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  Allergies SEVERE Depression, Bronchitis, Constant Cold Symptoms While taking this drug, I became more depressed than I've ever felt in my life. I have always been a happy person, but I was feeling so down when I was taking this. I was also constantly sick, developing colds, bronchitis, etc. I felt SO much better after I stopped taking it. It did not help AT ALL, in fact, it made my immune system weak and my moods horrible. DO NOT TAKE. F 23 5 months

 1  Allergies I suffered from a sever anxiety disorder and agoraphobia from taking this medication. It took doctors over three years to finally discover that Singulair was what was causing the anxiety. I also know four other people who have had the same problem. One of them hasn't left their house for three weeks because their anxiety is so bad. DO NOT TAKE THIS MEDICATION! F 23 4 years

 1  Seasonal allergies Severe hives on my legs each evening. They start out small and then after an hour or two, the welts grow and cover my entire thigh. Can sleep for 15 hours at night and still wake up tired and needing a nap. Helped with my allergies, no sneezing or runny nose...but the hives are far worse than my allergies ever were. F 23 6 weeks

 1  Allergies Our daughter was prescribed this drug by her pediatrician at 7 yrs of age for seasonal allergies. Within the first week she was having intense nightmares and then began experiencing mood changes, intrusive and suicidal thoughts and ocd, as well as severe abdominal pain over the next few months/yrs. Before taking this drug our daughter was an extremely happy, healthy child without a trace of any of these aforementioned conditions. We questioned our pediatrician multiple times regarding Singulair as the cause of the symptoms, which he dismissed. We kept her on the drug because of this and for the fact it helped with her allergies - for 2 yrs. This was back in 2005-2006 before the black box warning was issued. Our daughter is now 23 yrs old and has lingering side effects from this poison including intrusive thoughts, ocd, nightmares and abdominal issues. She has managed these through therapy, ssri's, watching her diet and continued support from her family. We still regret the day we ever It seems some have taken this drug with little to no negative side effects. After countless hours of research we have found that perhaps one reason is due to a correlation between montelukast and a mutation in the MTHFR gene (which our daughter has) affecting folate and B vitamin assimilation.

 5  Allergies & nasal polyps Absolutely none. Allergic symptoms have decreased and my polyps have shrunk in combination with nasal spray therapy. A lot of people commenting here are doing what patients on a new drug often do: attribute every negative feeling and symptom they're experiencing to a drug they recently started taking. Singulair did exactly what it's supposed to do for me, with no side effects, and I will gladly continue taking it. Don't let the hypochondriac comments here discourage you from trying it.

 3  allergy related asthma attacks drymouth, stomach pains, drowsiness (even when taken at night it stays with me most of the day), some leg cramping Was perscribed this medication to help with hay fever that was causing asthma attacks and heard from many people that it was a miracle drug for those with similar issues. The first week I was on the medicine I was also on Predisone, which had its own terrible side effects. I can definitely breathe easier now, but my stomach pains have become worse adding to my issues with acid reflux. F 24 60 days

 2  severe asthma mood change, depression, loss of sexual appetite Works great on my asthma-- but really messes with my mood. I thought it was just me... It is not. They need to retest this drug for side effects. F 24 6 months

 1  Asthma Unusually long bleed times - so much that my Hemorrhoids would cause embarrassing stains. General feeling of being emotionally flat... cloudy, muscles easily fatigued. Bleeding that easily can't be healthy. The side effects I experienced are NOT fictitious or confused with some other pre existing ailment. I definitely can not take this drug. I'm jealous of the people who can take singulair. I know dealing with asthma would be much easier if I could tolerate the side effects. If my asthma was absolutely life threatening, I'm still not sure if I would take it. To each their own. M 24 4 days

 1  allergies mood swings, aggitation, weird dreams, extreme drowsiness, chest tightness, emotional breakdowns I already am a bit of an emotional person, but when i was on this it felt intensified x10. I was SO tired i literally could barely drive. I went from eating healthy and working out 3x/wk to just shoving food in my mouth 24/7 and laying on my couch at ALL times possible! very STRANGE dreams, unable to wake up in the morning, felt like i was drugged. allergies were better but experienced chest tightness instead. very easily aggitated and would just completely flip out on people when i normally wouldnt. did not want to be around anyone. stayed secluded and would not conversate with anyone. im a very outgoing talkative run-around type and people seemed shocked when they saw how quiet i was.. had atleast 6 friends ask me whats been wrong with me..

