Singulair and drugs

It has been interesting for me to read this posts. I have been wondering about the long term side affects to singulair- mostly because my 11 year old has been on Singulair for several years now. We spent many of nights in the ER for asthma when he was little and no Dr. did testing. When he was 5 his pediatrician tested him for allergies and put him on Singulair. We have had a great experience with it. I find it interesting that many of the health issues on here- joint pains, bouts of depression, weight gain...I personally experience all of them and i am not on any medication. My 11 year old does not experience any of the mentioned side affects. I wanted to find out long term side affects for my own personal knowledge. Prior to Singulair, he was on Zyrtec which was not a good fit.

I am looking for any information anyone has about the possibility that Singulair causes colitis or that it can lead to inflamed colon and bleeding colon. My daughter is 4 years old and has never been a sick child. In September, she started bleeding from her colon, and a month later, she was finally diagnosed with colitis after having a colonoscopy. The doctor prescribed Prednisone (steriod) and Phlagyll (antibiotic) (spelling?). I decided to stop giving her the Singulair that she had previously been taking because I didn;t want her to have so many drugs in her system as one time. After a few days of the steriods and antibiotics, she was well, with no signs of problems. Everything was going great for a few weeks, but last week I started giving her the Singulair again, and her colits symptoms have come back. Has anyone else experienced this in relation to Singulair?

My 10 yr old son has been on this medication for 3 months - it helped his symptoms right away. Just in the past week we had a couple days without it when we ran out. He started back up again and has had bad nightmares twice this week and told me that he doesn't sleep well at night. My question is - are their other drugs out there that work as well as this one that do NOT have these side affects? Zyrtec just made him tired.

My daughter was put on Singulair 2 weeks ago after discovering she is allergic to 4 kinds of trees that are pollinating in the fall and a certain mold that grows in corn and bean fields. Everything was going well until she got an ear infection and was put on the antibiotic amoxicillin which she has used off and on when she's had ear infections over the years. She then broke out in the hives. She has never had the hives before. I'm guessing it could be a combination of the two drugs. Why aren't doctors aware of this before prescribing this medication?

I visited (accidentally) this web site a little over a year ago...it was a total blessing and, I feel, a life saver!!! Our grandson Trevor was totally out of control and talking about killing people and himself at the age of 4 yrs old.
One phone call away from calling a therapist, I saw this and we took him off the Singulair immediately. He has been 1000 times better and not depressed anymore. This is a totally true story and I'm so glad to spread the word. T***'s Grandma

I am 44 years old and have been taking singulair for about 4 years. 3 months ago I started experiencing crushing chest pain, tingling in my lower limbs, and felt very stressed out. I went to the ER last Thursday and was checked out for angina - the ER doctor told me I was suffering from chronic severe anxiety. I took Ativan for 4 days and felt better, but now the drigs are gone and I again having constant chest pain. In doing some research I found that anxiety can be caused by imbalance in adrenaline, and so started looking online to see if any of the allergy/asthma meds I am taking (adviar, singulair, allegra) can affect adrenaline. That';s when I found this website. Although i find the testimony compelling, I wish more folks would have poted about how their symptoms improved (or didn't) AFTER discontinuing singulair. Also I've noticed many of the stories are about children not adults; many people are taking more than one med for asthma, and most people's symptoms seem to come on right away whereas I have been taking sinulair for years and only recently have anxiety. I will stop singulair tonight and see what happens, but am wondering if anyone has come across further research that correlates singiulair with anxiety? My job life is really peaceful, I am otherwise happy, work can get hectic but that's true of any job, and I am out of ideas as to why suddenly at age 44, when I eat right and exercise - why get anxiety? Thanks for the posts, I'll try to remember to follow up after I am off Singulair for a few weeks.

I am a 36 year old woman, and I have taken Singulair for the past 8 months. I got a lung infection over the winter, and the clinic I went to put me on the 10mg Singulair. It helped my lungs and got me over the worst of the infection, but I never anticipated the side-effects. For several months, I attributed what I was feeling to hormones (like severe PMS) and the stress in my life. I started to have thoughts of death, especially at night. I also began to have a hard time leaving my house. I would have panic attacks, worrying that the window was left open, the stove was left on, and god forbid there was a dark cloud in the sky (I became convinced that a terrible storm would come). Several times, I nearly got in a car accident racing to get home after work. Then, I started to obsess over getting sick. I was convinced that I would get some terrible disease and die soon. The fears and anxiety got worse and worse until one day (a rainy day), I quit my job of twelve years. It was a good job. I was happy with my work, and I made more than enough money. I ended up moving across the country back in with my estranged husband, because here I would not have to work. I could stay home all the time, away from germs and storms and anything else bad. That was three months ago. Still on the Singulair, I began to obsess over death. The panic attacks were so severe that they triggered asthma attacks, and not being able to breathe triggered more anxiety. I stopped sleeping at night. In three months, I've slept four nights. I began to have nightmares that made me wake up screaming and violently lashing out. I had to urinate 5 or 6 times every night. I developed severe stomach pain and nausea. And I had leg pain (actually, I hurt everywhere, severe pain). I had headaches, dizziness, and fatigue. Slowly, I began to realize that it might be the medicine. I started to research, and yesterday, I took my last pill. Since then, I have not had one panic attack. I have not had one asthma attack. I slept last night with no bad dreams. I know what's happened now, and I'm so sad that I lost so much of my life because of this drug. I really had a good life...friends, a home, a great job... Now, I'm very tired. My body is very weak and still hurting. I'm shaky. But I believe in time, those effects, too, will go away. I feel like my body has been through a war. I'm grateful that I didn't kill myself. There were a couple of really bad days when the urge to be violent towards myself was overwhelming. One day, I punched a fence, making my knuckles bleed. I think I could've killed myself, and I know it was Singulair. It's going to be better now. Just as a note: what helped me withdraw without any major worsening of asthma was Advair 250/50 twice a day.

