My son has been on singulair for 4 months now to control his asthma. It has done wonders in doing what it was intended to do, however, he's experiencing all of the side effects that the other parents are listing on this site. I threw his singulair in the trash a few nights ago after my son had a complete emotional melt down; which I could easily see he had absolutely no control over. I knew the drugs were changing his personality a bit, but I thought it was just the price we had to pay to keep him out of the hospital. My gut told me never to give him the meds because I had heard about the suicidal tendencies associated with the drug, I just knew I had to watch my son closely (plus he's only 3). I have 3 boys, and the one with asthma is my mild mannered, never gets in trouble, as close to perfect as a child can be. He's been saying "poop" and "pee" uncontrollably along with aggressive behavior toward his brothers and he would cry for no reason at all. His sleep patterns had changed as well, which I now know are due to nightmares - I even found him hiding under his bed a couple of times. I do not know why this drug is approved for children, but after reading the other stories I realize this seems to be the standard instead of the exception. I hope they pull this drug off the market before any more kids get hurt. I feel like I have poisoned my child - I will definitely be spreading the word on this. Anxiously awaiting for this medicine to leave my sons body so I can have my sweet little boy back.
