1	doctor recommended for asthma	CHRONIC HIVES BIG WELTS ALL OVER MY BODY, SEVERE NIGHTMARES, HEADACHES, ITCHING ALL OVER, DEPRESSION, BIG WEIGHT GAIN, BEWARE WHEN TAKING THIS DRUG YOU MAY GET CHRONIC SIDE EFFECTS LIKE ME?I was having problems with breathing for the first time in my life. I had to go to the ER about 3 different times in about 2& 1/2 weeks. They had started me on prednisone and an inhaler. The 3rd time in the ER the on call doctor was concerned and wanted to admitted me. My husband thought he was helping me out and said lets get to the bottom of this. They did and an other doctor said to take singulair and continue taking the prednisone.	That is when everything started. It has been a nightmare for me. I stopped taking the singlar but have to continue taking the prednisone to control the CHRONIC HIVES I get daily. I have had a CT scan, lots and lots of blood work. They have not found anything. I can not get off the prednisone because the hive get really bad. I am now going to a specialist who is going to try some cancer drugs to get me off the prednisone which I have been on for 6 months at 15mg a day and am getting side effects from it. Some days I don't know how I can make it through the day. But I try and I keep Praying. My husband has told me that he feels like it is his fault. I don't blame him. But he has to watch me go through this daily and it's tearing him up not being able to do any thing.( My husband which he could go back in time and never let them admit me.)After about two months I stopped the singular.

4	asthma	I haven't noticed any side effects	Works alright, but I need additional medication to control my asthma. Advair's worked best for me.	F	26	15 years		11/16/2006
5	asthma	none, zero, zip	It's a wonderdrug for my mild asthma. I have some allergies and also cold weather/exercise induced asthma. I used to have to use my inhaler after walking or shoveling snow in the winter, and before exercising every day year round inside. Since beginning this drug I have had to use an inhaler maybe 3 times when I have had a respiratory bug....that's 3 times over the last 12 years; as opposed to daily use of the inhaler prior to beginning this drug. Zero complaints!!!	F	51	12 years		10/27/2007
5	Asthmatic for 18 yrs/Allergies	Drowsiness	I came to this site looking for side effects of another medicine I'm taking and decided to see what people have said about Singulair. I was put off at the fact that someone said the only reason anyone would give this a 5 is because they work for the drug company. WELL, I certainly do not. When first prescribed, I was taking the chewable child dose (considering I was about 9) but eventually moved up to the adult 10mg dose. I've never noticed any side effect except drowsiness - which is why the bottle says to take at bedtime. It works wonderfully for me. I notice whenever I skip a night my asthma flares back up to usual symptoms and I have to take at least one dose of my inhaler. When I take it as prescribed I don't need my inhaler at ALL. It does take about 2 days for Singulair to fully work if I have missed some doses.	F	21	12 years		1/11/2008
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	asthma	SEVERE DEPRESSION, suicidal thoughts, self loathing, hated everything and everyone, hated my job, gained 30 pounds and now I find out that this terrible pain in my joints may be caused by it too???? Constant Fatigue!!!	Ive taken it for at least 10 years but NEVER made the connection with the depression, joint pain and weight gain (i mean, who would from an asthma med?)

