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  Allergy related asthma Depression, fatigue, anhedonia. Have stopped for 2 days now and am feeling better each day. Also seemed to affect my 2 year old son who I am still breastfeeding but that might be subjective based on my general grumpiness while taking it. Seemed to make him more apt to cry over little things and to affect his sleep? I will have to wait a little longer as I have only stopped for 2 days so far. F 36 10 days

 1  sinus infections and allergies In my son: moodiness, agitation, trouble sleeping, extreme restlessness, and trouble focussing. He got the 'fidgets' to such a degree his teacher is baffled. Also has heightened sensitivity. In myself: A worsening of my asthma, moodiness, anxiety, migraine headaches (the like of which I've never experienced), and sensitivity. My son and I have both been on Singulair for about two months. My son began to be restless, almost manic. He has a hard time sitting still now, and can't concentrate on what you're saying. His teacher noticed the difference about five weeks ago and said I should take him to the doctor (thinking ADHD, no doubt). I didn't think of the drug correlating with his symptoms until now, when I went over the dates. My side effects were a worsening of my asthma. I was taking it for my allergies, but my asthma had died down to where I had even let my inhalor expire; I never needed it anymore. Soon after being on Singulair I began having asthma attacks again. Lately it seems I'm using my new inhalor every other day. Also, I have noticed a change in my general feeling of wellbeing--I have anxiety and fits of depression that are unusual for me. I am taking both myself and my son off this drug, and hopefully our symptoms will go away. Please, if you have had adverse reactions to this dru F 36 2 months

 5  Asthma (my 3 y.o. daughter) None My little girl struggled for the first three years of her life with bronchiolitis, finally diagnosed with persistent asthma. She had poor control, esp. when sick, until Singulair was added to her daily treatment plan. Since then, we have not had one ER visit, she sleeps peacefully, and even when she is sick, she does better. I am very happy with how well she is doing on this. M 35 8 days

 5   I had little side effects. Headaches and trouble sleeping. I had truly the worst asthmna a that a person could have. I was in and out of the hospital and at one time, I spent 11 days in intensive care on a respirater. My lungs were failing. I was given my last rites and at 28, I was dying. When I finally got better, my pulminoligist put me on Singlair. It has changed my life. For one thing, I have a life now. I have a child and I am happily married. I believe from all the readings that Singulair is toxic in children. I can only speak for myself and it saved my life. F 35 7 days

 5  asthma and allergies No side effects noticed There are three of us in our family that have used Singulair. My daughter used it when she was 5-7 years old for her asthma. She had no side effects. She had cold weather induced asthma and it really helped her. I have used Singulair for the past three autumns for rag weed allergies and it has been the miracle drug for me. I had tried everything and nothing would help. When I took Singulair, my allergy symptoms completely went away. I also have a five year old son who takes it in the spring and summer for allergies. We had tried everything and nothing would help. Again, Singulair really worked with no apparent side effects. My only complaint about this drug is that there is no generic available and it is very pricey. F 35 3 years

 4  asthma, allergies Potentially, weight gain and hair loss I read all the comments on this site and can't believe all of the small children who are taking this med. READ THE LABEL! This is not recommended for children.....but I digress. I'm researching this med as an adult and am reading all of these horror stories but can only find negative comments on side effects with children. I am 35 and have taken this med for approx. 3 months. I am wondering if this nagging itch in the back of my throat (especially at night) and hair loss are symptoms that have been experienced by ADULTS. People, doctors are people too! They are humans. You are capable of making your own decisions and doing your own research before giving your helpless child a medication. They even make it easy for you! They put it right in the side effects paperwork they give you when prescribed! I digress again. I like this medicine. It has helped the symptoms I took it for but have seen one or two comments on hair loss and weight gain on this drug. I'm looking for any ot F 35 3 months

