| 5 | Allergy | I didn't notice side effects other than it really worked for me. The only negative is the expense. I have to pay $65 a month - my co-pay. | F | 58 | 30 1X day | 3/15/2011 | 5 | asthma | None | It reduced my asthma attacks. | F | 30 | 1X day | 8/15/2012 | 5 | | 2/12/2006 | 5 | Chemical intolerance to fragrances | I did not realize I had side effects, but looking back after reading patient comments I realize that the insomnia and irritability, greatly reduced tolerance for stress, etc., may well have been side effects of Singulair. When I suddenly stopped taking Singulair the first time after about 8 months (because I left the environment that was causing my original symptoms), after a few days I developed truly crippling lower back pain, like a muscle spasm at the top of my hip bone. Was flat on my back in agony for a week. I recently started taking Singulair again, took it for 3-1/2 weeks. Then, after leaving the environment that caused the allergic reactions, stopped again. Now, a few days later, the muscle pain is returning with a vengeance. This time, I put 2 + 2 together and am fairly certain that this is due to sudden cessation of the medication, as I have never had back problems before in my life (55/f). Also, after reading all the comments on this and another site, am wondering i | F | 55 | | 6/17/2007 | 5 | Asthma | No side effects at all on Singulair. Generics cause wheezing and allergies | This drug has changed my life. Half an hour after taking the first tablet, I actually felt my lungs opening up, and for the first time in as long as I can remember, I don't think about my breathing. I can laugh, run, climb stairs, I've dropped my use of inhalers by half, and rarely need ventolin. The difference has been noticed by all my friends and colleagues. On the rare occasions I miss a tablet, I am wheezing within a few hours. Amazing, life changing drug. And although I didn't take it for allergic rhinitis/sinusitis, it has cleared that up too, and I have a sense of smell for the first time in eleven years. | F | 51 | 10mg 1X day | 12/16/2014 | 3 | F | | 5/7/2006 | 3 | ashtma & seasonal allergies | I have become extremely irritable and moody. In addition, I have experienced some sexual side effects. Basically I do not have any interest in it. | Also, I have had trouble sleeping and want to take a nap after I come home from work. | F | 49 | | 5/14/2007 | 3 | Allergies | I took Singulair for the last three years and experienced relief from my allergy symptoms. Unfortunately, the last time I took Singulair , two months ago, I started having horrible dreams. Every night I had graphic dreams where I was killed. I know, not fun. The bad dreams affected my mood. I was telling one of my coworkers about my allergies and the problems I was experiencing and he told me about the affect the drug has in some people. I stopped taking the medication, I am no longer having bad dreams, and I am back to my normal happy self. | 3 Years. Only had problems this time around (past two months) | F | 46 | | 4/14/2008 | 3 | Seasonal Allergies and IC | VERY Vivid Dreams - mostly in the nightmare category | While this med has truly helped my seasonal allergies and my IC symptoms - I am becoming quite concerned about the vivid dreams I am experiencing - I have been on this medication for approx. 2 months and all of a sudden the last 5 constant nights I have had horrible - nightmares - that are VERY vivid - Does anyone know if a delay in symptoms like this is possible | F | 36 | | 6/3/2008 | 3 | | 7/7/2009 | 3 | asthma | The Dr. put my daughter on this medication at age 2 after my daughter had respiratory failure due to reactive lung disease. I thought that it was a godsend as her breathing much improved and she was able to participate in simple activities like running after being on it for a month or so. At about age 4 she started having headaches, sore throats, neck pain, leg pain, stomach aches and nightmares. | I have had her in the doctors office several times over the last year for these symptoms and never got any answers or indications that the singulair might be causing these symptoms. I am furious! My sweet four year old has headaches all of the time and not one of the doctors mentioned that this could be a side effect! | F | 4 | | 9/13/2009 | 2 | to control asthma-inducing allergie | Extreme anxiety, worrying, and obsessive compulsive behavior | I am sitting here in tears because I have only stumbled upon this information and and will stop giving this to my daughter immediately. My daughter has always been somewhat shy and concerned about things, but within recent months, she has been having extreme anxiety, running back in to check the door locks, asking "what if...?" constantly. A babysitter's house was broken into and our friend's car was stolen recently, so I was attributing her worries to those incidents, but it's just gotten worse and worse. She has even cried a couple of times at school, which she's never done. Now as I read all these testimonies, I have to think it is her Singulair, and feel awful that she's been so affected by this medicine and that I had no idea it was the cause. She recently started Flovent, and her stomach has been hurting, so we'll probably try stopping that too and see if that helps. Thank you all for posting. | F | 8 | | 11/29/2009 | 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 | | 7/31/2007 | 1 | I find it interesting the 2 posts below this one. Both female, both on Singulair for "about" 7 yrs., both give Singulair a rating of 5 and both just about the same age. How Odd. If there are no side effects for "these" women then why look them up in the 1st place? Lets take a guess at what drug company she works for (I say she and not "they" with conviction). Just a thought. | | 5/2/2007 | 1 | asthma | caused seizure and confusion | F | 89 | | 10/2/2007 | 1 | I just have to say that after reading all of these reviews...WHY WOULD A DR STILL PRESCRIBE THIS TO ANY CHILD????? This drug should be taken off the market!!! My friend has her son on this and as I am reading this it is exactly what she is telling me he is doing....This is absolutely insane...No mother or father should have to go through any of this...Singulair is NOT for children...As it shows in most all of these reviews that it affects the persons whole being...Seriously think long and hard before you put your child on this medication. | F | 32 | | 1/23/2009 | 1 | stuffy nose constant cough | mood changes,headaches,night terrors,difficulty sleeping, temper changes | Can't believe this could be the thing that changed my loving funny happy child to a agressive child(daily) | M | 2.5 | | 3/31/2008 | 1 | allergies | vocal and motor tics | its a horrible drug and they dont mention tics when they perscribe it and the bottle does not say anything about ticks and guess what neather does the paperwork you get with the medicine its crazy there trying to make this otc i wish someone/allot of people would get together and file a suit against them for selling something and not labeling it the dr had no clue but the hospital was like oh yeah she's on sigulair thats a possible side effect stop taking it well my now 9 year old still has the tics cant go to a movie gets bitched at by teachers and guides on fieldtrips etc i took her off the meds and the tics have gotten a lil better but its still a daily problem for her and just sad that she didnt have this problem and now she does and the company who makes the drug takes no responsibility | 9 | 1X day | 4/30/2014 | 1 | Singulair Generic Name: montelukast Montelukast is a CysLT1 antagonist; it blocks the action of leukotriene D4 (and secondary ligands LTC4 and LTE4) on the cysteinyl leukotriene receptor CysLT1 in the lungs and bronchial tubes by binding to it. The cysteinyl leukotrienes LTC4, LTD4, and LTE4 are important mediators of human bronchial asthma. Leukotriene D4 is one of the leukotrienes. Its functions in the body are bronchoconstriction, vasoconstriction, contraction of smooth muscle, and increasing vascular permeability. Other leukotrienes that function in a similar manner are leukotrienes C4 and E4. Studies have suggested that LTE4 works through its own distinct receptor, and although one has not yet been discovered, research is ongoing to isolated and characterize an LTE4-specific receptor.[ Why would you allow a receptor to be Blocked when we don't even know what it is ?

I never made the connection to all the problems I have been having with him, until a friend of the family sent me this link. I read in horror the stories from other parents, the symptoms that their children were having mirrored that of my son. I was having such a terrible time controlling him, I didn't know what to do. He has been doing horrible in school, and is even worse at home. Without even consulting his Dr. I threw away his prescription of Singulair and Flonase.It has been about a week now, and I am slowly seeing some changes...for the better. His allergies are starting to come back full force, but I have no idea what to put him on now.I have been researching other allergy medicine web sites only to find that the side effects for many others are the same ( Zyrtec, Claritan, Benadryl) as well as many others. I hate to see him suffer but I have no idea what to put him on now. If anyone has any suggestions please | M | 8 | | 4/24/2008 |
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)
