Singulair and medications

it is so good to see this! I can't believe I am not the only one suffering with Singulair. I developed what I thought was just bronchitis, and my new doctor put me on a cocktail of respiratory meds... 2 inhalers, antibiotics, steriods, and singulair. Well, I finished the course of antibiotics, and am feeling better. I stopped using one inhaler, because it made my hands shake uncontrollably (I was assured by my doc this was normal). I stopped using the other, because I thought it was making my head feel foggy and making me moody. The only medications I am currently taking are Cymbalta for my panic disorder, and Singulair.

I have been on the Cymbalta for long enough to know that I do not suffer side effects from that (unless I miss a dose). But lately I have been more moody, emotional, snippy, and having almost daily panic attacks! I can't concentrate on a thing, my mind almost feels detached. I also suffer periods of numbness in the left side of my face.

After reading this site and everyone else's stories, I am not taking Singulair any longer! Hopefully some of these effects subside. And now I know to never let my son take it, either. I am so angry with my doctor for not warning me about these effects, not taking into consideration that I already have an anxiety disorder, and just brushing off my concerns!

hi,

My three year old son was prescribed singulair - he stopped sleeping well- and started stuttering severely. He had total meltdowns, the like of which,
i'd never seen before. We took him off the medications and the meltdowns disappeared, he started sleeping well again. The stuttering improved but he still has a mild amount of stuttering that we are treating preventatively.

My son has been taking Singular as well as Advair and Zyrtec and Nasonix for the past 6 months. He is doing so well. He has not had to go to emergency, he has not been sick, and he has not had mood swings. If you look at the prescription information that comes with Singular, you can see what the side effects can be. My recommendation is to take your child off of them if they have a side effect. I contacted my Dr. and Merck is studying only 1 case with a child that had side effects, but they did not say if this child was on other Psych medicine at the same time. The 2 psych meds that have shown a bad interaction with Singular are Phenobarbital and Rifanpin (spelling may be wrong). With all the posts I have read, very few people indicate if they are taking other medications at the same time as Singular. My suggestion is that you consult your Dr. and then send your case to Merck for more studies. If all you are doing is posting on the web, you are not solving this issue with the makers of the medication.

In response to Wewe's post, I've been wondering the same thing. Since taking my daughter off Singular almost 2 months ago, I'm seeing a different almost typical kid. Four years ago about 2 months after starting Singular my daughter was diagnosed with anxiety. As her condition got worse she was diagnosed with depression. We started to see OCD and tics so they were added as a diagnosis It was determined that it was related to strep infections so she was diagnosed with PANDAS. She was started on Zoloft and klonidine. The Zoloft made her worse. Her fears of hurting herself got so intrusive she was hospitalized. Her cholesterol was high too. The Zoloft was discontinued and Prozac was started. She's had therapy all 4 years. She also neede physical therapy due to muscle and joint pain. Now she's doing better, off Singular. Does she really have PANDAS, OCD? I don't know. She's still on Prozac, we just did a slight decrease this week. Is this medication the trigger for underlying conditions. Learned behaviors can be unlearned, but are there lasting physical effects? If a gene has been turned on, can it be turned off? I wish we knew the answers to help all of our kids.

In 2003 at the age of 31. I had been taking singulair for over 2yrs. I started experiencing muscle weakness and I got to the point I could not sit or lay down. I was extremely in a lot of pain and taking large amounts of pain medicine. It went on for several weeks. I went to the doctor because I was having muscle spams or what I thought was a ruptured disk. I had a MRI done and it didn't show anything. I was sent to a back surgeon and he checked me out and wanted me to list all my medications. I began to tell him about zyrtec and singulair. He asked me how long I had been on singulair? I told him almost 2 years. He told me to get off of it right now because it would kill me. He said the singulair was deteorating my muscles
and causing me to have muscle spasm. I had no muscle tone. He sent me to a massage therapist 3days a week for 6 weeks and I came off of the meds. The doctor told me he had at least 10 patients that had happen to them.That was a wake up call. The doctor also told me his wife was on it 6 months and started throwing up blood and took her to the ER. All because of singulair and my kids have been on it for 3 years and have not had one problem. They are 10 and 7.
My husband is a pharmacist and he had not heard anything bad about it. He filled out a card about the side effect. It only happens in 2% of people taking it.

My son, now 10...has been on singular off and on, since I don't' know how long...today was the second time he was intentionally hurting his cat. He has told me time and time again about visions while he was awake, violent ones, he argues with anyone and everyone. He has no friends at school. Last year I took him off all his medications to see why his behavior was so drastic, he got so calm, it was like a new boy, but then when he started back to public school...he had to be put back on them again, and again with the singular...
If it was not for this site..I would think my son was sick mentally. But after this...he will see his doctor tomorrow and no more singular...
When I took him off all the meds I told his doctor I was really worried about his behavior and they said it will be okay...he went right back to just out of control. Could not sleep, concentrate at school or at home. He is so smart and he is failing school..not because he is slow, but they kept saying he was add...but when I home schooled him and took him off his meds...he was so great, obdient..not perfect by no means, but just a normal boy...
I hear him right now, in the other room, fighting imaginary people...he seems to go go go..and with no sleep...the dreams in the day time I just thought were his imagination...but now that i hear about other children like him...they are to him real..just like he tells me..he also always tells me how mad he stays..he says all the time I am just angry mom, and I would say at what..he just says everything...
Thank God for this site....now i know..it is not in his head, it is just like I told his doctor...it is his medication..now I know just the one it is..
THank you all..
God Bless all the others here suffering with the same problems...it is just shocking that we as parents and patients, even after telling the doctors, are right...I feel vindicated...I will be printing this off and taking it with us to the doctors...

I just started using Singulair a few days ago. I am 54 years old and just started coughing at night only. I would be fine during the day and then never failed, at night I started to cough keeping me awake. I was given antibiotics, narcotic cough syrups but it only helped temporarily and then I went back to coughing nights only again. So as I mentioned, I started taking Singulair a few days ago because my physician thinks I have developed allergies and Singulair is noted to help night coughs. It is helping my night coughs but I still cough a few times at night and now I cough quite a few times in the day when I never use to cough in the daytime. Wondering if Singulair is worth taking as the symptoms are becoming opposite? I hate taking drugs and don't know if I should find a safer alternative? Help, anyone? Thank you

My nine year old daughter has been on Singulair for just over a month because of seasonal allergies. Early this morning she woke up with a terrible nose bleed. She has never had a nose bleed in her life before today! Could this be because of the Singulair?

Who administers this site? I posted a side effect last night after I registered and then this morning I got an email saying there was a reply to my posting and when I tried to log in, my account was inactive and my posting had been removed, as had the reply to my posting. I don't know if it is because I put a link the an online reporting tool where the FDA is compiling feedback from people/or their children who have experienced terrible side-effects. Here is the link again and I urge you all to report your cases: http://www.fda.gov/cder/drug/early_comm/montelukast.htm

My son is 3.5 and has been on Singular for 2 months and just like all of the other stories about the other young children posted here, he is a different kid after being on Singular. Last night was the first night I took him off of it. All of the side-effects that are mentioned here are the same ones my son is experiencing, nightmares (screaming in the night), hyper, aggressive, reliving injuries from days past, the day care telling me that they now have concerns about how different he has been lately and the even used the term "bad behavior". They said he is hyper, he screams, not listening, aggressive. He is a favorite at day care since he is so loving, polite and kind. I know all parents say that, but pretty much anyone who has met him compliments me on how well behaved he is. I am even nervous to have people over since he seems out of control and I have found myself ensuring people that he isn't normally like this. I have taken him off as of last night and I am hoping he will get back to his old happy-go-lucky self soon. Does anyone know how long it can take to get this poison out of their system? I pray that there are no permanent side-effects.

