Impact of Prescription Drug Misuse Education on Safe Prescription Medicine Practices among University Students in Nigeria

Abstract

Prescription drug misuse is an important public health concern among university students in Nigeria because some students may use prescription medicines without appropriate medical guidance, use medicines prescribed for another person, take higher or more frequent doses than directed, share medicines with peers, combine medicines with alcohol or other substances, or use prescription medicines for purposes other than their intended therapeutic use. Such practices may increase the risk of adverse drug reactions, drug interactions, dependence, overdose, treatment failure, and other health complications. University students may be exposed to prescription drug misuse through peer influence, academic and social pressures, self-medication, online information, informal medicine sources, and easy access to medicines. Limited knowledge of appropriate prescription medicine use and the risks associated with misuse may contribute to unsafe practices. Prescription drug misuse education provides an opportunity to improve students' understanding of medicine safety, appropriate prescription use, potential risks of misuse, and responsible healthcare-seeking. Against this background, this study investigates the impact of prescription drug misuse education on safe prescription medicine practices among university students in Nigeria. The study will be anchored on the Health Belief Model, Theory of Planned Behavior, and Social Cognitive Theory. The Health Belief Model explains how students' perceptions of susceptibility to medicine-related harm, perceived severity of adverse consequences, perceived benefits of safe medicine use, perceived barriers, and cues to action may influence prescription medicine practices. The Theory of Planned Behavior emphasizes attitudes, subjective norms, perceived behavioural control, and behavioural intentions in shaping students' decisions regarding prescription medicine use. Social Cognitive Theory emphasizes observational learning, peer influence, self-efficacy, reinforcement, and environmental factors in developing responsible medicine-use practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how prescription drug misuse education may influence safe prescription medicine practices among university students in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise undergraduate and postgraduate students aged 18 years and above enrolled in selected public and private universities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, universities, faculties or departments, levels of study, and eligible students. Prescription drug misuse education will be assessed using indicators such as exposure to educational sessions, frequency and duration of education, information on appropriate prescription use, risks of self-medication, dangers of using another person's prescription, dose adherence, medicine sharing, medicine storage, risks of combining prescription medicines with alcohol or other substances, potential drug interactions, dependence and misuse risks, recognition of adverse drug reactions, and appropriate healthcare-seeking. Safe prescription medicine practices will be assessed using indicators such as using medicines only as prescribed or appropriately advised by qualified healthcare professionals, taking medicines according to prescribed dosage and timing, avoiding the use of another person's prescription, avoiding unnecessary medicine sharing, avoiding inappropriate dose modification, checking medicine instructions, informing healthcare professionals about other medicines being used, avoiding unsafe medicine combinations, observing expiry dates and storage requirements, completing prescribed treatment where appropriate, and seeking professional advice when adverse effects or uncertainties occur. Data will be collected using structured questionnaires, standardized medicine-use knowledge and practice assessment tools, scenario-based prescription medicine safety questions, and relevant university health-centre records where available. Descriptive statistics will be used to summarize students' characteristics, prescription medicine-use patterns, sources of medicine information, exposure to education, and safe medicine practices. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of prescription drug misuse education on safe prescription medicine practices. Where a quasi-experimental design is adopted, medicine-use practice scores before and after the educational intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that prescription drug misuse education has a significant positive impact on safe prescription medicine practices among university students in Nigeria. Students exposed to structured and practical prescription drug misuse education are expected to demonstrate safer medicine-use practices than students without comparable exposure. Education may improve students' understanding of the dangers of using medicines without appropriate professional guidance, sharing prescriptions, altering doses, combining medicines with alcohol or other substances, and obtaining prescription medicines from unreliable sources. Practical education may encourage students to follow dosage and administration instructions, check medicine labels, communicate openly with healthcare professionals, recognize adverse drug reactions, and seek professional advice before making changes to prescribed treatment. It may also strengthen students' ability to distinguish legitimate medicine information from unreliable online or peer-generated advice. However, peer influence, financial barriers to healthcare, easy access to medicines, self-medication culture, academic pressures, limited university health services, and misinformation may reduce the effectiveness of education alone. The study therefore expects accessible, evidence-based, practical, and sustained prescription drug misuse education, supported by appropriate university health services and medicine-safety policies, to contribute significantly to improved safe prescription medicine practices among university students in Nigeria. The study is expected to contribute to the literature on prescription drug misuse, medicine safety, rational medicine use, self-medication, university student health, pharmaceutical health education, substance-use prevention, pharmacovigilance, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Federal Ministry of Education, National Agency for Food and Drug Administration and Control, universities, university health centres, pharmacists, physicians, nurses, public health practitioners, student organizations, medicine-safety programmes, development partners, and policymakers regarding strategies for reducing unsafe prescription medicine use. The study will also provide evidence-based recommendations for integrating prescription medicine safety education into university health programmes, strengthening access to qualified healthcare professionals, improving student awareness of prescription medicine risks, promoting rational medicine use, strengthening medicine counselling services, and developing effective health communication strategies for preventing prescription drug misuse among university students across Nigeria.
