( she actully slaps her older brother.) 3) complains of tummy ach. 4) Stops breathing at nigh time.. Theres not one night that goes by that i get to sleep alone. because im afraid she will stop breathing. | Every since she's been on singulair i've noticed at night that she stops breathing. i have to set her up right to get her to breath.. Its very scary. I read a lot of comments about the meds but didnt think anything of it... tomorrow we are going back to the doctor.. Something just isnt rite. Shes always in a bad mood, and sometimes she hits on her brother (older then her) which isnt like her. And also she tryies to hit me. I hope there is something else we can try because Singulair isnt it.... | F | 4 | 1 years 5 1X day | 10/27/2011 | 2 | allergy | My 4 year old grandson was given this medicine for an allergy episode. On the 3rd night of taking it, he was having a problem staying asleep. He would begin to fall asleep and then wake me up to let me know "door closing" noises were waking him up. He also told me that he was having a bad dream that woke him up. He was not able to go to sleep for a long time because the "door closing" noises would not stop. He also complained of his leg being "asleep", but he had not done anything that would cause this to happen. His leg was numb for several hours. The next day, I double-checked on the side effects of this drug and was concerned enough to stop giving it to him. We've had no more "door closing" sounds or his leg being "asleep". His Dr. was not concerned at all. I believe this drug was causing my grandson to experience auditory hallucinations, nightmares, and numbness of the extremities. These are all possible side-effects from t | M | 4 | 3 days 4mg chew 1X day | 3/13/2011 | 2 | ALLERGIES | BAD DREAMS, | F | 4 | 2 years 4 1X day | 1/19/2011 | 2 | allergies | wild mood swings; manic behavior; hysterical crying | Our Ped. Prescribed Singulair for our daughter in addition to Zyrtec for constant allergies, post-nasal drip, and mucus. When a 4-y.o. comes to you and tells you that she had a "freak out" in school, you know that there are problems. Each night at home she would burst into tears hysterically and scream on the top of her lungs at the drop of a hat. The episodes would last about 20 minutes. The moment I stopped the meds, her behavior went back to normal. It did help her sinus issues, but the side effects were not worth it. Reading all of these comments makes me realize that I was not imagining this as my Ped. suggested. Thank you for your posts. | F | 4 | 4 days 4 mg 1X day | 6/13/2010 | 2 | Allergies, possible asthma | Wow! I am so glad to have found this site! I came on here to see if there were any negative effects to stopping singular, as they warn you on the label. My son started this at 3 and we've had a miserable year and a half! He became aggressive toward others, unable to control himself, and a complete nightmare. At his 4 year check up they recommended seeing an OT for sensory processing disorder. We have eliminated all processed foods, sugary drinks etc....well, I have not refilled his prescription in the last month and he has been an absolute angel. Honestly, he is a new child and we are all solo happy! I can't believe it has taken me so long to figure this out. | M | 4 | 1.5 years 1X day | 11/19/2010 | 2 | Allergies | Aggression, Anger, Defiance, Crying and Loss of Appetite | My 4 year old has seasonal allergies and was given Singulair on top of his normal regiment of Zyrtec. From day one of taking the Singulair chewable tablet he became defiant, and uncontrollable. It has gotten much worse as we continue to give him each dose. I have stopped the medicine after 3 days and have already seen improvement. | M | 4 | 3 days 1X day | 3/20/2010 | 1 | allergic rhinitus | agitation, hyperactivity, deliberately unfriendly behavior, oppositional, defiant, bad dreams, tempertantrums, kicking, aggressive behavior, talking too much | My son is going off tonight...a normally energetic kid has become overly aggressive, running into us, head butting with force, defiant, combative, purposely antagonizing. He is calm at preschool and within seconds of leaving is yelling, jumping, hitting - unusually aggressive and agitated. He will talk incessantly and then just crash and fall asleep. His emotions have been on a roller coaster. This stuff if awful. I feel horrible he lasted this long on the meds. | M | 4 | 10 weeks 4 mg table 1X day | 2/3/2010 | 1 | seasonal asthmatic symptoms | mood swings, night terrors, nightmares, anxiety attacks, agressive behavior | I actually left a comment back in December about my 3 yo taking the drug Singulair. I wanted to update, because I know that responsible parents are checking these sites hoping to learn more about the medicine! My son was actually diagnosed with post traumatic stress disorder after only being on this medication for FOUR DAYS! The hallucinations he experienced while on it kept him from sleeping in his own room for FOUR months, and we actually had to switch his room to a different room, completely redo the paint, covers, furniture, everything. It was a