My 7 year old, active and happy, son began taking this drug in January 2007 and hasn't been the same since. He had the following side effects: fever(nonstop unless on Motrin), diarreah, depression, rashes, nightmares, hallucinations and uncountable days missed at school. We thought it was a virus or flu and even had bloodwork done to see if it was something much more serious. When asked by our family doctor about why he was so sad he didn't know why, and when asked if he ever wished he was dead he responded with "yes sometimes". We were devestated and had not researched this drug until today. We took him off the Singulair on our asthma "specialist" advice to see if this would stop the fever and instead it stopped all the symptoms. Two days ago we started it again to be sure this was what was wrong and almost immediatly we had the same symptoms as described above. I will NEVER give this drug to my son and tell every parent I can not to either. This could have taken our childs life due to poor research on our part and doctors not making us aware, even when we were crying out for help, when they prescribe these lethal drugs. Any parent who reads this please monitor your childs behavior if you choose to give them this or any drug that you are not familiar with. I'm grateful for websites like this that help us understand and see what some modern medicine is capable of. Thank you to everyone who sent their side effects in it may have saved my childs life.
