difficult child's psychiatrist suggested using Intuniv instead of risperdal. I'm not keen on changing her medications. Both husband and I suggested waiting until next month because we want to check into this, however difficult child's biological mother, is singing Intuniv's praises because her other daugther is on it and apparently it works for her. My biggest concern is the sleepiness.. difficult child had a huge problem last year staying awake in class on the days she was at her mother's house. We don't want to go thru that again. My other concern is the material that comes with the medication says it hasn't been studied for longer than 9 weeks... no one seems to know what the long term effects could be? Any one use this longer than 9 weeks??? What can we expect??
