My son is 6 years old, and I started crying when I read the above stories. My son, too, was a completely different person when he took Singulair. Prior to taking it, we had a wonderful, close relationship and he was a well behaved child that excelled in school and got along well with friends. His behavior changed for the worse, but until now, I didn't connect it to the use of Singulair-I thought maybe he had childhood depression but didn't know why, as his life is stable and happy, and no major life changes had happened to cause the mood swings. He would say his life was bad and he wanted to die for the slightest thing, he would say he hated us and punch us for just simple time outs that he usually complied to and he never ever hit us before. I have had him off of Singulair the past month, and give him Zyrtec occasionally when he really needs it, and he has not had one major moody episode, and he is back to his happy self again. I am joining the class action lawsuit above.
