Singulair (montelukast) for Asthma "On this medication I could finally sleep at night, literally. It helped so much with my asthma and my allergies. I could take deep breaths again. I needed my inhaler much less. But unfortunately like many others.. after three months of taking this (it takes time to build up in your system) I developed severe depression and I was very suicidal. Thankfully, I have a support system that I alerted of this possible side effect, and they were there for me. I went to my doctor and she advised to stop taking it (as I uncontrollably cried in the office) and I felt better within a week of being off it. Don’t let my experience scare you, because I really went back to normal as soon as I got off it. I have yet to find a new medication that makes my asthma/allergy so nonexistent!"

For Asthma "I took Montelukast for my asthma and allergies, and it definitely works to control both of these, but the side effects are bad. As directed by my doctor, I would go on and off of it during the bad times of the year. This caused severe exhaustion for several weeks. The worst side effect, which is not something they mention, is the weight gain and inability to lose weight. I really didn't notice it at first, as I started exercising regularly again at around the same time. Fast forward a year and a half, I am tracking everything I eat and the exercise I am doing-consistently 1000 calories/day deficit. My weight does not budge for four months. I start researching, and something I read mentions medication. Since Montelukast is the only thing I'm on, I look up 'Montelukast and weight loss' and find stories from people who had similar issues. I stopped taking it, and within a month, 10 pounds fell off of me while eating normally. Montelukast definitely works, but beware the side effects."

Singulair (montelukast) for Asthma, Maintenance "I had horrible side effects from Singulair. I started suffering severe anxiety attacks, which my boyfriend (who is an EMT) linked back to Singulair. My allergy doctor wasn't even sure it was the Singulair until I talked to my pharmacist. Heed caution that the rare side effects can happen and that they are scary."

Singulair (montelukast) for Allergic Rhinitis "I have tried Singulair three different times. Each time it has caused suicidal tendencies in me. This happens soon after I take it. My mood was very scary on this. I was prescribed this for asthma and allergies. I stopped taking it since it seemed to just depress me."

For Asthma "This medicine was poison to me. I had it prescribed to me following a mild allergic reaction to a bug bite. I have suffered from mild anxiety in the past, but within a month of taking Singulair, I went from mild to severe. Panic attacks, crying for no reason, racing thoughts, overall feelings of hopelessness. I was at the end of my rope after a particularly bad panic attack when my husband suggested it might be my medication. At first, I didn't believe it, because it was an allergy medicine... how bad could it be? Imagine my surprise when I looked it up and saw there are many, many people suffering the exact same side effects as me! I immediately stopped taking the drug, and now, 48 hours later, I can't even believe how normal I feel. Sure, the allergies are back, but I'll be thankful for every sneeze if it means I don't have to suffer the psychological effects of this drug. I would strongly caution anyone considering taking this medicine (especially if it is for a child) to do your research beforehand and make sure someone you love is monitoring your behavior. For me, it was a terrifying drug, and I am so glad I listened to my husband."

Singulair (montelukast) for Allergic Rhinitis "I have had allergies for 50 years and had reached a point where multiple allergy medicines did not control my outbreaks which were all year long. I tried Singulair 5 mg the generic and thought it was the answer. I slept better at night. I was not sneezing and blowing all day at all and it went well for about six weeks. Then suddenly I began having blurry vision I couldn’t read as well. I had pain in my eye that drops did not help and looked it up and saw that 2% of the people on this have this side effect of ocular complications. In spite of it saying not to stop immediately, I did, and that Improved the vision immediately, but since then I have had aches and pains, and I am sleepy most of the day and I’m sure after reading all the reviews that it’s part of the withdrawal from this medication. I did not have depression or suicidal thoughts thankfully. My daughter has used this medication for a long time with no problem, so just be cautious and watch for new symptoms."

Singulair (montelukast) for Asthma, Maintenance "I have mild asthma that occasionally worsens to be more moderate. I'm another person who has mood effects from taking Singulair, and in addition, it's affecting my ability to enjoy certain flavors. It feels like an antihistamine, sort of, causing my mouth to feel dry, and I feel thirsty a lot. I'd live with that, but I am experiencing this weird agitation that's quite uncomfortable. I'm very aware of it, and I'm an adult, not a kid, so I probably won't bite anybody's head off. However, I think it might not be worth it to me, and I think I'll stop it for a few days to compare how I feel then with what I'm feeling now."

