For Allergic Rhinitis "I wish I had reported this to the FDA when it happened. I don't know how helpful my account of the side effects from many years ago would be now. However, I would like to share this somewhere, as what I experienced is not verified as a side effect but possibly suspected-I don't want anyone to go through what I went through and not suspect this medication to be the culprit. After taking one dose of Singulair in the evening, the next day, I experienced suicidal thoughts, severe anxiety, and a feeling as if I were being separated from my body (if that makes sense). I have no history of such problems, never took Singulair again, and never experienced what I described again."

For Allergic Rhinitis "My wife was on this stuff for at least a couple of years. She suffered severe tiredness, nightmares, irritability, and even suicidal thoughts, accompanied by severe depression! Although it did make her feel better, the side effects are not worth it at all! She switched to Flonase, and it is just as good. Please, if you are on this medicine and have any of these side effects, please stop!"

For Asthma "On this medication, I could finally sleep at night, literally. It helped so much with my asthma and my allergies. I could take deep breaths again. I needed my inhaler much less. But unfortunately, like many others, after three months of taking this (it takes time to build up in your system), I developed severe depression and I was very suicidal. Thankfully, I have a support system that I alerted of this possible side effect, and they were there for me. I went to my doctor, and she advised to stop taking it (as I uncontrollably cried in the office), and I felt better within a week of being off it. Don’t let my experience scare you, because I really went back to normal as soon as I got off it. I have yet to find a new medication that makes my asthma/allergy so nonexistent!"

For Allergic Rhinitis "I have tried Singulair three different times. Each time it has caused suicidal tendencies in me. This happens soon after I take it. My mood was very scary on this. I was prescribed this for asthma and allergies. I stopped taking it since it seemed to just depress me."

For Asthma, Maintenance "Singulair caused suicidality for me. But it was a very strange kind of suicidality because it was very cold and intense. I didn’t feel super distressed, or sad, or even depressed, I just felt very clear that I should plan for my death and make it happen. Luckily, I realized that was weird and connected to the medication. As soon as I stopped the medication, the suicidal ideation went away. This medication could’ve literally cost me my life, and it shouldn’t be on the market."

For Asthma "To the moms reading these reviews because your kid is taking this medicine but you can tell something isn’t right and wonder if it’s Singulair-listen to yourself. My son was on Singulair from the age of 5 until 19. While it did help his asthma, the side effects are not worth it. As a child, he could never sleep, had tremors, sweated like crazy, had anxiety and depression. Watch your child when they get to high school because something can change at that age and it seems the depression gets worse, suicidal thoughts began. My son stopped his meds on his own. Felt a lot better. Started having asthma issues, so he started it again at college for a couple of weeks. He is old enough now to be able to identify his feelings. He told me he stopped taking it and will never take it again because it made him suicidal."

For Allergic Rhinitis "If I could give no stars, I would. It caused me to have suicidal thoughts, and I put a fork to my throat this morning over something stupid, and my mom talked me out of it. I’m not the suicidal type, and Singulair made me want to take my life. I also have had aggression, worse depression, rage, and not giving a rat's booty on what I say to anyone. I talked to my mom like she was a nobody, and I’m not that kind of person. I even cussed my own husband out a couple of times. I would NEVER talk to anyone like that! I was literally scared of myself. I even broke something of my great-great-grandmother's, and it was one of the last objects my mom had of hers. I’m not the violent type at all. I’m hoping within a few days I can start feeling better."
