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  For Asthma I am an Australian woman in my early 50's. I was prescribed Singulair by my doctor about 2 years ago. I have suffered from severe depression, nausea, muscle aches and pains, aggression and the list goes on...... I have asked my doctor about these problems over the last 2 years and she says "I'm menopausal". I have just read an article in a magazine about the shocking side effects of Singulair and this product should be taken off the market immediately. Because of the dangerous side effects of this drug, no doctor should be prescribing this medication to children. I have stopped taking Singulair about 3 weeks now and I feel like my old self again. My asthma is bad and I'm allergic to all puffers but I'm not depressed anymore and that's a blessing. F 52 2 years

 5  Chonic asthma Terrible nightmares, leg cramps, muscle aches, flu like symtoms. Singulair is wonderful except for the side effects. I took it for three years and had to stop because of bad dreams. I started taking again and got leg cramps, muscle aches and flu like symptons. I stopped for a few weeks, symptons were gone. Started taking it again, symptons returned. Now that I read comments about Singulair I see other related symptons such as low back pain, concentration problems, forgetfulness. I have been off for two weeks now. I'll see if other symtons get better too. F 54 3 years

 5  chronic sinusitis, asthma none. All my life I have had severe headaches and infections from my chronic sinusitis and I developed asthma in the 5th grade. I used to sleep all the time and I counld'nt really function in everyday life. When I started taking singulair practically all my problems vanished. The only bad thing is when I forget to take it my asthma comes back with a vengence and I can hardly get out of bed because my sinuses are in such bad shape. F 17 10 months

 1  seasonal allergies; asthma Prescribed for allergies and slight asthma by our pediatrician for our 5 yr old son. He started acting like a completely different boy-temper tantrums where he would scream and cry uncontrollably-he had such a wild look in his eyes. He became violent and once hit me and bit his older brother. He said he didn't understand why he was so angry or crying so much. He also became afraid of the dark and wanted to sleep with the light on. After 2-3 weeks I couldn't take the emotional rollercoaster anymore. His mood would change so rapidly all I could think of was Dr. Jeckyll and Mr. Hyde at which point I remembered the news report that the FDA was investigating the connection between singulair and teen suicide. I decided to check for other side effects too. When I found this website it was like reading about my own son's erratic behavior. I just wanted my sweet boy back and I got him back within a week of being off singulair-the difference was amazing. I just wish doctors would infor F 37 3 weeks

 1  Allergy and exercise induced asthma Anxiety, depression, moodiness, irritability, low self-esteem, reduced sex drive, racing negative thoughts, reduced motivation to do things I normally love to do, emotional "melt downs", reduced ability to cope with small problems, enhanced PMS symptoms, etc, etc, etc! I am normally a very upbeat, optimistic, funny person, and have been my whole life. After 2.5 years on Singulair, I no longer felt this way. Because the changes were so gradual, I truly believed that something else was wrong with me, i.e. that the symptoms I was experiencing were not drug-induced. I thought that I had inherited the propensity for depression from one of my parents and that the time had come for me to start anti-depressants. I even went so far as to consider having my doc prescribe one for me! After my husband told me of the link between Singulair and suicidal thoughts (which I did not, thankfully, experience) and reading the postings on this website, I decided to stop taking the daily Singulair (10mg) and Zyrtec (5mg) which had been prescribed for my asthma and allergies. After about two days of a real funk (withdrawal) and two weeks of extremely itchy skin (Zyrtec withdrawal) I began to feel like my old self. Happy, laughing, able to cope with things, not menta F 47 2.5 years

 1  asthma stomach aches, hitting, uncontrollable screaming, tantrums, loss of appetite I am so hurt. As a mother I trust what the doctors prescribe for my child. I am so grateful I found this website soon. My two year old son has been prescribed this medication for a month now. After about two weeks on Singulair, he started screaming uncontrollably. His cousins were suddenly afraid of him hitting them with something. He experienced more tantrums and a loss of appetite. As I recall now, there have been several times where he came to me and complained of a stomach ache. I am completely horrified but again thankful I found this website very early on. I am taking him off this stupid medication today! M 2

