Behavior issues symptoms and conditions

My 10 year old son has taken Singulair on and off since he was 5 years old and has been on it for the past 3.5 years. My son at an early age was affected by a bad marriage and then the divorce when he was 5 yrs old. So we always suspected that his behavior issues were caused by this and I had done everything I possibly could to give them the help he needed to get over and through his issues. He was held back his first year of Kindergarden and during his second year midstream he was placed in a special class for behavioral problem children. Nothing ever seemed to help him, everytime we would see some progress and encouragement we were always blind sighted by a behavior that was always worse. Two steps forward and them 5 steps backwards. I always knew that his problems would never get better overnight so I just kept on going. He was diagnosed with ADHD but because he has some ticking issues I had to put him on Strattera which was did not do a thing for him. I always described him as my Dr. Jeckyll/ Mr. Hyde child. He could be really good and sit still and behave but I think he had to try really hard to do so. He eventually was always overpower by the impulse to show negative behaviors. Defiant, extremely impulsive, always negative and completely miserable all the time. He also went through phases of compulsions. There was always a compulsion of the month- germs, bathroom habits, noises, repetitive words. He hated school and always complained of a stomach ache which i thought he was always faking to get out of school. He had confrontations in school everyday for most of the day. I often thought some of this was because of being tired all the time. We had battled over bedtime every single night. He was terrified to go to bed alone, I tried everything to get him to sleep alone. I wore myself out falling asleep next to him, I would then go to my own bed only to be up with him half the night going back and forth. I gave in many a night and slept with him just so we could get a good nights sleep. At age 8.5 I finally got him to go to sleep alone but the lights haf to be on and he has to know that I am still awake before he will fall asleep. He would always say he didn't want to go to sleep because when he does he has bad thoughts about me and people that he loves. He always had an extremely hard time excepting the word "no"- he would flip out and hit his head with whatever was handy, throw things, break things, scream holler etc. It would take hours to get over it. When he did he would be very remorseful and lovable. He was always in turmoil. Finally in February of this year, this graduated to a new level where he would want to just kill himself and would actually go and pull a knife out of the drawer and just shake with anger as he held the knife to his throat. I was terrified although i really didn't think he was going to harm himself he just wanted to scare me. Then at the end of March when i first heard the news about the possible side effects of Singulair, I had only heard about the suicide effect. Oh great just what I needed was this medicine causing him to do that. The doctor was thinking about taking him off if this summer because he wanted to see if he out grew his seasonal allergies so I took him off immediately. Well I had no idea about the other side effects until my son turned into a completely different kid. School noticed a huge difference in him! His grades went up, his is able to control his behavior, he is happy he is NORMAL. I never suspected this drug as the culprit due to the timing of taking it. Our lives have changed completely. When i first found this site, it seemed as though some of the parents were writing about my child. It is amazing. My son still has some old habits to break but overall he is a wonderful and normal 10 year old boy. He did not outgrow his seasonal allergies but Allegra seems to help in through it. I get so angry- his whole early childhood was ruined by this medicine. He is a labled kid in our school system. This whole experience has opened up my eyes. Thank you for letting me share my story.

My daughter, just turned 3, was put on Singulair this past January for allergies. She had chronic runny nose, sinusitis, coughing, often leading to infections. The allergist put her on Singulair combined with Hydroxyzine every night. Now that I have read these postings, I recall that we had one really disturbing episode with her, although I can't now recall exactly how long after starting the drugs. Like some others have described, she woke in the night, seemingly terrified and at the same time in extreme pain. We could not find any way to soothe her or relieve her pain - she simply fought and flipped around, alternately reaching for us and kicking us away while screaming and crying and writhing on the bed. After a time, maybe half an hour, it seemed to just pass and she finally went back to sleep. But then we endured a couple of months of repeated wakings at night, sometimes when she was restless for an hour or more, sometimes upset. She might wake 3, 4, or 5 times in one night.

