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 Behavioral Changes, Altered Mood, Turning into a maniac, Minor Depression that resolved after stopping. You should not take this medicine. I can't believe they even give this to kids. I took this for two years to control my Asthma, and it made me insane for those years. It altered my brain function and made me feel mildly depressed and hopeless, Made me lose my judgement and I could not make sensible decisions at all, It also made me do things that I regret now. If you are considering, or your doctor is considering prescribing this drug for asthma, there are better options available that won't make you insane. M 25 2 years

 1  Asthma A few weeks after starting my 5 year old on Singulair, he began having nightmares. And, later he began having night terrors! Every single night. As soon as we figured out that Singulair might be causing the night terrors, we stopped giving it to him... and, sure enough, the night terrors stopped! Thank god! :) F 5 7 weeks

 4  asthma Works great for the asthma and allergies..really has kicked any symptoms out of me, and I have had asthma my whole life....love not being on steroids like symbicort etc....although as strange as it sounds, the chewables (had to take them as my doc only had 5mg samples one time I ran out and had to wait for my refill) give me vivid dreams that are just messed up....and insomnia....thought I was just being crazy till I stumble upon this website...holy cow...didn't think this drug was the real reason.....although, i suppose given the alternative of steroids...this isn't so bad...just wish it wasn't some damned expensive..

 1  Seasonal Allergies My 2 1/2 year old son was prescribed Singulair for allergies (also takes Zyrtec and Nasonex). He had trouble sleeping, woke up with nightmares a few times, would wake up tired from not sleeping well, he would throw huge tantrums (throwing things, kicking and hitting the wall, screaming), and the last straw was the day he threatened me for trying to wash his hands. In his words, "I want to cut your face mommy." Needless to say, we took him off of it right away and called the doctor. Be extremely careful when you have a child on this drug. If there are ANY changes in behavior talk to your doctor immediately. M 2.5 3 weeks

 1  Asthma At age 5 my daughter has really been struggling with Allergy/Asthma. I finally gave in and started her on Singulair. After 1 week, I noticed SEVERE mood changes. Sad, Crying A LOT, issues with being away from me, not sleeping, sleep walking, and VERY aggressive. None of which is anything like her! Tonight is only the second night not taking it, and I hope this nightmare ends soon! I can't believe something like this is prescribed, and not carefully monitored. Zyrtec is our best friend!!!

 1  Asthma My young daughter tried it, but it made her mood swings horrible and made her just crazy. Since then, we took her off it and tell all doctors, she's allergic to her. Too many horrible side affects. Should be taken off market for children. F 6 5 days

 1  asthma, allergies I am amazed at finding so many others who have had the same experiences. Weight gain, (I did a couch to 5k last summer.Ran all summer and didn't lose ANY weight.) Depression,RAGE, & despondancy,(I took myself to a therapist because I was so estranged from my normal self.) Night terrors (approx 2-3 times a month I would hallucinate/dream and awaken screaming or with my heart POUNDING so it felt it might burst.) Night sweats, moodswings. Thought it was my age, but the past month w/ no meds has been WONDERFUL! I feel so much better! Just taking my inhaler every day. Starting to smile again. F 40 2 years

 1  Allergies Severe mood changes in school. Being a great student to being sent to the office frequently for his bad behavior. My 6 year old son took singulair and advair together for two months from October to December 9; because of his seasonal allergies he got sick almost once a month so his doctor recommended both medications. On November 7 the nurse called me from school that my son had peed on his pants. My son had never done this in school, but he said that he didn't make it. So I disregarded the incident. Then I got more calls from the nurse for the same reason and when I'll go to school to drop his clothes he will be crying that he missed me a lot. He got very emotional in school, all of a sudden he will start crying for no reason or scream in the middle of class. I didn't know what was going on. I had several conferences with his teacher were she said that he stop doing his work in class. I couldn't understand what was going on. I took him to his doctor and she said that he seem fine that maybe he was just going thru one of those periods were kids just get tired of school and work. We went thru this for about a month I got very frustrated. On December 9, I took him to school and came home crying and praying to God to help me find an answer. I went to the kitchen and saw his medication google it and found this website and many more forums describing the same symptoms my son was going thru. That day I took him off the medicine and call his doctor. It took 5 weeks to see a great change in my sons school grades. Thanks to God and these forums my son was back. M 6 2 months

 2  Allergies Crazy dreams, urinary urgency, nausea, depressed and very irritable This drug scared me into thinking I was pregnant! I had all the damn symptoms of pregnancy and I took a test and it was negative. Then I looked up the symptoms others have had from Singulair and I realized why I had been feeling so strange. It helped my asthma but it's not worth feeling like I'm going out of my mind. I'll stick with Zyrtec and Benadryl at night. F 23 7 days

