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)

 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

 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

 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

 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

 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'. M 3 5 weeks

 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. M 5 30 days

 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

 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. F 3.5 4 days

 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

 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 that 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

 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

 1  Allergies Son lost ability to concentrate. Screamed out nightly with night terrors. Normally an excellent student, but teacher called conference to discuss his lack of concentration. Doctor told me it was absolutely not the singulair, but when I took him off the medicine he was back to my normal child. Took son to allergist and he concurred that he had heard about these side effects with singulair. M 7 1 months

 1  Allergies & Asthma Easily angered, easily frustrated, horrible temper tantrums, PM restlessness, Bed wetting nightly, paranoid behavior, either loves something or more often HATES something - no middle ground ever Wow,for 2 yrs.I was convinced my son had beh.probs.He's the sweetest boy,very sensitive,but eas.angered.

Christian sch.& went from loving pre-k to fighting us on going.This year in K he was paranoid about kids not liking him & talking about him.We were very concern.'cause his teacher whom we love stated that this is completely untrue & that he plays well w/oth.kids.At home we felt we were walking on egg shells daily.He'd be fine 1 min.& then complet.hateful the next.I kept thinking maybe he's tired from not sleep well at PM & there are no naps in K. He would easily take a 3 hr.nap at home on the wknds., again not normal.

 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

 1  Asthma/allergy negative self-talk, suicidal vocabulary, aggressive behaviors, general negativity, listlessness, sleep hallucinations for 5 weeks after stopping drug - NORMAL KID NOW! Do NOT recommend this drug to other parents. 4 year olds that suddenly talk about killing themselves are influenced by a DRUG!! YOU know your kids!! Believe the parents who lost their children and learn from them. Doctors are not the all knowing when it comes to your child - YOU ARE! There are alternatives, find them!!! M 5 3 years

 2  Allergies Aggression, Anger, Defiance, Crying and Loss of Appetite My 4 year old has seasonal allergies and was given Singulair on top of his normal regiment of Zyrtec. From day one of taking the Singulair chewable tablet he became defiant, and uncontrollable. It has gotten much worse as we continue to give him each dose. I have stopped the medicine after 3 days and have already seen improvement. M 4 3 days

 1  Allergies Behavior problems, separation anxiety, school anxiety since kindergarden,anger,low school grades and her saying she wished she was never born/wishes she would die. 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