My eldest son was diagnosed as a Severe Asthmatic at the age of 3. He was put on Flovent 110, 5mg of Zyrtec and Singulair. I cried thinking about my little guy having to be on daily meds for who knows how long. I decided that I would just try the Zyrtec and Flovent 110, it worked wonderfully. When my eldest was 4, my other son, 2, was put on Flovent 44. Never gave them to my youngest because I knew it was not asthma. I ended up lowering my eldest's dose to the 44 and giving him 1 puff a day with the Zyrtec, he is now 7 and is still under control. As for my younger son, he was not asthmatic, he had sleep apnea, had his tonsils and adenoids removed and is now perfect. Just be careful with these doctors, they seem to diagnose these little ones too quickly......most of the time they are not even right. My eldest went through many many doctors before he was finally diagnosed in the ER and sent to peds for 2 weeks. My youngest went through many doctors too, none would do anything, I had so many excuses as to why my son was such a heavy breather and why he had difficulty swallowing and sleeping. Sorry guys, I ran off here, just want you guys to know that all that are diagnosed with asthma do not necessarily have asthma and I believe way too many drugs are prescribed for these little ones.

My son has been on singulair for 4 months now to control his asthma. It has done wonders in doing what it was intended to do, however, he's experiencing all of the side effects that the other parents are listing on this site. I threw his singulair in the trash a few nights ago after my son had a complete emotional melt down; which I could easily see he had absolutely no control over. I knew the drugs were changing his personality a bit, but I thought it was just the price we had to pay to keep him out of the hospital. My gut told me never to give him the meds because I had heard about the suicidal tendencies associated with the drug, I just knew I had to watch my son closely (plus he's only 3). I have 3 boys, and the one with asthma is my mild mannered, never gets in trouble, as close to perfect as a child can be. He's been saying "poop" and "pee" uncontrollably along with aggressive behavior toward his brothers and he would cry for no reason at all. His sleep patterns had changed as well, which I now know are due to nightmares - I even found him hiding under his bed a couple of times. I do not know why this drug is approved for children, but after reading the other stories I realize this seems to be the standard instead of the exception. I hope they pull this drug off the market before any more kids get hurt. I feel like I have poisoned my child - I will definitely be spreading the word on this. Anxiously awaiting for this medicine to leave my sons body so I can have my sweet little boy back.

From the FDA's "Updated Information on Leukotriene Inhibitors: Montelukast (marketed as Singulair), Zafirlukast (marketed as Accolate), and Zileuton (marketed as Zyflo and Zyflo CR)"

6/12/2009

Neuropsychiatric events have been reported in some patients taking montelukast (Singulair), zafirlukast (Accolate), and zileuton (Zyflo and Zyflo CR). FDA has requested that manufacturers include a precaution in the drug prescribing information (drug labeling).

Montelukast is used to treat asthma, and the symptoms of allergic rhinitis (sneezing, stuffy nose, runny nose, itching of the nose), and to prevent exercise-induced asthma. Zafirlukast and zileuton are used to treat asthma.

The reported neuropsychiatric events include postmarket cases of agitation, aggression, anxiousness, dream abnormalities and hallucinations, depression, insomnia, irritability, restlessness, suicidal thinking and behavior (including suicide), and tremor.

This information reflects FDA’s current analysis of available data concerning this drug.

Advice to patients and healthcare professionals:

Patients and healthcare professionals should be aware of the potential for neuropsychiatric events with these medications.

Patients should talk with their healthcare providers if these events occur.

Healthcare professionals should consider discontinuing these medications if patients develop neuropsychiatric symptoms.

Background

In April 2009, FDA completed its review of neuropsychiatric events, (mood and behavioral changes) possibly related to drugs that act through the leukotriene pathway (montelukast, zafirlukast, zileuton). As part of its review, FDA reviewed post-marketing reports and also requested that manufacturers submit all available clinical trial data for these products.

The post-market reports of patients on these medications included cases of neuropsychiatric events. Some reports included clinical details consistent with a drug-induced effect. In the clinical trial data submitted by manufacturers, neuropsychiatric events were not commonly observed. However, the available data were limited because the trials were not designed to look for neuropsychiatric events. Sleep disorders (primarily insomnia) were reported more frequently with all three products compared to placebo.

Started Singulair 5/14/09. Within last week or so started having extreme pain in shoulders, hands (especially thumbs), wrists and hips. Put ti down to arthritis. Pain has been getting worse every day. Thought it was a food allergy so stopped eating fruit and have cut out all sugar. Yesterday realized that pain has increased so it wasn't the food. It suddenly dawned on me that it could be the Singulair. Stopped taking it last night and am already much better. Still some pain but not so excruciating.

About a month before my Dr. gave me Advair. After a few days on it, I went to bed and thought I was having a heart attack. Pain across my back and down my arms, up my neck and across my chest. This happened 2 nights in a row and decided to stop taking it. Called my MD and he said to stop it immediately. However, he thought it really might be my heart so I had an echo cardiogram and stress test. They said my heart was perfect. After 2 days off the med had no more trouble..

My take is that these "air" drugs are not for me. My MD is on vacation and won't be back until Wed. I will speak with him then. Hopefully by then all paij will be gone. Will post again to report results of stopping Singulair. Reading all these posts also made me realize my depression, irritability and crying has probably been a result of this drug.

By: Fed Up

Has anyone been in contact with any doctors, hospitals, or researchers who are willing to recognize that Singulair targets a receptor CysLT1, with known genetic variations? As you know, I have been posting that I know of researchers who are doing work about how the genetic variations can determine the efficacy of Singulair. If genetic variations cause differences in efficacy, then, of course, these variations can also cause unpleasant to very serious side effects. These seems to be some kind of disconnect. How can the genetic component be recognized in the area of efficacy and ignored in the area of adverse drug reactions?

I just wanted to post an update.

I took my son off singulair over a year ago. He was on since he was 2 yrs old and had started with chronic headaches at about 10 yrs old. He also had tantrums(I don't know how else to describe it), was upset and sad and basically disliked himself. He cried all the time. I had always thought it was just him. These symptom had come on slowly over the years.

The first week off this med, it was like he was freaking out and everything was 100x worse. But the headaches almost immediately disappeared.

Other parents were wondering how long it took for his personality to change.or if the kids would remain that way.

It took quite a long time. It was worse for weeks after we took him off. Then it slowly started to improve.

In the last 6-8 months, it's like living with a different child. There's no crying, he's happy, there's no tantrums anymore. Gets a headache maybe once a month instead of daily.

He still has allergies, he still has asthma. But for the first time in years he seems normal. I love that word, normal.

