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)

 4  Severe Dustmite Allergy Not sure what all is actually for sure from this drug, but I have been non-stop hungry since I started taking it. I've had to make myself eat less, and I have still gained weight. I usually always stay at the same weight, but gained 4 pounds with Singulair. This is not normal for me, as I rarely gain so much as an ounce, plus I've had to eat less, and still gain. I can get depressed/anxious, but I think it's just my life....it kind of sucks right now for reasons beyond Singulair. I sleep better when I take it though, and I take it at night. I have noticed more indegestion. I seem to get colds/bronchitus/asthma less than I did before, but I don't know if it is because of this drug, or because of the Allergy Shot Therapy I am on.

 2  asthma and rhinitis Was great for the first week or so but then things went downhill. Until I found this website I thought it was me. I wasn't feeling "myself", waking up all night long with every noise almost jumping me out of bed, having anxiety attacks, heart palpitations and loss of appetite. Works great on the rhinitis. Wasn't sleeping well and switched to taking it days which improved my sleep some but heart palpitations and anxiety attacks too much to take. F 38 3 weeks

 3  asthma Fatigue, loss of appetite so I actually gained weight, sores on my gum, my husband told me I sounded angry all the time,feeling aggressive, irritable and moody. After about 18 mos. on it, I suddenly developed an allergy to aspirin (it gives me an asthma attack.) The huge benefit was that my breathing was never better than it has been my whole life, without the jitteriness I get from the inhalants. I do not take Singulair daily any longer because of the side effects, but use it sporadically if a cold induces my asthma. F 48 1.5 years

 1  Seasonal asthma Depression, anxiety, unable to cope with school, fear of being alone, body tics, deep sadness My son has taken 5mg Singulair for five months. We put his increasing depression down to the shock caused by three severe asthma attacks in five weeks, he had never had an attack before. Slowly his anxiety became depression, last week the doctor said he needed a psychiatrist. Previous to Singulair he was happy, now he just cries and wants to be at home. I am shocked by the change. Last week took him off Singulair, he has improved already, though has a long way to go. Thank you for this site. I will get a full blood test tomorrow. M 9 5 months

 3  airway reactive disease My child has been a terror since she has been on this med.(Aggressiveness,hitting, kicking,yelling,screaming). She never had this type of behavior before starting this med. It certainly helped the coughing and vomiting, but we will be discontinuing it now that I am realizing the behavior changes are not the terrible 4's. If your child's personality has changed do not hesitate to consider that Singulair may be the culprit. F 4 5 months

 3  Allergy induced asthma Night waking, trouble falling asleep for nap, irritable, more aggressive and active than normal My (20 month old)son has been on Singulair for a week now. The Dr. perscribed it for the chronic cough he's had for a year everytime he lays down. Today I started to wonder why he has been waking in the night and not taking his afternoon nap like normal. He's also been aggressive towards his teddy bear. So, I went online thinking there might be more to Singulair than I read in the leaflet. Wow, what feedback! The first night Singulair DID stop his coughing and he slept like a rock the first three nights. I was so excited because it seemed like he was finally going to get sleep without being interupted by coughing throughout the night. Yes, the drug works, but it's not worth the side effects, especially in kids too little to explain what they're feeling. I just wish I had found this site before I spent the $$$$ to purchase the blasted stuff! M 2 7 days

 1  Allergies / Asthma Extreme aggressive behaviour, hitting, kicking, yelling. Turned a wonderful little boy into someone we didn't know. His preschool teachers reported having to segregate him from the other kids because of his hitting all day. Normally a very loveable and affectionate child. Always high energy but while on medication unable to shut him down. Constant night terrors, wouldn't sleep for 9 nights in a row. Out of three physicians nobody informed us of these possible side effects. After weeks of no sleep and inability to calm him down we researched it on the internet only to discover that everyone else had experienced what we were dealing with. We are kicking ourselves for letting this go on for five weeks before we asked why he was like this. We thought it was the trying three's. He complained of a sore penis as well as a "belly ache" every night within an hour of taking the medication. He cried all the time and needed constant reassurance and wanted us with him all the ti 4mg at bedtime definitely improved his asthma and allergies. We were able to significantly reduce the need for his puffers but there is not a chance we would ever give him singulair again. He had his last dose 72 hours ago and we now have our little sweetheart back. He has his sense of humour back and loveable huggable nature. We will research everything we give him in the future before it ever touches his lips. Our family physician, the asthma clinic, and allergist immunologist are going to get an earful from us for not mentioning that these side effects were something to watch out for. Parents beware and ask questions! These little ones can't express themselves well enough yet to tell us what is really going on. M 3 7 weeks

