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)

 3  allergies slight drowsiness, dry mouth, dried out sinuses similar to what a cold or flu medication will produce Was as effective as Zyrtec and Chlor-Trimeton, but not as effective as Claritin in clearing out my sinuses. Singulair doesn't work well enough for me to deal with the minor side effects, especially when there are other drugs (Zyrtec and Chlor-Trimeton)that have no side effects for me. F 25 1 days

 3  asthma, chest and nasal congestion i took my first 10mg dose after my doc. visit at 10 am this morning. got home 30 minutes later and took a nap before work and had a really vivid strange dream and remembered it clearly. i never remember my dreams, maybe a few times a year i'll remember one. and then at work all day i was dizzy and nauseated, still a little nauseous now. hoping these side effects will go away. i'm noticing less congestion already and my wheezing isn't as bad, i could also walk longer at work without being out of breath and speak long sentences without feeling like i was out of breath, which wasn't the case for the past few weeks.

 3  allergies/asthma (due 2 indoor mold WEIGHT GAIN, CONSTANT HUNGER, FATIGUE, TIREDNESS, WEAKNESS, INABILITY TO CONCENTRATE, LACK OF MOTIVATION I am very careful about what I eat - healthy diet - gain weight regardless and never feel full. I am tired 24/7 even though I get a full 8 hrs of sleep per night. I have trouble waking in the mornings and usually don't feel like doing much of anything. I go to work and sometimes struggle with simple instructions or can't carry on conversations intelligently due to lack of concentration. I'm just too tired and hungry most of the time to focus on anything else. I've tried working out to boost my energy levels, but most days I can't work up enough pre-existing energy to do so. I tried vitamins, but they bothered my stomach along with the singulair. I have seen amazing improvement in my allergy symptoms and have not had to use my inhaler for asthma in months. Before Singulair, I was prone to catching colds/flus frequently but have not been sick much while on this med. However, I am too young too feel so weak, and can't live with the weight gain (about 15 lbs.). Therefore, I am going off the medicine. I recommend this prescription to allergy/asthma sufferers without the side effects. F 25 6 months

 1  Allergies Night terrors,thought of hurting myself, others and even my puppy. Became very paranoid about things or being someone I wasnt. side affects can last 4-6 weeks. I had to go on an anxiety medication to get me through. I'm currently on my 5th week and things have improved greatly. I would have what I would call snap shot images or thoughts. Possible things I've seen in the past to movies. Best advice I can give is have someone that can give you a lot of support. Luckily my mother is still around, she had to tell me on several occasions to take my anxiety medication because it was as though I would be in a different world. Also set up an appointment with a behavioral type doctor. I learned the hard way that neither my family doctor or the ER doctor had the knowledge or know how to deal with this dramatic reaction. If your not religious now would be a good time to start believing because this experience was one of the worst things I have ever experienced. If you are currently going through M 25 5 days

 1  Mild Allergies (Headaches) Pain in left leg on the upper inner thigh I went to the doctor to figure out what could be the cause of persistent headaches everyday. My doctor prescribed me montelukast being that I don't take any allergy medicine. I've taken the medicine for 2 nights and on the second night my left leg got so tired and I had a restless night because I couldn't get my leg to stop hurting or feeling tired. 4 days later I cannot walk without my left leg hurting nor can I lay down without it hurting. When I try to stretch it out it causes more pain. I do not recommend this medicine to anyone. F 25 2 days

 1  Adult severe allergies Horrible time sleeping. This is only the third night taking singulair. My doctor told me to take it at night so I have been...My sleep has progressively been getting worse. Last night I woke up about every hour. Totally uncomfortable in bed and moving around a lot. After reading others' comments about this drug I am going to discontinue Singulair. What a waste of a copay! F 25 3 days

 1  Allergies I had my FIRST HUGE panic attack EVER on this drug. I have taken many different types of anti-histamines before Singular, and although Singular seems to help the allergies... I will not take it anymore after the past four weeks! I had another panic attack and went to the ER it was so bad. I didn't have anxiety before Singular, now I'm on meds for it. Also, I constantly feel out of it, get staring spells and am ridiculously tired. This is the complete OPPOSITE of who I was before Singular. Worst decision to take it. I wish I would have seen this site before taking Singular. F 25 4 weeks

