18 November 2025 is European Antibiotic Awareness Day

European Antibiotic Awareness Day is an annual event that reminds everyone of the value of antibiotics and the importance of using them only when necessary. It's a day to highlight that these lifesaving drugs are under threat from the growing problem of antibiotic resistance.

Antibiotics can cause more harm than good if taken unnecessarily. Antibiotics, like all medicines, have side effects. Take care of yourself and learn to treat common illnesses that do not require antibiotics.

Antibiotic resistance

Antibiotics are losing their effectiveness at a pace that was unforeseen even 5 years ago. Antibiotic resistance is caused by the overuse and misuse of antibiotics. It happens when bacteria or bugs becomes resistant to different types of antibiotics. These are sometimes called superbugs. Antibiotics that once worked well to treat an infection may no longer be as effective, or may not work at all.

Dr Paul Ryan explains what antibiotic resistance is and why it matters

Antibiotics and viral infections

Antibiotics are used to treat bacterial infections. They don’t work for viral illnesses including colds, flu, sore throat and COVID 19.

One of the best ways to avoid many viral infections is through vaccination, so keeping up to date with your vaccines really matters.
