Singulair and self control

My 6 1/2 year old daughter has been on Singulair for 3 1/2 to 4 years now and we have had horrible experiences! She was having night terrors, mood swings, angry issues, self control issues, crying over small things, etc. We have been to psychiatrists and psychologists who have diagnosed her with mood disorder, sensory processing disorder and anxiety disorder! Well she has recently been having stomach problems so we have been going to a GI to figure that out. I got online to research and found numerous sites that told how Singulair causes all these things in children. We took my daughter off the meds and within 3 or 4 days seen a tremendous difference! She is a totally different child! It just really frustrates me and saddens me that all these children and their families are going through all this and the doctors do not seem to care. The allergist or psychiatrist didn't believe me. They say no study has ever proven such things. I don't care what they say we as parents know our children and we are the experts when it comes to seeing how they change when on this medicine, we are the ones that live with them and are with them everyday not the doctors! I think they just don't want to lose out on their money from prescribing this drug 90% of children with allergies and asthma!

Wow. I can't even express how blown away I am by all of this.My son is 7 and has been on singulair since he was 2. He was moved to the 5 mg last year in March. The only difference between my son and all of your stories is that when he was in kindergarten we discovered a rather large arachnoid cyst in his brain that had to be drained. It was easy to blame some if not all of his behavioral problems on the location of the cyst. It is in the left temperol lobe. Having something in that region of the brain can cause behavior problems. His cyst was also big enough to push on his pituitary gland making him think he needed to use the bathroom all the time. He had a slight case of diabetes insipidus. During all of this he was complaining of headaches, fatigue, leg pain, the boy could not walk from one end of the mall to the other, he would melt down at the slightest provocation and turn into an angry little monster at around diner time. We attributed it to low sodium levels messing with his head, but his blood work never reflected someone who was THAT bad. After his surgery he had some normal depression, but in March, four months after, he became a different person. He was full of rage and anger and almost got kicked out of school. He broke things at home and lashed out at people, he said awful things. He was put on Tegretol, (that made him very sick) and Wellbutrin. Since he couldn't tolerate the tegretol they switched him to abilify. He still takes this. The one time we tried to take him off he went completely nuts again. Same kind of aggressive behavior, lashing out, no self control, crying all the time, very moody, saying things like "nobody loves me." My son is the sweetest person you will ever know. Before all of this, he would melt your heart with his kind words. Now he has been diagnosed with ADD, Aspergers, and has all of one friend at school. I go every day to eat lunch with him so he doesn't have to sit alone. I completely understand that my son will continue to have problems once this medicine is out of his system, because he does have other issues, but this morning the first thing he said to me was, "Mom it's weird, I don't know why but I feel so happy."
He has been off the Singulair for 6 days now. I called his allergist and he was VERY interested in all of this and wants to meet with me. He has always been so heartbroken by how my son has struggled. Don't think all doctors are bad. This one isn't. He is going to help me report all of this. He is really upset too. Of course he is older, been around for ever. I don't know. He cares about his patients. His receptionist said she thought they would be getting a ton of calls about this and I was the only one. Hang in there everyone. Alone we are quite together we are LOUD.

Our son is nearly six and has been on Singulair since he was 2 y/o. We put is bad behavior down to the "Terrible Two's". He has always displayed signs of poor concentration, impulsive behavior, hyper and the list goes on. Last December his PED proscribed Bactrim for a resp problem and it was just last weekend where we hit breaking point. His behavior has become aggressive along with all of the other bad behavior to the point we have been called for meetings with his new school to have a Physical assessment done.
I researched Bactrim last weekend and it was described as poison which we took him off right away and, it was pure luck i stumbled across this website to find that Singulair may be the EVIL after all.

We took him off both medications 4 days ago and we are praying we see behavioral changes soon....Already i have noticed he is more settled and relaxed while watching TV etc.

Can anyone tell me how long it takes for the medication to leave their system?

I am SOOOO glad I found this site. My daughter is 6 years old and has been on Zyrtec on and off since she was 18 months old. About two years ago we added in Singulair. Two weeks ago she was diagnosed with ADHD and Oppositional Defiant Disorder and they want to start her on meds for that. I got to thinking about when all her behavior and academic problems started and it was shortly after we started the Singulair. Before the Singulair she was a brilliant, outgoing, well-behaved happy little girl. Now she has trouble remembering short and long term, trouble concentrating, extremely fidgety, impulsive, can't complete anything she starts, extreme persistent stomach pains, diarrhea, occasional vomiting, and extreme frustration. I stopped both the Zyrtec and Singulair 4 days ago and am now reconsidering any meds for ADHD. I am going to wait and see how she does without Zyrtec and Singulair in her system. I am excited to see if there is an improvement! I had no idea these two drugs were so dangerous!

Please be careful when using this drug!!!!! My daughter is 4 years old and was on Singulair for a 1 1/2 years to control allergies and Asthma. She was also on 1 and 1/2 teaspoons of Zyrtec. She lost the last year and 1/2 of social and emotional growth. She became angry, aggressive, hyperactive, disconnected from reality, uncommunicative. She was deliberately hitting, scratching, etc. unprovoked. She retreated into a fantasy world where there was alot of "killing" and other scary things. The other kids were scared of her. Her teacher, who has over twenty years of teaching in a University Laboratory school (she knows what she is doing) said that her behavior was the most extreme she had ever seen. I took her to the Pediatrician, to a child Psychologist, and to a Physiciatrist. They were thinking ADHD and maybe Bi-Polar or ODD or worse...we were very scared. The Pediatrician said, no the drug could not be causing this. This site helped me to realize that maybe it was the Singulair. Psychologist, physiciatrist and allergist all said, yes it could be the drugs. We got her allergy tested and she was extremely allergic and started allergy shots. We took her off the Singulair and Zrytec and starting seeing changes in her behavior within a week. It has now been 5 weeks and our little girl is back...she is smiling again, happy!! and communicating! We can have a conversation with her now! It is amazing. Everyone has noticed the difference..her teachers, Dr.'s, etc. She has had a few outbursts and some hyperactivity since but they are diminishing as time goes by. I just wonder how long it will take for all the effects to be gone and how much work we have to do to teach her all the things she missed developmentally over the last year and 1/2 while her mind my blocked by this drug. They should take it off the market. It is frightening. Please beware!!!!!!!!

Has anyone heard of agitation or crabbiness as a side effect? A nurse mentioned this in passing the other day and it rang true with us but we'd never suspected Singulair as the cause.