5	severe asthma	None	It has changed my life for the better. I can now breathe and be active, walk, play golf etc. I was steroid dependent prior to taking Singulair. It has been a miracle drug for me.	F	64	11 years 10 mg 1X D		4/12/2010
3	Mild Asthma and allergies	My daugther was diagnosed with mild asthma at age 5. By age 6 she was started on chewable singulair and eventually moved up to the 10mg tablet. She has progressively gotten sicker with time. Not her asthma, but with these crazy symptoms. She was diagnosed with migraines at age 10. For the last three years her quality of life has declined so that she has only had one or two good days a week. She completely missed the last semester of the 11th grade and will have to repeat it. Her symptoms have been: headaches (cluster, migraine and mild), leg pain, rapid heart rate, chronic fatigue, rash like psorasis on her elbows at times, severe abdominal pain, nausea and vomitting, occasional nightmares, foggy thinking, hunger, and reflux, mood swings and abnormal periods.	She was recently diagnosied with sub-clinical hypothyroidism. She has started on Sythroid and after a month has shown some improvement. I took her off the singulair about 2 weeks ago after finding this site and reading about all these side effects. I don't know if the singulair is the total culprit or not but, I took her off of the Singulair to see. It may have been what has caused the sub-clinical hypothyroidism also. She has been on it for years and progressively gotten worse. She has had mutliple GI tests that have turned up nothing but this could have been the reason all along. We have been to about 14 Doctors total with the various symptoms including her Pediatrician, Pediatric Gastrointestinal Specialist, Neurologist and Allergist. She has much improved over the last couple of weeks and is starting to act like a normal 17 year old. I had even started her in counceling 6 weeks ago because of the depression she has experienced from being sick all the time. She has not had	F	17	11 years		6/13/2008 Email
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.

5	Asthma & allergies	I have been taking Singulair for 10 years or so and had first taken Accolate. I have not noticed any side effects but have had a huge improvement in my symptoms and can quickly tell if I have missed a dose. This drug has been a lifesaver for me.		F	49	10 years		8/28/2009
4	allergies/asthma		I have taken Singulair and Serevent in combination now for 10 years and they seemed to really keep things in control. I am one of these people who doesn't like to take meds everyday though. I don't want to be dependant on any drug. So I've done some research and discovered Cordyceps Sinensis (a type of mushroom)which you can take in capsule form. I purchased some at a reasonable price from Swanson Health Products online. I took it for 5 days and after some trial and error, discovered that I could go without the Singulair. Going on 3 wks now with no Singulair yippy!!! If you try this, make sure you let the Cordyceps get in your system for 5-7 days first! Good luck	F	37	10 years		3/12/2009

5	Asthma/Allergies	None that I notice.	I have been taking this drug since I was about 11 or 12, and has helped me to live a normal life. I had a gap in insurance coverage a couple years ago and went without for about two weeks. I noticed how much this drug helped me. It relieves the tightness in my chest and my throat, and I don't cough like I did. I did notice on the package a few weeks ago that this was not recomended for children under the age of 12... that might be causing the problems with all of these children whose parents have commented. If the doctor perscribed it anyways, well, it may be time to find a new doctor.	F	21	9 years		1/12/2009