I have been on Singulair longer than I can recall... at least 10 years, maybe longer. My 7 year old son has been on it since he was probably 12 months old. Neither one of us have had any problem reported here. No depression, no sleeplessness (until I weaned him from naps, he slept up to 13 hours a day), no leg cramps, nothing. We are two of the happiest, most well adjusted people you could know. And, best of all, we haven't had any asthma attacks. Bottom line, different drugs react differently in different people. Don't let the post here stop you from trying a medication that for some could mean the difference between life and death depending on how asthmatic they are. As with any drug recommended by your doctor, try it. If you experience adverse reactions, stop it ASAP. It's that simple.

well, well, well, I stopped taking Singulair about a month ago after reading bad side effects. Guess what? My medication resistant depression is GONE. I was on Singulair for about 9 yrs....and on EVERY antidepressant there is....I went thru so much ag, and side effects, when it was the Singulair all along! Now to find a NATURAL asthma helper.

i took Singulair for one week. The first couple days, I had a head ache, sore throat, cough, and some other upper respiratory issues. I started to feel better, but I had to stay home from work and rest. About 5 days later, I took my singulair in the morning (I missed the night before). About 2 hours later I was sent home from work early due to nausea/diarrhea. I was in bed sick all of that day. I skipped the singulair that night and the next morning, and took it the following night. Again, 2 hours later I has severe diarrhea. I have been off Singulair for a day and a half and my diarrhea is gone. It is so weird, the whole 3 days I was off work, and calling out- I felt so depressed, like I did not want to go back to work, I was dreading it! BUT i love my job, and I have never felt like that before. I am really worried this medicine is what made me sick! I would not give this to anyone, and especially reading the things about what it does in children, I definitely believe this could happen!

My seven year old son has been on Singulair for a year and half. He would get angry but he's a kid...and I didn't think anything of it. Then the headaches and bad dreams....and then he's always talking about death. One day, I wasn't home when he arrived from school and he met me at the door crying....he thought I was dead. But the muscles cramps really got me. He's to young for cramps and waking up with a charley horse. I took him to the clinic and to the ER twice.. and still the doctors don't know why he's getting muscle cramps. So I said...let me go online to find some answers. Well... you know I'm going to his doctor and I threw his bottle of Singulair away. I'm going to start a journal and chart his progress and I'll get back to y'all.

I'm 43. Started taking Singular about 10 years ago. I think that's when it came out. Over time, I've developed panic attacks, mild depression, mood swings, panic disorder, muscle twitches and cramps, and agoraphobia. I finally slowly took myself off of all medications after doing The Allergy and Asthma Cure - a great book and it helps tremendously!

After being off of the Singular, my symptoms listed started going away. i stay have agoraphobia because that's a learned issue from fear of having a panic attack. All doctors and pharmacists say there's no link. I know lots of adults who have gone through this only to get put on Xanax and antidepressants. Try to go as natural as you can. All of these meds have fried my body. Diet is huge to! I've substituted goat's milk for cow, Try it!

To people like chris555, I believe you are engaging people for sport and say very hurtful things,your day will come and it may just be in the unemployment line.I can only imagine that you must work for Merck or you would not feel so threatened by the good that has come from Parents advocating for their childrens safety.I want you to know, that all who knew our family and our child understand what took place and our reasons for trying to get the proper information where it should have been," on the label". When our child died no one knew about all the added side effects from post marketing reports,which is "a reliable way to track a drugs adverse events".Maybe you should do more research on the legitimate information of causal relationship. Don't be so afraid of a possible drop in revenue for the drug company that I believe you might be an employee of.K. M.

I am 34 years old. I am a pharmacy tech. I have asthma and allergies. I have taken singulair pretty much every day since it came out on the market. I've had asthma since i was about 10 years old. I took theophylline as a kid. Steriods on and off especially during times when my allergies are bad. I still use Advair during the fall and spring. Every drug has a side effect. However breathing is pretty good damn thing. Do I have days when I feel low? Yeah. Do I sometimes have nightmares? Yup. Are "natural" products the answer. Not always. The fish oil that some of the posters are touting can also cause GI problems. Some of the natural products contain herbs and other plant derivatives that can be harmful for a child that suffers from allergies. Not proactively treating asthma can be deadly. Some of the parents are suggesting steriods as the answer - those can cause weight gain, growth suppression and can lead to a worsening of asthma.

Singulair has never made me feel like I've wanted to kill myself. I was more depressed and angry as kid when my asthma did not allow me to partipate in normal childhood things. I was sad and hated life when I couldn't keep up with friends at recces because I was having trouble breathing. You have to outweigh the costs with the benefits. I am more irritable when I have asthma flareup then I am on a normal day. For me, I choose to breathe. And singulair has been helping me for almost a decade.

I'm not saying the medication isn't causing these symptoms but maybe there is an underlying cause to your child's depression.

Any drug has a side effect. But without medical research and the medications that come with them - people would still be dying of simple diseases and we wouldn't have vaccinations. As a society, as a whole, we are a culture that looks to someone else to fix things and then blames the people who try to fix it. We need to stop being the "hot McDonald's coffee'" society.

I'm so happy that I decided to research this drug. My son, who will be 2 on 1/22/09 was prescribed Singulair today. He has been coughing/wheezing, etc since we moved to a different state, 6 months ago. We have tried all kinds of OTC drugs and nothing would work. We finally brought him to the Dr. today and he says he has allergies (which we kinda knew already). I was happy that the Dr. prescribed something that we could not get OTC..to me, that meant that it was going to be better. I went to pick up the prescription and the pharmacist tried to talk me into a different kind of allergy med for my son. I told her that I wanted to stick with the Singulair, since that is what the Dr. prescribed. She told me, in no uncertain terms, to research this drug! She kept asking, "He's only 2, right?" He's only 2, right?" Her behavior was strange, I thought....it turns out that she was my angel today. I gave my son 1 dosage tonight before bed and he WILL NOT get another. Thank you! On Monday, my first order of business is to go back to the pharmacy and thank my angel....

My 9 year old son started Singulair 5mg about 8 months ago. Shortly after, he started to occasionally complain of stomach pain and not being hungry. About 2 months ago, they changed the dosage to 10mg. He now has chronic diarrhea and severe weight loss. We stopped the medicine about 2 weeks ago, but he's not "back to normal" yet. He's never had any digestive problems before. The doctor's recommending endoscopes, and we're at our wit's end.

