Montelukast for Allergic Rhinitis "I felt the need to write this review for anyone who is scared due to possible side effects. I was in here about a week ago reading through all the reviews just absolutely terrified. I told my husband I wasn't going to take it. I suffer from horrible sinusitis, and I've tried everything. My husband talked me down, and he said we would monitor my behavior closely. First night I took it before bed. I had every expectation to wake up in some kind of horrible headspace. I woke up after a good night's sleep and didn't feel any different. My symptoms were about the same as well. I have consistently taken it for 7 days now and my sense of smell is coming back a little. I don't notice ANY side effects. I feel myself. If anything, I feel happier because I can kind of smell again! It has only been a week, but it has given me hope. So if you are here trying to read reviews to make yourself feel better. Listen. I was completely psyched out about this too, but I am so glad I decided to take it."

Montelukast for Asthma "Be careful! After years of being misdiagnosed, I was given Singulair. Within 4 weeks, I no longer needed my nebulizer or rescue inhalers. I gradually became more tired and extremely agitated. I began hearing voices in my own home, and I live alone. It got worse, not better. One night, I was convinced someone was in my home. Every light in the house was on. I still kept seeing someone! Coming from a military background and secure in owning firearms, I was searching my home with a gun. I was looking for an intruder who was NOT there! That was my final straw. I threw my Singulair in the garbage. I’m still agitated and frustrated. I am going to try over-the-counter medication deemed safe. I’m not sure how long the agitation and tiredness will last. I pray this will help someone. Please be careful on this medicine. For me, it’s not worth it. In 55 years, I’ve never seen anyone or heard voices in my home until Singulair. (5 weeks total taking it)"

Montelukast for Allergic Rhinitis "My doctor prescribed me Singulair after my allergy test results came back. Went straight to reviews and seeing so many bad reviews, I got worried. I have a history of anxiety and panic attacks, and people were stating it's only getting worse when you take Singulair. I even rang my doctor, saying I'm really afraid to take them, but he politely asked me to give them a go. Not only did my allergies settle down and symptoms were really bad, I must say. I got back my sense of smell, I could breathe through my nose again, my sleeping patterns improved a lot (some people experienced nightmares after taking Singulair, in my case I finally could sleep through the night, having the nicest dreams ever). Anxiety and panic attacks went away. In my case, it did wonders."

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."

Montelukast for Asthma "My asthma came back strong at about age 46. I tried everything. I couldn't exist without an inhaler nearby. Couldn't sleep at night for more than 2 or 3 hours at a time. Woke up constantly always coughing. Additionally, I always had sinus infections. This drug has been a life-changer for me. It is a miracle. I haven't experienced any noticeable negative side effects. The first couple of days, I had some dizzy spells, but they subsided. I can't say enough good things about how this has helped me. I went to a couple of pulmonologists, several emergency rooms, and urgent cares, along with my primary. No one ever recommended this. Finally, I found a RA or PA, I don't know, but she prescribed this for me and I am forever grateful."

Montelukast for Asthma "While on this medication, my asthma and allergies were almost non-existent. However, I also developed severe depression that almost took my life, anxiety, became easily agitated, and had pain in my mouth and back. Since I stopped, I feel happier, more patient, less sore, but my allergies have come back. If it weren't for the side effects, I would have kept taking it."

For Asthma "Great for asthma and allergies. BUT do not take this if you're trying to lose weight. It does something to you and makes it completely impossible to lose any weight no matter what you do. Fasting 20 hours a day...OMAD, 800kcals a day, 1200kcals a day, eating to TDEE recommendations, keto, low carb, literal starvation...tried it all and nothing worked over the period of a couple of years. Only when I researched 'singulair weight loss' did I find other people with the same issue. Came off Singulair and the weight flew off. Made me feel like I was losing my mind."

