1	allergy, sinus, astma	BEHAVIORAL, TANTRUMS, OCD, ODD, MASTURBATION ( YES AT 3 YEARS OLD), DEPRESSION, PROBLEMS SLEEPING, ETC ETC AND ETC.	my daughter was sick the whole winter last year, she was about 2 and 1/2 and had started daycare every morning. After catching about over 10 different viruses and always having bronchitis (forgive me my English) then end up taking antibiotics and more and even ending up with pneumonia...she has allergy + sinus + asthma issues... so our pediatrician recommended putting her on singulair, I resisted a bit, do not like drugs at all, but after all they are the doctors, right? It seem to have helped her because she stopped being sick. she took for 3 months and summer came, I stopped... winter is here again and she is sick again, now also her baby brother 8 months old, both sick and her doctor told me to put them both on it, so...I buy the singulair only for her and start giving to her...4 days later I notice my sweet angel going out of control, unbelievable change...tantrums, completely out...plus other things...NOW I GO BACK IN TIME LAST YEAR WITHOUT MAKING ANY CONNECTION I COULDN'T DEAL WITH MY DAUGHTER ANYMORE TOOK HER TO A BEHAVIOR PEDIATRICIAN. HE WANTED TO PUT HER ON ANTIDEPRESSANTS, DIAGNOSED HER WITH ADHD, OCD, ODD AND MORE. AND AGREED BECAUSE SHE WAS OUT OF CONTROL. TANTRUMS, CRYING IN THE MIDDLE OF THE NIGHT, AND I CANT REMEMBER ALL RIGHT NOW...BUT MY CONCLUSION IS THAT SWEET SMART LITTLE GIRL CHANGED AROUND THE TIME SHE TOOK THE SINGULAIR AND AFTERWORDS SHE GOT BETTER BUT I NEVER REALIZED UNTIL NOW THAT I GAVE IT AGAIN AND INSTANTLY SHE CHANGED...I JUST PUT MY DAUGHTER T	F	3.5	3 months 4mg 1X D		2/6/2010
1	exercise induced asthma	diarrhea, constipation, stomach cramps, depression, anxiety, anxiety attacks, suicidal thoughts	Quickly determined that the daily diarrhea and other gastric symptoms were due to taking Singulair, but thought I'd wait it out and see if it went away. However, after reading up more on this medication, I realize that my anxiety and depression were not due to other circumstances in my life that are going on concurrently. I am a strong person mentally and can deal with problems. But I actually had suicidal thoughts twice and that really scared me. So I'm tossing this medication in the garbage tonight. I'll stick to my inhalers, thank you very much. Can't wait to detox this medication out of my system.	F	45	22 days 10mg 1X D		2/5/2010
1	allergic rhinitus	agitation, hyperactivity, deliberately unfriendly behavior, oppositional, defiant, bad dreams, tempertantrums, kicking, aggressive behavior, talking too much	My son is going off tonight...a normally energetic kid has become overly aggressive, running into us, head butting with force, defiant, combative, purposely antagonizing. He is calm at preschool and within seconds of leaving is yelling, jumping, hitting - unusually aggressive and agitated. He will talk incessantly and then just crash and fall asleep. His emotions have been on a roller coaster. This stuff if awful. I feel horrible he lasted this long on the meds.	M	4	10 weeks 4 mg table 1X D		2/3/2010
5		I had little side effects. Headaches and trouble sleeping.	I had truly the worst asthmna a that a person could have. I was in and out of the hospital and at one time, I spent 11 days in intensive care on a respirater. My lungs were failing. I was given my last rites and at 28, I was dying. When I finally got better, my pulminoligist put me on Singlair. It has changed my life. For one thing, I have a life now. I have a child and I am happily married. I believe from all the readings that Singulair is toxic in children. I can only speak for myself and it saved my life.	F	35	7 days		1/28/2010
2	asthma/allergies	outbursts, argumentative, anger, depression, hyperactivity, expressed suicidal ideation.	My 9 year old son began taking when he was 6. His teacher thought he was ADHD. Last year, I began to think it also. We ran out of the medication and i took two weeks to refill it. The second week he had a really good week at school. The next week he was back to being a problem. I remembered reading about side effects but never made the connection until then. I have since stopped giving it to him and the negative behaviors are dissapating. I am angry with myself for taking so lomg to see the connection. He is at his 3rd school in 3 years because of problem behavior that could have been avoided!	M	9	3 years		1/28/2010

