We are yet another success story after taking our 3 1/2 year old son off of Singulair three weeks ago, and I have this website to thank for it. We put my son on Singulair approximately 1 year ago due to his asthma. While his asthma symptoms did get at least somewhat better, he complained of many of the side effects that have been listed on this website--tummy aches, itching for no reason, withdrawn, depressed, uncooperative, bruised easily, unexplained case of chronic hives, nightmares, and trouble falling and staying asleep though clearly exhausted. He also developed a dry cough over the course of six weeks or so that surfaced every few days, though he was not otherwise sick. I found this website when my husband suggested that the Singulair may be causing the cough. I had never connected all of his other symptoms until reading the stories about other children on Singulair. Prior to being on Singulair, my son was the most curious, outgoing and interactive child and I can't tell you how great it is to have him back to his old self. The most interesting thing to me is how another mom that knew my son before he started Singulair commented that she was so glad to see him back to his old self again. My mother has also noticed a huge difference in his behavoir and has commented numerous times that it is nice that he is back to his old self. Now that school is starting again and cold season is quickly approaching I, like others that have posted, am worried about what medication will control his asthma if he has not outgrown it. But . . . I'm willing to experiment with any alternatives to keep him off of Singulair. If anyone has suggestions for alternative medications, please share your insights with the rest of us.
