I've been on and off singulair for several years. I had a horrible bout of bronchitis that then triggered bronchial reactive disease and I now have allergic reactions to certain chemicals (some spray deodorants, etc.) Singulair worked so much better for me than advair, I was thrilled to be able to talk and breathe. As a teacher I would sometimes have to stop the lecture to get my breath again and drink some water if I inhaled the slightest amount of chalk dust or something.
After reading the comments on this website I am going to discontinue taking singulair. I used to be this skinny person and never, ever worried about my weight. At the age of 37 I had a rip-snortin' major depressive episode with insomnia that had me miss 3 days of sleep (this is on no medication of any kind) and panic attacks and suicidal thoughts and impulses that I'd never had before. Imipramine was my first prescribed med (in 1991) and worked like magic. It cheered me up, calmed me down and made me sleep. I went from 135 pounds to 155 pounds in just several months. I finally got switched to effexor and trazodone, but there's really not been much weight loss. I'd hover around 150-160, but then with singulair added in the last several years I am 170 lbs. I can't believe I am a fat person now and do not over eat. I can't go off my psychiatric medication because it runs in our family and if I taper off I am...uh...crazy. My insomnia is tenacious when I am without medication and then that makes depression and anxiety worse. I never want to have a panic attack again.
I just ran out of my singulair prescription about a week or two ago. I am breathing and speaking fairly normally and my husband and I now have to pay for our own health insurance which is exorbitant and I just didn't feel like renewing the prescription in order to save money. I was pondering my weight gain today and just decided to google singulair and weight gain and I just can't believe it.
I have also experienced hair loss, but my hair is so thick it still looks basically the same. My husband and I have noticed over the last several years that I lose lots of hair after I wash it and there is a mass of hair in the shower stall.
My memory may have been adversely affected by taking singulair. I thought it's just getting older. I am 55. It's been the last several years that I have started to have problems remembering things. I have always had to work with my husband in helping him remember things (it's been life long with him: he is an absent minded professor. He has a genius IQ, is an M.I.T. grad, is an excellent engineer and can't remember his mother's birthday, what plans we have for the week-end, no matter how major, etc. to save his life.) I feel like I am becoming more like my husband in being hopeless and helpless about remembering what's happening from one day to the next. It could very possibly be the singulair. There has been a marked difference in my memory over the last several years. It is embarrassing. I sub for the school district and once showed up on the wrong day at a school and another time didn't show up and they had to call me up and get me out of bed to go to work. I also teach piano and never used to forget who was coming when. Again, I don't know if I can blame this on singulair causing memory loss, but there would be times when someone would knock on the door and I'd be surprised to find a piano student standing there. I feel like I am getting Alzheimer's. My grandmother had it for 17 years. My mom has always been afraid of getting it but she is 80 and is just now starting to show signs of real forgetfulness. I explained to her what my lapses in memory are like and she is shocked to hear that they are similar to hers. My mind just will completely go blank. I will have this thought, get distracted, and just a moment later will struggle to remember the previous thought and there is just a void, peace, blankness, white screen in my mind. Maybe it is getting older, but maybe it's the singulair. Since I'm just recently off it I'm going to pay attention and see if my memory improves or if it is just old age.
Also, my joint problems have been nearly ruining my life the last several years. I don't know if this is exacerbated by my singulair use or not. Bursitis in the hips runs in my family like crazy. We re-sided and painted our house several years ago and my bursitis started to flare up and has been bad since then, but it's also about the time I started taking singulair. I had to quit a sales job this summer because my bursitis has become so bad. Sometimes I can hardly walk. It is nearly unbearable. I get cortisone injections every 6 months, but need it every 2 months. I wonder if my discontinuation of singulair will ease my joint pain? I'm going to track that as well.
For me: weight gain, hair loss, joint pain, some dizziness are possible side effects from singulair.
Thank you to everyone who has contributed to this site. I am never taking singulair again.
