Zirtec symptoms and conditions

I am a grandma to a 41/2 year old boy named Trevor. He has been on Singulair since he was 18mos. old. I am here to tell I am furious and heartsick to think that he has been subjected to a medication that can do the things it has done to him. I have NO DOUBT that Singulair is the problem. Our daughter and son-in-law have been at their wits end with
him and was one phone call away from taking him to a therapist (they needed one too!) The phone call to me on Monday, July 28th, was out of
sheer desperation. My daughter wanted me to look up the side effects for Zirtec. After looking that up and not finding anything I happened to remember that Trevor was also on Singulair. The actual side effects listed
didn't ring any warning bells with me. Somehow I happened onto this website and OH MY GOSH I flipped out and cried through every letter written by parents with the same side effects Trevor has. The compulsion, anxiety, anger and (heaven forbid) the threats of wanting himself, or someone he loves very much to die.This is absolutely unheard of for someone his age. I'm ever so thankful I found this website. Trevor was taken off Singulair that very day and within 3 days we had the sweetest,
most normal 4yr. old, on this earth. When I think what could have happened
had he stayed on it any longer...I can't!!!