Lately I have become concerned about her increasingly aggressive behavior towards us, but recently towards others. And I am also very concerned about her physical growth. She is 41" and over 40 pounds and turned 3 a week ago. I am now buying her size 5T clothes. I have finally gotten proactive (why did I wait??!) and consulted with her ped., who has agreed that we should screen her for anything we can. My daughter has been diagnosed with developmental delays (pre-Singulair) and is in a preschool with similar kids. We have been dealing with behavior issues for the last year, and I am astounded that an allergist would put her on Singulair with the current controversy about it's side effects. I took her off it immediately as soon as I found out there were negative reports - thankfully our experience has not been as extreme as many others. But I feel ill at what could have happened! I am now praying that she has not suffered any irreversible damage...

Bless all of you in your struggles.

I have a three year old son who has severe allergies. He's been taking singulair for 2 years on & off just in the allergy season. He started taking, singulair again in the beginning of April. One morning he woke up and both eyes were really swollen and red, I called his doctor's office and told them i thought he had pink eye, after 2 different drops and no change I brought him into the doctor's to see if it could be his allergies, and they agreed and started him on Zyrtec. I still was not impressed with the results so i brought him back yet again to see if we could see a specialist. Instead they put him on nasonex to try.
In the beginning of March I started to see a change in my usual happy fun loving son. He was scared to sleep in his bed, waking up in the middle of the night from bad dreams, uncontrollable screaming fits that would last up to an hour, saying he wants a Boo Boo. At first we thought it could be jealously over his new brother, or maybe something at his school.
Then i found this website and everything clicked, how scary it must be for a child to have these horrible thoughts and not be able to understand or stop them. What are the people at merck thinking??
Can any one tell me when the symptoms stop. He's been off for a week and we see some improvements. But he still has these fits with almost an OCD tendency to them (mainly when he's overtired), stomach pains, lack of appetite.

In reply to concerned-dad and all others with chronic congestion, etc. I have heard several people that have tried the "Eat Right For Your Blood Type" (in bookstores) with incredible results. Even if they have not followed the most strict food do's/don't for their blood type, and made minimal changes they noticed a dramatic difference with congestion and asthma symptoms in children and adults.

I am not endorsing the book - but I will however give it a good hard try if my daughter's symptoms return that she had prior to being put on Singulair. And yes, you are so right to be concerned with the timing of Singulair and any new behavior issues - I still stand my ground when I say it is NOT normal for a toddler growing up in a loving home to have such horrible night terrors, screaming in fear.

My 4 year old took her last dose 3 weeks ago after a 2 year run on Singulair not an hour has gone by without her dad, sister and I still feeling waves of shock. She has completely changed from an unhappy, moody, unemotional girl into a loving, well-mannered, well-disciplined, even tempered 4 year old. Unfortunately, since the side effects have been so secretly held, all parents have been chalking all the behavioral issues to "toddler" years.

As I wrote to the FDA rep, this would be a classics Deceptive Trade issue for any other company in our country. Quite simply, when Singulair first rolled out it was sold with "ABC" treatments and "XYZ" side effects by the pharm reps. In February the FDA website notes they have given Merck 9 months to investigate (THEMSELVES) the many consistent complaints of side effects received for Singulair. And since the FDA did not give them a time limit to communicate the ongoing investigation and recently added side effects, my pediatrician and pharmacist as of May are still unaware. Same old commercials airing with the original "mild" side effects as sore throat, etc., same pharm reps visiting my doctor without informing of recent changes to the originally selling points.

Had my pediatrician been aware, I would have not received the answer I did when asking her what a toddler could have so horrible in their life to scream and cry through nightmares - "Some children react in their dreams if perhaps they saw a spider earlier in the day that scared them". I figured it would have to be a spider the size of my car to get that kind of nightmare, but in her defense had she been aware of the updated information with Singulair she would have zeroed in on the "bad/vivid dreams" Merck has now added to their website.

Hope this helps someone and if anyone has given the "Blood Type" eating regimen a try would love to hear comments.

