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  Mild asthma, post-nasal drip Rage, anger, dizziness, anxiety, depression, migraines, muscle weakness, unexplained bruises, confusion, feeling too hot, feeling too cold, more infections, ear pain, sinus pain, flu-like symptoms My doctor convinced me when I first started taking Singular that it could not possibly be the medication causing me to have a variety of side effects like anger, rage, dizziness, muscle weakness, etc. Over time the side effects got worse. I went to a Psychiatrist 6 months after starting Singular and got prescribed an SSRI to help with anxiety. This helped for a while. After taking Singulair for 4 years, it suddenly got worse. I was convinced there were voices inside my head telling me to move (I moved across the country), but side effects didn't stop until I stopped the medication. It's been 4 days since I stopped Singulair, and still don't feel normal. So please, if you're considering this medication please be careful and let someone know that this medication can have certain effects on your mental well being. In my opinion, Singulair/Montelukast should be taken off the market for most situations. M 33 4 years

 1  Allergies Depression, Anxiety, Suicidal thoughts, aggression, nightmares I knew the side effects even before I started taking this, and I'm glad I knew because I would have stayed taking this medicine and it would've been torture. I quickly began to feel sad and it was a constant feeling. I couldn't even be around family or friends because I would just begin to cry. I also have been fighting more recently with my boyfriend. The first 3 days I took this medicine I have had the worst nightmares of my life. Keep in mind that I have never suffered from any mental illnesses, but this pill really changed the way I viewed my life and I will never be taking this again. F 18 5 days

 1  Severe allergies Tremors, fatigue, brain fog, depression, anxiety, HAIR LOSS, auditory hallucinations, sleep disturbances, weird dreams, irritability/aggression, no sex drive I started taking Singulair in conjunction with Allegra due to severe allergies. The first 2 weeks I started taking it, it was great. Took away my nighttime nasal stuffiness, made me sleepy enough to actually fall and stay asleep. My only complaint then was no matter how much I slept at night I always woke up so incredibly fatigued the next day. Over the remaining 2 weeks I have developed all the other symptoms I mentioned above. My anxiety was getting so bad it would wake me up in the middle of the night mid panic attack. I started to hear songs in my head on repeat, some that I had heard recently, some I hadn't heard in years. And no matter what I tried I couldn't get the auditory hallucinations to stop. I became increasingly agitated and irritated, to the point I was kind of afraid to be around my family because I was afraid I would snap on them for no reason. Completely unexplainable stomach pain. Went to my family doctor because I was convinced I had either a UTI or an appendicitis. She ruled out both and said the singular would not cause symptoms like that. Went to my OBGYN and got an ultrasound because I thought I may have had an ovarian cyst, nope. Completely unexplainable stomach pain that bothered me almost 24/7. And right at the month mark of taking this medication my hair started falling out in handfuls and I was afraid to take showers. DO NOT TAKE THIS MEDICATION. F 30 1 months

 1  Asthma Depression DO NOT TAKE! ITS NOT WORTH WRECKING YOUR MENTAL HEALTH JUST TO BREATH. For 2 years and 9 months I was fine, but in August of last year I noticed I was depressed feeling (totally unlike me!) Didn't really link it to anything other the pandemic. Nope. Continued to get more depressed. Planning on discussing with my pulmonologist on safely discontinuing this drug! F 28 3 years

 1  Severe allergies Singulair (an allergy medicine) caused me to have suicidal thoughts and I put a fork to my throat this morning over something stupid and my mom talked me out of it. I'm not the suicidal type and Singulair almost made me take my life. I also have had aggression, worse depression, rage, and not giving a rats booty on what I say to anyone. I talked to my mom like she was a dog and I'm not that kinda person. I even cussed my own husband out a couple times. I would NEVER talk to anyone like that! I was literally scared of myself. I even broke something of my great great grandmothers and it was one of the last objects my mom had of hers. I'm not the violent type at all. I'm hoping within a few days I can start feeling better. This medicine needs to be taken off the market. F 28 40 days

 1  allergies/asthma severe stomach pain, vomitting, diarrhea, headache, dizziness, mental confusion, brain fog, memory issues, word retrieval issues, depression, lack of empathy, no desires(sexual and physical touch), isolation, fatigued, no sleep, nightmares, and hopelessness. Do not take this medicine!!!! It changes your quality of life and you don't even know why or how it happened. I found out when I was checking singulair's interaction with supplements I was going to take to help with my brain issues and found this site and saw the same symptoms happened to other people. I have since stopped this med and in 2 days my brain issues started improving in addition I'm happy again....... F 52 8 months

 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.

