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  fluid on ears, difficulty breathing My son changed completely in the course of one week of this medicine. He has been hyper, unfocused, and full of fear and anxiety (nightmares, other fears). He has had intense stomach pain as well. He has dissolved into tears in situations he would have normally handled with ease. He's off the medicine and will not go back on it again. M 8 9 days

 1  exercised induced asthma it was for my son who was 1 1/2 at the time, within minutes of taking the granulants he began projectile vomiting. He began acting in what I can only describe as a bad trip. He was running back in forth from myself to my husband screaming in terror as if he didnt know us. he would look around like he was seeing things flying through the air. I told his doctor who said to try it one more time to see if it was the "Nausia" so we did and got the same results. We immediatley took our son off of this prescription. M 1 2 days

 1  Asthma My 7 year old daughter was prescribed Singulair for asthma, 5mg once daily. After one week on the drug she began waking up in the middle of the night, and after 2 weeks she began experiencing sudden and severe side effects - including depression, inconsolable crying, bad thoughts, paranoia, anxiety, obsessive thoughts (obsessed with food’s expiration dates), low self-esteem, and fear. When asked why she cries and says the things she says, she cannot explain it. I spoke to the pediatrician about this symptoms and he had never heard of them and dismissed my concerns, he even said it would be the first time this happened to someone in Latin America; he also questioned my “internet sources” when I told him I had done research on the internet and explained what I found out about the drug. We stopped the Singulair after a month of taking it. Now it's been 7 days since stopping the drug and she's slowly recovering. Furthermore, her new Pediatrician agrees that Singulair This shouldn't happen to a child; this drug shouldn't be prescribed to children at all. This has been a horrible experience for my daughter and my family. F 7 30 days

 1  asthma My 5 year old son changed dramatically. Self hatred, unfocused, no joy, depression, stomach pains, chronic sinusitis, rage, suicidal thoughts (yes he's 5), thought everyone hated him, extreme emotional sensitivity...the list goes on and on... He's now been off it for a month, and we have our loving child back again. This is a poison to some, please be very cautious if you are someone you know is taking it. Remember children can't put into words what adults can, look for the smallest of signs. M 5 6 months

 1  asthma extreme irritability,violent temper tantrums,tics,extreme sensitivity,terrible nightmares,anger My son was taking this drug for years and sadly I never had any idea that this could be the root of our problems. We even had him seeing a therapist to try and help with the behavior and anger. He has been off for 5 days and already I have seen a drastic change in his personality and behavior. I feel as though he was a sweet boy trapped in an angry body for years just trying to get out. Had NO idea Singulair produced these side effects. Not a drug that should be prescibed to children. The changes in the last week are truly very remarkable. M 7 4 days

 1  Allergies Mood swings, temper tantrums, aggression, irritability, nightmares, and poor appetite. My son started taking Singulair to combat repeated ear and sinus infections. At first, there was no noticeable change in his demeanor until recently. In the last several months, his mood changed and we were at a lost to explain the aggression and irritability. We were told about the recent studies and found this website and immediately took him off the medicine and noticed an immediate change in his demeanor. We had our happy, easy-going son back.

 1  allergies Severe depression, mood swings, aggression, lower muscle pain, nightmares, poor concentration If you are thinking of putting your child on Singulair...don't do it. Our daughter was on it for 3 months and the side-effects were so severe that we were considering taking her to therapist. She immediately started complaining of leg pain, and then the nightmares started. Within a month, her personality began to change and she became very violent and sometimes depressed. We didn't even recognize her anymore. She has been off Singulair for 3 months now, and she is back to being herself. She can sleep again and her pleasant nature has returned. Singulair was a nightmare for us! F 4 3 months

 1  chronic asthma I had given this med to my 4 year old son since 06/07. We started experiencing negative side effects about 3 months ago. He was weepy, clingy, irrational, and mean at home. Things he normally loved to do, he began to be afraid of and have anxiety over situations. I saw on the news FDA was investigating this drug and I immediately called his pediatric pulmonologist. I feel uncomfortable giving this drug to my child. As of today, I have discontinued use of singular. We will see if his behavior improves. I am praying that it does. M 4 10 days

 1  Cough-Variant Asthma My 4 year old son experienced Tics while taking this medication (blinking his eyes, shaking his head, opening and closing his mouth, clearing his throat, making a sqeaking noise). Once we took him off the Singulair, it took a few weeks,but we did notice an improvement with his Tics (he had never had Tics prior to his taking Singulair). He was also taking Albuterol - maybe it was a combination of the drugs, but honestly, it was the scariest thing we ever encountered with our son. In observing him for a 15 minute period, he would shake his head 25 times (and it was a violent head shaking - like that of a dog shaking off water) and open and close his mouth 6 times (like he was trying to unblock his ears). He seemed to constantly make the sqeaking noise. It has been almost 3 months since we have taken him off of Singulair, and it appears that the TICS are finally gone. I would NEVER recommend this drug to anyone - it caused such stress and trauma in my family. We talked to 4 separate doctors, and only one doctor agreed that in his opinion, the Tics were triggered by Singulair. I do believe that my son was probably genetically pre-disposed to Tics, but absolut M 4 6 weeks