For Asthma, Maintenance "Think LONG and HARD before you take this stuff!! I ended up in the psych hospital on suicide watch!!!! I’ve never had mental health problems in all of my 64 years. I am/was a successful, healthy and articulate attorney/professor/writer/dancer. The bizarre nightmares/paranoia/hallucinations became so severe they thought I had schizophrenia. I lost my job and almost lost my husband. My doctor doesn’t believe this was caused by the Singulair but ALL of the symptoms slowly went away in the 6 months after I quit taking it. Sadly I’m not sure I’ll ever be the same person. My cognitive ability has greatly suffered."

Singulair (montelukast) for Allergic Rhinitis "I have horrible hay fever. Regular antihistamines do not work for me. I still suffer a lot if I take them. Terrible itchy eyes, runny nose, terrible asthma at night which kept me up, and a whole lot of sneezing and an achy body. My doctor prescribed me Singulair along with Patanol and Nasonex. Singulair has changed my life forever. My symptoms have been reduced by as much as 95%. I have no asthma, sneeze occasionally, and my itchy eye episodes occur sporadically but stop within minutes. I don't usually even carry eye drops with me anymore, which before would have been insane of me not to do. I'll give Singulair a 10/10 due to the fact that I've had amazing results and it's the only medication I need to make it through allergy season!"

Singulair (montelukast) for Asthma "I started Singulair 10 weeks ago. Since taking it, I have absolutely no wheezing and feel great. I have been very ill with asthma for the past 12 months, where I have been unable to come off prednisolone, and notice almost straight away when coming off it. I have been able to walk without getting out of breath for the first time in years. I must say my specialist has also at the same time started me on Xovial spray and will wean me off that in a week to see if it is the Singulair making me well!"

Singulair (montelukast) for Allergic Rhinitis "I was having bad shortness of breath that distressed me. My doctor put me on Singulair and it saved me! On day one, I noticed a big difference within an hour. They say take it at night, but I take it in the morning. Works like a charm with no side effects. I was advised to take the generic as it was cheaper with my plan."

Singulair (montelukast) for Asthma "Singulair is an effective medicine, but it can have significant side effects. I experience a foggy head and depressed mood. I have also experienced muscle cramps in my back while on this. I have noticed, in reading through the comments, that quite a few people are suffering from some form of side effect from this medicine. One recommendation: I talked to my doctor about cutting the dose in half, from 10 mg to 5 mg. I now take a children's 5 mg tablet. I still get relief but don't experience the same level of side effects."

Singulair (montelukast) for Asthma "I was prescribed this for asthma. I suffer from really bad cedar fever, which is a problem in Texas. I am a rather slim female, and at first, my doctor gave me the regular adult dosage. It was too strong. I had heart palpitations and almost called 911 once after taking it. I requested my doctor give me an adolescent strength dosage - which he did. That worked much better. It still is very strong, and it knocked me out, but I didn't have to worry about calling 911 or not waking up from it. Asthma is tough to treat. Medicine is necessary, but sometimes the meds are as bad as the disease. My advice is to start with the lowest dosage your doctor thinks will work. You can always take more if necessary."

Singulair (montelukast) for Asthma, Maintenance "The inhaler from the allergist didn't help my breathing problems. I always felt the fresh air I breathed in only got halfway down and then hit a filter of some sort. I had wheezing and whistling every day at the end of my exhale. The inhaler didn't help. I was out of breath from the slightest activity. I got a prescription from my family practice doctor for this. This has eliminated my wheezing and out-of-breath feeling. I'm allergic to just about everything year-round. It did not eliminate my need for allergy medication, but it has made my breathing perfect. I wouldn't ever want to do without this medication."

Singulair (montelukast) for Allergic Rhinitis "I was able to eliminate the use of four allergy medicines while using Singulair. I don't have asthma or any lung congestion, but my sinuses just wouldn't stop for anything, regardless of what antihistamine I was taking, whether in pill or nasal spray form. Singulair allowed me to sleep without a cough drop in my mouth and to breathe all night through my nose (something I haven't done in over 10 years)."

For Asthma "Like many others on here, Montelukast was a miracle drug for me in the asthma department. The wheezing, excess mucus, and difficulty breathing issues all vanished. However, this drug caused severe depression, panic, anxiety…it was unbearable. (As many have mentioned on here) I went down to the pediatric dose 5mg. Worked wonders. I got all of the asthma relief benefits, and the psychological issues disappeared. I encourage posters to talk to their dr about this dose as it seems that commonly the 5mg will work just as well for asthma relief without the mood changing side effects."