My baby is 3. She had strep throat from Jan to April. I'm talking off the antibotic for max 4 days and the fever would return along with swollen glands, difficulty swallowing and just plain miserable. Took me 2 ENT referrals for someone to finally agree with me that this is not normal and something needs to be done. We scheduled a T & A for April 18th. The surgeon told me that she had a severe sinus infection as well (surgery day). He recommended that we start Singulair 4mg at night along with Nasonex to possibly help with her constant sinus congestion. I gave it to her and noticed nearly an immediate a change in her disposition.(looking back now) At the time I simply chalked it up to having her tonsils out. She was on the medication until Friday May 9th. Her babysitter said that she was seeing what I was at home...only I hadn't shared my dgtrs behavior at home with her...call it guilt for being a single mom who works...I just thought she was having trouble adjusting from a week at home with mom from the surgery recovery to getting back into the "norm" routine. At home she would cry at the drop of a hat. Not just wimper or whine....but tears and screams for nearly an hour. I would ask her why she was crying and she'd simply reply "I don't know Mommy." One minute we'd be playing and she's be laughing and the next she was angry and anxious. She would complain of "tingles in her feet"...I thought she had just been sitting on her legs and her foot had fallen asleep. She would deliberately instigate her older sister...totally not her. She became fearful of her room at nighttime...and took for ever to get to sleep. A co worker had mentioned that a little boy she worked with had his medicine changed b/c the dr said one of his meds may contribute to his behavior issues. Being a nurse I asked what med...SINGULAIR. I immediately went to the web and googled singulair. I found this site...and began to read parents horror stories of their experiences. She has not had another singulair nor will any of my children - EVER. I feel guilty that I didn't take the time to research it before I put her on it. I feel blessed that I was in the right place at the right time to find out about this site. I thought that my kind and sweet little girl had turned into. I know it's only 5 days off the med but she's back to her sweet self about 75%. I am blessed that my experience was not even a month long...but losing your child to a medication that no one warns you about even for a day is WRONG. I think I would be more "forgiving" if anyone along the line of me picking up the med had said ANYTHING...but no one said a thing. My prayers are with those who were not as lucky as I was to stop this med so quickly. I hope your children return to their pre singluair selfs quickly and permanently.

I discovered this site last Wednesday morning - without taking the time to list all of the grief I felt reading through the pediatric postings, I will briefly note my 4 year old daughter has been on Singulair for 2 years now. What I now realize is all the behavior issues, night screaming, etc. are so easily dismissed as stages of a toddler. She has suffered (as well as our family) every symptom and behavior listed by parents on this site with the exception of leg cramps.

Our entire family can see the dramatic results since taking her last pill last Tuesday night. The melt downs and tantrums are all but over, she even commented "hey, I listened right away" on the second day without Singulair. She is still having night terrors - I call them that because they are in no way a dream or nightmare, but rather agonizing moments that break our hearts to hear. I hope those will soon go away as well so her sleep pattern results in a restful night.

Am I angry that we have all suffered for 2 years only to find we have been basically poisoning her? Am I angry that for the 2 years her dad and I have sunk pretty low, feeling inadequate as a parent to teach and discipline our child? Am I angry that after 20 years of marriage, raising a great 16 year old in the midst of all this, we were to the point of the ADD, bipolar, etc. theory that would have been misdiagnosed? Heck no, we are all so thankful to have come across this site and are so giddy and excited to be happy again.

What I am angry about is this - when I called our pediatrician last Wednesday and relayed what I had seen on the Merck website for side effects added in recent months she had not heard this information and asked where I saw it. At that point I had not seen this site. I asked her how is it the well dressed pharmaceutical reps come in with doughnuts, exotic trips, etc. to market a drug with "ABC" treatments and "XYZ" side effects, continue to market the drug and never update the doctors when original selling points are altered - ie; new side effects.

The FDA website is troubling for two reasons: Merck is in charge of their own investigation regarding recent complaints and the FDA expects this to take 9 months. Gee, who gets to investigate themself? Secondly, in February the site notes the FDA and Merck are trying to find the best way to communicate the concerns being investigated to prescribes and patients. HELLO - we live in a world of real time, instant communication methods, two examples being the United States Postal Service and an internet connection.

