Vyvanse (Lisdexamfetamine dimesylate) — Uses, Dosage, Side Effects & Safety

Drug class: Central Nervous System (CNS) Stimulant; Amphetamine derivative

Overview

Vyvanse is a prescription medication used to treat Attention Deficit Hyperactivity Disorder (ADHD) in adults and children aged 6 years and older, as well as moderate to severe Binge Eating Disorder (BED) in adults. It helps increase attention, decrease impulsiveness, and improve focus in people with ADHD. For BED, it reduces the number of binge eating days per week. Vyvanse contains lisdexamfetamine, which is a prodrug. This means it is inactive until the body converts it into its active form, dextroamphetamine. Dextroamphetamine works by increasing the levels of certain neurotransmitters (dopamine and norepinephrine) in the brain, which helps regulate attention and behavior. Key points for patients: Vyvanse is taken once daily, usually in the morning. It should be used as part of a comprehensive treatment plan that may include psychological, educational, and social measures. It is not for weight loss and should only be used under medical supervision.
