Overview

Vyvanse (Lisdexamfetamine) is used in patients to treat attention deficit hyperactivity disorder (ADHD) in adults and in children (6 years old and older). It is a central nervous system (CNS) stimulant medication. It may increase the ability to stop fidgeting, pay attention, and stay focused.

Doctors may also prescribe this medicine for other conditions as well, such as moderate to severe binge eating disorder (BED) in adults.

This information is for educational purposes only. Not every known side effect, adverse effect, or drug interaction is in this database. If you have questions about your medicines, talk to your health care provider.

It works by helping change certain chemicals in the brain, which professionals refer to as “neurotransmitters.” It is not yet well-understood why changing these neurochemicals results in symptom relief for the conditions this drug is commonly prescribed for.
