SINGULAIR  (MONTELUKAST SODIUM):  Montelukast is used regularly to prevent the wheezing and shortness of breath caused by asthma and decrease the number of asthma attacks. Montelukast is also used before exercise to prevent breathing problems during exercise (bronchospasm). This medication can help decrease the number of times you need to use your rescue inhaler. This medication is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose). This medication does not work right away and should not be used to treat sudden asthma attacks or other breathing problems. This drug works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies. It helps make breathing easier by reducing swelling (inflammation) in the airways.   FDA Approval Date: 1998-02-20 (Sources: U.S. Centers for Medicare Services, FDA)

 1  asthma hallucinations, very disturbing dreams, suicidal thoughts, depression, extreme emotional upset My 13 yr old daughter was on singulair for 6 weeks. She began having mood swings and saying life was horrible and not worth it. She took advil and Tylenol PM and thank goodness she told me. We ended up in the ER where she had to drink charcoal twice, was poked and prodded non stop, had to have a catheter, and her heart rate and blood pressure were extremely low. Honestly thought I might lose her. The child was so dazed that when she vomited the charcoal she couldn't even lift her head out of it I had to do it for her. Leave the hospital wondering if she's crazy until she gets home and tells me everything else that had been happening. She had been sleeping with the light on in her room all night (always had slept in total darkness with the door shut.) She said she had been seeing a man in her room wandering around and that she also saw him following her at her school. She was having horrible nightmares that she was dying and couldn't stopit. Terrified that she would not wake u M 39 6 weeks

 1  Flair up of seasonal allergies Depression, moodiness, extra sensitive, weepy, anxiety, dry mouth, hard time focusing and was very tired. I only started taking the drug 12 days ago. It seemed to help with my allergic flairup (seemed like a sinus infection without the coughing). I did experience a very dry mouth at first, but this side effect lessoned and I started feeling anxious, had a hard time focusing, very tired and starting becoming very sensitive, moody and depressed - without any prompting - which made no sense to me. It was like someone was pressing a button inside my head and making me depressed. I do take Wellbutrin for depression, which has worked successfully for me to this point. I read the singulair insert for side-effects and only continued taking the drug because I thought the depressed feelings must be coming from something else - a busy life style? Nothing I haven't handled before. Then I went on line to see if anyone else experienced depression as a side effect and found this site. Thank you for sharing your experience. I will stop taking this drug and am sure the side effects will disappear. This is not the first time I've experienced side effects that weren't on the label. My doctor has told me that if you get a side effect when you start a drug and then you stop it and it stops - well I guess you need to do your own research since we're all individuals with our own chemistry. I could be prone to the depression side effect. I'm just so happy - I thought I was losing my mind! F 39 12 days

 1  seasonal allergies repeated ear infections, sinus infections (never had problems with any upper respiratory infections before), irritability, weight gain, headaches, sinuses felt like they were closing off if missed a dose It was great for awhile, the best drug I ever took for allergies..suffered with them all my life, it relieved all symptoms to the point of not even thinking about them. Then the side effects got too bad to continue using. Looking for a replacement! M 39 2 years

 1  Asthma & allergies I felt Singulair worked very well for my asthma and allergies, however I had 3 seperate increasingly violent nighttime episodes where I believed someone had entered my room while I slept and I attacked them. It turns out I was only attacking my lamp, and a wall. The 3rd time I hurt myself so bad that I am still unable to walk on my swollen knee. I recommend making sure you aren't prone to sleep walking or nightmares before taking this medication. I have stopped taking singulair after realizing these instances began after I started taking this med 6 months ago. I recall terrible dreams as well. I was a sleepwalker/talker as a child and have always had some issues around sleep but these episodes were extremely out of the ordinary and obviously well out of my childhood F 39 6 months

 5  Asthma/allergies Vivid dreams A godsend for me! My breathing is SO much better; I didn't realize how bad it was until I started taking Singulair and felt the immediate difference. Have only had to use rescue inhaler three times since starting it. It doesn't eliminate my nasal allergies or itchy eyes completely (I take Zyrtec, as well, which does help), but I no longer have the constant low-grade sinus infection (no more yellow, um, boogers; no boogers at all, in fact), don't get sinus headaches anymore, and have noticed (oddly) that mosquito bites don't swell up like they used to. Wish I'd taken doctor's advice earlier to try Singulair. F 40 3 months

 5  Severe Asthma & Angioedema Within the 1st week, crazy vivid dreams. Then, after 3 months of consistently taking meds: insomnia (restlessness in bed, jumpy legs), severe irratibility (snapping at people over minor issues, total loss of patience), and scary agression (almost reached out & slapped someone in anger - i have never hit anyone in my life & rarely raise my voice). This drug is a miracle for me, it was the only med to completely fix my severe recurring angioadema and athsma allowing me to return to work (in truth, to hold a job) and sleep at night without waking up b/c I couldn't breathe. I'm so saddened these side effects have started. I don't know what to do; no other medication has so effectively helped, but I can't imagine continuing with this severe change in my personality - it scares me and it's not fair to my family.

