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)

 2  asthma/allergies agressiveness, tantrums, crying, yelling out, anger, mood swings, not listening, unable to focus, 360 change in personality. My 4 year old son took singulair on 2 occasions for about a month each time. It did seemed to help his allergies, but at the same time his personality changed drastically. At first I thought he was going through a phase. He became a different child. very difficult to deal with. I feel so guilty about getting angry at him for his behavior while on this drug. I finally made the correlation and took him off of it. After the drug got out of his system, he was back to his usual sweet self (both times). I hate the fact that I was punishing my child for his behavior when it was my fault for giving him this poison. Be careful giving this to your child and watch out for the side effects. It may work for some, but it seems like it has a bad effect on others. It is sad with the kids because they can't communicate how they feel like and adult can. What good is a medication if it makes you unable to function. M 4 2 months

 1  allergies insomnia, fits of crying, seperation anxiety, irritability I take this medication myself and it has been a miricle drug for my lifelong asthma and allergies. However I noticed side effects in myself of depression and fatigue. I have tried to give it to my son two different times as prescribed by the ENT doc. Each of the intervals I've tried it he gets the listed side effects. I just got very angry because my son will not stay asleep. It is absolutley awful and has really alerted me that my seasonal depression could be intensified by this drug. If it affects him so dramatically then it could be the reason I have been so depressed for years. I went on the computer for support. I will not be giving him singulair EVER again. I'm going to go hold my little boy now. I feel so bad that I tried to give him this drug again. Doctors are really blind as to the side effects of this drug. It is not such a miracle drug to me now.

 1  seasonal allergies My second grade son began crying at school and started having seperation anxiety. He began crying at the bus stop in the morning and not wanting to leave us. This was very unlike him, so this site we found made us wonder. His doctor agreed to have him stop Singulair to see if that was the culprit. We are very happy to say within three days off of the Singulair, he is having no more issues with the separation anxiety and no longer crying at school. His allergy syptoms went away, however the singulair was in conjuction with an antibiotic so unsure which cleared the heavy cough. M 8 3 weeks

 1  allergy induced asthma/sinusitis intense, unexplained depression; rages. My daughter was put on this from 4-5.5 yrs with significant behavior changes resulting in many sessions on willful children and behavior modification. We did not like our own child and were concerned about a total lack of empathy for others. We attributed her dramatic improvement to a sweet, even tempered child to entering kindergarten. In hindsight, the improvement actually began when we discontinued singulair during the summer. We put her back on singulair when she was 8 and noticed a return to the same out of control, raging behavior. She sat in her room and sobbed uncontrollably, scaring us and herself because she had no reason for feeling so incredibly sad. After 2 weeks we discontinued and noticed an immediate return to normal within 48 hours. I am so angry that every doctor we saw denied that this drug caused any side effects!! The drug was said to be "benign" and absolutely "free of emotional lability issues." This should be given with specific pre-warnings and advice for careful observation. It is a useful drug for severe, uncontrolled asthmatics, but has no place in a physicians list of approved meds for average sinusitis, allergies, or managed asthma in children of any age. Drug of last resort. The FDA and Merck are seriously hiding facts that parents on this board are seeing and reporting. Direct cause and effect. Since my observation of my own child I have shared this info with other parents locally and have personaly s F 10 2.5 years

 1  allergies Irritability, hallucinations, depression It also did not work for my daughter's allergy symptoms. I feel so bad for giving this to her. Every day her mood has gotten a little worse, and she just feels like every thing bad happens to her. She woke us up in the middle of the night screaming b/c she thought there was a man in her room.

 1  allergies This was given to my almost four year old daughter, she became very aggresive, crying over evrything, very moody, angry, clingy, loss of appitite, just completely changed her. I looked up this med years ago when the doc wanted to give this to my daughter, I saw whet it did to other children so I told the doc no, years later she still has her allergies she has been plaged with them since about 10month old and has had five sets of tubes for her ears and her atinoids out twice. Her father took her to the ENT do to the coughing coming back and she said her ears itched again which normaly happen when a tube falls out and the ear fills with fluid again, but the doc said it looked fine but said she seemed to have allergies still causeing the cough he said to put her in Singular, after a couple of days I noticed her mood change, at first we thought it was do to number one the age and number two the divorce, but when she started crying over everything we thought she might be getting sick. I was at my neighbors and I said I bet this is the one med I did not want her on, as soon as I pulled up the site I know this is the med that makes kids wig out we threw the perscription right away, now I need to call the doc to see how long it takes to get out of her system. Please do not put your kids though this they do not understand and I feel bad for them having to go though the moodswings of this med. F 4 11 days

 4  Allergies Asthma Wow. This has been an eye opener. I came to this site for another medication, but I think I've finally put this together. My 3 1/2 year old has been very aggressive. In fact, got in trouble today at sunday school for starting a fight with a child. He has also been hyper, unusually loud, and has screaming fits. However, a few weeks ago we traveled home to Chicago. We were out of our routine, and I kept forgetting to give him his daily dose of singulair. I noticed that my child was so well mannered, calm, and tried to assist his younger cousin whenever she would have an emotional meltdown. I thought, wow, he's growing up and maturing. Not so. When I returned home, we returned to our usual one dose in the morning of singulair, and he was back to his very difficult self -- constnatly wanting my attention, getting upset at the drop of a hat, difficult sleeping. I think I may have found the culprit. I'm going to keep him off for a week and see if there's a noticeable difference. The med works for keeping his allergies and asthma at bay, but the emotional side effects are far too demanding on a child -- if not the entire household. M 3.5 4 months

