I am a 36 year old woman, and I have taken Singulair for the past 8 months. I got a lung infection over the winter, and the clinic I went to put me on the 10mg Singulair. It helped my lungs and got me over the worst of the infection, but I never anticipated the side-effects. For several months, I attributed what I was feeling to hormones (like severe PMS) and the stress in my life. I started to have thoughts of death, especially at night. I also began to have a hard time leaving my house. I would have panic attacks, worrying that the window was left open, the stove was left on, and god forbid there was a dark cloud in the sky (I became convinced that a terrible storm would come). Several times, I nearly got in a car accident racing to get home after work. Then, I started to obsess over getting sick. I was convinced that I would get some terrible disease and die soon. The fears and anxiety got worse and worse until one day (a rainy day), I quit my job of twelve years. It was a good job. I was happy with my work, and I made more than enough money. I ended up moving across the country back in with my estranged husband, because here I would not have to work. I could stay home all the time, away from germs and storms and anything else bad. That was three months ago. Still on the Singulair, I began to obsess over death. The panic attacks were so severe that they triggered asthma attacks, and not being able to breathe triggered more anxiety. I stopped sleeping at night. In three months, I've slept four nights. I began to have nightmares that made me wake up screaming and violently lashing out. I had to urinate 5 or 6 times every night. I developed severe stomach pain and nausea. And I had leg pain (actually, I hurt everywhere, severe pain). I had headaches, dizziness, and fatigue. Slowly, I began to realize that it might be the medicine. I started to research, and yesterday, I took my last pill. Since then, I have not had one panic attack. I have not had one asthma attack. I slept last night with no bad dreams. I know what's happened now, and I'm so sad that I lost so much of my life because of this drug. I really had a good life...friends, a home, a great job... Now, I'm very tired. My body is very weak and still hurting. I'm shaky. But I believe in time, those effects, too, will go away. I feel like my body has been through a war. I'm grateful that I didn't kill myself. There were a couple of really bad days when the urge to be violent towards myself was overwhelming. One day, I punched a fence, making my knuckles bleed. I think I could've killed myself, and I know it was Singulair. It's going to be better now. Just as a note: what helped me withdraw without any major worsening of asthma was Advair 250/50 twice a day.
