My 4yr old son has been on allegra for 2 yrs now and it seems that it wasn't doing much anymore. so our doctor prescribed Singulair. He gave us a two week trial to see if helped. Well!!! Our once happy go lucky 4yr old is now very emotional and gets upset very easily and can't stop crying ( even says he can't stop crying) when he gets upset. He is unable to console rationally when he is worked up. Today was the last dose of the two week trial and I after reading all this, it was and will be his last dose... Parents beware of Singulair I would two to one rather chase him around with a tissue.