 3  Mild Asthma and allergies My daugther was diagnosed with mild asthma at age 5. By age 6 she was started on chewable singulair and eventually moved up to the 10mg tablet. She has progressively gotten sicker with time. Not her asthma, but with these crazy symptoms. She was diagnosed with migraines at age 10. For the last three years her quality of life has declined so that she has only had one or two good days a week. She completely missed the last semester of the 11th grade and will have to repeat it. Her symptoms have been: headaches (cluster, migraine and mild), leg pain, rapid heart rate, chronic fatigue, rash like psorasis on her elbows at times, severe abdominal pain, nausea and vomitting, occasional nightmares, foggy thinking, hunger, and reflux, mood swings and abnormal periods. She was recently diagnosied with sub-clinical hypothyroidism. She has started on Sythroid and after a month has shown some improvement. I took her off the singulair about 2 weeks ago after finding this site and reading about all these side effects. I don't know if the singulair is the total culprit or not but, I took her off of the Singulair to see. It may have been what has caused the sub-clinical hypothyroidism also. She has been on it for years and progressively gotten worse. She has had mutliple GI tests that have turned up nothing but this could have been the reason all along. We have been to about 14 Doctors total with the various symptoms including her Pediatrician, Pediatric Gastrointestinal Specialist, Neurologist and Allergist. She has much improved over the last couple of weeks and is starting to act like a normal 17 year old. I had even started her in counceling 6 weeks ago because of the depression she has experienced from being sick all the time. She has not had F 17 11 years

 1  asthma/ allergies Increased eating and weight gain, about 25 pounds. Extreme emotional changes. Anger and agressivness. Unable to concentrate, grades in school went downhill. Increased bruising and sensitivity. Numbness. Unable to sleep, waking up constantly. Crazy and sometimes disturbing dreams. Rashes, scaly skin, and itchyness. I would not reccomend this drug. It helped me very slgihtly, but not enough to have to deal with all the changes it made to me and my life. F 17 10 months

 5  allergy-induced asthma None I, and my 4 year old son, are highly allergic to oak pollen. Before Singulair, I was on inhalers and he was on albuterol, xopenex, pulmicort, prednisolone, you name it. This year, on Singulair, *not one breathing treatment* was required. It has worked wonderfully for both of us. No problems at all. Today his Allergist refused to refill his prescription 'and see what happens' and now I am just waiting for the asthma attacks to start.... F 38 2 years

 5  Asthma none Singulair changed my life for the better! I have had none of the symptoms others have had - depression, weight gain, etc - but I HAVE had those on corticosteroids, which are the only alternative to this amazing wonder medication. Yay Merck! F 42 10 years

 1  ALLERGIES My son is two and was taking singulair for about 1 year. He has not slept a full night not even once. About 3 months ago I decided to take him off of it and about a week later he had a "febrile seizure" so the docs called it. I put him back on it because I thought his allergies caused his fever and got sicker from being off of it...Well 2 weeks ago I wanted to try him off it agian because I hate him being on all kinds of medicine. Within a week of being off it, he has had 7 atonic seizures (where he just falls down for a second). I truely believe his body is withdrawing from this awful drug..It is odd that it has happened each time just within a week of being off this "miracle drug". My son has no other problems. We had to see a neurologist and he just wants to put him on more medicine and says it is no way realted to sinuses or singulair. I beg to differ. I think the doctors and drug company's are just interested in helping each other and not our children... I am going to trust God and listen to my intuition as a mother and a christian. M 2 1 years

 5  Allergies & Asthma No side effects experienced I talked to my doctor about the "New" warnings. I do not experience depression or suicidal thoughts on Singulair. So I am back on Singulair for this allergy/asthma season. I have experienced no side effects. I take Singulair in the morning. It has once again relaxed my breathing and totally improved my performance. If allergies seem bad on any day I will also take and Allegra 60 in the evening and that works very well. I have only needed my Albuterol 1 time since April. F 49 2 months

