About Singulair

Singulair is taken to prevent and treat asthma. The oral tablets are for asthma patients age 15 years and older, and the chewable tablets are for pediatric patients 2 years of age and older. Do not take Singulair to relieve an asthma attack. It is not a replacement for the quick help that short acting inhalers provide during an asthma attack. It is very important that you continue taking your other asthma medicines unless your health care provider tells you to stop.

Precautions for Singulair

  • It is very important that you continue to take your other asthma medicines unless your doctor tells you to stop.
  • If your asthma is made worse by aspirin, you should continue to avoid aspirin or other non-steroidal anti-inflammatory drugs.
  • Phenylketonuric patients should be aware that the chewable tablet for Singulair contains phenylalanine (a part of aspartame).

Side Effects of Singulair

  • Feeling tired
  • Fever
  • Stomach pain
  • Upset stomach
  • Intestinal upset
  • Heartburn
  • Dizziness
  • Headache

Reports of patients’ experiences after Singulair became available include:

  • Allergic reactions including swelling of the face, lips, tongue, and/or throat, (which may cause difficulty in breathing or swallowing), hives, and itching. Stop taking Singulair and call your doctor if you experience any of these symptoms.
  • A rare condition, that includes a combination of certain symptoms which do not go away or get worse, including a flu-like illness, rash, pins and needles or numbness of arms or legs, and severe inflammation of the sinuses. These have usually occurred, but not always, in people whose oral steroid medicines for asthma were being gradually lowered or stopped. Although Singulair has not been shown to cause this condition, you must tell your doctor right away if you get one or more of these symptoms.

    Singulair and Side Effects

    You are not imagining things if you believe your meds are causing serious side effects. I was diagnosed with COPD in October of 2007. Singulair was the meds of choice for my doctor and I began taking it while hospitalized. I was never a 'thin' person, but my weight was easily under 120 most of the time. I did not stop working out, and was serious about limiting my calorie intake because I knew additional weight would make my breathing more difficult. Since October of 2007 I have gained 60 pounds. I have dieted with every conceivable diet, stopped drinking soda, cut out sugar, flour, breads, potatoes. I workout sometimes 2x a day and yet the weight has increased, rather than decreased. Thyroid tests show have had all normal results. My new doctor had me stop taking Singulair 2 weeks ago and I have just begun to see and feel the difference in my weight. Unfortunately, it did assist with breathing, but I am confident the weight loss will offset the meds. I am using Spiriva now, and am hopeful my breathing will continue to improve. Never let a doctor tell you a medication 'absolutely cannot' cause a side effect. No one knows your body like you, and if a condition did not exist before you started taking a particular medication but exists now...you can be pretty sure it is caused by the meds. yes, there are studies and tests, but none are foolproof. Trust your instincts!!


    would rather live will allergy and sinus pain than weight gain

    I've started taking sinuglair for seasonal allergies and awful sinus that was no longer responnding to otc's. I've notice increased appetite and bloating as well as weight gain in my mid section. I started Naturally Slim about 5 weeks ago and I had started losing wieght and had so much energy. I'm 4'11" and before starting NS program I weighed 137 and lost 7lbs in 5 weeks, in the 12 days that I've been taking singulair my weight has stalled and the progress I was making is now frustrating me because I was doing something to get myself healthy and now with this drug it has ruined my efforts. I would rather sacrifice the pain I went through with my allergies than to jeopardize my health and increase my already high chances of diabetes. I stopped singulair after finding many posts of weight gain. It has soduim as one of the ingredients which naturally causes weight gain. I will repost on my battle with the weightloss post singulair.


    Don't Give Singulair to Your Children!

    I went with my 4 years old daughter to a pediatric allergist due to her pediatric found problems in a blood test. The allergist prescribed Singulair 4mg, Allegra and Nasonex spray. About 4 weeks later started an Allergy in her body and their pediatric said it was an Urticaria (hives) due to the food, after several test she was hospitalized for a week a received a lot of steroids and a the diagnostic of allergy to the wheat flour, eggs and cow milk with a very restrictive diet. The recipe to our home was continuing Singulair, Allegra and Zyrtec. The urticaria come back again, her lips get very red, mild fever, sweating, heat in the body, pain in the legs and the urticaria changed to a big problem, the leukocytes count down for about two weeks (leucopenia). To resume this "medical enigma", and after several weeks almost desperate thinking in everything as possible cause, my wife and i stopped the Singulair and Zyrtec (the urticaria started before of Zyrtech) and in this moment we have two weeks without urticaria and all symptoms are disappearing.

