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 anger,nightmares,uncontollable crying, itching, pains in parts of his body, eye rolling, depressed and anxiety. My 7 year old son was put on this for allergies to help his asthma and it did that. But we started noticing behavior changes and he became a totally different child. It finally clicked when he woke up and his eyes were rolling constantly all day. I went on Singulairs website and noticed he had every side effect they had listed. We quit giving him the Singulair immediately. It's been 7 days today and he is slowly improving. His eye rolling is only once in a while or when he gets tired. Today was also the first time he didn't have a nightmare. I feel awful for not checking Singulair out before putting him on it. Thank you to everyone who has put something on here. It has been so helpful to read about all your experiences. M 7 6 weeks

 2  Allergies, possible asthma Wow! I am so glad to have found this site! I came on here to see if there were any negative effects to stopping singular, as they warn you on the label. My son started this at 3 and we've had a miserable year and a half! He became aggressive toward others, unable to control himself, and a complete nightmare. At his 4 year check up they recommended seeing an OT for sensory processing disorder. We have eliminated all processed foods, sugary drinks etc....well, I have not refilled his prescription in the last month and he has been an absolute angel. Honestly, he is a new child and we are all solo happy! I can't believe it has taken me so long to figure this out. M 4 1.5 years

 3  asthma sleepwalking, night terrors, bedwetting and in the last 6months leg pain, stomach aches. My daughter started taking this when she was 3 and is now 7. She was recently diagnosed with auditory processing disorder, dyslexia and ADHD. My husband found this website and we are going to take her off singular and see if it makes a change. Her sleepwalking is so bad we have an alarm on the house as she has tried to get out a couple times. Very scary! I will update post and let you know how things are going. Thank you all for posting.

 3  asthma/ allergies Noticed leg cramps first, then vivid and often scary dreams. Then angry, aggressive, defiant behaviours with increased social anxiety, difficulty getting to work (or anywhere) on time. I'm more easily frustrated. Tingling in extremeties. Lack of motivation. I've been on Singulair for about a month, although I do not take it every night (I forget). At first I loved it b/c it made me sleepy; I have bouts of insomnia but cant take Ambien, etc. because those side effects are worse than Singulair. I'm not sure if I'm going to stay on it. It does really, really help my allergies, the best relief I've ever experienced. F 41 60 days

 1  Allergies/Asthma Nervousness, inability to concentrate, emotional outbursts, mood swings, anger, depression, lower back ache, headache, waking up a few times a night, shooting pains in my feet, problems getting to sleep because my mind is racing. I had a bad bout with asthma that led to pneumonia and was prescribed this to get things under control. It worked well to control the breathing problems but the side effects are not worth it! I saw the warning about depression on the pill bottle but didn't think much of it at first. Be careful taking this drug! F 32 40 days

 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  Reactive Airway Disease Huge facial tics, anxiety, mood swings, uncontrollable crying My 7 year old daughter has taken Singulair regularly for 6 months, but her behavior over the past 2 days has been so bizarre I was compelled to do a Google search and came across this website. Last night was a complete meltdown over every single thing that could have possibly been a minor annoyance, such as not being able to squeeze enough toothpaste out of the tube, which culminated in a 30-minute screaming and crying bonanza. She said to me last night that she is "just not happy" and that she doesn't know why. I was reading stories to her tonight, and she must have popped her jaw open at least 40 times over the course of two books (mouth open wide like a yawn in fast-forward). I was keeping an eye on her, and a few times I asked her why she kept doing that and she said she didn't know, and she thought maybe her mouth was "itchy" - I said "baby, that's just not normal behavior" and she said "I KNOW!!! But I can't stop, mommy!" The moodiness and crying have become progressively worse over the past few months, but the facial tic for the past month is the final straw for me and confirms my suspicions about the other behavior - I stopped giving Singulair to her today. UPDATE 12/06/2010: The facial tic that my daughter had for about one month disappeared three days after discontinuation of Singulair, and her anxiety and other mood disorders slowly faded away shortly thereafter. Her chronic cough has reappeared, but I am managing those fairly successfully with Vitamin D and Omega-3 capsules F 7 6 months

 1  Allergy-related asthma Depression, anxiety, joint pain, most recently heart palpitations I have been on Singulair since it was approved for asthma in 2008. While it did help asthma symptoms, I have dealt with depression and anxiety for the past 12 years. It wasn't until about a month ago, when I started getting scary heart palpitations that I found online that Singulair can cause that. I discontinued the drug and have now realized that it was contributing significantly to anxiety and depression! This is the first time in over a decade that do not feel some level of anxiety or depression. I can "shake it off" when I start to feel a tendency toward those states of mind and I've not been able to do that in a very long time! Such a relief! F 40 12 years

