Singulair and singular

Singular has been recommended to my 3 1/2 year old son. I didn't feel good about it, so I declined and decided to look up possible side effects. Wow! I will NOT be giving it to him!
I have always been cautious on giving him antihistamines because prior bad side effects (which I never heard anyone else complain about).
When he was a few months old, he had cold like symptoms (runny nose, congestion, etc.) and was really suffering. I gave him the over-counter Pediacare and he could breathe better but he became something out of a horror film. He screamed constantly for over 48 hours and did NOT sleep a wink! Like a "crack baby" or something. (I assure you I am not exaggerating). I too became sleep deprived and crazed by his constant screaming, it took me some time to realize it was the meds. When I quit giving it to him, he became normal again. I decided I had to deal with the symptoms and not give him meds.
A year later, different medicine, I tried again. Same results.
When he was 2 1/2 we took a road trip from KY to KS. I thought I would try Benedryl, he had 2 older syblings that it benefited. NOT for him. He became "crazy" and screamed to the top of his lungs for the entire 12 hour drive. I vowed never again (for him or his family).
I have had success with Claritin in less than normal dosing. With no side effects. I have been assured, however, that Singular would work better for the symptoms. No thanks.
I feel really bad everyone this has effected negatively. I understand the side effects first hand.
I too have heard of the "antihistamine blocker" but don't know if it works.
I plan on trying a "nettie pot" (natural alternative) and have heard great allergy success stories. You can get them for about $5 at Walmart.
Hang in there parents! Do what you have to do for your child. Trust your instinks even over the Peditrician. I love Docs but YOU know your child. :)

Hi,
I'm a 38 year old woman who went on Singulair in September of 2006. By December of that year I started experiencing heart palpitations,dizziness,and nightmares that stayed with me in my waking hours. By January of 2007 I was having full blown anxiety attacks. My doctor ran every test under the sun and I went to several therapists. By the end of January my doctor had me on Effexor, and several other short term aids such as atavan. The summer of 2007 I started experiencing stomach pains and sever diarrhea. As much as I loved my 20 pound weight loss, it was not a lot of fun. Again every test under the sun showed nothing. This spring I heard of the concerns of Singulair and immediately went off of it. Within a few weeks I felt like my old self. I am still weaning off of the Effexor and my asthma is not as good as it was on the Singular, but it is worth having my health and my life back. I feel that Singular almost ruined 2 years of my life. It should be taken off of the market.

This is so scary!! I was just looking up "my son says he hates himself" on google, because I was concerned, as I deal with depression and wanted to find out if a little boy saying this (6 yo) is normal or if it may be signs of depression. Weirdly this link for singular came up.
My son DOES take singular for his asthma and has been taking it for about a year on and off. I have tried to take him off because I hate feeling like a pill pusher, but then his asthma flairs up again. So I put him back on it.
But today he has just been whining and crying (he is still crying and screaming for me loudly now!) and I began to get VERY concerned that my son was exhibiting signs of depression. If this is true, we may need to file a lawsuit against the drug companies as there are too many similarities and coincidences with this singulair. It wasn't even a THOUGHT or consideration that the medicine could have been causing this. I just thought that he was growing up and just goind through stages. Now I feel stuck because I don't know whether I should take him off and risk his asthma flaring up, or keep him on and risk his depression gene flaring up. This is VERY scary....

I'm an adult female with severe sinus polyps, adult onset asthma and allergies. Initially Singular seemed to be helping my nasal polyps, when nothing else helped in any way. I made several attempts to use Singular, and proved repeatedly that this medication did, in fact, cause me severe side effects - even when I used a childs dosage. While using an adult rx for Singular, I immediately began experiencing horrific nightmares (which I have never had in my entire life). I also had extreme knife like pains in both ears, which made me feel like I had a severe ear infection, chest pains where it felt like a cinder block was lying on my chest, and migraine like headaches (which I've never had). I stopped the medication after about a week and the nightmares went completely away, but it took me a couple weeks to recover completely because I developed what felt like a respiratory infection and ear infection as soon as I stopped using it. Because Singular seemed to slightly reduce my nasal polyps on my first attempt, my allergist suggested I try using it again - almost a year later. When I first began, I completely forgot about the negative side effect and why I stopped using it in the first place, and just gave it another try. I again experienced the same horrific nightmares, ear pains, but this time got a strange rash/cluster of blisters under both eyelids which my eye doctor confirmed was an allergic reaction to something I was using. Singular was the only medication I had changed. My allergist thought I should give it longer to see if the symptoms went away (because they probably weren't caused by this medication - and were due to something else ???). Fearing going to sleep, I decided to try taking the medication in the morning instead of night, and had my physician reduce my rx to a childs dosage (5mg). The nightmares lessened, and the blisters under my eyelids went down, so I continued using Singular for about a years time. What I didn't realize, was that over this time I was becoming depressed, fatigued, and became easily agitated and short-tempered, which was very different since I was normally a very happy, energetic mom. My nasal breathing seemed to be slightly improved, so I just kept taking the medication - not realizing that it was causing all of the other problems I was experiencing. I became so fatigued and depressed feeling, that all I wanted to do after I got my kids off to school was to sleep until it was time to pick them up in the afternoon. I was also experiencing stomach pains for unknown reasons. I was certainly not myself. I didn't realize that while I was using Singular I had lost complete interest in everything that I normally loved in my life. And please note I'm 45 years old, and I was using a childs dosage. ( I can only imagine what this medication does to a child. )Fortunately for me, I accidentally forgot to refill my prescription for a few days and noticed that my depression started to improve. I decided not to refill my rx and stay off it to see if I continued to improve - and I have. Unfortunately, even though my depression has all but gone away, I'm experiencing symptoms which must be from withdrawal of the medication - and they are just as scary as the side effects were. Now that I'm not taking Singulair any more (and I've made no other medication changes), I have extreme fatigue beyond belief, and ache everywhere. My muscles are in such pain that I'm having difficulty doing things I would normally do. I have extreme weakness in both arms and legs, and my back aches almost constantly. And strangly enough, my asthma and allergies have slightly improved since stopping Singular - I thought for sure my allergies/asthma would worsen when I stopped completely - but they did not. All I can say is - please trust what your body is telling you - even if your physician tells you otherwise, and do not use this medication or any other if you experience adverse side effects to it. I would never give this medication to a child that wasn't old enough to tell me what he/she was experiencing, and would document the childs temperament, ailments if any, and what changed once the medication was started - and discontinue it immediately if even one adverse side effects occurred. One last note - I am still experiencing vision problems, which I feel are due to using this medication. Hopefully, no other permanent damage to my body will result from the Singular that I've already used - and I hope you Singular users will recover completely too from its dangerous side effects. Wishing you the best of health!

