difficult child 1 was taken off of respidal because it was making him more aggresive and agitated. He has been cursing me and his father and being extremely disrespectful to his teacher. He got into a fight with 3 other boys on thur last week, he said that they started it, and I believe him. His psychiatrist put him on Invega and I do not know much about it. Is there any thing I should know?