Today is April 30 - a full two months after "trying to decide how to pass this information on" and my doctor, nor my pharmacist have received any information. Apparantly since we missed the story and coverage on Dateline we are out of luck.

I plan to start from ground zero to get our voices heard to change the way, or the law if you will, to implement an immediate communication link between the FDA and prescribes when an investigation such as this has been initiated. I realize Singulair has most likely benefited more humans than it has destroyed while on the drug and the FDA would have to clearly not communicate "panic". However, when a drug is used for pediatric treatments we need information quickly to assess on behalf of our children. In my case, since my daughter had been on the drug since 2 years old, I do not know what her "normal behavior" should be as that is the age they start to develop and show personality. Additionally, when enclosed prescribing information is updated with a prescription -MARK IT IN RED, "UPDATED INFORMATION". I read every ounce of information that accompanies a new prescription for any family member. I would NOT, however read the information every 30 days for an ongoing, long term prescription over the course of 2 years.

I am looking for anyone that may have started contact with a congressional representative or otherwise to change the communication to our doctors. Please note - I am in no way interested in any legal action regarding Singulair and our nightmare. We are moving forward and do not wish to live the nightmare one moment more. I simply want to see our doctors and pharmacists have vital information as it happens.

Thank you to all for sharing your experiences - I truly believe it is changing lives and making a difference. I am personally telling everyone I know about what is happening with our child and all of yours. Andy by the way, by telling one of my long time friends our amazing discovery, she realized she had been suffering from depression for some time and chalked it up to various things going on in her life. She had her last Singulair last week and feels tremendous! So keep the word going!

This is in answer to concernedcitizen. My son, when he began to have behavior issues, was placed on Tegretol, Wellbutrin, and Abilify. He could not tolerate the Tegretol. So he stopped that. His "depression" seemed better so they took him off the Wellbutrin, he continues to be on the Abilify. We tried to take him off of that once, it wasn't pretty. His anger, frustration, rage, crying, depression, etc all came back....of course he was still taking the Singulair. (little did we know then....) We see his neurologist very soon. I am going to ask about trying again to remove the Abilify. My son is 7. He was started on these meds 4 months after having surgery to remove a cyst in his brain....we thought all the problems were just who he had become after having brain surgery. It was very depressing. I read all of your research with great interest. I had thought it had to be a something in the brain being triggered. My son had a tendency toward these things due to the location of his cyst....we had the "luxury" of knowing he would have behavior problems. So did his doctors.... Now with all the research it would seem someone like my son, who has a cyst in the left temporal lobe (a region that controls behavior) should not have EVER been placed on a medicine like Singulair. At the very least, he should have been taken off that medicine, before being placed on anti-psychotics. Good Grief. Thanks again for all your work. I will be taking some of the literature with me to the Dr. As I am sure others on this board will.
By the way - My son has been off Singulair for 10 days now. He is a very happy boy. Downright giddy. He is annoying his sister to no end. Dad and I are enjoying every blissful minute.

My daughter is in kindergarten and has been on singulair for about 4-5 weeks. Her allergies are gone, no more snoring and and no more coughing attacks. My husband did ask the other day what was wrong with her because she had cried about 3 times that day. For any little comment regarding her older brother/ saying we loved him more etc. This is just not like her, now that I am reading this... I am putting two and two together. Does anyone out there know if Clariton will help with allergies as well as singulair?
I am seriously thinking of stopping the singulair.

