1	asthma	My 12 year old son was recently diagnosed with Asthma and was prescribed singulair. He rapidly changed in behavior, going from a happy, social kid to a depressed, sad, angry, anxious kid. He has mood swings, crying for no reason, sadness, says he doesn't care about having friends anymore, he doesn't want to live this way. Naturally, we were terrified. We could not understand what was happening to our son. Took him to the doc today and she took him off the singulair. I am praying that this will be the turning point for him.

1	asthma & allergies	sleepwalking, night terror, mood changes, no self esteem, anxiety	My 6 yr old son has been taking singulair for 2 years and I am just putting together all of the problems he was experiencing with the meds. He starting showing changes in his mood, nightmares, sleep walking, saying he hates himself, anxiety that something were going to happen to his family etc. It has gotten increasingly worse within the last 2 months so I started looking into what could be causing it. After coming across this website I called his allergist and was told to stop the medication IMMEDIETELY! My son has been off the meds for 3 days now and we are starting to notice slight changes in his sleep and behavior. Lord willing my sweet little boy will be back to normal soon with no lasting effects from this drug. It makes me sick to know I was giving this drug to my child for 2 years.

3	asthma	At first, Singular worked great, turned off my Fall asthma like a switch. The past 2 years, it seems like it is not working as well as it used to. I developed eye twitches that lasted for many weeks, conjuntival cysts on my eye after starting the medicine (Last fall and the fall before that). I cannot sleep well when on Singulair. This year, the sleep problems are huge, i don't remember them being this bad before. After 3 days on this, I decided to quit Singulair. I can't handle the lack of sleep and a 3rd year of eye twitching.	I thought the symptoms were unique to me and not reported by others using Singulair but I am seeing others with same symptoms. I am a little dismayed that when I told the Dr the side affects and she could see my eye twitching herself, didn't say anything. She even sent me to an eye specialist to see about the headaches, conjunctival cysts, and eye twitching. I was dismissed by the specialist as wasting his time. It was nothing important that I had. While Singulair worked great the first few years I took it (I only take it Sept-Dec), the side effects have become too much for me and after 4 days of being on it this year, I am quitting.

2	Seasonal Allergies	I gradually changed. I used to get out of bed like a pop tart and am always on time for work. I eventually didn't want to wake up in the morning, didn't care if I lost my job and would cry all the time for no reason. I finally got to a point where I was driving in my car thinking about running my car off the road into a wall doing 80 on the highway. I just wanted the sadness gone. I am stopping this medication today!	It did clear up the constant runny nose and itchy eyes. The sinus pressure was mostly gone, but I basically thought about sleeping or killing myself all the time about 4 weeks in.	F	29	6 weeks 10 mg 1X D		8/25/2010
3	allergy induced asthma	Excessive weight gain/sleeplessness	My son is 9 years old and has been taking Singulair with wonderful results for his asthmatic reactions, however, he continues to gain weight. He is now in JFL with hard workouts nightly and decreased food intake, and he is still gaining weight. He also has a "moon face" which is charasteric of steroids - which Singulair is supposed to have in minute quantity. We are very concerned. His doctor says Singulair should not cause weight gain - but after reading, I think it does. My son also does not sleep more than 7 hours/night. He says he can't. I am thinking about other options at this point.	M	9	2 years 5 mg 1X D		8/24/2010 Email
1	Asthma	I put the pieces together last night. While I was describing my 11 yr old son I was saying things like "driving me crazy", bursts of tears for unknown reason, "I don't care comments about activities that he has always loved, exhaustion, anger, When I ask my son what is going on with him all I get is tears and "I don't knows", I look at him and he just seems so sad and depressed. This is not the kid that I know.. As I started thinking about these behaviors I was trying to figure out how long this is been going on and I realized it has been happening since beginning this medication. As I was reading all these posts I started crying.. Why did I not think of this before. As a mom and a nurse, I should have recognized this. I will be talking to his doctor today and he will not be taking this anymore..crossing my fingers....		M	11	30 days 1X D		8/24/2010 Email
1	Asthma	My 5 year-old son took Singulair for about 6 months. He started Kindergarten around the same time as starting the Singulair. From being a happy, focussed little boy he became extremely violent, anti-social, un-cooperative towards his teachers. He would lock himself in the bathroom, urinate in the playground and draw violent pictures. His allergist recommended that he stop the medication immediately and it was like turning a switch, he went back to being his happy normal self again. My 12 year-old son has taken it for 7 years without incident however.		M	5	6 months 4mg 1X D		8/23/2010
3	Allergies	Dirrhea, Watery stool, anxeity, stomach pains after I ate, upper and lower back pain and headaches	Singulair worked for my allergies but the side effects were to much for me to handle. It might work is some people with no side effects but I cannot fathom taking a drug with the side effects that happened to me I mean to give you an example after I ate something I would experience stomach pains then not shortly after run to the bathroom. since coming off of the drug the side effects have gone away. I rather suffer than take this drug!	M	40	25 days 10 MG 1X D		8/22/2010 Email
5	asthma/ night TERRORS	NO side effects	My son is 4 1/2 years old, he has been having night terrors 2-3 episodes a month since he was 2. he was just diagnosed with asthma(R.A.D.) and has slept through the night ever since, this medicine is the answer to my prayers. He has also been on xopenex.	M	4	2 months 4 MG 1X D		8/18/2010 Email
3	allergies	moodiness,aggressive,angry	My son has been taking this for the past 2 months and my husband & I couldn't figure out why he was throwing temper tampers, started hitting when he got angry, aggressive behavior. He has always been a good nice kid, we figured he was going through a phase and thought it was part of his growth spurt process. More time outs & the restrictions increased. We were at our breaking points. Then I thought about the possibility of side effects from his medication. On my side of the family it is very common to have side effects from drugs,so I looked it up & thank GOD for the internet! Like other parents, our pediatrician did not warn us of the possible side effects. I am taking him off the medication & hopefully we will see results soon. I am so.... glad to have found this site and thank you to all the parents who have shared their stories. I now know we weren't alone.	M	6	2 months 5 1X D		8/17/2010
1	allergies/asthma	My son was on this medication when he was three and now again at ten. We did not realize until we put him on it this time that it was causing severe changes to his personality. He is very moody, anxiety level is high and he is very angry. He is now off the medication and hopefully we will see changes. I will never put him on this medication again. I do have to say though my daughter was on it for a year with no side effects. For some it works but for others it definetly does not. Watch closely for side effects..