4	Asthma	Fatigue,sleeplessness,high blood pressure,anxiety,memory loss,dry skin,mild depression,diarrhea,weight gain,hair loss,the start of kidney failure.	Started taking singulair about 9yrs ago when it first came out. Did wonders for controlling my asthma and still does to this day. Recently starting reading a book about natural cures. Decided to make a list of all ailments I have and preceded to do some research on there causes. Did a search for Singulair side effects and came across this site. What an eye opener. Of the 14 ailments I have written down. 11 of them can be attributed to the extended use of Singulair. I am going off this drug immediately to see if it is the cause of most of my ailments. Thanks to everyone who contributed to this site.	M	42	9 years		12/31/2006 Email
1	Allergies	Nightmares, sleeplessness, anxious, extreme exhaustion, stomach ache, depression, sore throat, palpitations, tightness in chest, couldn't think clearly, couldn't express thoughts, ringing in the ears	I have allergies that trigger horrible migraines. The first five or six years that I took this med I seemed to have no problems. Gradually something changed. I couldn't sleep without horrible nightmares, and I was too exhausted to get out of bed when awake. I would lie in bed almost paralyzed, but my mind never,ever, ever shut off. Exhaustion became so bad that I couldn't carry a laundry basket upstairs without having to stop three times and lie down for a few hours afterward. I finally wound up hospitalized for a week so they could drug me to sleep. I didn't take it in the hospital and got a bit better. I went home I started taking this, along with other allergy drugs, again, because my doc thought it was such a benign wonder drug. My symptoms all returned and I struggled for months. I had tons of tests at several different specialists to try to figure out the cause, but all was normal. I was in such a bad state after a year, desperate, I eliminated all pills, one by one. This pill was the last thing to go, because we thought it was the least likely to cause a problem. I was off it and doing much better for about 2 years. Just last week my allergies got really bad again, so doc convinced me to give this another try. I agreed, but only at a very low 2.5 mg dose to try it. Within three days ALL of the symptoms returned with a vengeance! All those years wasted and I never put it together until now.	F	45	9 years		3/24/2009
2	Chronic rhinitis	Balding, myopia, acne, aggression, and hard to focus.	I tried going off Singulair two years ago, but after taking it for so long my body seemed to be addicted. I had a large wax buildup in my right ear that got infected. Other than that I loved being off the stuff. I was insanely productive at work. The ear pain finally got to me though. I went on a quick prednisone burst and got back on Singulair. The shysters at Merck decided to raise the price again, and now that it exceeds what my insurance will pay so I am going to go off it again. I am armed with Loratadine(Claritin), pseudophedrine, guaifenesin(Mucinex), and Nasonex so hopefully I will make it this time. Wish me luck.	M	28	8 years		6/26/2007
1	asthma	my son took singulair for two weeks after not taking it most of the summer in the past few days he has become worried easily,clingy,easily upset. he has irregular heartbeat on/off and since thursday may be having vision hallucinations which is very scary to him. he is seeing black images now some white,his eye ball has alot of red lines and i'm not sure but it might have been yellow. i have been giving him eye drops for the past day cause we thought he might have gotten something in his eye. it is sometimes itchy and hurts alittle after the drops.he was feeling weak/funny, headache and stomach aches.	as i reread the side affects i see over the years it could have been singulair all a long. fevers only that last over night, nightmares, stomach aches, headaches. since age 4 he has had Pneumonia 5 times. until this past february he has been seeing the same doctor since birth. we will talk to the new doctor in two weeks. he has been taking singular since age 3 and is now 11 1/2 years old. the past doctor would not let us stop it but i have stopped in on/off until he gets the signs of getting a cold. his asthma seens to be weather related/ high temperature/mold. today i talked to the pharmacy and they said the image could be hallucinations but he has not had any one have any problems with singulair. that we could try stopping it let it get out of his system and just start back with half a pill. we decided to stop and seek info from the new doctor.

5	Asthma	Some headaches,	This medicine has allowed me to have a normal life, I am no longer living on less then %50 of my lung capacity (which I did for over a year). This product may not work for everyone, but is certainly worked for me and I think it is worth a try for others who have asthma. The small side effects are worth the overall result. I found that there were many other factors that contributed to my asthma including parts of my diet that I am alergic to (wheat, rice, and milk), I found that once I removed these from my diet the side effects went away.

2	Allergies, astma	Headaches, Numbing of the fingers and arms. Heart rate up, with palpatations. Anxiety, general weirdness feeling.	WARNING!!!! FOR THOSE WHO THINK THIS WORKS GREAT! This drug almost cured me from being sick with respitory problems my whole life that were literally life threatening. HOWEVER- long term I started getting numbing, tingling in my hands and it has always made me anxious. I am an adult. I finally figured out the cure wasnt this, it was all the food allergies i had!!! Check your blood for food allergies! A lot of the wheat soy and the rest is being manipulated and is GMO. Our bodies react to this. I got off this drug almost completely and the numbing has subsided.

