SINGULAIR  (MONTELUKAST SODIUM):  Montelukast is used regularly to prevent the wheezing and shortness of breath caused by asthma and decrease the number of asthma attacks. Montelukast is also used before exercise to prevent breathing problems during exercise (bronchospasm). This medication can help decrease the number of times you need to use your rescue inhaler. This medication is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose). This medication does not work right away and should not be used to treat sudden asthma attacks or other breathing problems. This drug works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies. It helps make breathing easier by reducing swelling (inflammation) in the airways.   FDA Approval Date: 1998-02-20 (Sources: U.S. Centers for Medicare Services, FDA)

 1  Chronic Rhinitis, Asthma Anxiety, depression, loss of control, leg pain, etc. I had no idea when we started our daughter on this drug several years ago that it had the impact that it did. My daughter has had many lung/nasal issues her whole life and started Singulair in combo with other drugs when she was about 3. When she was 5 her teacher mentioned that she seemed to "zone out" often. In 1st grade her anxiety ramped up and she was caught poking herself in the arm with a pencil. This is when we started her in counseling. We stopped Singulair in the summer between 1st and 2nd grade because we thought she didn't need it anymore. She flourished in 2nd grade and we thought it was due to the counseling. This spring we started her back on Singulair for her nasal issues and by the end of the summer we noticed that her behavior had regressed. She was anxious, kept saying that her brain was telling her what to do, several OCD-like actions that she couldn't stop, she felt "weird", unable to cope with small annoyances. Her counselor and I were perplexed. At a recent appt with doc for refill of Singulair she mentioned the side effects. I was appalled! It all started to make sense. We stopped the drug that night and she has been slowly improving. The major impact has been on her anxiety. She is so much calmer and happier. This drug is EVIL!! F 8 5 years

 2  exercise induced asthma anxiety, panic attacks, nightmares My 7 year old was prescribed Singulair during soccer season in fall. His environmental allergies and running cause asthmatic symptoms. After just a few days, he was like normal. He could run and be outdoors with all of his normal triggers with no reaction. This medicine does work, no doubt. But after about 3 weeks on the medicine, he confided that he had been feeling wierd at least once a day and couldn't make it stop. Upon further questioning, I realized he was experiencing panic attacks. He described that he felt like things were happening that weren't really happening, so I believe he was also hallucinating, or this could have been part of the panic attack symptoms. Lastly, he mentioned that he had some horrible nightmares about monsters recently. Knowing there are some serious psychological side-effects, we stopped the medication and anxiety and nightmares never occured again. If you do put your child on this, I would suggest asking them daily if they are feeling ok, as they may not realize things they are experiencing are abnormal or they may be embarrased to talk about it.

 1  Constant runny nose & cough moodiness, irratability, crying, sad. My extremely happy 6 year old daughter started takeing Singulair 20 days ago....within approx 3-4 days I started noticing slight changes in her personality. Figuring everybody has a bad day I didn't think anything of it but they became more often and more out of charachter. I started putting 2+2 together and kept coming back to when she started taking Singular. We just got back from the pediatrician and come to find out....I'm not losing my mind, nor is my daughter. He said to stop "cold turkey" and that he had had other patients who had similar experiances....like 1 in 20. The benifits of less of a runny nose were not worth it. I thank God that I caught on to what was causing the issues and I can't wait to get "my" daughter back. DO NOT LET YOUR CHILD TAKE SINGULAIR!! F 6 20 days

 1  asthma like symptoms My twin boys were 18 months when they took this medicine and they BOTH began to have mood swings, one alot more than the other. We noticed it begin 2 days after we started the medicine and within 2 weeks our one son was having major fits 4-5 times a day for about 15 minutes each. You could tell he was unable to control them. It worked great for there cough at night and wheezing but the behavior change was not worth it. After we stopped the med we have not seen those behaviors. M 2 3 weeks

 3  Asthmatic Symptoms My son is 2y 11m and was prescribed Singulair for Asthmatic symptoms after 3 months of continuous illness ~Within 5 days his breathing improved dramatically and i was impressed with the results, however after 10 days his skin on his arms and legs became like sand paper and then he became hyperactive at night He is a fantastic sleeper having gone through the night from 4 months He wakes in the night banging the cot, screaming and wanting to run around, which can last for hours He seems unable to hear me and falls asleep exhausted only to sit bolt upright again minutes later I hardly recognise him Usually a passive child he bites, pinches and kicks He has Downs Syndrome and many medical problems for which he has other medication so i dont know if this is only the Singulair or a combination problem Once i read the side-effects leaflet i felt sure this drug was a cause He sees the Pead in a week so i have halved the dose until then....

