1.1 Introduction
Antibiotics are chemical substances used to inhibit the growth of or destroy pathogenic microorganisms, particularly bacteria, and are essential for the prevention and treatment of infectious diseases (World Health Organization [WHO], 2014). The abuse of antibiotics involves the use of these drugs without proper medical guidance, incorrect dosing, incomplete treatment courses, and the use of antibiotics for conditions where they are not indicated, such as viral infections (Auta et al., 2012). In Nigeria, the ease of access to antibiotics without prescription, coupled with limited public awareness and inadequate enforcement of regulatory policies, is creating a public health crisis. Self-medication and unregulated sales of antibiotics in pharmacies and informal markets is widespread, leading to inappropriate use and escalating the prevalence of antibiotic-resistant bacteria (Okeke et al., 2005; Fadare et al., 2016).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitation of the study and Definition of terms.
1.2 Background of the Study
In Nigeria, antibiotics were first introduced into the healthcare system during the mid-20th century as part of efforts to control infectious diseases such as typhoid, tuberculosis, and pneumonia (Okeke et al., 2005). Initially, their use was regulated and confined largely to hospitals and licensed pharmacies. However, with time, factors such as population growth, urbanization, and inadequate healthcare infrastructure facilitated the widespread availability of antibiotics, often without prescription. It is reported that the proliferation of informal drug vendors and poorly monitored pharmacies contributed to the indiscriminate use of these medications (Auta et al., 2012).
The misuse of antibiotics became more pronounced in the late 20th and early 21st centuries. Studies conducted by Olayinka et al. (2020) affirmed that self-medication, incomplete dosing, and the use of antibiotics for viral infections became common practices, driven by low awareness of antimicrobial resistance, economic constraints, and cultural beliefs regarding medicine. Fadare et al. (2016) contended that the unregulated access to antibiotics and the weak enforcement of drug policies exacerbated the problem, leading to a surge in antibiotic-resistant infections in both urban and rural communities.
Antibiotics are pivotal in modern medicine for the treatment and prevention of bacterial infections. According to the World Health Organization (2014), antibiotics are substances that either kill or inhibit the growth of bacteria, playing a crucial role in reducing morbidity and mortality from infectious diseases. However, the misuse and abuse of these drugs has become a significant public health concern worldwide.
In Nigeria, the abuse of antibiotics is prevalent due to factors such as self-medication, easy access to antibiotics without prescription, inadequate public awareness, and poor enforcement of drug regulations. Auta et al. (2012) reported that many individuals in Nigeria obtain antibiotics from pharmacies or informal drug vendors without proper medical consultation, often using them for viral infections or stopping treatment prematurely. Okeke et al. (2005) asserted that these practices contribute to the emergence of antibiotic-resistant bacteria, which is now a major challenge for healthcare providers in the country.
Fadare et al. (2016) stated that the continuous misuse of antibiotics not only reduces their effectiveness but also leads to treatment failures, prolonged illnesses, and increased healthcare costs. Olayinka et al. (2020) affirmed that the rise in multidrug-resistant infections is placing enormous pressure on healthcare systems, complicating the management of common infections and increasing the risk of mortality. On the other hand, the public’s limited knowledge of the consequences of antibiotic resistance and the socio-economic factors driving self-medication underscore the complexity of addressing this issue (Auta et al., 2012). This study is set against the backdrop of understanding the extent of antibiotic abuse in Nigeria, its impact on the health of the population, and the strategies necessary to mitigate its harmful effects.
1.3 Statement of Problems
Investigation revealed that the abuse of antibiotics is a growing public health concern in Nigeria, as it is contributing to the emergence of antibiotic-resistant bacteria, which threatens the effective treatment of infectious diseases. Many Nigerians have easy access to antibiotics without prescriptions, leading to self-medication, misuse, and inappropriate dosing (Okeke et al., 2005; Olayinka et al., 2020).
Healthcare providers are also facing challenges, as frequent exposure to resistant infections complicates clinical management and increases the burden on health facilities. The lack of strict regulations on antibiotic sales and the weak enforcement of existing policies further exacerbate the problem, making it difficult to curb misuse effectively (Fadare et al., 2016).
Furthermore, many individuals stop antibiotic treatment once symptoms subside, share leftover antibiotics with family or friends, or use antibiotics for viral infections where they are ineffective (Auta et al., 2012). Such practices is heightening the prevalence of multidrug-resistant infections, which is now a critical threat to both individual and community health. It is against this backdrop that this study seeks to investigate the extent of antibiotic abuse in Nigeria, its health implications on the population, and the strategies required to mitigate its harmful effects.
1.4 Aim and Objectives of the Study
The aim of this study is to assess the impact of antibiotic abuse on the health of Nigerians and to identify measures for its effective control.
The specific objectives of this study include:
- To assess the role of regulatory authorities and healthcare providers in controlling antibiotic abuse.
- To identify the common patterns of antibiotic misuse among Nigerians.
- To examine the effects of antibiotic abuse on individual and public health.
- To investigate the socio-economic and behavioral factors that influence antibiotic misuse.
- To propose strategies to mitigate the adverse effects of antibiotic misuse in Nigeria.
1.5 Research Questions
Based on the stated objectives, the study will address the following research questions:
- What are the common patterns of antibiotic misuse among Nigerians?
- What are the effects of antibiotic abuse on individual and public health?
- Which socio-economic and behavioral factors influence the misuse of antibiotics in Nigeria?
- What is the role of regulatory authorities and healthcare providers in controlling antibiotic misuse?
- What strategies can be implemented to reduce the adverse effects of antibiotic abuse in Nigeria?
1.6 Significance of the Study
The outcome from the findings of this research will hold significant relevance in the following ways.
- The study will help healthcare providers adopt best practices in prescribing and counseling on antibiotic use.
- The research will support policymakers and regulatory agencies in formulating and enforcing effective antibiotic control measures.
- The study will benefit researchers by providing empirical data on antibiotic misuse and its health effects.
- The research will guide pharmaceutical companies and pharmacists to improve dispensing practices in line with national standards.
