Legends, dogmas, presumptions, and demystifications in antibiotic therapy.

Suboptimal antimicrobial use is a global challenge driven by entrenched misconceptions and dogmas. This article aims to critically evaluate and debunk several widespread myths in infectious disease management that lead to overdiagnosis and overtreatment. Through a nonsystematic literature review, this manuscript examines key misconceptions across various aspects of antimicrobial therapy, including administration routes, drug mechanisms, treatment duration, and the interplay with infection source control. It also explores the influence of evolving concepts like long-acting antimicrobials and the human microbiome. We challenge the dogmas that intravenous antibiotics are superior to oral agents, that longer courses are always better, and that bactericidal drugs are more effective than bacteriostatic ones. The review highlights the paramount importance of source control and surgical intervention in treating severe infections and cautions against misinformation surrounding the human microbiome. The medical community must critically re-evaluate long-standing clinical practices to improve antibiotic stewardship. By debunking these myths, we can promote a more precise, safe, and effective approach to antimicrobial use, ultimately reducing unnecessary prescribing and combating antimicrobial resistance.
