If your child received Epinephrine to help him breathe, it may wear off 1-2 hours before the steroid starts to work. Dexamethasone (decadron) has been shown to be the best steroid for croup. Untreated croup tends to worsen for 3-5 days before it starts to improve (as do most viral infections). ...Read more

Postinfectious cough can last up to several weeks, and it can trigger brochospasm especially if the child has asthma. Croup can be complicated by pneumonia or pulmonary edema. It would be a good idea to take her to a pediatrician if her cough is severe. ...Read more

Croup is usually caused by a virus infection, most often a parainfluenza virus. After the third day of symptoms, a patient will begin to clinically improve.The cough may in itself represent a post-viral cough that may persist for weeks. ...Read more
