What are Antibiotics?

Antibiotics are special medicines that help us fight infections caused by bacteria. Bacteria are tiny living things that can make us sick, like when we have a sore throat or an ear infection. Antibiotics work by killing the bacteria or stopping them from growing.

Why are Antibiotics Important?

When we get sick from a bacterial infection, antibiotics can help us get better. They can prevent diseases from becoming more serious or spreading to others. For example, if you have a bacterial infection, your doctor might give you antibiotics to help your body fight it off.

How Do Antibiotics Work?

  1. Killing Bacteria: Some antibiotics kill bacteria directly. This means that when you take them, they attack and destroy the bacteria in your body.
  2. Stopping Growth: Other antibiotics don’t kill bacteria but stop them from multiplying. This gives your immune system a chance to catch up and eliminate the infection.

Types of Antibiotics

There are many types of antibiotics, and they are often divided into two main groups:

  • Broad-spectrum antibiotics: These work against a wide variety of bacteria.
  • Narrow-spectrum antibiotics: These are effective against specific types of bacteria.

Using Antibiotics Responsibly

  • Complete the Course: If a doctor prescribes antibiotics, it’s important to take them exactly as directed and finish the entire course, even if you feel better. This helps ensure all the bacteria are killed and reduces the risk of them coming back.
  • Don’t Share Antibiotics: Never share your antibiotics with someone else. Different infections require different treatments.
  • Antibiotic Resistance: If antibiotics are overused or misused, bacteria can become resistant. This means the antibiotics won’t work anymore. This is a serious problem because it can make infections harder to treat.

Tips to Remember

  • Always ask your doctor or pharmacist if you have questions about antibiotics.
  • Remember that antibiotics only work on bacterial infections, not viral infections like the common cold or flu.
  • Practice good hygiene, such as washing your hands frequently, to help prevent infections.
