Vyvanse is a prescription medication used to treat attention deficit hyperactivity disorder (ADHD) in both children and adults. It works by affecting certain chemicals in the brain that contribute to impulse control and hyperactivity. Vyvanse is a central nervous system stimulant that can help increase focus, attention, and reduce impulsivity. It is available in capsule form and is typically taken once daily in the morning. Consult with your healthcare provider to see if Vyvanse is a suitable treatment option for you or your child's ADHD symptoms.