NIGHTMARE. Finally, four months later, he is returning to his old self. We actually have switched pediatricians because she again prescribed Nasonex after knowing everything we went through with Singulair...sure enough, the side effects are the same. Parents, please take caution. These are adult drugs they are giving to children. | M | 4 | 4 days 1X day | 4/10/2010 | 1 | Allergies | Aggression, zoning out, angry, mood swings...and more. | My 4-year-old son has taken Singulair for one year. While his allergy symptoms improved somewhat, his personality completely changed. Yesterday I was checking on some other things and happened to stumble on this site. I felt like I was reading my son's story over and over again. He became very aggressive and defiant. He became very anxious about random things. He would obsess about things. He began doing things that were off-the-wall and mean, and when I asked him why, the answer was always, "I don't know." He began repeating himself constantly - both in a stutter-like manner (repeating the same part of a sentence over and over and over) and also repetitive if I didn't respond to him immediately(which really annoyed me). He never seemed happy...always brooding, even when getting his way, things weren't right. This may sound ridiculous, but in one day, he is 100% better. His teachers said, "He was a completely different child. He got along with everyone, was helpful, happy and patient..." Since we've been home, I have not had to ask him more than one time to do something (which I have had to do more times than I can count...it would usually take me asking 5-7 times and getting pretty angry to get him to do something). He has been relaxed and happy. He has not gotten upset for no reason. He has not repeated himself (in any fashion) one time. I'm praying the day isn't a "fluke," but I feel certain it isn't. | M | 4 | 1 years 4 mg 1X day | 9/13/2010 | 1 | Seasonal asthma | Mood swings, lower frustration tolerance, easily saddened, throat clearing, humming, eye rolling, head turning | We started our 4 1/2 year old son on Singulair per pedatrician suggestion due to seasonal asthma. Previously we treated him with a nebulizer (zoponex/pulmicort) as needed. Our pediatrician suggested Singulair as a daily remedy so we started him on it once the school year ended (first week of June). During the first two weeks we noticed some behavioral changes (easily frustrated, VERY emotional, intense play) as well as sporadic humming, mostly while he would be engaged in watching TV. When we would ask him why he was doing that he would say "I don't know; it makes me feel better". This then led to a persistant throat clearing the following week and now, out of the blue, he has started repetitively turning his head as if he is looking at something next to/behind him. This is now happening in a wide range of environments (watching TV, playing, walking, during conversations). He says it "makes his eyes feel better". Once the head turning began, and we looked at how these symptoms had developed, we determined that this could have something to do with the Singulair so we immediately took him off. It has been over a week now and he continues to repetitively turn his head, sometimes as many as 15-20 times a minute. Needless to say we are a bit concerned and are hoping that this decreases over time since these behaviors seem to result from his 3 week Singulair trial. Updates to follow... | M | 4 | 3 weeks 7 mg 1X day | 7/8/2010 | 1 | Asthma | Mood swings not listening to a word we say, strange behaviour experienced after just 2 days of taking the medication. Kicking, hitting out of character behaviour | M | 4 | 7 days 1X day | 4/19/2011 | 1 | asthma | very violent behaviour, uncontrollable crying, hallucinations, angry about everything and everyone, panic attacks, anxiety legs itching, abdominal pain, potty accidents | After Singulair I stop recognise my child that was the worst thing I did by giving her this drug. She didn't had side effects till about 5 month from starting the drug and I thought that she is "save" I was very rong. I did my research about Singulair before she started taking it and I knew all the side effects but I was thinking this won't happens to me but it did happen.I'm hopping that she will be ok and I will have my little girl back. When I ask her why she is behaving this way she always tell me " I dont know" and that is hart braking.SINGULAIR SHOULD BE BANNED!!!! Don't take it, I will naver give this to my child again. | F | 4 | 12 months 4 1X day | 10/13/2011 | 1 | allergies and asthma | severe anxiety, hallucinations, unable to sleep due to terrifying dreams, self-harm behavior, sadness, agoraphobia, separation anxiety | My son has been on Singulair for 4 years now and is 4.5 now. On April 22, 2011, he developed severe separation anxiety, agoraphobia, hallucinations, severe sadness, self-harm behaviors, and difficulty sleeping due to terrifying dreams. Over the course of three days we were in the emergency room 3 times due ot this behavior. On the 3rd emergency room visit, he was admitted to Helen Devos Children's Hospital. Doctors were baffled