For Allergic Rhinitis: "Do not take this. Research this drug before giving it to your child. It has been known to cause neuropsychiatric episodes when taking it. It is a very dangerous drug and I would NOT recommend this to anyone, at any age."

Singulair (montelukast) for Asthma: "Caused severe anger and self control issues in my son."

For Asthma: "My daughter has taken this for about 8 years. She's always seemed to have extreme emotional reactions to the smallest things. I asked her doctor multiple times if it might be the montelukast she takes causing this. Dr. said "no, reported side effects just happen when the child starts taking it. Must just be her personality". I know what is normal and her reactions were extreme. Everything came to a head this past winter when she started having obsessions about eternity. We took her off the montelukast. About 2 weeks later she had a psychotic break. She was crying all day saying she didn't want to exist. It has taken 2 months to get her back to semi-normal. This drug is not good for children!!! Her experience is not unusual!"

For Allergic Rhinitis: "This was prescribed to my 5 year old for his allergies. It worked wonderfully (2 weeks) until this week. He started complaining of leg and stomach pains, then the diarrhea. We are on day 3 of the diarrhea and he just can't handle anymore. At first I thought it was just bad luck until a little research and reading these post. He will be stopping the medication."

For Asthma: "I'm a 34 year old who has had asthma for years. Over the past 12 mths my asthma has become increasingly difficult to manage, and was severely impacting my sleep and my day to day life. As a result doctor has been trying some new medication. After just a couple days on 10mg of this medication my asthma had significantly improved. Then the side effects started. I lost hearing in my ear and had loud ringing in my ear. I was sleeping non stop, couldn't concentrate or retain information and was suffering from terrible anxiety which I have never experienced in my life. I felt like all I wanted to do was sleep and never wake up. I have never felt so awful in my life. I stopped the medication that night and immediately felt 100% back to normal."

For COPD: "I've had COPD for several years and was prescribed Singular (montelukast) to prevent sleep time exacerbation's. I mean severe too! One night when in the hospital, boom! It hit me and I was even on oxygen. Well, since taking montelukast, even as the generic of Singular (as some may agree, generics often don't have the same effect as brand names), I have had no night time problems."

Singulair (montelukast) for Asthma: "I was started on it after the first acute sudden asthma attack of my life and the inhalers weren't working... which landed me in the emergency room and had some continuing lung spasms in the weeks following this. Once on it, for the first time in many years I was no longer waking up wheezing and with shortness of breath at night. It's been wonderful! Fortunately, I have never had any of the side effects noted by others. I remember feeling early on that singulair may have contributed to weight gain, but it was very hard to tell as I was at that age - late 40s - when this begins to happen naturally. If so, I certainly would have preferred to not to gain weight, but the benefits of having a "normal" life with singulair have been fantastic"

For Allergic Rhinitis: "I had severe allergies and could barely breathe and had to sit up while sleeping since it was so bad trying to breathe while laying on my side while sleeping. I was prescribed this medicine and the doctor told me that I would know within 15 minutes or so whether it was going to work or not. I was totally surprised how fast my allergies went away. My breathing became normal and stopped the sneezing. I researched this medicine after taking it and was surprised about the side effects but so far not a single side effect. I am a totally satisfied customer."

Singulair (montelukast) for Asthma, Maintenance: "I have been taking singulair on and off for years. In the last two years I have had 4 severe asthma attacks and the singulair has not helped. It may have helped my allergic rhinitis. But it does not help my asthma. I will probably stop it."

For Asthma: "Hysterical crying bouts in my 6 year old son on just the second night of taking it. He woke and came to the side of my bed in almost a dazed state, crying and whimpering, when questioned he couldn't even speak! Didn't realize how awful this drug was untilI did the research. It causes childhood depression, nightmares, hallucinations."

For Asthma: "Soooo I started taking singulair montelukast for about a month now. It's been helping my asthma a lot but I've been having horrible depression. I'm very angry most of the time. Everything and anything anyone says will make me irate. I've been having suicidal thoughts. Honestly I rather cough up a lung than be crazy because of this medicine"

For Asthma, Maintenance: "Allergy testing came back negative but when I kept having cold weather induced asthma my doctor wanted me to try this. I'm already on symbicort & was doing good except cold weather. Well, the montelukestat helped it completely. We had a very cold winter this year & I was totally fine outdoors. Also I don't have any of the side effects some people mentioned, I feel great!!!"

Singulair (montelukast) for Asthma: "I read these reviews a year ago and was completely terrified to take this medicine. I let my asthma go so long out of fear that I was going to have a bad reaction that now I need medicine just to breathe at night. I rated it an 8 because I've only taken 1 dose but that was the first night I fell asleep being able to breathe fully in a long time. Today is the first day I only needed my rescue inhaler one time (so far). I'm hoping as I continue to take it, it'll get even better. Also, no side effects what-so-ever. Please try to take medicine for yourself and see how you feel before you put things off. I'm loving Singulair and the way I can breathe!"

For Asthma: "Taking for only a week or so for severe allergies/asthma. I am going to stop taking it and see how I feel because this medicine gives me a funny taste in my mouth and all food and drinks (except chocolate) taste weird to me."