 4  Asthma/allergies Heart palpatations, anxiety, irritability, agitation, anger, possibly high blood pressure. Both my 6.5 yr old son and I are now off it. He also had some of the above symptoms and has been very hard to live with, my sweet little boy has been missing since June. While I gave it a high rating b/c it did help my asthma, I am actually very disappointed by the drug. Only by reading this website did I realize my symptoms coincided with going on Singulair, everything started within 2 months of starting it. I am now on a high blood pressure med. AND prozac for anxiety, but I really think it's the singulair that caused it all in the first place. I stopped taking it as of last night and already feel better today. Much happier and relaxed! I haven't been angry at my 2 yr old daughter all day...and that's a great feeling for me. I'm hoping going off it will help my son in the same way! F 35 10 months

 3  for chronic sinus infections I didn't know that they were side effects until I found all of the other people on this site talking about the same things I was experiencing. Crying uncontrollably for small reasons, moodiness, depression, anxiety, focusing problems. The biggest one for me...weight gain, which only ads to the depression. I have gained about 10lbs and a huge belly, I look pregnant. And frequent nausea and upset stomach. I stopped taking last night before visiting this website, feeling the weight gain might be a side effect. Now I realize that it has a whole long list of side effects I hadn't even thought about. I hope to feel better soon. I would rather live with the sinusitus than this. Would never take it again! F 35 30 days

 2  seasonal allergies abdominal pain; restlessness; pens and needles in my legs; insomnia; night terrors!!!! Singulair did fix my allergy problem, but I DON'T CARE!!!I'm so glad the lightbulb finally went off in my head as to what could be wrong with me. Death to Singulair!!! I just figured out today that Singulair is most likely what's been causing me all my discomfort. I hope today is the last day of this hell I've been going through. I will not be taking Singulair anymore--I just hope the side effect symptoms cease tomorrow!!! F 35 30 days

 2  Rhinitis lethargy, sleeplessness, cloudy head, stuffy nose, dry throat I actually went to a local pulmonologist as I suspected I had exercise induced bronchoconstriction / asthma. I'm active in cycling and running and have always been hypersensitive to colder weather and get SOB/tightness in chest when exercising for long periods. After watching a news clip on the condition I did some research and decided to make an appointment. This is the first time I've been in a doctor's office in years and I felt great going in, just wanted to see if I could improve my riding and extend my season by getting treatment. They determined I did have EIB and rhinitis which he said could contribute to the problem (I haven't noticed any symptoms though). He gave me Proventil for immediately before strenuous exercise and Singulair to take every evening for the rhinitis. That night I took the Singulair and slept normal. The next morning I overslept and did not want to get up. This is not like me. My head was stopped up and my throat dry. Again, I don't generally suffer allergi M 35 3 days

 2  Asthma and allergies Helped with asthma and found it had more impact than regular steroid inhalers for me. But I started having terrible night terrors where I would wake up in a fright and sometimes find myself on the other side of the bedroom. I stopped taking the singulair and they stopped. I can't say for sure whether the two were linked but they seemed to be. I would like to take it again to help my asthma but the night terrors were too bad. F 35 2 months

 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

 1  allergies rage, suicidal/homicidal thoughts, mood swings, loss of concentration, hyperactivity My 6-year old son was prescribed singulair for allergies. On the third day of taking this drug, he became an emotional wreck. He was so hyper, seemed out of control of his body - literally bouncing off the walls. Grandparents and friends even noticed the change. He became extremely frustrated because he could not concentrate on any task, game, etc. Very unlike him. THEN he started talking about wanting to kill people, and himself. I was beyond shocked and scared. At first, I didn't even think of contributing it to Singulair, until I started researching side effects. I was outraged. I took him off of it immediately and he was back to himself within 24-48 hours. A week after this experience, I received some health alert email about the psychotic reaction dangers of singulair to children. It is terrible to think of a "simple" allergy med causing such a scary and life-threatening reaction. I warn everyone I know with kids, just in case, and one of my friends' sons is experiencing similar problems. F 35 3 days

 1  allergies rage, anger, no concentration, yelling, trouble at school My 8 yo has only been on this med for less than a week but he is getting in trouble at school for not doing any work at all. He got caught putting scissors in his mouth and threatening to cut his tongue out! This is when I snapped and thought it had to something new going on. This wasn't my child. F 35 6 days
