What is croup?
Croup is a respiratory infection. It causes your throat and upper airways to swell and narrow. It is also called laryngotracheobronchitis. Croup is more common in children, but adults can also get it.
What causes croup?
Croup is commonly caused by a virus. It usually occurs during the common cold season. Croup is spread by breathing in germs from infected people when they cough or sneeze.
What are the signs and symptoms of croup?
Croup begins like a cold with cough, fever, and a runny nose. Your symptoms usually remain mild during the first 2 to 4 days. After that, the following symptoms get worse at night or when you lie down:
- A harsh or barking cough
- Noisy or whistling breathing
How is croup diagnosed?
Your healthcare provider will ask you about recent cold symptoms. He or she will listen to your lungs. Your healthcare provider may recommend a chest x-ray to make sure you have no other conditions.
How is croup treated?
Treatment can usually be done at home. Your healthcare provider may recommend any of the following:
- Medicines, such as acetaminophen, steroids, and NSAIDs, may be given. These medicines help decrease fever and inflammation, and open your airway. Ask your healthcare provider which cough medicine may help with your cough.
- Rest and keep calm as much as possible. Stress hormones can make your cough worse.
- Sit in a steam-filled bathroom. Turn the shower or bathtub on. Close the door and sit in the bathroom for about 15 to 20 minutes. Do not get into the shower.
- Use a humidifier or vaporizer next to your bed to help decrease your cough at night.
- Drink warm liquids. Warm liquids will soothe your throat and help with your cough.
The following list of medications are in some way related to or used in the treatment of this condition.
How can I prevent the spread of croup?
- Wash your hands often with soap and water. Carry germ-killing hand lotion or gel with you. You can use the lotion or gel to clean your hands when soap and water are not available.
- Cover your mouth when you sneeze or cough. Sneeze and cough into a tissue or the bend of your arm. If you use a tissue, throw it away immediately and wash your hands.
- Do not share cups, silverware, or dishes with others.
- Stay home if you are sick.
Call your local emergency number (911 in the US) if:
- You have severe trouble breathing.
When should I seek immediate care?

When should I call my doctor?