HI,

As with many others I found singulair to be a miracle with asthma. No more rescue inhalers. I am not sure which of my current meds is causing the very vivid, often gruesome dreaming I have been having as THREE of them show this as a side effect. I am referring to Cymbalta, Xanax and Singulair. It may be that the combination of the three is just too much and is causing brain toxicity of some sort. I started cutting down the cymbalta, and also the Xanax days ago. I found myself still waking up remembering vivid dreams that I would rather forget. I remember them all like they just happened in living color and detail, days and weeks later. At first I thought it was interesting, but now I just want to FORGET THEM, anyone have ideas???? Help!!! ( I also developed depression and anxiety after being on singulair for several years which is how I ended up with the two additional meds.

I was put on Singulair about 2 years ago because of my COPD. No allergies were ever mentioned by my Doctor. This site has been a god send for me.
Since starting Singulair I have been put on Digoxin for an irregular heart beat that I never had before. I have been put on Gabapentin for leg pain and cramping in my feet whenever I put my feet up or laid down to TRY and get to sleep. I have been put on so many pain killers for back pain, leg pain, neck pain I can't even count them all. I won't take them, they make me so sick. Now I find that I wake up with a headache every morning, feeling sick..oh yes, I was given medication for nausea also. And I don't want to forget the six months of experiencing never ending dizzy spells. That was another medication to ad to the list of ALL THE MEDICATIONS I HAVE TAKEN OVER THE PAST 2 YEARS for the side effects of Singulair. I stopped taking it a couple of days ago and I woke up this morning feeling so good. Oh, lets not forget the Xanax, Prozac and Cymbalta for depression.......OMG! I'm looking forward to see how many of these medications I can toss now that I've stopped taking Singulair. I just wish I had found this site two years ago, oh yeah, I am on Advair also. I've been, lets say "in a chronic bad mood" too. Some would say a "B". I've already noticed a difference there too.

I am not a 100% sure the experience I had was due to Singulair but it appears to be. Singulair was prescribed to me for "walking pnemonia". After a couple of days on the medications I was taking, I started experiencing pain in my knees and muscles in my lower legs. My left leg was worse than my right. After 3 days, I could barely walk and the pain was severe. I forgot to take my medicine one day and the next day my knees were much better and had less pain. I just thought I was getting better but the next day when I started the medicine again, the pain came back. I remembered when my son was on Accutane he had similar knee and leg pain because of the dryness caused by Accutane. So I kept taking the antibiotic I was on and stopped the Singulair. The next day I felt much better. On the second day I hardly had any pain at all. I was curious if anyone else had this type of side effect. Most of the postings I have seen have dealt more with depression in teenagers. I am 55.

My son, Wilson, is a bright, easy-going, athletic 12 year old who has a history of asthma and allergies. After several asthmatic episodes from age one year to about four, he was prescribed Singulair. The asthma triggers seemed to be change of season or congestion from a cold, but not from exercise or physical exertion. As I recall, his asthmatic episodes seemed to decrease after he was on 5-10 mg of Singulair, and even more so with each passing year. Over the years, of my three sons, Wilson was the one to catch any virus that came around and missed more school time than both of his brothers combined. Often, he was the only one to get sick from a virus, which never passed to anyone else in the family.
About five years ago, Wilson started complaining of stomach aches. He was tested and was prescribed Prevacid on and off since then with varying success. In the last couple of years, headaches would come and go. He was re-tested for allergies and blood work with no conclusive results. About 2-3 years ago he would complain that he “felt funny…like he needed to do something.” Further conversations revealed that he was expressing anxiety. He’s a good student, has lots of friends at school, and is popular among his sports team mates. Occasionally, a teacher here and there over the last couple of years would note that he did not participate enough in class, or did not appear to be attentive. We thought perhaps he is shy. Still his good behavior, agreeable personality and diligence otherwise earned him good grades overall. He loves school and was very unhappy having to stay home when he was sick.
This past winter, he seemed to catch a virus about once every month and a half which caused him to miss 2-3 days of school. Headaches and stomach aches were common with each illness (sometimes nausea), and sometimes these same symptoms when he was not ill. He would only complain when they were prolonged or significant. Trips to the doctor did not result in anything conclusive. Again, Wilson was only too happy once he returned to school.
He claims that sometimes in school he feels like he’s in a fog and has difficulty concentrating. He gets plenty of sleep and sometimes sleeps up to ten hours during the weekend. We attributed it to adolescence and a busy schedule. He claims that this year is the easiest for him at school, and his social life with his friends is very active. His friends’ parents like him and find him to be an agreeable child. Other adults mistake his sometime mumbling answers and lack of eye contact rude. We concluded that he is just shy. He is the most hyper of his brothers, and has difficulty sitting still and constantly exclaims that he’s bored. We chalked it up to being an active boy. His grades are good in school and we never get complaints about bad behavior.
The last illness started a week ago, and he’s still out of school. The doctor said he had no significant allergy symptoms, other bacterial infections, and his blood work all returned with normal results for white blood counts, liver and kidney functioning and anemia. He can’t return to school because of his constant headaches (which cause pain in different parts of his head), nausea, constant stomach aches, no matter what he eats, and feelings of anxiety, mostly in the evening hours. He’s also complaining of dizziness, leg cramps and other muscle soreness. The notable difference in this illness is the anxiety. My husband and I take turns staying home with him, but if we left him alone for a half an hour at a time while the other was in route picking up a sibling, he became very anxious. In the past, he seemed to enjoy some alone time at home so he could play his computer games. He also becomes easily dizzy with shooting pains in his muscles. The doctor said that viruses can manifest themselves in later stages in the form of sore muscles. However, he was concerned about Wilson’s feelings of anxiety. The anxiety had not been as prevalent in prior illnesses. I finally signed onto the internet reading all the stories about other parent’s observations of their children on Singulair. My husband cautioned me about “internet diagnosing” with symptoms and stories that can be easily taken out of context in hope of self-diagnosis. I’ve always thought that Wilson’s doctors have had good judgment. Both my primary physician and allergist don’t think that Singulair has caused these symptoms, but agreed to take him off as long as we monitored any effect on his asthma.
I don’t know what to think. I want the cause of these problems to be the Singulair, because it’s an easy answer. Today will be the first day he’s off the medication. He probably won’t go to school again tomorrow. We’ll wait and see what happens…

Sorry, I can't just walk away.

When you find patents or patent applications for certain purposes, then you know that your ideas are well founded. There are several patents for using an anti-malaria drug for asthma. I would bet that somebody had that idea all the way back to the 1960's. So it is very possibly no coincidence at all that a chloroquinoline or other quinoline ring would be part of montelukast's chemical structure.

Here is one of the patents.

******

It is well known that quinoline rings can be toxic to some people even very rapidly. As in this very extreme example.
--------------------------------------------------------------------------

PEDIATRICS Vol. 27 No. 1 January 1961, pp. 95-102 This Article

FATAL ACUTE CHLOROQUINE POISONING IN CHILDREN
Howard M. Cann M.D.1 and Henry L. Verhulst M.S.1

1 National Clearinghouse for Poison Control Centers, Accident Prevention Program, Public Health Service, U. S. Department of Health, Education, and Welfare
Four cases of acute chloroquine poisoning in children are presented. In three instances death occurred within 2 hours of ingestion of larger than therapeutic amounts of the drug. The rapid occurrence of death in acute chloroquine poisoning is probably explained by complete and rapid absorption of the drug from the gastrointestinal tract resulting in high blood concentrations which depress vasomotor function and respiration. Cardiac arrest follows and may be caused by the direct myocardial action of chloroquine, to anoxia, or to both. The similarity of the manifestations of acute chloroquine poisoning and those of acute quinine and quinidine poisoning suggests that acute toxicity may be attributed to the quinoline ring portion of these drugs.

