Singulair and inhaler

I have been taking singulair for about a year and a half. Honestly I have had no side effects. It works great for me. I have tried to just take my zyrtec for my allergies without the singulair. I notice that if I don't take the singulair I feel shortness of breath and have to use my inhaler. When I combine singulair with my zyrtec I don't even need my inhaler at all. I was reading some of the experiences from other people, I think maybe children shouldn't take singulair at all.

I was on Singulair while pregnant because my asthma got worse while pregnant. Postpartum I noticed my 2 month old breastfed baby was still sleeping way too much and very colicky. I tried cutting out dairy and other allergens but nothing made a difference. When I forgot to take my Singulair a couple days in a row, I noticed my mood was much improved and the anger/irritability went away. Finally, after noticing I was having vivid, bad dreams, I began to realize it might be all from the Singulair. I also had developed a stiff, tight neck and vision loss, which I now realize was also from being on Singulair.
I went off of it and must say, that was the worst week of my life. I never felt so horrible or out of control. Although I noticed the first few days, I was happy and feeling again (it made me emotionally numb) by the fourth day, I began having heart palpitations and bad headaches. I quickly got my thyroid levels checked and those were fine. Then I suddenly had severe panic attacks! I thought I was going crazy! This was mistakenly misdiagnosed as PPD, although I was never even depressed. I was given a script for Zoloft and took Ativan but that didn't take away the panic and the Zoloft seemed to make the panic worse!
I began researching and realized all of my symptoms were from Singulair withdrawals! Even my family noticed I became a mean and hateful person with this last pregnancy. This drug is an awful poison! I am slowly recovering and feeling better everyday. I'm using my fast acting inhaler for the time being. Instead of the therapy I thought I needed for PPD (mis dx'd obviously) I'm also using herbs to treat this homeopathically with a natural doctor since conventional ones still want to pass it off as something it is not due to ignorance that an asthma medicine can wreck this kind of havoc on a person! They just want to use more drugs to treat the side effects of another drug!
I am so angry I took this while pregnant and breastfeeding being told it was okay. It was not okay and I hope and pray there are no long term side effects to my child from this drug!

My boyfriends kids 8 and 6 have been are on Singulair, Advair, Pediatan and Veramyst. Both daughter and son experience restlessness...trouble sleeping, stomach problems, Headaches, daughter especially experiences anxiety and mood changes. So many symptoms I have seen posted here. They have been on these meds for years and take them all every day....I am printing posts and researching info for him to give to his ex to find alternative treatment for their allergies and asthma....any advice or info will be greatly appreciated.
thank you!

My son was on singular about 4 years ago and i thought i noticed irratability, lack of interest and depression, but he was only 4 1/2 at that time and i couldn't tell. It did relieve his allergy symptoms. We took him off at that time. Now, again put him back on it this past year (he is now 9 years old) and i see again a lack of interest, depression, mood swings, irritability and his teacher just told us that as this year has increased he has changed in his school work as well. As of last night we will be taking him off of this medication for good and will continue to manage his seasonal allergies with an emergency inhaler and zyrtec/claritin type meds. He is sluggish on the baseball field and not as alert (he unusually a natural athlete!) and he seems depressed and withdrawn - which is not his personality. I thought maybe because he was getting older he was changing but now I realize it is again the medication. It is okay for a week or two to get through a cold or high allergy week, but long term I will not have him on this any longer and wish that Merck would make the long term effects clearer to the doctors, patients and public in general. We are fortunate that his allergy symptoms are not as severe as other children and we can go lightly on medications.

I am 39 years old and very active. I have been on Singulair for about 2 years now. I did not think I had any problems while on the medication because it did help my breathing. I am now on an antidepressant (Lexapro)which I began about a year after I began the singulair. My depression however started almost a year before I actually got on the Lexapro. I had alot going on in my life so I just equated my depression to that. However I am realizing now that maybe the singulair triggered my depression. I ran out of singulair two days ago and am experiencing withdrawal symptoms, extreme tiredness, stuffy head, and I had heart palpitations last night, which I have never had. The withdrawal symptoms are why I began researching the medication because I couldn't understand how being off of it for such a short time could cause such an effect. I was on Singulair once before about 6 years ago before I retired from the military while I was at Ft Hood before I deployed to Iraq. By the time I left Iraq I was on multiple medications, Singulair, Claritin, Advair, Emergency Inhaler, When I arrived in Iraq I became ill and listed my medications. They were in shock and took me off everything except Claritin and I was fine. It wasn't until I returned home I began the Singulair again. (Why? I guess I never equated it to causing my other issues until now), I am also taking Zyzal and Lexapro. I see now that every time I take the Singulair it leads to additional medications to other things. I am going to stay off of it and hopefully be able to wean myself off of the Lexapro as a result. Unfortunately I probably will still need to take an allergy medicine. Thanks everyone for posting this useful information. I have two kids 6yrs and 12yrs and I know now that they will never take this medication. They have allergies like me so it is very probable that eventually it would have been mentioned. The allergist/asthma doctor is adamant the 12 year old has asthma but I never gave him the advair that he wanted him to take because I did have side effects from that medication that I did recognize myself and my son is the fastest runner on his select soccer team and extremely athletic without it, no emergency inhaler needed or anything.