 4  asthma-wheezing GREAT: as a sleep aid (for falling asleep) and for my wheezing (excellent) BAD: trouble concentrating or thinking clearly, mispelling words, dry mouth, blurred vision (not sure if Singulair is cause, yet because I'm also taking Claritin-D 24 and Thyroid), migraines w/ aura, sensitivity to light I stopped for one night and noticed a difference today. I can think clearer. Last weekend, I did not take it for 3 days. Upon restarting, I felt terrible that morning and received a migraine. BUT....it is GREAT for my wheezing and for falling asleep at night. I am going to continue my log of observations. It is too early to give definitive comments because I also take Claritin-D 24 during the day and am hypothyroid. F 40 2 years

 3  rhinitis, asthma, bronchitus After 6 mon.of use: fatigue, itchy legs, itchy and tingling fingers, dry eye, incontinence, colds, flu, sore throat, side and leg cramps, weight gain, erratic digestion, anger spells, crying spells, insomnia, acid reflux Had Recurring Bronchitus that turned into Asthma. Had coughing episodes to coughing all the time and wheezing at night or after physical activity. Got a bacterial lung infection and was prescribed antibiotics, Singulair and Advair. Worked first few months for my breathing, heavy chest, and cough (with cough medicine at night). Stopped Advair due to mouth sores and very severe sore throat which I never had before. Decided to try to get off Singulair because my coughing, acid reflux, and heavy chest are coming back; like I built up an immunity to the drug. Also, even though it helped all my lung and itchy nose issues, I was sick every 3 to 6mos. like clockwork with severe cold and flu symptoms. Had to have Depo Medrol shots. Been off 4 days and have a sore throat and no fatigue or cramps. F 40 2 years

 3  Asthma CHRONIC HIVES, vaginal discomfort- itching, soreness, raw. Hallucinations- Hearing distinct noises that jolt me awake, sound of sliding door opening and someone coming into the house, someone calling my name, someone screaming a shout at me, seeing things, sometimes vivid dreams, tightness in eye cheek area tension face, different and strange type of headache, ITCHING FEET! I have infectious asthma, which means that I get asthma once I get sick, I also have hyper active respiratory disorder, both are so bad when full blown that I fear dying. Singulair helped me control my asthma, cutting the time it took me to get control over my airways from 3 months after an illness to about 4-6 weeks. I was so satisfied with the results I would take claritin to control the chronic hives, from head to toe all day long. However the vaginal dryness, inflammation, itching etc. is too much to bear. I will have to stop using this drug. However I would continue it if I did not have this side effect, tolerating most of the others including the chronic hives an d hallucinations. F 40 9 months

 3  Asthma Pediatric Taken by daughter (born nov 2001). She complains of itchy feet at night. She is difficult to get to sleep. It takes her 2 hours to fall asleep every night. With asthma it is hard to tell if something is effective. She still has difficulty when she catches a cold with wheezing and coughing. F 40 2 years

 3  allergic rhiniti/mild intermittnt a wt gain, craving food all the time increased need for sleep, difficulty starting tasks I would take this again for a short period of time during a fierce allergy week or a brochitis, because it works well, but I gained 10-15 pounds. I'm craving food all the time. I'm needing more sleep and having a terrible time waking up. I'm having trouble getting thins done and I am more irritable. F 40 2.5 months

 3  Exercised Induced Asthma Insomnia, loss of memory, lack of concentration, fatigue Funny thing, when something obviously works (I can now work out w/o having to puff on a rescue inhaler) but the consequences outweigh the benefits. It's EXTREMELY frustrating to be tired, yet not be able to sleep/stay asleep. Also, the inability to focus and loss of memory is downright frightening.. I thought I was losing my freaking mind until I found this site and found others experiencing the same thing while taking this drug. No more for me.. I'd rather puff the damn inhaler when I work out. At least I can remember my kids names when I leave the gym... M 40 1 months

 3  Allergies Dirrhea, Watery stool, anxeity, stomach pains after I ate, upper and lower back pain and headaches Singulair worked for my allergies but the side effects were to much for me to handle. It might work is some people with no side effects but I cannot fathom taking a drug with the side effects that happened to me I mean to give you an example after I ate something I would experience stomach pains then not shortly after run to the bathroom. since coming off of the drug the side effects have gone away. I rather suffer than take this drug! M 40 25 days

 2  asthma - allergies extreme fatigue, weird muscle spasms, sick/nauseous/headachy feeling waking up from any sleep (no longer able to take naps), depression. at first I was pleased with singulair. my asthma, especially nighttime coughing was completely eliminated. however, after going off of it as an experiment over the past week, many strange and very uncomfortable physical symptoms that I've been having have gone away completely. Energy-wise, I've felt as if I've been run over by a truck and any sleep has been awful. And along with bad dreams and waking up feeling quite ill, the overall quality of my life has totally eroded. I had no idea it was Singulair! argh. F 40 6 months

 2  Allergic rhinitis/chronic sinusitis At first I was thrilled - finally a wonder drug for my allergies! After a few weeks, I started to get really itchy, especially on my hands, around sunset every evening. Large red splotches would appear on my chest and neck. When I would scratch, welts would raise. As I continued to take the medication, I developed increasingly severe welts in response to the slightest skin trauma. It got to the point that I would have huge welts that would leave scars along the waistband of any of my pants, and I couldn't let the edge of a sheet of paper touch me. I stopped taking Singulair, and worst of the symptoms were gone in a few days. It took about six months for the last of them to totally disappear. This stuff SCARES me! Very disappointing. F 40 3 months
