The medication is administered as part of a treatment program, which usually includes the following:

• psychological therapy
• educational therapy
• social therapy

About ADHD

• staying still and seated;
• concentrating.

ADHD can cause problems in daily life. Children and adolescents with ADHD may have difficulties with learning and homework. It may be difficult for them to behave well at home, school, or other places.