April I started Singulair last Thursday night and felt tired and depressed
29th on Friday but thought it was something going on in my life. On
2009 Saturday, I had severe, throbbing headaches all day but took the
Singulair for the third night. Sunday, I again had throbbing head- aches so looked up this web site and thought, "Aha!" I stopped
the medicine but had dull headaches on Monday and felt tired. On
Tuesday, I woke up and had trouble breathing. I went to the doctor
who ended up putting me on a nebulizer, giving me a shot of
steroids and prescribing an inhaler that I'm to use 3 times a day as
needed until the Singular is out of my system. I was only put on
the Singular in the first place because my doctor thought my
hoarseness might be from an allergy. What a nightmare!
I also suffered from apprehensiveness, and also
sleeplessness, and a fever. Never again!

i am really glad i found this site, and got to really understand what may be my problem. its the SINGULAIR, i really believe. i will share my story so no one has to go through what i have been going through. (i just stopped my medicine a day or two ago, so i will repost and see if i start seeing changes in my behavior) well first off i am 19, and i started taking singulair when i was a senior in high school, so about 2 years ago. i didn't see any noticeable changes for awhile, except for probably a year now, a little more or a little less. for this whole time, i have not been sleeping, i wake up 3-4 times a night, fully awake and can never fall back asleep for hours. its almost like my body tries shutting down, but my brain never does, i have the craziest dreams, most of them are me suffocating or not getting enough air, which are really scary. I have been having really bad anxiety, panic attacks, basically i have been just feeling like i am going to die every second of the day. the feeling of being trapt inside my own body. it seems like every month it just gets worse and worse. i cant focus, i don't go to school, i don't work, and i believe its from the side effects of this medicine. i also always feel so tired, and so weak, i cant even look through a clothes rack without my arm aching. i have been having a hard time breathing, which is odd seeing its supposed to help me breathe, i have been sick at least once a month, through this whole time i have been going to my Dr. at least twice a month or more, telling her my symptoms, i even went in their one day crying i was so scared. and she just kept telling me, its probably all in your head, this, that and the other. she even put me on probably 10 different medicines trying to see which one would help. and of course none of them helped anything. I started thinking, and feeling like i was going crazy, what was wrong with me? i wondered constantly. For a couple months now, i figured i had to take it into my own hands to figure out what was wrong, seeing this Dr. doesn't seem to understand me. I looked up every disease or problem imaginable, and had blood tests done, but every thing came back normal. i didn't understand what was going on, every month i just feel worse and worse, lately i have been telling my mom i just want to die, that i cant keep living my life this way, of course i would not do this for the fact that i couldn't do that to my mom or my little sister, or anyone, but it feels like it would be easier then dealing with everything i have been. along with everything else i was/am feeling, i also feel a lot of hate toward myself, i feel like i am not good at anything, and i feel very ugly, sometime i don't even want to leave my house, because i just feel disgusting. Finally, a couple days ago, my little sister which is 10 and really smart i may add, was watching TV and they happened to have a commercial for SINGULAIR. she told me that everything i have been saying that was wrong with me (she hears me complaining a lot about all my problems to my mom) were all the side effects from SINGULAIR. of course i wanted to know more about this even though i have taken this medicine for awhile without any of these problems, i started researching and realized that all of my symptoms happened to be the side effects from singulair. and then i started reading other peoples stories about it, and about linking it to suicides and everything. i told my mom and i told her i wanted to stop the medicine right away, at least just to see if this is what it was all along. i haven't taken it for 3 days now i believe, and i already see a difference, i actually get tired now instead of staying up reading till 5 in the morning, and i haven't been waking up at all during the night. i am pretty angry that my dr. couldn't figure this out, or at least maybe even think about it. for awhile i thought i was honestly going crazy, i lived in fear for so long that something was extremely wrong with me, that i haven't lived my life the way i should of, or wanted to. i never thought that it was just the EXTREME side effects of this medicine. i am so thankful for my little sister listening to all my complaints and all my anger toward myself, and actually putting it together that it would be my medicine that was supposed to make my asthma better. as i said its only been a couple days and i already feel better, i will repost to tell you if im back to my "normal" self after being off this medicine for a longer period of time. i feel so grateful for my little sister, who would have guessed she would tell me what a Dr. couldn't even think about. i really feel that if i get back to my normal self, i really have her to thank for saving my life. <3

I am a 49yr old male who has had asthma all his life, Inhalers made me hyper, steroid inhalers caused bleeding in the nose. My asthma was triggered by cold air(I live in the northeast) dogs, cats, molds mites etc etc. Nine years ago I started Singulair. It changed my life for the better. I no longer even carry an inhaler, very few times will I use a pulmo-aid(sp) for fast acting relief from asthma. Sometimes I have leg cramps and some other side effects(very few). Everyone responds differently to medications.
Singulair has had a positive effect on my life. Parents!!..It's hell to see your children go thru sickness. It was hard on my parents as well. Good luck and find the doctor who will be patient with you to help our kids.

