Antibiotic

Antibiotics are powerful medicines that fight infections caused by bacteria. They work by either killing the bacteria or stopping them from multiplying. This allows your body's immune system to take over and clear the infection.

Here's a quick summary:

Targets: Bacteria, not viruses (common cold, flu)
Action: Kills or hinders bacterial growth
Benefits: Treats infections, saves lives
Important: Only take them when prescribed by a doctor, and finish the full course to prevent resistance.