I had been taking singulair for over two years. I am 70 yrs old and in good health except for light asthma, allergy problems. My doctor took me off it. It did some good in the beginning but the last four mts I was continuing to get wheezing and bronchitis infections. I also had a lot of leg pain and was tested for all kinds of blockage, etc. I experienced very painful leg cramping, toes twitching, etc. The only way I could stop it was to pull my toes forward as the worst happened at night and woke me up. I finally found Leg Cramps with Quinine an all natural homeopathic med. It worked like a charm. I didn't know that this was a side effect of Singulair. Since I am off singulair just two weeks. It was replaced with Flovent an inhaler ( 2 puffs 2 x a day to begin and then later it will be 1 puff as the inflammation gets better. It also comes in granules. I am feeling much better and now I am ready to stop Leg Cramps as I feel the singulair may have been causing the problem. While taking Singulair I also had stomach cramps with diarrhea. I will not go back on Singulair. If the cramping returns, I will definitely go back on Leg Cramps with Quinine (available in any pharmacy over the counter and very inexpensive.

So happy to find this site. I never noticed My son never had an eye tick until last month, ironically we started giving him Singular on a daily basis about the same time. My son just turned two and is has also been waking up screaming 3 times every night. Have others reported this same problem...also he is on Pulmicort too, have you read that it is linked to Glaucoma and Cataracts? Do you think that this could be causing the tick? Please HELP! I want a parent's opinion before bringing this up to the doctor...they are so quick to jump to more drugs it makes me sick! Thank you! Any other children with eye "ticks" like really quick consecutive blinks?

Why does Singulair cause these symptoms? I am going to give my explanation which is only a HYPOTHESIS. This should not be categorized as any thing but an educated guess. This is not backed by scientific research because nobody will do any research that would appear to anger
Merck even if people are suffering in the thousands.

1. The original research that preceded the development of Singulair (montelukast) seemed to focus on the theory that asthma was caused by an unusual immune response to certain pathological stimulus. There are many references to the observation that a high percentage of asthma sufferers are people whose asthma is caused by fungus. Many people suffer from asthma and are told that they are allergic to dust mites. Dust mites can live only because the fungus aspergillus pre-digests the
food source that dust mites can then absorb. Other sources of fungus occur in the home due to dampness or problems with wood rot.

2. The body's immune system fights certain categories of pathogens such as bacteria and fungus by creating nitric oxide which kills them at the site where they try to enter the body. The mast cell is the immune cell that is responsible for the production of nitric oxide. Mast cells are found in the skin, airways, intestines etc. The mast cell is capable of many different types of biochemical functions that are designed to signal other cells or other chemical responses. When the mast cell knows that pathogens
are present and nitric oxide is NOT produced, then it signals other immune cells to be sent to the site of the infection. Thus in the case of asthma, it is known that excessive numbers of eosinophils appear in the airways and these cells create inflammation.

3. Singulair was developed for asthma and later allowed to be prescribed for other reasons. I believe that montelukast probably creates a source of nitric oxide that prevents the mast cell from signalling for other immune cells to arrive at the source of infection. I arrived at that conclusion from studying the chemical structure of montelukast, the chemical structure of the gene cysLT1 receptor, and the chemical structure of the cell wall of fungus which would be what the mast cell uses to determine "what to do in order to kill the fungus."

The researchers who invented montelukast first had to clone the gene-cysLT1 receptor meaning that they had to be able to identify the gene and replicate it. Then by trial and error they had a find a "chemical"
that would bind (connect chemically) to the cysLT1 receptor. The theory would be that montelukast would take the place of the fungus or other pathogen and thus prevent the gene from reacting to produce the
responses that the sick patient with asthma produced. Merck says in the literature that montelukast binds with the cysLT1 receptor in order to prevent the mast cell from signalling the eosinophils to arrive in excessive
numbers that cause inflammation. I believe that montelukast is also causing the production of an amount of nitric oxide that is actually killing the pathogens that are present. For one thing, I would think that it
would be dangerous to incapacitate the immune system in that way without providing a way to kill the pathogens. I don't believe that the asthma response is just allergies to something like dust. Pollen from trees and flowers is loaded with fungus spores.

4. IF, IF, IF, montelukast does actually produce nitric oxide, then it does so by binding with the gene. Any place in the body where a molecule of montelukast encounters the cysLT1 receptor (a gene) then the corresponding molecules of nitric oxide are produced before the liver enzymes break the montelukast molecules up. Nitric oxide is TOXIC and
INFLAMMATORY. So let's look at the symptoms in regard to the location of the cysLT1 receptors. The location of these symptoms would not be places in the body where the mast cells normally encounter fungus or bacteria. The cysLT1 also has other functions in that it communicates with the cysLT2 receptors. Obviously, nitric oxide
should not be produced in these locations because of the signalling effect of nitric oxide on other physiological functions.

a. intestinal pain - the cysLT1 receptors are located in the small intestines
b. leg pain actually caused by vasculitis - cysLT1 receptors are found inside blood vessels- consistent with the fact that montelukast causes
Churg-Strauss
c. some people who didn't have asthma develop asthma - the cysLT1 receptors are in the airways
d. nightmares, depression, neurological damage - when montelukast penetrates the blood brain barrier probably due to unusual conditions of blood pH or electrolyte imbalance then nitric oxide in the brain causes neuron damage and excitoxicity

5. Why do some patients not experience side effects? Probably because genetically they are completely compatible with the model that researchers created when they cloned the cysLT1 receptor gene. I didn't not find any information about whether researchers knew that there are many different variations of this gene.

6. IF, my theory is even close to being correct, then why doesn't Merck do anything about researching these side effects. Maybe because nobody in the company knows how this drug works but the researchers who created it. All of the Merck literature is very vague about any biochemical information.

Again, this is just speculation and hypothesis. I have made an attempt to put this in simplistic language and therefore sacrifice scientific accuracy. But, I think that you will get the point.

SINGULAIR IS VERY DANGEROUS TO PATIENTS WHO EXPERIENCE NEGATIVE SIDE EFFECTS. DOCTORS SHOULD JUST REALIZE THAT
THOSE PATIENTS ARE NOT COMPATIBLE WITH THE MODEL FOR THE DRUG.