1	Asthma/Allergies/Chronic Sinusitis	When I was about 13 my doctor put me on this medication to help with severe asthma and allergies. I was an extremely happy, intelligent and outgoing child before I was put on this medication, but once I began taking it, it was like I was a different person. I was suddenly extremely irritable, prone to aggressive outbursts, chronically depressed, developed severe insomnia, developed a severe anxiety disorder accompanied by massive and frequent (3-6 times per day) panic attacks, began to fall asleep and hallucinate during daily activities, catatonic episodes, experienced horrible nightmares and perhaps most annoying of all, I experienced uncontrollable and unceasing tremors and 'ticks'. After 1 year on Singulair I attempted to commit suicide, 6 months later I attempted again, and again 2 years later. When I was 18 my doctor took me off of Singulair because my asthma had seemed to improve, one year later she put me back on it because of chronic ear infections. That one year that I was off	I have taken myself off of singulair again, after happening to review a patient information handout at work one day (I am a pharmacy technician). I have been off of it for a week now and already I am beginning to see beauty in the world again and feeling more confident in myself. I feel as if being on singulair has ruined my life. My whole adolescence was consumed by this drug, and I was coming close to trying to kill myself again, before I took myself off of it. This drug has taken away time and ruined relationships that I will never get back. I am writing this note on here in hopes that patients and parents consider very carefully the side effects of this medication and the implications that it carries with them. Yes, it got me off of my inhaler, but I paid a heavy price for that convenience.	F	20	6 years		1/25/2010 Email
1	Allergy Induced Asthma	Night terrors, hallucinations, anger, depression, violence, suicidal thoughts/comments, extreme mood swings, crying, moodiness.	I had no idea these were side effects. I don't remember reading any of these when we started the Rx. My friend told me about her son and his experiences, which were exactly like my son's. We are done with Singulair.	M	11	2 years		1/24/2010
4	Chronic sinisitis	None.	I have been taking this drug for 2 weeks and I have not noticed one thing yet. I have had sinus infections forever and constanly stuffy. I hada infection and went on this instead and I honestly can't say anything bad about it yet. I have been reading through all of these comments and I find it hard to believe it has such large side effects for some people. however, Everyone reacts differently!!	F	23	12 days		1/23/2010
1	asthma; wheezing, night cough	Nightmares.	I gave my son one pill. After he went to bed I searched for side effects. I saw all the terrible reviews and hoped for the best. I won't put him on steriods because he is very small for his age and I don't want his growth delayed. He woke up with nightmares all night. He whimpered and shook as he lay beside me sleeping. My heart broke. I'm so glad I knew this was a side effect so I could immediately stop giving it to him. We're looking into alternative treatment (traditional chinese medicine).	F	32	1 days		1/22/2010
1	Chronic nighttime asthma	For the entire 9 months that our 4 year old daughter was on Singulair, her asthma symptoms completely disappeared - BUT - she experienced constant nightmares, almost every night. I put it down to 'a phase' until I realised that it was associated with Singulair. I feel dreadful as a mother for taking so long to realise that my daughter's nightmares, which really distressed her, were caused by the medication. We recently reduced her dose and then increased it again - as soon as we increased it she started wetting her bed every night. I will never ever give her this medication again. I think there should be a thorough investigation into this medication.		F	34	9 months		1/21/2010
1	Asthma	My son has been taking Singulair for a year and a half. Initially, I didn't notice any changes, but over the past several months, he had developed a habit cough and has gradually taken on strange eye tics. Kids have started noticing at school. He also seems to be a little on edge and not the happy go lucky kid I know. I took him for his annual pediatrician appointment to discuss the tics and he suggested I look at the Singular that the allergist had prescribed. I am taking him off it immediately and I feel that this drug is a horrible poison. I feel terrible for not making the connection	sooner, but better late than never, I suppose.

1	asthma allerigies	depression,anxiety,sleep disorder,school phobia,ocd	while my son was on this drug,my family and my child went through hell,this drug is poison for some.It is so important that anyone who has experianced the rath of this drug make a report to the fda,this is the only way someone may listen.The doctors sure do not seem to recognise the havoc this drug causes,if they did they would not brush off us parents,send our children to therapy and give more drugs to combat the side effects of this benign pretty pink pill that is killing children	M	11	3.5 days		1/17/2010
1	asthma	aggression, extreme agitation, irritable, tantrums and depression	This med was prescribed to my son when he was 3 years old however it wasn't until he was 4 that he took 4mg daily then 3 months prior to his 6th birthday is when the dose was increased to 5mg...which is when all hell broke loose. Last week when I found this sight I cried. All this time it was the singulair and not one doctor attributed my sons change in behavior to this horrible drug. Now that we have stopped it some of the aggression, depression, agitation, and tantrums are improving...I hope with time we get our son back completely and that the terrible side effects we have experienced go away. My poor son is only 6 years old and has been thru hell because of this med. I am sure many patients do fine on this medication but it isn't for everyone. I just wish I realized the link sooner.	M	6	2.5 years		1/16/2010
4	Asthma/Allergies	None when on the medicine. If I take a break for even a day or two it affects my mood. I get highly aggressive, cry for no reason, and even have what I would call severe depression.	It works great and helps, but I skipped a few days on purpose this last week to see if it still caused the same reaction. After two days I was scaring myself with my thoughts so I went back on it. I also take a lot of other allergy/asthma meds and this was the only variation in my routine. I have not ever have thoughts or feelings like that before, besides when I have missed doses of Singulair. I tried talking to one of my doctors about it but they just advised me not to miss a dose. Be careful when starting because if you have the same side effects you may not ever get to stop.	M	23	3 years		1/14/2010 Email
3	allergies	slight drowsiness, dry mouth, dried out sinuses similar to what a cold or flu medication will produce	Was as effective as Zyrtec and Chlor-Trimeton, but not as effective as Claritin in clearing out my sinuses. Singulair doesn't work well enough for me to deal with the minor side effects, especially when there are other drugs (Zyrtec and Chlor-Trimeton)that have no side effects for me.

1	allergies	nigthmares, fatigue and massive depression	i was prescribed this medicine to take for allergies. i am actually asthmatic and have never heard of this medicine and have been shocked by the massive side effects, i have felt in only 4 doses. each night, i ahve had nightmares, that i couldnt get out of, and that caused lack of sleep and then during the day have felt the worst sort of depression one could feel - like the world was ending and i could cry over anything. i was aggitaed and snappy ...... and i am a pretty happy, balanced person. PLEASE ask your doctor for more information before you take it and BE CAREFUL, there is something in this drug that is lethal	F	36	4 days		1/3/2010 Email
1	Allergies	Anger, yelling, frusration, disrespectful communication with family, exhaustion, lack of patience, trantrums, problems listening	I originally asked my 7 year old's primary care physician for recommendations for sleep issues with my son. My son has always been a perfectionist and easy to anger, but he has a sensitive heart and always wants to please. I thought his initial problems were due to sleep problems we had seen with his inability to sleep through the night. He had chronic nasal conjestion. He was put on Singular. I was so happy with the results. He no longer had the 24/7 goopy nose. BUT 1 year later, I have an 8 year old that can not control his temper, we feel like we can no longer talk to him withour him going into a trantrum. We have gotten to the point that we feel like we are yelling at him all the time and he responds unreasonably to us or anyone. It was not until my neighbor took her son off singulair and said she notice he calmed done, that I began to tie the Singular to my somes worsening problem. I had just scheduled a meeting with his physician to talk about possible behavioral problems when I googled 'Singulair" side effects and found this page. I am so releived. I hope this will give us back our son and help him to gain control of his emotions. I know he is a smart, caring son in side this poor child. I am taking him off this drug immediately!