Daughter just turned 2, started Singulair on her birthday, so it has only been 9 days. Already it has had such a positive effect on her reactive airway disease (a.k.a. asthma). In January, she had maybe a one-week break from constant runny nose, bad coughing, and 2 a.m. Albuterol treatments. Right after starting Singulair, she got a sniffle--which has always led to bad coughs, etc. But this time she dodged it.

About the same time, she has become more resistant to naptime. She used to just lie down and go to sleep, but lately she stalls and complains--like a typical 2-year-old. Of course, she was probably exhausted from coughing all night! Lately she'd been sleeping 7 pm to 8 am and then napping noon to five!

If it makes her only slightly more intense, I'll take that over worrying whether she's going to suffocate in her sleep. But, having read these comments, I will definitely keep a close eye on her! Pediatrician suggested we try taking her off it for the summer, and back on for the fall/winter.

I am 39 years old. I was prescribed Singulair last month. I have bad allergies and have started to develop some asthma type symptoms. My doctor decided to try me on Singular before giving me an inhaler. I took the Singulair for 2 week and had to quit. After the first day, I developed a headache that would not go away, nausea and very vivid bad dreams. This lasted the entire two weeks that I took Singulair. I thought that after maybe a week, some of the side effects would go away but they didn't. So, I quite taking the stuff. I will never take it again. I am back to my Zyrtec for now.

I was given Singulair a week ago when I went in for bronchitis. I have noticed I do stay tired all the time & that I've become more disconnected from emotions. I am normally a very sensitive person, and it's not that its been an extreme change, but the change is there and I don't like it. I also have had to continue using my inhaler due to tightness that the Singulair does not completely get rid of for me. Yesterday, I was having dinner when my head just spun. I grabbed my composure and was ok as long as I stayed more relaxed & didn't talk a lot. I have terrible allergies and I knew that my bronchial tubes were constricted very tight & that was the cause for dizziness. This morning, my lips were starting to swell and I was starting to feel the puffiness in my eyes. I wanted to know if I could take benadryl w/ Singulair & came across this site. I took the benadryl I feel much, much better. Seems to me that if Singulair is supposed to control the tightness I would be getting better, Not worse. I have made up my mind to stop the Singulair & will contacting my doctor for something different to help with bronchial contrition.

Thank you all for sharing your experiences.

My wife (66) was using salbutamol inhaler for the last 10 years being a bronchial asthmatic. Even prior to that, she was being treated with a combination of theophylline, cortisones . In 2001 she was diagnosed to be suffering from OCD and citalopram 20 mg was prescribed. With significant improvement, the dosage was reduced to citalopram 10 mg, though we lowered the dosage only in December 2007. However, during the last month, when she had to be admitted in the hospital for a stomach virus the doctors prescribed MONTELUKAST SODIUM 10 MG combined with lEVOCETIRIZINE 5 MG. .
Dramatically,montelukast had a dramatic effect in that my wife never used the salbutalmol inhaler for well over 2 months, about which we were very happy.
But the worst was yet to come.
During the last few days, she again showed symptoms of the dreaded OCD once again, and she suffered like anything. On contacting a well known doctor, we were advised to stop MONTELUKAST and asked to continue citalopram (though escitalopram instead of citalopram ) along with clonozepam 5 mg to be tapered down every week for about a month.
I would like to be advised from a doctor whether (a) discontinuance of Montelukast will be able to bring back normalcy from OCD of course with citalopram or escitalopram. and (b) whether montelukast can be abruptly stopped. For the time being, we have reduced the dosage of montelukast from 10 mg to 5 mg.
PLEASE ADVISE US.

I wrote a post few days ago about Singulair and how great my daughter is doing since she started to take this medication three months ago.
Then I started reading about all the side effects that other children had because of Singulair. I GOT SO SCARED!
So scared that last night I stopped giving Singulair to my daughter.

From January to September my daughter had asthma every other week. She was put on steroids (prednisolone) every time she couldn't breath. Then in September the pulmonologist said we have to take control of the situation because so much steroids can damage a little body.
She made me feel I had been a terrible mothers since I always refused to give her singulair.
She convinced me and then I started Singulair, but now I feel worst because I have the feeling I am giving poison to my daughter even if her asthma is under control.

My 7 years old stopped Singulair 12 hours ago, I do not know what is going to happen now. Of course I cannot call the pulmonologist anymore in case my ds gets bad.
Somebody here said that she is giving her son Nordic Naturals Fish Oil, Culturelle probiotics, vitamin c, and changing his diet - increased magnesium and decreased dairy.I will love to have more information about this alternative way of controlling asthma. I do not remember who wrote this post. If there is a web site of a doctor I can contact i will do right away. I live in New York.