I was searching for a site with the side effects of Singulair for my son who is 10 and has been taking Singulair since he was 2. It was a life-saving drug for him and his life has been wonderful since then (as far as asthma goes). He is a very athletic boy who plays every sport he can and he is still a little overweight with cellulite and love handles. I had heard that maybe it might be the Singulair so I decided to check it out. Little did I know about all of these other side effects. He's been taking it for so long that I assumed his depressed personality was just the way he was. He has also had such horrific nightmares and he's convinced he has a ghost in his room that shakes his bed that I was really starting to consider that maybe he might. His brother sleeps in the same room and does not have any of these experiences (also on Singulair). I am SHOCKED! I only read about 20 entries but I'm going to read more. Has anyone had the weight gain problem? Thank you for anything you can share.

Thank you for sharing your experiences with this medication. My 4 (almost 5) yo has been on Singulair for almost 2 years now for allergies. I've noticed over the past few months a slow change in his behavior/attitude, not positive changes. He's become an aggressive, angry child that can be set off in a split second over nothing. He's also getting worse with not wanting to go into other parts of our home alone. He won't even walk down a short hall to go to the bathroom alone - is afraid of I don't know what. Lately, he's also been obviously having bad dreams because he kicks and yells in his sleep. I've just chalked all of this up to his age. While taking a walk yesterday I ran into a neighbor that was telling me the doctors want to put her son on Singulair but because of the possible hyperactivity and other side effects she won't do it. I came home and found this site along with others describing similar side effects as my sons. As of last night, we took him off of Singulair. I'm curious to see if this is the problem. I'll keep you posted.

I just started the Singular and it has helped my asthma a lot. I can't tell about the coughing because I also started it while I had a cold. But now and then even before I took singluar I would cough. Sometimes coughs are produced from various types of airborne things, many different types of things. I have a mold aggreviated asthma so that could be why its helping my instead of causing me to go nuts like it does for some. But it doesn't sound like a very good drug for children. It seems as though none of the posts coming from children taken Singular are positive. But so far it's helping me. I made it through the day without grabbing for my inhaler which was a great relief for once.

My son has been taking Singular for a few years for mild asthma and recently in the past few months all of the sudden he has been having a hard time falling asleep,anxiety at bedtime taking hours to get to sleep with me having to stay in the room. We took him to his pediatrician who ran blood tests and referred me to a sleep specialist who suggested he may have OCD or Anxiety. I just thought it was just something that would pass after 4 months it still has not passed. I am removing him from Singular TODAY. After all these visits with these doctors who knew he was on the medication and never said anything to me about possible side effects . I cant believe it took an article my husband saw in the paper for this to come to my attention.

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 6 y/o daughter has been taking Singular for approx. 2 years. She began to have regular stomach pains shortly there after. She was sent to Children's hospital where they put her on a laxitive which made things worse. Then we began testing for food allergies only to find out that she tested positive for a 3 page list of foods. We eliminated those food and had her tested again. She was subsequently allergic to the foods we eliminated. She was recently down to rice, a few meats and some vegetables. Guess what, she is now allergic to those foods.

All this time she has been complaining of severe leg pain, eye pain, throat pain, numbness and tingling in her hands a feet, all of which come an go. I have reported this to all the doctors and specialists we have seen. She had undergone countless blood tests to rule out autoimmune disorders and all come up negative.

