Singulair and testosterone

I have only been taking singulair for about a month. I have noticed that I have become more irritable, grouchy, hateful and just numb, not really wanting to be around anyone, not caring about anyone else's feelings much. I also noticed I have become extremely lethargic, to the point of falling asleep at work as well as heart palpitations and stomach pains. I just started new birth control pills so at first assumed they were causing these side effects, that is until I looked up the side effects of this drug! I have over half of the side effects so I stopped it immediately and can already tell a difference in my mood. I have to sons age 11 and 14, both who have asthma and allergies. The took this medication for a few years with no side effects but have not taken it for about a year now. My youngest son however, has been diagnosed with ADHA and ODD and possibly BiPolar disorder. As I read the other posts, I realize the description of how their children act while on this drug is exactly how my son acts. I wonder if there can be irreversible permanent damage from taking this medicine? He has been on a number of ADHD drugs, none have helped except to make him stop eating and lose weight and he is small for his age, so I have taken him off everything. Has anyone else out there experienced what could be permanent damage from this drug in their children? Even after being off the drug for a year or so? If it could make me miserable within a month, what can it do when one takes it for years? Its sometimes hard to tell the effects of medicine on small children. My son prob starting taking it around 4 yrs old and took it til he was about 8 or 9. Just wondering if anyone else out there has had this happen to them or their children.

My son began taking singulair when he was 6. About that time we were hading into the school years. He was labeled as a "special" child from that time on. Impulsive, aggressive, angry, anti-social, etc. He had a hard time focusing at school and every day was a battle. About 5th grade, after 3 schools, he was diagnosed with ADHD. I never, ever thought that it could be this medication. He was on it for about 4 years off and on during allergy season. I transferred him to a private school for children with behavioral issues and as time went on through therapy and special schooling it seemed to get better. I look back now and see that our "good" times were when he finally went off it for good. The beginning of his Freshman year was great! He had a 3.58 GPA, making friends and finally happy. The unfortunate thing is now that puberty has really kicked in, we are back to the old behaviors but much worse. Impulsive, angry, anxious, afraid of the dark, afraid of death. Violent thoughts, impulsive and very unhappy. I can see now that my son never had ADHD. He was misdiagnosed because thier were no warnings at that time. I don't think it ever "goes away". Even after years of being off of it. Something with the puberty hormones is re-triggering this behavior. IT IS LONG TERM!!!!! Even after discontinued use. Please, please keep an eye on your children. I AM SO ANGRY FOR HIM!! Also, for me. Special school $400 month, psychologist appointments, $300 month, my poor Son in a dark place I can't get him out, PRICELESS. . .I want my Son just to be happy. Thank you all for sharing your stories, it gives me strength that I need for him.

I have been taking Singulair for two years. Initially I noticed problems with sleeping the entire night. I also would wake with a terrible headache and I was irritable and wanting to actually punch the next dude that looked at me sideways ( I have been bodybuilding for 15 years and already have a ton of testosterone) ( I took the meds at bedtime) The last several months on Singulair I noticed a constricting of the throat and a sore throat. blurred vision and an upset stomach that has developed into what I believe is GERD. Since I have stopped the meds It was only 2 days before I became docile in mood, my vision is no longer blurred and my stomach is healing. I have lost 4 Lbs ( I have always weighed myself daily) I sleep the entire night and my throat is no longer constricted. I am sure for some people this medicine would not be a problem, but for me..as the Frenchman said in the movie "Along came Polly".."NO WAY JOSE!"
