My daughter has a reliever inhaler for viral induced wheezing, but at the moment I am listening to her coughing and coughing in bed. Last time we saw the doctor she said that we could try using a steroid preventer inhaler. We were a bit reluctant because the doctor mentioned side effects, but her episodes of coughing and wheezing seem to be increasing in frequency and severity. Does anyone have a child of a similar age using a preventer inhaler?