She began to develop severe anxiety and just had the blues most of the time. She would be crying and saying off the wall things like, "I don't think my fish is happy". She couldn't stand to be away from me and would stress out about even weather or not she would sit by me at a restaurant. I mentioned this to all of the doctors. They said to not make too much of it. One suggested she see a psychologist. NOT ONE DOCTOR EVER LOOKED AT THE SINGULAR.

Finally about 4 weeks ago my neighbor who is a scientist at a pharmaceutical company called me and told me about the "black box" warning that had just come out on Singular. I took both of my children off of it immediately. My daughter went through about a 10 day period where her anxiety got worse and then it was just gone. We are adding foods back into her diet and at this point she has not had any severe allergic reactions.

The last 2 years have been a complete nightmare for her and for us. I am a medical professional and I have had doctors treat me like a hypocondriac, hypersensitive, attention seeking mother. I feel so justified and saddened by the recent findings all at the same time. Most of all I am so grateful that we figured this out before things go even worse.

Please let me know if anyone else is suffering food related reactions as a side effect.

I am 16 and have been on Singular since July 9th of this year and the only side effects that has been affecting me that I really notice is the ear infections and headaches. my mom and I think that I might have one right now but have not gotten the chance to make a doctors appointment. The other side effects that I read about while googling it were a sore throat and upper respiratory infections which are both things that I have been fighting since March, which is what lead to me being diagnosed with asthma. In response to the person that was talking about asthmex, I also got put on that the same day and the only side effect that I had from that is a higher blood pressure that usual but it was still in the normal range, caused by the steroid in it.

I have been reading all of these posts and have another question. I hope that someone can help. My daughter, 8 years old, has been on Singulair since she was 4. She is normally a very happy girl with a wonderful disposition. For the last year or so, she has been having trouble getting herself to sleep at night. She says that she hears things in her head such as ringing or "noises". A few hours before she knows it's bedtime, she cries and when we ask her why she's crying, she can't give us a reason. We initially thought that she was crying for no reason because she didn't want to go to sleep. I remember reading about the side effects of Singulair causing mood swings, etc., but her's are not violent mood swings. Just very emotional and has a hard time coming down from the "episode". I'm at a loss...I have not talked to her doctor yet about it, but have told her that we will make an appointment this week to discuss it with him. My husband suggested that maybe it sounded like she was having a panic attack or anxiety attack. I hate to label her as that at such a young age. My mind now goes back to the side effects of Singulair and maybe this is to blame. Any help or suggestions would be greatly appreciated. Thank you! Concerned Mom

My 6 year old was prescribed singular for allergy relief. After 1 night of taking it he woke up with leg pain. Not too severe, just sore so I thought they were just growing pains. After the 2nd night of the medicine he woke up and his legs hurt so badly that he has a very difficult time walking. We took him off the medice. After the 3rd night with no medication he woke up with a little leg pain, but not anything like the previous day. After the 4th night he was fine and has been fine every since. It had to be the singular. My pediatrician did not have any other children that had had this type of reaction, but said that we should not give it to him again. He said that we should listen to our bodies, and if we don't feel right after medication then we should stop taking it. It was scary for my little boy

I'm a 45 yr old female, I've been on Singular for many years (originally for allergies and then asthma too) and have quit three times due to "possible" side effects and tried other asthma medicines. Inhalers make my GERD worse and I'm anxious all the time. I have to say Singular is the only thing that really works for my asthma and I keep going back to it because it does work. Also, I found that when I quit and expected my depression, headaches or fibromyalgia to go away they didn't... so I own these symptoms now regardless of Singular. I've always had mild depression and anxiety and all the prescription drugs for this I find are really too strong and are made worse then by Singular. For mild depression I find taking SAMe and St. John's Wort to really help me. Can't say if it would help others but you might look into it. I think it's important that doctors understand a link with depression and Singular but for some of us there's not another choice.

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.

I have a 2 1/2 year old daughter who was put on Singular about 3 months ago. About a week after taking it she began to break out in hives. Has anyone else observed this in their child? I took her to an allergist who ran all kinds of tests and they said that she was allergic to nothing. I am taking her off of it to see if the hives go away. She is also very moody, cries all the time, is very aggressive. She was never like that until she began taking this drug. Of course, the allergist said it was not Singular, and for me to continue giving it to her.

One month on the drug became aggressive and moody got very anxious about everything to the point of dibilatatingpanic issues. I am a 46 year old male, working full time and attending college at night.Singular has made me almost drop out in my senior year due to panic issues in class.I am now off the drug one complete week feeling better still having mild panic issues.
Does anyone know how long it takes to get out of your system?

I've posted before about the horrible effects this med has had on my daughter. Two months off and she's doing much better.
I received emails from ****** published by web md, it gives reent ifo in the world of medicine, recent studies etc. I just received one and there was an article comparing the long term side effects of varios asthma treatments for children. Of course singular was one of the meds mentiones. Think it said anything about the real side effect, of course not, only focus was on it's ability to control asthma. It makes me so mad, this article doesn't give any indications that doctors shouldn't prescribe it to kids.