Montelukast for Allergic Rhinitis "I have been taking this medication for a few years to treat allergies. At first, I would get headaches, but they went away after a few months of use. I do not have anxiety issues with the use of this drug. This drug is a lifesaver for my allergy symptoms, and I will continue to use this drug."

Montelukast for Allergic Rhinitis "I have had allergies and severe chronic nasal congestion on and off for over a decade now. To the point that all over-the-counter meds don't work. Even paired with a nasal spray, I got no relief. About a week ago, what my doctor suggested was to continue using Claritin-D, along with Flonase, and prescribed Singulair as a supplement. For the first time in a very, very long time, I slept through the night without waking up gasping because I couldn't breathe due to the congestion and pressure. Also, I am able to work without disturbing my coworkers due to the constant nose blowing, sneezing, and coughing."

For Asthma "I tried this drug a few times at the recommended 10 mg and had panic attacks. My pharmacist recommended that I try the children's dose of 5mg and it's been a game-changer! I've had respiratory issues my whole life - dry cough, occasional bronchitis, wheezing, allergic rhinitis, etc. This clears up about 90% of my issues. If you're having psychiatric side effects from it, but you really need it to function, try halving your dose before you give it up entirely."

Montelukast for Allergic Rhinitis "I am a retired physician. Every winter and spring, I suffer from horrible congestive episodes. Once, I became so dizzy that I could barely get out of bed just to go to the bathroom. I saw an ENT doctor who diagnosed me with vasomotor rhinitis and stopped my Claritin. When spring came around, I was miserable again. I saw an allergist who did multiple skin tests and concluded that I had no allergies, urban irritants caused nasal mucosal swelling resulting in my congestion. When my symptoms worsened, I was sent for a CT scan of my sinuses and was found to have chronic sinusitis. Every year, I still have seasonal recurrences of sinusitis. My new PCP decided to try Singulair (Montelukast) along with antibiotics, and now I can breathe out of both nostrils. Yay!"

Montelukast for Asthma "1.5 months on Singulair and so far very happy. I have not had asthma flare-up since beginning Singulair. This is a big deal for me after 1 year of regular flare-ups. I rarely need to use my Ventolin, still on Breo daily. I can breathe through my nose which is very new for me :) The earlier reviews scared me, but so far no issues with anxiety. I did have some weird dreams at first, but that has lessened. I'm very glad for the progress so far."

For Asthma "My daughter had her life ruined by this drug! Had I known I wouldn’t have given it to her! It was good for the asthma at night at first. Then she started having nightmares, odd behavior, aggressive & hyper. The asthma nurse said it was a phase & put the dose up. The next day she was suffering with awful headaches and started to hallucinate...wouldn’t go out in public & ran into oncoming traffic because her brain told her to. Had panic attacks, admitted to hospital for the headaches. I mentioned the drug, they ignored it, took her to doctor who prescribed it to her and he said the drug had crossed the brain barrier causing inflammation and prescribed antibiotics...discontinued it...improvement but my girl will never be the same again...she’s now diagnosed with severe anxiety, OCD & SPD...under CAMHS, mental health, had school counseling...and still to this day no help with withdrawal didn’t go into any detail, no doctor, nurse, or pharmacy will acknowledge that this drug has done this to my girl."

Montelukast for Asthma "After I got asthma three months ago, I personally thought it was going to be the end of me. My breathing was difficult and was making me depressed. I started Singulair 2 months ago. It took about 6 weeks for the medicine to fully work for me, but now I feel wonderful. I feel 95 percent like before I got ill. No side effects for me. I totally recommend!"

Montelukast for Allergic Rhinitis "Singulair worked great for my non-allergic rhinitis and sinus. I stopped sneezing completely for 2 months on Singulair. I was able to breathe so much better, congestion relief. Only issue was I had severe anxiety and occasional panic attacks, even after cutting the pill in half, took every other day. I was truly discouraged because the med worked. I tried my best to continue the med, but anxiety became overwhelming."