1	asthma	depression, extreme anxiety, panic disorder, suicidal thoughts, loss of control over thoughts, paranoia, suicide attempt	I've been on Singulair for 7 years. It did control my asthma. However, during the time I was on it, I slowly spiraled into deep depression. After 6 years of taking it, I developed such extreme anxiety and panic disorder that I was convinced I was going crazy, as schizophrenia runs in my family. I had no control over my thoughts, which were so scary and demented that it was virtually intolerable. I had one suicide attempt year 6 of taking it. Over the 7 years I became agoraphobic. I didn't attribute my troubles to Singulair, instead believing I was mentally ill. My mom told me about the news reports and I discontinued Singulair. My doctor said to give it 1 month to get out of my system. By day 3, I noticed extreme changes for the better. It's day 11, and I haven't felt this normal since before taking Singulair. All anxiety has disappeared. I think normal again, depression has lifted. I'm dumbfounded that my "mental illness" wasn't an illness at all. I can't beli	F	27	7 years		4/7/2008
1	1st for Asthma, then for allergies	Depression, moodiness, loss of libido, loss of interest in hobbies, life etc.	After hearing that Singulair was linked to people committing suicide, I decided to stop taking it. Without doctor supervision (I would not suggest doing that), I went off it cold turkey after being on it for 7 to 8 years (I 'quit' around the end of March). I used to feel 'frozen' inside -- not temperature-wise, but emotionally. It was scary to get all this feeling back in just a few days. I've been happy for the first time in many, many years. Unaccountably happy. I had thought the emotional problems were related to circumstances and aging, which might have had a contribution. But I am on other medication that seem to be controlling the asthma and allergies and see no reason to go back taking Singulair. The change for the better in my emotional state has been dramatic and I want to stay this way.	F	50	7 years		5/22/2008
5	Asthma	none	I have been a severe asthmatic for my entire life. I was diagnosed at 6 weeks of age. I struggled for my entire life to get my asthma under control. It is only now (and after almost seven years of using these meds) that I have been able to participate in regular activities that for so long I was unable to do. I love this drug!!!

5	Severe Asthma (also allergies)	None	This has been the miracle drug of my life. I haven't been to the hospital ever since I started taking it. I have never had to go to the ER and be put on predisone or anything! Thank the makers of this drug, for it has changed my life forever! I love singulair!	F	20	6.5 years		9/20/2005
5	Asthma	None.	Because of Singulair I have not used my rescue inhaler in 6 years! Before Singulair I was using it every day. My Dr. mentioned that there's typically no middle of the road with Singulair...that it either works great for you or it doesn't work at all.	F	46	6 years		3/26/2005
5	allergies	No side effects	Has greatly helped me control my allergies.	F	57	6 years		5/20/2008
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	allergic asthma	insomnia, hand tremors, tinnitus (pulsating in left ear), pain in front of right thigh, thoughts about death	Singulair did control my asthma symptoms. I took it for 6 1/2 years. I stopped it when I read that Singulair had a black box, that it may cause suicidal thoughts in children. I asked myself what it is doing to me. I had no idea. It has been a year since I stopped Singulair. The pain in the front of my thigh went away in 3 days; the tinnitus, which I had noticed for about 6 months, lessened in 6 months and then was gone; the insomnia improved immediately--I slept so well. The hand tremors I'd had since Sept, 2005, are much less, and I only notice somettimes when I am tired. I noticed those when I would lift a fork to eat. I didn't realize I had the thoughts about death and that it wouldn't be so bad, until I stopped the Singulair and the thoughts went away. I would never take this drug again. I would never recommend it to anyone. Why does it have this effect on the brain? I tried a Flovent inhaler, but I was allergic to the propellant, according to my allergist. He placed me on Asmanex twisthaler, which is a powder, with no propellant. It has been a year and it has worked. No espisodes requiring prednisone. What a relief. And, no side effects, of which I am aware.	F	58	6 years		4/28/2009 Email
1	mild asthma	mood swings, anxiety, depression, aggression, outburst behavior, nightmares, diminished impulse control, suicidal ideation	My daughter went from a delightful little girl to a problem child almost immediately. That was blamed it on the fact that she was nearing her preteen years, though she didn't reach puberty until 14! When she ran out of the medicine recently I didn't renew it, and her behavior is rapidly reverting to normal, though her self esteem had been damaged by the years of ADD-type behavior.

