Coughing And Choking Constantly After An Asthma Flare-up, On Xoponex, Pulmicort. What Else To Do ?

My 3-year-old had an asthma flare-up about 5 weeks ago. Since then she has had these coughing/choking attacks every single night. A few times she has actually thrown up. She wakes up from her sleep coughing so hard that she can't breathe and you can hear her trying to clear the phlegm/mucus in her lungs/throat. She is on xoponex + pulmicort + xyrtec + singular + mucinex and now an antibiotic. I am thinking it might be pnemonia. Not sure what else to do. No wheezing or retraction and lungs sound clear as of last doctors appt on Wednesday.
