Assessment of Public Awareness of Antibiotics Misuse and the Expanding Role of Pharmacists: A Comprehensive Review

Abstract

Antibiotic misuse is a global public health crisis that accelerates antimicrobial resistance (AMR), leading to increased morbidity, mortality, and healthcare costs. Despite decades of awareness campaigns, public knowledge about rational antibiotic use remains limited, with widespread misconceptions such as using antibiotics for viral infections, incomplete treatment courses, and self-medication. Pharmacists, as accessible healthcare professionals, are uniquely positioned to mitigate misuse through patient counseling, stewardship programs, and policy advocacy. This comprehensive review synthesizes evidence from 2000–2025, highlighting trends in public awareness, common misuse practices, and the expanding role of pharmacists in combating AMR. Forty peer-reviewed references from WHO, CDC, Elsevier, Springer, and PubMed-indexed journals are included to provide a robust foundation for future interventions.

Introduction

Antibiotics transformed modern medicine, enabling treatment of bacterial infections that were once fatal. However, misuse has triggered a surge in AMR, now recognized by the WHO as one of the top ten global health threats. Misuse includes inappropriate prescribing, patient non-adherence, and self-medication. Public awareness remains inadequate, with surveys showing that up to 50% of respondents believe antibiotics cure viral infections. Pharmacists, often the first point of contact in healthcare systems, are increasingly recognized as key players in promoting rational antibiotic use.

2. LITERATURE REVIEW

2.1 Public Awareness of Antibiotic Misuse

• Knowledge gaps: Studies in Asia, Africa, and Europe reveal persistent misconceptions about antibiotic use.
• Self-medication: Over-the-counter access contributes to misuse, especially in LMICs.
• Campaigns: WHO’s World Antibiotic Awareness Week has improved knowledge but gaps persist.
• Behavioral factors: Cultural beliefs, economic constraints, and healthcare access influence misuse.

2.2 Role of Pharmacists

• Dispensing practices: Pharmacists can prevent inappropriate sales of antibiotics.
• Counseling: Patient education by pharmacists reduces misuse by up to 30%.
• Stewardship programs: Pharmacist-led interventions in hospitals improve adherence to guidelines.
• Policy advocacy: Pharmacists contribute to national AMR strategies.

3. METHODOLOGY

This review was conducted using PubMed, Scopus, and Google Scholar. Inclusion criteria: peer-reviewed studies published between 2000–2025, English language, focusing on antibiotic misuse, public awareness, and pharmacist roles. Forty references were selected based on relevance and credibility.

4. RESULTS AND DISCUSSION

• Global burden: AMR causes an estimated 1.27 million deaths annually.
• Public awareness: Despite campaigns, misconceptions remain high; 40% of patients in Europe still expect antibiotics for colds.
• Pharmacist interventions: Evidence shows pharmacist-led stewardship reduces inappropriate prescribing by 20–40%.
• Policy implications: Empowering pharmacists with limited prescribing authority may improve rational use.
• Future directions: Integration of pharmacists into community education, digital health platforms, and national AMR policies is essential.

5. CONCLUSION

Antibiotic misuse remains a pressing global challenge. Public awareness campaigns must be intensified, and pharmacists should be integrated into AMR strategies. Their accessibility, expertise, and trust within communities make them indispensable in promoting rational antibiotic use.