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.

I'm 50, a lifelong asthmatic (since age of 4). I started taking singular in 1999, Time Magazine's cover story back then. In the spring on 2001 I had stopped taking it. I got sick and my doctor had me taking it again. I told him subseqently that I had noticed changes in my moods. He dismissed the notion. I worked on wall street. 911 came and I was put on antidepressants (zoloft 200mg/day and gabatril 8mg a day). I lost seven years of my life. Yesterday I spoke to my pharmacist. I'm now on disability (respiratory, depression and anxiety). Medicare Prescription plan would not pay for Advair. The pharmacist to my surprise pointed out that depression was written up as a potential side effect of singular. I have read that head meds may leave 70% of those taking them left them still depress and with sleep disorders etc. I have been off the head meds for 9 months now. The mental fog has cleared, (from not being sedated).). An my depression continues unabaited as it has for the past ten years.

I also found out that MAXAIR is back after being discontinued. I used it for at least ten years (in the 80 & 90's). It has nt steroids, long lasting compared to albuteral as an emergency inhalher and precluded the need for multiple asthma meds. My life changed when Maxair was not being bottled which was just about the time Singular came out. I doubt it will undo 10 years of environmental injury and damage caused by singular and steroids. I also believe the best advice for keeping me breathing freely was drinking lots of water, (distilled, I bought a machine rather than carry a gallon a day from the store.). was truely life improving. It allows your body to flush out the impurities our modern day life threatens us with. I read the posts on this site and was compelled to share my personal experience(s), for you to consider....

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...

My son is 6 years old and he has been on and off Singulair for about 2 years. He was off since last Fall 2007, but was put back on in April 2008 for allergies. He began telling me that he was having "dreams" during the day. He would then tell me these totally bizarre thoughts, "dreams" that he was having. They were very strange and perverted and violent. I asked him why he was saying this stuff and he said, "I just can't help it, they pop into my mind." I thought that he was going through a phase because he was bored. He is in 1/2 day kindergarten and I attributed this to too much television and boredom. I was thinking that someone was feeding him this crazy information (kids on bus, class, etc.) and he was repeating it to me. He was too showing OCD symptoms, afraid if he touched his feet- "is that dirty??" afraid if he touched someone's hand, "is that dirty if I touched Tim's hand?" He would also cry and whine often over the simplest things. I thought this was a phase. Our prescription for Singulair ran out and I did not fill. I started noticing a change over a week's time period. My little boy who was coming to me several times a day with bizarre "dreams" had not mentioned them at all. His compulsive behavior has stopped and so has the whining. I feel lucky that I did not fill the prescription because I would not have even thought it was the singular, since there are no side effects like the one's I mentioned above on the label. I am sick about this!!

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.

Well, we just got out of the ENT and he couldn't believe that his ped put him on Singulair. He said he didn't like it, it wasn't a good drug, and hadn't heard of many good things about it. He also told me to take my son off immediately, to bad I already had. He also wanted me to put him back on Zyrtec but only when needed, not every day like he had been taking it. Told him about how the neb. had been talked about so he listened to my little one's lungs and he said that they are all clear and there is no need for one. While I was in this appointment, his ped. called. She said that she had never heard of any side effects with this and she wanted him to stay on it for a week to see if it worked or not. Sorry we aren't doing that, we had four doses of it and that is more than enough to say we aren't staying with it. This is just his first full day off the med and I shouldn't get all worked up but while in the waiting room to see the ENT we had two huge fits and even hit his head on one of the chairs because he didn't get his way. The ENT said to give him about a week to go threw "detox" and get it out of his system and then he should be back to himself.

Also, on top of the big mood changes and swings we didn't sleep good last night and had another fit of rage in the waiting room of the ENT. Not fun at all.

I'AM A 69 YEAR OLD WOMEN TAKING SINGULAR EVERY NIGHT SINCE
APRIL I WAS GIVEN IT TO SUPPLEMENT MY ADVAIR (TAKEN AM & PM)
AS I HAVE COPD ALMOST FROM THE OUTSET I DEVELOPED A COUGH
NOT HACKING BUT ANNOYING I LIVED WITH IT NOW I DEVELOPED
A HOARSENESS TO MY VOICE THAT YOU CAN HARDLY HEAR OR MAKE
OUT WHAT I'M SAYING STARTED TO WORRY ABOUT THIS SO CALLED MY PULMONARY DR & HE HAS TAKEN ME OFF IT FOR 1 WEEK STARTING TODAY 6/6 I'AM TO CALL HIM TO LET HIM KNOW IF MY VOICE
CLEARS

hi, im not sure what to do. my 3 1/2 year old daughter was today given the prescription for singulair. i voiced my concerns to the doctor after my friend telling me its no good due to the side effects.she said that there are risks and side effects with any drug you take but for some reason i don't feel right about this. don't doctors know better than this. anyway Would like to know if all the people who take singulair suffer some sort of side affects or is it minimal? or going by this side it looks like its probably best not to give it to her at all.

