Delsym symptoms and conditions

Thanks for all these posts! My 4 year old daughter has a history of allergies which have in the past led to sinus infections and bronchitis. We used Xopenex and Pulmicort with the nebulizer along with Vazobid and Delsym and cleared up the bronchitis during Christmas 2007, but her pediatrician suggested her taking Singulair as a preventive medication for her allergies. This medication has turned our household upside down. She has taken it every night for 3 weeks and the side effects are the same as others have posted.......aggressive behavior, severe defiance to simple tasks, nightmares, stomach cramps, wetting accident at school (first time ever), weight gain, bruising, and vomiting. When told "no" she replies with wanting to kick me and tells me she doesn't want me as a mom anymore. The devilish behavior is intolerable. She was never like this before she started taking Singulair, and I am so thankful that I found this website quickly enough to put 2 and 2 together, and I am taking her off of it TODAY!!!
