Preemie symptoms and conditions

My daughter who just turned 6 has been on Singulair for about 3 years now. Her behavior has not always been the best, but with her past medical history ( a preemie) and all the things we have gone through some times its just easier to give in than to fight over it!!! So last week she was suffering with her allergies and asthma and the doctor added a Claritin to be taken once daily. I didn't really think to much about it and thought well if it is going to help her the OKay. That was on Wednesday and by the week end she was literally coming "unglued". She was lying on the floor when she should have been in her seat at the dinner table. When she was in her seat she was doing "back bends" over the chair. We finally come to the conclusion that it had to be the Claritin, I looked up the active ingredient loratadine and knew I had to get her off it immediately. So now I started to investigate the Singulair as well, which I should have done long ago. Today will be the last day she takes Singulair as well. She has complained of her stomach hurting for a long time and I always blamed it on constipation, but it could be the Singulair. I can only pray that she will not have any lasting side affects.

IS THIS SITE AN ANSWER TO OUR PRAYERS?

A little while ago less than two hours, after a very emotional, difficult battle with my daughter, we had yet another heart to heart to try to do better. At the end of our talk WE PRAYED for guidance to know how to help the situation. So I'm here looking for a link to her behavior fron the ADHD medication and I see someone had posted about Singulair side effects. I was floored! I have never thought that Singulair was not a safe drug. No doctor has ever mentioned any negative side effects to me regarding it. The more I'm reading about it the more in shock I am. Have I and her doctors been doing this to my daughter? My 12 1/2 yo daughter has been on Singulair for probably 10 years. She was a 28 week preemie and had severe lung issues so it was a needed medication. Her behavior has worsened the older she has gotten. Because of mostly anger issues and problems in school about a year ago she was started on ADHD medications. We are currently trying to find "the right one" . I feel so awful. Could all her misery have been caused by this little pill that was suppose to help her? Why has her pulmonoligist continued to give it to her although she has not had any serious asthma problems in years? I think I will stop all medications and see what happens. My daughter has also been on amytriptylin for about six months also for severe migraines. What do you think? Should I stop all of them cold turkey or gradually decrease one at a time? I would GREATLY appreciate any advise.
Thank you
