singulair behavior problems

There is a Facebook page about Singulair side effects. It is a lot of parents supporting each other from all over the world. It is called Making the side effects of singulair aware to parents of children & teens 

Hello everyone my name is Jason Roussel I am 23 years old and been an asthmatic since I was 2. Through out my years my doctors have changed my medication many times. For the past 10 years I have been using sigulair. I am currently on advair twice a day and sigulair at night. Mentally, I try to stay away from sigulair because I dislike taken pills etc. So I would medicate when my allergies act up. (When I was younger I followed my doctors rules I just started doing this this year.) (Advair is much more of a daily routine with out that I wouldn't be here typing this) . I am here typing this because I think I finally put a thumb on what makes me go "nuts". I can be honest and say I have a temper problem but it becomes much more than that in negitive situations. I explode, go bizerk, Anger so strong I feel it's neasecary to persue. I do have a grandma who has metal issues and takes medication everyday for it (resperdol) as well as a cousin who never fully mentally recovered from drugs. But I am a determined and focused Young man and after yeaterdays last explosion and how I feel at this very moment is so confusing to me because of the way I felt yesterday. Singulair is said to be taken before bed time, Which I had taken it the day before yesterday at night and this is how it began. I was on edge yesterday all day mad, angry focused mostly on negitivety. Went on a social media web site and all the people making fun of others I tried to hurt their feelings to stand up for them. Yes it's the right thing to do to stand up for others but who am I to hurt anyone's feelings. Secondly and most importantly exploded on my mother. Before she left for church, she handed me the phone bill and said read it. I WENT NUTS. It gradually built up to me waiting for my moms to get home to argue with her. Which I did. We argue alot I am angry alot which Is why I never thought anything wrong with it because I can't see anything different. And my mother takes it all. Lastly I met up with a bunch of friends who are home for the holidays which we have been going to the gym and staying healthily more than usual. (I eat healthly also) This has helped me to maintain a clear mind which is why I am able to compare how my thoughts are now and how my thoughts were yesterday.Tthe entire time I was angry and positive at the same time. I was uncertain of how I felt and confused because I haven't seen some of them in a while. I have been emotional writing this because of the truth behind it but, today I am o.k. Back to a much clearer mind with hope and desire. I am not going to take my singular anymore and going to go apologize to my mother for the past 10 years, especially yesterday.

I join in the last post in saying that I took Singulair for exercise induced asthma for over 8 years, at first on a 5mg dose and then increased it to 10mg. (I am in my 30's).  While I can think of issues I had the first few years-it has been that last 4 that I had significant changes in my anger as well.  I would get super mad at the smallest thing, almost a rage at times that would come from no where over stupid things.  I had several stressors in my life at the time that I thought were to blame but would often come to tears after I got mad saying this wasn't me and what is wrong with me.  I some how missed the first reports about this association with the drug and the mood chanages.  So I noticed the warning on the bottle, looked up the reports and cried thinking I had taken this drug for so long and thought I was going crazy.  I immediately stopped the drug (my asthma isn't that bad and I had inhalers just in case) and made a dr. appointment.  4 weeks later, I feel back to my old self, have had no rage or flashes of anger since about 2 days after I stopped the med.  I know some don't have these effects but I did.   

My 7 year old son was given on Friday for his asthma that is mostly drainage and coughing. After two days being on the singulair, we were preparing for bedtime at 8 p.m., and he begins jumping in the bed trying to do flips, rocking back and forth hugging a pillow, starts hitting everything with the pillow, hits me multiple times, hits the dog, and he tells me that he can't control himself. He tells me that he feels like he can jump for two days and he said he felt very hyper.  I knew our son was having a very horrible reactions to the singulair, because I have never seen him behave like this before. I take him to ER. On the way there he is hitting the dashboard constantly, then once we have him in the hospital, he is hitting the bed, telling us he wants to hit everyone. I called the pedi this morning and told the nurse that I took him off immediately and throwing it in the trash. I was angry they didn't tell me what could result from Singulair. I will try local honey, and continue him on Benedryl, because I don't believe Zyrtec is helping with the bad drainage from allergies.

My 2 yr old son has been on it for over a year and I have noticed especially in the last 6 months his behavior and aggression and tantrums have become like you said just unruly ... I am taking him off the singulair today because like you I know my child and I don't think he's "just bad" ... I hope to see a difference in my baby boy soon

Singulair almost cost me my daughters life. She is 14 years old and has been on singulair for almost 2 years.

She is a straight a student, very well behaved, social and outgoing child.

Shortly after starting the medication she would come home straight from school and go to sleep. This was not normal.

She is a multi sport athlete, softball, basketball and volleyball. I figured we must be pushing her to hard with year around softball. I took her out to give her a break, thinking this would help. It did not.

This became the norm up until the day after Christmas 2017. She started having panic attacks and sucidal thoughts.

Immediately I started trouble shooting issues. researched singulair and she had every "call your doctor immediately side effect"

I called a doctor friend of mine and asked him if I could take her off without weaning. He said sure but that don't cause these issues. I told him do some research.

Took her off medication. After day on headache, burning head and flush face was gone.

Still was having panic attacks and suicidal thoughts. Ever day has been progression. All physical symptoms have vanished, panic attacks have vanished and suicidal thought have greatly deminished.

We are not all clear yet, but a week after stopping, it's gotten much better.

She is finally out of bed and in good spirits, which we have not seen in years. My baby is getting closer to whom she used to be pre singular.

Wow. I honestly felt like I had written this while I was reading it. My son is doing the exact same things and has been on singulair for a year now.
His problems have been going on for several months now and are only
getting worse. Thank you for your testimony. I have been wondering what I have been doing wrong as a parent. I will be calling his doctor.

The same thing happened to my daughter. How do we report these adverse reactions?

Good to know you moderate the use.
