My son is 8 y/o (almost 9). We love Singulair, he has been on it for years (at least 3 years). He can go about 4 days off of it and then his asthma flairs up again and we are up at night coughing. However after reading some of the posts I figure that I would throw in my two cents because some of these posts have been eye opening. We just recently went to an allergist and he was diagnoised with more severe ashtma then we expected so he was put on Allegra and Advair to go along with his Singulair and Albuterol (we dropped Claritan for the Allergra). In the last year my son has been experiancing horrible moods to the point that at 8 y/o I wonder if he knows what suicide is because the moods have brought him to a level that makes me very scared for him. We have recently decided to bring him to a therapist to talk about the moods and the behaviors he is experiancing at school and home. The negative attitude, the anger and frustration, the short temper, the night terrors, and night walking. He has also had over the last 6 months that 'stitch' in the side that another person was talking about. We took him to the ER once for it because we thought he was having an appendicitis attack. However he was not and we have had recent attacks like that. Like I said, I love Singulair, it was and sort of still is our dream drug however after reading this I wonder if it is not. My heart is crushed that a drug I thought was great for my son maybe the one thing that is hurting him. I am going to talk to his allergist about it and will try to take him off of it to see if it makes a improvement. Thank you so much for opening my eyes and maybe finding me a solution to it all.
