I only had to read a few to see the description of my 4 year old daughter, who has been on this med for about a year. My husband and I just had a talk last week about her bx and how that she cried off and on all day one day, and has high anxiety. She is very emotional but not constant and sometimes does not seem to have control of herself. I was considering taking her in to the doctor. Now I am going to try taking her off of this med. When we started her on it she had missed weeks of pre school for asthma/coughing symptoms. She is on it and pulmicort and zyrtec. She is doing well health wise, but her bx is getting increasingly worse. We will be stopping the singular tonight. It is scary to read all of the other notes from parents, and realize that this med may have caused her recent bx. I hope that we have not caused permanent side effects.
