My son is 8 and has Autism. In the last two months he has been taking Singulair. In the last two months I have noticed him progressively getting very aggressive and unable to tolerate disappointments etc. He's been very whiney. It's to a point where he is out of control with his moods. He hauls off and hits me, other kids and adults. Like a monster has taken over. He can't seem to calm down and it's hard for him to tell me what is going on because of his Autism. He has never been this extreme and had such a long bout of horrible behavior. I forgot he had started this new medication for his allergy related asthma/wheezing. I did not figure it out but I am convinced this may have been the trigger for his uncontrollable behavior. We had a huge embarrassing incident today at camp where he ran into the school he was not suppose to be in, then came back and pushed this boy and attacked his Mom by pulling her arm nearly knocking her over, pinching her arm and squeezing it very hard! I was shocked at his behavior. Kicked and hit me and the counselor and squeezed my boob really hard,lifted my shirt up several times, just totally out of control. I had to lay on him practically to control him and I cried in shock and fear and wondered if this was my son! It took a long time to calm him down. He is going off the medication today and we are talking to several other doctors and going to a neurologist. He has sleepless nights too and dry mouth. Please watch out if you already have a child with issues. Worried and sad Mom!
