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)

 5  Asthmatic for 18 yrs/Allergies Drowsiness I came to this site looking for side effects of another medicine I'm taking and decided to see what people have said about Singulair. I was put off at the fact that someone said the only reason anyone would give this a 5 is because they work for the drug company. WELL, I certainly do not. When first prescribed, I was taking the chewable child dose (considering I was about 9) but eventually moved up to the adult 10mg dose. I've never noticed any side effect except drowsiness - which is why the bottle says to take at bedtime. It works wonderfully for me. I notice whenever I skip a night my asthma flares back up to usual symptoms and I have to take at least one dose of my inhaler. When I take it as prescribed I don't need my inhaler at ALL. It does take about 2 days for Singulair to fully work if I have missed some doses. F 21 12 years

 5  Asthma/Allergies None that I notice. I have been taking this drug since I was about 11 or 12, and has helped me to live a normal life. I had a gap in insurance coverage a couple years ago and went without for about two weeks. I noticed how much this drug helped me. It relieves the tightness in my chest and my throat, and I don't cough like I did. I did notice on the package a few weeks ago that this was not recomended for children under the age of 12... that might be causing the problems with all of these children whose parents have commented. If the doctor perscribed it anyways, well, it may be time to find a new doctor. F 21 9 years

 2  allergies The worst insomnia imaginable(it's 5:01 as I write this and I've been trying to sleep since 10:30p), and a fatigue headache to match. Pretty much unbearable. Have noticed slight reduction in allergies but not enough to rival the sleep loss. Oh well. Might also mention I am taking the generic form of the drug. F 21 6 months

 2  allergies,asthma worsening of asthma, more frequent asthma attacks, mood swings, change in personality, depression, sleeping issues My doctor prescribed this medicine for my allergies and asthma. Within 2 weeks my asthma worsened. I was having more frequent attacks and my overall breathing went down hill. The more I tried to sleep, the worse I felt. On top of that my moods began to change quickly and without much reason. There were multiple times I would snap and be verbally combative with my boyfriend with little or no prompting. Other times I suddenly felt very sad without being to pinpoint any reason and could not hold myself together. Crying bouts and inability to deal with fellow employees at my workplace sky rocketed. The mood swings and freakouts also contributed to more asthma attacks. Before taking Singular I had been aware that it had some negative side-effects in children. I had no clue that adults had also had problems with it. I have no doubt this medication works well for some people. According to the labeling most people can take this medicine and reap the benefits without negative side effects. For those of us that it does NOT help, it's a very serious matter. I have discontinued use TODAY after my doctor realized something was wrong after the my last meltdown. F 21 1 months

 1  Supposed Asthma Extreme depression, Feelings of hopelessness, sudden absence of motivation, strange dreams, possible halted growth. No painful physical side effects. I'm 21, been using this drug since my teen years. Never could quite figure out what the hell was wrong with me, always feeling down all the time, weak, and empty. At 19 I stopped using this drug after a bit of research. Felt renewed and alive, and more energetic during my workout sessions. I'm no doctor, but having used this medication may have stunted my growth. I was always the tallest in my class back in middle school, and now it seems i'm stuck at a measly 5'7. My sincere suggestion to parents is to avoid the use of this drug... Even if it may have avoided the presence of my asthma, my teen years are gone forever, my youth had no significance. Spent it dwelling on worthless thoughts and now i'm trying to make up for lost time... still hard to do when painful memories still lurk within. And I could be wrong to say this, but cardiovascular exercise along with a frequent lifting regimen has greatly improved my overall health and physique, I'd say use pills as a last resort.

 1  Asthma Depression, anxiety, sleep disorders, decreased mood for many many years, weigh gain (unable to lose any weight), self harm. This medication has helped my asthma, yes.... but it is not worth the declining mental health and weight gain it has caused me.... the anxiety attacks, depressive episodes, weeks of staying up til 3 or 4 am from insomnia, the difficulty losing weight but overall the loss of myself and who I was before this medication is what hurts the most.

Highly don't recommend. I stopped taking it 3 days ago and already starting to feel better. Completely lost myself for about a week or two.

 5  Asthma After using singular for about 4 months I started not being able to fall asleep as easily. It took 2 hours to go to sleep sometimes. After about 5 months I became very paranoid, like someone was in my house. I also started experiencing night terrors. Singular worked great for my asthma. The reason I stopped was because of the mental side effects. F 20 6 months

 2  Asthma Palpatations, Myalgia, Insomnia, lethargy, weight gain, depression. Have been on this drug for a long time and the symptoms came on slowly but now the muscle pain has gotten so bad that the Dr. recomended I cut the dose in half for 4 days and then take half every other day for 4 days to help get off it. I will let you know what happens. The pains have gotten better after just 2 days, but I do have tightness in my chest he said that should get better in a few days F 20 4 years

 1  Asthma and Allergies couldn't sleep!!!!!!!! It helped some of my congestion but I didn't really see much of a difference with the asthma. Never had problems sleeping at night, but on this medicine I did. I took it at night, and I couldn't sleep. Out of the 4 days I took it, I would get 3 or 4 hours of sleep every night. The 4th day I took it, I didn't sleep AT ALL and couldn't fall asleep during the day. I didn't take it the next night, and slept perfectly. I didn't wake up once during the night. Never taking it again F 20 4 days

 1  asthma For eight months, I experienced debilitating knee pain. I needed crutches for five months. I fainted a few weeks ago and I discovered that symptoms like my horrible knee pain were similar to those in other sufferers of Singulair. I've been off of Singulair for about two weeks now and I have almost no pain in my knees now. Side effects = severe knee pain, muscle pain, muscle weakness, swollen joints, difficulty breathing, fainting F 20 3 years

 1  Asthma/Allergies/Chronic Sinusitis When I was about 13 my doctor put me on this medication to help with severe asthma and allergies. I was an extremely happy, intelligent and outgoing child before I was put on this medication, but once I began taking it, it was like I was a different person. I was suddenly extremely irritable, prone to aggressive outbursts, chronically depressed, developed severe insomnia, developed a severe anxiety disorder accompanied by massive and frequent (3-6 times per day) panic attacks, began to fall asleep and hallucinate during daily activities, catatonic episodes, experienced horrible nightmares and perhaps most annoying of all, I experienced uncontrollable and unceasing tremors and 'ticks'. After 1 year on Singulair I attempted to commit suicide, 6 months later I attempted again, and again 2 years later. When I was 18 my doctor took me off of Singulair because my asthma had seemed to improve, one year later she put me back on it because of chronic ear infections. That one year that I was off I have taken myself off of singulair again, after happening to review a patient information handout at work one day (I am a pharmacy technician). I have been off of it for a week now and already I am beginning to see beauty in the world again and feeling more confident in myself. I feel as if being on singulair has ruined my life. My whole adolescence was consumed by this drug, and I was coming close to trying to kill myself again, before I took myself off of it. This drug has taken away time and ruined relationships that I will never get back. I am writing this note on here in hopes that patients and parents consider very carefully the side effects of this medication and the implications that it carries with them. Yes, it got me off of my inhaler, but I paid a heavy price for that convenience. F 20 6 years
