I have been making inquires as to how and if the fda will conduct...

Hi Flindy -

I haven't been back to this this site since May but just got an email from a mom from a post back in April asking about my son developing asthma after being on singulair. What pieces of the puzzle are you looking for exactly. I am not up on the posts and could spend too many hours reading. It can become addicting to read and my family told me I was online too much so I quit. Let me know what I can do b/c when I posted about my son developing asthma there were not too many people that responded. Many of their kids already had asthma. Thanks.

If I filed one time with the FDA , do I need to do it again, or send a letter? My son has behavioral problems, but has been off of Singulair for about 1 year. The weird thing is, when we first took him off of it, he became "a different child." Now he is much worse. I am concerned about permanent side effects/damages.

I'm wondering if you have any information on permanent and/or long term damage from use of this drug. My son was on it for four+ years, from age 2 to around 6 (Spring 2002 to early 2007). The doctors convinced me he was at risk WITHOUT this drug and I complied out of fear. I was also told singulair had an excellent safety profile. He is now 8 1/2 and is a very negative, anxious, fearful child and at times defiant and impulsive. He frequently has no appetite and suffers with insomnia. He did not start out life this way. He was an easy, calm baby and a happy toddler that napped like a champ and always slept through the night. While on singulair, I noticed that whenever I skipped a refill for any length of time my son slept and ate better, but I never connected all of the other behavioral problems to singulair, but now of course I see that eating and sleeping problems are symptomatic of a mood disorder which I believe can be caused by singulair. I mentioned this to the doctor but he had basically no reply of any value. Knowing that my son improved when we skipped doses is anecdotal evidence that perhaps there are no long term affects, however, when children exhibit behavioral problems for so long at such a young age this forms the basis of their early learning and development and then nurture takes over. In other words, their behavioral problems become learned behaviors and part of their own identity formation. Physically the drug may no longer be having an impact, but the psychological damage is done. But I'm not ruling out that the drug permanently alters brain chemistry. If you have any information on long term affects, I would appreciate hearing about what you have learned. I also believe that a class action law suit should be considered on behalf of all of the families and children that have suffered and this drug should be banned.
