About This Course

Antibiotics are powerful medicines, but they are designed to treat only certain infections caused by bacteria. They do not cure viral illnesses such as the common cold, influenza, most sore throats or many cases of cough and diarrhoea. Taking antibiotics when they are unnecessary can cause side effects and encourage bacteria to become resistant, making future infections harder to treat. This course explains how antibiotics work, why proper diagnosis matters and how to use prescribed medicines safely. It will help learners avoid self-medication, understand when antibiotics may be needed and know when to seek advice from a qualified healthcare professional.