----------------------------------------------------------------------------------

I don't think that we are seeing extreme examples. But we may be seeing less extreme immediate reactions or reactions where the toxicity builds up over time.

Quinoline rings are know to cause neurotoxicity. There are theories about how that happens. One of the theories is about blocking connexins which are gap junction proteins in the brains.

I don't know how montelukast could be breaking up so that it causes toxicity. Or if the problem is the how rapidly the liver enzymes can metabolize it. But there is plenty, plenty, plenty of clinical evidence that there is a quinoline ring culprit somewhere in the picture. Or some by-product of that causing problems.

Somehow it was decided that montelukast did not have the safety issues that the other drugs in the same category have. See this.

"The starting point in the development of montelukast appears to be a quinoline-containing structure, likely identified as a weak random screening lead (Figure 3). The Merck group hypothesized that this molecule was mimicking the olefin backbone of cysLTs, and that the addition of mimics for the acid and peptide regions of LTD4, might improve its potency. As a first step, the dithioacetal linkage first seen in some SmithKline compounds was incorporated; this led to a compound with greatly increased in vitro potency but poor oral bioavailability. When one of the carboxylic acids was replaced by an amide, forming MK-571, the new antagonist had even greater potency and good efficacy following oral administration. The enantiomers were resolved to yield MK-679 (verlukast), a compound with better clinical effects than MK-571, but whose clinical development was stopped for safety reasons. Further structure-activity relationship studies led to the development of montelukast (16), an antagonist that appears free of the safety concerns plaguing earlier members of this series."

If we can find out why the earlier versions were not safe and how they thought fixed it, then maybe we can find out what is going on with the quinoline ring in some people.

I would be very surprised if the FDA will address our concerns. Why does it always seem like they wait for enough people to die like in Vioxx? Wasn't Vioxx responsible for thousands of deaths?

Hopefully this will prove to the doubters that there are genetic reasons for the variation of efficacy and adverse side effective when taking Montelukast.

I have several areas of concern (concerned citizen is concerned). One of the main areas is the reliability of Montelukast due to differences in genetics among populations. The cysLT1 (Singulair) receptor is a GENE. As I said before, it would be possible to predict those patients for which Montelukast would and would not be effective and those patients whose gene expression profile would cause them to have unwanted side effectives.

I have been looking for a way to give reasonable proof of that which could be used to convince your doctors that Montelukast is not for everybody. I happened to locate a researcher who had invented and patented methods for predicting drug sensitivity and efficacy in inflammatory disease. I have quoted below from his patent application. He intended to provide a method for determining efficacy and drug sensitivity for pharmaceuticals which include leukotriene antagonists - Montelukast.

Quoted from:

Methods for predicting drug sensitivity in patients afflicted with an inflammatory disease
US Patent Issued on December 12, 2006

Methods are disclosed for predicting the efficacy of a drug for treating an inflammatory disease in a human patient, including: obtaining a sample of cells from the patient; obtaining a gene expression profile of the sample in the absence and presence of in vitro modulation of the cells with specific cytokines and/or mediators; and comparing the gene expression profile of the sample with a reference gene expression profile, wherein similarities between the sample expression profile and the reference expression profile predicts the efficacy of the drug for treating the inflammatory disease in the patient.

-----------------------------------------------------------
The field of pharmacogenomics measures differences in the effect of medications that are caused by genetic variations. Such differences are manifested by differences in the therapeutic effects or adverse events of drugs. For most drugs, the genetic variations that potentially characterize drug-responsive patients from non-responders remain unknown.
---------------------------------------------------------

In another embodiment, the invention is directed to a method for predicting the efficacy in a human asthma patient of leukotriene antagonists including, but not limited to, montelukast (a.k.a., SINGULAIR™; Merck, Whitehouse Station, N.J.), zafirlukast (a.k.a., ACCOLATE™, AstraZeneca, Wilmington, Del.), and zileuton (a.k.a., ZYFLO™; Abbott Laboratories, Chicago, Ill.), comprising: obtaining a sample of cells from the patient; obtaining a gene expression profile from the sample in the absence and presence of in vitro modulation of the cells with specific mediators; and comparing the gene expression profile of the sample with a reference gene expression profile, wherein similarity in expression profiles between the sample and reference profiles predicts the efficacy in the human asthmatic patient of leukotriene antagonists.

Many of the cells involved in causing airway inflammation are known to produce signaling molecules within the body called "leukotrienes." Leukotrienes are responsible for causing the contraction of the airway smooth muscle, increasing leakage of fluid from blood vessels in the lung, and further promoting inflammation by attracting other inflammatory cells into the airways. Oral anti-leukotriene medications have been introduced to fight the inflammatory response typical of allergic disease. These drugs are used in the treatment of chronic asthma. Recent data demonstrates that prescribed anti-leukotriene medications can be beneficial for many patients with asthma, however, a significant number of patients do not respond to anti-leukotriene drugs.

--------------------------------------------------

The genes selected are those that have been determined to be differentially expressed in either a disease, drug-responsiveness, or drug-sensitive cell relative to a normal cell and confer power to predict the response to the drug. By comparing tissue samples from patients with these reference expression profiles, the patient's susceptibility to a particular disease, drug-responsiveness, or drug-resistance can be determined.

Our son started taking Singulair when he was 2 for severe allergic rhinitis and cough variant asthma (in addition to Zyrtec, which didn’t control all of his symptoms). He is 5 now. For the last three years, he has been an increasingly violent, difficult, defiant, argumentative, volatile child who has intense mood swings--one minute he’s laughing uncontrollably, the next he’s weeping over nothing. His doctor and therapist recommended that we see a psychiatrist to have him evaluated for bipolar disorder, which used to be unknown in children. Because he has such chronic sleep problems, the doctor also suggested we take him off Singulair (and increase his Zyrtec dose) to see if it improved his sleep issues. Within a week, he was sleeping much better and was a calmer, happier, gentler boy. He suddenly could take “no” for an answer without flipping out and trying to hurt me. We thought that we were just in an unusual, calm window that would shift either to mania or intense sadness or both, any minute. We also thought that his behavior change might be due to sleeping better. We were enjoying the rare reprieve. Over the last weekend, his springtime allergies really flared up. We gave him Singulair on Monday and by noon, he was completely out of control. I had to strap him into his car seat at one point to keep him from hurting either me or himself. It finally occurred to me that Singulair might be causing his “bipolar” disorder. Of course, we stopped the Singulair. After two days he was a new boy. Yesterday, I Googled “Singulair bipolar children” and got a few hits. I am stunned to read how similar other families’ experiences have been to ours and I feel sick that we gave this drug to our child for three years.

