Xoponex symptoms and conditions

My son is 3 and has been on Singulair since around springtime (I think... I've lost count). Anyway, during this summer we noticed his behavior had just gone straight to hell. At first I was attributing it to the wonderful world of the three year old, but it was just getting ridiculous. He was having countless meltdowns, screaming bloody murder (I mean SCREAMING to the point of going hoarse), hitting, punching, slamming, banging, crying hysterically for ridiculous reasons, yelling out during the night, and showing OCD behaviors. I was fearing that he might have ADHD/OCD until my husband stumbled upon this website. I remember hearing stories about teenagers having horrible side effects from singulair, but didn't think it was affecting my son at 3. As I read the entries on this website I felt like they were talking about my son.

I am taking him off of it to see what happens, but now I'm nervous that his asthma will flare. He's had quite a few asthma episodes since the fall allergy season has started. I suppose he'll need to go for awhile to get everything out of his system to see if the behavior changes, and then I hope to find a new preventative. We have Pulmicort and Xopenex and an inhaler ready!

*UPDATE* Well, it hasn't quite been two weeks since I've taken James off of Singulair and - I am not kidding you - his behavior improved the FIRST day. I want anyone who reads this to know that I am not an "alarmist", I DON'T freak out over everything I read, I do a lot of research (kind of obsessive myself :), so please understand that I am not one to usually write things like this...I mean, I pushed my allergist to give it to him in the first place! There are plenty of kids out there that are fine on Singulair, but some are not. I didn't make the connection to the Singulair since the average three year old is irrational and unpredictable anyway, but I KNEW something wasn't right. It wasn't just tantrums and whatever, his overall personality had done a 180. In the last two weeks my son has returned. He still, of course, has three year old moments, but he is back to the caring, loving, curious, excited, social, happy kid I had last year. One of the worst things we were seeing two weeks ago was bedtime behavior. BAD OCD behaviors - everything in his room had to be PERFECT. The curtains couldn't have a peek of light shining through, there could be nothing on the floor, everything had to be in order. He would obsess about things (creatures) coming into his room, when we would say goodnight and close the door he would scream and cry like someone was stabbing him and was petrified. The FIRST night that we stopped the Singulair he laid his head on his pillow, said goodnight and went to sleep. Please keep an eye out for personality changes in your kids.
*November update* it's been almost two months since we took James off Singulair and we haven't seen ONE BIT of the horrible behavior that we had w/ the Singulair! Normal "three-year-old moments", but no return of the "devil child", no OCD, nighttime freak-outs, violence, or any of it.

My son is 10 years old and has been on 5 mg. singulair for 3 years. He has been getting frequent headaches,and is in the bathtub right now screaming with one! Also alot of depression.I just came upon this website accidently ,by searching the internet for what might be causing such headaches in a child. I was shocked at all of these symptoms! I am not going to give him any more singulair.But what is everyone doing to replace it and deal with their kids asthma problems? My son has had so may behavioral issues and being so unreasonable and always thinks were picking on him.To extremes! Very hars to deal with,constantly! TC

I'm posting this again for the sanity of the concerned parents on this board to let you know you're not alone:

My 5 year old son was diagnosed with mild asthma and put on Singulair. Within a few months he began having uncontrollable fits of rage, displayed self-loathing behavior, had night terrors, and was inconsolable during these episodes. He became very destructive and was a danger to himself and our family. He even talked about killing himself and would say things like "I don''t want to be in this life anymore" and "I want to kill myself". He would threaten my wife and his siblings and told them he wanted to kill them. It was a truly terrifying experience. Our pediatrician was clueless to these side affects and recommended we have our child go through a psychological evaluation. I knew this was not my child''s normal behavior so I searched the internet for Singulair side affects and found some message boards where parents just like myself were telling their stories of their children''s aggressive behavior. I immediately took my son off the drug and within a couple days he was back to his normal self. He told us that he no longer has "that feeling inside of him". Five year old children don''t even know what suicide is and to see my son talk like this was extremely frightening. He is a sweet, intelligent, loving boy who had never exhibited behavior like this until he went on Singulair. We have not seen this behavior after taking him off the drug.
