My son just arrived back from a five week trip to shanghai. he is congested, and has a horrible cough. the dr prescribed prednisone. is that correct?

Asthma?: Prednisone will relieve airway inflammation in a flare of asthma. Sometimes even in patients without a diagnosis of asthma, wheezing can develop as a result of bronchitis, and prednisone can help ease breathing in this context. It will not treat the underlying cause of a respiratory infection which is usually a virus, and only time, rest and proper support/self-care treats viral bronchitis.
