Singulair and possibilities

My 9 year old son only took Singuliar for about 5 weeks. He had side effects almost immediately, he was so aggressive, angry all the time, headaches, stomach ache and feeling like he was going to throw up, bad nightmares, a horrible rash, biting his nails, not focusing in school and got into trouble all the time, no appetite but his little body seem puffy all over. He has been off this medication for 3 months and he is still not 100%. He cries at little things and still has the same rash and with meds it is not going away. He had to change schools as he still was having problems in school. He just seems like he is not the same little boy and something is just not right. I do not know what to do at this point. Doctors say it should be out of his system by now, but if it is than there is permanent damage to his brain as he is just not the sharp little guy he was. We have had to take him out of all sports. Anyone else having these same problems???

As a pediatrician I write for Singulair every day.
The medication is for allergies.
Allergies cause a cascade of event that I will describe:
adenoidal swelling, leads to snoring + sleep disturbances. Poor sleep makes the child tired the next day leading to less attentiveness, hyperactivity and eventually acting out.
Almost 4 out of five kids with allergies have those subsequent symptoms, and more.
Over the years the child poor behavior his parents, teachers and peers respond of criticism/ ridicule, and punishments, cause the child to feel inadequate, embarrassed, frustrated and eventually depressed and suicidal.

Yes, Singulair does cause behavioral change but they appear within the first couple of pills, the rest is due to allergies and lack of medical care, i.e. sleep, Singulair, and Zyrtec deficiency.
Allergy shots cause 4 times the incidence of suicidally than Singulair, and Ritalin 10 times more.
Check it, it's true.

Living with our 13 year old son for the last 7-8 months has been like H--L, and now to read about all of this, we've taken him off Singulair as of last night. We've been completely at a loss why the sudden shift in his behavior, and we assume too it was hormones. Now, he's just started seeing a chiropractor for his recently diagnosed scoliosis, so we thought maybe the scoliosis was affecting his moods, which it could be, but the Singulair sounds more like it. I myself have been seeing a chiro for 19 months for a very bad back and have seen the great results (I could barely walk and was waiting to meet with a surgeon - happy to report I've not had the operation after all), and I've just finished reading a great book I encourage you all to read called One Minute to Wellness (and I'm not religious at all but this book really opens up the alternative possibilities of chiropractic care). I had heard before how chiropractic care has helped many with asthma, so we're hoping that our son's chiropractic care for his scoliosis will also help his asthma. It is worth considering. Our kids health and our sanity are worth it.

My 11 year old daughter finally told me been having suicidal thoughts since Sept. 07. Changed her class and started seeing a counselor. My 8 year old son says he can't control his body - often in a suffering tone. 8 year old son and 10 year old son having trouble concentrating in school and turning in home work - staying on task. Stopped Singulair - two weeks later counselor is ready to release daughter from thereapy. Much happier girl. 8 year old tells me he is on cloud nine - I think he trying to tell me he feels in control of himself and able to handle every day situations. 8 year old also had nightmares - gone now. I am angry that my children have taken this drug for the last 3 years every day. You always think medications are here to help -not hurt. I have learned my lesson. Dr's are quick not to blame medicine but try to rule out all other possibilities. Sometimes parents don't have time to do that. Just think, I could have lost my only daughter if this info hadn't come out.

I was on Singulair for a few years. I started seasonally and eventually stayed on it all year. It kept my mild asthma and seasonal allergies completely in control to the point where I no longer felt like I had those problems. Even after cold viruses, my peak flows never dropped as far and it didn't take as many weeks to recover peak flow. As a singer, that was very important to me.
Then I spent a year barely able to walk from the severe leg cramps and pain and swelling. My GP was stumped and I had several diagnostic and blood tests that ruled out all the possibilities she could think of. Then I called up Glaxo and asked if it could be the Singulair? Yes, in rare cases it causes edema and/or muscle cramps. My doc took me off and the problems faded away and I'm back to walking. But now my asthma is not doing as well back on the older drugs. Sigh.
