Why must antibiotics be used judiciously in infection management?

The use of antibiotics must be judicious in infection management primarily to prevent the reduction of their effectiveness over time. This phenomenon, known as antibiotic resistance, occurs when bacteria evolve and adapt in response to the use of antibiotics, rendering these drugs less effective against infections they once treated effectively.

When antibiotics are overprescribed or misused, bacteria may develop resistance due to selective pressure. This means that the more frequently these medications are used, especially inappropriately, the more likely it is that resistant strains will emerge. As a result, common infections may become difficult or impossible to treat, leading to increased morbidity, prolonged hospital stays, and greater healthcare costs.

Maintaining the effectiveness of antibiotics is crucial to ensuring they remain a viable option for treating infections now and in the future. Therefore, judicious use not only preserves their effectiveness but also protects public health by preventing the spread of resistant bacterial strains.
