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 When I first started singuliar, my asthma improved for the first few weeks, then my asthma went back to the way it was, I would have an attack at least once a day. I thought, why take this medication when I am having the same amount of asthma as before the singulair. After a few months on it I decided to stop taking it, my asthma became severe, like I would have an attack every 3 hours and use my albuterol. I gave up, now have been on it for about 2 years. Tried slowly weaning myself off it, can't seem to. I just stopped cold turkey two days ago and my asthma is out of control. Also, doctors have had me on steroids my entire life, as I got older, I would get sick more often and more severe. Sinus infections, broncitis, pneumonia, many times a year. I stopped all the steroid inhalers and prednisone about 4 years ago, it took almost a year for my immune system to recover from the steroids, but once it did, it was great. I never have to go to the doctor for sickness, my body can fight the F 35 2 years

 1  Asthma and allergies Nightmares, severe anxiety, severe social anxiety, insomnia, severe depression, and agitation I’m a Registered Nurse. When I first started taking Singulair, I looked up the medication information in my nursing drug guide and in my nursing textbooks. Back then there were no warnings about any adverse effects such as depression or anxiety regarding Singulair. I figured it would be safe to take. This has been the worse year and a half of my life. Less than eight weeks after I started taking Singulair, I fell into a deep depression that lasted about four to five weeks. I have underlying issues with anxiety; the Singulair just multiplied my anxiety by a hundred. My anxiety has never been this bad. I started to have severe anxiety attacks and severe social anxiety at work. The anxiety worsened over time as my thoughts became more negative. I started having anxiety and panic attacks around loved ones. I started to see a therapist, but that didn’t help at all. I had to start seeing a psychiatrist; this helped only a little. The psychiatrist prescribed an antidepressant and a benzodiazepine. These medications helped slightly. I notified my primary care doctor and had labs drawn. Everything was normal physically. I was doing everything that is supposed to help with depression and anxiety. I was eating healthy, I was lifting weights and running 3 miles, positive thinking, cognitive behavioral therapy, and I was even meditating. Nothing was working for me. I have never felt so helpless. I have never been so anxious or so depressed before this. Fi M 35 1.5 years

 1  asthma What started off as a difficult 4 year old turned into depression, mood swings, extreme weepiness, suicidal thoughts as he got older. Thought my child had severe emotional issues and was looking into medicating those when I began to suspect the Singulair. Took him off the Singulair and all those went away. Hate that he had 3 horrible years of his life that I just thought "he would outgrow." Helped asthma a lot but side effects were severe. F 35 3 years

 1  Allergies Nose bleeds and gums bleeding. I stop taking the drug 10 days ago and I am still bleeding from the nose and the mouth. I have no history of any ailments that could cause this and I regularly visit the dentist and have good oral hygiene. I hope the bleeding stops soon as not I have to deal with 2 problems instead of just one. M 35 30 days

 1  To help control my asthma Fatigue, & mental effects such as irritability, increased anxiety, mood swings, loss of interest, & feelings of hopelessness I began taking this med at the end of June 2020 because I had been battling my asthma all year. At first I had no adverse reaction to the medication. The symptoms didn't present themselves right away in an obvious manner...they slowly came on. I became so irritable & had zero patience with my children. I had big mood swings, increased anxiety, i developed a loss of interest in things, felt fatigued all the time & I began to have feelings of hopelessness. It is not a constant thing, it would come & go to where I would feel crazy at times. About 2 weeks ago I began to notice these symptoms getting worse especially the hopelessness feeling, as if I were spiraling downward. After a huge meltdown, I asked God to help me & this medicine popped in my head. I decided to google the symptoms however I didn't want a generic list of symptoms, i wanted peoples experiences & i eventually found this site. As I read the posts on here about this med, I immediately recognized that it was this medicine that was doing this to me! I cannot believe something like this is on the market & for children even! It is an extremely dangerous drug in my experience because some list suicidal thoughts as one of their symptoms & even though it didn't get to that point for me, after experiencing the slow onset of my symptoms I can see how this drug could possibly slowly lead someone to suicide! Thats nuts! I dont know what might have happened to me had I continued to use this drug! F 35 3 months

 5  asthma None at all I switched from Advair (which made me angry, agressive, have nightmares, have crying fits) and found that Singulair was a dream come true. I have had no side effects, I sleep like a baby with no drowsiness the next day, and I can finally walk the stairs! I noticed where another person had sores in him mouth...I did as well, but it turned out to be a viral infection and not associated with the Singulair at all. F 36 6 months

 5  Asthma None This has been a 'miracle' drug for me. I spent my entire childhood and early adulthood struggling to breathe. Now, with Singulair, it's like I don't have asthma. I can do anything without any asthma problems. F 36 14 years

 5  Chronic sinus infection, None My 7 year old daughter has been on singulair for chronic sinus infections and post nasal drip for about a year. It has helped her greatly, and the symptoms return as soon as she stops the Singulair. I can't help thinking that many of these so called side effects that parents are seeing are merely behavior issues. As a teacher, I often hear parents blaming medication for their child's behavioral issues. These parents may want to look beyond the medicine to see if there are other reasons for their child's issues. F 36 1 years