1	Asthma	My son is extemely aggressive toward family members and his Mom. He jumps on her in bed and wrestles very violently with her. He is laughing the whole time, so it is not malicious; but he does act insane sometimes. He started with facial tics, eye rolling, and throat clearing a week ago, and I am very conerned that he may have these socially awkward habits later in life. After reading some of these postings, we are taking him off the Singulair today as we think that these tics may be due to this medicine.		M	5	6 months 1X D		8/9/2010
1	Allergies	Massive temper tantrums, aggressive temperment, unable to please	My 2 year old suffers from allergies and the ped. gave us this. I noticed a change in her behaviour but thought it was because of the allergies and not feeling well. The medicine worked, but she was very hard to handle. I took her off of it to see if she would go back to before, and her mood improved within 2 days. Since then, I have put her on it when the allergies act up...I can definitly say it changes her mood drastically. I will never use it again. She goes from sweet and silly to one seriously mean, cranky, irritable child. Done with this stuff.	F	2	6 months 2.5 1X D		8/6/2010
4	asthma	vivid dreams, insomnia, slight anxiety	I've taken this medicine for most of my life and it has made my asthma so much better. Before I started taking it I had to use my inhaler a couple times a day. Now I use it less than once a month. The vivid dreams are really interesting so they don't bother me. I feel anxious even when I'm not taking it, so I don't know if I can blame that on the medicine. As for the insomnia, I'll definately take not sleeping through the night over felling like I am being suffocated. Luckily this medicine works really well for me, and I feel bad for all the people who have had negative side effects because it makes breathing so much easier.	F	19	12 years 10 mg 1X D		8/2/2010
2	Allergies - to control asthma	Anxiety, anger, fear, paranoia	My daughter was on Singulair for about a year and became a different person. I didn't even make the connection with the medication, but then stumbled upon this site and starting putting two and two together. In November, I posted here and wanted to update: I took my daughter off of this medication, and slowly her behaviors changed. She is now back to her normal self. While the Dr. hadn't warned me of any side effects when she prescribed this, when I told her I was taking her off meds, she acknowleged it could be the problem. Perhaps this medicine works for some, but parents, if you start your chid on it, please watch for changes.	F	8	1 years 1X D		8/1/2010
1	seasonal allergies	Side effects started 2 1/2 years ago and were wrote off as nervous "tics". Beginning with involuntary movement of wrists. Then constant clearing of throat. Months later it was a "funny breathing" as though it was an astma attack. Now over the last week, he started this involuntary turning of the neck and head and stretching of the eyes. Said it made his eyes feel better. Took him to an eye doc for exam, everything was fine. Took him to his pediatrician who again wrote it off as a nervous tic. I stopped the meds myself and two days after stopping the head turning and stretching of the eyes stopped. His whole demeaner has changed. I have contacted the USFDA and reported the side effects that he experienced noting that I had seen this forum. They in turn said that no one else had reported any of these symptoms had been reported to them. So please if you have experienced and of these please contact them and have it recorded so that they can notify and be more	Please contact the USFDA and report all these side effects. They are telling me that they have never had these repored. I gave them this link so they could read all these posts for themselves. As a mother, I am very upset and wondering what long term effects this drug may play out later in my sons life. He is only 10.	M	10	3 years 5mg 1X D		7/30/2010 Email

1	allergies	Last night I started crying uncontrollably for a reason which should have not made me cry at all. I could not stop crying. I awoke this morning and am still crying. I feel so sad. I NEVER NEVER cry. I loathe crying and am usually very in control of my emotions. This is scary. I want to keep taking it to see if it helps my allergies, but don't know if I should. I feel I will just cry my way through work today. This is so unlike me.		F	49	3 days 10 mg 1X D		7/20/2010 Email
1	asthma	I posted a rating earlier this week about feeling depressed, anxious and even suicidal while on this medicine. I have not taken the medicine for 3 days and the suicidal thoughts are completely gone. The last 2 nights I slept through the night instead of waking up numerous times. I am so glad I am off this medicine.	My brother-in-law has taken Singulair for quite a while now and has not had any bad side effects. So it does work for some people.

