My son is 11 years old and my mother recently told me that Singulair can be linked to suicidal thoughts and actions. This is scary to me because my son has been taking Singulair for about three years now and I can clearly see a change in his mood. It seems like nothing makes him happy even activities that he use to love he is no longer interested in. He has become so negative and can never find the good in a situation. He rarely sleeps through out the night he complains of being hot and having bad dreams. He does very well academical in school but he does not like to participate in group activities. He had the same teacher for fifth grade that he had in third grade and his teacher mentioned to me that he is completely different and lacks motivation. I must admit even before I learned anything about the mood effect that Singulair could have on patients I was thinking of getting my son counseling to focus on anger management because it seems like the smallest thing agitates him. I don't know what to do now. I think I going to try herbal treatments at least they will be natural and hopeful lack side effects.
