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  fluid on ears, difficulty breathing My son changed completely in the course of one week of this medicine. He has been hyper, unfocused, and full of fear and anxiety (nightmares, other fears). He has had intense stomach pain as well. He has dissolved into tears in situations he would have normally handled with ease. He's off the medicine and will not go back on it again. M 8 9 days

 1  My daughter had asthma. Neuropsychiatric meltdown. OCD, ADHD, nightmares, seizures, hallucinations. The anxiety and ADHD was during the medication, the rest of the symptoms came as Post Acute Withdrawl Syndrome. We literally lost our daughter for a little over four months to the side effects. Horrifying. Medical professionals are either woefully unaware or willfully ignorant of how this medication affects the human brain. Unfortunately you have to be a freelance pharmacist to protect yourself these days. We still get vaccines and take Advil and whatnot, but my GOD this drug destroys lives. I've seen it in hundreds of other cases firsthand. F 8 5 years

 1  Allergic Asthma My 7/8 year old daughter took this and experienced severe night terrors, anxiety, fear of death, INSANE aggressive behavior, kicking, hitting, etc., After discontinuing the medication she returned back to her normal, kind self although she still has some residual fear/night terrors. It isn't as effective for asthma as some physicians claim. Our pulmonologist suggested that a daily inhaler with occasional albuterol and maybe a daily anti-histamine is more effective at controlling the asthma. An allergist suggested the Singulair - the pulmonologist basically said it wasn't even needed. And he was right. She's gotten better in her behavior and asthma since stopping it. F 8 1 years

 1  asthma/allergies My son had been complaining of night mares, very scared at night when left alone in the bedroom to the extent I or my husband will put him to sleep every night, very disturbed sleep,very sensitive,cries for every little thing, lately expressed that he will die first than us his parents,very restless when sitting on a chair he will keep moving his legs or arms and said cant help himself and lots of stomach aches. It just donned on me now when I put everything together what Ive seen in my son and reading all the comments. It just scare me to death that I'm putting my son in this situation. Definitely, I will be stopping this medicine not to let my son take it. I will let his allergist know tomorrow. It is so sad that nothing has been mentioned in the leaflet with regards to this drug side effects. M 8 4 years

 4  Allergies/ asthma My 7 year old son was able to breathe and not have to use his inhaler as much which was wonderful, but his behavior suffered. He had mood swings, very irritable and aggressive. After going to this website and on-line I am going to discontinue singular and try another drug to help him. It there were no side effects with behavior he would still be taking it because it is the best medicine that we have found so far to help with his allergies and asthma. M 7 45 days

 3  mild asthma moodiness, easily frustrated, crying spells, upset stomache Thank you, I would have never connected the symptoms to singular. Although it has helped with the addition of Qvar to help control his asthma, I will now make an appointment with his pediatrition to stop singular and look into something else. He has been very emotional and has even started crying at school. He is having difficulty with school work and has always been in higher learning classes. I thought his moods were just a phase! I hope he does well without it, it does worry me to take him off the maintanence. He has been on it for almost two years.Has any one had any experiences with another allergy medicine? M 7 2 years

 3  Asthma Didn't think any until recently. I think it is causing my daughter to have anxiety. My daughter has been on it for close to 2 years, last year she started pulling out her hair and eyelashes, that stopped and now she cries and has loose bowels in the morning - exactly like an anxiety attack. She stopped using it last night. I hope to see a difference soon. F 7 2 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.

 2  exercise induced asthma anxiety, panic attacks, nightmares My 7 year old was prescribed Singulair during soccer season in fall. His environmental allergies and running cause asthmatic symptoms. After just a few days, he was like normal. He could run and be outdoors with all of his normal triggers with no reaction. This medicine does work, no doubt. But after about 3 weeks on the medicine, he confided that he had been feeling wierd at least once a day and couldn't make it stop. Upon further questioning, I realized he was experiencing panic attacks. He described that he felt like things were happening that weren't really happening, so I believe he was also hallucinating, or this could have been part of the panic attack symptoms. Lastly, he mentioned that he had some horrible nightmares about monsters recently. Knowing there are some serious psychological side-effects, we stopped the medication and anxiety and nightmares never occured again. If you do put your child on this, I would suggest asking them daily if they are feeling ok, as they may not realize things they are experiencing are abnormal or they may be embarrased to talk about it.

 2  my 7 yr. old daughter she is a high energy child who started experiencing very bad asthma and allergies at around 1 1/2 yrs. she was taking prednisone once a month for about 6 mos. and the dr. suggested singulair along with as needed albuterol and pulmecort inhalers. heavy medicine for a small toddler. she has been an intense child with mood swings, temper tantrums and extremely challenging for me. we tried herbs, which help, naturopath medicine and currently do vitamins as well. all of these things have helped, however i wonder, now that i am reading this, if singulair has created some of these symptoms. she often whistles and makes sounds obsessively. much of this is normal, but she is a bit more intense than most of our friends children when it comes to being stubborn and difficult. she has trouble focusing and listening to my words, like i have to repeat EVERYTHING 10 times, and my other daughter is not at all like that. i know this may sound totally normal, however, i spend alot of time with my F 7

 2  control asthma lack of focus in school, frequent urination, nightmares, emotional outbursts My daughter is 7 years old and was on this medication for 4 years for quite severe asthma. Along with steroid puffers she took singulair. The medicine did help control her asthma, but the side effects were consistent as well. Stumbling across this website, I asked her Pediatrician about the side effects (he stated none were proven). Against the doctors’ instruction, we decided to take her off Singulair. We changed our environment as well (taking all carpet from our home and replacing with hardwood throughout and adding a hepa filtration system). With these changes my daughters asthma remains to be controlled (next step is to take her off the steroid inhaler and have her med. free). The best part is; her mood has become much better, her grades in school increased from a "C" average to an "A" average. She now loves to read, she is more of a peaceful child and she is happier. Sure it cost us to upgrade/improve our environment (in which we needed a loan) but it was worth the money spent to see these improvements with our daughter. Our loan is now paid off and our daughter is a much better person for it - without Singulair. F 7 3 years

 1  Allergies Seperation anxiety, uncontrolled crying, general anxiety My 7 year old has been taking drug on and off since she has been 2. She has suffered on and off from bouts of crying, unexplained fears and SEVERE seperation anxiety that started out of nowhere. We were never able to pinpoint a reason until reading experiences of others. I mentioned this to her doctor when it all began and the idea of this med causing anxiety was dismissed. I feel so guilty for not checking into this sooner, and especially for not persuing it further. She asks way too many questions about death, dying and cemetaries and we could never figure out why. She cries when happy, sad, scared for just about anything at all. Always intermittently, never consistently. When you ask her why, all she can say is I can't help it. We could never figure what the trigger would be, now I have finally have a place to start. She is off the med for 10 days now, and hopefully it will work it's way out of her system sooner rather than later. F 7 4.5 years