 4  Asthma My daughter has been on the medication to treat her asthma for quite some time. I never thought much about the side effects because most drugs come with side effects and you can't get too hung up on every detail, especially when the benefit of taking the pill is clearly positive. In the past several years, I have noticed my daughter's propensity to anger very quickly and when she does, it is completely out of control. She unleashes on me and her brother, in particular, and she has told me that her brain just can't control it. I started wondering about why this was so prevalent with her and whether there is a connection between her taking Singulair and this behavior. Also, for the past several years, she has a facial tic that comes and goes. While this is not uncommon in children, she seems to get it every year around the same time -- when the weather starts to get cold. I am now starting to wonder if there is a connection between her Singulair intake and her facial tics. Based on F 8 5 years

 1  allergy symptoms - cough/congestion Temper tantrums, crying over smallest things, agressive, pushing, bad dreams, potty accidents, generally out of sorts My 3 yr old son was prescribed this medication in lieu of Zyrtec while awaiting allergy testing. We go to the doctor tomorrow for the tests. I stopped giving him Singulair today. I have seen a DRAMATIC change in his mood. He is aggressive towards me and his sisters and father. He does not want to participate in even the mundane activities of the day like taking his sister to school... throwing himself on the ground, crying, hitting. He never did this before. He has also had 4 pee accidents in two days. This is a first. He has not had an accident since he was potty trained 6 months ago. No other changes have taken place in our family, no other trauma I can point to. He suddenly just felt "bad". He doesn't know why when you ask him. I had some reservations before going on the medicine when I read the indications on the package. I asked his current Pediatrician and his former Ped. and both felt it as safe as their children were on it. This is just too coincidental for it to be a behavioral problem that showed up out of the blue two days after starting this medication. Thank you for the posts. It just confirmed "that little voice inside" that said something was wrong with this medicine. M 3 5 days

 1  Asthma My daughter, now 6, has been on singulair since she was like a year old. She has always seemed sad and worried about everything and at times had the "glazed over look". Her father and I divorced when she was very young and it was not the nicest divorce. We always chalked up her "issues" with the divorce and spent lots of money on therapists who couldn't find anything wrong or abnormal. Recently, we uped her dosage due to her age and her asthma still not being under control. She startd having some even crazier behavior problems! She was more angry and at times, out of control. She was anxious all the time to the point the school called to talk about it. She seemed more sad than usual and sometimes out of it! She complained of a tummy ache all the time. She was just a different kid, worse than what we had grown "accustomed to". I heard a story on TV about Singulair and the side effects. I started doing research on it and immediately called the specialist who M 6 5 years

 1  asthma anger,nightmares,uncontollable crying, itching, pains in parts of his body, eye rolling, depressed and anxiety. My 7 year old son was put on this for allergies to help his asthma and it did that. But we started noticing behavior changes and he became a totally different child. It finally clicked when he woke up and his eyes were rolling constantly all day. I went on Singulairs website and noticed he had every side effect they had listed. We quit giving him the Singulair immediately. It's been 7 days today and he is slowly improving. His eye rolling is only once in a while or when he gets tired. Today was also the first time he didn't have a nightmare. I feel awful for not checking Singulair out before putting him on it. Thank you to everyone who has put something on here. It has been so helpful to read about all your experiences. M 7 6 weeks

 2  Allergies, possible asthma Wow! I am so glad to have found this site! I came on here to see if there were any negative effects to stopping singular, as they warn you on the label. My son started this at 3 and we've had a miserable year and a half! He became aggressive toward others, unable to control himself, and a complete nightmare. At his 4 year check up they recommended seeing an OT for sensory processing disorder. We have eliminated all processed foods, sugary drinks etc....well, I have not refilled his prescription in the last month and he has been an absolute angel. Honestly, he is a new child and we are all solo happy! I can't believe it has taken me so long to figure this out. M 4 1.5 years

 3  asthma sleepwalking, night terrors, bedwetting and in the last 6months leg pain, stomach aches. My daughter started taking this when she was 3 and is now 7. She was recently diagnosed with auditory processing disorder, dyslexia and ADHD. My husband found this website and we are going to take her off singular and see if it makes a change. Her sleepwalking is so bad we have an alarm on the house as she has tried to get out a couple times. Very scary! I will update post and let you know how things are going. Thank you all for posting.

