My son is 5 years old and has been on Sigulair since he was probably 2 years old. I never really thought anything of his behavior until recently. I took him to the doctor because he would not stop sniffing and said his nose felt stuffed up. The Dr. said his nose was completely clear. I asked her about the Singulair and she said I was the 2nd one this week whose child had recently developed a tic and that the other child was also on Singulair. She said she would call the Drug Rep. and let me know. By the time I got home she had called and I called her back. She said that tics occurred in a very small percentage of children taking singulair and to go ahead a stop taking it. I have also experienced severe behavioral problems ( tantrums unlike anything I have ever seen, telling myself and and my husband that he hates us, he tells us that he is stupid and that he doesn't love himself, he says he will cut his Dad's head off and that he wants us to go to jail.) There is more but just talking about for the first time, I am so upset that I never put 2&2 together. He has also had the leg pains and stomach pains. Everything I have read, fits my 5 year old to a"T". I am in awe over all of this. Today is his first day not taking it and I am looking forward to seeing some changes in him. Does anybody know if there are any long-term affects? Thank you to everyone who is open enough to talk about things and get information out there for people like me . I will never give my child Singulair again. Thank you so much
