| 2 | allergies | My three year old son was put on Singulair due to his allergies, however over the course of three months we noticed that he had become a child we did not know. He was very hyper, moody, irritable, and aggressive. These characteristics were totally opposite of his fun-loving, happy-go-lucky behavior prior to this medication. We finally took a chance (before doing research) and took him off of the medication and within 24 hours he was back to his normal self! This road was definitely a rocky road, even to the point where we were questioning our ability as parents! BE ADVISED!!!! | hyper activity, aggressiveness, moodiness, irritability | M | 3 | 3 months | 8/16/2006 | 2 | seasonal allergies/ asthma | Mood swings in 3 year old son. Hyper-activity, sleeplessness and irritability. Angry and agressive behavior. | At first, we thought this was typical three year old behavior. After reading the posts on this drug I am convinced that it is all a side effect of his medication. He has had his last dose and I am expecting my "good boy" back any day now. | M | 3 | 3 weeks | 8/25/2006 | 2 | allergic rhinitis | sore throat, vomiting, decreased appetite, increased aggression | My 3 year old son commenced on singulair as a trial to reduce the allergic rhinitis. Discussed with his doctor today regarding behavoural changes and possible side effects. He was not aware of behavioural changes with this medication. We agreed to stop the medication as I feel it is affecting his mood and at times uncontrollable rage. I also think is appetite has decreased. I do not believe this is 'age related'. | M | 3 | 5 weeks 4mg 1X day | 5/27/2010 | 2 | Severe Seasonal Allergies | Anger, Aggression, Hostility, Moodiness, Spaced out, Decreased Appetite, Irregular Sleep. I also noticed his face has blanched, eyes have dark circles, and he has been chewing on his hands constantly. (something he never does) | My son started taking this medication only a few days ago due to severe uncontrolled allergies. Since beginning this medicine, my son has had severe mood problems that I was attributing to a cold he caught a few days before the Singulair was prescribed. In only 5 short days I my child changed from a sweet and usually happy go lucky little boy to an aggressive and emotional mess. He stopped napping, sleeping like normal, and he has lost his appetite altogether. He yells at me, screams NO to everything I say, and he has been chewing his hands constantly for the past 3 days. The temper tantrums haven't stopped since starting Singulair. I know he has only been on the medicine for 5 days, but the fact that I noticed such a big change in his behavior to google search "singulair behavioral problems" should tell you something. Effective immediately I am taking my child off this medication. While it has been the only thing to help his allergies, it just isn't worth the side effects. | M | 3 | 5 days 4 1X day | 10/9/2010 | 1 | Asthma | Behavioral issues such as defiance, hitting, kicking, screaming, trouble sleeping, raging tantrums, hitting himself | My son has been on singulair since he as one. He is now 3. I have spent the last two years trying to figure out why his behavior is the way it is. He has been kicked out of 2 different day cares for hitting other children, throwing toys, throwing chairs, knocking over tables etc. He can go from being perfectly fine to raging like this is 2 seconds. I have had him evaluated and everyone says it's just his age he will grow out of it. In the mean time, he was recently kicked out of another day care. After reading the Singulair website, I asked his pediatrician if this could be the issue, she said no. Yesterday I found this site and after reading all the other comments from parents with similar problems, I have stopped the Singulair. I have no idea how long it will take to get out of his system. I heard up to 6 weeks. Hopefully I wil see a change soon. | M | 3 | 2 years 4 mg 1X day | 3/10/2010 | 1 | Asthma & constant resp infections | Agression, screaming, tongue twitch, | My gorgeous kind hearted little boy turned into a monster within a day of having this horrid drug. We were warned about possible side effects but that they were highly unlikely & I was so keen to just get him well I foolishly gave him the chewable medication. As of the next day he started screaming uncontrollably, hitting his siblings, throwing everything he could when couldn't get on way, throwing things at our dog, being completely defiant and totally out of character. In last two days keeps sticking his tongue out and twitching it constantly which he has never ever done before. Have probably only ever had to put him in time out a handful of times in past but this week he has spent nearly all of his days being sent to time out. He even bought me to tears today as he tried to hit me which has never happened before. Thank goodness i found this site. No more singulair for him and I feel so terrible for thinking