 1  Shortness of Breath Memory Loss, lack of concentation I was prescribed this drug at a trip the ER for shortness of breath. I think I got the catch all "athma & allergy" diagnosis. I don't think my shortness of breath was related to this, so I can't speak for how the drug works. In the short time I was on it however, I did experience memory loss & lack of concentation. I would be getting ready to say something & it would just completely slip my mind. Or I would try to remember something I was supposed to do and I just couldn't. I felt like I was losing my mind. I wouldn't recommend this. F 24 8 days

 1  Son taking it Worsened depression horrible anxiety doesn't want to leave house. Made his sleep issues worsen. In the last year he gained a lot of weight while having insomnia which turned into an eating disorder. He was always so thin. This is the worst medication for anyone in hides the real problems of what is making him have allergies , sinus infections and asthma. It has helped his sinus infection. But he still needs inhaler. I am trying to convince him of the true facts of this medication and what it is doing to his life and state of mind. Now I'm afraid the side effects regarding his heart when he goes off of it. Please discontinue use of this medication. Please have a site on how to discontinue use of this medication without side effects. M 24 3

 5  Severe allergies None I love singulair. It has saved my life. I'm severely allergic to dust mites, mold, cat and dog dander. I couldn't breathe at night. I was always wheezing and coughing. I could never go to my sisters house because she has 2 dogs and Every time I went my allergies would flare up and I would wheeze and sneeze . I take Zyrtec and singulair every night before bed and I just can't complain. I sleep well now! At first I did get strange dreams but never nightmares and the best thing is I can finally breathe!! I've not had any wheezing or sneezing episodes since then. F 25 6 months

 5  Asthma Nothing but good things. This has been a life changing drug on my part. I almost never have attacks, I can exercise and have lost 5 pounds already because i am able to exercise. I have a raised libido and have miraculously been in the greatest of moods. My only worry is long term affects. I wonder if i will truly be able to not worry about my asthma for as long as i am on this medication. M 25 45 days

 5  severe allergies, asthma hyper, like I've taken a caffeine pill (which I have actually enjoyed because I'm happiest when I'm chatty and moving); strange, vivid dreams but nothing scary or anything So far so good. Taking Singulair with Nasonex, an antibiotic, and Albuterol inhaler as needed. Has helped so far, which is a relief b/c nothing else was, I have had years of allergies and asthma; Zyrtec, Allegra, Allegra D, Sudafedrine, Claritin, never helped. Benedryl helped but it puts me to sleep and I have two young children to keep up with so Singulair seems to be the miracle drug for me :D ...so far F 25 3 days

 5  asthma Greatly improved asthma symptoms. I went from needing albuterol daily to barely at all. Allergic rhinitis improved too. I can definitely tell how well it works since when I forget it for a few days, I become a wheezy, snotty mess with itchy eyes. Wonder drug for me. Completely changed my life. F 25 12 years

 5  Sneezing Slight headache and makes me tired. I take it at night so it helps me sleep. Huge plus I used to take Claratin D for my allergies that I have gotten the past year or two. It worked but not well. I remained stuffy when I went outside. I ended up having to go into surgery to get polyps removed from my sinus cavity's 3 weeks ago. My DR put me on Singular to help relieve the sneezing and to help relieve my allergies for the spring/summer {I didn't know that even in March there is pollen in the air coming up from either the south/west}. I am happy about getting singulair it means that I won't be suffering this summer; for the first time in about 2 years. Hopefully it will help reduce the build up in my sinus cavities also. Along with that I was put on nasonex at the same time. F 25 4 days

 4  Severe Dustmite Allergy Not sure what all is actually for sure from this drug, but I have been non-stop hungry since I started taking it. I've had to make myself eat less, and I have still gained weight. I usually always stay at the same weight, but gained 4 pounds with Singulair. This is not normal for me, as I rarely gain so much as an ounce, plus I've had to eat less, and still gain. I can get depressed/anxious, but I think it's just my life....it kind of sucks right now for reasons beyond Singulair. I sleep better when I take it though, and I take it at night. I have noticed more indegestion. I seem to get colds/bronchitus/asthma less than I did before, but I don't know if it is because of this drug, or because of the Allergy Shot Therapy I am on.
