Singulair and fly

I am replying to my first post here yesterday....So today I didn't give my 3 yr old son the singulair and do not plan on it ever again! I have to say though...I am very very concerned. I think tonight I truly saw one of the bad behavioral side effects :( He got upset over something so small. Said he didn't love any of us, he didn't want Chinese which is his favorite! He didn't want to do any of the things that we gave him options on that he normally would jump right up to do! This devastated me! I right away thought to myself is this going to get worse before it gets better? He is still complaining of back pain which I know that will take some time. He punched a little boy just before dinner in the neck. He walked out of the neighbors house to go home and usually I have to carry him out. This is seriously scaring me! I'm not sure what to do ? My fiance, his father, doesn't understand and started to yell at him for his behavior. (We don't get much time to talk and when I try to his dad just says he is ok but I know, deep down he isn't) I am the one with him everyday at home taking care of him. I am now being more patient with this behavior when normally I would lose patience and punish him with time outs. Do I continue to do time outs?
Why should I punish him when its not all him ? This is so unfair :( I mean, he is a boy and yes he acts like one. Doesn't share at times, hits sometimes, he is a or was a normal 3 year old boy. His dad will follow my footsteps on this as he see's how I handle things but I'm a little witty on how to handle it now. At this point I am babying my baby! I will tell him when things he does is not right but I'm at the point now that I don't want to send him to preschool! Do I inform the teachers? Can someone give me some words? Its just hard because he is my oldest and is only 3 so not only am I learning to deal with regular behaviors, I now have to understand how to cope and deal with this until its over. Thank you in advance very much for any help and advice!!!!

My 12 year old son was diagnosed with severe infantile asthma at 4 months of age - it was so bad that we had to fly him from Illinois to the National Jewish Center in Denver, Colorado, for a correct diagnosis (I would highly recommend this center for anyone with asthma that is not controlled). He did well until about six months ago, when his asthma became uncontrolled. Our doctor put him on Singulair. My son has been having trouble at school, is at risk of being held back, and his shown behavior problems that he never had in the past. I never put it together - until I saw the news last week. He's now off Singulair and we've seen some improvement, and we're praying for more. Thank God we found out before it was too late...

Yes, my daughter is 17 and was on Singular for about 3 weeks. The Doctor prescribed it to her for allergies. She had asthma up till she was about 10 or so. No problems with Asthma since then. But last year when she started with allergies issues, they took her off Zyrtec and put her on the singular. She had ALL the symptoms you read about. Cramping, muscle pain, had an asthma attack, ear problems, feeling of depression, EXTREME angry behavior, fly off the handle at the least little thing, feeling of not being "good enough", that she was a failure, had no friends, nightmares, scared. It was just unbelievable what we saw. For 3 weeks. Finally, when her period came about 2 weeks early, I thought of the singular, she had cramps, heavy cramps. Zyrtec had caused heavy bleeding and cramps and the doctor said that "could" be a side effect to the Zyrtec so let's put her on Singular.
I never thought to really read the insert when we picked up the medicine. I thought the doctor knew what they were doing. I have used this same group of doctors for 24 years. What a huge mistake I made.
She took the last dose 3 weeks ago,and within days we noticed how different she felt. More like herself. Even her teachers had noticed how she felt so down on herself.
Please share this.....tell everyone you know who has children with allergies or asthma. A drug that is suppose to stop, or prevent allergies is NOT suppose to cause allergy problems, or cause Asthma.

My son took singulair for over two years. He is now 9. Foe the last few years he has had a Jekyl & Hyde personality. Sweet as can be one minute then he will fly off the handle, calls us names, screams, breaks furniture. He also becomes emotional very easily. We have been baffled as out two other sons have never behaved in this way. I am now wondering if there is a connection with his behavior issues and his having taken Singulair for a long term.