1	Asthma & Allergy	Mood swings, tantrums, break downs, crying, out of ordinary behavior	My 2 year old son has been on these meds for 1 week! At first we thought terrible 2's but as the behavior got worse I started looking online and found this site. My son now has a new doctors appointment and will NOT be taking this drug again! I have never seen him react to any medication like this.	M	2	7 days		12/30/2009 Email
1	allergies	teeth grinding, aggression, not listening, mood swings, tantrums, complete melt downs and unable to calm down for up to 20 mins. hitting, biting	My 2 year old son has been on this medication for 90 days and experienced all of the side effects listed. At 1st we thought maybe its just the terrible 2's everyone keeps talking about, so we did more research on behavior/discipline, but quickly realized this was way beyond a phase and was only getting worse. We finally made the connection to the medication and took him off it. Too little too late though, he was ultimately kicked out of daycare because of his aggression. He has been off of the meds for 3 weeks now and we are going through the "detox" phase. Things are better, but I am wondering how long this will be in his system and how long these horrible side effects will last. I just want my sweet little boy back!!	M	2	90 days		12/29/2009
5	asthma	My 8 year old son has been on this medication for 3 years and there have been NO side affects. His behavior is the same he does not have nightmares. All I have noticed is he does not cough excessivley and that is a major plus in my book. I was checking this website cause he has gained weight but he has always been chubby even as a baby. Probably nothing to do with the medication.	I would recommend this medication to anyone.	M	8	3 years		12/28/2009
1	Asthma- cat allergy	Night terrors, screaming up to 40 times a day, hitting, aggression, hyperactivity, insomnia, lack of attention span, where previously there was a great one.	I only figured this out a few days ago. She is also on Advair inhaler daily. I've even changed her diet. I'm so glad to see that these medicines may be the cause of behavior that is soooo terrible, that we've had to isolate from family members.	F	4	8 months		12/21/2009
3	asthma	depression, extreme anxiety, suicidal thoughts, rage, rash, leg pain, tingling/burning under skin	I just recently went off of this drug. I thought that maybe it could be causing my extreme anxiety. After reading this, it appears that I was right. I have been off of it for only 2 weeks. I feel calmer than I have in a long time. Even husband commented that I sound different. Not sure what to do about meds. Dr wants me to try symbicort. Very hesitant to try something else. Have had issues with other inhaled steriods. Must be better alternative.	F	48	2 years		12/20/2009
1	asthma	aggressiveness,tantrums,nightmares,hearing voices,ADHD behavior	My six year old son has been on Singulair for almost one year. It has worked for his asthma but we have seen a sweet happy little boy turn into a monster! The changes did not happen right away but slowly. After his dosage was increased when he turned six things have escalated. He has been a crazy child since starting kindergarten. He is now in the care of a child psychologist, child psychiatrist and a team at his school. He has been suspended for his behavior and kicked out of his after school program. He started meds for ADHD 3 weeks ago with little improvement in his behavior. Like many other parents I have asked the doctors can it be the Singulair and they all say oh no way! After talking with a pharmacist who told me of the horrible side effects - which by the way are not listed on the drug companies web site - I have chosen to stop the Singulair. I pray that it is the cause and that I will get by sweet loving little boy back. Something should be done about this and everyone should complain LOUDLY to the drug company! If it turns out that our world has been turned upside down by this and hundreds of dollars spent on our son's mental health issues someone sure will hear from me!!!!!!!!!

2	astma	my 4 yr old daughter has allways been strong minded. she just started nursery in sept. her we chest had been giving her bother and i was worried about her attendance in school so her doctor prescribed singular chewable. when i thin back to when she started talking them she cried non stop at night for 4 nights she has now become anxious crying and really bad tantrums i have decide from today that im going to take her of these tablets because she is crying non stop from she gets up till she goes to bed.	woulnt recommend these tablets this is a mother whose child had to get 12 teeth out with medication for asthma	F	4	3 days		12/16/2009
2	asthma	mood swings, crying, obsessive compulsive behaviors, anger.	It worked great for her asthma, but the side effects are awful. We will be stopping this med to see if the other behaviors improve.	F	7	2 months		12/15/2009
1	Allergies	Seperation anxiety, uncontrolled crying, general anxiety	My 7 year old has been taking drug on and off since she has been 2. She has suffered on and off from bouts of crying, unexplained fears and SEVERE seperation anxiety that started out of nowhere. We were never able to pinpoint a reason until reading experiences of others. I mentioned this to her doctor when it all began and the idea of this med causing anxiety was dismissed. I feel so guilty for not checking into this sooner, and especially for not persuing it further. She asks way too many questions about death, dying and cemetaries and we could never figure out why. She cries when happy, sad, scared for just about anything at all. Always intermittently, never consistently. When you ask her why, all she can say is I can't help it. We could never figure what the trigger would be, now I have finally have a place to start. She is off the med for 10 days now, and hopefully it will work it's way out of her system sooner rather than later.	F	7	4.5 years		12/10/2009 Email

