Vyvanse is a prescription stimulant drug used primarily for the treatment of attention-deficit hyperactivity disorder (ADHD) in adults and children ages six and older. Vyvanse is also used to treat moderate-to-severe binge eating disorder (BED) in adults. The medication is taken orally and starts to work more slowly than similar drugs like Adderall. It can take around two hours for the effects of Vyvanse to occur, and effects may last up to 12 hours.

How long does Vyvanse stay in your system? The primary ingredient, lisdexamfetamine may fully clear from the system within an hour. However, lisdexamfetamine metabolizes to other substances, like dextroamphetamine, which have longer half-lives and stay in a person’s system longer.

What is Vyvanse?

What is Vyvanse? Vyvanse is a psychostimulant used for the treatment of ADHD and binge eating disorder. Because it affects the central nervous system, Vyvanse is similar to Adderall. It speeds-up central nervous system processes including heart rate and blood pressure in addition to improving focus and concentration and reducing appetite.

The difference between Adderall and Vyvanse lies primarily in the fact that Vyvanse is a prodrug. A prodrug isn’t active until it’s metabolized. This effect means Vyvanse has lower misuse and addiction potential than Adderall.

There are many strengths of Vyvanse available; from 20 mg up to 70 mg doses. Some of the off-label reasons Vyvanse may be prescribed for include treating depression and daytime sleepiness.

Vyvanse Half-Life

What’s the Vyvanse half-life? Half-life is an important measure when considering prescription medications. The half-life is a measure of how long it takes the concentration of a drug to be reduced in the system by half. It takes several half-lives for most drugs to leave the system fully.

When someone takes Vyvanse, the lisdexamfetamine metabolizes into dextroamphetamine. Dextroamphetamine has a longer half-life than lisdexamfetamine. The half-life of dextroamphetamine can range from 9 to 11 hours in the average user, which means it can take around 2.5 days for dextroamphetamine to clear the system.
