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)

 3  Asthma & Nasal Allergies My 13 yr old son has been taking Singulair (10 mg) for several years. I am looking for the reason that he is beginning to fail in school. Not finish assignments, not turn work in, etc. Is this the medicine or just adolesence. The medicine has seemed to keep in asthma & allergy symptoms in check, although he also takes singulair. After reading the information on this site, I am going to use parental perogative and take him off of it to see if there is any improvement. We will see what happens. M 13 3 years

 1  for asthma and allergy My son became more sensitive and very serious.Shortly after falling asleep my son would wake up with night terrors. He was really asleep but could not wake up.He was very scared and acting crazy.This had not happened since he last took the med 3 years ago. I forgot this med was the cause and now took it for 2 days and the results were the same as 3 years ago After comforting back into bed and telling Him he was OK he eventually fell asleep.3 years ago he was taking for1-2 years and he had many night terrors. After it was out of his system he never had them again. Even if it took all asthma symptoms away it is not worth taking if a person's mind is so affected. M 13 2 days

 1  Allergies mood changes, bad nightmares & vivid dreams, thoughts of hurting others to the point of wishing they were dead, anxieties & panic attacks, stomach ulcers, developed hyietal hernia, loss of concentration, lost 30 lbs within less than 6 weeks, choking sensation when swallowing, loss of appetite, depression, he felt like a balloon bursting in his head with 3 weeks of taking singulair. Started taking med Nov 13, 2008. Three weeks later teachers at school recognized a change in behavior that was not typical or noticed prior to the med. The end of Dec. 2008 loss of appetite and increased mood changes and noticeable aggression toward others and unable to change feeling even knowing his thoughts & feelings were not typical or right. Jan 13, 2009 realized it was the med and he stopped taking singulair. Not only is my son still trying to recover from physical effects, he currently is trying to recover emotionally. No longer able to attend school and in a homebound education program. Would not recommend this drug to anyone. Was taken to the emergency room 3 times within the last month and a half. Was admitted to the hospital twice and a phsyciatric treatment facility once and currently going to a phsycologist weekly all within the last month and a half. M 13 1.5 months

 1  Athsma/allergies I was in the 4thand 5th grade when I took Singular, and at first it seemed to work great and really helped my health. Later on, though, I started having suicidal thoughts and depression, and I was really worried about myself. I would cry a lot and refuse to go to school, and I had a lot of trouble focusing. The side effect of depression and suicidal thoughts with Singular was not yet announced, and my parents couldn't figure out why I was acting this way. Dismissing it as the recent death of a family dog, I went off Singular about 4 months later because I was switching to a day and night ashtma preventative called Advair. The changes in my behavior were apparant, however, we just thought I was finally accepting the death of a pet and moving on. A couple of years later it came on the news about how Singular caused suicidal thoughts and there were already 4 people who were on Singular that had commit suicide because of it. It works, but it's NOT worth the side affects. Now that we all know it can cause behavior problems, depression, suicidal thoughts, and aggression, there are plenty of other medications that will work without the disturbing side affects.

 1  Montelukast generic brand for allergies My son has been taking this drug since he was 4 years old . He stopped taking it by 11 years old. This drug gave him nitemares , depresssion ,suicidal thoughts ,headaches, and anxiety. He doesnt want to be around people or go outside. My son likes to stay inside play his videogames and text in the phone with family. He is getting better at socializing especially with family now. He has anger issues too. I wish the nitemares would end for him. This drug has caused my son nitemares since he was 4 years old but I really didnt pay attention to it. He stated he had them at early age. Please review this drug .. Its not a great med for children. Parents be cautious with this med. M 13 7 years

 1  Asthma Vivid nightmares, Very Fatigued , Mood swings, Foginess, Loss of concentration especially at school, , Redness & puffiness of the eyes, Bad Headaches.....Loss of interest, vitality... Very upset not advised by Paediatrician of possible side affects, he strongly recommended, no medical instructions in the packet.. ...Searched Singular on the Internet it all makes sense now... Dr's etc, should have a duty of care to advise patients of possible side affects... These side affects are real & Singular should not be given to children, research has shown children's brains are not fully developed til early twenties, what sort of damage is this drug doing to children's long term physiological state.. I find this very disturbing & cannot fathom how pharmaceutical companies can 100% assure there is no long term harmful affects to children's brain from taking this drug.. I find it totally immoral and disturbing that companies take greed & profits over children's physiological & long term health. F 13 15 days

 5  Asthma We are experiencing NONE of the side effects claimed. My daughter is going on 13 and has been on Singulair since she was 9 or 10. She is now almost as tall as I am (5'2), she is developing normally in all other areas related to the female anatomy, I lost track of how often I have to buy her new shoes, etc.. In other words, zero stunted growth issues, zero anger issues, zero any issues detailed here. She works with a renowned Pulmonary on her asthma, who keeps a close watch on these things. I should also add that she takes this in the morning, with Claritin being taken at night. In fact, on our next visit, the Pulmonary is considering weening her off of it due to her asthma being under control and her believing she might be "growing out of" the allergies that caused the asthma in the first place. This is a child who stands close to my height and weighs all of 80 lbs. So she is built very petite to begin with. (the age and gender listed are for her) F 12 5 years