1	asthma	frustrated, unable to concentrate, teacher and family noticed a definite change in personality and performance, frustration lead to verbally expressing wanting to "kill myself"	This is about my very intelligent, sensitive 8 yr old nephew. This scared our whole family. THE BEST WAY TO BRING ATTENTION TO THESE ADVERSE EVENTS IS TO REPORT THEM TO THE DRUG MAKER MERCK AT 800-444-2080 AND THE FDA AT http://www.fda.gov/medwatch. THIS WILL HELP BRING ABOUT AWARENESS AND CHANGE.	M	8	3 weeks		12/7/2009 Email
1	coughing related to asthma	severe nightmares,aching legs	Please do not give this to your children! My confident child turned into a clingy, insecure little girl within 3 days. She had "bad nightmares, mommy" and said they were really bad and she didn't want to talk about it. My little girl normally describes everything in detail. She also had aches in her legs.	F	4	3 days		12/7/2009
1	seasonal asthmatic symptoms	nightmares, anxiety attacks, anger, change in behavior	My 3yo son started taking this 4 days ago. The first night, he had a nightmare. Starting soon after, he started hearing "sounds". We never figured out what he heard, but he'd climb the walls screaming even when he would hear you scratch. This evening he had a 2 hour anxiety attack. His personality has changed even in this short time: he's moody and angry. I wondered if it was the medication, and Google brought me here. There is now no doubt in my mind, and my child will no longer take this.	M	3	4 days		12/6/2009
1	Asthma; persistent, intense cough	Significant increase in shortness of breath and fatigue. Prior to Singulair, I was able to walk on treadmill and do some light activity, but after only 2 days of taking 10 mg/day, I felt ill and unable to engage in normal conversation, so I stopped medication. It took a few months just to get back to baseline.	Allergist's recommendation was to continue taking Singulair and to begin using a combination inhaler. I decided against that advice as I am afraid of inhalers; also I believed that following his advice would take me down the wrong path (more meds, and thereby more side effects & interactions). I've been waiting for appt w/new allergist who uses sublingual allergy meds--supposedly less problematic. My chronic cough has caused organs to prolapse, so I hope the sublingual med helps before I need operations to correct prolapses.	F	58	2 days		12/4/2009
1	seasonal allergies	anger, screaming, hitting, crying, excessively tired, quickly escalating emotions	My 6 y.o. daughter has only been on this medication for two weeks but it has been the worst two weeks of my life! Her personality changed almost overnight from an occasionally moody but usually sweet child to a hostile, angry, almost violent little girl. She would go from zero to full-on fit in an instant. I talked to everyone including her teacher and school social worker, desperate for an answer until I thought about the medication connection. We stopped it two days ago and already she has calmed down tremendously. Trust yourself as a parent! A child's personality should not change so dramatically overnight.	F	6	16 days		12/4/2009
1	Allerty, Asthma, Congestion	Extremely emotional, uncontrollable crying, kicking, screaming, unable to calm down, back aches.	My 3yr old son was on singulair for 2 days. It cleared up his symptoms immedietley, but that is when eveything else started happening. He went to preschool and had a melt down over nothing, kicking & screaming, rolling on the floor. He could not calm down and everything seemed to agitate him more. The tantrum lasted for 90 min. and I had to come get him & bring him home. The next morning he started complaining that his back hurt, the crying started again and his teacher said he has been in a bad mood all day. This was not my son. I was so worried. The Dr. said to discontinue taking it. Now I'm wondering how long it stays in his system.	M	3	2 days		12/3/2009
2	allergies	hyper-active followed by extreme fatigue, pounding heartbeat, confusion, anxiety, crying spells, depression, loss of focus,	my daughter started taking this medicine about 5 months ago to control allergies. Other medicines did nothing for her allergies but Singular controlled her symptoms quickly. Slowly her personality changed. At first she was very chatty and no longer shy. We attributed this to benefits of after school activities. Then she slept all of the time. Everyone tried to tell me she was just growing. She began eating only half of what she did before. Then, she would suddenly start crying and running around saying "I don't know what I am supposed to do. I can't think. My little heart is beating so fast it's pounding." Her focus on schoolwork declined and her behavior grades declined. I could not imagine my 6 yr old suffering with a mental breakdown. Then, for the first time, the warning label appeared on the prescription. I thought it was a mistake until I found this site. Now it is all clear. I discussed it with her doctor and stopped Singular immediately. It is now listed under her drug allergies. I would never give this to a child. According to her doctor this medicine actually is in the same family as antidepressants. There are multiple warnings about antidepressants in children. I can't believe they are marketing this medicine to children. It needs to be banned for use in children. I pray all effects are reversible.	F	6	5 months		12/2/2009
1	Presumed allergies, cough, wheezing	Mood swings, odd behavior, nightmares.	I only gave my son 3 doses of this medication. Two of those 3 days, he had nightmares. He was also a little more moody than usual and had behavior that was totally out of character for him.	M	3	3 days		12/2/2009
2	to control asthma-inducing allergie	Extreme anxiety, worrying, and obsessive compulsive behavior	I am sitting here in tears because I have only stumbled upon this information and and will stop giving this to my daughter immediately. My daughter has always been somewhat shy and concerned about things, but within recent months, she has been having extreme anxiety, running back in to check the door locks, asking "what if...?" constantly. A babysitter's house was broken into and our friend's car was stolen recently, so I was attributing her worries to those incidents, but it's just gotten worse and worse. She has even cried a couple of times at school, which she's never done. Now as I read all these testimonies, I have to think it is her Singulair, and feel awful that she's been so affected by this medicine and that I had no idea it was the cause. She recently started Flovent, and her stomach has been hurting, so we'll probably try stopping that too and see if that helps. Thank you all for posting.	F	8			11/29/2009 Email
5	Asthma, COPD, Allergies	Stomach cramps, but only in the beginning of re-starting this medication.	Due to losing my insurance and financial challenges, I'd been off Singular for about a month, after taking faithfully for about three years with no promblems at all. I will never go off this medication again. I couldn't breath without it. My throat was so scratchy; I was short-winded, hacking cough, wheezing, using my inhaler way, way too much. I was miserable. Within 24 hrs of restarting Singulair, I could breath again. I'm having a little adjustment phase now (some cramping, and sleep disturbance), but because I had taken it for so long with no complications, I expect those to diminish in the next few days. This medication is not for everyone -- especially after reading some of the other posts regarding giving this to children. If it works for you, then it's fine, if not stop taking it(.) It's not as though the side effects aren't reported. Your pharmacy gives you the information when you make your purchase. That's the law. I love the stuff.	F	47	3 years		11/27/2009 Email
2	allergies; dermagraphism; asthma	irritable; terrible moodswings; nightmares; zoned out; hyper & then crashes	the doctors kind of make you feel like you're imagining these drug reactions. they told me that singular was an amazing drug and did all kinds of amazing things for the kids when i took my daughter off it the first time. urged me to put her back on it if i wanted her better.

