Adderall and brother

My 4year old grandson has been on 20mg adderall Xr for aprox 2 months .. It has helped with his hyperness but soon after taking the drug he becomes emotionl and completely beligerant. He acts out and screams at you. This goes on for hours. Ive discussed this with doctor and he wants to up the dose.. Almost afraid to. Dont want to think that grandson could get anymore beligerant. He was hyper before the meds not beligerant. Where can I go to find more on this.?

My sister's son (age 18) was given some adderall to "try" by a friend who has ADD. It was the first time he ever tried any kind of drug or alcohol. I'm sure he took more than a normal dose (he says he took 2 - a capsule and a tablet). He had gone to dog-sit for my brother, who lives 3 hours away when he took these, and had an "episode" after taking them. He heard voices telling him to get out of the house & he didn't belong there - he was totally paranoid. He thought the neighbors were out in the streets having a meeting about him and then he thought people were hiding in the bushes watching him. He called us & told us someone had come in the house and changed all the locks on my brother's doors. My sister, parents, & I drove down to see what was going on & as soon as we walked in the door he said he thought we were "wearing wires". He was very frightened and confused. He really believed someone was in the house & in bushes, & had chewed the side of his mouth so bad he had a bad sore inside his mouth. I don't know what this drug does to people with ADD, but I would never give this drug to my child or take it myself. It appears that this kid that gave my nephew this drug needs to learn that it is ILLEGAL to give someone else your prescription medicine.

my mom is gay and so is my brother so i dont blieve u