I can hardly believe what I have read on this board. It is my son's story repeated over and over again and the sad fact is that I never put 2 and 2 together until I saw the news stories last week. My son has been on Singulair for years (he is now 7 years old) along with other drugs for asthma. We recently started taking him to a therapist because of his extreme unhappiness, violent temper tantrums, bad nightmares, many tics, and overall negative attitude. I took him off the singulair 5 days ago and cannot believe the results so far. My son is not affectionate in any way, does not even like a simple pat on the back, no hugs or kisses for sure. Two days ago he came over and gave me a kiss and a hug out of the clear blue. I cannot express enough what this meant to me. I have 3 other children that can't get enough of hugs and kisses, but coming from my 7 year old it just brought me to tears. The hugs have continued and he even told me that he loved me. The therapist had me convinced that he had a sensory deprivation disorder... until now. I cannot believe that until now I have not heard anything metioned in the news and that the medical professionals are so quick to dismiss claims against Singulair.
I am so thankful that I have found this website and for all of the people that have taken the time to include their experiences as it is evidence that there are serious problems when it comes to prescribing Singulair to children. I cannot help but to be saddened when I think of all the years I have lost to this with my son. All the time spent in frustration and tears over what I thought were serious behavior issues on his part. Not to say that I never expect any negative behavior out of a child, but certainly not like I have had to endure in the last years. The last few days have been amazing...I pray it continues. Shame on Merck for not being forthcoming and only keeping their bottom line in mind.

My son took singulair for over two years. He is now 9. Foe the last few years he has had a Jekyl & Hyde personality. Sweet as can be one minute then he will fly off the handle, calls us names, screams, breaks furniture. He also becomes emotional very easily. We have been baffled as out two other sons have never behaved in this way. I am now wondering if there is a connection with his behavior issues and his having taken Singulair for a long term.

I almost stopped my car on the highway this morning when I heard the 10AM top story on our local CBS news radio station stating that the popular asthma drug Singular has been linked to thoughts of suicide.

My son started taking Singular approximately 5 years ago (he is now 10). We noted almost immediately a change in his behavior. My son was normally a very mild mannered child, yet when taking Singular he started experiencing severe mood swings, rapidly moving from quiet and happy to fits of rage ending with him saying he wished he were never born or that he were dead. We told his pediatrician about this observed behavior change, but she hadn't hear of that reaction before. I checked the Singular web site at the time, but I don't recall mood changes being listed.

My son is still taking Singular because it has been so effective at managing his asthma, nearly eliminating the need for Albuterol. We haven't had to make any trips to the emergency room since he started taking it, and he seems to stay much healthier.

I will be having another conversation with his Dr. ASAP about whether the risks outweigh the benefits, especially since my child will be moving into the normally volatile teenage years. The last thing I want to do is complicate things by risking increased volatility from the use of Singular.

My daughter will be 2 in June and she suffers with asthma she has been taken diff meds such as xopenex, pulmicort, orapred, and now singulair. i researched all the other meds and took her off but the asthma specialist said she needed the pulmicort and i asked her pediatrician what he thought and he prescribed singulair he said it was completely safe and i had nothing to worry about but now i am very much worried because my daughter is only 21 months old and can not tell me exactly what wrong if anything. she has only been taking this singulair since last night so it has been twice she has taken it and last night she had a nightmare. she was fussy going to bed, it took a long while to wind her down she normally falls asleep between 9 and 10 pm last night she went out around 12. her lungs r very sensitive and i want her to get better but a lot of these meds have really bad side affects and who's to say what will be the long term affects and thats what i worry about the most. i just don't know what to do and I'm very worried. i came across this site by accident but I'm glad i did cuz now i know that this is not safe to give my 21 month old daughter.

My son has been on Zyrtec for the past year - he is now 4. He the sweetest disposition one minute and is a monster the next hating us and wishing we were dead. We assumed that it was his age and possibly a behavior disorder until I read the other entries. We took him off immediately and he is back to the kid we lost last year. This needs to be taken seriously. When I researched the side effects on the drug website they do not mention behavior issues as a possible side effect. My son will live with a runny nose and a smile on his face.

My daughter is 5 years old and has been on singulair for 1 week. i have already noticed a dramatic change in her behavior. she has become irritable, mean, nasty, and emotional. she has had me in tears on a daily basis. she has turned into a monster. we will be calling the doctor in the morning!

My 6 yr. old son transformed...a few days after taking the medication he became extremely hyper. He was unable to contain himself and became nonresponsive. He completely changed even having behavior issues in school...which were almost non-existent prior to taking this medicine. I highly recommend parents donot administer this medicine to their children.

Singulair was a BAD BAD BAD choice for my children. I wish I had never agreed to give it a try. I have three children who were put on it for their allergies to take with their zyrtec that did not seem to be able to keep up. The Doctors all assured me singulair is a very safe and effective drug with very little if any side effects.