My son (27 months old) has been taking Singular for about a month and a half now to treat his asthma. His asthma is doing great, but since he started taking Singular he has been having awful nightmares. At the suggestion of his doctor we started giving him his medication in the morning instead of at night to see what happened. That just started effecting his naps and night-time sleep.
The doctor is now suggesting taking him off the Singular to see if he nightmares stop. I'm hoping everything improves after stopping Singular, but don't know what to do about the asthma.

In September of 2007 my then 13 year old daughter was put on Singular for mild asthma. At the time she was a straight A student, vice president of our school and a popular girl who's guidance counselor described as "the glue of her grade" because she was so well liked. In November she told me that she was struggling with advanced Latin and Science. She asked to drop down to on grade Latin so we did. In December her science teacher notified us that she had a C average. She told me that she thought she had ADD/ADHD and she couldn't keep up. At the same time she was having a lot of problems with friends at school and we just attributed it to being 14. 3 weeks ago we discovered that she is significantly behind in English and it was then that she told me that she is been having horrific night mares. She said that they usually involve someone killing her or her killing herself. She said that they were so graphic that she couldn't repeat it out loud. She also said that she would feel waves of anxiety that would come over her at school and she would act "witchy" to the kids in her class for no real reason. She said that sometimes when she is trying to do her homework she will read the same passage for 2 hours and still have no idea what it's about. She also said that the suicidal thoughts from her sleep happened during they day and that she had thoughts of her harming herself. Fortunately her pulminologist told us that this may be caused by singular and we immediately took her off of it which was 2 weeks ago. She has only had 1 "bad dream" not even a nightmare since. She had one anxiety attack 3 days after she was off it and she describes her moods as the "cloud lifting....slowly". Now, we have to pick up the pieces. Her grades have suffered, her friendships have suffered and most of all her self esteem is very low. I'm grateful that we found out the cause but I feel as if my daughter lost a year of her life and I worry that because Merck won't admit there are side effects we can't find out how long it remains in their system. Is anyone else concerned about the long term affect and has anyone pursued a class action suit to try to get this drug tested properly?

I just viewed a commercial for Singulair now marketing directly to children. Has anyone seen it? They're promoting cherry flavored chewables and a cute little kitten in the background. The side effects so many of us have experienced with our children are still not mentioned instead they've done the exact opposite. With this drug under investigation(Dr. Sarah Sellers has already sent a personal email from the FDA) this is immoral! What can we do to stop any more children from being injured? Merck has no ethics, NONE!

I have been on Singular for the past three years. I usually take a tablet in the evening at the same time I take a baby aspirin and Nyaspan (cholesterol). I didn't seem to have any problems except waking up periodically throughout the evening; thought this was due to age (63). I was without my Singular for about 10 days and then got a new prescription filled. When I took the first tablet I went to sleep and was awakened by a "burning, prickly" sensation im my arms, chest, face and thighs. I went into the bathroom and found myself covered with what I would call hives. I felt hot. Thank heaven I had some liquid Benadryl. After about 30 minutes I finally could relax enough to get back to sleep. By the next morning all that was left was a slight red "glow"; could have thought I went for a tanning session. The pharmacist couldn't give me an answer; I am now waiting for my doctor's input. In the meantime...I'll skip the Singular. (next time it may affect my breathing)

One more thing I have noticed is OCD behavior. He is constantly rubbing his index finger and thumb together. At first it was one hand, now it is both hands. This has been going on for about 2 months. When asked why, he says he 'just feels like he has to do it'....

My son is almost 6 yrs old. He has been taking Singular for approx 3 years, in addition to Claritin and Nasonex. This is all for his allergy to mold. His doctor started him on these meds after a 6 month episode with sinus infections leading to asthma-like symptoms. We have not noticed anything unusual about his behavior until approx 3 months ago. He started waking up every night (2-3 hours after going to bed) with bad dreams. At first he would not fully awaken and fall back asleep immediately. After a month or so of this happening most nights, he had two nights in a row where he woke up screaming and was inconsolable for about 30 minutes. We initially thought it was night terrors, but he was not scared or fearful, he was just upset/angry. He would hit the bed repeatedly and yell. He didn't know what he was upset about but would talk about how he thought we hated him, he was dumb, etc. After about 30 min he would 'snap out of it' and return to his normal self and go back to sleep easily.
At first we thought these were night terror brought on by a recent fever, but he had another episode last night. He has also been falling apart at the littlest things and getting quite violent (for a 6 yr old). He was sent to his room yesterday evening because he was complaining about the dinner his mom made (lots of complaining these days..). He had a total melt down an started throwing things and hitting the door so hard he put a hole in it.
Some of this behavior I would chalk up to normal kid stuff, new baby brother, etc. But I am suspicious about the negative thoughts, bad dreams, and instant melt downs... I stopped giving him Singular today and we will see what happens. God bless you all as we figure these things out...

