My son is now 31/2 years old and has been on Singulair since he was about 1 Yr. old. His pediatrician recommended this due to his allergies and runny nose. He has had fluid on his ears since age 1, at least that we had confirmed, and she thought that the Singulair combined with another type of antihistamine could dry up the dripping nose and clear up the ears. It did not clear up the ears, but it does stop the drip. He had tubes placed in his ears a year ago in May of 2007 and is looking now at his second set coming up in Mid-October of 2008. He has been taking this medication all but one summer of his short life. My husband and I have both had children, he a boy and I a girl, both 14 years old now. In comparison to the other two, our little one has been so completely different to raise. I've always seen children of "other parents" that have discipline problems with their children and wondered what might cause that type of action in such a small child. Now we have this beautiful little boy, but all we've ever known is how difficult he is to handle and how is anger, temper tantrums and stubborness have always put a damper on outings and even casual days at home. Due to the fluid on his ears, his speach was delayed and he has now really began to speak like a normal 3 year old. I have noticed within the last 2 weeks how he has really started saying things that I have not approved of, but have fluffed it off thinking that he has heard other children in his pre-school say these things, or heard it on a superhero show. Something happened today that really made me stop and think. I picked him up at pre-school like normal after work and he would not come to me. He looked slightly glazed in the eyes, totally not like himself at all. He talked very little on our 30 minute commute home, which was not like him. He said, "I hate you and you don't like me". I told him I do love him and he said, "NO". He said, "I'm bad for you and I have a dangerous heart". He then told me, "I kill you". This was so disturbing that I told my mother what he had said. She told me that it sounds so much like what she had heard on the news that I should check it out. This is how I've come to find this site. We have stopped giving this medication to our son and I am curious to see if there will be any change in his personality. Tubes will probably be placed in his ears again despite whether his nose drips again, so that is a mute issue at this point. When we voiced our concerns to his pediatrician when the information first surfaced several months ago regarding adult behavior and side effects of Singulair, she fluffed it off and told us she has many young patients on this medication with no adverse side effects. He is taking Pediox every 12 hours. I am worried that we may need a substitute med, but we have tried so many that haven't worked. He has Albuterol Inhaler and Xopenex Inhaler when his Asthma symptoms kick in, when his allergies are at his worst. He has had pnumonia 2 times, or one like run of it I should say. It's important to keep his allergies under control so he doesn't get something like this again, but his overall mental health and stability cannot be jeopardized. Since his brain has been developing on this medication for 2 and a half years, does anyone know if this has lasting effects? He is very active and has a very short attention span. He can however sit through an entire movie if it is something that he likes and he has nothing better he wants to do at home. I do not believe he is hyperactive or ADHD in the sense that he needs medication for that symptom. He can be a very loving child and he is very polite and knows his manners. He comes from a very loving home with loving siblings. We have wondered for so long how he could possibly have turned out this way, and I am truly scared to think that this medication could be the cause of so much turmoil in our lives. I will be monitoring his results.