I need help. Thank you so much.

I have an 8y.o. daughter that has been on Singulair for about 3 years now. Since she started taking singulair she has been absolutely miserable! She cries at everything, is very moody, has leg pains, wont leave my side and is tired ALL the time. She has circle under her eyes, she looks like she hasn't slept a wink in days! She has been off her Singulair for about 5 days now and she is a totally different person. She has been "happy-go-lucky" and full of herself, she has even woke up happy (which hasn't happened in I dont know how long). She was put on Singulair by our Doctor b/c she had Pnemonia two times in a row. She has Allergies and Asthma and for the past 3 years has been on: Singulair (4mg), albuterol, flovent, Zyrtec, and Flonase. That is just too much for a little girl to be on. She hardly eats at all, gets headaches. I just see such a difference when she is not on it but, what will she take in place of this? My husband also takes Singulair (he is miserable all the time), he doesnt sleep at night and is always tired. Anyone have alternative to this drug?

I am a pediatrician and my and I take care of my one year granddaughter is with allergic rhinitis and bronchial asthma. In her past history other than her usual problems she developed an episode of ketotic hypoglycemia after a viral syndrome.
I started her in Singular as she was having nocturnal episodes of cough in spite of having Pulmicort twice daily. As soon as she was started in Singulair she developed restless episodes of irritability. She never behaved that way before. She is now sleeping well all night after she had discontinued Singular.

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.

My 3 year old is on 5mg of singular daily for her constant allergy issues and has had NO trouble at all with it. Her personality has not changed.. she's happy, outgoing, friendly and MUCH better than she was before she started the medication. Prior to starting she was constantly dripping from her nose, she had both ears filled with fluid, had bags under her eyes and was tired and grumpy all the time, due to allergies we could not get under control with other over the counter or prescription meds. Since being on Singulair she's been 100% better than she was. I'm sad to hear that others are having so much trouble with it, but I can say that I am happy my little girl is feeling better.

I was surprised to hear that Merc, the maker of singulair update their side effects 4 times in one year to include depression, anxiety, suicide, and suicidal thoughts. It was prescribed to me cos of my allergies and asthma. I never really took singulair on a daily basis because it made me feel so tired and out of it. So i would only take it when my allergies were very very bad, like having a bad sneezing fit or nose would be runny non stop which would be at least 1 to 2 times a month. My asthma wasn't really that bad, i would get it when my allergies would act up like i mentioned before. When the fires in California were going on my asthma started acting up because of all the ash in the air. I was having asthma attacks every day. Since singulair works great for asthma i started to take it everyday and noticed my asthma went away. The first couple days were fine..and after two weeks i started noticing i was becoming anxious and irritable. Also depression sunk in...So i wondered what was causing it. I wasn't going trhough any major life changes. So i looked up singuliar side effects and noticed the four new side effects that i mentioned above...I stopped taking the pills to see what would happen and i felt emotionally better but the asthma came back..id rather suck on my inhaler then be anxious and depressed.

My daughter is 7 and was just put on Singular as a preventive medication for croup which she gets when she has an infection. She is not on a daily inhaler nor does she have asthma attacks at school. I asked the doctor for an alternative to the pulmicort breathing treatments b/c the prolonged use of this caused her to have dental issues (8 cavities) and he gave her singular. I am concerned of the side effects in the reviews of this medication but I need some relief for my child. She has been on the medication only 1 day is frequent urination a side effect and can it come on that quick? If there is another medication that doesn't have the side effects apparently singular has please let me know.

I am so thankful I found this site! My 4 year old son who suffers from asthma & allergies was just prescribed Singulair on Tuesday 10/21 along with Pulmcort inhaler & Xyzal.The doctor said to give him these daily for a month due to it being Fall. I do not like the idea of him being on any drug let alone 3 at one time. So today I started to do research on them. I will NOT be giving him the Singulair ever again!! He only had it the past two nights. He only had one pill on Tuesday night and by Wednesday night at his basketball practice he was saying he was tired and laying on the floor...this is so not like him. I believe it probably was from this medicine already having an effect on him. I am glad I found this site before he started to have these horrible symptoms that so many innocent children have had. I am going to call his Doctor and ask for something else to give him. What have doctors prescribed for your children in place of Singulair????

