Leukotriene symptoms and conditions

On January 13, 2009, the FDA released a Follow-up to their March 27, 2008, Communication about the Ongoing Safety Review of Montelukast (Singulair). Included in this update is the following information:

"Post-marketing reports of neuropsychiatric events associated with montelukast, zafirlukast and zileuton have been reported to FDA’s Adverse Event Reporting System (AERS). Most of the reports of neuropsychiatric events are associated with montelukast, currently the most commonly prescribed drug that acts through the leukotriene pathway. The clinical details of some reports involving montelukast are consistent with a drug-induced effect. Because of the paucity of reports involving zafirlukast and zileuton, assessment of a drug–induced effect with these is limited. Accordingly, at this time, patients and prescribers should monitor for the possibility of neuropsychiatric events associated with these agents."

I was shocked last night on the news, when they reported that "there is no link between Singulair and suicide". I guess Merck is going to stick their heads in the sand, and let children continue to be harmed by a drug that I feel should never be prescribed to a child in the first place. I'm shocked at how young some of these children are! It makes me sad that Dr.'s, the FDA, and Merck will continue to put profit before the safety of the people being prescribed this drug and having terrible side effects from it...and most Dr.s are not fully aware of!!!!

I don't know if my 1 1 /2 year old son's being diagnosed with low igG and low IgA have anything to do with singular. He just got off it 2 weeks ago, had been on it a year. He was tested for allergies everything was negative, but tested very high positive to gliadin IgG (95.5), and positive to gliadin IgA (14.8). Is this related???? HELP!!!!!! The GI Dr want to do an endoscopy on Friday May 2. Any help, I don't want my son under anesthesia unnecessarily..................

I think I maybe just figured out the answer to these symptoms you guys are describing, with mood changes and nightmares?

From Merck Frosst website:
The team finally chose quinolein as the basis for their compound, because it has affinities with the LTD4 (leukotriene) region.

Quinolein - elsewhere it has been listed as a seratonin inhibitor...

Also, is Quinolein related to Quinine (a malarial treatment that causes nightmares and psychotic symptoms?)

What do you all think?
