For Allergic Rhinitis: “After took for few days, I felt my gum like pain. Anyone experience it? Is it this is the side effect.”

For Asthma: “I have been on Singulair for a couple weeks after years of being on a steroid inhaler for exercise induced asthma. It has been working great but I'm gaining weight like crazy. So unfortunate but I will go back to my inhaler.”

For Allergic Rhinitis: “I have pretty bad anxiety/depression naturally so after reading that montelukast has a black box warning, I honestly was terrified to take it. However, I finally did out of desperation to feel better. I've been on it around 2 weeks now, maybe 3. No side effects. I do notice I'm more hungry than usual, but not sure if that's related to this medication or not. It has helped my allergies tremendously! No increased anxiety, depression etc, no heart palpitations like I get with Claritin, Zyrtec etc. nothing negative to say about this drug! Works for me! You'll never know how it'll affect you personally until you try it. I'm glad I did. Hope this helps.”

For Allergic Rhinitis: “My Dr. gave me montelukast for Allergies, it makes me sleepy so I take it at night and I can breathe better, but the side effects are leg cramps, every muscle hurts, feels like I just want to collapse and cry, can't seem to wake up and get out of bed, depression, anxiety, angry, irritated easily, bloated and gassy. I told my Dr. that I stopped taking it and it effects my mood and she said that's must be what's wrong with my son he's on it too. I stopped taking it and just going to do Claritin or Flonase.”

For Allergic Rhinitis: “My doctor gave me montelukast for allergies and have been on it for about a year. I recently stopped taking it cause I've notice I'm getting leg cramps at night in bed, my entire body just hurts. My anxiety is through the roof and my mood has been bad - everything and everyone irritates me. It makes me breathless when walking and cough a lot more. Didn't take one last night and I feel more relaxed today.”

For Allergic Rhinitis: “I've been taking allergy pills of one kind or another for 30 years, I call these my breather pills. I don't use them all the time, but when my other pills don't work I take these and they work wonderfully. I've noticed it's harder to get back to sleep after a potty break during the night, but otherwise nothing worse. A real life saver for me.”

For Allergic Rhinitis: “I have been taking the generic of singular for probably 4-5 years. I was having horrible sinus infections and stuffy feeling in my head continually. It completely relieved me of this problem. I have had some anxiety occasionally however I’ll take the trade off.”

A · Taken for 1 to 6 months August 19, 2020

For Allergic Rhinitis: “My allergies have caused me to be miserable for my entire life, ruining vacations and causing me to miss school. I have allergy and exercised induced asthma, disallowing me from doing things I love like hiking. My allergy symptoms have completely disappeared, and I am able to run and play without stopping every minute or so to catch my breath. One thing that has happened is that I am much more irritable, provokable, and angry. It has been hard to sleep as help. These are things to be aware of, but I personally will be looking for ways to solve these new issues because Singulair has given me a new life.”

Singulair (montelukast) for Allergic Rhinitis: “Medication works well but has some crazy bad side effects’ First time I took it my allergies was from high pollen counts and mold and I was coughing ever second. I was scared but the singulair took the coughing away like right away. A week into the medication I woke up with night terrors so bad, dry heaving, a pending doom feeling. It was awful. Did not take the pill the next day and the side effect went away. Tried this again and it was like you got super sleepy but could not sleep. It was disastrous. I think a regular antihistamine would be better than this rubbish”

Singulair (montelukast) for Allergic Rhinitis: “I was so happy taking this Singulair medication because it actually worked however I did have some stomach pains and some diarrhea but wow my allergies were gone! I did get a lil depressed on it but honestly it was worth it with my allergies gone!”

Singulair (montelukast) for Asthma, Maintenance: “I stopped taking Montelukast after several years. Learned of an FDA warning re: cognitive effects. My breathing has worsened significantly in recent months. My breathing worsened this spring 2020 post MS exacerbation. My air conditioner was occupied by birds - mgmt. neglect of outside grille to prevent birds, bats, etc. I also use AC for MS. Tested neg. for SARS CoV2 April 2020. Started nebulizer yesterday to complement Advair. I will try Montelukast again. Mood wise I did not notice anything significant. Anxiety per MS is a given-like living on the edge of a cliff. Stupidity reigned in mgmt as they refused to clean the air conditioner for pathogens. They violated Fair Housing Law - acted in accordance with Human Rights. 30th Ann. of ADA 7-26-20!”

For Allergic Rhinitis: “Began taking Montelukast in Feb for allergies. Covid hit and I assumed my anxiety and depression were due to the state of things. Last week I happened to check my blood pressure to find it at 140/90. As the night went on it got worse and I ended up at the ER where it was 227/125 and was being monitored for a heart attack/stroke. I’m a healthy 41 year old woman who doesn’t smoke, eats right, exercises and isn’t overweight. I’ve also been bruising easily on my legs. After another trip to the ER the next night for similar numbers I am now on meds for hypertension twice a day and I believe it’s all due to this drug. I’ve been off montelukast for a week and am hoping I’ll be able to come off the BP meds too once it has left my system. If you take this drug please monitor your blood pressure. It’s not listed as a side effect but have read dozens of cases where people’s BP skyrocketed as a result. The drug did work for my allergies but my heart health is far more important.”