 5  Asthma None noticed or suffered yet My 12 yr old son, was prescribed singulair after asthma medicines were increased to maximum doses allowed for his age as his sporting activities brought on severe asthma attacks, he was fine the rest of the time. Since taking medicine (Sept 06) he has not had one asthma attack and plays football 5 times a week, his steriod intake was reduced, and his blue inhaler has not been used in anger, although I still make him take a couple of puffs before sport.

 2  Asthma Anger, frustration, angst, introversion, depression, fainting My son began taking Singulair when he was 7. We were warned about behavioral issues (ADD like symptoms, insomnia, irritability, etc.) and didn't really notice any change. We recently noticed that my son was hiding it and not taking it (chalk it up to being 12?). Oddly, this surly, angry, frustrated tween I've been dealing with for 2 years went away and my son is back to his silly, funny, not perfect but fun self. He's not as obsessive and introverted (e.g., hooked on video games) and is back out playing basketball with his brother, volunteering to help with his dad, etc. We thought, for a moment, he grew out of being a surly pre-teen. But no...the day we realized he stopped taking it (mid spring-flowering trees, of course), we asked, and he insisted it was an accident and took it in front of us. He fainted at school. Come to find out that fainting is a rare but side effect of singulair. Meanwhile, I add that together with this "normal" kid who is back in our lives and I realize that something happens pre-puberty where kids just don't process it the same. If your kid is on Singulair and you're noticing the "teen angst" -- consider it might be his meds. M 12 5 years

 1  year around alergies My son was prescribed Floniase and Singulair because he has terrible allergies year around- we began the medication and about 3 weeks or so my husband and i notice my son (he was 12 at the time) developed a tic disorder. We thought at first stress-spoke to him and he said not under stress. I didn't relate the meds at the time. He ran out of meds and it was awhile before i got a refill. All of a sudden the tic disorders stopped. I still didn't think it was the meds. I was focused on him possbily being stressed and not telling us. When i refilled his meds and just gave him the Singulair NOT the Flonaise - soon after the Tic Disorder began again! I immediately equated it to the Singulair made him stop and threw them away. I have reviewed side effects and I am convinced this was caused from that medication. Regardless of no mention of this possibility. It was a scary moment to see him uncontrollably blinking his eyes and jerking -he said he didn't realize he was doing it. I was told by his physician that this was not related, I am not convinced I am his parent I know my son- if all of sudden you as a parent notice a difference in your child PLEASE don't listen to anyone other than YOUR CHILD!!!!

 1  allergies eye and neck twitches My son just started taking this medicine last Thursday. So, its only been 7 days and yesterday and today I noticed he would turn his eyes all the way to one side or the other several times and then stop. I asked him if something was bothering his eyes and he said yes but he couldn't explain what the problem was only that he couldn't help it and couldn't keep from doing it. He was only supposed to take for a month to get through the spring pollen season here. But, I'm not giving it to him anymore now that I realize the singulair is the problem. I asked him how long his eyes have been bothering him, he said it wasn't bothering when he went to the doctor, but now it is. He's only 12 and has enough to deal with just being in middle school. He says he's been sort of embarrassed by the problem. I hope stopping the medicine will end the side effects. M 12 7 days

 1  asthma My 12 year old son was recently diagnosed with Asthma and was prescribed singulair. He rapidly changed in behavior, going from a happy, social kid to a depressed, sad, angry, anxious kid. He has mood swings, crying for no reason, sadness, says he doesn't care about having friends anymore, he doesn't want to live this way. Naturally, we were terrified. We could not understand what was happening to our son. Took him to the doc today and she took him off the singulair. I am praying that this will be the turning point for him. M 12 2 months

 1  Allergies Not sure if it was due to singulair but my daughter took 1 dose, that night I researched the drug as I always do when Dr. Prescribes something for my children, after reading about side effects I decided not worth keeping her on it to see if she would get them, day or so after the dose she suddenly wanted to quit gymnastics team she's been on for three years, when asked why she would say I don't know and start crying, one dose seems very small to cause symptoms but I really am wondering if possible, it's been about a week since she has taken it and yesterday she seemed happy after gymnastics class, anyone else notice symptoms after only 1 dose?

 1  Seasonal allergies HORRIFIC neuropsychiatric side effects that lasted months after ceasing drug. This drug is very dangerous and should NEVER be prescribed to children for seasonal allergies. The benefits do not outweigh the risks. Although the FDA has issued warning issues and listed neuropsychiatric side effects in the packaging, the medical community is generally unaware of these side effects and consider them rare. Unfortunately, they are not rare. M 12 3 weeks
