When it comes to treating attention-deficit/hyperactivity disorder (ADHD), stimulant medications are among the most effective options. Two of the most commonly prescribed are Vyvanse and Adderall.

Although both medications belong to the same class, they differ in how they work, how long they last, and how they affect individuals.

In this guide, we’ll explore Vyvanse vs Adderall, including their differences, similarities, effectiveness, side effects, and how to choose the right option.

What Is Vyvanse?

Vyvanse is a long-acting stimulant medication used to treat ADHD and binge eating disorder.