1	Seasonal asthma	Mood swings, lower frustration tolerance, easily saddened, throat clearing, humming, eye rolling, head turning	We started our 4 1/2 year old son on Singulair per pedatrician suggestion due to seasonal asthma. Previously we treated him with a nebulizer (zoponex/pulmicort) as needed. Our pediatrician suggested Singulair as a daily remedy so we started him on it once the school year ended (first week of June). During the first two weeks we noticed some behavioral changes (easily frustrated, VERY emotional, intense play) as well as sporadic humming, mostly while he would be engaged in watching TV. When we would ask him why he was doing that he would say "I don't know; it makes me feel better". This then led to a persistant throat clearing the following week and now, out of the blue, he has started repetitively turning his head as if he is looking at something next to/behind him. This is now happening in a wide range of environments (watching TV, playing, walking, during conversations). He says it "makes his eyes feel better". Once the head turning began, and we looked at how these symptoms had developed, we determined that this could have something to do with the Singulair so we immediately took him off. It has been over a week now and he continues to repetitively turn his head, sometimes as many as 15-20 times a minute. Needless to say we are a bit concerned and are hoping that this decreases over time since these behaviors seem to result from his 3 week Singulair trial. Updates to follow...

1	asthma	I was not to tell any difference in my asthma. However, my thoughts and emotions were greatly affected. I have been having suicidal thoughts and even planning it. I have been having terrible mood swings. I snap at the least little thing. I am glad I finally realize it's this medication.		F	44	2 months 10mg 1X D		7/6/2010 Email
5	Asthma	None	I love this medication. I have been fortunate not to experience any side effects and have had lots of benefits. My asthma is never better than when I am on Singulair and it knocks out my allergies which are a main cause of my asthma. My mother had temporary depression when she started this medication but I never experienced that.	F	28	3 years 10mg 1X D		6/30/2010
2	allergies and cough	weight gain, mood swings, manic behavior, nightmares, and anger	great with allergies but the side effects are worse than the allergies.	F	47	3 months 5 mb 1X D		6/24/2010
1	Allergies	I have been unusually depressed - suicide thoughts - lack of mental acuity. Also, primary reason I took this was to get rid of a cough but I cough every time I breath cool air from air conditioning. Also experiencing breathlessness at times.	I went online to see if my depression could be associated with any drugs I am taking. I also take blood pressure medicine (losartan) but have not had any problems with that in the past year.

1	tighness in throa	Immediately felt anxious, pounding in chest, and appox. 4 hours later my left arm was tingling. I felt "fuzzy" headed, not happy will not take another one again.	Would like to know how long it takes to get the 5mg's out of my system.	F	46	1 days 5 mg 1X D		6/23/2010
2	allergic rhinitis	unusual weight gain, unexplained anxiety	While overall, the singulair increased my air flow at night to help me sleep better, I have experienced periodic bouts of anxiety for no reason. I have also had unusual weight gain in a short time (when usually pretty consistent)which I have seen mentioned at length on other sites, and is not a listed side effect. Please note too that the children's formula contains aspartame which can lead to many of the side effects I see listed.	F	43	4 months 10mg 1X D		6/16/2010
5	Asthma, bad cough, chest infections	NO SIDE EFFECTS WHAT SO EVER.	My 4yr old son suffered year after year with asthma, a terrible cough and chest infections. Each year would be worse than the other. He has been on 4mg once a day for the last 2 months and it has been the best 2 months of his life health wise. I have keept a very keen eye out for side effects and can honestly say, there are NONE. I will take him off Singulair in the summer months when there are no symptoms. But will put him back on when symptoms start up again. This drug has been a blessing for us I just wish it could be this way for eveyone else.	M	4	2 months 4mg 1X D		6/13/2010
2	allergies	wild mood swings; manic behavior; hysterical crying	Our Ped. Prescribed Singulair for our daughter in addition to Zyrtec for constant allergies, post-nasal drip, and mucus. When a 4-y.o. comes to you and tells you that she had a "freak out" in school, you know that there are problems. Each night at home she would burst into tears hysterically and scream on the top of her lungs at the drop of a hat. The episodes would last about 20 minutes. The moment I stopped the meds, her behavior went back to normal. It did help her sinus issues, but the side effects were not worth it. Reading all of these comments makes me realize that I was not imagining this as my Ped. suggested. Thank you for your posts.	F	4	4 days 4 mg 1X D		6/13/2010
1	allergy	irrability, focus on suicide, self harm, change in mood, nose bleeds	We have a 16 year old son, who has no history of depression or unhealthy ways of coping. Started a downward spiral, we did not know what was going on. He could not explain it,"I don't know" Took him to counseling for help, they did not have an answer, or see something we couldn't. Read an article on singlair, and was outraged and shocked, never Knew there was a possible connection. Stopped the medication. Waited... THe next day, our son was back. Each day was brighter and brighter. Would not have believed it, unless lived it. Have it documented by counseling as well. Hoping to follow up with someone who can get the word out. Our son's life was saved, and we would like to help others. Thank you	M	15	1 years 10mg 2X D		6/12/2010
5	allergies	None	OMG, I can not believe all the bad things I'm hearing about Singulair. I have been on this medication for two years for allergy season and it works wonderfully. When I got sick it took me a while to go to the doctor, which made my allergies even worse, but within the first week I started taking it I notice the difference. I breath better, I don't have any allergy symptoms and I sleep well at night. My bf has asthma and it works for him also. Are you sure you guys are not exaggerating? I work at a pediatrician office and most of our asthma and allergy patients are on Singulair and I have not heard any complains. The patient's parents like this medicine. I know that every medication works different for everyone. Some medications work good for some people and for others they have nasty side effects but are you guys sure that yall don't have something else going on in your lifes that is making you guys depressed and act crazy!?.	F	23	2 years 10 1X D		6/11/2010
2	Asthma	Emotional outbursts, flooding of thoughts, joint pain, racing heart, spaced out, insecurity and negative self talk, suicidal thoughts, hopelessness.	Singulair did a great job on the asthma it was the other crazy side effects that took me over the edge. Used to be on 10 MG and am down to 2.5 and hope to be off of it soon. I spent thousands of dollars on therapy, counter balanced these side effects by taking more drugs: Adderall (ADD Drug) for the spaced out and inability to focus, VIOXX for the joint pain, bursitis and aches (until it was taken of the market), COUNTLESS natural remedies running me thousands of dollars. Currently I am detoxing and drinking Kangen Water. The Kangen water has been most beneficial for my breathing and detoxing whatever was giving me the asthma in the first place.

