I am so glad I found this site!! Our 4 year old has been on Singulair for last 3 months. The change in his behavior had been incredible on the very negative side: hyperactivity, irritability, anxiousness, aggressiveness. Somehow for 3 months we didn' t link such a behavior with Singulair. I didn' t know what to think. But then we just didn' t have Singulair at home and he was off for about 8 days and slowly we noticed a change - child started getting back to his usual self. So we discontinued taking the medicine and started researching till found the site. Too sad, but doctors prior prescribing medicine, informed the side effects are very, very rare and usually mild. After having read all the commentaries here, I do not think the awful side effects are so rare, I think they must occur quite frequently, and the bad part is: many parents might not link their kids behavior to side effects caused by Singulair. PARENTS be very cautious before giving this medicine to your kids!!!! We experienced something that I would not want anyone else to experience. Now we are just hoping things will go back to as they used to be.