My 5 1/2 year old son began taking 4mg Singulair in the p.m. and an inhaler (asmanex) in the a.m. We were still having trouble controlling the asthma and his Sing dose was raised to 5mg. & within 1 week of the increase he began having terrible facial tics and aggravated behavior (defiant, poor listening, easily frustrated and angered) The tics were in the form of opening and closing his mouth, as if you were trying to clear your clogged ears after a plane flight. This caused him much pain in his jaws and facial muscles, so he would tic and then cry as he was in pain. This ramped up his anxiety and it made the ticking worse. He has been off of all asthma medication (cold turkey) for 5 full days. He has episodes where the tics happen for 10 min -1/2 hr, other times during the day it is one here and one there. He does not want to leave the house to do anything, even his favorite activities. Thank god I found this site (and others like it), as I got some answers and some hope. We went to see my cousin this week who is a neurologist and he never heard of the correlation of Singulair and neurologic side effects like these. He said that (hopefully) the medication side effects will cycle through and resolve the ticking and behavioral changes. If not we are probably looking at a Tic Disorder which is in the Tourettes Family.He put my son on a very low dose of Klonopin to mellow out his anxiety and help reduce the tics, but has only been on it for 1 1/2 days and it usually takes a wk or 2 for full absorption and results.I have since sent him and my pediatrician and allergist links to this site and others. I think that I see some improvement in my son, yesterday I thought he did better and my husband thought it was a worse day, I think we have totally lost our perspective and objectivity on this. If anyone out there has a time frame on when they saw significant recovery and positive changes I would love to hear from you. This is a total nightmare and if it is this drug, someone is going to pay. My prayers go out to all who are going thru this.

My son is almost 5 now and has severe food and inhalant allergies, along with sever asthma. When he was 3 he was hospitalized for 4 days because of his asthma. I have been warned that only 1% of asthmatics will ever be hospitalized, so I've made sure he stays on all his meds. He has been on Singular ever since he was 15 months old. At first it was a God send. Everyday was a constant challenged, fussy, icthy red eyes, constant flow of mucous and wheezing. I would have to pin him down 6 times a day with the inhaler, but when Singular came "poof" it was like magic. He was on Singular when he was hospitalized and is now on 3 meds; Zrytec, Singular and Q-var all given to him everyday. Lately we have had some major issues come up for him. I think I have the next J. D. living with me. NO FOR REAL. My next step is a shrink. You might think I'm mean for saying it, but I don't know how else to describe it. When I was driving he asked for some gum, because I wouldn't let him pick out his own piece, he got out of his car seat and started hitting me over and over again, pulled my hair and tried to "break my arm" as he put it. I had to pull over and I couldn't get him to calm down he kept slapping me in the face and kicking me not only was I embarrassed, but it hurt, I was crying. I have finally come here trying to see if other children, who are on Singular, have had similar episodes. He is a very good boy most of the time and aggression is a hit and miss. I don't know what to do.

MY APOLOGIES TO ALL FOR AN ERROR IN MY PRIOR POST. WHEN I CUT AND PASTED THE INFORMATION FROM MERCK'S WEBSITE NOT ALL OF IT APPEARED IN MY POST FOR SOME REASON. THE CORRECTED INFORMATION IS BELOW. CHECK THEIR WEBSITE FOR YOURSELVES TO VERIFY THIS.

THIS IS FROM THE PATIENT INFORMATION:

"What are the possible side effects of SINGULAIR?

The side effects of SINGULAIR are usually mild, and generally did not cause patients to stop taking their medicine. The side effects in patients treated with SINGULAIR were similar in type and frequency to side
effects in patients who were given a placebo (a pill containing no medicine).
The most common side effects with SINGULAIR include:
• stomach pain
• stomach or intestinal upset
• heartburn
• tiredness
• fever
• stuffy nose
• cough
• flu
• upper respiratory infection
• dizziness
• headache
• rash

Less common side effects that have happened with SINGULAIR include:
• increased bleeding tendency
• allergic reactions
• behavior and mood related changes
• drowsiness, pins and needles/numbness, seizures (convulsions or fits)
• palpitations
• nose bleed
• diarrhea, indigestion, inflammation of the pancreas, nausea, vomiting
• hepatitis
• bruising
• joint pain, muscle aches and muscle cramps
• swelling

Rarely, asthmatic patients taking SINGULAIR have experienced Rarely, asthmatic patients taking SINGULAIR have experienced a condition that includes certain symptoms that do not go away or that get worse. These occur usually, but not always, in patients who were taking steroid pills by mouth for asthma and those steroids were being slowly lowered or stopped.
Although SINGULAIR has not been shown to cause this condition, you must tell your doctor right away if you get one or more of these symptoms:
• a feeling of pins and needles or numbness of arms or legs
• a flu-like illness
• rash
• severe inflammation (pain and swelling) of the sinuses (sinusitis)
These are not all the possible side effects of SINGULAIR. For more information ask your doctor or pharmacist.
Talk to your doctor if you think you have side effects from taking SINGULAIR."

My daughter was prescribed Singulair in the spring and it worked wonders.Since her allergies and asthma don't bother her in the summer I took her off for those few months.Since she has been back on the last few months I notice once and awhile an aggression/depression behavior.I thought immediately that it was Singulair causing this but it wasn't everyday it happened.I believe that activity,schedule,and even food in combination with this medicine that was cause this rare effect.It's no news to parents that all of these things can change a persons attitude and behavior.I also believe that Singulair may just make people more sensitive to their true self as my daughter has always been paranoid and has lacked self esteem.I think that it is trial and error as with any medicine.Try it and it may or may not work for you.Taking it off the market would be a disgrace as it has saved many lives.

Just wanted to offer a follow-up on our daughters behavior since getting off Singulair and Advair. AMAZING difference. She is a pretty normal 12 year old now. The most noticable thing to me is her voice. On the drugs she always sounded so gruff and angry. Now she sounds sweet. She smiles so much more and is not eager to become angry. I can reason with her more now when there is a disagreement. It will be a long process to break habits of behavior that have developed over the past ten years, (yes, ten years, she started these poisons when she was two years old) We are very hopeful for her future. I am so very thankful that I was led to this site.

What you will not hear elsewhere: Though Singulair is likely safe, it is ridiculously over prescribed. Singulair is indicated for the treatment of allergies and asthma. For allergies, It has not been shown to be more effective than Claritin (which is now generic and over-the-counter). In fact, when Merck-Schering were trying to add Singulair to Claritin, they found it no more effective than Claritin alone (sound familiar?). In this case, they decided not to manufacture this new pill. The most effective agents for allergic rhinitis are inhaled nasal corticosteroids. Flonase is now available as generic fluticasone, and is much more effective then Singulair (which is not generic), Claritin or the combination of the two. Regarding asthma, the updated 2007 NIH guidelines recommend inhaled corticosteroids for asthmatics of all ages. The data is overwhelming, clear and convincing. Singulair, which has much less of an effect is considered alternative therapy by the NIH. Yet, Singulair remains one of the most commonly prescribed drugs for asthma.

