Vyvanse is a brand name for lisdexamfetamine, which is a medication used to treat attention deficit hyperactivity disorder (ADHD) in both children and adults. It is a central nervous system stimulant that is FDA-approved for the treatment of ADHD.

Vyvanse is a long-acting stimulant that works by increasing the levels of certain chemicals in the brain, including dopamine and norepinephrine, which play a role in attention, impulse control, and hyperactivity. By increasing the levels of these neurotransmitters, Vyvanse is believed to help improve the symptoms of ADHD, including difficulties with focus, attention, impulsivity, and hyperactivity.