Hello to everyone, I just came home from a parent teacher conference for my son who is 7 yrs. old, and heard the same old thing, "he is restless, impulsive and has a short attention span". He has been taking Singulair for about 3 yrs.. Since he has started school I have had these complaints and have also been told he displays symptoms of ADHD, which ironically has been for the last 3 years. Like any parent, I question" if I am doing something wrong with my parenting, is his diet good, etc. etc.", I am also a nurse, I realize that medications are needed and beneficial in some circumstances, however I firmly believe and was taught in nursing school that medication is last resort. That being said, I have been very adament about NOT giving my son ADHD medication after doing alot of research on the different meds and their side effects. So, we started him on all natural vitamins, changed his diet some ( kids got to have candy once in a while) and started a more structured routine( the best we can since we both work) and also enrolled him in Sylvan. The teacher says there is a 50% improvement but he is still impulsive and still does not pay attention like he "COULD", again suggesting he needs ADHD meds. I came home in tears and started to do more research online to see what else can I do besides putting him on psych meds?....Then I came accross this site, I just want to cry after reading all these posts. I wonder, could this be his problem, the Singulair?.. About a year ago he use to get up in the middle of the night, 5 out of 7 complaining of nightmares, hearing things at times, headaches, decreased appetite, stomach upset, all AT TIMES, not all the time so I never thought alot about side effects of Singulair. When the school started complaining I did look at side effects of Singulair and seen HYPERACTIVITY and mentioned it to his pediatrician and she shrugged it off saying she never heard of it being a problem. She's a great MD so I listened to her because his asthma was bad when he was younger and it is now under control. But then I think maybe he is outgrowing the asthma. I am afraid to stop Singulair and him have breathing problems again but then I can't help this strong feeling in my heart that says this may have been his problem with everything else all along. We are going to stop the Singulair tonight and see what happens. If anyone else has a child with asthma any suggestions for alternative treatment would be appreciated. I already know what's out there but sometimes it's nice to hear from another parent going through similar situs. Thanks for reading, Bobbie

It has been 18 days since my 9 year old daughter has taken Singulair. Our daughter had been taking Singulair for approximately 2 years. It was in the last year that we started to notice some behavior changes and mood swings that were so often unprovoked. We were somewhat concerned and thought like so many other parents that it was a phase. Then in December 2007 she came home from school with a tummy ache and had several episodes of vomiting. She seemed better the following day, but we took her to the pediatrician to be sure that this was a virus. The stomach pains continued, and then anxiety attacks began. Over the next month she began to wake up each day with stomach aches and we began more visits to doctors and more testing. She had abdominal X-rays, CT scan, mekel scan, GI consult and endoscopy. All were ok except she did have some small amounts of acid in her stomach. She was treated with Prevacid with really no significant changes. As weeks passed she missed more and more school, she just could not make it through the day. She had intense separation anxiety, and developed OCD about being sick again and vomiting, fears that she may stop breathing; fear of dying and the list goes on. She was refusing to ride the bus to school, and was having more and more panic attacks that would last for hours. We finally took her to a psychiatrist after we had done every test we could possibly do and all were normal. She woke up with the fear and anxiety, and fell asleep each night the same way. The doctor said she had "OCD" which she believes was triggered by the fear from vomiting. "This was the first time she had vomited since she was an infant.” She was treated with Lexapro, and Klonopin. The symptoms worsened over the next few days even with the new medications. After many calls to the doctor we were finally advised to have her admitted to a children’s psychiatric hospital for closer evaluation where higher doses of medications could be administered. She was there for 4 horrible days with slight improvements. Over the next few weeks the medication did begin to help some and she was able to make it through school each day as long as she was able to call me a few times a day for re-assurance. I thank God each day for her wonderful teacher and staff that have helped us through this. They all have known her for 3 years and knew this was just not her character at all and she was truly struggling. She was always known as "Smiley" to everyone because she always wears a grin. We began therapy with a psychologist as well and she has good and bad days. Then we heard the news about Singulair and I began to trace back other issues she had with focusing in 2nd grade and how things just seemed to progress from there. It all happened so gradually that I would never have put two & two together. She is showing improvements every day with personality, mood, attitude, fears, and the "OCD". She told me today that this was the best day ever!! I have made all the Doctor's involved aware of this information and the progress she has made in the last 2 1/2 weeks. Her doctor did cut her meds in half this week as well. Thanks to everyone that has posted their nightmares as well, and we will pray for you and for full recovery for all those that have suffered.

My husband and I have been increasingly worried about our 11 year old son lately. He had been becoming increasingly unhappy and difficult. He was in the school play, one of the things he loves most, but had no enthusiasm or energy for it. He seemed apathetic about many activities he had always been eager to participate in. I kept thinking maybe he was just tired and too stressed out. It seemed like almost nightly he was sinking into anger and depression. We were walking around on eggshells trying to prevent him from spiraling into one of his angry moods where he would just shut down and say he didn't care about anything. The happy, cooperative, well-adjusted kid we had always known was gone.

Three weeks ago we began to talk about the fact that maybe there was more going on than just adolescent angst. We were beginning to believe some kind of professional intervention might be required.

Two and a half weeks ago our local paper ran the story about the Miller family whose son committed suicide while on Singulair. My son had been taking Singulair for three months.

The same day the newspaper story ran, my son had another tough morning When I went to bed that same night, I found two “suicide” notes from my 11 year old on my pillow. (He had not seen the article.) In one he asked for a gun or knife for his birthday so he could kill himself. In the other, he told me he had been thinking about killing himself since February.

My life for the past month has been filled with conversations and appointments with the suicide hotline, the pediatrician, a psychotherapist, the school social worker, the mother of the boy who committed suicide, the FDA, etc. etc., filling out forms and writing notes and observations.

My son had just recently finished his last bottle of Singulair. I had not yet refilled the prescription, and we have no intention of doing that. The turn around in my son has been extraordinary. My incredibly exuberant and joyful son is back. I did not realize until the past few days how much light he brings to this house and how far away he had faded. But everyday, as the drug leaves his body, his beautiful, loving, affectionate, helpful happy self returns. We just kept thinking for so long… I guess this is normal for a 6th grader. It must be adolescence. It is an incredible gift to see the cloud lifting.

I worry a great deal about the children who are not as severly affected - whose parents are thinking, as we did, maybe this is just typical for kids this age. I am incredibly grateful that my son was finally able to articulate some of the horrible feelings he had inside, and that the article appeared when it did to give us some clue as to what we were really dealing with.

My daughter took singulair for a number of years because she was asthmatic and the doctor recommended that she takes one each a day. At 13 she started acting differently and I thought it was just growing up and being a rebellious teenager. I later found track mark on her arms and she was hospitalized under suicide watch. She was not allowed in school until she had numerous therapy sessions. On top of everything she was giving topamax to control her anxiety and depression and now missed so much school that she has graduate a year later.

Oh my gosh, I am just shocked after reading these posts. I am taking my son off of Singulair immediatedly!!!! I knew I wasn't crazy!! My son was on Singulair for over 2 years and it was awful. He was so hyper and uncontrollable. He couldn't control his temper. He had headaches everyday. He was put on it due to severe allergies and asthma. He is on other medications as well as allergy shots. I kept telling the doctor that I think the singulair was causing his bad behavior problems. He was just so hard to handle. He couldn't sit still for anything. The teacher couldn't get him to sit still in his chair. It just wasn't normal behavior for him. The teacher even thought he had ADD!! I didn't accept that however. The doctor just thought I was crazy and told me that Singulair wouldn't cause those symptoms. She said it actually would work opposit that and cause him to be sleepy. Well I took him off of it anyways and he did get pretty sick. His asthma acted up ect. But he eventually felt better and his behavior improved drastically. He wasn't so hyper and he could actually sleep at night and wasn't so scared at night. Just within the last week he has been pretty sick due to allergy season, his asthma has been bad and the doctor told me to put him back on the Singulair. So I did he has been on it for four days now and he is HORRIBLE.. It was an instant change. My husband and I can't control him and he can't sleep at night and has headaches every day. I am so glad I found this sight. I am taking him off immediately.
Thank you all so much for your comments. This medicine should be outlawed. I don't care what the doctors say. By the way my son is 9 years old. I certainly had no idea that it has caused suicide. I am so sorry to you all that have experienced such horrible things. Come to think of it my son used to say he hated himself all of the time when he was on this medicine.
God Bless You All

Previously posted 8 year old son w/ suicidal ideation and depression...I'm seeing comments about "inattentive." I've been saying my son is ADD for years....How many of you saw this possible side effect? Off of Singulair for 14 days now....behavior unbelievably improved.

