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  Son taking for allergy management Just now taking my 6 year old off of Singulair, despite Pediatrician recommending continued use. Within the last month, he has become extremely agitated, grumpy, weepy, miserable. Complaining of stomach aches, very tired, not a happy camper. I strongly believe it's the singulair and will not put him or my other children on this medicine again. Seemed to work fine for the first year of use. Did seem to help with asthma/allergies for a short time, then the effect seemed to lessen and the side effects worsened. M 6 2 years

 1  allergies and asthma severe anxiety, hallucinations, unable to sleep due to terrifying dreams, self-harm behavior, sadness, agoraphobia, separation anxiety My son has been on Singulair for 4 years now and is 4.5 now. On April 22, 2011, he developed severe separation anxiety, agoraphobia, hallucinations, severe sadness, self-harm behaviors, and difficulty sleeping due to terrifying dreams. Over the course of three days we were in the emergency room 3 times due ot this behavior. On the 3rd emergency room visit, he was admitted to Helen Devos Children's Hospital. Doctors were baffled at his behavior using Ativan, Versed, Haldol, and Risperidone to attempt to help. We had to put restraints on him as his symptoms increased in intensity to keep him safe as he was trying to bite off his fingers, scratching at his skin, and banging his head. He had brain scans and an EEG. He was seen by neurology, psychiatry, infectious disease, toxicology, etc. After being hospitalized and with no relief from the anti-psychotic medications for 3 days, a psychiatrist found infomation on the internet about psychosis in children who were taking Singulair. With no answers yet, and nothing else to do, she tried taking him off of the drug. With in 3 days, he was back to normal, and happier than ever. He's been off the drug for 12 days. He has had 3 episodes of anxiety attacks since then, but nothing like he had in the hospital. Are you going through this too? PLEASE contact me! M 4 4 years

 1   Mood swings, anger issues, hyper behavior, not listening, excessive crying. My 6 year old started taking this to help with a cough he has as a result of chronic pneumonia. Within a couple of days we noticed extreme mood swings. Over the next week or so we watched our even keeled child lose his temper and cry. He wasn't listening and seemed to be bouncing off the walls. He was miserable, not worth the side effects. F 6 2 weeks

 1  Allergy induced asthma My 16 year old daughter took the pill and the very next day she was over the top angry, aggressive and full of rage. She was put on singular on a Wednesday and I took her back to the doctor on Monday and they immediatly took her off singular. I did not make the connection immediately but her behavior made me take a second look at the presicription side effect label from the pharmacy. F 16 5 days

 2  First time seasonal allergies Increased anxiety; nausea, made worse by anxiety, which caused decreased appetite; itchy/scratchy throat which I believe was from Singulair, not allergies. I had never had seasonal allergies much before that I was aware of, but I had been having a lot of "colds" where I'd feel run down and have sinus issues. My doctor told me they were seasonal allergies, and prescribed me Singulair. I did notice a little decrease in sinus issues, especially at first, but not even an amazing improvement. I have a history of mild anxiety, but the past 5 days it's been way worse and different than my anxiety before. I'm 99% sure it's from the Singulair. My throat has also been really scratchy, which I don't think is from the allergies since it didn't start until I started Singulair. I'm stopping Singulair and for now I guess I'll just stick to using a neti pot, which I would recommend to anyone with sinus issues by the way. F 18 7 days

 1  Allergies Acid Reflux, Nightmares, Eye Twitching, Nervousness, Anxiety The very first night I took it, I experienced several different vivid, bad dreams. I looked up side effects and found that bad dreams were a potential side effect, although the pharmacist tried to assure me that it must have been a coincidence. I have had several restless nights and bad dreams since. The acid reflux has been horrible and doesn't stop even though I've taken Nexxium, Tums, and Maalox all at the same time! The eye twitching has also been very annoying because it's non stop! I will stop taking Singulair. F 46 3 weeks

