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  severe asthma mood change, depression, loss of sexual appetite Works great on my asthma-- but really messes with my mood. I thought it was just me... It is not. They need to retest this drug for side effects. F 24 6 months

 1  Asthma Unusually long bleed times - so much that my Hemorrhoids would cause embarrassing stains. General feeling of being emotionally flat... cloudy, muscles easily fatigued. Bleeding that easily can't be healthy. The side effects I experienced are NOT fictitious or confused with some other pre existing ailment. I definitely can not take this drug. I'm jealous of the people who can take singulair. I know dealing with asthma would be much easier if I could tolerate the side effects. If my asthma was absolutely life threatening, I'm still not sure if I would take it. To each their own. M 24 4 days

 1  allergies mood swings, aggitation, weird dreams, extreme drowsiness, chest tightness, emotional breakdowns I already am a bit of an emotional person, but when i was on this it felt intensified x10. I was SO tired i literally could barely drive. I went from eating healthy and working out 3x/wk to just shoving food in my mouth 24/7 and laying on my couch at ALL times possible! very STRANGE dreams, unable to wake up in the morning, felt like i was drugged. allergies were better but experienced chest tightness instead. very easily aggitated and would just completely flip out on people when i normally wouldnt. did not want to be around anyone. stayed secluded and would not conversate with anyone. im a very outgoing talkative run-around type and people seemed shocked when they saw how quiet i was.. had atleast 6 friends ask me whats been wrong with me..

 1  Shortness of Breath Memory Loss, lack of concentation I was prescribed this drug at a trip the ER for shortness of breath. I think I got the catch all "athma & allergy" diagnosis. I don't think my shortness of breath was related to this, so I can't speak for how the drug works. In the short time I was on it however, I did experience memory loss & lack of concentation. I would be getting ready to say something & it would just completely slip my mind. Or I would try to remember something I was supposed to do and I just couldn't. I felt like I was losing my mind. I wouldn't recommend this. F 24 8 days

 1  Son taking it Worsened depression horrible anxiety doesn't want to leave house. Made his sleep issues worsen. In the last year he gained a lot of weight while having insomnia which turned into an eating disorder. He was always so thin. This is the worst medication for anyone in hides the real problems of what is making him have allergies , sinus infections and asthma. It has helped his sinus infection. But he still needs inhaler. I am trying to convince him of the true facts of this medication and what it is doing to his life and state of mind. Now I'm afraid the side effects regarding his heart when he goes off of it. Please discontinue use of this medication. Please have a site on how to discontinue use of this medication without side effects. M 24 3

 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  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).

 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 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

 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

 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  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

 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
