Adderall is a combination of 4 amphetamine compounds, often reserved for second line treatment of Attention-deficit/hyperactivity disorder (ADHD), when Ritalin is not effective. It generally stays active in the body for about 12 hours, compared to 4-6 hours for Ritalin. Late evening doses should be avoided because of possible insomnia as a side effect. It is important that you discuss any change in your treatment plan with your doctor.
