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   Mood swings, anger issues, hyper behavior, not listening, excessive crying. My 6 year old started taking this to help with a cough he has as a result of chronic pneumonia. Within a couple of days we noticed extreme mood swings. Over the next week or so we watched our even keeled child lose his temper and cry. He wasn't listening and seemed to be bouncing off the walls. He was miserable, not worth the side effects. F 6 2 weeks

 1  Asthma I tried giving Singulair to my 7 year old daughter twice and both times she woke up in the night with severe hallucinations. She was screaming at the top of her lungs, as though she were tied to a railway track and a train was coming. She said that the bed was flipping around and that the blanket was flying all around the room. She was holding her ears and pointing at things in the room (that weren't there) and screaming "Mommy make it stop!!!!". Her heart was pounding out of her chest....it was just terrifying. From this experience and from what I've read, it seems very mind altering. It has only been around since 1998, so the long term effects are unknown. Very scary. I will never give it to my child again. Her brain is much too precious. F 7 3 days

 1  Allergies irrational behavior, ADHD like sypmtoms, anger, aggressiveness, night time fears, anxiety Our daughters symptoms GREATLY increased in severity after taking her off for a week and putting her back on Singulair. We were to the point of taking our previously "normal" child to a psychologist for testing. Our older daughter happened to catch the warning label which prompted us to take our 7yro off the drug. Her behavior has dramatically improved. The irrational behavior, anger, aggression, night time fears are now gone. She has had a very rough year in 2nd grade after having 2 excellent years in KG and 1st. We are absolutely thrilled to have made this connection. Thank you to all who have shared their stories. You made a huge difference for us as this was the first information I found and the stories were so remarkably similar it made a huge impact. Thank you!! F 7 13 months

 3  asthma aggressive, hyper With the winter thaw, my 5 year old son gets a terrible dry cough every year for about 2 months. I had him on steroid inhalers last year, but took him off after he become so aggressive he tried to choke me several times and he was still coughing quite a bit. I then tried Singular. He was not as aggressive, but very hyper on the 4mg I was prescribed to give him, but the coughing completely stopped. So I decide to experiment a bit. I HALFED THE PILLS and then HALFED them again so he was taking 1MG. Worked like a charm. Not as hyper and no aggression and it was just enough so that he didn't cough at night. My gut was that his little body couldn't handle the high dose and why not try and cut it down? Singular also has a red dye it in that some children have really bad reactions to. Perhaps that could be the problem as well. An alternative to that would be to be prescribed the adult dosage and cut it right down. Adult dosage does not have the red dye in it (the red for the 4 and 5mg is because it's a chewable for children). I think I'll try that next year and see if I can see a change. It's only for a couple months and I now give it to him RIGHT before bed so I don't have to see the instant change in him. Somehow my little dude falls asleep. Otherwise, he's running around like a banschee! M 5 2 days

 1  Chronic Congestion None My son has responded well to Singulair. He asks for it, himself, because it helps both his congestion and to clear his brain fog, which helps him focus in school. I am, very unfortunately, going to take him off of the drug after discovering it contains ASPARTAME. I have no choice, and I am gravely disappointed in this company for putting poison in a medication which is greatly needed by so many people. M 8 5 months

 5  For Asthma/Allergies Well it was for my 2 Year old son the very first dosage he recieved I noticed that he was very hyper it may not be from the singulair only because it was combined with zyrtec and the rescue inhaler as well. It was the first time I noticed he had those conditions a very bad cough so when bought to the doctor she placed him on those medications As a mother to other mothers as well as dads if your doctor prescribes this medication for your babies dont be too scheptical about using it. It worked for my baby and if your baby has the same conditions there is a possibility that it would work for your baby too. M 3 4 weeks

 2  allergy My 4 year old grandson was given this medicine for an allergy episode. On the 3rd night of taking it, he was having a problem staying asleep. He would begin to fall asleep and then wake me up to let me know "door closing" noises were waking him up. He also told me that he was having a bad dream that woke him up. He was not able to go to sleep for a long time because the "door closing" noises would not stop. He also complained of his leg being "asleep", but he had not done anything that would cause this to happen. His leg was numb for several hours. The next day, I double-checked on the side effects of this drug and was concerned enough to stop giving it to him. We've had no more "door closing" sounds or his leg being "asleep". His Dr. was not concerned at all. I believe this drug was causing my grandson to experience auditory hallucinations, nightmares, and numbness of the extremities. These are all possible side-effects from t M 4 3 days

 1  Allergies Extreme moodswings and anxiaty. Violent behavior and lashing out at the simplest of things. Very low self esteem and her grades went from straight As to Cs. Chronic stomach pain and headaches. Lack of appetite. Just turned into a completly different person. When I read about the side effects caused by this drug I almost cried. I never made the connection between the changes in my daughter and the medication. I just thought it was a part of her changing attitude as she got older. I will be immiediatly taking her off this medication and will hopefully see some changes soon! I so want my little girl back! I really wish the doctor had mentioned these possible side effects when he prescribed the meds to her! F 10 10 months

 1  Allergies and acute asthma MY daughter started taking this drug for her allergies.. it worked, her runny nose went away and she had a much easier time sleeping and breathing at night... after just a few days she hated wearing anything.. everything felt funny on her, she would pull on her clothes constantly.. her favorite shirt became her worst nightmare...she has always been the sweetest child and I can understand usual hate for clothes but something wasn't right.. she also started to get easily angered and would throw horrible tantrums and screaming and crying. she was not herself at all.. I thought she was going crazy until I figured out when all this behavior started.. she has been off it two days and I finally have my daughter back to normal.. Parents be aware of the serious side effects!! F 6 2 months

 5  Athsma symptoms None My son had two terrible winters - every cold he had resulted in a chronic cough that kept us all awake for days and became incredibly distressing for us all. Between colds was not much better with persistent nighttime cough that made him miserable from Oct-Mar. Summer he is a different boy with no issues. Prescribed inhalers made little difference. First cold of this winter was the worst yet and he coughed so hard for a weekend he was sick and crying from the pain. After I argued that the inhaler was having no effect the doctor prescribed this and his life has become normal. Colds like any other child but no persistent cough. We worried about his behavior over Christmas and after reading this forum reacted be withdrawing the medicine. This was a huge mistake and after a week we reinstated to eliminate the symptoms. The behavior changed were only with us and his childminder had noticed no difference. This medication has been life-changing this winter and any side effects we have firmly isolated as the terrible twos. M 2 2 months

 1  Asthma & constant resp infections Agression, screaming, tongue twitch, My gorgeous kind hearted little boy turned into a monster within a day of having this horrid drug. We were warned about possible side effects but that they were highly unlikely & I was so keen to just get him well I foolishly gave him the chewable medication. As of the next day he started screaming uncontrollably, hitting his siblings, throwing everything he could when couldn't get on way, throwing things at our dog, being completely defiant and totally out of character. In last two days keeps sticking his tongue out and twitching it constantly which he has never ever done before. Have probably only ever had to put him in time out a handful of times in past but this week he has spent nearly all of his days being sent to time out. He even bought me to tears today as he tried to hit me which has never happened before. Thank goodness i found this site. No more singulair for him and I feel so terrible for thinking the worst of him when now I KNOW it's the drug and not him that made him act like that, and feel worse still that I let him take it! A person can't change their personality overnight however that is exactly what happened when i gave my son singulair. DO NOT USE IT - M 3 5 days