I am a loving mother of a 5 1/2 year old boy. He has been on Singulair for over 3 years. In this past 3 years my son has suffered in an unspeakable amount. He came down with Rota Virus and was hospitalized at 2. He then came in contact with Pneumonia in the hospital while he was there. They automatically put him on Singulair, Zyrtec, Prednisone, and antibiotics to treat the pneumonia. Since that day, my son has gone though more tests than I have in my entire life. He has had asthma, sinusitis, leg cramping ( to the point he cannot walk for 2 years), IBS, Acid reflux,(they gave him laxatives for a year that made things worse and addicted to them also), stomach pain, constipation and diarrhea back and forth. He also got Erythema Mulitforme TWICE, while on this drug. All of which the doctors said could NOT be caused by Singulair. He has had several Upper GI's and CT scans. Along with Barium enemas, several hundreds of blood tests, and many many pokes and prodded that were not necessary. All since he has been on Singulair. He now has frequent bathroom trips, depression, confusion, and anger outbursts. He also has to go to the restroom every 5 minutes. He has had genital swelling, and many other aches and pains. None of which his "doctor" ever said could be a result of Singulair. I am 100% sure it was!!!! He currently has anxiety and emotional sporadic issues causing problems in school The teachers and counselors say that it is so strange because there is no TRIGGER and the outbursts are completely inconsistent. His preschool teacher and director are sure he has ADHD. Well, we had him tested and he does not have any part of it. He has no learning disability what-so-ever. So that brought me back to square one. He is in a positive loving enviroment. How could he be depressed and want to hurt everyone around him? He cannot sit still. He cries and says he is 'stupid" and "can't think" like the other boys. He has nightmares and cannot sleep alone. He is scared of everyone and everything. So, as I sit here crying, I realized that this has all been a reaction of his "medicine" Singulair. He never should have gone through all of those painful tests, only to prove they couldn't find anything. So many treatments and sound full advice speeches from his doctors. How could they be so naive and selfish in the life of my son?

When I called my pediatrician of 5 years, she told me that " parents that have children with behavioral problems will LOOK for something to blame their problems on." She also said "drug companies only put side effects on their labels to PROTECT the drug companies. (as she laughed at me) They are not always valid". Then she said "if you take you child off of Singulair you will be playing Russian Roulette in his life." Then she said that all children around 5 or 6 go though this emotional time in their lives." She told me that if I take my child off of Singulair that she would no longer be a part of his health regimen for his asthma. She told me to see a Pulmonologist for further treatment.
Who is paying who? This is my son's life???????? I decided to go with my mother-gut instinct and get him off of this medicine. No matter what. He has been a different person since. He is currently going though a lot of side effects and withdrawals (leg pain, insomnia, hic-ups, emotional distress) but every day is getting better. How can the drug companies say that this is a "wonder drug?" There are more reported side effected patients then clinical studied patients! How can a "medication" that stimulates the brain not be connected to other problems? This "medication" interferes with the bio synthesis and action of LTs and has been marketed as NOVEL medication against asthma and allergic rhinitis. Who the hell is playing God here??? The pocket books of Merck or our over PAID "doctors?" Who pays the price? Our children? Or us. Thank god I found this before it was too late. I would not be able to withstand the pain of losing my son due to their lack of scientific evidence. They are lucky I am one of the smart ones. I will not settle for less than Justice for the drug companies and their paid "doctors?" You all end up in the same place. HELL

There are 18 million people on this drug. Most of them are children. Please save a life if not your own child's life. Thank You

I have been reading a book on anxiety and phobias,it says that the Gene # 23 is shorter for people pre dispositioned for anxiety,If this is the case it makes sense as this drug works genetically,,so i wonder the % of short 23 to long 23, and that would give Merck its % of adverse side effects...betting its more than they are saying.As far as the doctors still saying this is a small %,they are just not asking the right questions,The insurance companies should have a record on clients that filled prescriptions for singulair and anti depressants and adhd drugs.If we all cn figure it out in a week ,Well what does that say

My daughter had been on singulair from the time she was 8 yrs old until she was 14. This will sound as if I am a horrible mother but I just thought that she was a raging bitch. Without my knowledge, she stopped taking her Singulair for a few months and she became a different person. She was so sweet and loving. One night she came in my room having an asthma attack and I asked her if she was taking her meds, she admitted that she had stopped taking her singulair and I got on to her and immediately got her prescription refilled. Within a few days of taking the singulair she turned into a raging, screaming emotional wreck, a TOTALLY different person. I feel so bad that for 6 years of her life I put her on medicine that caused her to have screaming, uncontrollable tantrums, and severe mood swings that caused her to be miserable. It does seem to be the only thing that effectively controls her asthma symptoms but the emotional havoc that is causes her and the people around her is not worth the benefits. We have an appt. with her doctor to see what other options we have.

Hi Everyone,
WBZTV out of Boston interviewed my family this evening about our singulair experience. They seemed very interested in this story as it relates to how families and individuals have been affected by singulair and will be airing it soon....don't know the exact date yet. My son was able to say on camera that it made him feel "crazy" inside when he was taking singulair and that he feels "much better" since he stopped taking it. We told them we feel lucky to have gotten through our experience but there are so many others who have suffered and are currently suffering very badly as a result of the side effects of singulair.
I think the FDA and Merck now need to stand up and start taking some accountability for a drug that is admittedly "over prescribed". Doctors should be divulging the potential side effects of ALL drugs BEFORE prescribing it so the patient can be fully aware. I mean c'mon the warnings are on page 28 of a 33 page patient information pamphlet. Don't you think it should be on page 1? OK, maybe page 2.
They need to black box this drug. People have lost their lives to it and doctor's need to take their fingers out of their ears!