I am starting a new post in the hopes that others will see what I am trying to say about the delayed reaction in those that took Singulair for allergies.

If it is consistent that Singulair does not stop allergy symptoms immediately, then the pathways that eventually stop allergy symptoms involve a change in the mast cell function, development and migration (or some combination).

I asked this question for a reason. Are allergy symptoms stopped immediatedly. My question below:

I have a question that will help me continuing looking for information. I can understand that in the case of asthma that Singulair would provide immediate relief. If it is used for seasonal allergies or other allergies without asthma, does it work right away or does it take a period of days or weeks to be effective? If it takes time, could you tell me how long it took in your situation?

My thinking was going in the right direction if the answer below is consistent of everyone or most.

My granddaughter was put on Singulair for allergy symptoms without asthma. Itching, red eyes, terrible congestion, etc. dark circles under her eyes all the time. When we first put her on this, we didn't see any consistent results for 2-3 weeks, then it seemed to 'kick in.' I don't know if this helps. By the way, she was 9, now she's almost 12 and was immediately taken off when this story came out 2 weeks ago.

Then after seeing one response, I gave my reason for asking.

I asked this question because I have a theory of how montelukast really works for allergies as compared to how it works for asthma.

Asthma is a hyper-sensitive state that gets going because the mast cell has a receptor (the leukotriene receptor that Singulair blocks) that sends a signal along a pathway that causes lung tissue to have that extreme response - the wheezing, the airway constriction.

On the mast cell is another receptor the histamine receptor that causes the secretions that make our noses runs and and stuff up. This is not the same immune response as the asthma response. When I saw a post that somebody's doctor said that Singulair is an anti-histamine, NO it is NOT.

So if Singulair does not block histamine immediately and your child's allergies did not go away immediately, then maybe Singulair is working through some other means such as changing normal mast cell homeostasis.
I know that this seems like "what does this mean?" I am really writing this hoping to God that there are people reading this site that know what I am talking about.

Thank you so much for responding. Your answer actually told me what I wanted to know and confirmed my hypothesis. More answers will help. I hope others respond.

PLEASE respond about the length of time that allergies disappeared if you took Singulair for allergies.

Both of my children are taking Singulair. My seven year old son has been on the drug for 3-4 years and we've noticed no problems. However, I am becoming very concerned about our three year old daughter. She was put on Singulair in November/December 2007 along with the other allergy medicines that she was already taking: Nasonex, Rynatan and Zyrtec. However, our allergist took her off the Rynatan and Zyrtec in mid-March and replaced them with Singulair. Since then, the child will not go to bed as she has in the past. She tosses and turns for an hour or hour an a half EVERY night. I've considered that maybe she needs to do away with the afternoon nap BUT she is still restless even if she hasn't had a nap that day. She is also doesn't want to get up in the mornings. We practically drag her out of the bed. This is very unlike her. She used to wake up easily every morning with a smile on her face and ready to go. Now she's a grump throughout the day and cries easily. My husband and I have decided to take her off the Singulair and see what happens. We already know that she is sensitive to some medications. We had an experience with Levalbuterol and Pulmicort (nebulizer treatments) in February that was scary. The pediatrician wanted her on the treatments 2X a day for 6 wks. The child was out of her mind on these meds. If someone had videotaped her and covered her face, I would not have know that it was my child. These meds. changed her entire personality. She took the treatments for 4-5 days and we decided enough was enough. As soon as we stopped the meds. she was back to her old self. She WILL NOT take them again unless there is absolutely no other alternative. I've decided that I've got to be more vigilant about watching for possible side effects of medications.

My son is 8 and he has been on singulair for at least three years, maybe four. When I heard about the side effects a few weeks ago, I stopped his medication right away. I have since learned that it should be tapered off, but won't put him back on to do that. He had so many of the depression, I hate myself, everybody hates me, facial tic, stomach ache symptoms . . . Now he is almost two weeks off of singulair and he is throwing screaming fits, kicking, threatening, uncontrollable for up to two hours and more! Is this a side effect of coming off of the medication? Has anyone else had this experience? Please email me at amy-weaver4@sbcglobal.net - I'd really like to hear if anyone else has experienced these symptoms. Thank you! Amy

This is the beginning of day four with no Singulair. I can still breathe, but I switched from one puff of Advair per day to two. I decided to look Advair up as well and was dismayed to find similar negative experiences with THAT drug. Hopefully for me eliminating one is enough, because I know that I need something to be able to breathe. So far yesterday was the best day emotionally, I felt a sense of calm several times throughout the day, and didn't need to be occupied with busywork to distract myself from my own thoughts. I don't have stomach pains anymore, which like most of the other symptoms I never attributed to Singulair, my head and heart just feel much "lighter" if that makes any sense. I don't feel sad, or anxious, or suicidal. I feel like I have some focus back, not completely, but a lot more than last week! I also feel like I am better equipped to handle upsetting information instead of feeling overwhelmingly sad about everything. I had my boyfriend read some of these posts yesterday, because he has been trying to accomodate my behavior for a while now, and he pointed out not only some of the obvious side effects, but there was a post about hand and joint pain, and I was constantly asking him rub my hands. I hope that sharing will help others if they are feeling anything similar, and if it's possible to stop Singulair and still breathe okay that they should try it. It is a synthetic chemical and none of us really know exactly what the short-term and long-term effects of any of these medications really are. I mean, Thalidomide was great for pregnant women who suffered from morning sickness in the '50's. Vioxx I'm sure helped many people with painful arthritis. It's only later do we find out the negatives to taking these drugs. I hate that illegal drugs are so very frowned upon in this society but "medicine" from your "doctor"is okay. Doctors nowadays I think are overwhelmed with their caseload and they read the same pamphlets that are handled out to us, laypeople, and recommend these pills to us. Drug company representatives spend a trememdous amount of money on free lunches and mugs and mouse pads and of course, if it's passed by the FDA it must be a-ok! so why not? Many patients come in ASKING for a particular drug because it is advertised on TV!!! Hard alcohol and cigarette commercials are banned, right? So how it is ok to peddle pills to us? I so many times wanted to ask my doctor about Lunesta because I couldn't sleep, and Cymbalta because "depression hurts everywhere AND everyone" and I was in so much psychological and physical pain but something told me that I didn't want to keep adding to the list, I wanted to be healthy enough someday to take some medications away! So I suffered with insomnia and debilitating depression hoping someday I could get better on my own. I wonder how many other people out there on medications who have complete faith in our healthcare system are doing more harm to themselves than good?

In response to Concernedcitizen with regard to the additional medications prescribed, we never got that far, but we were close. My son, as I've mentioned on here before (sorry for the repetition, but I think it's important), was about to be diagnosed as bipolar, which would no doubt have led to a whole host of other drugs.

Also, I totally agree with concernedcitizen with regard to not necessarily blaming our doctors. We should expect them to listen to us and take our concerns seriously, though. My son's first pediatricians were dismissive and condescending. We switched doctors and when I handed the new doctors a printout of all the posts from this site (back in 2005), they looked skeptical, but guess what? They READ it. And, my son's primary pediatrician has since told me that he's taken several kids off Singulair based on our story and the posts he read. The research provided her by concernedcitizen is INVALUABLE. If enough doctors see this stuff they'll start to question it and at least look at some of these children differently. Rather than throwing a prescription for Ritalin at them or stuffing them full of wellbutrin/abilify/lithium/klonopin/cymbalta/ they might think, "Hey, this kid's on Singulair...maybe we should try taking him/her off for a while to see what happens."

