This sounds like it could be compulsive behavior. I would suggest having her evaluated for Obsessive Compulsive Disorder. It often co-occurs with ADHD. If she didn’t have these behaviors before she started Vyvanse, it could also be the medicine. My son has ADHD-I and has been on Vyvanse since 2nd grade. He is in 8th now and just started 40 mg last year, which was when he started having OCD symptoms. The MD thinks the sx were probably there all along, but they didn’t develop until after we went from 20 to 40. I’m not convinced. Unfortunately they haven’t gone away even after we took him off it.
Clonidine is supposed to be helpful for impulsive behavior if that is the cause though.