Wow, I just found this site. The child that had strep especially caught my attention. My daughter, 11, has been diagnosed with PANDAS, which is also a controversial diagnosis. I'm not sure when she went on Singular, but it was a couple of years ago due to allergies. She had bad reactions to anti-histamines. For the past two years we have been dealing with just about every issue posted here. Physical pains, stomach, headaches, joints. urination issues, high cholesterol, but the worst have been the irritability , mood issues, OCD, fears of cutting herself, bad thoughts, suicidal ideation. She was on Zoloft which made things worse, She was hospitalized at her own request. She was placed on Prozac. She's had years of therapy. She would say life is just so hard and she wants to be a normal kid. About a month ago her pediatrician mentioned that there were some reports about Singular and it would be something to watch for and discuss with the psychiatrist, He didn't seem to know much about it. Last week after another suicidal ideation I decided to research the singular issue. I had been attributing everything to the PANDAs. I was so surprised to see the similarities. I took her off of it Friday and have seen some changes already. I hope we see that continued improvement. Thanks to all who have shared stories, it's so helpful. To have hope that you'll get your kid back is great.

Our son was put on Singular almost 2 years ago to help with his "moderate" asthma. It has been the hardest 2 years for our family. My son who was already very senstive became very depressed. He showed no interest in anything. He was always sad and very down on himself. He had awful night terrors/nightmares. He didn't want to go to school or do anything. We continued to sign him up for sports/piano/scouts and it was a battle to get him to go. He always had headaches, which I thought were because of dehydration and made him drink water. We had him seeing a therapist trying to help him with the sleeping problems and the depression. We switched his room with his sister to physically make him closer to us at night. He was anxious and very irritable. If something went wrong, he couldn't handle it and had complete meltdowns. If he didn't eat anything for a while and his blood sugar got low, he was uncontrollable. To add to the problem was he was never hungry so I would have to force him to eat something about every 2-3 hours to prevent the meltdown.

The good news is that he has been off of Singular for over a month now and he is a new kid. He is excited to go to practice and will ask his dad to play catch with him in the yard. He is happier and we have not heard once "this is the worst day ever" which we had heard all the time before. He has not had one headache and seems to have a little bit of his appetite back. He is happy and holding his head high. Now, he still doesn't want to go to school (what 8 year old boy does), but he doesn't fight me when I tell him it is time to go. He does not have the meltdowns or the irritability. He even showed some empathy to my husband last week.

My husband and I are amazed at how different he is. We are also very upset that for almost 2 years we made his life miserable by forcing him to take this drug. I think for kids that are already sensitive to things it heightens everything! I am filing a complaint with the FDA and spreading the news to all my family and friends. I hope this information helps! I know I have learned a lot from reading these posts.

I'm an 18 year old male and I've been taking Singulair for years; I don't even remember when I started taking it. I've had chronic sinusitis my whole life, and use a Singulair 10mg/ Allegra 180mg combo to control it. I never gave it a second thought. From my adolescent years on, I've been able to sleep (if undisturbed) for 15, 16+ hours a night, and have always felt like I was in a fog during everyday life. Getting out of bed has always been a terrible problem for me.

Throughout high school, I became progressively more depressed and apathetic toward school work, to the point where I dropped a number of classes my junior year. Got put on Prozac for a while, it helped a great deal with the depression, and seemed to give me enough energy to get through the week. I discontinued it after a year or so, everything was going okay (aside from mood swings and tiredness- explained away as symptoms of my age/hormones/going to bed too late), and then I went to college.

I had a mild depression that I think most people get upon leaving home for the first time, but the real problem was anxiety; I had a number of anxiety attacks, and decided to transfer to a school closer to home. I started Celexa and therapy- the celexa seems to take the edge off, but I fear its making me even more tired than before.

I've just heard about the whole Singulair controversy, and I am not taking it from here on out. I really hope that this whole ordeal was brought on primarily by the Singulair. After a month or two, I'll repost to report whether the symptoms went away.

I don't know if my 1 1 /2 year old son's being diagnosed with low igG and low IgA have anything to do with singular. He just got off it 2 weeks ago, had been on it a year. He was tested for allergies everything was negative, but tested very high positive to gliadin IgG (95.5), and positive to gliadin IgA (14.8). Is this related???? HELP!!!!!! The GI Dr want to do an endoscopy on Friday May 2. Any help, I don't want my son under anesthesia unnecessarily..................

My son has been on Singulair now 5 years and I am in the middle of fighting to get him off. My son is now 7 years old and has been diagnosed with allergies (no test have been done which I find very odd), which leads to a case of mild asthma. This past weekend his mother forgot his Singular on Friday so I could not give him any till the next day, where we met at his soccer game. Saturday night I gave him his usual pill and thankfully due to his exhaustion from playing out side all day he went to sleep in 10 min. vs 3 hrs later which is the norm since Singulair seems to jack him up.
He also has red puffiness under his eyes - most likely allergies.
Seems depressed - just driving down the road and I look at him in the rear view mirror and he just sits and stares into space. When I ask what's wrong he either says nothing or I am tired.
He will try to tell a story or think for himself and just stops mid sentence and says " never mind I am just confused"
He will be having fun one moment and just starts crying or gets depressed.
He was throwing a ball in the house (yes I know) and accidentally knocked a glass over breaking it - he went running to his room, crawled under his bed and sobbed profusely for over 30 min.
He has a hard time doing / focusing on homework - becomes bored very easily.
Does not want to go outside. I will take him to allot of cultural events/ hands on or participation events - he will not try anything. He is unsure and will not come out of his box so to speak.
I spoke with his doctor who was reluctant to take him off, but then agreed that if it was OK with the ex, to take him off for a week to see what happens.
The fun part: My ex is convinced that since he has been on Singulair for 5 years he is fine and does not need to come off it.

