I already had experienced some bad side effects due to singulair with my daughter. She had become moody, emotional, having nightmares and those are just a few to mention. However, my son had no side effects. When I went to my children's pediatrician, she agreed some children do experience some side effects like my daughter was having. But somehow she didn't see it as quite a concern. I vowed then and there to take both my children off it. Then my son continued having his allergies and over the counter zyrtec didn't seem to help him. I went back to the dr. and because I trust her and have known her for many years....she convinced my to put him back on singulair since he had never had any previous side effects. Well, its been maybe 2 months and now I see my son acting strange. He is not himself. The normal activities he used to enjoy don't interest him anymore. For the last few days, he has been wanting to lay down and he says he's sleepy. To me, he is acting like someone who is depressed and he's only 5!!!!!! I am taking him back to the dr. and taking him off this horrible drug! For all you parents out there...I think we should all go with our "motherly" instincts and do what we think is best for our children. We are the ones that know our children on a day to day basis..not the doctor's. So I am kicking myself for not sticking to my original instincts. My daughter improved drastically! Even her teacher noticed a difference. Please if you notice something, take action before the drug does more damage.
