Some may remember, I've posted a few threads about my niece. Mom has been trying to be consistent and firm with her but she fights her every step of the way. Calls her B word and tells her she can't tell her what to do. She has been communicating with her Bio-Mom which is against the no-contact order and we worry this may have something to do with her behavior- not a complete reason, but a contributing factor. Niece is on 40mg Vyvanse and 1mg Intuniv. Her dr. put her on that and said it was the best for her age and being female. Anyone have experience with these two medications (specifically vyvanse) in an ADD child? Mom says that ever since she got back from my house she has been excessively angry. She wasn't this bad before she left. I know I didn't do anything to make her angry, so I am not sure what is causing it ever since she got back. Is it common for a medicine such as Vyvanse to stop working after a period of time? Niece has been on it for about 6 months. Mom is going to speak with her dr. and see if she can try her on Risperidone (I think that's what it is.. she said it like "Risp-i-done"). My 10 year old nephew and 8 year old niece are on this medicine along with intuniv and Mom says their anger issues have significantly depleted. Although, as stated, my niece is on vyvanse and intuniv. The 10 and 8 year old were diagnosed with ADHD, while my older niece was diagnosed with ADD. And Mom believes she received the ADD versus ADHD diagnosis because she said she didn't have as much energy- but the issue is that she simply likes to stay up late at night.. and the other medicines would put her to sleep. So she may very well have ADHD. Mom said she does not think that another full evaluation. is necessary but she will ask what her doctors. think. I mentioned to her to see a neuropsychologist as many of you recommended. (did I get that right? Neurophchologist?) so she will look into that. Anyways- given this information, can you recommend any medications that may have helped you, if your children have these increasing anger issues? Anything that does not work?