She is now almost as tall as I am (5'2), she is developing normally in all other areas related to the female anatomy, I lost track of how often I have to buy her new shoes, etc.. In other words, zero stunted growth issues, zero anger issues, zero any issues detailed here. She works with a renowned Pulmonary on her asthma, who keeps a close watch on these things. I should also add that she takes this in the morning, with Claritin being taken at night. In fact, on our next visit, the Pulmonary is considering weening her off of it due to her asthma being under control and her believing she might be "growing out of" the allergies that caused the asthma in the first place. This is a child who stands close to my height and weighs all of 80 lbs. So she is built very petite to begin with. (the age and gender listed are for her)	F	12	5 years		1/6/2009 Email

5	cough-variant asthma	none	Singulair has cured my daughter's cough in 2 days! She used to cough all the time for two month after every cold she had and we didn't know it was variation of asthma. She was also describing difficulty breathing as difficulty yawning and that childish description didn't really help understand what was going on. During bad allergy season she needs some extra help (Flovent, Nasonex), but does great all year on Singulair.	F	34	5 years		6/8/2006

BUT my doctor had me start taking the Singulair in the morning instead of nightime and that worked! The nightmares went away and it's great. I do still get them sometimes when I'm very stressed out but they're minor, not like the big ones I used to get when I took it at night. Try mornings! It works!		F	45	5 years		2/27/2006

1	Asthma	Depression, loss of mental clarity, memory problems, inability to focus and concentrate, huge weight gain, bloated, look pregnant, heartburn, severe shortness of breath, lethargy, lack of interest in anything	The mental and emotional suffering - not overstated - makes singulair not worth any possible benefit. I had to leave my work because of severe shortness of breath. Have been seeing a psychiatrist who has me on antidepressants and something to keep me awake during the day. Another doctor has me on something to control the restless-leg syndrome that another singulair patient mentions. My weight gain probably contributes to my depression, and my distended abdomen probably interferes with my breathing. The 5 years I've been on singulair have been miserable. I am so thankful to have found this site. Today is April 3, 2008, and last night is the last time I will take singulair. I can't wait to see how I will be next week, next month.

1	moderate-persistent asthma	Over time, the following occurred: almost immediately began bedwetting (after being a dry sleeper); physical aggression; emotionally overreactive; irritability; gradual weight gain; always hungry; bad dreams; difficulty waking in A.M.; most recently thought he was seeing a "robber" in our house during the night (on several nights - and we don't watch scary shows) - this after a dose increase.	Our son started taking it at age 5 w/onset of moderate-persistent asthma not controlled with Advair or Albuterol. He was dry at nights from age 3-1/2 to 5; w/in 48 hours of starting Singulair, he started bedwetting at night (which we attributed to Advair). We finally moved 2-1/2 years ago to remove him from the environmental triggers, got him off Advair/Albuterol, keeping the Singulair going for asthma control. Still dealt with bedwetting all this time, but thought that had a genetic component. BUT, after a dose increase last month b/c of a flare-up, his mood & behavior worsened markedly. Mood was darker, very impatient, emotionally labile-never knew how he'd react to anything. Started wetting the bed 2x/night. We "Googled" Singulair & stopped it on 1/7/08--in 9 nights he's had 4 dry nights (the last 3 nights in a row). He stopped "seeing" a robber at night; is easier to awaken; he says he feels more awake at school and it was easier to get out of bed. He sa	M	10	5 years		1/17/2008
1	asthma	Insomnia, muscle aches, daily morning headache, feeling like ants under my skin, irritability (extreme), fatigue not relieved by full night's rest, "brain fog", inability to concentrate on difficult tasks, swelling of ankles, rash on back and legs, dry eyes, dry mouth, extremely dry lips, always thirsty, tinnitus.	I was on this med for five years, prescribed by pulmonary doc for asthma. I had been feeling increasingly tired, achy, irritable and fed up with life in general. I could not seem to concentrate at work and would make errors that I never made before. The swelling and itching and dryness was getting worse. I went to my GP and she told me I was going through menopause and was "depressed" and that I needed anti-anxiety meds. I refused to take the RX, and came home and started researching Singulair as I began to realize that the not feeling well had started the same year I was "diagnosed" with asthma. When I found this website, I knew I had to get off this drug. I have been off it for three weeks now, and I cannot believe how much better I feel already. I am praying that most of my symptoms will abate if I continue to clear my system of this drug. When my allergy symptoms get worse, I take Benadryl, makes me a little sleepy, but at least I don't have the "brain f	F	51	5 years		5/18/2007 Email
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.