 1  Eosinophilic esophagitis Shortness of breath and depression. I stopped taking it nearly two weeks ago and have experienced mouth sores and burning lips. I've applied everything from chapstick to Vaseline to coconut oil and the pain only stops when they're slathered in one of the above so I've been applying these things every 5 to 10 minutes to stop the pain. I wonder if anyone else has experienced something similar. It did help with my asthma but was not worth the side effects. F 60 2 months

 1  Asthma First time taking these, straight away my teeth hurt. I had mood swings and my sex drive died almost over night. They do help asthma there is no denying that but the trade off is awful. Hair loss, depression anxiety all of which I have never really suffered from. Being very in tune with my hormones I could sense I was not myself almost instantly. Symptoms did appear to subside. I missed a week or so and my asthma began to worsen again. Once I started again my mind went out the window and rage almost entirely consumed me, not to mention coming out in a severe rash in the space of a couple of days. Would not recommend would rather suffer asthma. M 29 4 months

 1  8 months Singulair 10 mg tablet is scary, the drug was helping my breathing while I was continuing using it but I wasn’t ok at all which I did not notice about the reason of side effects, and I just figured out that around 15 days since last dosage after 8 months of using 10 mg, I had hard breathing, headache, Feeling nausea, insomnia, sleepless, little shaking left hand, diarrhea , and a rapid of fast heartbeat but the big problem was my the mental issue, so mood changed negatively and has depression and anxiety. However, after the hard time visiting many doctors to find the problems, I found that after reading people experiences over multiple websites it’s the singulair plus it returned me back to past around 5-6 months ago when I was stopped taking singulair for one week, I remembered I been to emergency had headache, insomnia, chest problem till I took it again once a day before sleeping which made me not ok. I am not Recovered a 100% and still having hard times but for sure I will be ok very soon. Not recommended at all it’s not worth it plus asking qualified dr is important. Stopping and using can cause series side effects. I’m better but I believe withdrawal will take time since I am daily improved from the day I quit turkey. M 30 1 days

 1  Allergies and Asthma Gastrointestinal distress daily. Upper respiratory and sinus congestion and mucus. Disturbed sleep patterns with frightening vivid dreams. Mood changes including anxiety and depression. Severe neuropsychiatric adverse reaction - paranoia and severe and chronic auditory hallucinations. Stopped med one year ago and withdrawal period was very difficult. No doctors were of assistance in diagnosing connection to Montelukast. Most side effects decreased or completely resolved within several months of stopping the medication. There is a withdrawal period. Do not stop and start this med! We tapered off slowly. Dangerous medication for adults and children. M 30 20 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

 2  Asthma Mood swings, depression, couldn't motivate myself to get out bed, couldn't concentrate, and being in a slow fog with no care. The leg cramps got worse in right leg's knee and hip keeping me from sleeping and pain killers didn't seem to help. Aftestop taking realized it was beneficial to my asthma, but in my opinion not worth the cost. Immediate mental improvement after stopping, but the leg pain is still there. I'm hoping for it to eventually to fade. Doctor, nor pharmacist, ever discussed any side effects. If they had I would've reported the symptoms way before they interfered with my life. F 46 60 days

 1  Asthma & allergies Depression, anxiety, suicidal thoughts, weight gain, loss of interest in everything, no libido - just not myself and so far off from normal me. I didn’t notice significant improvement in my allergies and asthma. I have felt something off in taking this drug and I now realize that it has caused a lot of very serious side effects. I’m seeing very small improvements but have only been off a short time. Very scary. 42 10 months
