For Asthma, Maintenance "My 4-year-old son was on this for a year. It worked wonders for his asthma but made him a very violent and aggressive child. We didn't notice the changes in his behavior until he had been on it for over 6 months. His fits of rage became more and more frequent. We finally decided that we would take him off to see if the Singulair was the cause. We noticed changes in him the first day he was off of it. He is back to being my sweet and loving child with no rage and no violence. It is a great drug for those that don't have this side effect."

For Asthma, Maintenance "I have had Asthma all my life. This medication CHANGED my life. I have always used albuterol (inhaler and nebulizer) for fast-acting relief, along with steroid preventative inhalers. Two years ago when I was diagnosed yet again with pneumonia, my new doctor prescribed Singulair. I am an active person who likes to run etc. Until Singulair, I had never in my lifetime run without having to use my albuterol both before and after. Not only that, this year I made it through flu season without developing pneumonia. Until I used Singulair, I had never known what it felt like to be 'normal'. To run and exist without having to stop because I was wheezing and couldn't breathe."

For Asthma "Since taking Singulair, my condition has improved dramatically. I no longer wheeze, and I sleep well. I have been a chronic asthmatic for 54 years. Now, I have been given a new lease on life. I am so happy and active. It's an emotional thing after suffering for so long."

For Asthma, Maintenance "I have been on Singulair for less than 1 week. I have noticed that with the slightest bump I bruise easily. My mouth is dry, but my throat is not closing in. I have been sleeping better and have been more active. Still take allergy medicine occasionally, Advair and blue puffer. Wowzers."

For Allergic Rhinitis "I used to take two Benadryl every night just to breathe at night. I decided to go ahead and see an allergist to get allergy shots. She gave me a script for Singulair. It really, really works! I have been taking it for over two months now, and I am thrilled. I quit buying 100-capsule bottles of Benadryl just to breathe at night. I have not had any side effects. I don't wake up nauseous, and I don't go through a million tissues anymore. I have just started my shots, three shots twice a week (6 shots a week). I have heard Singulair doesn't work for everyone. My allergist said it works best for patients with severe allergies and not as well for those with mild allergies. I am hoping my body doesn't get used to the Singulair and it becomes less effective like it did with all the other prescription allergy medicines. Time will tell!"

For Allergic Rhinitis "Medication works well but has some crazy bad side effects. First time I took it, my allergies were from high pollen counts and mold, and I was coughing every 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."

For Asthma, Maintenance "Singulair has been a blessing for my asthma. However, when I was switched to the generic in October, all of my asthma symptoms came back: wheezing, shortness of breath, and the use of an inhaler (which I only used prior to exercise) several times a day. My doctor has written me a prescription for brand Singulair. The pharmacy gave me the three pills they had in stock and ordered the rest to come in tomorrow. I did the same thing a few weeks ago with another pharmacy, and their distributor no longer carries the brand. Hopefully, this will not happen again tomorrow and I can go back on the brand Singulair. Since the problem with the generic, I have been on Prednisone, Symbicort, and two nasal sprays to try and get my asthma under control."

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!"

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."

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."

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, 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 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 Allergic Rhinitis "I have been taking Singulair now for 3 weeks. The only problem I find is, I take high blood pressure medication and my blood pressure has been normal for ages, but Singulair has made it high. I've been watching my BP morning, noon, and night. In a month or so, if it doesn't go down, I will stop taking it or talk to my doctor. But, all in all, it sure does work great. I can breathe all the time. And I wake up without a very bad stuffy nose."

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, 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."

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."

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!"

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."

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, 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."

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!"

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 I 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."

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."