My daughter has been taking Singulair for many years(she is only 11), she has been in theropy for many different problems, and we have had many different things told to us not knowing that Singulair might be to blame, she is on an anti-anxiety and an anti-depressant, she was also on other meds. for panic attacks. She has also been almost mute except at home, for years. I just found out about this and I am feeling very guilty about giving her something I thought was helping her asthma and may have robbed her of years of her life.I certainly hope someone starts a lawsuit against this company.

1	11 yr old for dust mite allergies	Poor performance at school, tearful episodes, nightmares about himself and family dying. Wanting to quit school. Poor self esteem	Ethan 11 yr. old had been taking Singulair for dust mite allergies since he was 6. Has always done poor to fair at school. Very emotional. Did not associate this with Singulair, until he began talking about death. Researched on the computer about childhood depression, found link to singulair. Described him perfectly. Although I feel like a terrible mother, I realize better late than never. I read the package insert when he was 6, but these side effects were not listed then. Since he has been off the Singulair 2 1/2 weeks now, he has been less tearful and when he does cry, it is not an outburst, hysterical cry. He has a better attitude about school; although, because of the damage already done, he will probably never like school. He is just a more rational kid. So far his allergies are not bad. He is on a nasal spray and goes for a check up in a week. I'm not mad at his doctor, I guess. She probably didn't know about the new side effects, either.

1	asthma	My son has been on Singulair for years. However, recently, they changed his dose from 4mg to 5 mg and we noticed an obvious behavioral change. He has thoughts that prompt him to be brutally honest...telling me I am fat and ugly. He has also had homicidal thoughts toward my husband and I which are followed by self-condemning thoughts. He is a very loving child and this is completely out of character for him.Looking back, we feel horrible in that he has experienced night terrors, extreme thirst, frequent urination, blurred vision, and skin dryness. We just put all of this together when the behavioral symptoms started. My husband, thankfully, remembered the news story. We have stopped taking the medication and are 2 weeks out, but still experiencing many strange thought processes. We have even contacted a child psychologist who has encouraged us to try and "normalize" the situation as much as possible. We may have to seek further help if we don't see improvement soon.

1	asthma	my daughter took singulair since she was 4...same time that my mother-in-law passed away...so i assumed the clinginess and fears were because of that...this has continued for almost 6 years when i finally figured out that her anxiety was caused from taking the singulair..	i had so much trouble getting her to school..she never wanted to leave me or even go out to dinner or ride in a car with anyone including her grandparents or cousins!!!...she constantly thought something bad would happen to her...even when i was with her at home...we saw a therapist this past year and she asked if we ever truly looked into her asthma meds? so after reading these message boards...i took her off...thank god!!! she is like a normal child and even goes to friends for playdates and never ever is worried about school and i even have her riding the bus!!! thank heavens i figured this out...but it makes me sick thinking of all the arguments i had with her while on the singulair telling her to quit acting out!