Hey to All.
I know that the ALA study got everyone upset and I am happy we all emailed her.We all pretty much got the same response from Heather,defending the study and the integrity of the results.If only this investigation would conclude!
The Merck company contacted our Senator and indicated there was a conclusion and then ,they never got back to her before the weekend.I will have news early in the week.Please everyone just keep on voicing your concerns by reaching out any way you can.Sometimes it seems unbearable and I have to take a break with the communications on this website but,I continue my communication with my local contacts and the FDA.
I would love quick results and everyone would love this to get the publicity this story deserves but,if you look at how far we have come getting attention focused on this drug it is amazing.
This website has been here for years and people have complained and nothing has been accomplished until now.Our system is so broken it will take time to fix it.Drugs get approved everyday and when they are put out for multi use,the population benefit -risk ratio changes and there is little oversight on this matter.
The problem is much bigger than just notification of updated side effects,which indeed is why our son died from this drug.It is reporting adverse events to the FDA and the drug company and following up on your report.We can only fight within the system of the government that is in place at the moment and push for change to take place in there programs.
This is what has take place as of this year,The FDA's new 'Safe Use "iniative(which when it gets further developed will increase our partnerships with physicians as well as patients) and the July 2008 AAM report" Education in Safe and Effective Prescribing Practices" which aims to address the education of the next generation of physicians on how to best use medicines.This may help in notification practices and over prescribing but, we want the drug companies to lose the unprecedented control over the clinical research and and evaluation of there own drugs.What other company in the USA, gets to self regulate.Change will come ,we have asked for accountability by having a signature exchange when new and updated side effects are found.Full disclosure of all reported adverse events to doctors from the company representatives,with signature required upon full understanding of the benefit -risk ratio change. A prescriber should know all the good and the bad about a medicine they have chosen to dispense,if not then they should not be able to dispense it.If we were not knowledgeable about selling mushrooms and we sold the poisonous ones ,because we did not take the time it would take to educate ourselves about them,would we not be legally responsible for our actions.
Accountability is what we are asking for and maybe the candyland doctor prescribing practices would stop.They seem to ,not have a responsibility to their patients and the company has no responsibility to the prescribers,so who is responsible for our safety?
I will keep fighting for real change and all you people must do the same ,make an appointment with your representatives and have them contact our Congress representative of NY,maybe with enough onboard we can get the legislation we need to put a law in place for proper notification practices.Kirsten E. Gillibrand Member of the US House of Representatives 120 Cannon House Office Builing Washington, D.C. 20515
This is how change is made ,if you want to help please go forward and do this and don't stop until they listen.I am always willing to do whatever I can,it is physically exhausting and sometimes I just have to step away but, my daily review of this site has not stopped and my fight will continue.Dave and I sit here and our hearts just break for all but, we need people to push their Representatives they do work for the people just remind them of that.Any one with questions or that wants to communicate via private email just ask for my email address or phone number or leave me yours and a time and I will be sure to contact you,Kate M.

Just read an FDA article out today, I believe. The FDA is looking to publish quarterly a list of "potential problem drugs". That is fantastic! But where will this information be posted, and how often should a medical prescriber visit and hunt for such information?

I still maintain every medical professional with the appropriate credentials to prescribe any medication should be required to register with an email address with a database within the FDA to immediately communicate this new-found quarterly list, as well as any investigations launched (as with Merck/Singulair). Wow - what a concept.

I suppose I should be somewhat more optimistic with a slight move in the right direction - but I know with all my heart neither my daughter's pediatrician, nor my personal intern will receive, nor be aware, of any of the quarterly "lists".

Will keep trying to get a change within the FDA.

I apologize that the summary is not ready yet. At this time, I am inclined to believe that the FDA will "black box" Singulair. Maybe, I am just hoping but we will see. I also believe that the FDA will also investigate the entire category of drugs with genetic components and warn doctors that these drugs do NOT behave AS EXPECTED when the patient has a genetic variant.

I am posting this again.

I just wanted everyone to know that I am still here and concerned about everyone who is having side effects from Singulair. Sometime within the next few weeks I am going to post a summary and conclusion about all of the research that I have posted. I hope to come up with a well organized concise statement about why everyone who experiences side effects from Singulair should stop using the drug immediately. Not everyone has an adverse reaction to this drug. For those who do, it is very dangerous to continue this medication even for one more day. STOP IMMEDIATELY IF YOU SUFFER SIDE EFFECTS FROM SINGULAR. WHEN YOU SUFFER SIDE EFFECTS FROM SINGULAIR, THE REASON IS THAT YOU ARE NOT COMPATIBLE WITH THE DRUG'S GENETIC BASED MODEL. Singulair targets the CysLT1 receptor, which is a gene. This gene is not the same for everyone. If your doctor does not understand that the mode of action of Singulair has a genetic component, then tell him/her.

My son has been on Singulair off and on for two years. He goes off in the summertime since his asthma is mostly due to upper respiratory infections. He recently went back on it, maybe three weeks ago. He is 7 years old. Every morning now he wakes up with nightmares. This morning he said that he had a nightmare that all six of his webkinz were killed, except for one. The night before he said a tornado had blow our house away. There have been other nightmares too.

I decided this morning to stop Singulair, then called the allergist. The allergist agreed we should stop it and see what effect would happen. Today during school, the teacher had to call me because he was yelling at other students and was hitting books because he wanted a prize for fund raising. She said he was inconsolable.
During the summer, he was a totally different child -- easy going, laughing a lot. Now he seems stressed out, anxious and depressed.
I also noticed he has begun oversleeping.
Even worse, he was diagnosed with ADHD back in April. All of the surveys filled out by teachers and by me were from when he was on Singulair.

I know that drugs can do this to adults. I was once on a birth control pill that made me so paranoid and neurotic, I had never felt that way before. A different pill was fine and never had that happen again.

I have 2 sons with asthma that have both been taken singulair (the oldest for 3 years & his brother for 2). My younger son's asthma got alot better since he was diagnosed & he was recently taken off Singulair thanks also to my husband hearing a report about the moodiness caused. When he was on it he would cry for no reason, get very irrational & seemed to think the world was against him. In just 2 weeks he is happy & cheerful and has told me he thinks it is due to being off singulair. His older brother's asthma has gotten worse over the years & I'm concerned about taking him off but he too has crazy moods. Just tonight he started a new soccer team & got crazy & suddenly didn't even want to participate in something he loves (wanted me to let him quit right then) until we argued enough he reluctantly participated. He then came home complained of a headache (which is also way too frequent) and now has been asleep for hours. Are there any alternatives to this drug? I'm a stressed out mom that doesn't deal well with these mood swings. He is normally a social butterfly & a sweet kid but lately seems more withdrawn, more irritable (especially tonight) & complaining about leg cramps in addition to these frequent headaches. I can't deal with too many more of these evenings & wonder if all these things are possible side effects. I'm glad to see my other son doing well but miss his normally sweet brother! Even his siblings think he is acting crazy :(

unfreakinbelievable. every single drug ad I see on TV these days for new drugs claims that it will cure you of something. the only catch is: it will give you a million side-effects, half of which can be life threatening!!!

What kind of a job is the FDA doing that it lets these kinds of drugs enter the market and puts people with common problems like asthma in greater danger for developing extreme heart problems and psychological disorders???

