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  Asthma My 7 year old daughter was prescribed Singulair for asthma, 5mg once daily. After one week on the drug she began waking up in the middle of the night, and after 2 weeks she began experiencing sudden and severe side effects - including depression, inconsolable crying, bad thoughts, paranoia, anxiety, obsessive thoughts (obsessed with food’s expiration dates), low self-esteem, and fear. When asked why she cries and says the things she says, she cannot explain it. I spoke to the pediatrician about this symptoms and he had never heard of them and dismissed my concerns, he even said it would be the first time this happened to someone in Latin America; he also questioned my “internet sources” when I told him I had done research on the internet and explained what I found out about the drug. We stopped the Singulair after a month of taking it. Now it's been 7 days since stopping the drug and she's slowly recovering. Furthermore, her new Pediatrician agrees that Singulair This shouldn't happen to a child; this drug shouldn't be prescribed to children at all. This has been a horrible experience for my daughter and my family. F 7 30 days

 5  allergies/chronic sinus infections none I plan to drop my use of Singulair because of all the current negative reviews about it. I also take flonase and allegra (generic of both) and I hope these two drugs will "hold" my allergies in check. F 66 5 years

 2  Chronic sinus infections Extreme anxiety, obsessive compulsive behaviors, extreme hypochondria. I have always been an anxious person, but never to the point of having negative thoughts about myself and those around me. I suffer from extreme hypochondria now, to the point where I am going to the doctor once a week for even a small, minor pain. I still have sinus infections! F 19 2 years

 1  allergies Severe depression, mood swings, aggression, lower muscle pain, nightmares, poor concentration If you are thinking of putting your child on Singulair...don't do it. Our daughter was on it for 3 months and the side-effects were so severe that we were considering taking her to therapist. She immediately started complaining of leg pain, and then the nightmares started. Within a month, her personality began to change and she became very violent and sometimes depressed. We didn't even recognize her anymore. She has been off Singulair for 3 months now, and she is back to being herself. She can sleep again and her pleasant nature has returned. Singulair was a nightmare for us! F 4 3 months

 1  chronic asthma I had given this med to my 4 year old son since 06/07. We started experiencing negative side effects about 3 months ago. He was weepy, clingy, irrational, and mean at home. Things he normally loved to do, he began to be afraid of and have anxiety over situations. I saw on the news FDA was investigating this drug and I immediately called his pediatric pulmonologist. I feel uncomfortable giving this drug to my child. As of today, I have discontinued use of singular. We will see if his behavior improves. I am praying that it does. M 4 10 days

 1  Allergies Mood swings, temper tantrums, aggression, irritability, nightmares, and poor appetite. My son started taking Singulair to combat repeated ear and sinus infections. At first, there was no noticeable change in his demeanor until recently. In the last several months, his mood changed and we were at a lost to explain the aggression and irritability. We were told about the recent studies and found this website and immediately took him off the medicine and noticed an immediate change in his demeanor. We had our happy, easy-going son back.

 5  Asthma, allergies None. I've had asthma my entire life, and it wasn't until my doctor put my on a regimen of Singulair and Advair that I was able to life symptom free. I take one of these and a dose of Advair every morning, and I'm symptom free. The only negative thing I could say about Singulair is that I get asthma REALLY bad if I miss it, or run out. This makes me think I'll be taking the med for the rest of my life. (That's scary to me.) M 22 4 years

He experienced many problems nothing was ever linked to the medication. I was told he may have ADD and depression.he hasn't taken it for months now and his mood has changed drastically,has better focus in school.

 1  Chronis sinusitis and Asthma sadness,mood swings I thought the enveloping sadness and sudden mood swings were a sign of aging until reading an article from a Canadian medical research team that indicated that those same symptoms were often side effects of Singulair. F 64 1 years

 1  Allergies My teenager was on this and became severely depressed on it (no prior history). Took him to his doctor and she said she had never heard of this as a side effect. Said if he didn't snap out of it, she would put him on an antidepressant (which I am totally against). Took him off the Singulair and he returned to normal within a few days. I find it interesting that now there are reports of this drug causing depression/suicide. Glad I didn't listen to the doctor and knew in my gut that this drug was making him feel this way. Watch your kids carefully while on this drug! M 14 7 days

 1  allergies Had severe acid reflux. Had no idea it was linked to this medication. Took this medication for 3 years and I stopped taking it because of the cost and noticed within a week the acid reflux was gone. I had been taking 40mg of protonix twice a day and it did not even help. I had never had any problem in all my life, not even gas or burping. This was a horror!! F 72 3 days