Finally, I wanted to put it out there that while kids may show mild side effects in the beginning (so mild that they can be dismissed in one way or another) I, personally, believe that with this drug side effects intensify over a period of time. My son, for example, was highly functional on singulair in the beginning and it completely eradicated his asthma and allergy symptoms, so it was great. Over time the side effects were more numerous and increasingly intense. Finally it got to the point where we couldn't dismiss it as bad behavior anymore, it was just completely outrageous behavior and my instinct told me it HAD to be the singulair. So these case studies that look at kids over a 24 week period are useless. In 24 weeks my son was fine. 52 weeks? Totally different child.

Definitely use the info provided on here, it will help not only your child, but other children as well.

Is anyone else interested in how many other medications that children or adults who took Singulair started taking after they were prescribed Singulair? If so, would you mind posting what the medication was and what kind of doctor prescribed them?

Concernedcitizen, I REALLY appreciate the hard work you've done looking for how montelukast affects the brain. I think you're making an important point here. Everything we put in our bodies affects other parts of our bodies and I think these research companies forget that sometimes. You can't fundamentally alter a bodily function and expect the rest of the body to ignore it.

The scariest thing to me is that rather than removing the antagonist (in this case, Singulair), doctors will prescribe yet another drug. So many of these children are on a multitude of medications. What a mess.
---------------------------------------------------------------------------------------------------------------
"We have no indication that anything about the mechanism of Singulair is consistent with these events (OH REALLY, YOU MEAN THAT YOU CANNOT FIND ANYTHING AT ALL THAT IS POSSIBLY CONSISTENT???)," said George Philip, director of research and product development, according to AP. "But because suicide is a life-threatening event we thought it was important to provide this information in the product label."

In a statement released by Merck, they state that in their own analysis of trials of more than 11000 patients, there was no associated risk between them taking the drug and an increased risk of suicidal thoughts.

My 8 yr. old daughter has been on Singulair for the last year (only in the Spring and Fall when her allergies/asthma are triggered by environmental factors). She started having huge personality changes when we restarted the meds at the end of Feb. The changes continued to get worse to the point that I was beside myself with worry. Saw the news report on Singulair and took her off of it last week and went to the dr. on Monday. He says that it may take up to 3 weeks to have the effect of the drug out of her system, but I am already seeing huge changes...She is back to being the wonderful, happy go lucky girl she has always been. The anxiety has just left her...She was worried about things that have never happened like being left at school or karate and about my office catching fire and me not being able to get out...

Please if you have any doubt as to what is happening with your child, talk to the doctor about it...I can't believe the trauma my child has gone through and that fixing it was as simple as stopping her medications!

My 9 yo daughter has been off and on Singulair for several years trying to get her athsma and allergies regulated. She has been put on zyrtec, and claritin and it has been a constant battle with her. She has been in and out of children's mental health facilities 3 times in the past year and has been diagnosed as having ODD (Oppositional Defiance Disorder), Mood Disorder, Depression, Severe ADHD, Bi-Polar as well as ADO (Adjustment Disorder) and emotional disorder, just to name some of the diagnosis she has had. SHE IS ONLY NINE YEARS OLD. Due to ALL these other diagnosis, she has been on and off so many different medications that I cannot help but wonder if some of these diagnosis are due to her taking the Singulair. When she was taking the SINGULAIR, she could not sleep at night, she complained about her stomach hurting all the time, she was very angry, emotional, and cried very easily for no reason at all. I have not given her any SINGULAIR since I first heard about all this stuff two days ago and can already see a difference. The fact that these people are doing this to our children infuriates me and something needs to be done!!!!!!!!

Our son was put on several medications 9/07 due to bad asthma and allergies. Since then we saw his behavior begin to go down hill. He would complain of stomaches, not want to go to school, became increasingly more irritable and has mood swings. He was a good student and we have never had a problem with him attending school. Since 9/07 we have taken him to a total of 10 different doctors. Pediatricians, therapist, allergy doctor and three licensed psychiatrists. Everyone said that we were crazy when we suggested that this behavior was linked to the medication. The psychiatrist diagnosed him with anxiety disorder along with school phobia. This has been a nightmare. I finally took him to an acupuncture doctor as a last resort because the doctors wanted us to put him on Prozac for the anxiety. Our family doctor has even suggested he is Bipolar! The acupuncture doctor has recommended a diet change and some treatments with her so that we can remove him from all his medications. I am so glad that I listened to my instincts and did not put him on the Prozac. I was so upset when this story aired about the Singulair. We have been trying to get the doctors to listen to us since 9/07 about the possible link. They still deny the connection and advised us to not remove him from the medicine. But for once I am going to handle things my way and we have already seen a difference in his behavior. We will keep our fingers crossed and hope for the best. My heart goes out to everyone that has had similiar experiences. These doctors should listen to the parents instead of assuming we are all trying to blame behavior problems on medication.

My grandson was put on singulair when he was 2 years old due to severe asthma. He fell out a 2 story window at 2 years old. His behavior became more and more aggressive as time went on. At 3 years old, he rode his bike toward a car and said he wanted to know what it feels like to be dead. At 4 years old he tried to plug a broken cord into an out let to see if he could get electricuted and die. He has obviously been to counceling and diagnosed with ADHD and on more medication for that.
Let me add that his father was shot and killed, and his mother was incarcerated twice for over a year each time. He has lived with me since he was 8 months old. He has been through a lot in his young age, so most of it has the potential to be explained away by this.
However, if there is any chance that singulair has caused or increased any of his problems, you can bet I will take him off it to see if there is any improvement.
I'm a nurse, so I know that there are side effects with all medications, and that some people encounter the side effects and others don't. I don't think that singulair is a bad choice for everyone, in fact, it has been proven to be very effective, and as long as there are no noted side effects, or possible side effects. why would you worry. If there are questionable side effects-you certainly can't ignore them! The only true way to find out if your childs problems are due to singulair is to try to take it away-maybe only temporarily.
My instinct tells me to pull it-if there is no change in behavior with him off the medication, I'll consider putting him back on it if necessary for his asthma.

If reading these posts aren't enough for you, please look at the US version of this website. http://www.medications.com/se/singulair It's just awful!!!! My family suffered for 6 months while my son was taking Singulair. He's been off a month, and is back to his normal loving self again!!!!

My daughter who is ten has been taking singular for two years. My uncle and my mom had both told me about the recent report. I was outraged. Since I didn't see it myself, I got online to check it out. I am so pissed off. My daughter has at times seemed to be depressed, my husband and I just thought it was a phase. She was never consistently depressed, more of an up and down thing. And she was fatigued from time to time. I never made the connection to Singular. I mean seriously it's an allergy medicine. And I always read the label. Never once have I ever seen a label say " may cause depression, or suicidal thoughts." I immediately took her off of it. Her last dose was 3/27/08. I noticed a difference almost right away. With in a day or so she seemed to be happier. I am so pissed off at myself and the doctors. of course I would have no way of knowing singular could cause this. I guess as a mom I feel like I should have know. I feel horrible!! Never once have they ever said anything of these reports. The FDA will be hearing from me. They hand out the medications like candy and have no idea what it really does to people. I just PRAY that my daughter, my nephew ( who was also on it for quite some time) and all these other kids out there have no lasting side effects from this medication. God Bless you all I will be praying!

