How long does Vyvanse stay in your system

Vyvanse is a prescription medication primarily used to treat attention deficit hyperactivity disorder (ADHD). It is also sometimes prescribed for individuals with eating disorders. However, it is important to note that Vyvanse has the potential for addiction and is sometimes misused by individuals seeking its stimulant effects.

Vyvanse can be safely used by individuals with legitimate medical conditions as long as it is taken according to the prescribed dosage. However, it is important to be aware that Vyvanse can be detected in drug tests, which can have implications in certain situations. In this blog post, we will explore the topic of “how long does Vyvanse last” and provide information about the proper administration of this medication.

What is the Duration of Vyvanse’s Effects?

In the book Workplace Drug Testing, the duration of a drug’s presence in the body is often assessed or measured based on its half-life, which represents the time taken for normal metabolic processes to reduce the drug concentration by half. Vyvanse contains lisdexamfetamine, which is naturally metabolized into the stimulant dextroamphetamine. Lisdexamfetamine itself is detectable for only a brief period (typically a few hours). On the other hand, dextroamphetamine, with a half-life of approximately 12 hours, remains detectable for a longer duration. Dextroamphetamine, being an amphetamine-like substance, would show up on most drug tests.

As a general estimation, it is often considered that it takes around 5.5 half-lives of a drug for it to be completely eliminated from the body. However, various factors can influence the metabolism of any drug, such as a person’s weight, gender, concurrent use of other drugs, and the dosage taken.

It is crucial to consider that multiple factors can affect the detectability of Vyvanse in the system. For example, if someone were to take multiple doses of Vyvanse several hours apart, the detectability window should be based on the time of their last use rather than when they initially started taking the drug.

In terms of the duration of effects, Vyvanse typically remains effective for a range of 10 to 14 hours.