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 8 yr old has been on singulair since May. I never put two and two together until reading these posts. He has been having anxiety at night..crying and looking terrified saying he can't stop the scary thoughts in his head. Tonight I felt so bad for him...because I can't make it go away. I am hoping with tonight being the last night on singulair he will not have such a hard time at night. He also says it's very hard to get to sleep at night. Poor kid. I also know he's a sensitive kid but it seems a bit overboard in the last few months....like getting upset and just not knowing how to handle his emotions so he just shuts down. Please message me if you've had similar experiences. I'm calling his dr. on Monday to figure out some other options if there is any. My son started with a cough in March and finally took him to see the dr. in May and she heard wheezing and started him on singulair and then added zyrtec. I know they control his coughing (wheezing...slight asthma) because if we miss a dose he coughs all day the next day. I'm a bit scared to go off it...but hope it stops the anxiety and moodiness. He had his first asthma attack last week too...and I wasn't prepared as we never have had to use the inhaler...so I didn't have it with us. Anyway, hoping he doesn't get too bad taking him off...and I hope he is able to control the scary thoughts by going off of it too.

for the people that have taken their children off singulair...
what are you using for a preventative med?
my daughter has really bad asthma and I don't know of any alternatives

This past winter we found out that my son had developed asthma. His allergist /asthma doctor put him on Singulair as his preventative. Not two days later a report came across the news that Singulair has depression as a side effect. I immediately called my son's allergist / asthma doctors and was told that these symptoms have been found ONLY in children in their teens. That they are linking something in the med with hormones and it spawns depression.
Even though this is terrible for the parents of teenagers, my son is 6 years old... the chance of this happening to us was slim. Or so I thought.
One morning, to my horror, two weeks later my 6 year old son whom never really watched anything on television without his parents (with the exception of Noggin programs) is talking about how he wished he was never born. That no one would care if he was to die or disappear. That maybe he should just go to sleep one night an just die..... he was getting so angry for no apparent reason, throwing things and yelling all the time... telling me, his mother (we have always been so close) that he wished I were dead and that he hated me...
Needless to say I immediately called his doctors and they told me to stop the Singulair right away. The doctors were shocked that this has happened to a 6 year old and had filled out reports for the FDA that I had to give detailed descriptions of what happened to my son so they could start warning other parents.
Now, four months later and we have our happy go luck son back. No preventative, but the inhaler is doing the job.
Good luck out there if you agree to put your child on this medication. I understand it does not happen to everyone, I just cannot tell or describe to you how horrifying and traumatizing it was to go through seeing my happy go lucky son become this extremely depressed angry aggressive child within two weeks. We are still battling the aggressive behavior, but hey, he is 6 and that could be normal... right?

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.

I am happy I found this website to express my concerns about singulair. My husband and I are still shellshocked about how singulair turned our lives upside down. My son was on singulair for 5 years. During that time he had extreme anxiety, nightmares, stomach aches, suicidal thoughts and tendencies, difficulty in school, aggressive behavior. We were at our wits end when we sought therapy at an anxiety clinic a year ago. He never went on any antidepressants or anti anxiety pills, just behavioral therapy. He went to therapy for approximately 5 months once a week. At the time he started therapy, I happened to switch doctors for his asthma due to an asthma flare up. He went to a pulmonology specialist at CHOP. He was taken off of singulair and put on other inhaler medications. Slowly, we began to see improvement in his behavior. I was holding my breath, thinking I was imagining his improvements and hoping his symptoms would not return. My son is now 9 years old and has been off singulair for one year. His horrific symptoms are gone and he no longer needs therapy. He is a happy, active nine year old. He had a successful year in second grade last year. I never realized it could have been singulair that caused his symptoms until I heard it on the news. His symptoms were always related to "behavioral problems". It was such a heart wrenching, frustrating experience because we could not figure out why he was behaving this way. My heart goes out to all the families who have experienced devastating symptoms. I contacted merck and the FDA. I want to contact my state representative. I am looking forward to seeing the results of the FDA study. I am curious how they are obtaining their data because I was never questioned about the details of my experience.

I just read an article dated 9/1/08 that stated that the American Lung Association just cleared Singulair as causing depression and suicide. They had researchers study the results from the original test trials because they are supposedly more accurate than after market reports. The article is at ******. I cried when I read this report. My now 8 year old daughter has been on this medication for mild asthma since she was 4. We have thought the stomach aches and tantrums were related to moving to a new town around the time she started taking singulair. But, 3 months ago, she all of a sudden started having depression, ocd about germs, afraid she might hurt herself and then depression and suicidal thoughts. She has been off meds for 8 weeks and still has some problems with thinking she wants to hurt herself and feeling down. She is normally very happy and our family is happy and normal, but dealing with this is difficult. How long does it take to get out of their system?

After taking a "leave of Absence" from this site, I see that Singulair is still up and thriving. I still see ads for it on TV, over and over again. They haven't been altered at all. Makes me sick. I wish there was away to get to other people whose children have died by suicide and investigate as to whether or not they were ever on singulair. Keep fighting. We'll get there! Kate K

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

Have been experiencing the same serious behavioral issues (screaming, launching every toy he has out of his room, knocking over his night stand, hitting, kicking and just being hateful) with my 4 year old who has been on Singulair for 2 years as I'm noticing many of you have here. My wife and I have a wonderful relationship and happy home and tons of love and support from other family that's close buy so the kid has a very nice environment. We have taken him off the medication as of yesterday. I have consulted his doctor but I'm anxious to hear what methods of treatment for the asthma all of have chosen in replacement of Singulair or did you just maintain with an inhaled maintenance program with something like Pulmicort? Also, how long was after taking your child off of Singulair did take to for the outburst to subside and the behavior to become more mellow and normal (what is normal for a 4 year old?). Any info would be greatly appreciated.

