Vyvanse was approved by the U.S. Food and Drug Administration (FDA) in February 2007 [1]. It became available for prescription shortly thereafter.
What is Vyvanse used for?
Vyvanse is a prescription medication used to treat Attention-Deficit/Hyperactivity Disorder (ADHD) in children aged 6 years and older, and in adults [1]. It is also approved for the treatment of moderate to severe binge-eating disorder in adults [1].
How does Vyvanse work?
Vyvanse, also known by its generic name lisdexamfetamine dimesylate, is a central nervous system stimulant [1]. It works by affecting the balance of certain natural chemicals in the brain, known as neurotransmitters. This mechanism helps to improve focus and attention and reduce impulsive and hyperactive behaviors in individuals with ADHD [1]. For binge-eating disorder, its mechanism is not fully understood, but it is thought to be related to its effects on neurotransmitters [1].
When did the patent for Vyvanse expire?
The primary U.S. patent for Vyvanse is listed as expiring in 2023 [2]. However, patent exclusivity can be complex and may involve multiple patents and potential legal challenges that could affect the timeline for generic availability [3].
Are there generic versions of Vyvanse available?
As of late 2023, generic versions of Vyvanse have begun to be approved by the FDA [4]. These generics are expected to become available, potentially impacting the market for the brand-name drug [4].
What is the difference between Vyvanse and Adderall?
Both Vyvanse and Adderall are stimulant medications used to treat ADHD. However, they contain different active ingredients. Adderall is a combination of amphetamine salts, while Vyvanse is lisdexamfetamine, a prodrug that is converted to dextroamphetamine in the body [5]. This difference in formulation can affect how they are absorbed and their duration of action.
What are the potential side effects of Vyvanse?
Common side effects of Vyvanse can include decreased appetite, dry mouth, insomnia, anxiety, irritability, weight loss, and increased heart rate [1]. More serious side effects can occur, and it is important to discuss these with a healthcare provider.

Vyvanse is manufactured by Takeda Pharmaceuticals [1].
What is the cost of Vyvanse?