1	cough induced asthma	nightmares, headaches, acute anxiety, body aches, vision abnormalities, lack of focus, extreme fatigue, mood swings, etc... etc...	Our daughter was prescribed this poison by the ped. physician when she was 4 yrs old for cough induced asthma. For the 2 1/2 years she was taking singulair we had every test imaginable done on her to diagnose the complete deterioration of her mental and physical health. The physician never once recommended discontinuing this drug. We decided ourselves to take her off it and within 2 weeks things began to turnaround. It took a good year and a half for 95% of the symptoms to disappear. She is 11 now and there are still some lingering effects of this poison, probably due to the length of time she was on the drug.

1	ADULT ASTHMA	Beware- I am basically a level headed person- I gradually drifted into a deep depression and crying spells after 2 weeks. Takes several days to realize it is this drug that is this causing this. Takes another several days to detox it from your system.	This is the second time I have taken Singulair and experienced the same thing. It helps so much with my lungs that I had forgotten that I had the same side effects 2 yrs. ago. The experience is so scary I feel this drug should be taken off the market. If not for this web site I would probably think I was losing my mind.	F	58	19 days		11/19/2009
1	allergies	anger issues, self pitty/ depression	My 5yr old son was taking this for one month. One week into taking singulair he started saying Mom you hate me dont you and also having problems in school like getting up right in the middle of the teacher teaching class and walking around. He has recently started hitting other kids in his class. This is all VERY unlike him. He has always been the sweet kid and very lovey and always everyones friend and taking up for the less fortunate.

1	asthma	Singulair has made my family LOSE YEARS OF OUR LIVES! My 10 yr old took this med since she was 6. I would occassionally take her off of the med when her asthma was controlled. She had been off for a couple of months and she started having an asthma attack so I put her back on singulair along with her other drugs she had already been on. It was during exam preparation and she was in LA LA Land! spaced out and unable to concentrate for weeks! I knew that she had trouble focusing, remembering, concentrating for years. I finally made arrangments to have her tested for ADD.Ironically I took her off the med and it was like someone turned the light back on!! Since then we have not gone back and I have a different kid!! no more bullying, no more aches and pains, no more concentration issues just a lovable, sweet, kind, child that I once knew years ago. All I can do now is pray and hope that this drug did not do any permanant damage to her precious organs!!! The government has taken those years	DO NOT GIVE THIS DRUG TO YOUR CHILD OR ANYONE!!!!!!!! THE GOVERNMENT SHOULD BE ASHAMED OF THEMSELVES FOR APPROVING THIS!!!!	F	10	4 years		11/16/2009
1	Chronic Cough	Hair Loss, Rapid Weight Gain, High Cholesterol, Muscle Tension, Rashes.	I came to this site to find out if my son's recent health issues were due to the RX he's taking. It appears they are indeed the culprit. Our 20 yr old son developed a chronic cough in April 2007. Many meds were tried to relieve the cough. Todate, no meds have given him relief. For the past 18 months he has been on Singulair. For the past 12 months he's also been on Astelin and Nasacort. In the past year his total cholesterol reached 257 (up from the previous 180's), he's gained over 30 lbs (despite dieting), has had significant hair loss, neck/jaw tension, headaches and some hives. The mfg drug side effects sheet didn't list any of these items; however, after reading previous comments I feel the meds he's currently on (particularly Singulair and Astelin may be the culprits. We plan on having our son stop these meds immediately and revisit his allergist for a consult. We are now considering acupunture and a holistic medicine to his chronic cough. The medical profession has failed him terribly.	F	60	18 months		11/14/2009 Email
1	Asthma/allergies	Bedwetting, hand numbness	Was prescribed for my 4 1/2 year old daughter for seasonal allergies when her Xyzal and Nasonex weren't doing enough for her and she started to have worsening nasal congestion, continuous post-nasal cough. She has NEVER had problems with bedwetting since she was completely pottied trained at 28 months. 2 times this week since starting Singulair she has wet the bed at night even though she was still alert enough to wake up last night one time to void. She also keeps intermittently saying "my hands feel tired" which she has never complained of in the past. I think this is probably the way a 4 year old complains of hand numbness. I haven't noticed any significant change to her breathing problems compared to last year prior to starting Singulair. She is getting better but no faster than last year when we only used the Xyzal, Nasonex, Orapred, Xopenex. Am taking her off Singulair today and will not use it again. Also, what about all of the crazy warnings: avoid people with colds and flu while taking this medication??? Is that possible right now???	F	4	5 days		11/13/2009 Email
1	Allergy problems, sinus	I am a glass half full type of person. Within 36 hours of taking this medication I was having very depressing thoughts, by the end of the second day I felt like I was having an out of body, numbness everywhere... terrible side effects. Found this link, read other comments. Stopped about 72 hours ago and returning to normal quickly.	It did clear nasal passages but need another solution, the side effects are just too great.

