Behind the Paper: The High Financial Cost of Taking "Too Many" Medicines in Nigeria
Published in Pharmacy & Pharmacology, Public Health, and Economics
When a patient walks into a clinic, receiving a prescription is supposed to be the first step toward healing. But what happens when that single visit ends with a prescription for five, eight, or more than ten different drugs at once? In low- and middle-income countries like Nigeria, where health insurance covers only a fraction of the population and healthcare is paid almost entirely out-of-pocket, taking multiple medications can transform a routine health check into a devastating financial crisis.
Our team set out to investigate this precise dilemma at Offa Specialist Hospital in Kwara State, Nigeria. We wanted to know: how widespread is polypharmacy in a secondary healthcare setting, and what does it actually cost the patients on the receiving end?
The Dual Realities: Prescription Records vs. Daily Survival
To get the full story, we combined two research perspectives: a retrospective review of 2,000 prescriptions and a prospective survey of 100 patients and 50 healthcare professionals.
The Scale of the Problem: Over 37% of reviewed prescriptions met the criteria for polypharmacy (5 or more medications), with 12% involving "excessive polypharmacy" of 10 or more drugs. The average prescription contained 4.8 drugs.
The Cost Barrier: Among surveyed patients, 37% spent over ₦20,000 per month on drugs, with an average expenditure of ₦18,600. For 79% of patients, these costs represented a major financial burden.
Dangerous Compromises: High costs forced 66% of patients to skip doses, reduce medication intake, or delay purchases. Additionally, 78% depended on financial help from family and friends just to pay for their prescriptions.
Bridging the Gap: What Healthcare Providers See
The study revealed an overwhelming consensus among clinicians. Every single healthcare provider surveyed (100%) agreed that polypharmacy drives up treatment costs, and 84% noted that they frequently care for patients taking five or more medications. Crucially, 72% of providers recognized that some prescribed medications could be safely reduced through structured medication reviews.
Our findings underline an urgent need to rethink prescribing habits. Addressing polypharmacy isn't just a clinical goal to avoid adverse drug interactions—it is an economic lifeline for patients navigating out-of-pocket healthcare. Integrating routine medication reviews, strengthening clinical pharmacology collaboration, and expanding universal health coverage are critical steps to ensuring that treating an illness doesn't cause a financial crisis.

Strengthening health system resilience: from emergency preparedness to response and recovery
Health systems worldwide are increasingly facing the dual challenges of rising health demands and the unpredictability of emergencies. Recent and ongoing polycrises—whether the COVID-19 pandemic, sporadic outbreaks of emerging or reemerging diseases, or increasingly frequent emergencies resulting from natural hazards—have highlighted the urgent and compelling need for enhanced health system preparedness and resilience. Effective emergency preparedness involves not only robust planning and response strategies but also the capability to adapt and recover quickly from disruptions. This Collection aims to explore the multifaceted aspects of strengthening health systems to ensure they can effectively prepare for, respond to, and recover from emergencies and maintain continuity of care.
Addressing the resilience of health systems is crucial for safeguarding public health and ensuring that healthcare providers can deliver effective services during crises. Recent advancements have included the integration of technology in health management, improved supply chain logistics, and enhanced workforce training. Furthermore, frameworks for assessing health system resilience have been developed, offering valuable insights into best practices. However, ongoing research is needed to evaluate the effectiveness of these strategies and to implement innovative solutions that can be adapted to various contexts and crises.
Topics for submission but are not limited to:
- Governance, leadership, and policy approaches for resilient health systems
- Frameworks and metrics for assessing and strengthening health system preparedness and resilience
- Financing mechanisms and economic resilience of health systems in emergencies
- Community engagement and locally led strategies in crisis preparedness, response and recovery
- Workforce training, surge capacity, and capability building for emergency response
- Supply chain management and essential resource security during emergencies
- Digital technologies and data-driven innovations for emergency preparedness, response and recovery
- Health system resilience in underserved, vulnerable, or fragile settings
This Collection supports and amplifies research related to SDG 3: Good Health and Well-being.

Strengthening private and public health insurance models for affordability of health services and financial protection
The rising costs of healthcare and the increasing burden of out-of-pocket expenses have underscored the need for effective health insurance models that promote financial protection and affordability. This Collection aims to explore innovative approaches to strengthen both private and public health insurance systems, focusing on risk pooling, equitable access, and coverage expansion. By examining various insurance frameworks, we aim to understand how they can better serve populations, particularly in low- and middle-income countries where catastrophic health expenditures are prevalent.
Advancements in health insurance models have demonstrated the potential to significantly reduce financial barriers to healthcare access, contributing to improved health outcomes. Research has shown that effective risk pooling mechanisms and the implementation of universal health coverage (UHC) can mitigate catastrophic health expenditures and enhance the quality of healthcare services. As health systems worldwide face increasing pressures, it is crucial to identify and share best practices that ensure equitable access to essential health services while maintaining financial sustainability.
Topics for submission:
- Strategies for cost reduction in health insurance
- Addressing catastrophic health expenditure through insurance
- Reducing out-of-pocket costs for vulnerable populations
- Enhancing risk pooling for equitable access
- Advancing universal health coverage (UHC) initiatives
