Croup in Children
Medically reviewed by Drugs.com. Last updated on Apr 6, 2025.
What is croup?
Croup is a respiratory infection. It causes your child's throat and upper airways to swell and narrow. It is also called laryngotracheobronchitis. Croup is most common in children ages 6 months to 3 years. Your child may get croup more than once.
What increases my child's risk for 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. Croup can also spread if your child touches contaminated items and then touches his or her mouth, nose, or eyes.
What are the signs and symptoms of croup?
Croup begins like a cold with cough, fever, and a runny nose. As your child's airway becomes swollen, he or she may have any of the following:
- Barking cough that is worse at night
- Noisy, fast, or difficult breathing
- Hoarse or raspy voice
How is croup treated?
Treatment can usually be done at home. Your child's healthcare provider may recommend any of the following:
- Medicines, such as acetaminophen, steroids, and NSAIDs, may be recommended. These medicines help decrease fever and inflammation, and open your child's airway. Ask your child's healthcare provider which cough medicine may help with your child's cough.
- Help your child rest and keep calm as much as possible. Stress can make your child's cough worse.
- Moist air may help your child breathe easier and decrease his or her cough. Take your child outside for 5 minutes if it is humid. Or, take your child into the bathroom and turn on a hot shower or bathtub. Do not put your child into the shower or bathtub. Sit with your child in the warm, moist air for 15 to 20 minutes.
- Use a cool mist humidifier to increase air moisture in your home. This may make it easier for your child to breathe and help decrease his or her cough.
