What can be a potential consequence of antibiotic misuse?

The potential consequence of antibiotic misuse leading to an increased risk of treatment failure is a significant concern in the realm of antimicrobial stewardship. When antibiotics are misused—whether through over-prescribing, inappropriate prescribing for viral infections, or not completing prescribed courses—the bacteria can develop resistance to these drugs. This resistance can result in previously treatable infections becoming harder, or even impossible, to treat effectively.

As bacteria evolve and adapt in response to the misuse of antibiotics, the effectiveness of these medications diminishes. In the case of treatment failure, patients may experience a worsening of their condition, extended illness duration, or even complications that could have been avoided with proper antibiotic use. In clinical practice, this emphasizes the importance of appropriate prescribing and adherence to guidelines to ensure antibiotics remain effective and that patients receive the best possible care.

The other potential outcomes listed do not align with the realities of antibiotic misuse. Improvement in public health typically arises from responsible antibiotic stewardship, while an increase in antibiotic resistance directly contradicts the idea of enhanced effectiveness of antibiotics.
