Went to my Dr for a sinus infection. I Came out with some Singulair and nose spray. Before the visit it was just a major case of Sinusitis. After the visit I thought I was going crazy. I have never experienced anxiety before. I am worried all the time, I thought I might be going crazy. I NEVER cry. I've cried about 4 or 5 different times. I feel like my arms and legs are restless, yet weak. I feel like I'm falling apart. I was in a constant state of worry, panic, anxiety and panic. I couldn't function, and when I could it was only barely. I ended up going to the emergency room for the Sinusitis because the pressure was so intense. I was given more meds and told to stay on the Singulair. I realized upon taking it the next morning that I didn't know anything about this medicine because I was given samples with no insert info. I looked on line...I found this site. Thank you for posting your side effects. I'm not going crazy. I'm getting off Singulair. By the way did anyone else have these side effects?