1	allergies, chronic sinus problems	Facial tics, body tics, very emotional, aggressive behavior	While taking Singulair my son was 5 yrs old and became very emotional, he would cry at the drop of a hat over the smallest things. He also had sudden aggressive outbursts, which was not like him at all. He also developed several facial and body tics that soon became very severe to the point where he wasn't able to stop and couldn't function in normal daily activities. Within less than 24 hrs after taking him off of it we saw improvement of about 95%. I would not put any of my kids on singulair again, it's not worth it to us!! I highly recommend that any parent considering giving it to their child weigh the benefits and side effects before giving singulair to them.	M	5	3 weeks 1X D		6/7/2010 Email
4	allergies/asthma/persistant cough	My son has not had any of these side effects.	My son still has a post nasal drip cough but it is much better than it used to be.

3	Asthma & Seasonal Allergies	Aggression, Mood Swings, Depression, Suicidal talk, Hostility, Irrational, Not caring about consequences, uncontrollable rage	My son has been on this for a yr & we have noticed a tremendous change in him but we always blamed it on Zoepenex for his wheezing. I feel that the Singulair has controlled his asthma & allergies but we are about to seek help from a psychiatrist for his awful behavior. We started to read the side effects & are wondering if this is the problem. Met w/ his Asthma Dr. who says "maybe" & she recommended stopping it to see. We have decided to wait until the end of June when the pollen season ends. It's a catch 22, b/c if he wheezes off of it, then Zoeponex creates its own problems. I'm scared to see him have an asthma attack but I am very worried about my family. This situation is affecting all of us. We can't take it anymore!! Will report back soon what happens. He was never like this before all of these meds.	M	5	12 months 4mg 1X D		6/1/2010
1	Asthma	I took both Singulair and Accolate which is in the same class of drugs when they first hit the market. I experienced tingling in my legs, visual changes, and memory loss. Everything but the memory loss resolved as soon as I stopped the drug, the memory loss gradually improved over a year or so but I'm convinced impacts me to this day. Clearly it wasn't worth the side effects, but the drugs made me 100% symptom free from my asthma.		F	36	1X D		5/28/2010
2	allergic rhinitis	sore throat, vomiting, decreased appetite, increased aggression	My 3 year old son commenced on singulair as a trial to reduce the allergic rhinitis. Discussed with his doctor today regarding behavoural changes and possible side effects. He was not aware of behavioural changes with this medication. We agreed to stop the medication as I feel it is affecting his mood and at times uncontrollable rage. I also think is appetite has decreased. I do not believe this is 'age related'.

4	air constriction	Heavy coughing if one dose is missed	I've read many of the comments and it looks like my son will be one of the lucky ones. No mood changes, is doing great in school, sleeps well. The only anger problems we are facing is with our 2 yr. old who is not taking any meds. but has had a change in grandparents who watch him for us. So don't be so quick on the meds check who they may be exposed to. But I will take him off the meds for the summer so the body wont have long term effects such as the liver.

