My 30yo daughter has had ADHD since 2nd grade. She was on Adderall XR for years and now is back on Adderall and titrating up. She is up to 50mg twice a day. How high have other patients gotten before they have reached maximum benefit from the med without dangerous side effects? She is doing this with supervision from psychiatrist. She takes her BP at least daily and it runs 120s/70s.