My son 10, has been on Singulair since he was 4 yrs old for Asthma and allergies. His last dose was 3/26/08. He has always been my emotional child, he is 2yrs older than this younger brother. Some of his side effects included headaches, stomaches, leg cramps, emotional breakdowns, major mood swings, crying outbursts over small situations, night sweats, lack of motivation, weight gain, ADHD, wishing he were dead and the list goes on. His younger brother has always been involved in sports but he was always too afraid he would get hurt. This medication has robbed my 10 yr old son from 6 yrs of his childhood. Since he has been off Singulair he feels motivated and looks forward to joining the football team his younger brother plays for. I look forward to meeting this new young man who for so long has been hiding behind this so called allergy medicine. I am so thankful to know that my son can look forward to a bright future without these side effects. God Bless you all who are going through this as well.

my son is 9 and has been on SINGULAIR since he was about 5 for bad asthma and allergies. he has had trouble in school since he started, we thought it was ADD. he started having constant stomach aches and headaches. we started seeing a counselor because he would say things like "I hate my life" and "I don't want to live anymore" thats when he was 6. he had many other issues like hallucinations, night terrors, bed wetting, anger problems, depression, trouble focusing at school, mood swings, emotional ups and downs, just to name a few. we have been to pediatricians and psychiatrists and no one mentioned ever that it could possibly be the singular. we have added other medications like most parents, for ADD which made him worse. about 1 year ago he was diagnosed with bi-polar and was prescribed Abilify, an anti-psychotic. he has since gotten somewhat better but I never connected the Singulair side effects to his symptoms. (note: bi-polar symptoms in children are strikingly similar to bad side effects of Singulair) maybe he doesn't even have bi-polar! maybe he was more subject to having these side effects because of underlying problems. I have stopped giving him the the Singulair a few days ago but i don't see a significant change, yet. Its a very sad thing that parents like myself have so much trust in our doctors that we give our children these medications before we know anything about them. I myself will never make that mistake again and my prayers go out to all those who have made the same mistakes.

My son was on Singulair for 4 years the start of an absolute nightmare,but never did i make the connection,i read the pamphlets i read the side affects i told my doctor,but we were hung out to dry to figure it out for ourselves,I have taken him to countless professionals,who always ask List your medications,I have cried in there offices i have begged for help.I ended up taking things into my own hands ,taking him out of school, home schooling and changing our families life to accommodate his sleeping difficulties and feelings of complete in adacy plz someone tell me this will get better, tell me this is the answer,finally when i talked to his pmd i was told to stop giving him the drug immediately

We lost our home to a house fire this past August so when my 8 year old daughter experienced severe depression, night terrors, and was constantly acting out we naturally blamed it on the house fire. The odd thing was that she had the "normal" depression immediately after the fire and started to become herself again. Several months past when she started this severe depression and horrible behavior. We brought her to a psychiatrist because this was just not the depression she was experiencing after the fire.The psychiatrist diagnosed her with post traumatic stress disorder and explained that with children it can take months for this to "come out". Well, with allergy season on us in the South, my daughter started her Singulair treatment the exact time of this recent behavior. Needless to say, we are taking her off the Singulair, I will post again to let you know if she makes a turnaround.

Posting my experience again.

You are not alone and your children are NOT hypochondriacs (something tells me small children don't even know what that means).

My 5 year old son was diagnosed with mild asthma and put on Singulair. Within a few months he began having uncontrollable fits of rage, displayed self-loathing behavior, had night terrors, and was inconsolable during these episodes. He became very destructive and was a danger to himself and our family. He even talked about killing himself and would say things like "I don't want to be in this life anymore" and "I want to kill myself". He would threaten my wife and his siblings and told them he wanted to kill them. It was a truly terrifying experience. Our pediatrician was clueless to these side affects and recommended we have our child go through a psychological evaluation. I knew this was not my child's normal behavior so I searched the internet for Singulair side effects and found some message boards where parents just like me were telling their stories of their children's aggressive behavior. I immediately took my son off the drug and within a couple weeks he was back to his normal self. He told us that he no longer has "that feeling inside of him". Five year old children don't even know what suicide is and to see my son talk like this was extremely frightening. He is a sweet, intelligent, loving boy who had never exhibited behavior like this until he went on Singulair. We have not seen this behavior after taking him off the drug. Please use your best judgment and connect the dots for yourselves.

I have been taking Singulair for at least 10 years, most of which on a daily basis. I had severe stomach pains and nausea for a period of time, went through a lot of testing and other medications all of which did not help and was at times limited to eating saltines. I also experienced anxiety attacks and depression. The depression would be on and off for periods of time. I attempted suicide several times. Only within the past 3 years, 3 years in which I was not taking my Singulair regularly (limited the Singulair to a few days at a time when I had asthma attacks or respiratory colds), was I no longer suicidal. I am not blaming these symptoms on Singulair but it is no surprise to me if it was the cause, as it was the only medication I took daily in that time period.

I like to live my life with facts, not speculation and drama. My child is on Singulair and doing fantastic. I remember the trips to the ER when I did not know if my child would live or die. Of course when I saw this report, it caused me some concern so I did some research on my own. Did you know that suicide is the leading cause of violent death in New York State, the United States and the world? In 2002 in New York State there were 1,292 suicides which exceeded homicides by 32%. The statistics show that 1 in 10 teenagers plans to commit suicide. The National Center for Health reports a 10% suicide rate in kids 15-24 years of age and 4 male suicides for every female suicide. Suicide is the third leading cause of death among those 15-24 years old.

So now we have 1 child in New York that has committed suicide that just happened to be on Singulair, and it is Singulairs fault? Show me the proof. All I see is one distraught mom who is trying to find blame for her son’s tragic death. Is there only half the story being told, a trend I have noticed in journalism these days. Let’s face it, life happens. I am NOT on Singulair and I have had melt downs, thrown things across the room, been depressed over things, cried, and even for the past week have been having some crazy dreams. I remember as a child putting notes on my room door telling my parents how much I hated them. I remember as a teenager thinking my life would be better if I were dead. I remember my child being cranky and fussy before she was on Singulair, gee maybe she was teething. The term “terrible twos” has been around a lot longer that Singulair. Let’s face it, we have turned into a society of people who always want something to blame. I think it is time people start taking responsibility for themselves and accept the fact that sometimes life just happens. Take accountability for your own lives, and stop trying to blame everything and anything.

I also live my life by reading internet blogs with a grain of salt. These blogs are public forums and places where anyone and everyone can post. How do you know that all these posts are real? Remember the day when kids made prank phone calls for fun? Now they have the internet and can post pranks on these blogs. How do you know that a competitor to Singulair is not posting in order to fuel the feeding frenzy? How about a registered sex offender or a felon in prison? There are a lot of “sick” people in the world and yes, they have access to the internet too. If you are hanging on every single one of these posts as being true and real then I feel sorry for you. The internet provides anonymity and it is easy to create a fictitious identity and a fictitious story. That is probably why if you do a search for “internet safety” you get 15,700,000 hits.

Until I see proof, I am not going to take my child off Singulair. The CDC reports that in 2002 there were 1.9 million visits to the ER for asthma and 4,261 asthma deaths. If I did stop my child’s Singulair, and she died in the ER from as asthma attack, whose head does that fall on? The media?

As a pediatrician I write for singulair every day.
The medication is for allergies.
Allergies cause adenoidal swelling, which cause sleep disturbances which makes the child tired the next day with makes him over weight, less attentive, hyper and eventually act out.
This in turn makes the child experience parental, peers and teachers criticism/ abuse, with leads to the child feel inadequate, embarrassed, frustrated and eventually depressed and suicidal.