 1  Reactive Airway Disease Huge facial tics, anxiety, mood swings, uncontrollable crying My 7 year old daughter has taken Singulair regularly for 6 months, but her behavior over the past 2 days has been so bizarre I was compelled to do a Google search and came across this website. Last night was a complete meltdown over every single thing that could have possibly been a minor annoyance, such as not being able to squeeze enough toothpaste out of the tube, which culminated in a 30-minute screaming and crying bonanza. She said to me last night that she is "just not happy" and that she doesn't know why. I was reading stories to her tonight, and she must have popped her jaw open at least 40 times over the course of two books (mouth open wide like a yawn in fast-forward). I was keeping an eye on her, and a few times I asked her why she kept doing that and she said she didn't know, and she thought maybe her mouth was "itchy" - I said "baby, that's just not normal behavior" and she said "I KNOW!!! But I can't stop, mommy!" The moodiness and crying have become progressively worse over the past few months, but the facial tic for the past month is the final straw for me and confirms my suspicions about the other behavior - I stopped giving Singulair to her today. UPDATE 12/06/2010: The facial tic that my daughter had for about one month disappeared three days after discontinuation of Singulair, and her anxiety and other mood disorders slowly faded away shortly thereafter. Her chronic cough has reappeared, but I am managing those fairly successfully with Vitamin D and Omega-3 capsules F 7 6 months

 1  cough-variant asthma My son (almost 6) was on Singulair from the time he was 2 until a year ago when I took him off due to his EXTREME behavior. He was rude and defiant at home, but at first we chocked it up to the "terrible twos". Once he began attending daycare(2 years old), though, his behavior got WORSE. He would hit and push the other children, outright defy the staff, and would NOT follow directions/rules, no matter WHAT the consequences were(time out, mom called, etc). Last year he started attending Pre-K and the behavior continued, but the staff was NOT going to take it(they didn't have to, private school). he would NOT sit still, would not finish work, and the violent behavior continued. Since it really wasn't helping his asthma, since it isn't allergy-related, we chose to take him off it and see what happened. Well, it took a couple of weeks, but he's now like a DIFFERENT child! My son now(1 year later), is exceeding most, if not all expectations at school(kindergarten), well behaved at home, and actually will sit and read books with an adult and not be racing around the room. Even his pre-K teacher, who we went back to visit, could NOT believe he's the same child! I am SO glad we took him off it, we will NEVER go back. I was interviewed by a Fox tv station in DC for this topic and can't wait to see what(if anything) comes from it. M 5.5 2 years

 2  no Irrational anger, agression, hitting, crying, kicking, nasty, screaming, waking in night and they would tell me they didn't know why know why they were feeling this way. I thought I was a bad mom till I started researching this drug. Ther is a Natural Alternative called RESPITROL. Initially like most natural remedies it takes time to work but it does work AND there are no more irrational behavioral outburst. My kids were telling me they were bad kids when on that horrible drug. Now they tell me they feel really good like they never did before. Can you imagine how many parents think they are bad parents and other kids feel they are horrible kids? Spread the word and ask your doctors to help you use this product. If they won't, find one who will. We have to stop drugging our kids. There are so many great alternatives out there. Most drugs cause negative side effects, and aren't even tested for kids! They are unnecessary as I am also finding out... for example, most kids are deficient in Vitamin D which will prevent flu and colds. Diet is also important. BEAWARE: aspartame is in singulair which itself has many negative side effects like depression, irritability, anxiety and personality changes [it in a lot of your processed foods]. Educate yourselves! M 6 2 years

 3  preasthmatic syptoms Our daughter began taking Singulair at the age of 3.For two years, we had problems with agression, biting herself, refusal to listen, no remorse for hurting others. It was a nightmare. The meetings with teachers and their attitudes were not helpful. We left 2 preschool settings. Potty teaching also was a problem, and we are still completeing training. I was relieved to find this site. We took her off Singulair. We saw immediate improvement in her behavior, mood, cooperativeness, etc. I am sickened that it took us so long to see the negative effects of this drug. While it was helpful, and it helps a number of kids, I would initiate taking Singulair with great caution starting on a weekend and watching carefully for any changes in behavior, mood, etc. Our 5 year old is better now, but has lots of catching up to do because she was so unfocused during so much social training. She is now on allegra and seeing an allergist for her symptoms. I regret the precious time that she was so unhappy F 5 2 years

 1  allergies Emotional problems - anger, crying, etc. Have been through all of this for a year, including using zyrtec initially, then trying different prescription meds which all caused severe mood swings and extreme stress in general on our family. The best thing I've found is QBC (Quercetin, Bromelain, and Viramin C Complex) at our local herbal shop. Stops the coughing and has no side effects. We also use natural cough suppressents like Sinupret syrup, which is all natural, including the cherry flavoring. Also, using the Neti pot seems to help as well along with putting vicks on the soles of his feet and wearing socks over them when he sleeps at night. M 11 15 days