In the 2-3 days after stopping, all side effects are resolving and I have been peeing out this extra fluid endlessly.		F	41	21 days 8 mg 1X D		5/22/2010
3	seasonal allergies	First year: Singulair with Nasonex - no notable side effects (6 month period). Second year: Singulair with Flonase generic - in 4th month of use I started waking up with feelings of depression that would not linger after I was awake. I can not be sure that the depression was caused by Singulair. I weaned myself off Singulair in a week and continued taking Flonase generic. A week later I noticed that my mental capacity had improved. While on Singulair I had difficulty in the evening getting motivated mentally to do anything, and also found it difficult to concentrate on complex tasks (computer programmer). The week after getting off Singulair I noticed a significant change. My mental capacity returned to normal (in the evenings: ability to focus on complex tasks, motivated to perform problem-solving tasks).	This is the second year I have been on Singulair. I wuuld start in February and take it til around August/September to treat tree and grass allergies. The first year I started in late March, but did not notice any side effects; I also used Nasonex; Singulair was not sufficient by itself to deal with my allergy symptoms. The second year I switched from Nasonex to a Flonase generic. Without Singulair and a steroid nose spray during my allergy season, I was unable to concentrate during the day (fuzzy, floating feeling from allergies, sinus pressure, etc), had to deal with sinus congestion, occasional sinus infections, frequent sore throat, cough, sneezing, physical fatigue, aches throughout body, and difficulty sleeping. Currently I am using the Flonase generic only. I still experience muscle aches throughout my body, physical fatigue, some sinus congestion, and sore throat, but have decided it is worth it to regain my ability to concentrate in the evening and feel motivated mentally throughout the day. Additional notes: I normally tend to have mild anxiety and difficulty sleeping, but do not experience significant feelings of depression without a cause.	M	47	15 months 10mg 1X D		5/19/2010 Email
1	Asthma and Allergies	couldn't sleep!!!!!!!!	It helped some of my congestion but I didn't really see much of a difference with the asthma. Never had problems sleeping at night, but on this medicine I did. I took it at night, and I couldn't sleep. Out of the 4 days I took it, I would get 3 or 4 hours of sleep every night. The 4th day I took it, I didn't sleep AT ALL and couldn't fall asleep during the day. I didn't take it the next night, and slept perfectly. I didn't wake up once during the night.

3	asthma	worked great for asthma, but then I began having leg cramps, at first mild, then severe, had to stop taking singulair	Has anyone else experienced severe muscle cramps while on this medication? I am just wondering if others are having leg cramps.	F	60	4 months 10 mg 1X D		5/13/2010
2	allergies,asthma	worsening of asthma, more frequent asthma attacks, mood swings, change in personality, depression, sleeping issues	My doctor prescribed this medicine for my allergies and asthma. Within 2 weeks my asthma worsened. I was having more frequent attacks and my overall breathing went down hill. The more I tried to sleep, the worse I felt. On top of that my moods began to change quickly and without much reason. There were multiple times I would snap and be verbally combative with my boyfriend with little or no prompting. Other times I suddenly felt very sad without being to pinpoint any reason and could not hold myself together. Crying bouts and inability to deal with fellow employees at my workplace sky rocketed. The mood swings and freakouts also contributed to more asthma attacks. Before taking Singular I had been aware that it had some negative side-effects in children. I had no clue that adults had also had problems with it. I have no doubt this medication works well for some people. According to the labeling most people can take this medicine and reap the benefits without negative side effects. For those of us that it does NOT help, it's a very serious matter. I have discontinued use TODAY after my doctor realized something was wrong after the my last meltdown.	F	21	1 months 10 1X D		5/12/2010 Email
2	Allergies & Asthma	Depression & Anxiety	Took Singulair on and off from age 13-16. I never really took the meds consistently until my sophomore year of high school. I was also depressed and anxious that year. I would break down crying twice a week to almost every day. I don't think it was 100% because of the medicine, but it may have contributed to the problem. I stopped taking it and the depression went away around the same time.	F	18	3 years 10mg 1X D		5/6/2010
1	Protective med against flu sideeffe	Violent aggressive n mood swings for my 2.5 yr old like I had never seen before.

1	allergies	Prevously took 5 mg on & off for 3-4 year, but when dosage was bumped up to 10 mg, had major depression, suicidal tendencies, lack of concentration, poor vision and trouble relating to family and teachers. After reading these reviews I am going off today & hope these side effects disappear.		F	13	3 months 10 mg 1X D		5/3/2010
4	allergies	vivd dreams, minor drowsiness	Singulair has worked really well for me. It really helps to open up my airways. I take it in the evening, and I only experience minor drowsiness. The vivid and unusual dreams are actually really interesting, so they don't bother me at all. I think people need to realize that drugs will work differently in people, so not everyone will experience the nasty side effects. I love singulair and plan to keep taking it.

