What impact does over-prescribing of antibiotics have on public health?

The over-prescribing of antibiotics plays a significant role in public health, particularly by contributing to the emergence of antibiotic-resistant infections. When antibiotics are used excessively, especially when they are not necessary, it creates an environment in which bacteria are frequently exposed to these drugs. This exposure can lead to mutations within bacterial populations that confer resistance to the antibiotics, making infections harder to treat.

As resistant strains become more prevalent, common infections that were once easily curable can become serious health threats. This scenario creates a cycle of increasing healthcare challenges, as both treatment options become limited and higher levels of drug resistance put pressure on healthcare systems. Additionally, the emergence of antibiotic resistance is linked to increased morbidity, mortality, and healthcare costs, as well as longer hospital stays and the need for more complex treatments.

In summary, the over-prescribing of antibiotics undermines the effectiveness of these crucial medications, leading to public health crises characterized by difficult-to-treat infections and increased health risks for the population.
