6 yo has bronchitis. Just gave him albuterol in nebulizer and his cough is really bad after treatment. It sounds productive though. Is this normal?

It is normal to. cough more right after a nebulization treatment. The medication loosens up the mucous in the airway passages. However, if he is wheezing more or having difficulty breathing, or he seems to need a treatment in less than 2 hours, you should call his pediatrician. He may need to be re-checked and/or his medications adjusted.