I used Reactine. The very 1st tablet I used gave me a dream so vivid that I jumped out of bed - I was about 30% conscious and I still believed that I was in that dream. I dream that a Black Widow was in my bed right under my back and when I woke up I actually envisioned the Black Widow. Now consider that I live in Canada where BW's don't even exist. That's how powerful these drugs are and that's why you should stay away from them. I know this sounds crazy, but DON'T BELIEVE A THING YOUR DOCTOR TELLS YOU!!!!! Use common sense in common situations!!! Think for yourself and listen to your gut instinct or you will wind up dead before your time.

Hi to all,
I wanted to take a minute to say Thanks to all who post and search for answers to this drugs confusing and serious side effects.To all who have taken the time to contact the FDA and file a report to help others.Dr.Sarah Sellers is no longer the person to contact at the FDA,she has moved on after concluding her end of the investigation on Singulair.If you have a serious side effect please still take the time to file on the official FDA site for adverse event reporting.In NY. state we are still searching for legislation to help with the notification process for these serious side effects.There are to many Doctors that still do not have a clear idea of the updated side effects,and are not reporting as they should.
Letting your doctor know that good medicine is all about follow up on complaints,such as researching the singulair website to rule out that it may be the drug or it may not.Just dismissing the patient and prescribing another drug is how these drugs go undetected for so long.We want this to stop and only the unfortunate recipients of the horrors of this drug can make this happen.Again thank you for your efforts to change the system with follow through and perserverance.Our horror story is one of many and we want to help those who have survived the ravages of this drug, OUR CHILD DID NOT. Kate and Dave M.

hi everyone my name is Katie, and my son has been on Sindulair for over 6 months now. I took him off 2 nights ago, the day I found this sight. I just cant believe how many families this medication has hurt. When my son was put on, I was never told anything about anything like this happening. I thought his behavior was due to the divorce and child custody things in his life that were going on. It did not cross my mind that it could ever be this medication. He does not take anything else at all.
Some of the things we have been dealing with are, panic attacks at night, bad dreams, aggressiveness, depression, anxiety! Fits that you would not believe. Crying all the time, very emotional. And the newest one, thinking everyone he loves is going to get killed. These are not things a 6 just turned 7 year old should be going through.
I got to thinking that I needed to get him some professional help, this is not normal! I decided to look up Singulair on the net, I did not find anything. I looked up Childrens depression, and angziat, still nothing fit. Then I found this site. Wow did it blow my mind. It fit and it felt right, if you are a mom, I think you know where I am coming from. When you know you just know! So I got him off the medication, and already I am seeing changes. The first night was not grate but better than it has been in a long time, the next day though, he woke up and smiled at me for the first time in way to long, he only had 2 meltdowns that day, when he was having at lest 2 in an hr before. So far so good, I just hope that It keeps going well for him.
Thank you for letting me tell my story!

Sales of Merck's asthma and allergy drug Singulair dropped 1% to $1.1 billion for the second quarter. U.S. sales have been hurt by the recent introduction of an over-the-counter version of rival drug Zyrtec by Johnson & Johnson (JNJ), as well as concerns about the Food and Drug Administration's March alert of a possible association between Singulair and suicide and related behavioral side effects Got this off cnn money,i don't know but thought zyrtec and singulair were different drugs,my son at one time was prescribed both to take at bedtime

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.

Dear Friends,

Just want to reconfirm that this drug, that according to the Lab, present this side effects as "rarely" now we can see that it is not, I have a 2.5 year old boy, that is presenting these same side effects that you are mentioning. In a sudden he starts to act really nervous, his eyes turn red and cries while he tries to express something, but he does not know what is going on, in the meantime he has this truly visible crisis, his heartbeat goes up like hell, and his hands shakes. My wife and I got really scared the first time we experienced this with him, and we did not know what to think, we asked the Doctor and the stupid guy told us that he needed a shrink, but we did not believed it. Today he had the second same crisis, not as hard as the last one, and we discussed and came up with the idea to find out what were the side effects of this drug, and voila, is the gdm Singulair. I just can't believe that the Doctors that are prescribing these drugs do not warn the people that this may happen. The only thing that I can do is write my experience to you, thanking you for your attention, and spread the voice to the other parents that are around me that they take care of this and prevent their children to go through this process. I really feel like trash, because I did not do this before starting giving him this drug. Thanks for listening.
By the way this is an international problem, I am writing you from Mexico City.

My daughter has been off Singulair for approx 2 months and is back to her old self. Talkative and happy! How about contacting the media to see if they would be interested in doing a story on the problems that have been associated with this drug. Yesterday morning there was a story regarding the poor health of our children-high cholesterol etc, and my first thought hmm-wonder if they are on Singulair. I think if more light was put to this drug, maybe we could get answers faster.

After reading all the horror stories on here, me and my husband soon began to realize that we were having a lot of the side effects listed here and not listed on my son's actual Singulair prescription. The side effects my son had were behavioral changes, irrational behavior, inattentiveness, not able to stay on task or stay still -- in fact he broke his arm twice being so hyper, yelling, screaming and just plain mean.

We took our son off of Singulair as a trial for a few days. Immediately we began to notice differences in his behavior. He wasn't as agitated and quick to yell or get angry. (He's only 5 years old). He actually would be listening when we would speak to him. He would sit calmy and read books and the one huge thing he would do was look at us and smile. He even said to my husband once, "I love you Daddy," which just brought tears to our eyes. I never realized what a Singulair fog he was in and what it did to him. Here we were pretty close to getting him evaluated for ADHD or even Aspergers. So now we're in the same boat as others that are searching for other asthma meds to give my son. Right now we have gone back to Pulmicort, Xopenex, Nasonex and Allegra. I'm so glad I read this forum because I was desperately searching for answers for my sons behavioral issues. Oh, by the way he was on Singulair for 1-1/2 years.

I'm seeing some posts from parents who say their children have returned to normal after discontinuing the use of this medication. However, there seem to be a lot of diagnosed "ADHD" or "BIPOLAR" conditions. Are your children really returned to normal? Or have they been diagnosed with a psychological issue and are receiving treatment? There seems to be a connection here, even after discontinued use, especially male adolescents. Any thoughts?? The increase in cases of ADD, ADHD, AUTISM, etc has been multiplying at a very disturbing rate in the last 10 years. I'm thinking definite connection to the "new" breed of "receptor blockers". What is it triggering? Any thoughts out there? Lets post anyone with similar cases and see how many are out there.