My 10 year old son has asthma. His inhaler is not working so the Dr. put him on Singular yesterday. I had him take one right when we got it. I then dropped him off at a friends house. Around 2pm I picked him up. He fell right asleep when we got home. He woke up crying. He proceded to cry & be totally unreasonable for 5 hours (until bedtime). He told us he didn't want to play football & he didn't like it (this from a kid who lives for football). He then proceded to call his coach & quit football. We tried to console him but there was no consoling him. This was all after being on it for less than 12 hours. I think the only reason we noticed this dramatic change in demeanor was because his is normally a very good kid & he instantly became uncontrollable. I then called his friends mom & according to his friends older sister he was 'out of it' for most of the time he was there & kept asking the same questions over & over. Needless to say he will not be taking another Singular pill! I have notified my son's Dr. of this & hopefully they will report it to the company.

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

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

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

PRAISE GOD for all of the stories shared on this site. And I've only read page one. My husband called me back today to say that he "googled" Singulair and found some interesting things (to say the least). While we were on the phone, my three-year-old was in the throes of another meltdown, kicking me, hitting me, throwing whatever he could get his hands on. My older two boys, 8 and 12, were ordered, once again, to lock themselves in their rooms to avoid being hurt by him. He will throw stuff, bite, hit, kick, and, at times, spit on us. This disturbing behavior is rather constant lately. He is like a mad man. Very scary.

Caleb has been on Singulair since about age 1, when he was diagnosed with chronic sinusitis and allergic rhinitis. Unfortunately, we initially equated his rages with the onset of "terrible two's" and dismissed his behavior to a chorus of "oh, he's just a boy!" My husband felt, at times, that I was just not disciplining him properly. I intuitively knew, having raised two other boys, that this behavior was abnormal, even for severe tantrums. We received a variety of suggestions from his pediatrician, caregivers, and grandparents, all to no avail. We have several calm days but things always deteriorate back to insanity. He is VERY unpredictable.

Last Thanksgiving, Caleb (age 3) was kicked out of his daycare setting for biting and hitting. Once I witnessed him run as fast as he could into a group of playing children, falling on them, kicking them. He would walk up to sweet little girls half his size and push them down as hard as he could. It was a nightmare. My husband had to take 3 weeks of leave to stay home with him while we prayed and searched for new care. We had him evaluated and he was staffed into the "developmentally delayed" program in our school district (for poor adaptive skills and personal/social behaviors). We recently had his tonsils removed, hoping that some of the sinusitis symptoms and behaviors would improve. They really haven't. This past week we have been looking into the Feingold diet. We have been PRAYING for answers. The last time we spoke with his developmental neurologist, he recommended a trial of Risperdol (sp?). We feel like more meds would be like a band-aid, not a solution. But his rage is becoming unbearable.

So, that brings us to today. I was so moved by your accounts. Unlike so many of you, we don't have much of a "before" to go by. But his "after" sounds VERY much like what you have all described. It's probably the pure rage that I see on his face that is the scariest part. And at the same time he seems desperate and vulnerable. He truly seems to snap. If we had pool chairs, I can just picture him throwing them (citing another post :).

We are going to throw the Singulair away. He will never, ever have it again. Even if this isn't the cause of his problems, I certainly don't want to exacerbate any behaviors with this toxic medicine. I will post again just to let anyone who's interested know if this changes his behavior. I am praying that my entry will help someone else, just as all the other postings have helped me. I have renewed hope.

I have copied many of your comments to a Word document. I will be sharing it with a high ranking officer at the medical clinic/hospital on Keesler Air Force Base. I hope that he will discuss this with his staff and that perhaps we can at least make a difference here. I, too, will be filing a report with the FDA. I can only pray that this medicine has not permanently altered his developing brain.

HI,

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

I am a 50 year old women. I had bronchitis that turned into severe asthma.
Could not stop coughing. I have been on Singulair for over a year. Have had weight gain, Hand numbness,Stomach problems. Even had an colonoscopy but turned up nothing. Now I understand after reading all these posts. The weight gain alone was driving me crazy. Limiting myself to 1200-1400 calories, eating only lean meats and vegetables.Exercising and loosing MINIMAL weight over a 4 month period. I felt like I was doing something wrong. Ive thrown my Singulair away after reading your posts. Will figure out something else if my allergies and or asthma flairs. Just not worth it. Will repost after Ive been off a while.

(A divorced father)
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.

