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  Astma My 5 year old went from a normal child to Mr. Hyde. Destroyed his classroom in violant episode. Attacked his teachers The drug did wonders for his asthma however over the course of 3 months he changed from normal to a monster. He was always a bit agressive but this took that agression and amplified it. Based on what I have read so far I am taking him off the drug and am hoping I get my son back. M 5 90 days

 1  Asthma My 5 year-old son took Singulair for about 6 months. He started Kindergarten around the same time as starting the Singulair. From being a happy, focussed little boy he became extremely violent, anti-social, un-cooperative towards his teachers. He would lock himself in the bathroom, urinate in the playground and draw violent pictures. His allergist recommended that he stop the medication immediately and it was like turning a switch, he went back to being his happy normal self again. My 12 year-old son has taken it for 7 years without incident however. M 5 6 months

 1  Asthma My son is extemely aggressive toward family members and his Mom. He jumps on her in bed and wrestles very violently with her. He is laughing the whole time, so it is not malicious; but he does act insane sometimes. He started with facial tics, eye rolling, and throat clearing a week ago, and I am very conerned that he may have these socially awkward habits later in life. After reading some of these postings, we are taking him off the Singulair today as we think that these tics may be due to this medicine. M 5 6 months

 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

 1  seasonal allergies/ asthma My 5 1/2 yr. old (for slight asthma/allergy) and my 3 1/2 yr. old (allergy/sinus problems) have been on this medication for only 4 days and they have both had severe personality changes: hyper, moody, don't listen, aggressive. NOT THEMSELVES! My 5 yr. old is being more strongly effected even though they're both on the same dosage. He's sad/happy/angry has started saying he hates himself, is hitting himself in the head...all out of nowhere! I SPECIFICALLY asked the MD if there were side effects to be concerned with..."oh no" he said,..."very safe". BULL! I figured I'd run a search on singulair side effects for my own peace of mind because I just couldn't believe their personalities could become so altered in just a few days for no reason at all! I found this web site...THANK YOU! My sons will no longer be taking this junk! God help all the families out there who are possibly having their children misdiagnosed with things like ADD/ADHD because of this terrible m I don't know if this stuff works or not...my 5 1/2 yr. old was put on it for preventative measures...he only uses an albuteral inhaler occasionally (seasonal allergy induced) and the dr. wanted to put him on singulair now to keep him inhaler free in the next few weeks as new allergens surface. My 3 1/2 yr. old was put on it for nasal congestion...he's still stuffy! M 5 4 days

 1  Seasonal allergies/Asthma BEWARE!!! Started giving this to my 5 year old son about 4 weeks ago...about 2 weeks into the Singulair, he became a different boy to me: Inappropriate social playing, mumbles that he hates himself or that he is a bad boy, cries over almost anything, wakes up in a foul mood as if he is hungover, and worst of all he developed a SUDDEN onset of "tics". These tics came out of nowhere, and could pass for Tourettes: shrugging his shoulders, always scrathing and tapping his nose and ears, wiping the back of his neck, rolling his eyes. Yesterday he got so bad he started doing all of them at once. We called our allergist, who said although it is rare to see, he had no other choice than to assume it was from the Singulair and advised us to take him off ASAP. KEEP YOUR PRECIOUS CHILDREN AWAY FROM THIS DRUG!!! WE HATED TO SEE OUR SON HAVE COUGHING FITS IN THE MIDDLE OF THE NIGHT FOLLOWED BY THE OCCASIONAL VOMITTING...BUT I'D RATHER HAVE HIM GO THROUGH THAT THEN PUT POISON IN HIS SYSTEM AND COMPLETELY ALTER HIS PERSONALITY TO THE POINT WHERE HE IS A SOCIAL OUTCAST AND COMPLETELY DEPRESSED!! I'D RATHER HAVE A CHILD WHO COUGHS THAN A CHILD WHO HATES HIMSELF, CRIES ALL THE TIMES, AND CANNOT GO TO THE PLAYGROUND BECAUSE HE IS WALKING AROUND WITH "VOLUNTARY" TOURETTES. IT IS ONE THING TO ACTUALLY HAVE TOURETTES AND HAVE TO LEARN TO LIVE WITH IT...BUT WHY WOULD WE INFLICT THIS ON OUR CHILDREN IF WE CAN HELP IT?????? M 5 4 weeks

 1  Son was for Allergy Induced Asthma Our son became irritable and gained 10 pounds! He had nightmares and threw temper tantrums. It did help his Asthma, but our sweet, loving boy became violent and out of control. The doctor acted like he had never heard of these side effects but they are even on the Singulair website in the post trial side effects section. He is now on Claritan Ready Tabs and his nasal spray...here's praying... Not worth it at all! M 5 6 months

 1  asthma mood swings, dpression, anxiety, fears, fatigue, listlessness at times my now 5 year old son was prescribed this drug over 2 years ago. we recently have had issue with some very disturbing thoughts he has verbalized ot us--on the order of everyone dying and him being happy with that...anyway-because i was so concerned about it, i went to this site and found, to my surprise, that so many others have found all of these same side effects with the drug in children. to the folks who state that it SHOULDN"T be given to children--do your homework before you ridicule others--it IS indicated for children according to the FDA and the AMA--how we know NOT to give it to our kids? what i can't imagine, is why the FDA hasn't pulled this drug. i see this causing SEVERE problems in our youth and i have taken my son off the drug as of this evening. please do the same for your child if they are on it.