the worst of him when now I KNOW it's the drug and not him that made him act like that, and feel worse still that I let him take it! A person can't change their personality overnight however that is exactly what happened when i gave my son singulair. DO NOT USE IT - | M | 3 | 5 days 1X day | 2/4/2011 | 1 | allergy symptoms - cough/congestion | Temper tantrums, crying over smallest things, agressive, pushing, bad dreams, potty accidents, generally out of sorts | My 3 yr old son was prescribed this medication in lieu of Zyrtec while awaiting allergy testing. We go to the doctor tomorrow for the tests. I stopped giving him Singulair today. I have seen a DRAMATIC change in his mood. He is aggressive towards me and his sisters and father. He does not want to participate in even the mundane activities of the day like taking his sister to school... throwing himself on the ground, crying, hitting. He never did this before. He has also had 4 pee accidents in two days. This is a first. He has not had an accident since he was potty trained 6 months ago. No other changes have taken place in our family, no other trauma I can point to. He suddenly just felt "bad". He doesn't know why when you ask him. I had some reservations before going on the medicine when I read the indications on the package. I asked his current Pediatrician and his former Ped. and both felt it as safe as their children were on it. This is just too coincidental for it to be a behavioral problem that showed up out of the blue two days after starting this medication. Thank you for the posts. It just confirmed "that little voice inside" that said something was wrong with this medicine. | M | 3 | 5 days 2.5 mg 1X day | 12/7/2010 | 1 | allergies | insomnia, hallucinations, and dream abnormalities | My daughter was prescribed Singulair at age 3. One night DH heard her talking to herself in the middle of the night for hours. When asked the next morning who she was talking to, she said, "The people in my walls." Her waking up and talking all night went on for about 6 weeks. Daughter is now 6. I mentioned giving her Tylenol for a toothache the other day, her response was, "Wait, is that the stuff that makes me see my dreams on the walls?" Connected the dots and realized that she had been hallucinating that whole time. | F | 3 | 2 months 1 tablet 1X day | 12/2/2011 | 1 | asthma | TURNED MY 3 TEAR OLD SON INTO A MONSTER,BROKEN SLEEP,NIGHTMARES,PAIN IN LEGS,AGGRESSION,STOMACH PAINS,CONSTIPATION,NOW TAKEN OF THIS DRUG AND RETURNRD TO HAPPY LITTLE CHAPPY..BEWARE OF THIS DRUG FOR CHILDREN | WE WERE ILL ADVISED BY OUR ASTHMA PRACTITIONER AND WE INTEND TO FOLLOW A COMPLAINT AGAINST AGAINST HER FOR NOT INFORMING US OF THE SIDE EFFECTS AND WARNINGS FROM U.S.A ABOUT THIS DRUG | M | 3 | 5 months 4mg 1X day | 5/5/2011 | 1 | asthma and allergies | hypersensitivity, depression, severe anxiety, irritability, muscle aches, inability to sleep. | this drug is horrible for children. if i could give it a negative rating i would. it works on the allergy and asthma symptoms, but turns my son into a completely different person. don't put your kids on it!!!! | M | 3 | 1 years | 10/24/2005 | 1 | Asthmatic cough | After one brief episode of bad couging in the fall of 2004, my son now age 3 was prescribed Singulair chewable tablets. Around late August/early September this year he began to have atonic seizures consisting of like "head drop" seizures where he would hurt his head and face and his eyes would slightly roll back - these would just last about 2 seconds max. and he would have anywhere between 5 and 24 a day. Despite the reluctancy of our son's pediatrician, we took him off the Singulair on Oct 31st as we suspect the Singulair - also, the aspartame that is in the chewable tabs of Singulair can contribute to seizures. Today he had an EEG and we are awaiting an appointment with a pediatric neurologist tomorrow. | We would encourage all parents to research this drug more closely. | M | 3 | 1 years | 12/6/2005 | 1 | Reactive Airway Disease | My son was having daytime hallucinations (hearing and visualizing monsters trying to get him), night terrors, irritability. Had same thing experienced by friends' children who said their kids were also doing the same things. BAD DRUG FOR CHILDREN!!!!! Stopped having these side effect after I discontinued singulair. | I don't think they researched this drug correctly | M | 3 | 3 months | 1/8/2006 | 1 | Chronic Cough | Restlessness Nausea Throwing Up Won't fall asleep | My daughter was prescribed singulair after being diagnosed with influenza A three weeks ago and has had a lingering chronic cough that will not leave. The first 2 nights on singulair she was not able to fall asleep due to restlessness and she was "scared of the dark." The third night she complained of her stomach hurting and puked twice (no fever) and was fine after completely emptying her stomach. I will never use this drug again! Parents please educate yourselves before