1.) Son is diagnosed with mild asthma or allergy induced asthma.
He has never had an allergy test done and has not had a lung function test in over a year.

2.) It is documented that our son has four outbreaks a year. (sounds like the changing of the seasons) but is given Singulair all year round and the dosage has also been increased.

3.) Since the court order, ordered my ex to enroll our son in sports (she would not let him play anything) he does not wheeze or cough uncontrollably.

4.) Since I had to battle to get our son on my insurance I have cut her control issues off a little, but she is refusing to take him off Singular just for a week to see how he reacts. Although I do agree that he should have some form of allergies medicine.

5.) When I found out about the side effects of Singulair, I also found that his doctor was getting ready to add two other allergy medicines to his portfolio - totaling 3 different meds.

I see our sons behavior getting worse and I watch him turn into something he is not and with a controlling individual not believing anything about the side effects it looks like I will have to rely on the medical system to prove my point. I do believe he needs to be accurately tested for allergies and given a regularly lung function test but most of all since he is now on my insurance, a second opinion and a 3rd to narrow down what the situation is and an alternative medical procedure that is fit for the symptoms.

I am a 57 year old man, who has been suffering from asthma several years. This spring my doctor put me on Singulair as an additional medicine to my cortisone-inhalator. after one month I feel symptoms of depression an mood-changing, severe ups and downs.
AND - as an additional symptom i have partially lost my feeling in some fingertips, and now parts of my left thumb and even a feeling of "cold2, mostly in my left hand.
anyone who share that symptom?

My 13 yr old daughter was put on Singulair along with Asmanex and Clarinex for her asthma about 6 weeks ago. Everything seemed to be going very well at first and her symptoms were starting to get controlled. I started noticing after about 3 to 4 weeks that her temper and attitude were getting much worse. Anyone with children this age knows what I mean but this was like a 180 degree turn for her. Her actions were becoming totally out of character. Before I knew it she would cry and get highly upset over the least little thing. Week 5 came around and things totally bottomed out. She came home from school and WAS NOT HERSELF. Made comments about how she hated her life and it was not worth living. Later that evening we had a big argument because I was telling her nothing was worth saying that. She went totally out of control and I had to physically restrain her to calm her down. It appeared everything was better so she went to her room. I went down to check on her and she calmly told me that she had taken advil and tylenol pm and things would be better for her forever now. We went to the ER where they made us wait for at least an hour, then finally took her back. She had to drink two cups of charcoal and was poked and prodded repeatedly. They did a catheter to get a urine sample. She was very cooperative but also was in a complete daze so who knows. The poor child couldn't even lift her head up when she started the vomiting to get rid of the drugs. It was very upsetting and sad. Her heart rate and blood pressure went very low and I really thought in the back of my mind that this was it. Finally, after several hours she started coming out of it and they sent us home. The next evening when she was starting to really come around she proceeded to tell me how she had been seeing a man walking around in her bedroom at night and she was afraid to go down there. Breaking down and crying telling me about all of the horrible nightmares she had been having recently and didn't know why. I thought what am I dealing with here? This just isn't her. Three days ago I heard about singulair in the news and looked it up on the internet. OH MY GOD THIS SOUNDED LIKE US!!!!! I immediately had her stop taking it and the next day phoned her asthma specialist who agreed she should stop now. We are going to watch her for two weeks and see if any symptoms return and then decide if she needs something else or will be fine on just the Asmanex. As a side note, she also mentioned being unable to concentrate in school (unable to do even the simplest math problems) and that her brain felt confused or like something was missing. She said this had been bothering her for several weeks. I know it was this drug. They really need to take this off the market NOW and stop flirting with disaster. The only reason I posted this was to let others know they are not alone.

I usually have allergy headaches in the morning which would go away after taking 1 Benadryl w/ Tylenol. About a week ago my doctor started me on Singulair because she was concerned about me taking Tylenol daily. The last few days I've had terrible headaches that linger most of the day. (I've continued to take the Benadryl w/ Tylenol to try to help the headaches, but it's just not working.) Today is day 7 with the Singulair, and the headaches seem to be getting worse. Are headaches common with Singulair?

Hi.

I was put on Singulair toward the end of February. At the beginning of March I started getting hives all over my body and becoming very itchy for no reason at all. The allergist said it couldn't have been from the medicine. The frequency of the hives/itchiness have slowed, but I still get them. I was also getting a little dizzy when I'd put my hed back or lay down, but I knew that was one of the side effect. But, the past several days, I've been getting very dizzy when I walk. I'm worried this is from the Singulair -- nothing else has changed. Could these effects show up after a month? My allergist doesn't seem too concerned, but I am.