 1  Allergies and Asthma Aggressive behavior, temper tantrums, nervousness, anxiety, depression, hair loss, hyper,moody,unusually tired in the mornings. My now five year old son was prescribed this medication when he turned two. Approximately 6 months after taking it, his entire demeanor changed. He turned into a very moody, angry, sad child and started losing his hair. The pediatrician, allergist, immunologist,dermatologist, and specialists all said that it could not be the medication causing his hair loss. He now has no hair at all. Recently, I have found links to Singulair and hair loss and I am ANGRY. My child has been treated for Alopecia for now 18 months and this terrible drug could be the cause. As soon as I found the connections to his behavior changes and hair loss I took him off the medication. It has been three days now, and I have already noticed a modification in his agressive behavior. Parents should be aware of the harmful affects of this medication. M 5 2.5 years

 1  chronic sinusitis My son began taking singular the week he started Kindergarden. After about three weeks on the medication, he began having night terrors, itchy skin, aggressive and impulsive behavior in school, and became easily fustrated/aggitated with simple tasks. We began to wonder if he had ADHD or some other type of behavioral disorder. I then google singular and found this web site. THANK GOD FOR THIS WEB SITE!!!!!!!! We immediately took my son off of singular and within 4 days we saw positive changes in his behaviors. These side effects were completely gone in about 3 weeks. He is doing great in school and has not even had one sinus infection. PARENTS, DO NOT GIVE YOUR CHILDREN THIS DRUG!!!! M 5 3 months

 1  asthma, fluid in ears, wheezing paranoia, anger, tantrums, hatred, aggression, poor appetite my 5yo son was prescribed this about 2 wks ago. He has become afraid to go anywhere in the house alone..in broad daylight. He is throwing fits at night about not wanting to go to bed, he has been screaming 'i hate you' to his father and I, throwing things, upset about everything, cannot just sit to focus on simple tasks (eating, chores,etc). My older son had had a similar reaction to lg dose of dexamethasone (steroid) for croup when about 2yo so that made me look into this new med my youngest started. We are stopping it today.

 1  asthma and allergies mood changes, extreme irritability, difficulty focusing, anxiousness, severe crying bouts, depression, low self-esteem, vivid and terrifying dreams, stomach pains, muscle pains, etc. Our sweet little girl began taking Singulair 7 to 9 months ago to help manage her asthma and allergies. Initially, it seemed to do the trick. She's gone over a year w/o a hospital admission. However, we also noticed that she began "acting out" a lot and she just didn't seem herself. She began having much difficulty in school since she could not concentrate. She began crying in school everyday out of frustration as well as at home. Where did our happy little girl go? She is on several meds for her conditions and we never stopped to think it could be Singulair that would cause these side effects. However, over the last few months she has had increased trouble with sleeping and waking nightly with vivid terrifying dreams. We've also been told that she needs to repeat kindgergarden due to her difficulties in school. The benefits DO NOT outweigh he risks. We've chosen to help our precious little girl find her happy self again. We've missed her! Please, think twice abo F 5 7 months

 1  Allergies & Asthma Cranky, Hair loss My normally sweet little girl was 4 at the time she was taking Singular for her allergies and asthma. SHe was normally very sweet and cuddly. Just aster a couple weeks she became mean and very cranky. Then one night I was giving her a bath and washing her hair, and I har a handful of her hair in my hand.I freaked out I called the doctor and the pharmacy and no one knew what was going on. SO I did a bit of research on Singular. It has been known to cause hair loss. I was horrified. She had very thick curly hair. She lost about half of her hair. SHe has been off this for about 5 almost 6 months now, her hair has stopped falling out and is now growing back. It worked for her allergies and asthma, but the hair loss was just too much for her to go through. SHe now takes Qvar and Claritin for her asthma and allergies. F 5 3.5 weeks

 1  Allergies Extremely hyper, impulsive, and defiant My son took singulair for 6 weeks for his allergies. We noticed that he was acting so bold - not listening, crying and randomly screaming for no reason. He was became very nervous and started biting his nails. He literally could not stay put or on track. He cried about everything. He was prescribed this by his primary care physician, who never told us of these side effects. We went to his allergist who immediately switched him off this. Today his teacher commented about his "hyperactivity" and I wanted to cry. He has been off it for a week and is just starting to return to normal. M 5 6 weeks