at his behavior using Ativan, Versed, Haldol, and Risperidone to attempt to help. We had to put restraints on him as his symptoms increased in intensity to keep him safe as he was trying to bite off his fingers, scratching at his skin, and banging his head. He had brain scans and an EEG. He was seen by neurology, psychiatry, infectious disease, toxicology, etc. After being hospitalized and with no relief from the anti-psychotic medications for 3 days, a psychiatrist found infomation on the internet about psychosis in children who were taking Singulair. With no answers yet, and nothing else to do, she tried taking him off of the drug. With in 3 days, he was back to normal, and happier than ever. He's been off the drug for 12 days. He has had 3 episodes of anxiety attacks since then, but nothing like he had in the hospital. Are you going through this too? PLEASE contact me! | M | 4 | 4 years 4mg 1X day | 5/9/2011 | 1 | Asthma | thoughts of dying, scared, bad dreams, very short temper, aggressive, hyperactive, angry complete change of personality | My daughter was prescibed Singulair after a hospital admission. Her Asthma is thought to be triggered by viruses. The tablets seemed to have good effect with regards to her Asthma. She has been in and out of hospital too much in her short life and i was really hopeful that we had found something to help her. A month later her baby sister was born, she became very aggressive, would get extremely angry at the smallest thing and scream and shout, she had nightmares about fires and was scared to stay at friends who had an open fire. She would hit out and not listen, she was impossible to reason with and could not sit still at all. Her pre-school teachers started to ask if she was on Steriods as they knew these made her hyper, but she wasnt. This drug has it's place, but it's not right for my child, her behaviour was blamed on having a new baby around, i felt awful when i realised. After a week of stopping it she was calmer, after three i had my lovely affectionate, good little girl back, be very careful to monitor side effects if you have to try this drug, it certainly doesnt seen to be good for alot of children. | F | 4 | 1 years 2mg 1X day | 10/9/2012 | 1 | seasonal allerigies/asthma | my son's behavior changed dramatically after 5 days on this drug. he became aggressive, crazy, ultra-sensitive. i took him off after finding this web site. thank you all!! he is back to normal after three days off and using nebulizer as before. | this drug contains aspartame, something my pediatrician did not tell me. aspartame gives me headaches and makes me "foggy". i stopped drinking diet coke years ago because of the effects. | M | 4 | 5 days | 2/24/2006 | 1 | Allergies | My 4 year old son has been taking Singulair for three weeks. We immediately saw a behavior change. He became hyper and aggressive at school. He had an episode where ittook three teachers an hour and a half to calm him down. He said he doesn't know why he got so upset. He has been competely out of character for the past couple of weeks. I am so glad I started to research this medication. Last night was his last and final dose. My son is somewhat excited anyway, this took him over the top. | I wish healthcare providers would let parents know the possible side effects of this medication. | M | 4 | 3 weeks | 4/26/2006 | 1 | Allergies | My 4 year old daughter was halicunating. She would sit up in bed and scream for me to cover her eyes. Each night she saw bubbles that would "painfully" pop by her face. Also, she wet the bed for the first time in 1.5 years. She cries over every little thing and is emotional. I am stopping this medication right now. I can't believe this is on the market! I am furious! | F | 4 | 3 months | 4/4/2007 | 1 | asthma | extreme sensitivity, irritability, aggressiveness, depression, anxiety, difficulty sleeping. | I am filling this information in based on experiences with my son. Singulair was a miracle for us when he first began taking it just after his 2nd birthday and worked well for the first year. At the beginning of his 2nd year on the meds he started showing the symptoms above. We took him off the singulair and maintained his other asthma meds as previously prescribed...the symptoms disappeared completely after about 2 months. No other changes to his meds were made. | M | 4 | 2 years | 11/28/2004 | 1 | asthma/allergies | My 4 yr. old son began having huge meltdowns which would last for and hour or so. He is usually very easy going, but was now having rages in which he would cry, scream, bite, kick, hit, and require someone to hold him to keep him from doing these things. Then, afterwards he would say he didn't know why he got so upset. I knew something had changed because he had never had meltdowns like this before. I realized that they started about 3days after he began taking Singulair. We stopped the medication about 3 days ago and he is gradually getting back to his normal personality. | I think this medication should be researched further in children because of all of the negative behavior side effects. | M | 4 | 7 days | 4/20/2007 |