 4  constant sinus infections Just started to do research into possible side-effects of Singulair. This is after 3 weeks of chronic fatigue, decreased sex drive and occasional rage issues. Aside from the side-effects of this medication it has been a wonder drug for me. This time last year i had bronchitis twice and pneumonia once (brought on by chronic sinusitis). I do now realize that my fatigue and decreased sex drive may be caused by Singulair and plan to reduce how often i take it. M 36 6 months

 4  Allergies Vivid dreams but nothing horrible. I guess it all depends on what skeletons are in your closet. Seems to work fine. my 6 year old daughter has taken it with no side effects. As with all new medication theres a bit of anxiety about taking it. I see alot of bizarre psychological issues on this board like aggression and even masturbation but those sound more like behavioraly issues. Ive never seen a drug force someone to do anything any. Can it make you irritable ? sure, some may but Ive seen no side effect from it yet. M 36 1 months

 4  Allergies (runny nose & sneezing) The first year I had none. However I recently clued in that the past 3 years of fighting itchy, dry skin is a side effect of this drug. I never thought it could be because I had no side effects the first year I was on it. It started my joints were itchy, then it developed into raised little bumps/hives, if you scratched it would leave little red dots on your skin for a day. My arms, waist and legs have dry scaley patches. It obviously got worst as time went on. My background is I have asthma and environmental allergies. The itchy red dried skin took over my life and it is worst then having a constant runny nose and sneezing my head off. I loved this drug because it gave me a life again just wish I hadn't been so sensitive to the side effects. I went to a few specialist to help and again no one clued in that it was the drug I was taking. F 36 4 years

 3  Allergies Was working well for the first 3 days until i found myself becoming withdrawn and sad for no apparent reason. Headaches, anxiety, weird dreams, rash on my chest and tingling in hands and feet developed around the 8th day . After 14 days during my follow-up with the ENT, he told me to stop as i was sensitive to the drug. I am ALOT BETTER NATURALLY !!! I would never use this or any drug that interferes with the brain again. Always read side effects of your meds and if u notice any that makes you uncomfortable, STOP ! For my allergies now, i treat myself naturally with ALoe Vera juice , netipot, olbas oi, vitamin c and avoidance to the allergens. Keep your surroundings clean and free of dust at all times and eat healthy. F 36 14 days

 3  Asthma, allergies (son and daughter Daughter - anxiety, severe stomach pain (esp. at night), mood swings, unreasonable fear, nightmares, crying and tearfulness Son - leg pain, irritability and anger, mood swings - he'd go from angry to crying in seconds, inability to focus, forgetfulness My children have been on this medication for over 2 years and I never associated their symptoms with this medicine until my husband found this website. I am horrified that I have kept my children on this as long as I have. It did control their asthma, but it is not worth the misery that the side effects have caused in our lives over the last couple of years. My daughter has been put through several tests to determine the cause of her stomach pain (all tests have come back normal). Why did her doctor not mention that this could all have been because of the Singulair, she knows that she is on it. My daughter stopped taking the medication last week (allergist's orders) and there is already a decrease in nighttime stomach pain and in nightmares. Since reading this site, I have decided to take my son off of the medication as well. I feel so horrible about all of the suffering my children have endured. My son's symptoms have not been as interfering as my daughter's, but I can't bel F 36 2 years

 3  Seasonal Allergies and IC VERY Vivid Dreams - mostly in the nightmare category While this med has truly helped my seasonal allergies and my IC symptoms - I am becoming quite concerned about the vivid dreams I am experiencing - I have been on this medication for approx. 2 months and all of a sudden the last 5 constant nights I have had horrible - nightmares - that are VERY vivid - Does anyone know if a delay in symptoms like this is possible F 36

 3  Severe asthma and allergies Irritability, anger, frustration, depressed mood. I have been taking this for 2 years and it really keeps my asthma under control but I have always been very level headed and patient and lately I have felt just sooooo quick to anger. I stopped taking and it is like a valve has released way less angry and more happy. It is hard though because it really helps my asthma so much. Allergy season is hard to get through without it.

 2  Asthma triggered by allergies mood changes, intense worry, spontaneous weeping, sleep walking, aggression, absent minded, vivid disturbing dreams, lack of concentration, dizziness Started zafirlukast (Accolate) in 2009 with Qvar, to control asthma. My asthma is much better controlled. Switched to Montelukast (Singulair) 1 month ago, was instructed it is the same class drug. When I started Accolate my life was in a major shift. I started having intense feelings of self doubt and worry, accompanied by vivid, strange dreams. I just figured it was stress. Years have gone by on the Accolate, the worry and dreams have persisted. The worry is accompanied by fits of weeping. I get dizzy, have trouble concentrating & feel like I'm not as sharp. Then there are the dreams......! They are INTENSE, horrible, colorful; motion picture-like. These experiences were previously just not normal. Roll forward to the last 6 months. I started having events of "sleep walking". Never had them before. My husband reports that I wake up, go to the bathroom, come back & start verbally abusing him. The events happen randomly. Been on Singulair for the last month. I take it in the morning to avoid the dreams. They aren't as bad, but they are still present. Last night I had another sleep walking spell. This time was the same as before (I'm told) but this time I struck my husband hard enough to split his lip! I do NOT hit. That is NOT who I am!! What's worse, I have ZERO recollection of the incident. He told me I hit him with my right hand, I'm LEFT HANDED. I can deal with the depression & dreams. I CANT deal with violence/abuse.