Singulair (montelukast) for Asthma, Maintenance "I have been on Singulair since it was first on the market. This medication has given me a life that is free of fear from episodes of asthma attacks. Before this medication, I was using a steroid inhaler and short-acting and long-acting inhalers. Not to mention the nasal spray and the allergy medication. Five medications versus the one of Singulair, plus a fast-acting inhaler for exercise or shortness of breath."

Singulair (montelukast) for Allergic Rhinitis "This product seemed to help with my allergies somewhat, but after several months of suffering a large increase in migraine headaches, my neurologist and I decided to stop using Singulair. The constant tightness in my head was gone within a week. It seems that this is a common side effect of this medicine. Migraine sufferers beware!"

Singulair (montelukast) for Asthma "Asthma all my life (40 years old) but wanted to cut down/get off the steroid inhaler (Symbicort) as it does lead to weight gain, hunger pangs, and bloating of the 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. Symbicort in the morning (Symbicort users will concede it's like drinking 10 cups of coffee) 2. Take a half of Singulair before bed (I have the best night's 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 Singulair, I sleep like a baby and wake up completely refreshed."

For Asthma "Day 4 of taking this and I decided to venture online to see if I’m crazy for feeling the way I feel. I feel as if I can breathe, but it feels difficult to. I have more anxiety and a fast heart rate. Before the medicine, I would wake up with a lot of phlegm in my throat, I do wake up without any on this medicine. Yesterday, I had bad thoughts about isolating myself from my family. Don’t think I will continue this medicine. At the end of the day, it’s chemicals we are putting into our bodies and nothing natural. Sometimes it would do more bad than good."

Singulair (montelukast) for Asthma, Maintenance "I've been stepping up and up since I was diagnosed with asthma. First, it was just Ventolin, then we added Clenil Modulite, then Seretide 50/25 at Christmas, up to Seretide 125/25 a few weeks later, adding in Avamys nasal spray for hay fever and Acrivastine for hay fever and Type 1 latex allergy, then finally adding on Montelukast. Sadly, unlike some of the other people on here, I haven't been able to get down to just Montelukast. However, I'd say it's a miracle pill! I play ice hockey, and overnight I went from tight chest and coughing and wheezing after hockey (I have CVA, so wheezing is weird) to being totally fine. I still struggle if I max out, so I have to change out regularly, but I play forward, so that's easy enough. It's just great!!!"

For Allergic Rhinitis "DO NOT GIVE THIS MEDICATION MONTELUKAST TO CHILDREN!!!!!! I never write reviews. I am writing this one because NO child should have to endure what my child went through on this medication. Dark thoughts, rage, tantrums, depression, unable to sleep, night terrors. Years of going from specialist to specialist trying to figure the cause and treatment. Finally found a doctor that said to stop the Singulair. My child is grown now. This drug stole his childhood. I know they say that you should take these reviews with a grain of salt because there are a million people out there benefiting from this drug not writing reviews. Not ONE person should have their brain function impacted this severely from a medication. And children can’t always verbalize how they are feeling. Please think twice before giving this drug to your children. There are support groups on social media regarding these horrific side effects. Thousands of parents recounting similar side effects and worse. Some child/teen suicides."

Singulair (montelukast) for Allergic Rhinitis "Yes, I think this medicine works in treating allergic rhinitis, but after not being able to sleep at all the night I took it and being extremely agitated with mood swings tapering off into the next day after a full night's sleep, I will take it no more. I think each person needs to weigh the benefits versus the side effects for them. Everyone is, of course, different and each responds in their own way to all of these medicines. Just monitor your reaction to the drug closely if you do decide to use it and make the right decision for you to continue it or not."

Singulair (montelukast) for Asthma, Maintenance "I have used this drug for over 15 years. I have asthma triggered by inhalants, and the original version has totally controlled my symptoms. I used the generic when it came out because of cost. I started having mild asthma symptoms within a few days. When my local Target switched to another generic, I developed hypersensitivity pneumonitis, which was diagnosed after over $20,000 in lab work and a bronchoscopy. Back on original Singulair, and no problem again. It really controls my asthma and allergic reactions."
