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)

 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.

 4  Asthma/Allergies None when on the medicine. If I take a break for even a day or two it affects my mood. I get highly aggressive, cry for no reason, and even have what I would call severe depression. It works great and helps, but I skipped a few days on purpose this last week to see if it still caused the same reaction. After two days I was scaring myself with my thoughts so I went back on it. I also take a lot of other allergy/asthma meds and this was the only variation in my routine. I have not ever have thoughts or feelings like that before, besides when I have missed doses of Singulair. I tried talking to one of my doctors about it but they just advised me not to miss a dose. Be careful when starting because if you have the same side effects you may not ever get to stop. M 23 3 years

 3  allergies slight drowsiness, dry mouth, dried out sinuses similar to what a cold or flu medication will produce Was as effective as Zyrtec and Chlor-Trimeton, but not as effective as Claritin in clearing out my sinuses. Singulair doesn't work well enough for me to deal with the minor side effects, especially when there are other drugs (Zyrtec and Chlor-Trimeton)that have no side effects for me. F 25 1 days

 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

 1  Asthma- cat allergy Night terrors, screaming up to 40 times a day, hitting, aggression, hyperactivity, insomnia, lack of attention span, where previously there was a great one. I only figured this out a few days ago. She is also on Advair inhaler daily. I've even changed her diet. I'm so glad to see that these medicines may be the cause of behavior that is soooo terrible, that we've had to isolate from family members. F 4 8 months

 3  asthma depression, extreme anxiety, suicidal thoughts, rage, rash, leg pain, tingling/burning under skin I just recently went off of this drug. I thought that maybe it could be causing my extreme anxiety. After reading this, it appears that I was right. I have been off of it for only 2 weeks. I feel calmer than I have in a long time. Even husband commented that I sound different. Not sure what to do about meds. Dr wants me to try symbicort. Very hesitant to try something else. Have had issues with other inhaled steriods. Must be better alternative. F 48 2 years

 1  asthma aggressiveness,tantrums,nightmares,hearing voices,ADHD behavior My six year old son has been on Singulair for almost one year. It has worked for his asthma but we have seen a sweet happy little boy turn into a monster! The changes did not happen right away but slowly. After his dosage was increased when he turned six things have escalated. He has been a crazy child since starting kindergarten. He is now in the care of a child psychologist, child psychiatrist and a team at his school. He has been suspended for his behavior and kicked out of his after school program. He started meds for ADHD 3 weeks ago with little improvement in his behavior. Like many other parents I have asked the doctors can it be the Singulair and they all say oh no way! After talking with a pharmacist who told me of the horrible side effects - which by the way are not listed on the drug companies web site - I have chosen to stop the Singulair. I pray that it is the cause and that I will get by sweet loving little boy back. Something should be done about this and everyone should complain LOUDLY to the drug company! If it turns out that our world has been turned upside down by this and hundreds of dollars spent on our son's mental health issues someone sure will hear from me!!!!!!!!! M 6 11 months

 1  Allergies Seperation anxiety, uncontrolled crying, general anxiety My 7 year old has been taking drug on and off since she has been 2. She has suffered on and off from bouts of crying, unexplained fears and SEVERE seperation anxiety that started out of nowhere. We were never able to pinpoint a reason until reading experiences of others. I mentioned this to her doctor when it all began and the idea of this med causing anxiety was dismissed. I feel so guilty for not checking into this sooner, and especially for not persuing it further. She asks way too many questions about death, dying and cemetaries and we could never figure out why. She cries when happy, sad, scared for just about anything at all. Always intermittently, never consistently. When you ask her why, all she can say is I can't help it. We could never figure what the trigger would be, now I have finally have a place to start. She is off the med for 10 days now, and hopefully it will work it's way out of her system sooner rather than later. F 7 4.5 years

 1  asthma frustrated, unable to concentrate, teacher and family noticed a definite change in personality and performance, frustration lead to verbally expressing wanting to "kill myself" This is about my very intelligent, sensitive 8 yr old nephew. This scared our whole family. THE BEST WAY TO BRING ATTENTION TO THESE ADVERSE EVENTS IS TO REPORT THEM TO THE DRUG MAKER MERCK AT 800-444-2080 AND THE FDA AT http://www.fda.gov/medwatch. THIS WILL HELP BRING ABOUT AWARENESS AND CHANGE. M 8 3 weeks

 1  coughing related to asthma severe nightmares,aching legs Please do not give this to your children! My confident child turned into a clingy, insecure little girl within 3 days. She had "bad nightmares, mommy" and said they were really bad and she didn't want to talk about it. My little girl normally describes everything in detail. She also had aches in her legs. F 4 3 days
