| 4 | allergies/asthma/persistant cough | My son has not had any of these side effects. | My son still has a post nasal drip cough but it is much better than it used to be. I wasn't aware of any of these side effects until a sticker appeared on his prescription this month. | M | 13 | 1 years 10 1X day | 6/5/2010 | 3 | Asthma & Nasal Allergies | My 13 yr old son has been taking Singulair (10 mg) for several years. I am looking for the reason that he is beginning to fail in school. Not finish assignments, not turn work in, etc. Is this the medicine or just adolesence. The medicine has seemed to keep in asthma & allergy symptoms in check, although he also takes singulair. | After reading the information on this site, I am going to use parental perogative and take him off of it to see if there is any improvement. We will see what happens. | M | 13 | 3 years | 5/1/2007 | 1 | for asthma and allergy | My son became more sensitive and very serious.Shortly after falling asleep my son would wake up with night terrors. He was really asleep but could not wake up.He was very scared and acting crazy.This had not happened since he last took the med 3 years ago. I forgot this med was the cause and now took it for 2 days and the results were the same as 3 years ago | After comforting back into bed and telling Him he was OK he eventually fell asleep.3 years ago he was taking for1-2 years and he had many night terrors. After it was out of his system he never had them again. Even if it took all asthma symptoms away it is not worth taking if a person's mind is so affected. | M | 13 | 2 days | 12/11/2005 | 1 | allergies | Prevously took 5 mg on & off for 3-4 year, but when dosage was bumped up to 10 mg, had major depression, suicidal tendencies, lack of concentration, poor vision and trouble relating to family and teachers. After reading these reviews I am going off today & hope these side effects disappear. | F | 13 | 3 months 10 mg 1X day | 5/3/2010 | 1 | asthma | severe, itchy, torso and arm rash | none | M | 13 | | 12/25/2000 | 1 | Allergies | mood changes, bad nightmares & vivid dreams, thoughts of hurting others to the point of wishing they were dead, anxieties & panic attacks, stomach ulcers, developed hyietal hernia, loss of concentration, lost 30 lbs within less than 6 weeks, choking sensation when swallowing, loss of appetite, depression, he felt like a balloon bursting in his head with 3 weeks of taking singulair. | Started taking med Nov 13, 2008. Three weeks later teachers at school recognized a change in behavior that was not typical or noticed prior to the med. The end of Dec. 2008 loss of appetite and increased mood changes and noticeable aggression toward others and unable to change feeling even knowing his thoughts & feelings were not typical or right. Jan 13, 2009 realized it was the med and he stopped taking singulair. Not only is my son still trying to recover from physical effects, he currently is trying to recover emotionally. No longer able to attend school and in a homebound education program. Would not recommend this drug to anyone. Was taken to the emergency room 3 times within the last month and a half. Was admitted to the hospital twice and a phsyciatric treatment facility once and currently going to a phsycologist weekly all within the last month and a half. | M | 13 | 1.5 months | 2/26/2009 | 1 | Athsma/allergies | I was in the 4thand 5th grade when I took Singular, and at first it seemed to work great and really helped my health. Later on, though, I started having suicidal thoughts and depression, and I was really worried about myself. I would cry a lot and refuse to go to school, and I had a lot of trouble focusing. The side effect of depression and suicidal thoughts with Singular was not yet announced, and my parents couldn't figure out why I was acting this way. Dismissing it as the recent death of a family dog, I went off Singular about 4 months later because I was switching to a day and night ashtma preventative called Advair. The changes in my behavior were apparant, however, we just thought I was finally accepting the death of a pet and moving on. A couple of years later it came on the news about how Singular caused suicidal thoughts and there were already 4 people who were on Singular that had commit suicide because of it. | It works, but it's NOT worth the side affects. Now that we all know it can cause behavior problems, depression, suicidal thoughts, and aggression, there are plenty of other medications that will work without the disturbing side affects. | F | 13 | 2 years | 