| 1 | asthma and allergies | aggressive behavior, nightmares, loss of appetite | My 3 year old son was on Singulair for one month before I noticed a drastic change in his personality. His behavior became very aggressive and he was unresponsive to punishment. He was not himself at all. He also complained of nightmares and experienced a loss of appetite. After finding this site, I took him off the drug immediately. He has been off of it for two weeks now and is completely back to normal - his attitude and appetite changed immediately. | M | 3 | 30 days | 12/13/2008 | 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 | 1 | Asthma, Allergies, Sinus Infections | My three year old son's behavior changed completely. He turned violent and had really bad nightmares. | He was taking 4 mlg pills. It was so bad that I discontinued it. | M | 3 | 15 days | 5/10/2005 | 1 | Asthma | 3 1/2 year old - Moody, irrational,anxious, tantrums | My 3 1/2 year old has been on this for a little over a week and suddenly stomping her foot in frustration and will not look me in the eye when I try to address anything with her. Her pre-school teacher called me today at her wits end because she could not understand what was going on with her. She would not nap, but she usually is the first asleep. She kept getting up and bothering other children. When I spoke to her she was freaking out that I was in the phone. She knows how phones work and is very intellegent, so I was very concerned. I did not give her any Singulair tonight and will never again because of the research I had done. I wish I had done it before giving it to her. | F | 3 | 7 days | 10/29/2008 | 1 | Presumed allergies, cough, wheezing | Mood swings, odd behavior, nightmares. | I only gave my son 3 doses of this medication. Two of those 3 days, he had nightmares. He was also a little more moody than usual and had behavior that was totally out of character for him. | M | 3 | 3 days | 12/2/2009 | 1 | seasonal asthmatic symptoms | nightmares, anxiety attacks, anger, change in behavior | My 3yo son started taking this 4 days ago. The first night, he had a nightmare. Starting soon after, he started hearing "sounds". We never figured out what he heard, but he'd climb the walls screaming even when he would hear you scratch. This evening he had a 2 hour anxiety attack. His personality has changed even in this short time: he's moody and angry. I wondered if it was the medication, and Google brought me here. There is now no doubt in my mind, and my child will no longer take this. | M | 3 | 4 days | 12/6/2009 | 1 | Allerty, Asthma, Congestion | Extremely emotional, uncontrollable crying, kicking, screaming, unable to calm down, back aches. | My 3yr old son was on singulair for 2 days. It cleared up his symptoms immedietley, but that is when eveything else started happening. He went to preschool and had a melt down over nothing, kicking & screaming, rolling on the floor. He could not calm down and everything seemed to agitate him more. The tantrum lasted for 90 min. and I had to come get him & bring him home. The next morning he started complaining that his back hurt, the crying started again and his teacher said he has been in a bad mood all day. This was not my son. I was so worried. The Dr. said to discontinue taking it. Now I'm wondering how long it stays in his system. | M | 3 | 2 days | 12/3/2009 | 1 | Allergies | My daughter is 3, after 1 week of taking this, she began bed wetting which she had never done, was seeing people who were not there, woke up screaming from nightmares that she said a man was trying to take her away, and worst of all last night she woke up screaming hysterically and was like this 4 hours, saying get them off spiders and other things were crawling on her and were getting her, she is. Ow scared of the dark, won't sleep. Even all day has said things were crawling on her. Scary to think our next 2 weeks may be like this paranoia schizophrenia episodes. And wonder the lasting mental scars it will leave for such a young child. | My daughter has taken Singulair for the last 2 weeks and it has helped her symptoms of allergies greatly, it does not offset the extreme side effects it caused. | F | 3 | 2 weeks 4mg 1X day | 9/25/2013 | 1 | Asthma | I definitely urge parents not to take this medicine. My daughter is 3 years old and was given this occasionally when she had asthma. Maybe like 3 times year, for a short duration of 4 days. Recently, the doctor gave her this again for 4 days. Today is the 5th day that she has withdrawn from the medicine yet it has changed her personality completely. She has become aggressive and screams that she wants to throw out her favourite teddy bear in the garbage. It's scary. As you can see no kid in the right state of mind would ever suggest this. She was not joking, she was serious about it. My worst experience are the night terrors. At first she will kick and scream about opening the door for 10 minutes, now her episodes last for 30 minutes. It is very frightening to watch. I don't know when the side effects will wear off. I miss having a sweet and happy kid. | F | 3 | 4 days 4mg | 4/10/2014 | 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 | 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 & 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 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 | 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 | 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 |
