In the hospital, the provider will help your child breathe better using different treatments. These may include:

• Medicine given with a nebulizer
• Steroids given through a vein (IV)
• Oxygen given in a tent over a crib or through a mask or a tube near the nose
• IV fluids, in case of dehydration
• Antibiotics (rarely)

Once your child starts breathing comfortably and your provider thinks it is safe, you will be able to take your child home. It may take a few hours in an emergency room before your child can safely be discharged. Sometimes an overnight stay in the hospital may be needed.

Croup symptoms usually last for up to 3 days but may continue up to 7 days.

Your child may continue to have these symptoms after leaving the hospital:

• Barking cough, especially during the night, but no breathing discomfort
• Hoarseness
• Fever
• Tiredness
• Restlessness

Follow the care instructions given by the provider before discharge, including the use of any medicines.

Steps you can take at home to manage symptoms and help your child feel more comfortable include:

• Expose your child to cool or moist air, such as cool night air or in a steamy bathroom. This may offer some breathing relief.
• Set up a cool air vaporizer or humidifier in the child's bedroom and use it at night.
• Keep your child upright to help make breathing easier. If your child is older than 1 year, you may use an extra pillow to prop up your child's head while sleeping.
• You may give your child acetaminophen or ibuprofen (for children older than 6 months) to lower a fever.
• Given plenty of warm fluids to soothe the throat and prevent dehydration.
• Try to keep your child as calm as possible. Crying can worsen symptoms and may cause breathing distress.
• Avoid cough medicines unless you discuss them with your child's provider first.

Contact your provider if your child is not responding to home treatment or is acting more irritable.

Call 911 or the local emergency number if your child has any of these symptoms:

• Trouble breathing
• Rapid shallow breathing
• Stridor, a high-pitched sound with each breath
• The muscles between the ribs pull inward when your child breathes
• Bluish color lips, face, or fingernails
• Drooling or trouble swallowing
• Extreme drowsiness
• Decreased consciousness