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

5	asthma/allergies	Dry mouth initially - none since then.	Singulair has been a wonder drug for me. I was living at 50 - 70% lung capacity all year, and the side effects for me of Advair and other steroids were overwhelming. I now only use my inhaler when exercizing, and previously I was using it 6-8 times per day. I do believe strongly that medications affect people differently (I was a zombie with Allegra and Zyrtec, but not with Singulair), and so have no doubt that the low ratings of others on this site are valid. I would take issue, though, with the person who claimed that the people who rate the drug a 5 must work for the manufacturer since why else would they be on this site: I came to this site because I googled whether Singulair and Claritin could be taken at the same time, and after reading the responses, felt I should add my own experiences. I really appreciate this additional information regarding the drug, and will certainly keep it in mind as I continue to use it.	M	47	4 years		10/8/2007

Went to the hospital and the attack was broken , but came back that same nite. This was going on for months for the first time in my life ( I was 39 when this happened). Usually the emergency room visit was all that i needed. Finally was referred to a pulmuary (lung) doctor ( expensive doctor but worht every penny) and he put me on a new drug called Singulair. After taking it for 1 week i was able to breath again, no more tightness and/or suffcation feelings. I still get asthma attacks once or twice every 3-4 years. I take this drug on and off, but i know when to start, when i get a cold. After i get cold or Flu the asthma follows, thats when i start taking it.	M		4 years		10/18/2005

First got it when I had four (4) pluersies in my lungs while using Advair prescribed by my regular doc. (Advair/Serovent -- dangerous drugs). The Urgent Care doc suggested I use Singulair instead along with my rescue inhaler for acute stage. Presto! I got better.

4	To control asthma symptons	singulair definitely helps with my allergy and asthma symptons. I did notice I had increased ear infections. What i have come to realize is that I have increased anxiety and mood swings. Family members commented on my mood swings and short temper. I stopped taking singulair for 3 months. Unfortunately my asthma symptoms reoccurred within a week and I had an increased use of my ventolin inhaler. However, my mood swings and anxiety returned subsided completely.

3	asthma and allergies	Singulair has worked very well to control asthma and allergy symptoms. Personally, I have not experienced nightmares or leg cramps. But read on... I have been taking it for probably about 5 years now. I am a 27 year old female, and my asthma doctor reports that the pulmicort and singulair are keeping my symptoms under control. However, I decided three days ago to quit the singulair. The doctor said on my last visit that I could try it. Here's my experience. I have had some difficulty in waking up in the middle of the night. But I usually go to sleep okay. I feel really good, though today, my third or fourth day, my chest feels heavier. I took a puff of my albuterol and the heaviness has subsided somewhat. As for the mood changes while I was on Singulair, I agree that they are a very real possibility.

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.

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.

2	Asthma	Fatigue, cluster headaches, concentration problems, weight gain, moodiness, leg cramps. Worked well for reducing asthma symptons.	Was diagnosed with environmental asthma 4 years ago. Given a six month course of corticosteroids and started on singulair and an inhaler for attacks. Started putting on weight almost immediately with no lifestyle change, increasing exercise levels did not help. Weight kept going up every year even though I exercised more and more. I was doing college courses and my work requires reviewing documents and I found it extremely hard to concentrate and focus, mood swings were incredible (I blamed it on stress at work). After reading this site, I figured I would try going off it. Almost immediately concentration levels returned and not tired all the time, weight started dropping (no lifestyle change again). Stand by when going off, I had some bad nights and sinuses went crazy for a few days. But I feel like a new person, mood swings went away. Thanks everyone! I will go back to short term OTC/other options and discuss with Dr. next visit.	M	45	4 years		8/23/2007

My son never had any of these problems until being on this rx. It is awful. The awful part is it took me 3 years to realize this is what is doing it. Please be sure you talk to you doctor before giving this medication to a young child. I have the school nurse call me regularly about him having a stomach/headache and he has missed 15 days of school this year.

