This is my first post, but I've been reading posts and gotten alot of ideas and insight into my difficult child. difficult child is on .5 mg of risperdal twice a day and 1mg of Tenex at night. The risperdal has been a god send.. Wonderful results.. but her weight is getting out of control. She's gained 20 pounds since starting the medication in October. We knew this was a side effect but none of the docs were concerned because difficult child was so small. Well now she's caught up to her peers in weight and height, but I don't see her appetite slowing down. Has anyone else had this problem and what did you do?