 5  Asthma Nothing but good things. This has been a life changing drug on my part. I almost never have attacks, I can exercise and have lost 5 pounds already because i am able to exercise. I have a raised libido and have miraculously been in the greatest of moods. My only worry is long term affects. I wonder if i will truly be able to not worry about my asthma for as long as i am on this medication. M 25 45 days

 3  asthma flare up I developed a stomach ache, called the allergy doctor and he recommended I stop Singulair for a few days, then start up again to see if I got the stomach ache again. I stopped the drug, the stomach ache went away - and you know what? I'm not taking this stuff anymore. I am using an inhaler (Dulera) and I'm weaning myself off that too, hoping this asthma flare was just a temporary thing because I do not want to be taking any of this stuff in the long term............

 1  Asthma allergies My daughter was in singular when she was around 5 and I took her off because I didnt think it was helping .. Also her personality seemed depressed.. That being said recently we have had a hard time controlling her asthma exacerbations so her allergist suggested we try it again.... WRONG ! after taking it for 2 weeks I notice her personality changing ... Very angry, mood swings , yelling and screaming over little or nothing . This is not her Normal self .one night last week she came home from school and was very angry because we didn't have the snack she wanted. She started freaking out! I sent her to her room to calm down and she is screaming "Im gonna kill myself!! I hate you!! Then she opened up her window and jumped out!!!!!! She did not get hurt!! THANK God!! We live in a split level so it was not as high as a normal 2nd story window , but HIGH ENOUG!! Be very careful when taking this drug or giving it to children!! Weigh tbd risks and benefits !! Never EVER AGAIN!!! F 9 2 weeks

 2  Chronic Asthma and Allergies Horrible dreams, irritability, difficulty breathing, joint pain, sleepiness during the day, weight gain. When I first started taking Singulair I "thought" it was helping. I continued to take it even though my breathing slowly got worse. It got to the point where I was short of breath (SOB) all the time (something VERY unusual in the 60+ years I've had asthma.) Finally, the constant SOB had my Dr. send me for an Echocardiogram. Diagnosis was mild pulmonary hypertension. I continued to take all my meds until 2 weeks ago when I stopped the Singulair. My SOB has dramatically improved as has my joint pain and irritability.

Patient History
 4  asthma. allergies The headaches, nightmares, stomach aches, and anxiety all seem worth it to me right now because this has been the first time on my living memory that I can be anywhere near dogs. Not only can I go to my friends house, I can actually stay inside for more than five minutes! In fact, I was the last person to leave her party. Miracle. In this week I have petted more dogs than I have in 30 years. I'm even thinking about having my own dog. Only thing is, if these headaches, nightmares, or general states of anxiety get any worse, I will have to quit this medicine and be back at square one. Wish me luck! F 42 2 weeks

 2  allergic rhinitis (pollen, dander) My pediatrician had prescribed me singulair after many OTC antihistamines and prescription nose sprays (ex. Rhinocort, Flonase, AND Nasonex) had all been ineffective to my pollen and animal allergies. I had been making it through the 14 day trial period just fine until the last day where I broke out in hives. I was quite disappointed because until then, the singulair seemed to be working just swell. :( I didn't experience any of the mood changes, vivid nightmares, ect... Like others have been saying. I'll I would say is be careful what you are giving to yourself and your children. ~Nanners~ F 14 2 weeks

 1  Allergy/sinus I cannot sleep thru the night ..awake around 3:00 and finally get up frustrated by 4:00 to 4:30. I am so tired most hours of the day and so sad that I can cry easily, depressed as well This is not my normal personality so I know that this drug is probably the culprit. After reading the ratings on this site I will stop taking it as tomorrow. The small amountof improvement is not worth the side effects that I have. F 65

 1  for asthma and allergies I was prescribed singulair about two years ago to help control my asthma. After a few weeks, I noticed I was not feeling like myself. I was increasingly anxious and angry. I just felt down and negative about my life. I distinctly remember the day I figured out it was the singulair causing my mood issues. I was standing in my kitchen thinking about what to make for lunch when I became so angry I was physically shaking because I realized that my husband had eaten the last of the leftovers. I knew this was not a normal reaction, and I've never had anxiety or anger issues before or since. I stopped taking the medication and told my doctor, who shrugged it off and said there was no evidence that this drug caused my anxiety. I can't believe they prescribe this stuff to children :( Take it off the market!!!! F 30 3 months