Singulair (montelukast) for Asthma: "Asthma all my life (40 yrs old) but wanted to cut down / get off the steroid inhaler (Symbicourt) as it does lead to weight gain / hunger pangs and bloating of face. Offered Singulair - Took one tablet in the daytime - Wrong thing to do !! Completely sedated feeling. Made a call to continue taking the following treatment : 1. Symbicourt in the morning (Symbicourt users will concede it's like drinking 10 Cups of Coffee) 2. Take a half of Singulair before bed (I have the best nights sleep every night due to its mildly sedative effect). Best of both worlds.. I have never had broken sleep for 40 years.. once I started with Singular I sleep like a baby and wake up completely refreshed."

Singulair (montelukast) for Allergic Rhinitis: "I use to get Singulair thru medicaid/medicare but it's no longer available thru that source. I would have to pay which I can't afford to do. However I am a satisfied x -customer and that is the best medicine I have ever taken for my allergy problem. It eliminated my use of my rescue inhaler daily as in the past. I noticed that I could go a few days or weeks even months without even taking the Singulair most of the time. Singulair helped very well to keep my allergy symptoms away and at bay. I now take a generic brand and it is not the same and I still have to use my rescue inhaler more than I did when I used Singulair. I would recommend Singulair to anyone."

Singulair (montelukast) for Asthma, Maintenance: "I have been on this for several years now and it helps to keep attacks down significantly. I can breathe so much better and it seems to help knock down allergic reaction to many things for me."

For Asthma, Maintenance: "I have been suffering from asthma since the age of 7 and I was recently prescribed montelukast sodium after a bad chest infection which had me hospitalised. I have taken it previously about two years back as well. However since I began taking it this time I noticed I can't fall asleep, I'm badly constipated and extremely lethargic, depressed, irritable and get angered really quick. No medicine is worth feeling this way and I'm stopping this immediately. If a simple drug manifests such tangible changes in your body, imagine what it does to your body silently."

For Asthma: "I have had asthma every since I was born, montelukast helps me breath every day if I don't take it I can't breath but it causes me severe stomach pains, sometimes anxiety, depression, red blotches one my face, I get the sweats and nausea. These are some of the long-term affects I suffer with I would not suggest taking it eternally"

For Asthma: "This medication is poison. I don't recommend. My 5 year old was on this for 3 months when I've notice her behaviour changed, a bubbly happy and active child, had turned into a sad, tearful, tired and unhappy child with every little thing making her angry and depressed. I urge anyone who's taking or is thinking of giving this to their child, as soon as u see the littlest of change stop!! It can really affect you or your child's life. If only I had researched or my child's dr had advised me well instead of brushing my worries under the table, I would have never given this to her."

For Asthma, Maintenance: "Was prescribed for asthma to get me off my inhaler so often. It worked but, I gained 6lbs in 5 days & started having random nose bleeds & waking up with lots of joint pain. Then I stopped sleeping more than 4 hrs a night & I was taking it it before bed. The days were filled with anxiety, brainfog & confusion. Too bad because it really did help control the asthma. I stopped taking it. I'd rather cough than be in constant pain & crazy."

For Asthma, Maintenance: "This medication worked wonders for my asthma! No wheezing and no longer needed my rescue inhaler. After about 2 weeks of taking montelukast my feet and ankles started swelling and my hands and feet started going numb. I eventually had to go to the ER and learned that I had extremely high levels of eosinophils in my blood and was advised to stop taking montelukast immediately. I have been off of montelukast for about a month now, and I am finally getting feeling back in my fingers and toes. If you experience swelling or numbness, get yourself to a doctor and stop taking this medication right away!"

For Asthma: "I was prescribed this for a touch of asthma and bad allergic rhinitis. I took one half (5mgs). The next morning I felt nauseous and dizzy. Later on I developed a low grade fever chills and stomach pain got worse. It was the worse nausea I have had since I used to drink alcohol but without any relief.I do have gastritis in my stomach which could have contributed to my pain. Be careful if you have stomach issues!"

For Asthma, Maintenance: "I decided to try Montelukast(generic of Singulair) after a severe bout of cough/flu aggravated by my asthma; which lasted for well over 8 weeks. Initially I had a very bad headache for at least a week, unabating, and the unusual fatigue and tiredness regardless of what activity I did. The headache dissipated but the lethargy has continued and I never felt like I regained the energy I used to have. So this is very disturbing. I had hoped that after persisting with it for 4-5 months I would feel better but I don't. The tiredness pretty much starts almost immediately after I have taken the tablet in the evening. The other thing which is annoying is the stupid, senseless dreams which I find very hard to wake up from!"

For Allergic Rhinitis: "Although this medication seemed to help my allergy symptoms, my mental health took a terrible turn. For the last few months, I've been having crazy outbursts, going "from 0 to 100" very quickly on an emotional scale. I became super aggressive, could not stop crying, and would lay in the bathtub having suicidal thoughts. I know now that it was this medication, and my doctor told me to STOP taking it. These side effects could ruin someone's life, especially if the people around you don't understand why your behavior has changed. I've also been suffering from severe fatigue--fatigue that is much worse than my normal allergy fatigue. I'd recommend allergy shots instead, even though they are super inconvenient for many people!"
