Vyvanse-lisdexamfetamineWhat is Vyvanse (lisdexamfetamine)?

Vyvanse is a brand name prescription drug used to treat attention deficit hyperactivity disorder (ADHD) in children and adults, and binge eating disorder in adults.

 

How does Vyvanse work?

Vyvanse is a stimulant that affects the parts of the brain and central nervous system that control hyperactivity and impulses.

 

When did the U.S. Food and Drug Administration approve Vyvanse?

In 2007, Vyvanse was approved as a once-a-day medication for the treatment of ADHD for adults. In 2013, it was approved for use among children ages 6 to 17 for the treatment of ADHD. The medication was approved for the treatment of binge eating disorder in adults in 2015.

 

Is there a generic version of Vyvanse available?

Currently there is no generic version of Vyvanse available for purchase in the United States. 

 

What is the difference between Vyvanse and Ritalin?

Both drugs are stimulants used to treat ADHD. The major difference is that Vyvanse is a once-a-day drug which is typically taken in the morning and has long-lasting effects, whereas Ritalin comes in both short-acting and long-acting form.

Both drugs are classified as controlled substances, meaning they have the potential to be abused. Because of the way the Vyvanse breaks down in the body, it may have a slightly less risk of being abused than Ritalin. However, if you have a history of substance use problems, you should talk to your doctor before taking either medication.