1	Exercise Induced Asthma	HORRIBLE side affects - racing heart, severe anxiousness.....lasting days after stopping! Probably did not take it long enough to notice any improvements to the asthma. HATED it - can't wait for the side effects to STOP.		F	40	2 weeks 10mg 1X D		5/1/2010

1	allergies, ear infs, congestion	Drug was very effective with no side effects until about 3rd - 4th month when I realized I had become depressed, anxious, irritable, easily agitated, and easily angered with no to little motivation which was very atypical for me. Could not find a reason for it.	Kept forgetting to pick up my refill so I rationed the remaining pills, taking one every couple days for a week and then went without for approx 5 days. By the 5th day having no singulair, I suddenly realized that I was back to normal with no depression, anxiety, etc. Will never take this drug again and hate to think what condition I could have been in had I continued on it any longer. So glad I found this out purely by accident. Am amazed at the very negative side effects and never suspected Singulair as the cause.	F	55	5 months 10 mg 1X D		4/23/2010 Email
1	allergies	eye and neck twitches	My son just started taking this medicine last Thursday. So, its only been 7 days and yesterday and today I noticed he would turn his eyes all the way to one side or the other several times and then stop. I asked him if something was bothering his eyes and he said yes but he couldn't explain what the problem was only that he couldn't help it and couldn't keep from doing it. He was only supposed to take for a month to get through the spring pollen season here. But, I'm not giving it to him anymore now that I realize the singulair is the problem. I asked him how long his eyes have been bothering him, he said it wasn't bothering when he went to the doctor, but now it is. He's only 12 and has enough to deal with just being in middle school. He says he's been sort of embarrassed by the problem. I hope stopping the medicine will end the side effects.	M	12	7 days 5mg chewab 1X D		4/21/2010
2	Allergies / Asthma	My 8 year old son has been on and off Singulair for approximately 3 years. As far as relieving symptoms of seasonal allergies and asthma, it does a great job. At times, he has a difficult time with concentrating in school, mood swings, eye and head tics / twitches, crying at night, worrying about his grades, etc. I have noticed when we get off Singulair for a week or so, these symptoms subside. Not sure what to do!! There has to be another drug out there that has the positive benefits as Singulair without these scary side effects!		F	38	3 years 5 mg 1X D		4/20/2010 Email
1	Allergies	Within 24 hours, my even tempered 3.5 year old turned into crabby, crying, emotionally fragile child. He would melt down in tears and when asked what was wrong would say "I DON'T KNOW." He is usually very good at expressing himself, but since being on this, he is easily upset and confused.	When he wakes in the morning, I'm telling him he doesn't have to take this anymore. I had a bad feeling going into this...no reason why as I had never really heard anything about Singulair (positive or negative)...I just had a bad feeling. I feel so terrible that my sweet boy has had such a difficult few days (major tantrums/meltdowns). He's 3.5 and I'm proud to say that I am always complimented on how lovely he behaves...not the last four days...poor sweet boy. I can only imagine it's the medicine. He has only been able to express that he feels bad all over, but cannot pinpoint an exact location. He said he felt fragile and very sad for no reason at all...scary stuff.

4	Allergies	Vivid dreams but nothing horrible. I guess it all depends on what skeletons are in your closet.	Seems to work fine. my 6 year old daughter has taken it with no side effects. As with all new medication theres a bit of anxiety about taking it. I see alot of bizarre psychological issues on this board like aggression and even masturbation but those sound more like behavioraly issues. Ive never seen a drug force someone to do anything any. Can it make you irritable ? sure, some may but Ive seen no side effect from it yet.	M	36	1 months 10MG 1X D		4/19/2010
1	allergies	Angry, moody, tantrums, never happy, never smiling. Frustrated easily. Fighting constantly with sister and family...now even grandparents, aunt, etc.	My son has been on and off Singulair for years. When he was off in the summertime, I had my son back. After reading this site, I am thrilled to see that there might be a reason for this unbearable behavior. He does very well in school and this problem does not carry over there. So, I didn't attribute it to the meds. I am taking him off today and will be patiently waiting for a change!	M	6	3 years 5mg 1X D		4/17/2010 Email
1	allergies	head twitches/tics	My son starting taking Singulair on and off since January. I started giving it to him REGULARY the last week of January til about a month ago. What he experienced/now experiencing was/is head twitches. It was like a twitch to the side of his head, all day long for a month now. It was a ped on call that asked if he was taking singulair and said taht it was known to cause tics and twitches. He has been off for a month now and although the twitches has subsided they are still very-much-sothere. I plan to leave an update with hopes that I can help someone else out becuase I am claiming the victory over this medicine. To see my son go thru this has caused a major depression for me and has affected everything that I am involved in. But as I pray, I KNOW all will be well and that it will just take time for this drug to pass through his system. God Bless you all and I feel your pain.	M	8	3 months 1X D		4/17/2010

1	seasonal asthmatic symptoms	mood swings, night terrors, nightmares, anxiety attacks, agressive behavior	I actually left a comment back in December about my 3 yo taking the drug Singulair. I wanted to update, because I know that responsible parents are checking these sites hoping to learn more about the medicine! My son was actually diagnosed with post traumatic stress disorder after only being on this medication for FOUR DAYS! The hallucinations he experienced while on it kept him from sleeping in his own room for FOUR months, and we actually had to switch his room to a different room, completely redo the paint, covers, furniture, everything. It was a NIGHTMARE. Finally, four months later, he is returning to his old self. We actually have switched pediatricians because she again prescribed Nasonex after knowing everything we went through with Singulair...sure enough, the side effects are the same. Parents, please take caution. These are adult drugs they are giving to children.	M	4	4 days 1X D		4/10/2010 Email

A lot of people commenting here are doing what patients on a new drug often do: attribute every negative feeling and symptom they're experiencing to a drug they recently started taking.