Montelukast for Allergic Rhinitis "This medicine changed my life. After 18 months of constant post-nasal drip, coughing up sputum, sore throat, and nasal congestion, I think I may have finally found my answer. I have taken almost every medicine suggested to me and seen over 30 doctors. I was finally put on this for Rhinitis and Asthma, and I started to notice a big difference by 4 days in. It has now been a week without coughing up sputum (something that I had daily for 18 months), and my congestion and breathing are significantly better. For some reason, antihistamines and inhalers don't seem to help me, but Singulair does. I'm so glad that I tried this medication!"

For Asthma "Went on montelukast for mild asthma. It did seem to help me breathe easier, certainly less wheezing. Experienced very intense, vivid dreams - definitely attribute those to this medication because I guess it crosses the blood-brain barrier. Mood was about the same. The reason I stopped taking this was I noticed a weight change (increase) that began around the same time I started the medication. I stopped gaining weight and began losing the 15 lbs I packed on almost immediately after stopping this medication."

Montelukast for Allergic Rhinitis "I am a lifetime allergy injection patient. I have been getting allergy injections for the past 35 years. I have had symptoms of post-nasal drip and clearing of the throat for as long as I can remember that the shots just won't clear up. I started Singulair 10 days ago and my years of post-nasal drip are gone. Yes!!! Gone for the first time for as long as I can remember."

Montelukast for Asthma "I started with Singulair a few months ago. Before taking it, I would be awakened with wheezing, nasal congestion, and just feeling like I could not get enough air. It has been a wonder drug, immediately all the asthma symptoms at night were relieved and stopped the early morning coughing. I occasionally have short-term wheezing, but nothing like previously, and so far no side effects."

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. 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 whatsoever. 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!"

Montelukast for Allergic Rhinitis "I wish I had reported this to the FDA when it happened. I don't know how helpful my account of the side effects from many years ago would be now. However, I would like to share this somewhere, as what I experienced is not verified as a side effect but possibly suspected-I don't want anyone to go through what I went through and not suspect this medication to be the culprit. After taking one dose of Singulair in the evening, the next day, I experienced suicidal thoughts, severe anxiety, and a feeling as if I were being separated from my body (if that makes sense). I have no history of such problems, never took Singulair again, and never experienced what I described again."

For Asthma "Yes, the anxiety and depression are absolute side effects of montelukast. The weight gain and the anger too. I think if you are a younger person at all or a woman who already gets mood swings or related side effects from birth control, stay away from montelukast!"

Montelukast for Allergic Rhinitis "I only used this drug one time, and I took it to help with allergies. I took a 10 mg tablet of montelukast at around 10 p.m. At 3:30am, I woke up and had a panic attack. The whole next day I was trying to fight off panic attacks until around 8:30pm when the drug started to die down. I never took another. The panic attacks have stopped."

Montelukast for Allergic Rhinitis "I'm 49 and have suffered from allergic symptoms ever since I was a kid. Unquestionably, it has reduced the quality of life. Antihistamines were basically ineffective, although I could significantly reduce my symptoms by a strict diet that was developed over the last 30 years through observation (try eating foods high in antioxidants). I do feel much better since taking Singulair, my nasal congestion is much better, and I feel no side effects. My only regret is not trying it earlier."

Montelukast for Asthma, Maintenance "Have been on Singulair since it came on the market in Aust years ago. I call it my magic pill with no obvious side effects despite having many other allergies. I didn't find it helped my hay fever though, so I take half an antihistamine as well in summer when humid and winter when smoke from fires around. I went from high dose cortisone puffers and using Ventolin most of the day, still being breathless and wheezing all the time, to breathing free within 4 days of starting and off all puffers within the week. Due to cost, about a year in was running out, so cut down to half tablet which still left me free of the asthma. Then tried a quarter and found this still worked, so have continued on this since then. (to be continued as not enough space)"