    Weight Gain Despite all attempts

    About 3 years ago, my weight started to creep up. At the time, I had never been over 120lbs on my small 5'2" frame. When the scale hit 125 despite diet and exercise, I went to the doctor seeking answers. I was convinced it was my thyroid. All tests came back normal. Over the next 3 years my weight continued to creep up. I made changes to my diet, joined a gym, started new exercise programs, nothing was working. Some had suggested it was my birth control pills so I even stopped taking those. I never made the connection until now that this all started about the time I started taking Singulair for seasonal allergies. I neverthought my allergy medicine would have such a drastic impact on my life so I just kept trying to find other causes for it When I first started going to the doctors at 125lbs they all just told me to diet and exercise. If one more person tells me to diet and exercise I am going to punch them! I am making these visits telling them that all diets AND exercise programs have NOT worked and not a single one has taken me seriously. They have done bloodwork, found nothing "wrong" and then tried to explain the food pyarmid to me. UGH! So Frustrating! I used to snack ALL of the time and now I barely snack. I eat healthy home-cooked meals most of the time, and when I eat out I go for low-calorie smaller portion options. I used to just eat whatever I wanted. I even quit drinking soda (big for me, I used to have 2+ cans per day!) and I STILL have put on 25 lbs since I quit soda! Now 3 years later I am at 150 lbs and feel bloated constantly. I go to the gym at least 5 times per week, although was exercising at home...I even started jogging on my lunch breaks at work (1 hour!) and nothing got the weight off, if anything it just keeps creeping up and up. I have been to at least 6 doctors and they all look at me like I am nuts. I even went to one doctor complaining about my efforts to lose weight and how NOTHING will get the weight off and then at the end of the session he mentioned to me that based on my height/weight I am overweight so maybe I should look into that! HELLO?? Was he even listening the past 15 minutes that I ranted to him regarding my visit?? Another problem I developed was chronic constipation, so I even went to a gastroentenologist who ruled out all factors so he recommended a colonoscopy. Even with the 2 day prep where all I had was the prep liquid and pineapple jello, I didn't lose a pound! And everything came back normal. I am curious to see if getting of singulair will help this problem as well. As a side note, I have solved the constipation problem for the most part by taking Krill Oil. For some reason this just seem to help me go, and I discovered that by coincidence so I take one a day and I am feeling better in that area. As of 2 days ago I stopped taking singulair. I rather suffer with seasonal allergies than continue to swell up. I am now in an unhealthy overweight range and just feel disgusted with myself all of the time. I am CONSTANTLY watching what I eat, monitor my calorie intake and take in about 1200-1500 calories each day(I keep a food diary!). NOTHING works. In the past 2 days I have gone down 4 lbs already. This to me is not significant enough yet to say for sure, but I hope it's a sign of a trend to come. I cannot continue to put on weight. I am seeing others have had similar experiences on an older forum, but curious to hear the follow up. Have people stopped Singulair and lost the weight they put on?? Does it come off quickly? I am not sure how long singulair stays in the body and will continue to affect me. I am hoping not for long.


    SERIOUS side effects

    Hi, I have been taking Singulair for roughly 6 years. Yes, it helps with my asthma, but at a price. I've been suffering with peripheral neuropathy for a year. I didn't know what was causing it. I had many tests done but nothing seemed to be the culprit. One day I had the idea of looking up the side effects of Singulair online and realized that I had developed almost all of them within the last year: weight gain, rashes and other skin problems, sinus pain, neuropathy, mood swings, anxiety, and depression. I'm worried I've developed Churg's-Strauss syndrome but I need to visit my doctor before confirming it (the doctor that didn't even suspect this could possibly be the source of my problems). My point is: be careful! The longterm effects of this drug can be devastating! Allergies can develop further down the line. It's awful that we (asthma sufferers) have to make these decisions: breath more comfortably with the risk of suffering other horrible side effects, or suffer with asthma.