They get colds that move to pnemonia quickly. I must say, they haven't been sick at all since being on medication. They are usually sick every other week. But, they have been fighting with eachother and us (their Mom and Dad) from morning till night. Hitting me, throwing tamtrums, irrational, and moody. They are NEVER and HAVE NEVER BEEN like that.

1	allergies/asthma	Aggression, tantrums, moodiness, tired, not listening, crying	My son has dealth with postnasal drip and asthma that comes on during the middle of the night since he was born, we saw a new pediatrian 2 weeks ago and she said 'your son has allegies and needs to have his asthma under control' and prescribed singular. At first I was so happy to finally have some answers and a 'solution' but boy was I wrong! With in 2 days of taking this medicine, my son who is my mellow child and very caring and loving started throwing tantrums like i've never seen any of my children do, he was agressive, would not listen to me or his father, then after a couple more days started hitting his sibblings, punching them to a degree more than 'normal' sibbling playing around. I then looked closer at the side effects of the med and saw 'mood behavoirs' listed under 'possible side effects' ok I thought it would maybe level out after 2 weeks on the medicine. While the screaming tantrums have mellowed out, the other things have not and finding this site tonight seeing the other comments, confirms my resolve to not give him anymore Singular. I have my sons 6 year check up in 3 days with his usual pediatrician and I'm going to give my complaint to him about the side effects of this medicine.	M	6	14 days 4mg 1X D		3/27/2010

I notice the first few hours (2-4) I take it I can feel my allergies lessening, but the effectiveness against allergies seems to go down after that. During these first hours I also feel the strongest side-effects, light headed/zoned out, etc. I've only been taking it for a few days now, if the side effects continue to be as strong as they are with the limited benefits vs allergies I'm going to discontinue usage.

The rx helped with my daughter’s allergies.For 5 yrs we have been dealing with behavior problems,separation anxiety,school anxiety,anger,low school grades and depression,comments like she wished she was never born/wishes she would die.Until, Feb 2009,I had to start homeschooling because the school anxiety had gotten so bad.I then began to notice that she was doing strange things that eventually became apparent that she was having seizures. We went to the Neurologist, which he discovered that she had a brain tumor.Which a lot of these behavior issues could have come from problems related to the tumor and seizures.She had the tumor removed in July. She started Keppra for seizures. Well, not many of the problems went away. So,I was told that some pt’s with seizures has mood disorders. We have been trying different medications that are for seizures and mood disorders.So far nothing has helped.Instead of starting another seizure medication that has tons more side effects than Keppra (that has worked well) I decided to look at the side effects of her allergy medication.This was the first site I came to and I feel terrible. It's been two weeks since I stopped given her Singulair.It's amazing in the difference in her behavior, attitude and schoolwork.	F	10	5mg 1X D		3/17/2010 Email History

I "googled" singulair hyperactivity and this site came up with other parents saying almost the same exact thing. We are going to the doctor's office tomorrow regarding this.

It may have negative side effects for some children, but you won't know if it helps unless you try it. My son has been taking it in fall/winter over 2yrs. It is very helpful for his coughing at night and allows him to sleep. We saw very mild increases in agressive behavior, but nothing we can't live with for the moment. I think this medication can affect different kids differently.	M	3	2 years 4MG 1X D		3/11/2010

1	Asthma	Behavioral issues such as defiance, hitting, kicking, screaming, trouble sleeping, raging tantrums, hitting himself	My son has been on singulair since he as one. He is now 3. I have spent the last two years trying to figure out why his behavior is the way it is. He has been kicked out of 2 different day cares for hitting other children, throwing toys, throwing chairs, knocking over tables etc. He can go from being perfectly fine to raging like this is 2 seconds. I have had him evaluated and everyone says it's just his age he will grow out of it. In the mean time, he was recently kicked out of another day care. After reading the Singulair website, I asked his pediatrician if this could be the issue, she said no. Yesterday I found this site and after reading all the other comments from parents with similar problems, I have stopped the Singulair. I have no idea how long it will take to get out of his system.

It worked but not well. I remained stuffy when I went outside. I ended up having to go into surgery to get polyps removed from my sinus cavity's 3 weeks ago. My DR put me on Singular to help relieve the sneezing and to help relieve my allergies for the spring/summer {I didn't know that even in March there is pollen in the air coming up from either the south/west}. I am happy about getting singulair it means that I won't be suffering this summer; for the first time in about 2 years. Hopefully it will help reduce the build up in my sinus cavities also. Along with that I was put on nasonex at the same time.	F	25	4 days 10MG 1X D		3/6/2010

I have noticed increased irritability and moodiness in my 6 year old daughter. It seems to be worse in the morning and evening. She seems fine at school, but with her sisters she is looking for a fight. She is the baby of the family and somewhat spoiled. This is still not normal behavior. We are stopping the med tonight.

