Our daughter is 17. She started taking Singulair June of 2000, 8 yrs ago. Upon hearing the side effects I insisted she stop taking the drug due to the fact that she also showed extreme signs of agitation, irritation & was always angry & frustrated by everything & everyone around her. Her standard comment was " I know I'm mean & rude". As a parent you know your child & we knew something wasn't right but never suspecting this drug. She as a young child never exhibited any of these signs. She was evaluated by 2 psychiatrist in these past 8 yrs., ADD was one of the diagnosis & our concerns that there may be some bipolar symptoms. After taking her off the Singulair there has been an obvious improvement that is evident to all the family members. The Singulair did an outstanding job of helping with her allergies which are severe & also contributed to multiple sinus surgeries. But the trade off? We are absolutely convinced & she is too that the Singulair had a debilitating effect on her personality. She once again talks, laughs & is such a joy & pleasure to be around. I will add that she never felt any suicidal tendencies, but just severe agitation, irritation, impatience & her reactions to situations & people around her were completely out of balance. I will always be convinced given our experiences that Singulair was completely responsible for 8 yrs. of heartache for us as her parents & 8 yrs. of misery for her.
