With the medication you have been prescribed by the doctor, it seems your baby must be having moderate severity of bronchial asthma
is just works as a broncho-dilator to dilate the smooth muscles of small airways but the accompanying inflammatory component needs to be taken care of by steroids
only. To use or not, depends upon the severity and duration of the symptoms and I personally advice you to see a pediatric Pulmonologist for your baby. Vomiting
is a part of the problem with cough in kids and is not due to the drugs. I believe you are giving these medication by nebulizer
as thro' oral route, it has less efficacy for brocho dilatation.