My son is 5 years old. He was put on Singulair in August following a case of pnemonia. He has asthma. I found it worked well since I was barely using inhalers anymore. His eczema was even getting better. So I was happy with the medication. He also seemed to be getting more agitated with us. At least three times a day he would have an outburst towards his brother or us, like he was going to punch or hit us. Then I would say "why are you mad at me" and he would say "I'm not mad, I'm frustrated" and then burst in tears. He was getting a lot of time outs. Then two months ago he started saying "this is not a good day" or "this is a sad day". I was wondering if singulair was to blame, but it wasn't until I heard concerns from other moms. I took him off it as an experiment and noticed the next day was without his outbursts. Then I just never gave him anymore...and I am relieved to say he is as "normal" as I remember him before Singulair!!! He also was unable to get to sleep easily on Singulair, sometimes 1, 2 and even three hours to get to sleep. Now he is out in 20 minutes if not less. I haven't talked to the Doctor yet. I have noticed his eczema is flaring up again and he has used his inhaler this week (although he has a cold). I think I can deal with that without Singulair and the problems I am suspicious come from it's use.

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

I have been Singulair-free for 11 days now. I do not entertain any more suicidal thoughts, I feel MUCH happier just generally. I have cried, but haven't felt really low, just sad, normal-sad. I do have more difficulty breathing and tightness in my chest, but I am looking into adopting an anti-inflammatory diet. I have exercised more since stopping the Singulair, so I hope that will help long term with my lung function. I would definitely say I would rather feel some tightness in my chest or breathlessness going up stairs than intense sadness and irrational suicidal ideations. This life is much better than the one I had two weeks ago, and I know it's the same life, nothing has changed, just my perspective. I wonder if taking drugs off the market is going to be like putting up stop signs or traffic lights - we have to wait for a significant number of accidents before that move would be warranted. I really can't believe that all those years I thought it was me. I am a whole new person psychologically and it is because of an asthma medicine that is approved for KIDS! Amazing.

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.

UPDATE: Our nightmare with SINGULAIR has not ended! After reading "conerned citizens" report discussing the possiblility of Singulair causing asthma blew me away. My son was put on this drug for food allergies not asthma b/c they thought of his two anaphylaxsis episodes in 5 days. 1 food related the other unknown (maybe outdoor mold?) He had no prior issues with breathing.

He has been off of it for almost 2 weeks however over the last week he has slowly developed some breathing issues. After getting off of it, he still has his ear infection from the second day of being on it and last Friday after playing some basketball began to seem like he was winded so I brought him in. He was having trouble breathing. I called the Dr. and he said it could be excercised induced asthma. He is a very active boy who runs non stop and has NEVER had breathing issues before Singulair! It seemed to pass after a few hours. The next fews days he coughed a few times when playing and I thought what the heck is happening to him. Monday at school they didn't go outside so he was fine b/c he didn't run around. Tuesday, they came to get me b/c he was having trouble breathing and one of his teachers whose son has asthma said I think you better give him an inhaler. I called the Dr. ASAP and he approved us to borrow another child's. He freaked out and wouldn't let us give it to him. After 2 epi-shots in the previous weeks, he wanted nothing to do with that. At school the next day, we made him take the inhaler if he wanted to go out to playso he did. He didn't cough but a few times. No excercise at all. Then last night, he got really bad. He started to cough and couldn't stop to the point of gaging and it seemed as though he had developed a ton of phlem and kept trying to swallow. We ended up in the ER where we were told that he has asthma! I am so furious! I don't get this at all! If this report is accurate and my son got asthma by going on it - this will be devastating. We kept him home today from school and took him into the Dr. b/c he continued to cough all night. He is now on Flovent, Albuterol and has an enebulizer. I'm probably the only one of all of us who child did not have asthma to begin with.

Has anyone who did not have asthma before singulair now have any issues? Please let me know!

Update...Today is the 11th day my 7 yr. old son has been Singulair free! He was taking it for "cold induced" asthma. He never had the typical asthma where he needed an inhaler. He got RSV when he was almost 3, then whenever he got a URI it seemed to go straight to his lungs, so the dr. prescribed Singulair and Xopenex (to be used with a nebulizer). I had asked the dr. a few times to take him off Singulair because he seemed to be doing much better and I wanted to see how he would do without it. The dr. would say "oh, let's wait until summer or let's wait until allergy season is over" and kept putting it off. I just had some sort of bad "feeling" about it. Of course, I look back now and know with certainty that his wierd behaviors started around the time he started Singulair. I am relieved now because his erratic behaviors are almost totally gone!!!! When I heard the news I decided to take him off the Singulair immediately. I was nervous because he had a cold and a bad cough, but did it anyway. You know what? He is fine! His cough is almost gone now without the help of Singulair! He is much happier and can actually focus on doing his homework without getting up from his chair until he is done. Before he would get up about 10 times and just couldn't sit still. He has a better attitude about everything now! He is doing great! I hope everyone who was taking this and stopped is doing better! I learned a valuable lesson from all this. I won't put him or my other son on anything until I research it! I will not trust anything anymore, and that in itself is sad, but true. Good luck to all!