1	coughing asthma	Prescribed by pediatrician for our 7 year old daughter. Daily intense headaches which were dismissed as not related to the medication by our doctor - although they started a month or so after going on the medication.. Went as far as getting a CT scan because of the duration, frequency and intensity of the headaches. Additional side effects of occasional fever, dizziness and irritability. We are stopping the use of this drug immediately. The published side effects are alarming - should've done more research before taking the doctors advice on this one. No doubt we will be more careful in the future.		F	7	3 months		11/10/2009
1	allergies	rage, anger, no concentration, yelling, trouble at school	My 8 yo has only been on this med for less than a week but he is getting in trouble at school for not doing any work at all. He got caught putting scissors in his mouth and threatening to cut his tongue out! This is when I snapped and thought it had to something new going on. This wasn't my child.	F	35	6 days		11/10/2009
2	asthma related cough	bed wetting	My 9yo son has had significant issues with bed wetting in the past but we finally had it under control. He just started singulair 5 days ago and has wet every single night - sometimes twice! This just can't be worth it. He already has frustration and behavioral issues so there's no way I want to risk adding to his problems. He's off.	F	39	5 days		11/9/2009
1	asthma/allergies	Horrible Mood Swings	Although Singular did help with my 8 year old's symptoms the side effects were horrible. She already was having some issues at school with attitude problems, this drug made them much worst. She was sent home almost every day with notes from school for taking back, being disrespectful towards others, stealing, lying, cheating. We had never had this many issues in a span of a week. We stopped giving her the medication and the behaviors have also stopped.	F	8	14 days		11/8/2009

1	allergies	rage, suicidal/homicidal thoughts, mood swings, loss of concentration, hyperactivity	My 6-year old son was prescribed singulair for allergies. On the third day of taking this drug, he became an emotional wreck. He was so hyper, seemed out of control of his body - literally bouncing off the walls. Grandparents and friends even noticed the change. He became extremely frustrated because he could not concentrate on any task, game, etc. Very unlike him. THEN he started talking about wanting to kill people, and himself. I was beyond shocked and scared. At first, I didn't even think of contributing it to Singulair, until I started researching side effects. I was outraged. I took him off of it immediately and he was back to himself within 24-48 hours. A week after this experience, I received some health alert email about the psychotic reaction dangers of singulair to children. It is terrible to think of a "simple" allergy med causing such a scary and life-threatening reaction. I warn everyone I know with kids, just in case, and one of my friends' sons is experiencing similar problems.	F	35	3 days		11/5/2009
2	Allergies	Insomina, aggression, moodswings, screaming & temper tantrums.	My Ped prescribed Singulair for my 2 yr old daughter, although it works wonderfully for her symptoms,after 2 months the side effects have just become too much.	F	2	2 months		11/2/2009 Email

2	asthma/allergies	agressiveness, tantrums, crying, yelling out, anger, mood swings, not listening, unable to focus, 360 change in personality.	My 4 year old son took singulair on 2 occasions for about a month each time. It did seemed to help his allergies, but at the same time his personality changed drastically. At first I thought he was going through a phase. He became a different child. very difficult to deal with. I feel so guilty about getting angry at him for his behavior while on this drug. I finally made the correlation and took him off of it. After the drug got out of his system, he was back to his usual sweet self (both times). I hate the fact that I was punishing my child for his behavior when it was my fault for giving him this poison. Be careful giving this to your child and watch out for the side effects. It may work for some, but it seems like it has a bad effect on others. It is sad with the kids because they can't communicate how they feel like and adult can. What good is a medication if it makes you unable to function.	M	4	2 months		10/25/2009
1	allergies	insomnia, fits of crying, seperation anxiety, irritability	I take this medication myself and it has been a miricle drug for my lifelong asthma and allergies. However I noticed side effects in myself of depression and fatigue. I have tried to give it to my son two different times as prescribed by the ENT doc. Each of the intervals I've tried it he gets the listed side effects. I just got very angry because my son will not stay asleep. It is absolutley awful and has really alerted me that my seasonal depression could be intensified by this drug. If it affects him so dramatically then it could be the reason I have been so depressed for years. I went on the computer for support. I will not be giving him singulair EVER again. I'm going to go hold my little boy now. I feel so bad that I tried to give him this drug again. Doctors are really blind as to the side effects of this drug. It is not such a miracle drug to me now.

3	Asthma and allergies		My almost 4 year old has had issues with ear infections and breathing since birth. He began taking Singulair about 4 or 5 months ago when our ENT suggested that he had his adnoids removed and I decided to take him back to the pediatrician to discuss it first. After reading all of the comments posted, I am beginning to wonder if all of my son's behavior that my husband and I have noted in the past few months is attributed to it or to something else. I am going to stop giving him Singulair for 2 weeks to see if his behavior changes. I hope that is long enough to get it out of his system. If anyone has any feedback, please share.