9/12/2009 | 1 | Asthma | Vivid nightmares, Very Fatigued , Mood swings, Foginess, Loss of concentration especially at school, , Redness & puffiness of the eyes, Bad Headaches.....Loss of interest, vitality... Very upset not advised by Paediatrician of possible side affects, he strongly recommended, no medical instructions in the packet.. ...Searched Singular on the Internet it all makes sense now... Dr's etc, should have a duty of care to advise patients of possible side affects... These side affects are real & Singular should not be given to children, research has shown children's brains are not fully developed til early twenties, what sort of damage is this drug doing to children's long term physiological state.. I find this very disturbing & cannot fathom how pharmaceutical companies can 100% assure there is no long term harmful affects to children's brain from taking this drug.. I find it totally immoral and disturbing that companies take greed & profits over children's physiological & long term health. | F | 13 | 15 days 5mg | 4/1/2019 | 1 | Montelukast generic brand for allergies | My son has been taking this drug since he was 4 years old . He stopped taking it by 11 years old. This drug gave him nitemares , depresssion ,suicidal thoughts ,headaches, and anxiety. He doesnt want to be around people or go outside. My son likes to stay inside play his videogames and text in the phone with family. He is getting better at socializing especially with family now. He has anger issues too. I wish the nitemares would end for him. | This drug has caused my son nitemares since he was 4 years old but I really didnt pay attention to it. He stated he had them at early age. Please review this drug .. Its not a great med for children. Parents be cautious with this med. | M | 13 | 7 years 5mg 1X day | 9/6/2020 | 4 | asthma & allergies | None that we are aware of. | My 14 year old daughter has been taking Singulair for about four years for asthma and allergies. She had a life-threatening event 1 1/2 years ago and was resuscitated at local hospital and transferred to regional children's hospital. The event, which is believed to have been "Sudden Asphyxic Athsma" had come on very suddenly while we were at a family event, luckily near the hospital. Prior to this event she had not been regular in taking Pulmicort or Singulair and had been relying heavily on albuterol emergency inhaler and Benydryl (which makes her very sleepy). She now religiously takes Flovent twice a day and Singulair 5mg and carries an emergency epi-pen at all times. She seldom needs the emergency inhaler and almost never has itchy eyes and hives, even though her blood work shows a very heavy allergic load. Either the Flovent works for everything or a combination with Singulair is working well for her. The allergist changed the children's hospital's RX back down to | F | 14 | 4 days | 12/19/2008 | 2 | Allergies | Daily Headaches, Moodiness, Lethargy, Fatigue, Loose Stool, Loss of Appetite, Anger, Defiance, No Motivation, Sleeping problems (although it could be my insomnia associated with my arthritis, but most likely, its the medication) | Like many other users, I want my life back. I have been experiencing way too many side effects and it really sucks. This medication has effected my life too much in a negative way and I'm tired of it, I am definately stopping tonight. | M | 14 | 12 days 10 MG 1X day | 10/19/2010 | 2 | allergic rhinitis (pollen, dander) | My pediatrician had prescribed me singulair after many OTC antihistamines and prescription nose sprays (ex. Rhinocort, Flonase, AND Nasonex) had all been ineffective to my pollen and animal allergies. I had been making it through the 14 day trial period just fine until the last day where I broke out in hives. I was quite disappointed because until then, the singulair seemed to be working just swell. :( I didn't experience any of the mood changes, vivid nightmares, ect... Like others have been saying. I'll I would say is be careful what you are giving to yourself and your children. ~Nanners~ | F | 14 | 2 weeks 10 mg | 12/31/2011 | 1 | asthma and allergies | severe anxiety, hullucinations, paranoia, severe mood swings. | Started taking this in 4th grade, worked great for my allergies and asthma, however when the dose was upgraded to 10 a year later I started getting hullucinations, was very paranoid and scared. I took the medication on and off for five years so there would be times I would be fine then I would start in with major anxiety, fear, afraid all the time that my mother was going to