Most cases of croup can be safely managed at home, but call your health care provider for guidance, even in the middle of the night.
Cool or moist air might bring relief. You might first try bringing the child into a steamy bathroom or outside into the cool night air. If you have a cool air vaporizer, set it up in the child's bedroom and use it for the next few nights.
Acetaminophen can make the child more comfortable and lower a fever, lessening his or her breathing needs. Avoid cough medicines unless you discuss them with your doctor first.
You may want your child to be seen. Steroid medicines can be very effective at promptly relieving the symptoms of croup. Medicated aerosol treatments, if necessary, are also powerful.
Serious illness requires hospitalization. Increasing or persistent breathing difficulty, fatigue, bluish coloration of the skin, or dehydration indicates the need for medical attention or hospitalization.
Medications are used to help reduce upper airway swelling. This may include aerosolized racemic epinephrine, corticosteroids taken by mouth, such as dexamethasone and prednisone, and inhaled or injected forms of other corticosteroids. Oxygen and humidity may be provided in an oxygen tent placed over a crib. A bacterial infection requires antibiotic therapy.
Increasing obstruction of the airway requires intubation (placing a tube through the nose or mouth through the larynx into the main air passage to the lungs). Intravenous fluids are given for dehydration. In some cases, corticosteroids are prescribed.
