Good morning. I'm sorry that it's been so tough for you and your son. First I want to say that them therapist that you took him to should be strung up by his private parts and left for the vultures. I am not one who thinks that mess should be the first thing that is tried and he gave you no help at all.
Risperdone. My son, who just turned 14, has been on it for about 2 1/2 years. While life with difficult child is not perfect, and never will be, it has improved tremendously since he started this medication. Every kid is different. I know that at least one parent here said that it was the worst medication her child was ever one. For us, it helped to calm the tantrums so they happened with much less frequency, and when they did occur they were much easier to handle. The psychiatrist who prescribed it told us that it makes him hungry, so watch what he eats and he has to go to blood work every six months.
