I can't believe what I'm reading tonight on this page, I decided ...

I've only been on singulair for 6 days and it is now 4:23am. I just couldn't sleep tonight. I've been having the strangest dreams and I commented to my wife about them. We just laughed it off. Anyway, at this time of the morning, my EARS are "Hissing" so loudly, not ringing, however I do detect a slight pulsating tonal sound in my left ear, that I just couldn't sleep anymore. I've a history of Tinnitus but something has exacerbated my tinnitus dramatically, so much so it is keeping me awake. I think I'll be needing something to help me sleep now. Perhaps I will stay off the Singulair for now just to see if life returns to some kind of normalcy. Could it be a side effect of Singulair. I don't know but I felt like driving something through my head to stop all the loud noise. Has anyone else experienced elevated levels, or a new development of "Ringing in the Ears", commonly known as Tinnitus?

I did a copy and paste of my reply to another poster. Here is my reply:
My son was "diagnosed" with Morbid OCD while on Singulair. In addition to this HORRIBLE disorder, he was aggressive, depressed, moody, sad, developed facial tics, nightmares, headaches, hallucinations (audio AND visual), ETC., ETC., ETC., and the list goes on and on and on.
ITS THE SINGULAIR! Unfortunately I didn't realize this was what it was and I let my sweet, wonderful little boy suffer for years. When I found the information that Singulair causes such horrible side effects I took my son off of it immediately. It took a number of months for my son to get back to normal (though I must admit, I had forgotten what that was after such a long time of dealing with his "severe thought disorder"). Today, he is happy, healthy and is now a normal thriving 9yr. old boy. SINGULAIR IS POISON! Take care!