 1  Asthma Behavioral Changes, Altered Mood, Turning into a maniac, Minor Depression that resolved after stopping. You should not take this medicine. I can't believe they even give this to kids. I took this for two years to control my Asthma, and it made me insane for those years. It altered my brain function and made me feel mildly depressed and hopeless, Made me lose my judgement and I could not make sensible decisions at all, It also made me do things that I regret now. If you are considering, or your doctor is considering prescribing this drug for asthma, there are better options available that won't make you insane. M 25 2 years

 1  Allergies before i found this site i was wondering what was going on. the doctor prescribed me singulair nasonex and allegra D for my allergies. None of the drugs helped my sinus. i took singulair for 7 days last month and it didnt work so i stopped taking it. this month i decided to give it another shot since my sinus congestion has been horrible. As i started to take it again i noticed following: i have a huge anxiety attacks, panic attacks and mood swings. i though it may be just because i have been stressed out. well as my wife says i became hypercandriac (however you spell it). talked to the doctor he said anxiety is common prescribed me XANAX and some anti depressant. by no means i am depressed and sideeffect of antidepressant are insane. so untill i looked at this site i never made a connection between singulair and my attacks. i will keep everyone posted in 1 week from now how it goes. stopped taking singulair april 23, 2012 giving it a week and seeing if my anxiety/panic attacks will go away. Xanax will not be used unless in case of major attack M 25 7 days

 1  allergies Severe constipation, bloating, weight gain (went from petite 5'2" 110 lb to 150 lb despite diet and extreme exercise of all kinds), brain "fog", sadness, extreme fatigue (every day I felt like I could just sleep for DAYS) I tried going to doctor after doctor convinced I had a thyroid problem or something. All tests always came back normal! I'm not sure why I didn't make the connection but I just realized all of these problems started at same time I started singulair for seasonal allergies. I don't think my allergies were even that bad and I am angered that no doctor ever told me it could be that. They all tried to make it seem like I was crazy and must be sitting in front of the couch eating and not exercising. I've been severely depressed because despite a reduced cal diet, eating healthier than I ever have, and hours of exercise a day (starting running on my lunch break, joined a gym, took martial arts classes 3x a week for 2 hours at a time!, even got a personal trainer!!) and NOTHING worked, I just kept gaining! I finally stopped about 2 weeks ago and I am starting to feel better. The fatigue is almost all gone, it's a night/day difference! I am hoping the weight will come off. For those who had similar problems and stopped singulair, how long until the weight comes off? I'm desperate to lose at least 30 lbs to get back into all of my old clothes! F 25 3 years

 5  Chronic Rhinitus/Sinusitis nasal drippage I LOVE THIS PRODUCT! I'm 26 years old and have suffered from sinus infections as long as I can remember for several times a year. These infections used to get so bad that I would get bloody nose several times a week as well. I used to be teased as I would carry a whole box of Kleenex with me to school. I haven't had a sinus infection in the 2 years that I have been on Singulair (10mg). It's heaven. I'm trying to get my dad on it as well. Having a slight runny nose is NOTHING compared to the pain that I used to be in. Thank you Singulair! F 26 2 years

 4  asthma I took Singulair for 3 years and have finally stopped it. I will say it did help, but the side effects were scary once I realized what the med was doing to me. At first, I thought there were no side effects and the medication DOES work very well for asthma. After 3 years, I finally realized that it caused panic attacks an anxiety. I also believe it has caused me to gain about 10-15 lbs. Once getting off, my body went through withdrawal (allergies flared up and I felt tired). I'm taking Allegra until those symptoms clear. Also, for you ladies out there, I really believe that my Loestrin (low dose birth control pill) is helping my breathing. We'll see what happens. Works well, but has hidden side effects. F 26 3 years

 3  Asthma I was on this drug for 18 years. Never had any side effects until the last two years. I had tremors for 2-3 years and doctors weren't sure why. Finally, last year, my doctor and I deduced that it might be from Singulair. I decided to stop taking this medication after being on it for 18 years. Within a few days, my tremors subsided. I have been off Singulair for a year now and I haven't had any tremors ever since. It is very strange that after 18 years, I developed tremors from this medication. F 26 18 years

 2  Severe asthma heart palpitations, anxiety, achy muscles, restless, awoke at night every hour, fear of the worst happening. Asthma symptoms improved greatly, but side effects are intolerable. This is what it must feel like to do cocaine. Very upsetting to hear about the children that are having terrible side effects, heart goes out to you parents for your children. F 26 3 weeks
