Antibiotics are medicines used to treat bacterial infections by killing bacteria or preventing their growth. They are highly effective when used correctly but do not work against viral infections such as the common cold, influenza, or most sore throats.

Antibiotics should only be taken when prescribed by a qualified healthcare professional. Using antibiotics unnecessarily or taking someone else’s medication increases the risk of antibiotic resistance, making future bacterial infections more difficult to treat.

Always follow the prescribed dosage, timing, and duration of treatment, even if you start feeling better before finishing the course. Stopping treatment too early may allow some bacteria to survive and multiply, increasing the chance of the infection returning.

Store antibiotics according to the instructions on the packaging. Most tablets and capsules should be kept in a cool, dry place, while some liquid antibiotics require refrigeration after preparation. Never keep leftover antibiotics for future illnesses, and always dispose of unused medication responsibly through a pharmacy if possible.
