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  Allergy and exercise induced asthma Anxiety, depression, moodiness, irritability, low self-esteem, reduced sex drive, racing negative thoughts, reduced motivation to do things I normally love to do, emotional "melt downs", reduced ability to cope with small problems, enhanced PMS symptoms, etc, etc, etc! I am normally a very upbeat, optimistic, funny person, and have been my whole life. After 2.5 years on Singulair, I no longer felt this way. Because the changes were so gradual, I truly believed that something else was wrong with me, i.e. that the symptoms I was experiencing were not drug-induced. I thought that I had inherited the propensity for depression from one of my parents and that the time had come for me to start anti-depressants. I even went so far as to consider having my doc prescribe one for me! After my husband told me of the link between Singulair and suicidal thoughts (which I did not, thankfully, experience) and reading the postings on this website, I decided to stop taking the daily Singulair (10mg) and Zyrtec (5mg) which had been prescribed for my asthma and allergies. After about two days of a real funk (withdrawal) and two weeks of extremely itchy skin (Zyrtec withdrawal) I began to feel like my old self. Happy, laughing, able to cope with things, not menta F 47 2.5 years

 1  drug related rash Numb lips and roof of mouth,cry for no reason and just feeling like I'm flipping out. Can't concentrate and focus. Also can't sleep. Was given this drug in the ER with steriods, to stop a alergic reaction from Factive.I was fine for about 5 days. On the 6th day I thought I was going to loose my mind after taking Singulair. Could not stop crying, can't focus, and don't feel like I have any control of my body. I'm so glad I found this site. I will stop taking it tommorrow and see if I can get some relief. F 47 6 days

 1   I have written before. Side effects are horrific-barely worth the benefits. Read this one now. We have to take control. Allergy Medication Linked to Suicide WNYT News reports that today, February 28, 2008, the FDA will open two days of hearings regarding communicating the possible risks of the allergy drug Singulair, which has been used by millions of allergy and asthma sufferers. The August 2007 suicide of 15-year-old Cody Miller after just 17 days of Singulair use has sparked interest in the drug manufacturer Merck's notification program. Cody's mother said that by the second week of her son's Singulair use, he began having trouble sleeping, followed by "three days of really falling, negative emotional meltdown" before he took his own life. Neither they nor their doctor had any awareness of Singulair's danger. Although the company says that it has notified pharmacists and physicians of potential dangers, Singulair's warning didn't include suicidal thoughts and actions until October 2007, two months after Cody's death. Whenever taking any medication, it's important to read existin F 47 7 days

 1  Allergy induced asthma Extream pressure in ears, vertigo, achey joints mostly hips and shoulders. Horrible indigestion with heart burn and acid reflux. Anxiety, feeling like I was going to die (which I have never had my entire life). Heart pounding and heart palpitations. Numbness with pins and needles, on face, left arm and left calf. Brain fog, forgetfulness, no get up and go. Two lung infections and I've had lung inflammation once. I believe these are all side effects of singular. Side effects came on gradually and I never thought it could be because of singular. I stopped taking it by accident ( forgot to pick up my rx) and realized my hips weren't hurting. I continued from there cold turkey. I've been off for two months now and I'm so much better. It didn't happen for me right away. Joint pain and indigestion went away first with in a few days. Palpitations were next to go.. Brain fog and numbness took about a month to get better (pin and needles went away with in a week of stopping singular) anxiety is SO much better, still have little episodes and heart pounding every once in a while. My symptoms (now I know side effects) were really bad for two years I'm hoping they continue to go completely away. Singular has ruined the last two years of my life! I thought I was going crazy. I've been to my Dr eight times in the past two years, I've been to a neurologist, and I've had a treadmill test. All because of singular. Don't take it, it will kill you or ruin your life!! I can't get these years back thank God for my husband that is absolutely amazing and just kept telling me we'll figure this out. If anyone can say how long it took them to feel 100% normal again please say how long it took. I'm praying this is not my new normal, these little bouts of anxiety and heart pounding just keep reminding me I'm not quite back to my normal. F 47 4 years

 1  Allergies Normally a sound sleeper, but nightmares, achy muscles and very poor sleep after starting singular. Heart feels like it is racing, and feel very anxious which is concerning. I will not be taking this medicine again. Far too many side effects to be used as an allergy treatment. F 47 2 days

