Antibiotics: What Everyone Should Know
Antibiotics are medicines that fight infections by either killing the bacteria or by making it difficult for the bacteria to grow and multiply. Antibiotics can save lives and are critical tools for treating certain bacterial infections, but they aren't always the answer when you're sick.
Overusing or misusing antibiotics can cause:
- Antimicrobial resistance – when antibiotics no longer work against bacteria. This can make infections harder to treat.
- Side effects that can range from mild (rash, nausea, diarrhea, yeast infections) to more serious like C. diff infections or severe allergic reactions.
Help prevent antibiotic resistance by only taking antibiotics when needed and by following your provider's instructions when taking them.
Antibiotics only treat certain infections caused by bacteria. Bacteria are germs that cause infections like strep throat and whooping cough.
Antibiotics do not treat infections caused by viruses. Viruses are germs that cause infections like RSV, flu, COVID-19 and the common cold.