He has always been on the verge of either being angry or crying. I always thought it was just him. Until he got so mad he said he was going to kill himself. It caused me to google childhood depression and I found out about this problem with Singulair. I immediately stopped the drug. His pediatician said that there could be no link between the two. Within 2 weeks, his teacher sent home a note saying she didn't know what had changed but that he was a different boy in school. Happy, well-adjusted and making friends. He skips everywhere he goes and is happy, loving and obedient. It makes me so sad that I gave him this drug for 4 1/2 years and didn't even know what I was doing to him.	M	6	4 years		7/18/2008

However, after reading the reports I decided to experiment and not take it for two weeks, and was amazed to find that my extreme anxiety and mood swings (crying jags, etc.) disappeared within a week! I had thought it was menopause symptoms all this time. Also gone are nightly painful muscle cramps, my feet and hands are warm again, and my fasting blood sugar fell by 25 points.

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.

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

I take it probably 9 months out of the year, excluding the winter when everything outside is dead. My mom and dad also take this. My mom is 53 and has no side effects.

The side effects appeared after several years of taking the medicaton and due to changes in life.	F	46	3 years		10/22/2008
5	asthma and allergies	No side effects noticed	There are three of us in our family that have used Singulair. My daughter used it when she was 5-7 years old for her asthma. She had no side effects. She had cold weather induced asthma and it really helped her. I have used Singulair for the past three autumns for rag weed allergies and it has been the miracle drug for me. I had tried everything and nothing would help. When I took Singulair, my allergy symptoms completely went away. I also have a five year old son who takes it in the spring and summer for allergies. We had tried everything and nothing would help. Again, Singulair really worked with no apparent side effects. My only complaint about this drug is that there is no generic available and it is very pricey.	F	35	3 years		5/25/2007
5	COPD	none	Since taking Singulair have been able to get through the cold weather without resorting to steroids for my breathing problems for the first time in ten years. My respiratory capacity has also improved.	F	58	3 years		6/6/2007 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
5		None	My son has taken Singulair for 3 years with no side effects. He is doing well in school and has no problems with concentration or behaviour.	M	7	3 years 5 mg 1X D		7/24/2010
5	asthma/sinusititus	None	Prior to using Singulair I was having sinus surgeries approx every 18 months. No surgeries needed since and my sinuses are gerat all the time (wow!). Singulair also allowed me to reduce my inhaled steroids to the minimum levels - asthma flares now only occur when I have a respritory infection.	M	44	3 years		7/25/2005
4	night time cough,seasonal allergies	none that i can specifically link to the drug	my 6 yr old has been taking this for 3 yrs now. the first 2 yrs only during allergy season & for the past year, through out the year. it works wonderfully, but on reading about all the side effects, i wonder if her occasional complaints of leg pain and nightmares have anything to do with it. i am considering stopping this and seeing if there are any visible behavioral and physical changes.

4	Asthma/allergies	Vaginal dryness	This is a wonder drug, it helped my asthma and allergies so much. I could breathe freely. HOWEVER, it dries me out completely, causing vaginal dryness, causing painful sex. I can't believe I"m the only one who has had this side effect.	F	36	3 years		6/24/2006
4	Asthma and Seasonal Allergies	Slightly dry mouth for 1st month	It has helped prevent sinus headaches. I now only use my albuterol inhaler when I have a cold. I used to take albuterol 2-3 times a day.	F	40	3 years		5/27/2007
4	asthma	I took Singulair for 3 years and have finally stopped it. I will say it did help, but the side effects were scary once I realized what the med was doing to me. At first, I thought there were no side effects and the medication DOES work very well for asthma. After 3 years, I finally realized that it caused panic attacks an anxiety. I also believe it has caused me to gain about 10-15 lbs. Once getting off, my body went through withdrawal (allergies flared up and I felt tired). I'm taking Allegra until those symptoms clear. Also, for you ladies out there, I really believe that my Loestrin (low dose birth control pill) is helping my breathing. We'll see what happens.	Works well, but has hidden side effects.