 1  cough-variant asthma My son (almost 6) was on Singulair from the time he was 2 until a year ago when I took him off due to his EXTREME behavior. He was rude and defiant at home, but at first we chocked it up to the "terrible twos". Once he began attending daycare(2 years old), though, his behavior got WORSE. He would hit and push the other children, outright defy the staff, and would NOT follow directions/rules, no matter WHAT the consequences were(time out, mom called, etc). Last year he started attending Pre-K and the behavior continued, but the staff was NOT going to take it(they didn't have to, private school). he would NOT sit still, would not finish work, and the violent behavior continued. Since it really wasn't helping his asthma, since it isn't allergy-related, we chose to take him off it and see what happened. Well, it took a couple of weeks, but he's now like a DIFFERENT child! My son now(1 year later), is exceeding most, if not all expectations at school(kindergarten), well behaved at home, and actually will sit and read books with an adult and not be racing around the room. Even his pre-K teacher, who we went back to visit, could NOT believe he's the same child! I am SO glad we took him off it, we will NEVER go back. I was interviewed by a Fox tv station in DC for this topic and can't wait to see what(if anything) comes from it. M 5.5 2 years

 2  no Irrational anger, agression, hitting, crying, kicking, nasty, screaming, waking in night and they would tell me they didn't know why know why they were feeling this way. I thought I was a bad mom till I started researching this drug. Ther is a Natural Alternative called RESPITROL. Initially like most natural remedies it takes time to work but it does work AND there are no more irrational behavioral outburst. My kids were telling me they were bad kids when on that horrible drug. Now they tell me they feel really good like they never did before. Can you imagine how many parents think they are bad parents and other kids feel they are horrible kids? Spread the word and ask your doctors to help you use this product. If they won't, find one who will. We have to stop drugging our kids. There are so many great alternatives out there. Most drugs cause negative side effects, and aren't even tested for kids! They are unnecessary as I am also finding out... for example, most kids are deficient in Vitamin D which will prevent flu and colds. Diet is also important. BEAWARE: aspartame is in singulair which itself has many negative side effects like depression, irritability, anxiety and personality changes [it in a lot of your processed foods]. Educate yourselves! M 6 2 years

 3  preasthmatic syptoms Our daughter began taking Singulair at the age of 3.For two years, we had problems with agression, biting herself, refusal to listen, no remorse for hurting others. It was a nightmare. The meetings with teachers and their attitudes were not helpful. We left 2 preschool settings. Potty teaching also was a problem, and we are still completeing training. I was relieved to find this site. We took her off Singulair. We saw immediate improvement in her behavior, mood, cooperativeness, etc. I am sickened that it took us so long to see the negative effects of this drug. While it was helpful, and it helps a number of kids, I would initiate taking Singulair with great caution starting on a weekend and watching carefully for any changes in behavior, mood, etc. Our 5 year old is better now, but has lots of catching up to do because she was so unfocused during so much social training. She is now on allegra and seeing an allergist for her symptoms. I regret the precious time that she was so unhappy F 5 2 years

 1  allergies Emotional problems - anger, crying, etc. Have been through all of this for a year, including using zyrtec initially, then trying different prescription meds which all caused severe mood swings and extreme stress in general on our family. The best thing I've found is QBC (Quercetin, Bromelain, and Viramin C Complex) at our local herbal shop. Stops the coughing and has no side effects. We also use natural cough suppressents like Sinupret syrup, which is all natural, including the cherry flavoring. Also, using the Neti pot seems to help as well along with putting vicks on the soles of his feet and wearing socks over them when he sleeps at night. M 11 15 days

 2  Severe Seasonal Allergies Anger, Aggression, Hostility, Moodiness, Spaced out, Decreased Appetite, Irregular Sleep. I also noticed his face has blanched, eyes have dark circles, and he has been chewing on his hands constantly. (something he never does) My son started taking this medication only a few days ago due to severe uncontrolled allergies. Since beginning this medicine, my son has had severe mood problems that I was attributing to a cold he caught a few days before the Singulair was prescribed. In only 5 short days I my child changed from a sweet and usually happy go lucky little boy to an aggressive and emotional mess. He stopped napping, sleeping like normal, and he has lost his appetite altogether. He yells at me, screams NO to everything I say, and he has been chewing his hands constantly for the past 3 days. The temper tantrums haven't stopped since starting Singulair. I know he has only been on the medicine for 5 days, but the fact that I noticed such a big change in his behavior to google search "singulair behavioral problems" should tell you something. Effective immediately I am taking my child off this medication. While it has been the only thing to help his allergies, it just isn't worth the side effects. M 3 5 days

 3  nasal allergies It helped my allergies but I developed a sudden severe right elbow/arm pain. It was so bad, I planned on going to the emergency room but after using ice and ibuprofen, and not taking my Singulair, it was better. This is the second day without the drug and my elbow is at least 75% better. It is bearable so I will wait it out. F 60 7 days