die, unable to do anything away from her. My mother asked the doctors if these symptoms could be related to Singulair and they just dismissed us and said no. My symptoms got so bad I was given prozac and xanax, which didn't help. Then we found this site and stopped taking the medication immediately. That was two months ago. I'm almost free of the anxiety, not completely symptom free but feeling MUCH better. I'm able to go to school and even out occasionally with friends. This medication works for the allergies and asthma symptoms but not worth all the horrible side effects. I wish there had been better warning labels when I started this medication, I would have stopped it immediately back in grade school and I believe my life would have been much different. | M | 14 | 5 years 10mg 1X day | 2/15/2010 | 1 | Allergies | My teenager was on this and became severely depressed on it (no prior history). Took him to his doctor and she said she had never heard of this as a side effect. Said if he didn't snap out of it, she would put him on an antidepressant (which I am totally against). Took him off the Singulair and he returned to normal within a few days. | I find it interesting that now there are reports of this drug causing depression/suicide. Glad I didn't listen to the doctor and knew in my gut that this drug was making him feel this way. Watch your kids carefully while on this drug! | M | 14 | 7 days | 3/31/2008 | 1 | Asthma | heart palpitations/heart racing, mood swings, extreme rage, extreme sadness/depression, hyperness at random, mean/bad thoughts, short temper, screaming, threats to myself. | This medicine did not help my asthma much, and also contributed to mental issues. I would not, on any circumstances, recommend this medicine to anyone. | F | 14 | 12 months | 1/14/2009 | 1 | mild asthma | mood swings, anxiety, depression, aggression, outburst behavior, nightmares, diminished impulse control, suicidal ideation | My daughter went from a delightful little girl to a problem child almost immediately. That was blamed it on the fact that she was nearing her preteen years, though she didn't reach puberty until 14! When she ran out of the medicine recently I didn't renew it, and her behavior is rapidly reverting to normal, though her self esteem had been damaged by the years of ADD-type behavior. | F | 14 | 6 years | 2/17/2009 | 1 | exercise-induced asthma | 14 yr. old boy - nightmares (never had before), major problems concentrating in school, esp. math (an honor student), said he felt "wierd" and "different". | My 14 yr. old son was put on Singulair for exercise-induced Asthma. He has no other asthma problems. Within a week, he was waking up at night with nightmares and had trouble sleeping. He has never had dreams at night. He said he felt "weird" - kind of in a fog. Another problems he had was concentrating and focusing on his school work. He is an "A" honor student and had trouble focusing and rememebering things. We really noticed it with his math. We took him off Singulair and have already seen a major improvement. Just be careful and be sure you monitor your child. It did not work for us. He said that it did improve his breathing during basketball but we are looking for other options - not worth it for the side effects. | M | 14 | 14 days | 3/11/2009 | 1 | Uncontrolled asthma | Unbearable left abdominal pain, back pain , numbness, dizziness, shaking, depression , wanting to hurt myself , anger , fast heart rate , chest pain , pins and needles , not being able to sleep , nightmares, seeing things and hearing things they where not there | I started taking this bc my doctor told me to did not warn my mum or me about the side effects after about a month things went down hill with abdominal pain unable to sleep ext 6 months later no doctors could figure out what was wrong with me untill a few nights ago I seen a video and decided to look up the side effects and there it was it took me 6 month I'm in severe pain to find out it was this and no doctors figured it out I'm still in the tablet I'm waiting for my doctor to get back to me and tell me it's safe to come of DO NOT RECOMMEND PLEASE WATCH FOR SIDE EFFECTS THIS HAS RUINED MY LIFE AND IK I WONT BE THE SAME !!! | F | 14 | 7 months 1X day | 3/19/2021 | 1 | Asthma | Suicide attempts, depression, OCD. | Watch for changes in mood or personality. | F | 14 | 6 months 10mg | 10/15/2019 | 1 | Severe sinus/allergy problems | Major attitude and negativity problems that subsided after 24 hrs of not having drug in system | M | 14 | 2 days 10 | 10/24/2014 |