giving your children such a strong medicine!!!!! | F | 3 | 3 days 4 MG 1X day | 12/29/2012 | 1 | Asthma | Major sleep disruption (early wakings, night crying), aggressive behaviour, anxiety, tummy ache, the list goes on... | We thought this would help with the chronic cough and wheezing my then 2-year-old had. It did help but, boy, did his behaviour change. At first we thought it was just the "terrible twos" and the arrival of his sister, but within 2 days of taking him off of it, he's a new little boy and one who sleeps very soundly now. I only wish I had thought a medication recommended by THREE doctors wouldn't have created such unhappiness in a sweet little boy. Giving him his inhaler a bit more often is more than worth it. | M | 3 | 11 months | 2/9/2007 | 1 | Son taking it for reactive airway | After approx. 45 days, my three-year old son became increasingly aggressive, mean, and very agitated all the time. He bit and hit and wouldn't sit still. He said he was a "bad guy". | I would NOT recommend this drug for children - particularly children who are not yet fully verbal. It took me a good 30 days to fully "see" what was happening. This is a HORRIBLE drug for children ... very disruptive to families. | M | 3 | 45 days | 4/4/2006 | 1 | Allergies / Asthma | Extreme aggressive behaviour, hitting, kicking, yelling. Turned a wonderful little boy into someone we didn't know. His preschool teachers reported having to segregate him from the other kids because of his hitting all day. Normally a very loveable and affectionate child. Always high energy but while on medication unable to shut him down. Constant night terrors, wouldn't sleep for 9 nights in a row. Out of three physicians nobody informed us of these possible side effects. After weeks of no sleep and inability to calm him down we researched it on the internet only to discover that everyone else had experienced what we were dealing with. We are kicking ourselves for letting this go on for five weeks before we asked why he was like this. We thought it was the trying three's. He complained of a sore penis as well as a "belly ache" every night within an hour of taking the medication. He cried all the time and needed constant reassurance and wanted us with him all the ti | 4mg at bedtime definitely improved his asthma and allergies. We were able to significantly reduce the need for his puffers but there is not a chance we would ever give him singulair again. He had his last dose 72 hours ago and we now have our little sweetheart back. He has his sense of humour back and loveable huggable nature. We will research everything we give him in the future before it ever touches his lips. Our family physician, the asthma clinic, and allergist immunologist are going to get an earful from us for not mentioning that these side effects were something to watch out for. Parents beware and ask questions! These little ones can't express themselves well enough yet to tell us what is really going on. | M | 3 | 7 weeks | 1/16/2007 | 1 | asthma, allergies | mood swings, irritailtiy, violent, leg pains, night terrors, depressed, senstive, drinking like crazy | My son was put on singulair when he was 15 months for very bad asthma and allergies, It worked great for him untill things started that i have just linked to the pill. I can't pin point when they started but the last year things where getting worse and then the braking point was it has been 3 months of night terrors everynight, I could not tkae it any ore and took him off, it has been 3 weeks and what a change already, Im so sorry that i waiting so long. | M | 3 | 2 years | 6/12/2005 | 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. | M | 3 | 1.5 years | 4/1/2008 | 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 | 3/13/2008 | 1 | Allergies | Tics, facial and eye swelling,lack of appetite, stomach pains, nightmares, OCD tendencies, uncontrollable screaming bouts sometimes lasting an hour | My Grandson is one of the children who has experienced these horrible side effects. In the two months that he has been taking singulair, I have watched my daughter and her husband become increasingly terrified at the changes in our happy loving little boy. I am urging each and everyone of you to contact Merck and the FDA and file a complaint in order to stop this drug from being used in children. It is one thing as an informed adult to take a medication with potential side effects, it is a totally different thing for a parent to give a medication that they have been led to "Believe" to be safe to their child. There is strength in numbers and if we all contact the news, Merck, FDA, any one we can think of and inform them about what is happening to our children on this drug, we will be able to stop other potential victims from experiencing what our families are going thru....Please I urge you to continue to spread the word about this drug - tell everyone you know. Remember, Mer | M | 3 | 2 months | 5/23/2008 |