 1  Asthma I tried giving Singulair to my 7 year old daughter twice and both times she woke up in the night with severe hallucinations. She was screaming at the top of her lungs, as though she were tied to a railway track and a train was coming. She said that the bed was flipping around and that the blanket was flying all around the room. She was holding her ears and pointing at things in the room (that weren't there) and screaming "Mommy make it stop!!!!". Her heart was pounding out of her chest....it was just terrifying. From this experience and from what I've read, it seems very mind altering. It has only been around since 1998, so the long term effects are unknown. Very scary. I will never give it to my child again. Her brain is much too precious. F 7 3 days

 1  Allergies irrational behavior, ADHD like sypmtoms, anger, aggressiveness, night time fears, anxiety Our daughters symptoms GREATLY increased in severity after taking her off for a week and putting her back on Singulair. We were to the point of taking our previously "normal" child to a psychologist for testing. Our older daughter happened to catch the warning label which prompted us to take our 7yro off the drug. Her behavior has dramatically improved. The irrational behavior, anger, aggression, night time fears are now gone. She has had a very rough year in 2nd grade after having 2 excellent years in KG and 1st. We are absolutely thrilled to have made this connection. Thank you to all who have shared their stories. You made a huge difference for us as this was the first information I found and the stories were so remarkably similar it made a huge impact. Thank you!! F 7 13 months

 1  Allergies Please do not take this medication. I feel terrible that so many of you have felt so ill but happy that I'm not the only one. I stopped taking this medication 2 days ago. Taking this medication has completely changed my personality behavior and character. I became aggressive, angry, intolerant, impatient, I can't sleep and if I do I have horrible violent dreams, I hallucinate, I obsess over nothing, I start fights with loved ones or completely avoid them. I have no compassion, empathy or emotion towards anyone. There are too many negatives to type. Taking this medication could get me fired from my job and divorced if my husband wasn't so understanding. I got my first speeding ticket in 14 years after taking this medication for 2 weeks. I would rather have a sinus infection for the rest of my life than take this medication for 1 more day. F 34 2 months

 3  asthma aggressive, hyper With the winter thaw, my 5 year old son gets a terrible dry cough every year for about 2 months. I had him on steroid inhalers last year, but took him off after he become so aggressive he tried to choke me several times and he was still coughing quite a bit. I then tried Singular. He was not as aggressive, but very hyper on the 4mg I was prescribed to give him, but the coughing completely stopped. So I decide to experiment a bit. I HALFED THE PILLS and then HALFED them again so he was taking 1MG. Worked like a charm. Not as hyper and no aggression and it was just enough so that he didn't cough at night. My gut was that his little body couldn't handle the high dose and why not try and cut it down? Singular also has a red dye it in that some children have really bad reactions to. Perhaps that could be the problem as well. An alternative to that would be to be prescribed the adult dosage and cut it right down. Adult dosage does not have the red dye in it (the red for the 4 and 5mg is because it's a chewable for children). I think I'll try that next year and see if I can see a change. It's only for a couple months and I now give it to him RIGHT before bed so I don't have to see the instant change in him. Somehow my little dude falls asleep. Otherwise, he's running around like a banschee! M 5 2 days

 5  Chronic allergies, sinus issues Slight dryness and/or irritation of the back of my throat on occasion. May be allergy rather than med related. This medication has done wonders for me. My allergies greatly reduced and I only need a single mucinex for occasional mild congestion. A cold has gone around our family recently. Previously colds+allergies= awful sinus infections. I don't have one and my cold symptoms are easily managed. It's been night and day and I'm thrilled to be on Singulair. F 30 14 days

 1  Asthma joint pain, mood swings, weight gain, unexplained phobies It took a lot of research and over a year to determine the side effects were from the medication as all the side effects were so different. eventually after many trips to sports medicine for my joints and the doctor for my unfounded new fears i traced everything back to the same time i started the medicine. ALL side effects were gone within 2 months of stopping use. Please, do not take this medicine. it is scary what it does to people. M 32 1.5 years

 1  Chronic Congestion None My son has responded well to Singulair. He asks for it, himself, because it helps both his congestion and to clear his brain fog, which helps him focus in school. I am, very unfortunately, going to take him off of the drug after discovering it contains ASPARTAME. I have no choice, and I am gravely disappointed in this company for putting poison in a medication which is greatly needed by so many people. M 8 5 months