Yes, singulair does cause behavioral change but they appear within the first couple of peels, the rest is due to allergies, lack of medical care, i.e. sleep, singulair, and zyrtec deficiency.
Allergy shots cause 4 times the incidence of suicidally than singulair, and Ritalin 10 times more.
They say in hebrew "once a stone is thrown into a well, thousands of smart people won't find it".
Check it, it's true.

I'm 17 years old, I've been taking Singulair for about 3 or 4 years now. I didn't take it all the time, just when my allergies and asthma would kick in. And I can honestly say every time I've taken it I've had mood swings out of no where, I've felt depressed, anxious, had nightmares every night I took it (I usually took it every night with the rest of my medications). It is extremely Ironic that just the day before I heard about the report of linking it to suicide, I was just telling my mother how depressed I was and how I couldn't sit still, felt anxious, wanted to rip my skin off, and I couldn't get sleep. I went to the doctor yesterday, and she told me to discontinue it and to throw the rest of it away.

I cannot believe that there is so much of ignorance in such an educated society. Let me first start by saying I am on no medication absolutely I do have bronchitis I don't take cough medications or allergy medications or inhalers etc etc. I read at the bottom in a post that this 28 year old cries every time she sees te Save the children advertisement. I can tell you I listen to music, I watch tv and every touching or heart rendering story or lyric makes me cry!!! I wonder if i was on Singulair I would certainly be committed to some mental asylum.
I think all you educated people should consider that you do not need to be on a drug or any medication to suffer from depression symptoms or any such other emotional trauma. Why blame one thing alone, blame the governments for putting its citizens under stress , blame your economies for bringing down your county into a recession where your earnings don't meet the cost of living, What we should be fighting for is irrelevant, so some strategy comes into light where all these years, read all the posts, 2 , 5, 7 10 years of using Singulair and NOW you want to complain. Why didn't they complain all these years ago and get the drug recalled.. Don't blame one thing alone. Maybe if people lived cleaner, healthier lifestyles you wont be taking medications.

After reading the recent news reports and reading other parents opinions on Singulair I thought I should be fair to the company, and to other parents seeking advice on this drug, to write about our POSITIVE experience with Singulair. Our 7 year old son was diagnosed with seasonal Asthma when he was 3. We have him on the Ventilator and Advair. During spring time allergy season he would begin wheezing and coughing on a regular basis. We would then give him his puffers. While it would relieve him of the wheezing he would be quite hyper and out of control. Therefore, our goal was to wean him off the puffers. We added Claritin to his diet each day. When he was 5 he struggled through his spring soccer season. As the months went by he looked tired, very sickly, and worn out. His coach recommended that we investigate Singulair. It really turned his child's life around! We talked to our doctor about it. She wasn't familiar with children using Singulair but she prescribed the 5mg chewable but recommended that he use both puffers before his soccer games. We followed her advice. He took his Singulair before bed and the puffers before the game. Sadly, we noticed that he was completely "out of it" during his games. He had no focus (not shocking for a 6 year old boy), no real interest in the game, and no energy. We just assumed it was because he was tired after a full day of school. One day we forgot his puffers but decided to let him play anyway. He had a great game. During a daytime tournament he was back to having his head in the clouds, so for the second game we decided to "forget" his puffers again. He played a great game. But best of all..no breathing problems. We decided to omit the puffers for the rest of the season and just use Singulair. It worked wonderful for him. None of the side effects that the other parents have described. We use it when spring begins and for the the first part of the fall season. He doesn't use it during the winter months. We are experiencing a real dry March so I started the Singulair on Tuesday. Then all of the negative comments came out. I certainly will not dismiss the concerns of the product. We are watching him closely to make sure there are no negative side effects. So far, so good. And no need for the puffers!

My daughter was prescribed singulair about six months ago when she was 4Yrs. old, after about a month on the medication she stated complaining about stomach pain, headaches, and refuses to eat. She recently started running high fevers at night and has been very emotional. The doctors only had great things to say about singulair,it makes me wonder if our childern's doctors may be getting some kind of financial incentive for prescribing these medications to our children.

My 4 year old has been on Singulair for about 6 months or so. He was put on it by his ENT Dr. because he kept getting sinus infections due to his allergies. He also takes zyrtec on the really bad days. We are seeing so many of the same symptoms I just spent the last thirty minutes reading with my jaw to the floor. As He chewed his pill tonight my husband was telling me what he had heard on the news today. I immediately got online to see what I could find. WOW! I would have never thought this could possible be the cause for the angry outbursts, the tossing and turning until 11 pm many nights, the out of control, on the floor kicking and screaming, hitting, throwing anything in his way as he stomps off to his "time out" for throwing this type of tantrum. Could the Singulair really be the culprit? In a way I almost hope this is the case, otherwise we will have to continue with our recent discussions of getting him in to see a Psychiatrist.
I graduate nursing school in 5 weeks and have learned about many types of medications and all the "common" side effects of them. I never would have put two and two together that these behaviors could have been linked to an allergy medication So, tomorrow night we start an experiment and will not give the Singulair. We'll see what happens...

5 year olds do not talk about suicide...period!!!

My child was on no other medications. I have reported this to Merck and the FDA and have also changed pediatricians after a lengthy discussion with her. I cannot speak for others.

The issues with Singulair are far from over. Stay tuned.

My daughter is 5 years old and has been on Singulair for the past 2 1/2 years for severe asthma. THANKFULLY, she has never experienced any of the side effects that your children or any of you have listed. She has never had any problems with it and we learned last year that it is something that she needs in order to keep her asthma under control. Last September, we decided to take her off the Singulair since she had not had an asthma flair up in almost a year and she was hospitalized 1 week later for a severe asthma attack. The reason why I am sharing this information is to let people know that these side effects do not happen to all of the patients that take this medicine BUT I DO AGREE THAT INFORMATION ON THESE DANGEROUS SIDE EFFECTS NEEDS TO BE SHARED WITH THE POPULATION THAT TAKES THIS MEDICATION! I want to thank everyone for sharing their stories of their experiences with this drug. I appreciate the information that I would probably never hear from a doctor or drug company, even though it is the most ETHICAL thing to do, especially when it has such a negative effect in children! Now I know what could possibly happen in my child and I will be more attentive and I know what to look for. I will be making an appointment with her doctor to see if there are other choices of medications that could keep her asthma under control and has less psychological side effects.

My daughter is 12 yrs old and has been on Singulair for about 2 yrs. on and off but since her last Dr.'s appointment and with her breathing results the Dr. told her that she NEEDS to take the SINGULAIR every day. She's been taking it now for about 5 months straight and in the passed 2 months I've noticed a change in her attitude. I, too attributed it to a "pre-teen" thing. It was kind of gradual though, one day I was talking to her and she just blew up at me, which is not like her at all, she started crying and saying that she knows I wished she was never born and so on....I was devastated, this was so shocking to me because she is such a good kid, will help anyone and her and I could always talk with each other. I couldn't believe she thought any of these things because we have such a great relationship together.
Then I noticed that she has put on at least 20-25 pounds since she's been on this and she isn't doing very well in school...I laos attributed this to "the age", she's in 7th grade and I've had numerous meetings with her teacher's who told me that it's just the grade, and how it's a big transition for 7th grader's...now I'm not so sure.
I'm afraid to take my daughter off of this because she has the lungs of a 70 yr. old person...and that scares me. I'm going to have to wait until Monday morning to call her Dr. before I take her off. We've been to the E.R. several times in the last 5 yrs for her asthma and each time has been during the middle of the night, which you would think seeing as though they aren't active at that time that the asthma wouldn't act up until during the day. So as a precaution, I need to keep her on this 2 more days to see what the Dr. says. I'm not a bad mother and if I could, I'd take her off the medication right now, I just hope there's something else they can give her that's safe. I don't want to lose my daughter!
