Always finish your antibiotics? Longer is better? Outdated ideas about antibiotics are common, study says
"Always finish your antibiotics" is no longer considered medical best practice for all conditions. Surprised? You're not alone.
A new study reveals that most Americans believe it is always best to complete the full course of antibiotics, even when they feel better— a belief that aligns with long-standing but now outdated health campaigns. However, the reality is more nuanced. Depending on the situation, shorter or longer courses of antibiotics may be safer and more effective.
Dr. Alistair Thorpe, a research assistant professor at the University of Utah Health, explains that while major health organizations previously recommended always finishing the antibiotic course, recent evidence suggests this is not a one-size-fits-all approach. In fact, shorter antibiotic courses may be just as effective and safe as longer ones for many infections.
In the study, which surveyed 1,475 people across the country, 88% of respondents agreed with the common mantra to "always finish your antibiotic course." Moreover, about 60% of people preferred taking a longer course of antibiotics for pneumonia, despite current guidelines recommending shorter courses.
This preference for longer courses is often driven by the belief that they must "always finish" their antibiotic course, as suggested by 88% of respondents. The misconception stems from both clinician advice and public health campaigns.
However, the study highlights that this is not universally true. For many common infections, shorter courses of antibiotics are equally effective and carry fewer side effects than longer courses. Some infections, such as tuberculosis, may require longer treatment durations.
To address this misinformation, the authors suggest that doctors and public health campaigns should employ evidence-based strategies to communicate the complexities of antibiotic course length. This includes avoiding overly simplistic claims and acknowledging that health recommendations can evolve as new scientific evidence emerges.
Thorpe advises patients to have an open conversation with their doctors about the appropriate course length and adherence plan specific to their situation. Open communication with a clinician is crucial to ensure the most appropriate treatment plan is followed.
The changing recommendations regarding antibiotic use reflect the growing body of evidence and evolving clinical guidance. This is a positive development, indicating that the medical community is continually working to improve care by refining antibiotic usage practices.