    Allergy to Singulair

    I have taken Singulair for about two years,Lately noticing that about 30 minutes after taking,I start to sneeze and sinuses produce copious clear thick mucus. I have allergies anyway,so wasn't quick to notice.Stopped taking it for the past two nights, then took it tonight and the symptons were and are worse than ever.I will drop it from my meds and let you all know the results. Thanks for this forum.


    how to wean off of singulair??

    my son is 4 and has been taking singulair since he was 2 and a half, after he had a round of croup, bronchitis and then developed a deep cough that came at night... he has not been specifically diagnosed with asthma, but i would like to take him off the singulair as i am not sure he even needs it. maybe the cough that originated the perscription would have cleared on it's own. he has not taken it for two nights and i don't see any reaction, but should i be weaning him off of it? he has had a rash on his arms since he started taking the singulair, and some behavioral changes. how do i get him off of it properly? has any one who has just stopped the medication had any problems? or has anyone been advised how to wean off? i had no idea it had a steroid in it, it says clearly that it is a non steroid medication. i get more upset as i read, he has had alot of the symptoms i see here, and i had no idea they were caused by singulair.


    nausea and stomach pain

    Our 3 year old son has been on Singulair for about a month. The past 2 weeks he has been complaining about stomach pain in the lower left side of his stomach and nausea. He thinks he is going to vomit about 12 times a day but hasn't yet and this is alway accompanied by stomach pain. Has anyone else experienced this? Plase help!!!!!!!!!!!!!!!


    Singulair, treatment for hives?

    I've had hives for over a year now and my doc wants to prescribe Singulair for this. I'm worried of the side effects. Please share with me.


    singulair

    im 15 years old and was diagnosed with "serious bronchial asthma wich causes heart spasms" well, they put me on singulair,advair, and nasacort. i took the advair awhile and it stated making me very irritable and bipolar-ish...so my mom told me not to take it anymore...but im also having a problem with hair loss...i mean im 15 years old...im not supposed to be loosing my hair...could this be due to the singulair?


    Singulair

    Hi my 3 year old daughter has been suffering from occasional cough but each cough "attack" would last more than a week. We went to our family physician who prescribed her with Singulair but said she is not asthmatic. This medication works wonders. She recovered within the next couple of days after starting on the medication. Recently, we went to another physician who shared that Singulair is a steriod which is not suitable for children who are not asthmatic. Now i'm very confused. Is singulair a steriod which is then not suitable for my 3 year old daughter who is not an asthmatic? But it seem that all other cough medication does not help relieve her once her cough attack starts.


    works good

    my 6 year old had chronic throat clearing and post nasal drip, the singulair has all but eliminated it. We have tried proton inhibitors, zyrtec and benadryl to no avail So far Singulair has worked well.


    Asthma & Allergies

    My 9 year old son takes Singulair to help with his asthma, along with Advair, Rhinocort and Zyrtec (he also has allergies). He started these meds in the beginning of 3rd grade, he had good grades (A's and B's) for the first quarter. Since then he's been struggling. He's in 4th grade now and is getting B's and C's. I'm not saying he's an A student, he's average, but does have the ability to do better. I often wonder if taking all of these medications has an effect on him. I was hoping to find something out or to see if someone else had this problem with a child. Thanks!


    No Subject

    My daughter is 3 and has been on singulair 4mg for 4 weeks, allthough her asthma cough has ceased and everyone is back to getting a good nights sleep, during the day she is very ratty and flighty, her appetite has increased and i see this as a side affect, minor at the moment but long term i think there seems to be worse.


    No Subject

    I would like to know if Singulair can cause hair loss.


    LBS

    I am a 60 year old runner. Since starting Singulair I have gained 10 LBS. I have increased my work outs till I am working out 4 hours a day. I have cut what I eat and still have gained the LBS. Makes me sick.!!!!


    Singulair for hives?

    My 9 year old son recently broke out in hives for no apparent reason. We took him to a doctor and he was persrcribed Zyrtec and Singulair. What I find odd is that hives are listed as a side effect of Singulair, and mentions nothing of treating them. Is it common to perscribe Singulair for chronic hives, and is it really neccasary when taking Zyrtec? My wife and I feel like the doctor perscribed it for monetary gain and not for his health.


    wieght gain

    I too have been gaining wieght but am unsure about if its due to starting singulair are if its from not being able to work out as much as i used to before my asthma came on.I have also been itching alot mostly the scalp? Is this commen.


    lasting side effects

    I was given singulair by my doctor three months ago . after about eight days i started noticing side effects os head aches , dizziness , extreme tiredness , felt like i had the flu . stopped the singulair , but the symtoms continue , and seem to be getting worse . i was given the singulair to treat allergies . my doctor says it can't be caused by the singulair because i don't have a rash . ? i never had any of these symtoms before using singulair. i'm 63 years old and was in good health except for the allergies . one thing that makes me suspicious is none of my allergy symtoms have returned , even though i stopped taking singlair over twelve weeks ago . i now have a fever , blurred vision , dizziness , head aches , muscle aches , and drowsiness. haven't been able to get any answers from merck . if anyone out there has any info that would be helpfull , please send it along . thanks , and good luck if you're taking singulair
