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)

 5  Coughing/allergy symptoms Mild increase in agitation/agressiveness. I want to encourage other parents not to be afraid to try this medication. It may have negative side effects for some children, but you won't know if it helps unless you try it. My son has been taking it in fall/winter over 2yrs. It is very helpful for his coughing at night and allows him to sleep. We saw very mild increases in agressive behavior, but nothing we can't live with for the moment. I think this medication can affect different kids differently. M 3 2 years

 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

 3  Eczema, allergic rhinitis I believe the med has helped the eczema symptoms, but the side effects are not worth the relief. I have noticed increased irritability and moodiness in my 6 year old daughter. It seems to be worse in the morning and evening. She seems fine at school, but with her sisters she is looking for a fight. She is the baby of the family and somewhat spoiled. This is still not normal behavior. We are stopping the med tonight. I hope we see results soon. If not, let the punishment begin! F 6 30 days

 3  Asthma/ Allergies Bed wetting, moodiness, depression, crying, leg pain, making clicking noises in his throat. I have four sons all of which have breathing issues. My 7 year old, 5 year old and 4 year old are on singulair. After reading everything posted on this cite I now have a new insight into my two middle children. My oldest has been on singulair since he was 3 and has no problems with it in the 4 years he has been taking it. When the doctor recommended that my two other boys take it I figured no problem. I was wrong and they will be stopping it tonight. My five year old is wetting the bed, crying all the time, acts depressed and has dark circles under his eyes. My four year old is a completely different child. He screams all the time, has no respect for anyone, is constantly fighting with his brothers and has complained of his legs hurting. He was the sweetest child I had. I used to joke and say he was my angel from God because his older two brothers were driving me crazy. I could not figure out what happened to him. He is fine at school and as soon as he gets home he is a different child. We are now discontinuing this medication for two of our boys. For now my oldest will stay on it because he has severe asthma and it helps him. M 5 6 months

 3  Allergies My son had extreme mood swings, behavorial problems at shcool, agression, aggitation and bad dreams. The side effect lessoned a couple of days after stopping the medicine. The side effect is gone now and it has been two weeks since he has stopped taking singular. I have taken Singular for a couple of years with no problem. I was shocked when my 8 year old son started acting differently - I would have never guessed it was the singular. But his mood is totally back to normal after stopping the medicine. M 8 4 months

 3  Asthma Bed wetting, excessive talking, night waking, nightmares, aggression toward the dogs, hyperactivity. My son can just barely stay out of trouble as it is. Sometimes we have to go back on the singulair so that he will stop coughing and wheezing. When we do, we see his behavior get much worse. It takes a couple of weeks to really start working and about the same time the coughing stops, the talking starts. He will jabber out loud so fast my husband puts in ear plugs. We have to weigh the asthma symptoms to the amount of trouble he is causing. My son has been on and off this drug for 4 years. When he takes it he stops coughing and wheezing it works really well. It is good and bad. M 6 4 years

 1  Congestion from allergies uncontrolled urination & bowel movements; nightmares, inattentativeness at school; moodiness; slight aggressiveness; sleep walking My six year old son was on the medication for about three weeks before the abrupt changes in his personality. The first indicator was a phone call from his teacher very concerned with the unexplained "accidents" he was having at school. This was very unlike my son considering that he never had any type of "accidents" since he was potty trained at two years old. My son's teacher also described my son's inability to concentrate and almost an unwillingness to do his work. The potty "accidents" continued at home with almost a daily occurence. I began noticing a change in his level of moodiness and aggression. Unhappy with a conversation I was having about him with his grandfather, my son hit me with a plastic toy bat. What was alarming was the action, not necessarily the force. The straw that broke the camels back was when he was caught sleep walking. He ended up in my kitchen, removed his shorts and underpants and urinated on my dining room chair and kitchen floor. He was completely unaware of the incident when he woke up later that morning. It wasn't until I connected these changes to the onset of putting my son on this medication. I passed along my concerns to his pediatrician who merely dismissed it as a change in his diet and now having a sleep walker on our hands. Her advise was to bulk up his diet and to put gates and bells around the house to awaken us if my son continued to sleep walk. I know my son, and I know his behavior patt M 6 1 months

 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

 2  asthma/allergies outbursts, argumentative, anger, depression, hyperactivity, expressed suicidal ideation. My 9 year old son began taking when he was 6. His teacher thought he was ADHD. Last year, I began to think it also. We ran out of the medication and i took two weeks to refill it. The second week he had a really good week at school. The next week he was back to being a problem. I remembered reading about side effects but never made the connection until then. I have since stopped giving it to him and the negative behaviors are dissapating. I am angry with myself for taking so lomg to see the connection. He is at his 3rd school in 3 years because of problem behavior that could have been avoided! M 9 3 years

