Background: Antibiotic resistance (ABR) is a critical global health threat, disproportionately affecting low- and middle-income countries (LMICs) where systemic constraints, economic pressures and sociocultural factors drive inappropriate antibiotic use. While quantitative studies describe prevalence patterns, they fail to capture the underlying motivations and contextual barriers influencing prescribing and dispensing behaviors. This systematic review synthesizes qualitative evidence on the perceptions of healthcare professionals, patients, and caregivers regarding antibiotic use and explores the barriers and facilitators for implementing antibiotic stewardship programs in LMIC healthcare settings. Methods: We conducted a systematic review following PRISMA 2020 guidelines, based on a registered protocol in PROSPERO ID: CRD42024583749. Searches were performed in Medline, Embase, Cochrane Library, Web of Science, and Google Scholar for English-language studies published between 2014 and 2024. Qualitative and mixed-method studies examining stakeholder perspectives on antibiotic use and antibiotic stewardship implementation in LMICs were included. Studies were excluded if they focused exclusively on pediatric or neonatal populations, veterinary medicine, or quantitative outcomes without qualitative components. The data were analyzed using thematic analysis to identify and categorize codes and identify themes following methodological quality assessment of included studies using the Critical Appraisal Skills Programme Qualitative Studies Checklist by two independent reviewers. Results: Out of 2214 studies screened, a total of 119 studies from 33 LMICs were included, encompassing over 4000 participants across hospital, primary care, and community settings. Five interlinked themes emerged: (1) antibiotic use as a pragmatic response to diagnostic uncertainty and resource constraints; (2) financial and commercial drivers shaping prescribing and dispensing practices; (3) the disconnect between knowledge, sociocultural norms, and clinical behavior; (4) multi-level structural and professional barriers to antibiotic stewardship implementation; and (5) the critical role of health system vulnerabilities in perpetuating misuse. Conclusions: Inappropriate antibiotic use in LMICs reflects rational adaptations to systemic limitations rather than isolated knowledge gaps. Effective ABS strategies must address structural deficiencies, economic incentives, and sociocultural norms, while integrating context-specific interventions that strengthen health systems and engage all levels of care. The findings should, however, be evaluated in light of the geographic unevenness of the evidence base, the exclusion of non-English and gray literature, and lack of certainty assessments for synthesized themes.
