Worst night of my life--woke up feeling filled with anxiety, insomnia, had to get up repeatedly to urinate, felt very agitated, though I felt very peaceful & relaxed at bedtime, feet were swollen so badly I couldn't put on my shoes. I took 10 mg of Benadryl, which did not change how I felt. My internist took me off the Singulair immediately, when I contacted him the next morning. Despite being on an antidepressant which was recently increased, very recently I felt sad, anxious, and was crying all the time, felt irritable, and was chronically tired. I took 400mg of gabapentin (Neurontin), prescribed for nerve pain, numbness, tingling in both hands & feet at 9 p.m. Just before bedtime at 10:00 I'd take 10 mg Singulair. 1-2 hours later I was wide awake, sometimes not sleeping for hours or at all, even after taking 1-2 Benadryl, without the dyes. Over the past two years I've had eczema, for which I saw 2 different dermatologists and an infectious disease specialist. Eczema was so bad, I couldn't sleep at night. I consulted with every imaginable doctor, including the allergist who prescribed Singulair & was told it couldn't be the Singulair because Singluair was FOR ALLERGIES. Was diagnosed with fibromyalgia by a neurologist, recently had a repeat of an MRI because I couldn't walk the pain was so bad. My neurologist was unable to find any reason I had pain & difficulty walking, after reviewing the results of the MRI. I've seen my internist for heart palpitations. When I reported urinary frequency, he had me get a cystocopy (negative) because I had hematuria, blood in my urine, and I had weight loss. I still have many of the side effects, like the numbness & tingling in my feet and hands, however, I am able to sleep through the night and did so immediately after going off the Singulair. A lot of the fibromyalgia pain I was having has subsided, depression, anxiety has subsided as well.
