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)

 5  Asthma No side effects whatsoever. My son who is now 15 began taking 10mg of Singulair daily in combination with Zyrtec. His asthma has been completely in control but it took us years to get the right drug combination that worked for him. The drugs that contained steroids consistently resulted in significant mood and behavior changes. Fortunately we have not seen any of these types of symptoms with Singular. M 15 6 years

 4  asthma, allergies headache, hallucination, insomnia, irritability, anxiety/paranoid I'm 15 years old, and I've been taking Singulair since late February of this year, so about 4 months. My asthma and allergy symptoms seemed to have almost disappeared, but just recently, I've had headaches, and I've been irritable and moody according to my mom. After reading these posts, I've discovered that some weird things I've been experiencing may be linked to taking this medication. I've had weird hallucinations, in which I've been seeing and hearing things that aren't there. At first I thought it was just because I was tired and/or dreaming, but reading these other experiences, I'm starting to think otherwise. I don't think these symptoms are bad enough to quit taking it, but its starting to worry me a bit. I've told my mom about all the posts I've read on here, and that I've been experiencing many of them, but she think I'm just a hypochondriac. Any suggestions or anyone with similar symptoms?

 3  Exercise Induced Asthma, Allergies Depression, Anxiety, Suicidal thoughts, insomnia, loss of appetite, and many more Once I started taking it, I got the side effects pretty quickly. Now, I cry every night for no reason and have really bad thoughts that I can't control. I barely sleep at night; Going to bed almost every night around 4 or 5 in the morning and sleeping throughout school which is causing my grades to drop. My friends notice my mood always changing. Sometime, I get random attacks and break down crying and not wanting to talk to anyone. it's only been 3 weeks and I hope it doesn't get worst because I don't plan on stopping. F 15 3 weeks

 2  seasonal asthma from allergies depression, mood swings, anxiety I took Singulair last year when i was 14, and it was a 5mg pill. I had a lot of anxiety and ADD like symptoms, i couldn't focus in school and my grades had a drastic drop. The anxiety and depression like moods would switch off, where I could go from being running around anxious one second to sitting just wanting to be by myself the next. This year I'm now 15, and so the dosage was upped to 10mg. I didn't know this, and so I started taking it again hoping there would be no side effects. It was so much worse this time, I started having panic attacks and crying spells and wouldn't know what to do with myself. Singulair does help with my allergy and asthma symptoms but I think I'm going to stop taking it because of the side effects. F 15 1 years

 1  allergy irrability, focus on suicide, self harm, change in mood, nose bleeds We have a 16 year old son, who has no history of depression or unhealthy ways of coping. Started a downward spiral, we did not know what was going on. He could not explain it,"I don't know" Took him to counseling for help, they did not have an answer, or see something we couldn't. Read an article on singlair, and was outraged and shocked, never Knew there was a possible connection. Stopped the medication. Waited... THe next day, our son was back. Each day was brighter and brighter. Would not have believed it, unless lived it. Have it documented by counseling as well. Hoping to follow up with someone who can get the word out. Our son's life was saved, and we would like to help others. Thank you M 15 1 years

 3  Asthma, Allergies Depression, anxiety, a studder, hopelessness, suicidal thoughts, fear, lonliness, mood swings, anger I have taken Singulair my entire life. I wish I could have my childhood back without fear, without anxiety, without depression, I dont exactly know how this drug has helped me with my asthma, nor do I know if me as a person will be different if I ever get taken off of it. I fear I am who I am today beacuse of Singulair.a All I do is stress and fear everything, I even fear talking to people. I fear telling my doctor, if I get taken off the drug, will my asthma be controllable? Will I be a different person. Maybe I'll never know. I wonder who I would be today if I didn't have asthma, if I didnt have to take singulair. All I ever want is to be accepted by people but I fear there is no one on this earth as unfortunate as me. Every day I contemplate suicide, I fear it so much I con't do it. M 16 16 years

 1  Allergy induced asthma My 16 year old daughter took the pill and the very next day she was over the top angry, aggressive and full of rage. She was put on singular on a Wednesday and I took her back to the doctor on Monday and they immediatly took her off singular. I did not make the connection immediately but her behavior made me take a second look at the presicription side effect label from the pharmacy. F 16 5 days

 1  Asthma/Allergy nightmares, hair loss, depression, suicidal ideology. I am posting on behalf of my daughter, age 16. She was on Singulair for approx. 6 years, switching over to the generic form August 2012. Mood changes were gradual and attributed to "teenager". Five weeks ago, the thoughts of suicide were dominant and she was removed from the drug asap - they are unsure if it is her age or the switch to the generic form that triggered this. My question is - how long before the aftereffects of this drug go away? The hair loss has just started improving but the suicidal thoughts are still present. (yes, she is under a doctor's care and seeing a therapist) F 16 6 years

 1  Asthma This drug caused nightmares/night terrors, hallucinations, suicidal thinking, aggression & extreme anxiety to the point my son would not leave the house. After 3 years off, he still suffers severe anxiety & sleep problems. It worked well for asthma but the neuropsychiatric side effects were horrific. Would not recommend it especially as some side effects last long after stopping. M 16 2 years

 1  Allergies/Asthma My son started taking singulair when he was very young. I took him off of it for a while but his asthma flared up. He started back on it and he began to get depressed, moody, and was waking up hearing screams. He also heard someone calling his name and said he felt something touching him. He had anxiety and didnt understand what was happening to him. I spoke to his Dr. and they said to keep giving it to him. Thank goodness I didn't listen He has been off of it about one month and the side effects have decreased but aren't completely gone. I would never use this med It needs to be off the market.
