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)

 2  For allergy induced asthma My 8yo son has been on and off Singulair for 3 years. The usual amount of time is 3 months and he tolerated well. This time he has been on it for 6 months and at hte 5month mark something started happeneing to him: vivid nightmares, obsessions, horrible thoughts (about death), thinking about hitting others, anxiety and crying and the list goes on. I am so glad i found this site. I took him off 4 days ago....slight decrease in symptoms. how long until he gets back to his old self? Does anyone know a time frame for this horrible drug to get out of a child's system? It breaks my heart to have my son suffer like this.... F 36 6 months

 2  To prevent asthma attacks. Very heavy sleeping, difficulty waking up in the morning, general fatigue, unusual irritability. I'd hate to think of how irritable this drug might make someone who isn't as laid-back to begin with as I am; I would not be the least bit shocked to find out it is a factor in more than merely negative thoughts. After learning of other users' side effects, I have decided to discontinue using Singulair. This drug should not be prescribed without serious warnings about its side effects. What if somebody who (unlike me) already has a short fuse and has many sources or irritation (perhaps difficult children?) were to be prescribed this drug without being warned of the possible side effects? I'm glad to hear that Singulair helps some users as much as it does, without giving them the negative side effects. It's apparently not the right medication for me, and my doctor apparently needs to learn more about the possible side effects. M 36 21 days

 2  Seasonal Allergies Intense headaches (Felt like someone was putting an ax through my head!), "fuzzy" head Didn't help the allergies enough to warrant putting up with the side effects. Stopped after 2 weeks and headaches subsided to more "normal" allergy related headaches. F 36 2 weeks

 1  Asthma I took both Singulair and Accolate which is in the same class of drugs when they first hit the market. I experienced tingling in my legs, visual changes, and memory loss. Everything but the memory loss resolved as soon as I stopped the drug, the memory loss gradually improved over a year or so but I'm convinced impacts me to this day. Clearly it wasn't worth the side effects, but the drugs made me 100% symptom free from my asthma. F 36

 1  allergies I felt extremely, extremely tired. It took an incredible amount of effort just to get myself out of bed. I had to fight to stay awake throughout the day and felt like I was moving through quick sand. It did clear up my congestion, but wasn't worth feeling like I wasn't participating in life. I went off after the second day and have returned to the land of the living! F 36 2 days

 1  allergies so tired, so hungry I just can't get over how tired this drug makes me. I can barely schelp around at work and today, my first full day on the drug, I took over a two hour nap. I also ate, like 5 meals today. It has just made me irrationally hungry. I'm stopping immediately. F 36 2 days

 1  Allergy related asthma Depression, fatigue, anhedonia. Have stopped for 2 days now and am feeling better each day. Also seemed to affect my 2 year old son who I am still breastfeeding but that might be subjective based on my general grumpiness while taking it. Seemed to make him more apt to cry over little things and to affect his sleep? I will have to wait a little longer as I have only stopped for 2 days so far. F 36 10 days

 1  sinus infections and allergies In my son: moodiness, agitation, trouble sleeping, extreme restlessness, and trouble focussing. He got the 'fidgets' to such a degree his teacher is baffled. Also has heightened sensitivity. In myself: A worsening of my asthma, moodiness, anxiety, migraine headaches (the like of which I've never experienced), and sensitivity. My son and I have both been on Singulair for about two months. My son began to be restless, almost manic. He has a hard time sitting still now, and can't concentrate on what you're saying. His teacher noticed the difference about five weeks ago and said I should take him to the doctor (thinking ADHD, no doubt). I didn't think of the drug correlating with his symptoms until now, when I went over the dates. My side effects were a worsening of my asthma. I was taking it for my allergies, but my asthma had died down to where I had even let my inhalor expire; I never needed it anymore. Soon after being on Singulair I began having asthma attacks again. Lately it seems I'm using my new inhalor every other day. Also, I have noticed a change in my general feeling of wellbeing--I have anxiety and fits of depression that are unusual for me. I am taking both myself and my son off this drug, and hopefully our symptoms will go away. Please, if you have had adverse reactions to this dru F 36 2 months

 1  Sinus Rhinitis Depression, suicidal thoughts, nightmares, insomnia, irritability, constant PMS type symptoms, migraines (sick migraines - puking), dizziness, nausea, forgetfulness, anxiety, rapid heartbeat, exhaustion, loss of interest. I started it in May 2007. I had PMS type symptoms all through May and June. I couldn't stay asleep at night - would wake every hour or so and then take 2 hours to get back to sleep, then wake up an hour or so later. When I did sleep, I had horrible nightmares. My blood pressure shot up (it was already borderline since last year! 140/90). My heartbeat last week was 112 beats per minute. My blood pressure was 155/111. I was irritable, suicidally depressed (it was like it told my Cymbalta to take a hike!), exhausted, had anxiety attacks, and dropped weight rapidly (I've lost 22 lbs in 8 weeks). I don't know if the weight loss was because of Singulair, or because of Lean Cuisine, but I've lost 22 lbs. I stopped taking it on July 6th, 2007 and I'm almost back to normal. They really need to take it off the market. It's no good. F 36 2 months

 1  Breast augmentation/scar tissue Increased anxiety which I now know is directly related to the weight gain I have experienced. Sore muscles, to the point I had to go get a massage thinking it would help. Insomnia, as I couldn't stay asleep for more than 4 hours. I wasn't even prescribed to take it for alleriges/asthma. My doctor recommended I take it because I had breast implants and I delevopled scar tissue. Singulair has shown to decrease the chances of this happening. F 36 3 months

 1  Asthma Dramatic mood changes / extreme aggression My 8 year old son has been diagnossed with depression and is on a mood stabilizer and anti-depressant. After several painful months of trying to figure out what was going on and how to help him cope. We FINALLY got him to a place where he could control his behavior, emotions, and just be a happy kid. Then he was diagnossed with Asthma and was put on singulair... Now we are seeing extreme rage and anger in him once again. The only changes was by adding this medicine. The psychiatrist and pharmacist both said adding this medicine to the two he is already taking should not have any effects on him. If they only lived in my house?? I don't think they would feel the same way. F 36 3 weeks

 1  allergy induced asthma Took while pregnant due to worsening asthma symptoms. Made me very emotionally numb, detached, angry, impatient, full of rage and hateful! I lost my visual depth perception and developed bad neck swelling with headaches. I also noticed it made my breastfed baby colicky and sedated. I had the WORST withdrawals from this medication including EXTREME anxiety and panic attacks! I hope to God this hasn't left me with permanent damage or hurt my baby since I took it while pregnant!

 4  Allergies Nightmares!! Soooo tired! So far this has worked for me. I have had severe allergies since I can remember. I mean sneezing for 30+ minutes straight without stopping bad. This has worked well but the nightmares are horrible. I am going to start taking it during the day instead of night. Although it makes me really tired .. I will take tired over nightmares anyday. At least I no longer have to carry a shop towel around anymore to blow my nose on. M 37 14 days
