My son has had asthma and allergies since he was a newborn, thanks to and undiagnosed RSV infection that led to him being in an oxygen tent for 5 days. Since that time we have had him on several different medications to control it. Mostly, just albuteral through a nebulizer. Controlloing it this way worked for a while but eventually we put him on singulair. My son who was always the smallest boy in class went to being the heaviest. He also had terrible nightmares about his teacher and really bad cramps and pins and needles in his legs and feet upon waking EVERY DAY. He even began walking funny because of it. He had stomach cramps and diarrhea. His grades were awful all of a sudden and nothing could keep his attention. He went from being an easygoing easy to please child to being aggravated by the slightest thing. He was always getting in fights with other kids. He thought noone liked him and he began not liking himself. I took hm to a hypnotherapist to try to ontrol his anger but that did not help. NEVER in a million years did I ever think it was Singulair until I heard about someone else having the same experiences. Needless to say I have stopped giving him his singulair and in only three days have already seen my easygoing son coming back. Hopefully his side effects will completely go away.
