I heard about this on NPR on Friday morning and cannot believe what all I have read about to date. We have been to so many psychologists, psychiatrists, play therapists, neurology, allergy, and so forth trying to explain her behavior. We have had so many different theories thrown our way that it's hard to know what to believe anymore. Not one medical professional noted that her allergy meds could be partly to blame. After I listened to the initial report, I was talking to my small circle of friends about some of the problems we have been experiencing with our daughter for years. Everyone that I have spoken with that has children on Singulair all complain of similar problems in their children- they say they wish they weren't alive, show extreme rage , hate to be alone, etc. I am no medical professional, but I cannot afford to see if this isn't what is causing our daughter's behavior. Certainly after reading these postings I'm even more convinced about the connections. I would be remiss if I followed my pediatrician's advice and continued her on Singulair. Finally, I see some light at the end of this long tunnel and I no longer feel so isolated.
