My almost four year old son has been on singulair for a little over two years now and I am SICK to my stomach after reading all of these entries. Our son was such an amazing baby, he was very even tempered and behaved beautifully. After some chronic sinusitis and environmental related allergies he was placed on Singulair 15mg granule packets once/day. It was a gradual change in his behavior but very noticeable. Our wonderful child became very irritable, hipper, restless, moody, and overly sensitive, Our son went from sleeping trough the night to waking several times a night. We are lucky if we have a couple good nights a month. He has also been tougher to get to sleep at night he goes from 8am to midnight on most days (no naps) and will stumble and fall - and he will still protest sleep. On other days he is so hard to keep awake sometimes crashing after school, missing dinner, and going thought the night. He too like others has been complaining of leg cramps, but I just thought it was a tingly foot....after he would continue to walk around for hours limping, I just thought he was joking. But, the funny leg cramp would always make a reappearance.....and now this could be why???? He is very physical with us and his brother....always hitting and kicking intentionally. His behavior was only exacerbated by the recent birth of our 6 month old. My husband and I have been brought to tears and worn out by his extreme behavior. One moment he is happy - then aggressive or moody and brought to tears....he is like an emotional roller coaster. He always has a blast at pre-school but completely loses control and freaks out when it is time to go, he says he hates school and is miserable there, he cries so much he throws up. He also goes through hunger strikes, when he is so emotional he choses not to eat. It did not used to be like this! Coincidental or medical poisoning???? After reading all of these entries, there is no doubt in my mind that Singulair is the culprit. This drug should be recalled and the pharmaceutical company should be held liable and accountable for this. Our lives have been disturbed and our children's health compromised, what for....a PROFIT? The FDA needs to do more extensive testing on pharmaceutical drugs and implement more stringent guidelines. and the prescribing doctors shouldn't push these drugs so emphatically. As of last night we stopped the medication and are relying solely on the Zyrtec OTC. I pray for a change.....we miss the little boy we used to know :-(