 2  Asthma - Sinusitis - Allergies Nightmares, anger, anxiety, agitation, heart racing and jumping and odd feeling. This is the third time I've tried to take it; yes, there's *some* benefit for asthma, none for chornic sinusitis or allergies. But, I still need Advair every day and Albuterol. Doesn't do as much for asthma as it once did and it ALWAYS had distressing mental and heart side effects. My doc said those are not in the book but admitted other patients come in and say the same thing. I'm going off. F 50 12 months

 3  Asthma and Allergies Severe headeaches at times, bad nightmares My 6 yr. old daughter has been taking this for 2 1/2 years now and I have mentioned the headaches to the doctor and asked him about Singulair and he said it probably will get better, and to keep her on it. She still has headaches at times and bad nightmares. My 5 year old son was prescribed this 4 days ago and has broke out in hives, so now I think I will take them both off of it and see how they do. Thank you all for your information. F 6 2.5 years

 1  doctor recommended for asthma CHRONIC HIVES BIG WELTS ALL OVER MY BODY, SEVERE NIGHTMARES, HEADACHES, ITCHING ALL OVER, DEPRESSION, BIG WEIGHT GAIN, BEWARE WHEN TAKING THIS DRUG YOU MAY GET CHRONIC SIDE EFFECTS LIKE ME?I was having problems with breathing for the first time in my life. I had to go to the ER about 3 different times in about 2& 1/2 weeks. They had started me on prednisone and an inhaler. The 3rd time in the ER the on call doctor was concerned and wanted to admitted me. My husband thought he was helping me out and said lets get to the bottom of this. They did and an other doctor said to take singulair and continue taking the prednisone. That is when everything started. It has been a nightmare for me. I stopped taking the singlar but have to continue taking the prednisone to control the CHRONIC HIVES I get daily. I have had a CT scan, lots and lots of blood work. They have not found anything. I can not get off the prednisone because the hive get really bad. I am now going to a specialist who is going to try some cancer drugs to get me off the prednisone which I have been on for 6 months at 15mg a day and am getting side effects from it. Some days I don't know how I can make it through the day. But I try and I keep Praying. My husband has told me that he feels like it is his fault. I don't blame him. But he has to watch me go through this daily and it's tearing him up not being able to do any thing.( My husband which he could go back in time and never let them admit me.)After about two months I stopped the singular.

 3  Asthma CHRONIC HIVES, vaginal discomfort- itching, soreness, raw. Hallucinations- Hearing distinct noises that jolt me awake, sound of sliding door opening and someone coming into the house, someone calling my name, someone screaming a shout at me, seeing things, sometimes vivid dreams, tightness in eye cheek area tension face, different and strange type of headache, ITCHING FEET! I have infectious asthma, which means that I get asthma once I get sick, I also have hyper active respiratory disorder, both are so bad when full blown that I fear dying. Singulair helped me control my asthma, cutting the time it took me to get control over my airways from 3 months after an illness to about 4-6 weeks. I was so satisfied with the results I would take claritin to control the chronic hives, from head to toe all day long. However the vaginal dryness, inflammation, itching etc. is too much to bear. I will have to stop using this drug. However I would continue it if I did not have this side effect, tolerating most of the others including the chronic hives an d hallucinations. F 40 9 months

