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  Seasonal Asthma It helped my seasonal asthma. However, the longest stint that I have ever taken monteleukast was about 2 weeks at a time in the past. This year, I decided to keep taking it after allergy season. Very bad idea, I experienced pressure headaches behind my eyes, loss of interest, fatigue, anxiety episodes, feeling of light headiness and wake up in the middle of the night with my heart racing and wouldn't be able to go back to sleep. My feet also started sweating quite a bit. Today is the day that I stopped taking the medicine and so glad that I found the solution to this problem. I have never normally been this anxious of a person and cannot wait to return to my normal self M 22 3 months

 5  Asthma none I have been a severe asthmatic for my entire life. I was diagnosed at 6 weeks of age. I struggled for my entire life to get my asthma under control. It is only now (and after almost seven years of using these meds) that I have been able to participate in regular activities that for so long I was unable to do. I love this drug!!! F 23 6.5 years

 5  asthma and allergies I have gained 15 pds and seem to be alot more irratible than before. I am also a little concerned about the effects of breastfeeding though. I have a 4 mth old and I know she sleeps more during the day when I take singulair. However, my asthma & allergies have gone away almost entirely and I have yet to experience any serious side effects. Its great to be able to breath u know even with the weight. I will contunue to monitor and research though. Unfortunately insurance becomes more expensive everyday and I have to guit the medication due to the expense!>] F 23 1 years

 5  allergies None OMG, I can not believe all the bad things I'm hearing about Singulair. I have been on this medication for two years for allergy season and it works wonderfully. When I got sick it took me a while to go to the doctor, which made my allergies even worse, but within the first week I started taking it I notice the difference. I breath better, I don't have any allergy symptoms and I sleep well at night. My bf has asthma and it works for him also. Are you sure you guys are not exaggerating? I work at a pediatrician office and most of our asthma and allergy patients are on Singulair and I have not heard any complains. The patient's parents like this medicine. I know that every medication works different for everyone. Some medications work good for some people and for others they have nasty side effects but are you guys sure that yall don't have something else going on in your lifes that is making you guys depressed and act crazy!?.

 5  Asthma Mood swings, serious emotional side effects Singulair has really bad emotion side effects but it has saved my life. I started taking it when it first came on the market for asthma. Before this drug I was very sick and never slept one night without an attack. 12 years later and I sleep, every night. I only wish it was less expensive( 230ish a month without insurance...ouch).

 4  indoor allergies AND asthma audio/visual hallucinations I had been taking Singulair to great effect for a few years when, quite suddenly, I began to get the most bizarre audio and visual hallucinations. As I began to fall asleep, I could hear people scream and yelling things at me, sometimes just random snippets from conversations that were completely in my head (I lived by myself.) After these began to occur more frequently, the hallucinations got worse, and I began to see strange things when I so much as blinked. I thought it was due to a particularly bad sinus/upper respiratory infection, and tried to not worry about it until I was looking over the patient information sheet and noticed, for the first time, the instruction to patients that should they have the extremely rare, but serious, side effect of hallucinations, to call their doctor immediately. I was away from my doctor at home, but called him anyway, and he literally had me switch drugs that very same afternoon. Scary stuff. F 23 2.5 years

 4  Chronic sinisitis None. I have been taking this drug for 2 weeks and I have not noticed one thing yet. I have had sinus infections forever and constanly stuffy. I hada infection and went on this instead and I honestly can't say anything bad about it yet. I have been reading through all of these comments and I find it hard to believe it has such large side effects for some people. however, Everyone reacts differently!! F 23 12 days

 4  Asthma/Allergies None when on the medicine. If I take a break for even a day or two it affects my mood. I get highly aggressive, cry for no reason, and even have what I would call severe depression. It works great and helps, but I skipped a few days on purpose this last week to see if it still caused the same reaction. After two days I was scaring myself with my thoughts so I went back on it. I also take a lot of other allergy/asthma meds and this was the only variation in my routine. I have not ever have thoughts or feelings like that before, besides when I have missed doses of Singulair. I tried talking to one of my doctors about it but they just advised me not to miss a dose. Be careful when starting because if you have the same side effects you may not ever get to stop. M 23 3 years

 2  Allergies Crazy dreams, urinary urgency, nausea, depressed and very irritable This drug scared me into thinking I was pregnant! I had all the damn symptoms of pregnancy and I took a test and it was negative. Then I looked up the symptoms others have had from Singulair and I realized why I had been feeling so strange. It helped my asthma but it's not worth feeling like I'm going out of my mind. I'll stick with Zyrtec and Benadryl at night. F 23 7 days

 2  asthma possible depression, anger I started taking singulair and didn't notice much difference in my breathing, however, I DID notice that if I missed a dose, I went through bronchial HELL and even my Maxair was hardpressed to rescue me. Also, I have been more depressed and incredibly angry/irritable lately. After finding this site, it dawned on me that this could be linked to the Singulair. I took myself off of it a few days ago, and on Saturday, I felt like I had been set free of all of my emotional turmoil. I feel like a new girl. No Singulair for me! F 23 2 months

 1  Allergies & Asthma This is my first night taking this medicine. I tried to sleep and had very vivid thoughts and dreams. I've been up every 5 minutes literally because when I fall asleep I feel like I can't breathe and gasp for air. It's really very scary. I hope this leaves my system soon. I just want to go to sleep. It's safe to say that I will no longer be taking this medicine. F 23 1 days

 1  Bronchitis/Temporary Asthma Caused tremendous anxiety. I had frequent panic attacks that went on for hours. Also caused severe depression. I did not notice any difference in my ability to breath, if anything, due to the anxiety my breathing was worse. Bad show. Works for some people, but definitely not for me... M 23 3 days