 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

 1  inflamed airway Anger,racing thoughts of paranoia, began to feel as I did when first diagnosed with depression which had been under control, but the Singulair seemed to be overriding the Wellbutrin. I also withdrew from my husband and did not "want to be bothered." All side effects went away with 36 hours of stopping Singulair. F 61 4 days

 3  allergies and asthma None except I can't fall asleep when I take this stuff. Does an amazing job quelling allergic symptoms and asthma, especially for my cat allergy. But it does rev me up at night so I only take if dire need. F 54 3 years

 1  allergies, asthma Spaced-out paranoia feeling, nausea Yes, there is an FDA "warning" right now (if link not pasted, visit FDA site) http://www.fda.gov/Cder/drug/early_comm/montelukast.htm. What gets me is how they are quicker to recall a stupid toy but drugs go out there till they do God knows how much damage. I ma trying something radical; homeopathy. When I follow directions exact, I seem to get some relief; I still use Zyrtec for bad days, as well as inhaler for emergencies. I just got so tired of all the damn side effects I'd rather suffer some allergy symptoms than feel like a zombie. F 42 6 days

 3  asthma Same as others, change in behavior for the worse. Mood swings, unhappy and sad, irritable, biting, kicking, tantrums, biting finger and toe nails. Worried about all asthma meds my son is on. After starting singulair, things were increasingly worse. I noticed changes when he was first diagnosed with asthma and was given albuterol and pulmicort and prednisolon. His mood changed immediately and drastically. He became a fearful, spastic, nervous, easily set off little boy. Then he began Singulair and things were even worse, within 2 days he began nail biting and having tantrums, head butting and biting and was over excited at odd times. Once he began Nasonex, I thought I should take him to a psychologist, began exhibiting what I thought were autistic behavior, withdrawn, repetitive behavior. After reading this site, I am wondering if these meds are the culprit that changed my once happy, cheerful, very laid back little boy. Singulair was successful in eliminating his usage of albuterol, no attacks since, he is virtually asthma free with all the meds in the "athsma capital" that we live in, but I want alternatives, n M 3 1 months

 1  Allergies Tics, facial and eye swelling,lack of appetite, stomach pains, nightmares, OCD tendencies, uncontrollable screaming bouts sometimes lasting an hour My Grandson is one of the children who has experienced these horrible side effects. In the two months that he has been taking singulair, I have watched my daughter and her husband become increasingly terrified at the changes in our happy loving little boy. I am urging each and everyone of you to contact Merck and the FDA and file a complaint in order to stop this drug from being used in children. It is one thing as an informed adult to take a medication with potential side effects, it is a totally different thing for a parent to give a medication that they have been led to "Believe" to be safe to their child. There is strength in numbers and if we all contact the news, Merck, FDA, any one we can think of and inform them about what is happening to our children on this drug, we will be able to stop other potential victims from experiencing what our families are going thru....Please I urge you to continue to spread the word about this drug - tell everyone you know. Remember, Mer M 3 2 months

 1  Asthma/Allergies Nothing at first, then hallucinations with sounds followed by bad dreams; finally he couldn’t sleep alone. My child acted as a normal 3-year-old, so at first I didn't suspect Singulair. Then after taking it for a few months, he was afraid to be in bed alone. Now recently he can't even sleep by himself. After reading other kids' reaction I decided to take him off. Please research the affects before giving a child ANY medication. M 4 8 months

 1  1st for Asthma, then for allergies Depression, moodiness, loss of libido, loss of interest in hobbies, life etc. After hearing that Singulair was linked to people committing suicide, I decided to stop taking it. Without doctor supervision (I would not suggest doing that), I went off it cold turkey after being on it for 7 to 8 years (I 'quit' around the end of March). I used to feel 'frozen' inside -- not temperature-wise, but emotionally. It was scary to get all this feeling back in just a few days. I've been happy for the first time in many, many years. Unaccountably happy. I had thought the emotional problems were related to circumstances and aging, which might have had a contribution. But I am on other medication that seem to be controlling the asthma and allergies and see no reason to go back taking Singulair. The change for the better in my emotional state has been dramatic and I want to stay this way. F 50 7 years
