Treatment
Most, though not all, cases of viral croup are mild. Breathing in moist air helps most kids feel better, and ibuprofen or acetaminophen (only in children over 6 months old) can make them more comfortable. As with most illnesses, rest and plenty of fluids are recommended.
The best way to expose your child to moist air is to use a cool-mist humidifier or run a hot shower to create a steam-filled bathroom where you can sit with your child for 10 minutes. Breathing in the mist will sometimes stop a child from severe coughing. In the cooler months, taking your child outside for a few minutes to breath in the cool air can ease symptoms. You also can try taking your child for a drive with the car windows slightly lowered.
Consider sleeping overnight in the same room with your child to provide close observation. If you cannot break your child's fast breathing and croupy cough, call your doctor or seek medical attention as soon as possible.
Medical professionals will evaluate your child if the croup appears serious or there is a suspicion of airway blockage. Doctors often treat croup with steroids to decrease airway swelling. For severe cases, doctors will give a breathing treatment that contains epinephrine (adrenalin). This reduces swelling in the airway quickly. Oxygen also might be given, and sometimes a child with croup will remain in the hospital overnight for observation.