1	seasonal allergies	My second grade son began crying at school and started having seperation anxiety. He began crying at the bus stop in the morning and not wanting to leave us. This was very unlike him, so this site we found made us wonder. His doctor agreed to have him stop Singulair to see if that was the culprit. We are very happy to say within three days off of the Singulair, he is having no more issues with the separation anxiety and no longer crying at school.	His allergy syptoms went away, however the singulair was in conjuction with an antibiotic so unsure which cleared the heavy cough.	M	8	3 weeks		10/22/2009

1	Asthma	Dramatic mood changes / extreme aggression	My 8 year old son has been diagnossed with depression and is on a mood stabilizer and anti-depressant. After several painful months of trying to figure out what was going on and how to help him cope. We FINALLY got him to a place where he could control his behavior, emotions, and just be a happy kid. Then he was diagnossed with Asthma and was put on singulair... Now we are seeing extreme rage and anger in him once again. The only changes was by adding this medicine. The psychiatrist and pharmacist both said adding this medicine to the two he is already taking should not have any effects on him. If they only lived in my house?? I don't think they would feel the same way.	F	36	3 weeks		10/14/2009
1	allergy induced asthma/sinusitis	intense, unexplained depression; rages.	My daughter was put on this from 4-5.5 yrs with significant behavior changes resulting in many sessions on willful children and behavior modification. We did not like our own child and were concerned about a total lack of empathy for others. We attributed her dramatic improvement to a sweet, even tempered child to entering kindergarten. In hindsight, the improvement actually began when we discontinued singulair during the summer. We put her back on singulair when she was 8 and noticed a return to the same out of control, raging behavior. She sat in her room and sobbed uncontrollably, scaring us and herself because she had no reason for feeling so incredibly sad. After 2 weeks we discontinued and noticed an immediate return to normal within 48 hours. I am so angry that every doctor we saw denied that this drug caused any side effects!! The drug was said to be "benign" and absolutely "free of emotional lability issues." This should be given with specific pre-warnings and advice for careful observation. It is a useful drug for severe, uncontrolled asthmatics, but has no place in a physicians list of approved meds for average sinusitis, allergies, or managed asthma in children of any age. Drug of last resort. The FDA and Merck are seriously hiding facts that parents on this board are seeing and reporting. Direct cause and effect.

1	allergies	This was given to my almost four year old daughter, she became very aggresive, crying over evrything, very moody, angry, clingy, loss of appitite, just completely changed her.	I looked up this med years ago when the doc wanted to give this to my daughter, I saw whet it did to other children so I told the doc no, years later she still has her allergies she has been plaged with them since about 10month old and has had five sets of tubes for her ears and her atinoids out twice. Her father took her to the ENT do to the coughing coming back and she said her ears itched again which normaly happen when a tube falls out and the ear fills with fluid again, but the doc said it looked fine but said she seemed to have allergies still causeing the cough he said to put her in Singular, after a couple of days I noticed her mood change, at first we thought it was do to number one the age and number two the divorce, but when she started crying over everything we thought she might be getting sick. I was at my neighbors and I said I bet this is the one med I did not want her on, as soon as I pulled up the site I know this is the med that makes kids wig out we threw the perscription right away, now I need to call the doc to see how long it takes to get out of her system. Please do not put your kids though this they do not understand and I feel bad for them having to go though the moodswings of this med.	F	4	11 days		9/21/2009
4	Allergies Asthma	Wow. This has been an eye opener. I came to this site for another medication, but I think I've finally put this together. My 3 1/2 year old has been very aggressive. In fact, got in trouble today at sunday school for starting a fight with a child. He has also been hyper, unusually loud, and has screaming fits. However, a few weeks ago we traveled home to Chicago. We were out of our routine, and I kept forgetting to give him his daily dose of singulair. I noticed that my child was so well mannered, calm, and tried to assist his younger cousin whenever she would have an emotional meltdown. I thought, wow, he's growing up and maturing. Not so. When I returned home, we returned to our usual one dose in the morning of singulair, and he was back to his very difficult self -- constnatly wanting my attention, getting upset at the drop of a hat, difficult sleeping. I think I may have found the culprit. I'm going to keep him off for a week and see if there's a noticeable difference.	The med works for keeping his allergies and asthma at bay, but the emotional side effects are far too demanding on a child -- if not the entire household.	M	3.5	4 months		9/20/2009
1	asthma symptoms for 4.5 year old	emotional, irritable, tantrums, crying over everything, angry, extreme hyperactivity	our pediatrician prescribed this for our daughter's mild asthma symptoms to be taken as needed. she was on it for 4 days and they were unbearable. it took me a while to put it together...i kept wondering what was going on. i did more screaming in those 4 days than i have done in her lifetime. she was completely out of control and angry about everything, throwing tantrums, and was completely disobedient. on the 4th day i called the dr. and asked if her behavior could be at all related to the medication and was told "absolutely not." i was not satisfied, so i searched and found 14 pages of people describing the same thing. i feel vindicated, but also very sad that i gave her this medication in the first place. it needs to be taken off the market for children.

4	Allergies/ asthma	My 7 year old son was able to breathe and not have to use his inhaler as much which was wonderful, but his behavior suffered. He had mood swings, very irritable and aggressive.	After going to this website and on-line I am going to discontinue singular and try another drug to help him. It there were no side effects with behavior he would still be taking it because it is the best medicine that we have found so far to help with his allergies and asthma.	M	7	45 days		9/18/2009
1	Seasonal Allergies	Severe Depression and Agression	My son was on this medication for six months before I finally made the connection between the drug and his behavior change. He became very depressed, nearly suicidal, often telling us that he wished he had never been born, wanted us to kill him, and that he didn't want to live anymore. He was also very aggressive toward his younger siblings. All of these behaviors were way out of character for him--typically a very compassionate and joyful individual. Within two weeks of being off the drug we had our normal, happy, loving boy back. NEVER EVER, EVER give this drug to a child. When I related our experience to the allergist he was not surprised, has seen it before (argh!) and said that my son can't take Singulair, Zyrtec (He had similar results with Zyrtec), or Claritin. Be very cautious of drugs, parents!	M	7	6 months		9/18/2009
1	Asthma	Complete personality change in a little over two week period.	DO NOT GIVE THIS DRUG TO CHILDREN. This drug came highly recommended by our allergist. He insisted we take the drug to help with modest asthma.