 4  Allergies/ asthma My 7 year old son was able to breathe and not have to use his inhaler as much which was wonderful, but his behavior suffered. He had mood swings, very irritable and aggressive. After going to this website and on-line I am going to discontinue singular and try another drug to help him. It there were no side effects with behavior he would still be taking it because it is the best medicine that we have found so far to help with his allergies and asthma. M 7 45 days

 1  Seasonal Allergies Severe Depression and Agression My son was on this medication for six months before I finally made the connection between the drug and his behavior change. He became very depressed, nearly suicidal, often telling us that he wished he had never been born, wanted us to kill him, and that he didn't want to live anymore. He was also very aggressive toward his younger siblings. All of these behaviors were way out of character for him--typically a very compassionate and joyful individual. Within two weeks of being off the drug we had our normal, happy, loving boy back. NEVER EVER, EVER give this drug to a child. When I related our experience to the allergist he was not surprised, has seen it before (argh!) and said that my son can't take Singulair, Zyrtec (He had similar results with Zyrtec), or Claritin. Be very cautious of drugs, parents! M 7 6 months

 1  Asthma Complete personality change in a little over two week period. DO NOT GIVE THIS DRUG TO CHILDREN. This drug came highly recommended by our allergist. He insisted we take the drug to help with modest asthma. In the period of two weeks, our good natured well behaved child turned into a nightmare: fighting, punching, overly emotional, reclusive, mood swings, anger, etc. We took him off and the problems went away.

 3  asthma The Dr. put my daughter on this medication at age 2 after my daughter had respiratory failure due to reactive lung disease. I thought that it was a godsend as her breathing much improved and she was able to participate in simple activities like running after being on it for a month or so. At about age 4 she started having headaches, sore throats, neck pain, leg pain, stomach aches and nightmares. I have had her in the doctors office several times over the last year for these symptoms and never got any answers or indications that the singulair might be causing these symptoms. I am furious! My sweet four year old has headaches all of the time and not one of the doctors mentioned that this could be a side effect! F 4

 1  asthma/allergies Severe stomach aches, headaches, bloody nose, mood swings, loss of appitite My 8 yr old son has been taking this horrible medication for approx. 4 wks and when he started complaining of the stomach ache and headaches I told him he was over reacting, I feel so guilty for not listening to him. Why don't our Dr.'s tell us about these side affects. M 8 4 weeks

 1  allergies/asthma Headaches, severe stomach ache, bloody nose, agressive, emotional, mood swings My 8 year old son has been on this for aprox. 5 weeks, and I now feel so guilty for accusing him of over acting and just wanting attention! This is horrible medication and I can't believe our Dr.'s don't give us these warnings. M 8 5 weeks

 5  asthma none It has been a godsend for us to have my 9 yr old daughter's asthma controlled. No more middle of night trips to ER and endless oral steroids/inhalors. Fortunately no adverse reaction of any kind. It would be very unfortunate for us to have this med unavailable. F 9 4 months

 1  seasonal allergies My son was on and off Singular for several years for his seasonal allergies. We finally realized that he has always been a very strong willed child, but whenever he was taking Sin gular he became very aggressive. We refused to put him on this medication again. It did help his allergies, but was not worth the side effects! When I told our pediatrician he was not aware of this side effect. He went and checked his medicine book and found that increased aggressiveness WAS a side effect. Would not give to children M 7 2 years

 1  Asthma excessive crying,mood swings,depression,highly emotional,trouble focusing/listening Finally answers to all of my questions!!!!!! It's been about 5 years that my 6 yr old son has been on singulair. Ever since he's been on it I've had problems with his behavior. Sure the doctor was right about the attacks being controlled but not his behavior. It's a blessing to have found this site. My son will no longer be taking this medication! Singulair should be recalled due to all of these side effects it has caused in children and adults. M 6 5 years

 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!

 3  Asthma Mood Swings, Headaches, Hyperactivity, Loss of Appetite GREAT at controlling asthma symptoms, but my sweet-as-pie 5 year old began screaming and crying at the drop of a hat, telling me she hates me (then crying about it 2 minutes later), throwing tantrums, became more hyper than usual, and complained of headaches very frequently. She also lost a lot of interest in food. I had read about the psychological side effects in a magazine, but against my better judgment, her father put her on it anyway. Needless to say, I dont give it to her when shes with me, and after reading all this info I wil be encouraging him to stop it altogether. F 5 2 months

 3  Allergies My 11 year old son was prescribed Singulair for seasonal allergies. The medication worked very well and we were happy with it, until my son started waking with violent and disturbing night terrors. He was trembling and drenched with sweat everynight. M 11 6 weeks
