Abstract
Antibiotic resistance raises ethical issues due to the severe and inequitably distributed consequences caused by individual actions and policies.
Synthesis of ethical, scientific and clinical literature.
Ethical analyses have focused on the moral responsibilities of patients to complete antibiotic courses, resistance as a tragedy of the commons and attempts to limit use through antibiotic stewardship.
Each of these analyses has significant limitations and can result in self-defeating or overly narrow implications for policy.
More complex analyses focus on ethical implications of ubiquitous asymptomatic carriage of resistant bacteria, non-linear outcomes within and between patients over time and global variation in resistant disease burdens.
Neglected topics include the harms of antibiotic use, including off-target effects on the human microbiome, and the lack of evidence guiding most antibiotic prescription decisions.
