboard covers reported patient-safety concerns, including incidents, near misses, and unsafe conditions. The 2024 Network of Patient Safety Databases Chartbook examines reported events, including where errors occur in the process, human contributors, and the share resulting in patient harm.
Building Medication Safety Practices
A 2026 systematic review describes a challenge in community healthcare: the lack of widely accepted standardized instruments makes organizational culture and medication safety difficult to measure operationally. The National Association of Community Health Centers’ session covers the health center movement’s origins and milestones from 1960 to the present. A separate account of medication reconciliation describes the World Health Organization’s International High 5s Project, which treats reconciliation as a core patient-safety component and defines it as a formal process for professionals and patients to ensure medication information is accurate and complete.
The Reality of Home Medicine Storage: Key Findings
The study examined 473 households across five FHS areas, revealing that a significant 98.7% had at least one medication in stock. This confirms that keeping medicines at home is a widespread practice. Further analysis identified critical issues related to storage conditions:
- Exposure to Heat, Humidity, and Light: 43.5% of storage places exposed medicines to heat, 39.6% to humidity, and 16.5% to light.
- Accessibility to Children: In 42% of homes, medications were within reach of children, highlighting a significant risk of accidental ingestion.
- Expired Medications: 6.9% of the medicines had already expired, making them potentially harmful.
- Packaging and Information: A concerning 35.3% of medicines were not in their secondary packaging, and 67.9% lacked patient information leaflets.

Community Health Workers and Medication Use
A study titled “Complexidades do trabalho do agente comunitário de saúde com pacientes em uso de medicamentos” examines the complexities of community health workers’ work with patients who use medicines. Its abstract excerpt says workers should be prepared to help users overcome barriers when guidance from prescribers and pharmacists is insufficient or has not been provided. The excerpt cites earlier work by Kauling et al. (2013), Laste et al. (2012), Marodin et al. (2011), and Nunes, Amador and Heineck (2008).
Gaps in Community Pharmacy Safety
A 2025 systematic review notes that, although medication safety has been a public health concern since the Institute of Medicine’s 1999 report “To Err is Human,” there is less evidence about medication errors in community pharmacies than about formal hospital systems. A 2023 evaluation describes mandated reporting of community pharmacy errors—including incidents leading to inappropriate medication use and near misses intercepted before reaching patients—as a potential source of learning to prevent future events. A 2025 scoping review focuses on the types of errors most commonly found during community pharmacy services. Another 2025 review calls for assessment of medication safety in regions with limited pharmacy access and a standardized global reporting framework.
The Path Forward: Empowering Communities for Safe Medication Practices
The study's findings underscore the urgent need for multi-professional teams to actively promote health and educate communities on the rational use and proper storage of medicines. Community Health Agents are invaluable in this effort. Their routine household visits enable them to identify and address issues related to medication storage and usage directly.
Collaboration Around Medication Safety
An expert commentary on community pharmacy collaboration says it is important to understand what limits or enables pharmacists’ participation in medication-safety activities. It identifies medication review as a common form of collaboration. A qualitative observational study of outpatient medication use set out to examine diverse patients’ experiences across the medication-use process to inform interventions for safer medication use in community settings. Its researchers conducted approximately 18 hours of direct observation across multiple settings.
The Future of Community Pharmacy
A 2026 article, “Beyond the Counter: The Community Pharmacist of the Future,” argues that expanding pharmacists’ roles could align care with places convenient for patients and build on relationships already imbued with trust; its authors also describe structural changes needed for that transformation. A 2024 Journal of the American Pharmacists Association commentary identifies community pharmacies as gateways to primary care and public health, but projects that 20%–30% of community pharmacy locations could close within the next year. The commentary frames systemic change as critical to the future of community pharmacy.
System-Level Supports for Safer Medication Use
A systematic review of medication errors in primary healthcare describes them as a significant global health challenge and calls for multifaceted interventions. The approaches it highlights include better communication and education, standardized protocols, clinical pharmacy integration, and patient-centered care. A 2025 review of community pharmacists’ roles also highlights collaboration with physicians and patient education, and argues that systemic changes are needed to support comprehensive medication management and improve patient safety.
Medication Safety at Home
A study of communities served by Brazil’s Family Health Strategy found a need for a multiprofessional team to promote health and rationalize household medicine stocks. It described the community health worker as indispensable to promoting the rational use of medication. A qualitative study of community pharmacy safety sought to identify sociotechnical factors staff encounter in practice and how those factors may affect medication safety.
Given the high prevalence of self-medication and easy access to analgesics, CHAs can play a vital role in educating families about the risks of improper medication use and storage. They can advise on safe storage practices, the importance of keeping medicines out of reach of children, and the need to dispose of expired or unused medications properly.
By empowering CHAs with the knowledge and resources to promote safe medication practices, healthcare systems can enhance community health and reduce the risks associated with improper medication storage and use. Support from a multi-professional team, including pharmacists, through initiatives like the Family Health Support Centers is a way to provide complete solutions to bettering medication mangement in community.