Well over the years we have had the stomach pains, vomiting, ear infections, loss of appetite, bad dreams, behavior issues, explosive aggression, unable to focus for long, muscle and joint pains, hair loss, unable to sleep at night because they are restless and cannot settle but unable to wake up in the morning, acting angry about nothing all the time. I was laying beside my son one night because he was sick and I could hear his heart beating so fast like it was going 100mph. He could not settle and when he did he was jerked awake by bad dreams. I gave him a singulair just hours before for his allergies and cough.

The Doctors still tell me singulair does not cause these kinds of side effects. Funny it all stopped when we stopped giving the medicine to them. Now they are eating so much now like they were starving all this time and need to catch up. They sleep like rocks and they are just turning out to be nice children to be around again. And the purple bags under their eyes that the Dr's kept telling me were caused by allergies are disappearing. I am thinking it was caused by not being able to rest. The laughter I hear in my home is like music to my ears. We don't have angry outbursts anymore. The older children tell me they feel so much better now that they are not taking that medicine anymore. My smallest told me his tummy does not hurt anymore. It used to hurt every night but not anymore.

I will never allow my children to take it again. This stuff is like poison to us. The Dr can keep it! I just hope giving this to them has not caused any long term health issues for them that we have yet to find out about.

Merck needs to run a new study on this medicine. I wish the FDA would yank it.

My 10 year old daughter was prescribed Zyrtec for cat/dog/other allergies in the spring of 2004. She had severe emotional outbursts, to the point we were considering doing counseling. She was angry, arguementative, extremely tired and suffered from insomnia. We took her off when her allergies subsided. ALL of her behavior issues have been non existent. We didn't realize until this month when she started it again that her behavior changes coincided directly with taking the medication. We have our daughter back!

My 2 year-old daughter is having similar behavior issues to those described here. Her doctor put her on Singulair in the spring, and we noticed a change in her behavior, so I took her off of it. Now, after having more asthma symptoms, a new pediatrician prescribed it to her again. When I told the doctor that it had turned our daughter into a monster when she took it before, the doctor said she didn't believe it was the medicine. Well, after one day of taking it this time, I told my husband that I was having deja vu, that our daughter was behaving exactly the same way. He said, "Well, she IS two"--implying that he didn't believe it was the medicine either. Well, yesterday, when he came home from work while she was in the middle of a horrible fit, he said, "Don't give her Singulair again." She is normally a sweet, well-rested, sociable little girl (yes, she is 2, but even if she throws a tantrum, she can usually be reasoned with or distracted. . . but not on Singulair). On Singulair she's a tantrum-throwing mess.

My son just turned 5 years old. Singulair is the only medicine my son has been taking in these last few months. He had been off of it for about a year, until May 05 he started taking it again. His behavior became terrible. I did not put two and two together, that the medicine was doing this to him. Constantly in trouble in pre k. Bouncing off the walls, bad temper, head aches, a couple of nose bleeds, muscle leg and ankle cramps (which I thought were growing pains), not sleeping through the night, not LISTENING at all, hyper, sarcastic, rude and eating all the time. I have had him off singulair for a few days and he is getting back to the sweet little boy he use to be. I can't believe the change in personality. Thank you for this website and I hope other parents read this and take their children off singulair. I was thinking about taking him to a therapist because I just did not know what to do anymore. So the other night I was thinking what has happened to him to cause such a change. Then I thought I will do some research on Singulair and boom I could not believe he wasn't the problem, singulair was. I was at my wits end until I found this website and noticed similar patterns with other children. I feel awful I have been giving these terrible pills to my son. I cannot believe doctors are prescribing this to little children. How unfair. He has been in so much trouble lately being disciplined. He use to be on it a couple of years ago and was also bad and I asked the ped and he told me no behavior problems could be caused by singulair. So I just filed it in the back of my mind and choked it up to terrible two's. Well I say bull. My poor child went through hell. Help your little ones and do not let them take singulair.