Singulair (montelukast) for Asthma, Maintenance: “I’ve been using this medication for a few days and the anxiety is so bad. I think I’m going off of it. It was so expensive to buy but I can’t handle the way it makes me feel.”

For Allergic Rhinitis: “Dr recommended Singulair for post nasal drip and a cough. Took it 1 night and have decided to stop since I felt like I couldn’t breath and got a non stop cough! So one of side effects is cough! I’m trying to stop a cough, not make it worse! And all of the other horrific side effects that come with taking this drug, I’ll pass! No thank you! I’ll stick to Flonase which has helped me a lot!”

Daughter June 27, 2020

For Allergic Rhinitis: “My mom was on this medication I was not aware she was I just knew she was on something for her allergies. All the side effects listed that others are reporting on here, are exactly the same ones she had. I wish I would have done research known more about what had been prescribed My mother committed suicide a month and a half ago and we couldn't figure out why. My brother passed away tragically 11 years ago one of the hardest times of our lives and my parents and I made it through that. We were at a point where we didn't dwell on his death as much Things were looking up and our family was doing good I gave my parents 2 grandkids. No problems in my parents marriage. No problems with me. I had actually just sent a Mothers Day present that she never opened. I really hope people read reviews on this medicine and I'm glad others have shared their side effects to help others. I'm glad that my dad and I might have an answer to our many questions. Please do not take this med It should be taken off the market”

For COPD: “I've had COPD for over 10 years and I was taking 1 montelukast 10mg in the evenings and after reading about half life of the drug it seemed to me to be must effective when I was asleep so walking is my exercise induced asthma I started taking my 1 10mg pill in the mornings and it has turned my activity around. I feel much MUCH better breathing in the daytime I can tell my bronchial tubes are open. I have had no night time issues either.”

For Asthma: “My son has been taking montelukast from age 3 to 7 years. He went onto it for viral induced wheeze/asthma. He also has hayfever. Recently age 7 he has been developing skin rashes/bruises on his shins which is a known side effect of this medication. He regularly would complain his legs hurt even before the rashes started. The Doctor has told us to come off the medication. Its day 3 since he is off the meds now. He has also been an anxious child who lacks confidence. I dont know if the anxiety is related to the medication.”

Spettro · Taken for 1 to 6 months May 25, 2020

For Asthma: “I have reactive airway disease and I really get hit hard with the wheezing during allergy season. I can honestly say that this stuff is fantastic and really works. Although it takes about 4-5 days to kick in to clear up my breathing. The only negative is that it gives me the worst constipation imaginable. So unfortunately I have to stop for now. I read another review where the person had constipation with Singulair but resolved it by taking magnesium. So I'm going to give that a try and see what happens.”

For Bronchospasm Prophylaxis: “Singulair was helping my breathing while I was continuing using it but I wasn’t ok at all, and I just figured out that around 15 days since last dosage after 7-8 months of using 10 mg, I had hard breathing, headache, Feeling nausea, insomnia, sleepless, shaking, 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 it, I remembered I been to emergency had several side effects till I took it again once a day before sleeping. I am not Recovered a 100% but for sure I will be ok very soon since I quit turkey taking this pill and I hope everyone is ok. Please ask a qualified doctor before use it and make sure to know the side effects and when to use and stop.”

For Asthma, Maintenance: “I had a severe allergic reaction to montelukast. Skin rash, difficulty breathing, high blood pressure, hot flash, legs tingly. Weird dreams, cough worse. Quit taking after 2 days. Feel terrible on it.”

Gato · Taken for less than 1 month May 4, 2020

For Allergic Rhinitis: “I can't believe that montelukast was the reason I was feeling so depressed, anxious even my legs so shaky, I didn't understand why I was so moody and trying to isolate myself from my family. After reading the reviews for this medication I realized I wasn't alone , I'm going to stop this medication today. Please stop taking this medication if you start developing Anxiety or depression and ask your doctor for something else. Good luck everybody!”

Singulair (montelukast) for Allergic Rhinitis: “I was given this medication Singulair for chronic nasal congestion and Rhinitis. After about 2 months, I started to notice my mood changing. I was more argumentative almost to the point of aggression. When I started to have bizarre dreams I then researched the side effects of this drug. Here is what was listed: mental/mood changes (such as agitation, aggression, anxiety, trouble sleeping, abnormal dreams, sleep-walking, memory/attention problems, depression, hallucinations, thoughts of harming yourself/suicide). I immediately stopped taking this medication (it wasn't helping that much anyway) and these side effects have stopped completely. PLEASE be mindful of ALL the side effects of any medications you are taking! I never would have believed that something to help with nasal congestion could cause such problems.”