 4  Asthma Fatigue,sleeplessness,high blood pressure,anxiety,memory loss,dry skin,mild depression,diarrhea,weight gain,hair loss,the start of kidney failure. Started taking singulair about 9yrs ago when it first came out. Did wonders for controlling my asthma and still does to this day. Recently starting reading a book about natural cures. Decided to make a list of all ailments I have and preceded to do some research on there causes. Did a search for Singulair side effects and came across this site. What an eye opener. Of the 14 ailments I have written down. 11 of them can be attributed to the extended use of Singulair. I am going off this drug immediately to see if it is the cause of most of my ailments. Thanks to everyone who contributed to this site. M 42 9 years

 2  allergies My 2 1/2 yr old son became a COMPLETELY different child w/in 3 days of taking this medicine. ANGRY, MEAN, would cry for everything, nothing made him happy. While his allergy symptoms improved, my sweet little boy turned into a very unhappy child. He fought taking his naps, cried for every little thing such as getting in the car or putting on his shoes. Everything became a battle. I wish I would have found this site before I gave him his LAST dose tonight. M 2 5 days

 2  Allergic rhinitis/chronic sinusitis At first I was thrilled - finally a wonder drug for my allergies! After a few weeks, I started to get really itchy, especially on my hands, around sunset every evening. Large red splotches would appear on my chest and neck. When I would scratch, welts would raise. As I continued to take the medication, I developed increasingly severe welts in response to the slightest skin trauma. It got to the point that I would have huge welts that would leave scars along the waistband of any of my pants, and I couldn't let the edge of a sheet of paper touch me. I stopped taking Singulair, and worst of the symptoms were gone in a few days. It took about six months for the last of them to totally disappear. This stuff SCARES me! Very disappointing.

 5  Asthma/recur Asthmatic Bronchitus None; however my ears "ring" but that started after more than 2 years of using this drug so I doubt that's it. Did notice I can't eat almonds anymore (mouth hurts), though -- maybe it's the analgesic effect since you can't take asprin with Singulair either! Wow! Terrific drug that saved my life! First got it when I had four (4) pluersies in my lungs while using Advair prescribed by my regular doc. (Advair/Serovent -- dangerous drugs). The Urgent Care doc suggested I use Singulair instead along with my rescue inhaler for acute stage. Presto! I got better. Now, I'm on it full-time and rarely use my rescue inhaler except if I get standard Bronchitus (from the kids). F 47 4 years

 4  asthma Terrible abdominal pain and constipation. Two visits to the ER, 2 cat scans and a hydoscan later, and I suddenly started to think about this drug, and how the terrible constipation seemed to have started near to when I started taking it. NONE of the many doctors I've seen---my regular doctor, the gastroenterologist, the surgeons---ever considered it could be the singulair. Now that I've read on this site that several others have experienced the same side effect, I'm going to stop it and see if that's the culprit. I'll be sorry to have to stop it, because it's been very helpful for the asthma and I've had no other side effects. F 44 3 months

 1  exercise induced asthma My 3 year old daughter is normally a very laid back and pretty quiet child. SHe's been on it for 8 days, and the past few days she has been out of control and completely out of character. Bouncing off walls, throwing tantrums, and not listening at all. I will be taking her off this now. Especially after hearing there is aspartame in it. F 3 8 days

 5  Formerly unmanaged asthma So far, none. That is HIGHLY unusual for me! I have spent the better part of my adult life being tired and having asthma symptoms (long undiagnosed). My asthma was not diagnosed until I was in my 30's, and no doctor ever really managed it correctly, or at all. I kept on believing that my breathing wasn't too bad. After becoming progressively tired over the past year+, I told my primary care doctor that we needed to find out what was wrong with me, that I couldn't go on feeling the way that I was feeling. A full cardiac work-up revealed a perfectly functioning heart. The pulmonologist's report wasn't as rosy. He believes that my years of untreated asthma have caused some permanent damage, and that there may also be COPD involved. He put me on Advair and Singulair. I decided on taking 5 mg. of Singulair rather than the prescribed 10 mg, since I'm less than 5' tall, and under 100 lbs. I'm frequently given doses of medication that are too high. Well, I can't say for sure which drug is doing what, but I do know that I have not F 50 10 days