I have to say this after reviewing two major areas:

1. the brain
2. mast cell homeostasis

I desperately wanted to be POLITICALLY CORRECT and say that side effects can be confined to the minority. God, how do you fight Merck?

In this case, it would seem that the real benefit of this drug is to those with the extreme type immune responses whose body chemistry has been altered by being hyper-sensitive to some type of "invader. Extreme can be defined as just not the average or beyond that.

So, if the truth comes out that essentially normal immune systems don't need Singular at all, then I have come clean. I certainly have doubts whether essentially normal systems need this at all.

My M.D had prescribed Singulair approximately 3 months ago. I was extremely hesitant to take it and did research online before i made my final decision. I am/was fortunate not to have many of the side effects as stated in the other postings. Upon filing the second refill, I noticed I was putting on weight. My eating habits and daily routine has not changed prior to taking Singular or during taking the course of taking the pill. I started to become very concerned and I too found this site. I can tell you for a fact, that there is a very definite side effect of weight gain. I have gained weight all over my body, not only limited to the stomach area. As a result, I too, will NOT continue taking this pill, not only because of the weight gain, but in addition to the fact that my allergies are still bothering me. I am going to try Zyrtec, which is now an over- the -counter allergy pill. Zyrtec, until last year, was by prescription only. In final, to all those that are complaining of weight gain and various serious side effects, you are not crazy, The symptoms you are experiencing are real. Good luck to all of you.

Hi guys,
I came to this forum after a client at our firm told me to check out whats happening with singular. I am not a lawyer, but I am a secretary for a med mal firm and I can tell you that we have already started taking these cases. I saw a few questions posted about whether you had to wait 9 months for the investigation to finish, but that doesn't stop you from filing suit. If it were my baby boy, I would switch meds, but if you can't--make sure you journal EVERYTHING. Take videos of outbursts, etc. We have one client who's son is self mutilating after using singular. If thats happening to you, try to document the episodes. Like I said, im not a lawyer, but I work for some so I can answer a lot of questions and I would be more than willing to help. I am so disgusted by what I have read. Please email me if you have any legal questions, etc. If i can't answer them, my boss will and if its a medical question, we have a staff nurse so I will give her a call. Again, I am so sorry for what everyone is going through. I pray to god I can help in some way.

Ok I haven't been following along for several days so I may have missed some info. But what I'm wanting to know is if anyone out there has had the their child off singular for several months and had the attitude problem get worse rather than better. I don't know what is going on with my son but he has been off the meds for almost 7 months and within the last month turned very mean and ill-tempered. We would get this reaction sometimes while he was on the medicine but now it's 10X worse. Could be totally unrelated, but I thought I'd through it out there just to see.

I talked to my childs Dr today and she had no idea about all the problems with Singular but she did recommend that I take him off of it for a couple of months just to see if it helps with some of his symtoms or all of them.. But I also find it very discomforting that drug reps that promote these drugs to dr offices usually have no pharmacutical background at all that all they do is go tell the drs what they were told about the drug.. I think there needs to be guidelines in place for drug reps to have some sort of pharmacutical knowledge and background before taking these drugs to drs to get them to give it to us as adults and more for our childern something needs to be done. How many people have to be hurt before they take notice...
My thoughts a prayers go out to everyone who is dealing with this nightmare if you all are having as much problems with your children as I am we and mostly our children need all the prayers they can get.....

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.

about 2 hours ago on Apr 11, 2008 by catherineevans, #7045
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.

has anyone took their child off of singular for more than 2 weeks and has the child had any breathing issues since being off?

My son is off singulair for two weeks now and is showing improvements. He was on it for 7 years and at the beginning we blamed it on steriods, even though his dose was low. When he went off the steroids, the behavior didn't stop. I questioned the allerist if the singulair could be doing it, but was told no, it doesn't have those side effects. I don't blame the doctors because they weren't given the info. He was extremely emotional, cried for no reason, had no confidence, didn't like himself. We on more than one occasion have told his older sister that when he hits his teenage years we would have to watch him for suicide, as his reaction to problems was sooo out of whack! He was on motrin for headaches 4-5 days a week(blamed it on sinusses). Unexplained stomachaches. These symptoms came on over years, not right away. I have always thought that the steroids had done damage because he took them when he was so young. Until the news reports hit, and I started reading other people's stories and doing the "OMG, that's my kid!", I never put the problems on singulair. I was still skeptical, but took him off. His symptoms immediately got 100x's worse for a week. But funny thing is, his headaches are gone, his stomachaches are gone and he seems much less emotional. The strangest thing is, EVERY night, he comes in to kiss us good night 7 or 8 times, and sometimes by the 7th time he is crying and can't explain why. This has been going on for YEARS, EVERYNIGHT, never a break. It stopped! Just stopped cold 7 days ago. Comes in once, says goodnight, leaves and falls asleep. I know this isn't a coincidence. After years of wondering what's wrong with my kid, now I feel like I've been poisoning my him for 7 years. I'm not skeptical anymore.
