While they are both amphetamines, they are different medications. Your child may respond to one better than the other. I suppose if you’ve not tried either, starting by trying Adderall would make sense because if it works that’s great and you don’t have to worry about it. Adderall was bad news for my son but Vyvanse works well for him. I’ve heard the opposite from other parents so it really depends on your child.
