How To Prevent And Treat Croup
Humidifier

Dry air can make a throat more irritated and cause more coughing, which can inflame the airways further making the problem worse. A cool mist humidifier helps to keep moisture in the air and soothe the inflamed vocal cords. The humidifier also creates cool, soothing air for the child to help ease pain and help children relax.
Another method for getting moisture to the child and reducing airway irritation is to turn on a hot shower and let the room fill with steam. Allowing the child to sit in the room with the steam and breathe the warm, moist air can help break up mucus and create a more productive cough. This can help clear the airways and ease some of the symptoms.
Steroids

If the fever gets really high, or if the airway becomes overly obstructed, it is important to seek emergency care immediately. In addition, if croup lasts more than three to five days, or the child does not seem to respond to at-home treatments, it is a good idea to take them to the doctor. The doctor will evaluate the child and rule out any other issues. Often, the doctor will prescribe medication to help with a more severe case of croup.
Steroids, such as dexamethasone, can be very beneficial in treating croup symptoms. Dexamethasone can reduce inflammation and promote healing in children, the effects of which can often be felt within six hours of giving the steroid and can last up to seventy-two hours. Epinephrine can also be used to open airways quickly, but its effects are short.
