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  for asthma and allergies I was prescribed singulair about two years ago to help control my asthma. After a few weeks, I noticed I was not feeling like myself. I was increasingly anxious and angry. I just felt down and negative about my life. I distinctly remember the day I figured out it was the singulair causing my mood issues. I was standing in my kitchen thinking about what to make for lunch when I became so angry I was physically shaking because I realized that my husband had eaten the last of the leftovers. I knew this was not a normal reaction, and I've never had anxiety or anger issues before or since. I stopped taking the medication and told my doctor, who shrugged it off and said there was no evidence that this drug caused my anxiety. I can't believe they prescribe this stuff to children :( Take it off the market!!!! F 30 3 months

 1  asthma hyperactivity, aggressiveness, irritability, anxiety, agression Ever since my 4yo was put on Singulair 4 months ago he was a terror. Took him off, in period of 2 weeks things slowly started getting back to normal. The terrible side effects he experienced were not worth taking the medication. I would not reccommend Singulair to anyone. F 30 4 months

 1  Allergies Not sleeping, complaining about legs hurting, nasty attitude, hateful, mean, crying, hallucinations (after a day of the medicine) My almost 3 year old daughter was given this for allergies and back to back sinus infections. The medicine did help with the allergies and runny nose, but the side effects were far worse. It was over night my daughter went from a sweet girl to a hateful little girl - I thought I had done something terribly wrong somewhere down the line. Now after reading all these comments I know it was the medicine without a doubt. I had a gut feeling about the medicine she was on, so I stopped - overnight her mood changed - sleeping is still a little issue, but at least her sweet self is back - I have my daughter back!

 1  Seasonal Allergies The side effects that I have read about, are exactly like what my 2 and a half year old daughter has been going through. I put her on it almost 2 weeks ago and noticed a drastic change in my child. She woke up totally freaked out with a nightmare @ 1st...then it progressed. Her behavior has become EXTREME and it's very hard to communicate with her...she acts (seriously) like a mental patient with a crazy look in her eyes half of the time. She will NOT go to sleep in her bed like she used to and has become so upset when we tried to put her in her bed that I thought she were going to pass out or have a seizure....she stopped breathing followed by blood curdling screams. The following day she came up to me and head butted me in the nose...not an accident. I had started to feel like I had lost my once sweet little angel to a horrible mental illness. Then I remembered my Dr. telling me that if I notice any "side effects" to let her know and stop treatment. Side effects....I'm thin Do the research! F 30 2 weeks

 5  Asthma/Allergies Mood swings, depression, suicidal thoughts Both my son and I have been taking SIngulair for a year or more. I have not noticed any negative side effects until recently. I have had a plethora of moments where I can't seem to shake a dark mood. I am prone to these "phases" and have thought nothing of it. I have not been taking this medicine for a few days and already I am noticing a change. I CAN'T BREATHE AT NIGHT! I wake up once or twice and have to rely on my inhaler. I don't want to think that I must live with either bad moods or breathing problems. This medicine has helped me with the later, but I just can't be sure it's the cause of the depression as of late. My son has had zero sinus infections since he has been on this medication and I haven't really noticed a change in his behavior. But thanks to a few posters, I am going to seek an alternative to this medication. F 31 1 years

 5  Allergies None, worked as I expected I felt like I had to leave a review because of all the negativity. Not to dismiss them, but I want people to read this and see that not all experiences are bad. I am a football coach and took it for two years because the allergy issues I had when I only took an antihistamine was unbearable. Singulair relieved probably 85-90% of my allergy issues. I finally got off of Singulair because I decided to do allergy shots instead. Would recommend to anyone with the time and means to get shots. If not, go with Singulair. I had ZERO issues with it.

 4  Asthma and chronic rhinitis Flushed face, nightmares, lactose intolerance, and increased sensitivity to acidic foods. It worked very well in treating my asthma, allergies, and sinus symptoms. Unfortunately I couldn't deal with the digestive issues it caused and discontinued the medication. I never determined if the flushed face and nightmares were directly caused by Singulair.

 3  Asthma I am glad I came across this website. I am generally a happy go lucky person. In the past year or so I have experienced wild mood swings, anger issues and sometimes depression. I am scared to go off because it actually works and helps control my asthma. I am 31 years old and play a sport with need for lots of endurance. I will be speaking to my dr. about other options. Geez... Glad its the meds and I am not this mean person:) M 31 7 years

 3  Allergic rhinitis After 3 days, although my allergy symptoms had completely subsided, I started experiencing nausea around the clock. Then came the anxiety and ocd symptoms. On the 9th day I felt the most terrifying racing heart and palpitations. And on day ten my mind was racing so much I felt like I should be committed. I will never take it again. It DID help reduce my allergy symptoms significantly, along with Flonase and Claritin. F 31 10 days

 2  SINGULAIR This drug was giving to my daughter at the age of 2 if she was having side effects, she wasn't able to explaine them not knowing any different. Been given this drug at the age of two and now five we are no longer giving her singular. Rather this is wrong or right we have taken her off of it as parents. As a mother I have always wonder why this girl can't sleep all night??! When the drug was filled we NEVER had any information of possible side effects now after 3 1/2 year everthing is coming to a head. Side effect of restlessness, tingling (always itching hand and feet) split seconds of mood changes, who would of ever know? This poor little 5 year old has not taken singulir for the past 2 days and we are already seeing improvements in her sleep and being able to sleep soundly! We will be meeting with an Allergy, Asthma specialist next week it will be interesting to see what it is he says and what kind of drugs he will put her on? I know it won't be singulair. This was the drug of choice to keep this little girl under control with her asthna and she have been admited atleast a year to our local hosptial. F 31 3 years

 2  Chronic Bronchitis Depression, cloudy feeling, more irritable, Acid reflux issues, longer menstral periods, anxiety, HORRIBLY DARK thoughts. I thought I was going NUTS! I went to my Dr. because of my symptoms and he thought my hormones must be out of wack. After exams and blood work, everthing came back fine. It NEVER occured to me that this medicine could cause all of my problems. I'm glad to have found this site... maybe I can try to get back a year of my life!!!!! I would rather have bronchitis than continue feeling like this! F 31 1 years

 1  asthma anxiety, panic attacks, depression, almost completely mute, O.C.D. My daughter has been taking Singulair for many years(she is only 11), she has been in theropy for many different problems, and we have had many different things told to us not knowing that Singulair might be to blame, she is on an anti-anxiety and an anti-depressant, she was also on other meds. for panic attacks. She has also been almost mute except at home, for years. I just found out about this and I am feeling very guilty about giving her something I thought was helping her asthma and may have robbed her of years of her life.I certainly hope someone starts a lawsuit against this company.

 1  asthma/allergies I took this medicine on and off for 4 years. I went back on it about 8 months ago after over 1 year off of it b/c my asthma was bad again. I am naturally a bit anxious so didn't realize until I started doing some experimenting with my medicine. I was having extremely bad/vivid dreams, more persistant and intense anxiety and frequent diarrhea and stomache upset. I take a lot of other drugs for asthma so it was difficult to single this one out. Wow what a difference in my life. I can't believe that none of the 5 doctors I have seen ever mentioned the side effects, clearly they are downplayed too much. IT DOES help my asthma, but is NOT worth it! F 31 4 years

 1  Allergies and Asthma Sleep disturbance, vivid dreams, night terrors, anxiety, depression, auditory hallucinations, hair loss, sinus congestion... Neuropsychiatric/mental health side effects do not simply go away once stopping the medication. Stopping and starting the med is not a good idea and there is a long period of withdrawal issues post Montelukast. M 31 17 years