 1  Allergies and Asthma Aggressive behavior, temper tantrums, nervousness, anxiety, depression, hair loss, hyper,moody,unusually tired in the mornings. My now five year old son was prescribed this medication when he turned two. Approximately 6 months after taking it, his entire demeanor changed. He turned into a very moody, angry, sad child and started losing his hair. The pediatrician, allergist, immunologist,dermatologist, and specialists all said that it could not be the medication causing his hair loss. He now has no hair at all. Recently, I have found links to Singulair and hair loss and I am ANGRY. My child has been treated for Alopecia for now 18 months and this terrible drug could be the cause. As soon as I found the connections to his behavior changes and hair loss I took him off the medication. It has been three days now, and I have already noticed a modification in his agressive behavior. Parents should be aware of the harmful affects of this medication. M 5 2.5 years

 3  Asthma excessive/rapid weight gain, thirst (especially in afternoon), some anxiety, trouble focusing on tasks I am so relieved to have found this web site. I saw an article in the news today and did some research. My daughter has gained an unexplained 10 pounds in less than a year (without gaining much in height like you would expect for that kind of weight gain in a child) & she is a very healthy eater for her age. She eats virtually no trans fats, drinks no fruit juice/soda, swims twice a week, plays basketball, softball, etc...I can't believe that Singulair could be responsible. The worst part is she worries about being heavy & I keep telling her she will grow out of it. It could also explain her anxiety and trouble focusing (which I attributed to her age). I'm going to take her off today & see what happens. Her asthma is not completely under control anyway and we are seeing the doctor in a few weeks for more options. How scary. F 9 18 months

 2  Allergy Induced Asthma Mood swings, irriatiblity, sleeplessness, night terrors, Ear infections, clingy, hitting sibling. We added this medication to his asthma routine as he would have a persistant cough that sounded like a seal for the allergy seasons. Well, I noticed an increase of mean behavior toward his sister, he was waking up persistantly throughout night. Would wake up with night terrors and not know who I am. TOOK forever to calm him down. He also turned from an easy going kid, to a defiant child and also very disturbed whiny kid. Took him today to doc for ear infection, which has increased since putting him on this medication. I am NOT giving him his dosage tonight. My son is normally a sweet boy, but has since been turned into a monster! Thanks for all the comments! You helped me determine it's not just in my mind!

 2  allergies moodiness,loss of focus,"bouncing off the walls" My son was prescribed Singulair after I had tried many other allergy meds-antihistamines and decongestants and had "moody" reactions to them. When the Dr. suggested Singulair I thought it would might work better since it was a different type of med, and I had worked around it in the past(I worked at an ENT office) and never heard any complaints. After ten days on the med the same moodiness, hyperactivity, and sensitivty started. His kindergarten teacher also noticed the change. I am stopping the med immediately. I thought it was just my son being sensitive to the med, now I realize he isn't the only one. M 5 10 days

 1  Persistent Asthma The side effects of this med on my 3year old were devastating. He went nearly 48 hours without sleeping. He couldn't even maintain eye contact with us he was so hyper and aggressive. He would go into tantrums and roll around on the floor. Not at all like our child's typical behavior. He was on it less than 2 weeks as I was told these symptoms might get better after two weeks, but we simply could not put him through it and took him off. I am very concerned about the side effects of this drug. I am sorry I didn't take him off it the minute I saw the changes. I knew it was not right immediately. M 3 2 weeks

 1  asthma body aches, vomiting, night terros, moody, He only took the medication for a week. He first started spitting up a little bit of his food while having meals. Then he started with a little cough that led into vomiting. Then he started waking up at night with stomach aches. Then he started crying like if everything hurt. He did not wanted to be picked up. I found him pulling his hair and his ear lobe. I believe his ears were either ringing or hurting. All this in just a matter of days. He is not taking it today. I just called his Pediatrician.

 1  asthma aggression, night terrors, temper tantrums, oppositional behavior, violent thoughts,possible hallucinations When my daughter was 2-4 she took this. She went from an emotional child to a psychotic one. Several times she even said,"My brain is telling me to do bad things". She would cry and scream for hours. (and I would cry too) She had two horrible years at pre-school. I was "this close" to taking her to the psychologist. (and myself) I took her off the meds as it was summer and she hadn't had an attack in a long time. Thought maybe she had grown out of the asthma. When I noticed the immediate improvement in behavior I researched the medication and realized....The guilt was overwhelming Do not take this or give it to any child F 6 2 years