 5  Asthma None. Because of Singulair I have not used my rescue inhaler in 6 years! Before Singulair I was using it every day. My Dr. mentioned that there's typically no middle of the road with Singulair...that it either works great for you or it doesn't work at all. F 46 6 years

 5  allergies none I have mold, tree, and grass allergies (and various food allergies not treated by Singulair). My outdoor allergies cause burning and runny nose, sneezing, sore throat, sinus infections, headaches, inability to concentrate, and light-headedness. Before taking Singulair I already had anxiety, sleep problems, and leg cramps; these things have not changed. My allergies are mostly controlled by Singulair, having mild symptoms with incidental exposure (strong mold or grass smell) or at times such as when cedar or grass pollen is very high (requiring me to also take Nasonex). I have not experienced depression or nightmares. I do not know whether I can stop taking Singulair and not have allergy symptoms; I tried cutting back to 1/2 pill this fall to wean off of it after grass season, but had to go back to the regular dose.

 5  athma and allergies none I have heard that some parents have taken their kids off due to negative side effects. Though these have been kids who have other medical/mental health issues along with asthma a allergies. The side effects appeared after several years of taking the medicaton and due to changes in life. F 46 3 years

 3  Asthma & Allergies Weight Gain Love what it does for my allergies and asthma, but not the weight gain. No other life style change at all to explain the 5 pounds I've gained in 3 weeks since starting Singulair. How can they claim weight gain is not a side effect of Singulair with all these posts?

 3  wheezing, tightness in chest Agitation, insomnia, felt aggressive and belligerent. Fortunately, I found I could tolerate greatly reduced dosages. I got the pediatric size, and now take one half the child's dose (2 mg) every other day. At this dosage, it still helps with the wheezing, and does not make me feel agitated, crazy and mean.

 3  Allergies I took Singulair for the last three years and experienced relief from my allergy symptoms. Unfortunately, the last time I took Singulair , two months ago, I started having horrible dreams. Every night I had graphic dreams where I was killed. I know, not fun. The bad dreams affected my mood. I was telling one of my coworkers about my allergies and the problems I was experiencing and he told me about the affect the drug has in some people. I stopped taking the medication, I am no longer having bad dreams, and I am back to my normal happy self. 3 Years. Only had problems this time around (past two months) F 46

 2  allergies, mild asthma can't fall/stay asleep easily then when I do bad dreams, tiredness, irritability, memory loss. sore muscles, anxiety lots of it! There needs to be more attention to who is getting this drug for some this may be a last resort and that mey be fine but with the side effects, that no one will achknowledge are real, this is not worth it for mild or moderate allergies and/asthma there has got to be a better way.

 2  Bronchial Asthma Terrible loud ringing in my ears, headaches, dizziness, trouble concentrating, spasms and squeezing pains in my chest. The ringing in my ears is driving me crazy! My lung function was at its worst during my last doctor's visit. My pulmonologist is trying his best to help me and recommended I take this drug as a supplement to spiriva. I called his office last week to tell him about my symptoms but he was on vacation. I thought I would check the internet for side effects and by virtue of comments on this site, I think I have found what I suspected. I need to get the singular out of my system! F 46 35 days

 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  Allergic Rhinitis Night terrors, reoccurring ear infections, suicidal thoughts, brain fog, loss of concentration, hair loss, insomnia, swelling, weight gain, anxiety, thoughts of death, ocd, teeth grinding at night. Had been suffering with allergies and doctor recommended montelukast. Was unable to get off the couch the first two days. Depression, horrible, terrifying dreams. Then I became convinced someone was coming in my apartment. Would wake up at night feeling like someone was in the room with me. Went back to the doctor and she assured me it had NOTHING to do with this medicine. Referred me to a therapist. Slept 10 hours a night and would come home every night and nap for hours. Constant brain fog. Forgetful to the point I could not remember my own birthday, my age, my boyfriends last name. Then became anxious about leaving the house. Started having food delivered. Would go to work and then have to rush home, wouldn't leave on weekends. Started online shopping for things I didn't even want. Then suicidal thoughts started out of nowhere. Would be in the middle of a conversation and a thought would pop up, " You should kill yourself! Throw yourself off the building at work." Terrifying! Thought about going to a mental hospital. I couldn't feel much. It was like I was cut off from my emotions. Couldn't feel happiness or joy, couldn't even cry when I was at my worst. Then my hair started falling out and when I looked it up I found this site. Thank God!!! Off two weeks and I''m not totally back to me but I see a light-except for the hair, that's still falling out.