 1  Allergy Induced Asthma Night terrors, hallucinations, anger, depression, violence, suicidal thoughts/comments, extreme mood swings, crying, moodiness. I had no idea these were side effects. I don't remember reading any of these when we started the Rx. My friend told me about her son and his experiences, which were exactly like my son's. We are done with Singulair. M 11 2 years

 1  Asthma My son has been taking Singulair for a year and a half. Initially, I didn't notice any changes, but over the past several months, he had developed a habit cough and has gradually taken on strange eye tics. Kids have started noticing at school. He also seems to be a little on edge and not the happy go lucky kid I know. I took him for his annual pediatrician appointment to discuss the tics and he suggested I look at the Singular that the allergist had prescribed. I am taking him off it immediately and I feel that this drug is a horrible poison. I feel terrible for not making the connection sooner, but better late than never, I suppose. M 10 1.5 years

 1  asthma allerigies depression,anxiety,sleep disorder,school phobia,ocd while my son was on this drug,my family and my child went through hell,this drug is poison for some.It is so important that anyone who has experianced the rath of this drug make a report to the fda,this is the only way someone may listen.The doctors sure do not seem to recognise the havoc this drug causes,if they did they would not brush off us parents,send our children to therapy and give more drugs to combat the side effects of this benign pretty pink pill that is killing children M 11 3.5 days

 1  asthma aggression, extreme agitation, irritable, tantrums and depression This med was prescribed to my son when he was 3 years old however it wasn't until he was 4 that he took 4mg daily then 3 months prior to his 6th birthday is when the dose was increased to 5mg...which is when all hell broke loose. Last week when I found this sight I cried. All this time it was the singulair and not one doctor attributed my sons change in behavior to this horrible drug. Now that we have stopped it some of the aggression, depression, agitation, and tantrums are improving...I hope with time we get our son back completely and that the terrible side effects we have experienced go away. My poor son is only 6 years old and has been thru hell because of this med. I am sure many patients do fine on this medication but it isn't for everyone. I just wish I realized the link sooner.

 1  Allergies Anger, yelling, frusration, disrespectful communication with family, exhaustion, lack of patience, trantrums, problems listening I originally asked my 7 year old's primary care physician for recommendations for sleep issues with my son. My son has always been a perfectionist and easy to anger, but he has a sensitive heart and always wants to please. I thought his initial problems were due to sleep problems we had seen with his inability to sleep through the night. He had chronic nasal conjestion. He was put on Singular. I was so happy with the results. He no longer had the 24/7 goopy nose. BUT 1 year later, I have an 8 year old that can not control his temper, we feel like we can no longer talk to him withour him going into a trantrum. We have gotten to the point that we feel like we are yelling at him all the time and he responds unreasonably to us or anyone. It was not until my neighbor took her son off singulair and said she notice he calmed done, that I began to tie the Singular to my somes worsening problem. I had just scheduled a meeting with his physician to talk about possible behavioral problems when I googled 'Singulair" side effects and found this page. I am so releived. I hope this will give us back our son and help him to gain control of his emotions. I know he is a smart, caring son in side this poor child. I am taking him off this drug immediately! M 8 1 years

 1  allergies teeth grinding, aggression, not listening, mood swings, tantrums, complete melt downs and unable to calm down for up to 20 mins. hitting, biting My 2 year old son has been on this medication for 90 days and experienced all of the side effects listed. At 1st we thought maybe its just the terrible 2's everyone keeps talking about, so we did more research on behavior/discipline, but quickly realized this was way beyond a phase and was only getting worse. We finally made the connection to the medication and took him off it. Too little too late though, he was ultimately kicked out of daycare because of his aggression. He has been off of the meds for 3 weeks now and we are going through the "detox" phase. Things are better, but I am wondering how long this will be in his system and how long these horrible side effects will last. I just want my sweet little boy back!! M 2 90 days

 5  asthma My 8 year old son has been on this medication for 3 years and there have been NO side affects. His behavior is the same he does not have nightmares. All I have noticed is he does not cough excessivley and that is a major plus in my book. I was checking this website cause he has gained weight but he has always been chubby even as a baby. Probably nothing to do with the medication. I would recommend this medication to anyone. M 8 3 years
