What is vyvanse prescribed for

Overview

Vyvanse (lisdexamfetamine dimesylate) is a prescription stimulant medication used to treat Attention-Deficit/Hyperactivity Disorder (ADHD) and Binge Eating Disorder (BED). It belongs to a class of medications called sympathomimetic amines, which work by affecting chemicals in the brain and nerves that contribute to hyperactivity and impulse control. Vyvanse is one of the most commonly prescribed ADHD medications in the United States.

ADHD Treatment

The primary use of Vyvanse is treating ADHD, a neurodevelopmental disorder characterized by persistent patterns of inattention and/or hyperactivity-impulsivity. ADHD affects both children and adults, impacting their ability to focus, organize tasks, and manage impulses. Vyvanse is FDA-approved for children ages 6 and older and adults with ADHD.

When taken as prescribed, Vyvanse helps improve focus, attention span, and impulse control. It typically begins working within 1-2 hours of administration and provides symptom relief throughout the day, making it suitable for school, work, and daily activities.

Binge Eating Disorder Treatment

Vyvanse is also FDA-approved for treating Binge Eating Disorder (BED) in adults. BED is characterized by recurrent episodes of consuming large quantities of food while feeling a loss of control. Vyvanse reduces the frequency of binge eating episodes and helps patients develop healthier eating behaviors.

This is a unique indication that distinguishes Vyvanse from many other ADHD medications, making it one of the few FDA-approved pharmacological treatments for BED.

How Vyvanse Works

Vyvanse is a prodrug, meaning it is inactive until metabolized in the body. Unlike other ADHD stimulants, lisdexamfetamine must be converted to dexamphetamine in red blood cells to become active. This design theoretically reduces abuse potential compared to immediate-release stimulants.

The medication increases levels of dopamine and norepinephrine in the brain—neurotransmitters essential for attention, motivation, and executive function. This enhancement helps regulate brain activity in areas responsible for focus and impulse control.

Dosage and Administration

Vyvanse is available in capsule form in doses ranging from 10mg to 70mg daily. Most patients take a single daily dose in the morning, with effects typically lasting 10-13 hours. Dosing is individualized based on patient response and tolerability.

Common side effects include decreased appetite, dry mouth, insomnia, and elevated heart rate. More serious side effects are rare but can include increased blood pressure, heart palpitations, and psychiatric symptoms.
