Think you need antibiotics for a chest cold? Think again.

If you've ever had a bad cough or chest cold, you may have wondered if antibiotics would help.

In most cases, they won't.

Acute bronchitis (sometimes called a chest cold) is usually caused by viruses, and antibiotics only work against bacterial infections. That's why health care providers often recommend rest and symptom relief instead of antibiotics.

Why not take antibiotics "just in case"?

Taking antibiotics when they aren't needed can:

• Cause side effects such as diarrhea, nausea, or allergic reactions
• Increase the risk of antibiotic-resistant bacteria, making future infections harder to treat
• Lead to unnecessary costs without helping you recover faster

Most people with acute bronchitis begin to feel better within a few weeks, although a cough may last longer.

When are antibiotics appropriate?

Your provider may prescribe antibiotics if they suspect a bacterial infection, such as pneumonia or whooping cough, or if you have certain chronic medical conditions that increase your risk for complications. Your provider will evaluate your symptoms and determine the best treatment for you.

What can you do instead?

Most viral respiratory infections improve with supportive care. To help you feel better:

• Get plenty of rest.
• Drink fluids.
• Use a cool-mist humidifier or breathe warm steam.
• Take over-the-counter medications for fever or discomfort, as recommended by your provider.
• Avoid smoking and secondhand smoke.

Contact your provider if you have difficulty breathing, a high or persistent fever, chest pain, symptoms lasting more than three weeks, or symptoms that continue to worsen.

Helping keep antibiotics working

Using antibiotics only when they are truly needed helps protect everyone by slowing the development of antibiotic-resistant bacteria. Choosing the right treatment helps you recover safely while preserving antibiotics for the times they are truly needed.

Not getting an antibiotic doesn't mean you're not getting the right care. It means you're receiving treatment based on the best available medical evidence.