I am one of many that has decided to stop giving my child Singulair. And like many others, I have noticed a great improvement in her behavior.

My question is for those who have done the same. What medication have you replaced the Singulair with and have you noticed any of the same side effects that Singulair was causing? What are your thoughts on Flovent inhaler?

Any feedback would be greatly appreciated. Thanks!

Has anyone else that has taken Singulair for awhile tried getting off of it and noticed that their asthma was worse than it was before they started on Singulair? I'm a 29 year old male, been on Singulair for 2 years. After reading these blogs 2 weeks ago, I decided to see if I noticed any difference in my energy level, moods, etc after dropping Singulair. I didn't. But what I did notice during my week-long experiment was that my asthma was way worse. Prior to Singulair, I would only have to use my inhaler if I exercised. During the week that I dropped Singulair, I had to use my inhaler 5+ times daily because I was wheezing...especially waking up in the middle of the night not being able to breath. This never happened to me before I started on Singulair. In any event, I'm back on Singulair now to keep my asthma in check.

My daughter is seven years old. She was diagnosed with asthma when she was around two years old and, for years, suffered with the night cough associated with childhood asthma.

When Singulair came along, my initial reaction was that of joy. My husband and I could not believe that we no longer heard coughing throughout the night. However, while on this drug, we also noticed that she underwent a change. Sometimes, she seemed terribly sad and withdrawn. Other times, she became angry and even aggressive. We rarely saw her smile. It also seemed like she was in some sort of fog much of the time. About a week ago, I found her on the floor of our office. She had just gotten out of the shower, and I was getting her pajamas for her. The towel was not around her and she was shaking violently and crying. She explained that she had the chills, but it was clear that she didn't even comprehend that her towel was not around her. We all know our kids, and, I'm telling you that this scene was frightening. This was not at all my daughter.

In addition to the mental/emotional changes, she also had physical symptoms including sudden and frequent headaches, fatique, stomach pain, and bed wetting. A day after her "breakdown" in our home office, my husband called me from work and told me that he had just been reading MSNBC and that there was an article about the negative side effects of Singulair. When he listed things that matched what our daughter had been going through since on this drug, it was both comforting and horrifying. I am relieved to know that there is nothing wrong with my daughter psychologically, but I am furious that she and so many others have been treated like guinea pigs. We took out daughter off Singulair the very same night that my husband came across the article on Singulair, and she hasn't had any of the mental or physical symptoms that she had been experiencing...the change was that drastic. Currently, we are only using her inhaler and Benadryl at night. She has a doctor's appointment next month, and I will tell the doctor about our experience.

I have my little girl back, but I can't help but wonder how many families are going through this and do not have a clue that Singulair could be the problem. Other than reporting this to our pediatrician, is their another agency I should contact?

Good evening all....I as well as you all have a story to share about my son. Kameron lived the terrible twos to the fullest and turned into the biggest sweetheart when he turned 3. But then his doc wanted to try something stronger for his allergies and thats when Singulair changed out lives. Kameron has been on that junk since about November/December and since then everyones lives around him has been pure hell. He turned into satan in the flesh. I have never seen as much anger as I do in my son. On a weekly basis we go through stomach pains, depression, anger issues, him not eating for days, many sleepless nights, and thats not even all of them. He has spit in my husbands face and called me very bad words (that nobody has ever used in front of him towards me), Ive walked around with black eyes from him (remember he is only 3), he has given me bloody noses and straight up told his dad and I both that he hates us, and doesnt love us anymore. We cant take him around our friends children cause he is very abusive and controlling with them. He shows no interest in the things that he once loved, like his toys and pets. We have taken him to the doc and have been told over and over again that he is just a typical 3 year old but a mama knows when something is wrong with her baby!!I havent seen my sons precious smile since this stuff has taken over him or even heard him laugh. Im taking him to a different doc tomorrow and takin all of your comments with me and I am not leaving his office till they do something for my son!! My thoughts n prayers are with all of you that are goin through this cause I myself now how hard its been..

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

We've been searching and wondering for the last 4 1/2 years what happened that November night that our 15 year old son suddenly took his own life. This boy was a fun, loving, jokester that was loved by everyone he came in contact with. We always had a stream of kids in and out of our home. He had just gotten his drivers license, went to homecoming and played on the football team.
Andrew had been on Singulair for about 3 years. He would get the stomach aches, leg cramping, odd sleeping habits and moodiness at times, but we attributed it to a young boy going through puberty. He also experienced the shakes which we were told were from the inhaler.
We had no dramatic warning signs nor was there a note. It all happened so fast that evening. He walked out of the house and 10 minutes later he was gone. Our whole community was in disbelief and devastated.
After speaking with Miller's and reading many, many testimonies on numerous sites, We feel we may have our answer to our years of wondering.