My 7 year old, 5 year old and 4 year old are on singulair. After reading everything posted on this cite I now have a new insight into my two middle children. My oldest has been on singulair since he was 3 and has no problems with it in the 4 years he has been taking it. When the doctor recommended that my two other boys take it I figured no problem. I was wrong and they will be stopping it tonight. My five year old is wetting the bed, crying all the time, acts depressed and has dark circles under his eyes. My four year old is a completely different child. He screams all the time, has no respect for anyone, is constantly fighting with his brothers and has complained of his legs hurting. He was the sweetest child I had. I used to joke and say he was my angel from God because his older two brothers were driving me crazy. I could not figure out what happened to him. He is fine at school and as soon as he gets home he is a different child. We are now discontinuing this medication for two of our boys. For now my oldest will stay on it because he has severe asthma and it helps him.	M	5	6 months 4mg 1X D		2/26/2010

The side effect is gone now and it has been two weeks since he has stopped taking singular.	I have taken Singular for a couple of years with no problem.

3	Asthma	Bed wetting, excessive talking, night waking, nightmares, aggression toward the dogs, hyperactivity. My son can just barely stay out of trouble as it is. Sometimes we have to go back on the singulair so that he will stop coughing and wheezing. When we do, we see his behavior get much worse. It takes a couple of weeks to really start working and about the same time the coughing stops, the talking starts. He will jabber out loud so fast my husband puts in ear plugs. We have to weigh the asthma symptoms to the amount of trouble he is causing.	My son has been on and off this drug for 4 years. When he takes it he stops coughing and wheezing it works really well. It is good and bad.	M	6	4 years 4mg 1X D		2/22/2010
1	asthma and allergies	severe anxiety, hullucinations, paranoia, severe mood swings.	Started taking this in 4th grade, worked great for my allergies and asthma, however when the dose was upgraded to 10 a year later I started getting hullucinations, was very paranoid and scared. I took the medication on and off for five years so there would be times I would be fine then I would start in with major anxiety, fear, afraid all the time that my mother was going to die, unable to do anything away from her. My mother asked the doctors if these symptoms could be related to Singulair and they just dismissed us and said no. My symptoms got so bad I was given prozac and xanax, which didn't help. Then we found this site and stopped taking the medication immediately. That was two months ago. I'm almost free of the anxiety, not completely symptom free but feeling MUCH better. I'm able to go to school and even out occasionally with friends. This medication works for the allergies and asthma symptoms but not worth all the horrible side effects. I wish there had been better warning labels when I started this medication, I would have stopped it immediately back in grade school and I believe my life would have been much different.

1	Congestion from allergies	uncontrolled urination & bowel movements; nightmares, inattentativeness at school; moodiness; slight aggressiveness; sleep walking	My six year old son was on the medication for about three weeks before the abrupt changes in his personality. The first indicator was a phone call from his teacher very concerned with the unexplained "accidents" he was having at school. This was very unlike my son considering that he never had any type of "accidents" since he was potty trained at two years old. My son's teacher also described my son's inability to concentrate and almost an unwillingness to do his work. The potty "accidents" continued at home with almost a daily occurence. I began noticing a change in his level of moodiness and aggression. Unhappy with a conversation I was having about him with his grandfather, my son hit me with a plastic toy bat. What was alarming was the action, not necessarily the force. The straw that broke the camels back was when he was caught sleep walking. He ended up in my kitchen, removed his shorts and underpants and urinated on my dining room chair and kitchen floor. He was completely unaware of the incident when he woke up later that morning. It wasn't until I connected these changes to the onset of putting my son on this medication. I passed along my concerns to his pediatrician who merely dismissed it as a change in his diet and now having a sleep walker on our hands. Her advise was to bulk up his diet and to put gates and bells around the house to awaken us if my son continued to sleep walk. I know my son, and I know his behavior patt	M	6	1 months 4 mg 1X D		2/15/2010 Email
1	Asthma	When I first started singuliar, my asthma improved for the first few weeks, then my asthma went back to the way it was, I would have an attack at least once a day. I thought, why take this medication when I am having the same amount of asthma as before the singulair. After a few months on it I decided to stop taking it, my asthma became severe, like I would have an attack every 3 hours and use my albuterol. I gave up, now have been on it for about 2 years. Tried slowly weaning myself off it, can't seem to. I just stopped cold turkey two days ago and my asthma is out of control. Also, doctors have had me on steroids my entire life, as I got older, I would get sick more often and more severe. Sinus infections, broncitis, pneumonia, many times a year. I stopped all the steroid inhalers and prednisone about 4 years ago, it took almost a year for my immune system to recover from the steroids, but once it did, it was great. I never have to go to the doctor for sickness, my body can fight the		F	35	2 years 10 1X D		2/11/2010

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?

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
