The rational use of antibiotics is crucial to avoid the development of bacterial resistance, ensure the long-term effectiveness of these medications, and prevent unwanted side effects.
When antibiotics are used too often or incorrectly, we give bacteria the chance to adapt. Some then become capable of resisting treatments: they become superbugs. Once resistant, these bacteria become difficult or impossible to fight with regular antibiotics, which seriously complicates the treatment of certain infections. This phenomenon is accelerated when antibiotics are taken without a valid medical reason, when the treatment is stopped too early (as soon as one feels better), or when the prescribed doses are not followed. As a result, in the end, even common infections can become dangerous, and medicine could gradually run out of effective solutions for diseases that were once simple to treat.
Taking antibiotics indiscriminately ultimately weakens health: infections that last longer, diseases that are difficult to cure, and more frequent medical complications. In short, when these medications are misused, the risk of encountering multidrug-resistant infections increases, meaning tough infections that do not respond easily to standard treatments. These situations can lead to longer hospitalizations, require heavier or toxic treatments, and seriously increase health risks, particularly for young children, the elderly, or those who are fragile. It's simple: when misused, antibiotics lose their effectiveness when they are truly needed, which seriously complicates medical care and exacerbates risks for everyone.
The human body is inhabited by an incredible amount of friendly bacteria that make up our microbiome. When you take antibiotics without really paying attention, it can wipe out a good portion of these nice bacteria. As a result, you end up with an imbalance also known as dysbiosis. And at that point, not-so-friendly bacteria can take advantage and take their place.
This kind of imbalance often results in annoying intestinal issues, both minor and major: diarrhea, abdominal pain, persistent digestive discomfort... In short, not great in terms of comfort. In some cases, it can even lead to infections from really troublesome bacteria like Clostridium difficile, which is responsible for severe diarrhea.
Disrupting this little ecosystem can also cause other problems that affect your overall health: a slightly less effective immune system, long-term digestive disturbances, or even various metabolic disorders. When you take care of your microbiome by using antibiotics only when absolutely necessary and under medical advice, you protect this precious flora that, in return, keeps you healthy.
Antibiotics consumed often end up in our wastewater, as wastewater treatment plants are not able to completely eliminate them. As a result, these molecules spread into rivers and soils, affecting natural ecosystems and disrupting aquatic life. For example, their presence in the environment can promote the emergence of resistant bacteria, which then circulate in soils, animals, and come back to us. This creates a vicious circle that is hard to stop. Sometimes, traces of antibiotics are even found in drinking water, in small quantities certainly, but the potential effects on our health are still poorly understood.
To avoid abusing antibiotics, one can already adopt a few simple reflexes, such as respecting the durations and dosages prescribed by your doctor (never stop your treatment too soon!). Self-medication is a no: an antibiotic effective against a specific infection will do absolutely nothing against another disease that seems similar. Also, thinking about vaccines is smart: fewer infections = less need for antibiotics. And why not prioritize certain natural or complementary approaches — of course, only on medical advice — such as consuming probiotics to strengthen your microbiome? Better to prevent than to cure!
Antibiotics do not work on viruses. Using them unnecessarily for common viral illnesses like colds or the flu only promotes bacterial resistance without improving your health.
The discovery of penicillin by Alexander Fleming, the first antibiotic used on a large scale, was purely accidental due to the contamination of a bacterial culture plate by mold.
A large majority of antibiotics consumed worldwide are not only used to treat humans but are also used in agriculture and livestock, significantly contributing to environmental contamination and the emergence of bacterial resistance.
Our gut microbiota contains nearly 100 trillion bacteria that actively contribute to our physical and mental health. Repeated courses of antibiotics can disrupt this fragile balance for the long term.
Adopting good personal hygiene, following recommended vaccinations, maintaining a balanced diet to strengthen immunity, and promptly consulting a healthcare professional in case of unusual symptoms can help reduce the risk of bacterial infections that require antibiotic treatment.
A misuse is often characterized by the use of antibiotics without a prescription, interruption of the prescribed treatment before the recommended end, taking expired antibiotics, or using antibiotics that were prescribed to someone else.
If you forget a dose, take the missed dose as soon as possible. However, do not take a double dose to make up for the missed one. If in doubt, consult your doctor or pharmacist for guidance on how to continue your treatment.
An imbalance of the microbiota (called dysbiosis) can lead to digestive disorders, increased susceptibility to infections, and a general weakening of the immune system. This condition is usually temporary but may sometimes require specific measures to restore intestinal balance.
Yes, certain natural approaches such as the use of probiotics to boost immunity or essential oils with antibacterial properties can be considered in certain situations. However, these alternatives do not systematically replace antibiotics and require prior medical advice.
Antibiotics are effective only against bacterial infections. Viral illnesses such as colds and the flu do not respond to antibiotics, and inappropriate use can promote the development of bacterial resistance.