 1  Cough-Variant Asthma My 4 year old son experienced Tics while taking this medication (blinking his eyes, shaking his head, opening and closing his mouth, clearing his throat, making a sqeaking noise). Once we took him off the Singulair, it took a few weeks,but we did notice an improvement with his Tics (he had never had Tics prior to his taking Singulair). He was also taking Albuterol - maybe it was a combination of the drugs, but honestly, it was the scariest thing we ever encountered with our son. In observing him for a 15 minute period, he would shake his head 25 times (and it was a violent head shaking - like that of a dog shaking off water) and open and close his mouth 6 times (like he was trying to unblock his ears). He seemed to constantly make the sqeaking noise. It has been almost 3 months since we have taken him off of Singulair, and it appears that the TICS are finally gone. I would NEVER recommend this drug to anyone - it caused such stress and trauma in my family. We talked to 4 separate doctors, and only one doctor agreed that in his opinion, the Tics were triggered by Singulair. I do believe that my son was probably genetically pre-disposed to Tics, but absolut M 4 6 weeks

 1  Allergies and Asthma Aggressive behavior, temper tantrums, nervousness, anxiety, depression, hair loss, hyper,moody,unusually tired in the mornings. My now five year old son was prescribed this medication when he turned two. Approximately 6 months after taking it, his entire demeanor changed. He turned into a very moody, angry, sad child and started losing his hair. The pediatrician, allergist, immunologist,dermatologist, and specialists all said that it could not be the medication causing his hair loss. He now has no hair at all. Recently, I have found links to Singulair and hair loss and I am ANGRY. My child has been treated for Alopecia for now 18 months and this terrible drug could be the cause. As soon as I found the connections to his behavior changes and hair loss I took him off the medication. It has been three days now, and I have already noticed a modification in his agressive behavior. Parents should be aware of the harmful affects of this medication. M 5 2.5 years

 1  seasonal allergies Severe drowsiness, almost falling asleep while driving. Mood shifts, anomie, lack of enthusiasm about life, laziness. It was very hard to attribute this to the drug because it takes a while to start, but it alleviates quickly when drug is stopped. No noticeable relief of allergies: possibly got a bit worse. Stopped taking it a week before the news reports started. I do not think this drug should be widely prescribed. I would never give it to a child too young to express themselves clearly, would monitor carefully for behavior changes over a time frame of weeks, and would avoid starting at the same time as other drugs. None for me thanks. M 53 1 years

 5  Asthma Myself-None Daughter-None I am 29 years old and had been on steroid inhalers since I was a kid. I have been on Singulair for a year and after a month I found I did not need the steroid inhaler anymore. I take a 10mg a day and 10mg loratidine and it is like I do not have Astmha or allergies. My 5 year old daughter was diagnosed with Asthma last fall and has also been on Singulair since. I have not noticed any side effects in her. Of course she expresses dark thoughts sometimes but who doesn't. Most of the time she is happy. Even if I found it was causing mild depression I would probably keep taking it; it is so great to live without asthma and without the side effects of the steroids. M 29 1 years

 3  Asthma excessive/rapid weight gain, thirst (especially in afternoon), some anxiety, trouble focusing on tasks I am so relieved to have found this web site. I saw an article in the news today and did some research. My daughter has gained an unexplained 10 pounds in less than a year (without gaining much in height like you would expect for that kind of weight gain in a child) & she is a very healthy eater for her age. She eats virtually no trans fats, drinks no fruit juice/soda, swims twice a week, plays basketball, softball, etc...I can't believe that Singulair could be responsible. The worst part is she worries about being heavy & I keep telling her she will grow out of it. It could also explain her anxiety and trouble focusing (which I attributed to her age). I'm going to take her off today & see what happens. Her asthma is not completely under control anyway and we are seeing the doctor in a few weeks for more options. How scary. F 9 18 months

 2  Allergy Induced Asthma Mood swings, irriatiblity, sleeplessness, night terrors, Ear infections, clingy, hitting sibling. We added this medication to his asthma routine as he would have a persistant cough that sounded like a seal for the allergy seasons. Well, I noticed an increase of mean behavior toward his sister, he was waking up persistantly throughout night. Would wake up with night terrors and not know who I am. TOOK forever to calm him down. He also turned from an easy going kid, to a defiant child and also very disturbed whiny kid. Took him today to doc for ear infection, which has increased since putting him on this medication. I am NOT giving him his dosage tonight. My son is normally a sweet boy, but has since been turned into a monster! Thanks for all the comments! You helped me determine it's not just in my mind! M 3 3 months
