My 13 year old daughter was diagonosed with asthma about 5-6 months ago. She was then prescribed singulair along with 250/50 Advair. Not even thinking about the meds being a problem my daughter has turned into a terror. The school has called a few times about behavior problems in school. Her grades are also dropping drastically. She has never had any kind of problems like this before. She is very angry, depressed,with many mood swings. I know that she is 13 but this is not normal. Her teacher reccommends she seek counseling as I agreed. Then I thought of this medication and wondered could this be the root of the problem? I called the doctor and he told me to take her off of singulair and see if I notice any difference in a week. It has only been 2 days so I guess we will see. This is really beginning to worry me. I want my daughter back.. If anyone has anything to share please email me at ****** Thanks, Cindi