I thought that it was a godsend as her breathing much improved and she was able to participate in simple activities like running after being on it for a month or so. At about age 4 she started having headaches, sore throats, neck pain, leg pain, stomach aches and nightmares.	I have had her in the doctors office several times over the last year for these symptoms and never got any answers or indications that the singulair might be causing these symptoms. I am furious! My sweet four year old has headaches all of the time and not one of the doctors mentioned that this could be a side effect!	F	4			9/13/2009

1	Athsma/allergies	I was in the 4thand 5th grade when I took Singular, and at first it seemed to work great and really helped my health. Later on, though, I started having suicidal thoughts and depression, and I was really worried about myself. I would cry a lot and refuse to go to school, and I had a lot of trouble focusing. The side effect of depression and suicidal thoughts with Singular was not yet announced, and my parents couldn't figure out why I was acting this way. Dismissing it as the recent death of a family dog, I went off Singular about 4 months later because I was switching to a day and night ashtma preventative called Advair. The changes in my behavior were apparant, however, we just thought I was finally accepting the death of a pet and moving on. A couple of years later it came on the news about how Singular caused suicidal thoughts and there were already 4 people who were on Singular that had commit suicide because of it.	It works, but it's NOT worth the side affects. Now that we all know it can cause behavior problems, depression, suicidal thoughts, and aggression, there are plenty of other medications that will work without the disturbing side affects.

5	allergies	none	I have mold, tree, and grass allergies (and various food allergies not treated by Singulair). My outdoor allergies cause burning and runny nose, sneezing, sore throat, sinus infections, headaches, inability to concentrate, and light-headedness. Before taking Singulair I already had anxiety, sleep problems, and leg cramps; these things have not changed. My allergies are mostly controlled by Singulair, having mild symptoms with incidental exposure (strong mold or grass smell) or at times such as when cedar or grass pollen is very high (requiring me to also take Nasonex). I have not experienced depression or nightmares. I do not know whether I can stop taking Singulair and not have allergy symptoms; I tried cutting back to 1/2 pill this fall to wean off of it after grass season, but had to go back to the regular dose.

She also lost a lot of interest in food. I had read about the psychological side effects in a magazine, but against my better judgment, her father put her on it anyway.

She is 31/2 yrs old and never has displayed behavior like this before. It was very frightening to see her this way. I literally had to chase her around the house because she kept runnning from "these large spider". I have not given her singulair since.

3	Asthma and allergies	My doctor started me on Singular because I would wake up every night about 3 am gasping for air. He prescribed this more for my asthma then my allergies. Within days, I was sleeping through the night and my allergy symptoms disappeared. It was like I never had asthma.	A few months later, I started having panic attacks in ramdom places where I was not under stress. My dreams and nightmares became more vivid and pretty distressing. I started seeing things move out of the corner of my eye when there was nothing there. My sex drive disappeared entirely. Then, I started hearing voices in my head tell me to kill myself. (At this point in my life, I had a good job, was going back to school partime, and had the most wonderful boyfriend. There was no reason for me to be unhappy) I had enough sense to realize that this behavior was unlike me and then found this site and saw that I was not crazy. I went off the pill and all of the side effects went away in 2 weeks. I took it once after having an asthma attack and had a panic attack within an hour. That was all the validation I needed. I've been off of it half a year and am back to normal except for my sex drive. I hope it comes back. Did anyone else have problems with their libido? The doctor cannot find anything wrong with me but I suspect Singulair. This is ruining my relationship. Help!	F	28	1 years		7/23/2009 Email

2	for asthma	my son who is 6 was put on this medication. He has a mild case of asthma which usually result in hard time breathing a few times a month. We used this medication for about a month and a half and the case of his asthma increased dramatically. We took him off of it and he was having breathing problem almost daily if not every other day for a month or so. We did not want to put him back on this medicine any longer and we treated his breathing problem with nebulizer which usually took only one treatment per case. Eventually his daily breathing stopped and now he's back to where he was before. It has been close to a month that he has not had a case of breathing problem so far.				1.5 months		7/17/2009
1	mild asthma, allergy symptoms	ok where do I start, My son started taking Singular 4 mg after second birthday. I never really thought that his behavior could be caused by singular(the wonder drug). I think back now and I have chills on my arms after reading the stories. They sound so much like my son. It has always been hard for him to make friends and he was hyper and distracted, ADD symptoms, was amazed over death and grave yards, would cry at the drop of a hat and would never followed directions. I just thought it was part of him and we all accepted it. At 6 the Dr. put him on 6 mg singular chewables. I would have never known about this if it hadn't been for me taking him to the dr for his constant itching and rashes and the Dr. suggested we see an allergist. We went to the allergist and they did all the stick tests and found his allergies and then told me to keep him on the singular 6 mg. and he prescribed zyrtec and flonase. After taking 2 days along with the singular 6 mg he was already taking he begain to ta	Please don't give your child this medication, the side effects are really scary and children are suppose to be children not little zombies. I have since gotten and really nice humidifier and I will use that instead of drugs.	M	6	4 years		7/15/2009
