Vyvanse is a medication that is commonly prescribed to treat attention deficit hyperactivity disorder (ADHD) and binge eating disorder. It is a stimulant that works by increasing the levels of dopamine and norepinephrine in the brain. While Vyvanse can be an effective treatment option, it is important to understand how long it stays in your system to avoid any potential side effects or interactions with other medications.
How Long Does Vyvanse Stay in Your Blood?
The half-life of Vyvanse is approximately 10 to 12 hours. This means that half of the drug will be eliminated from your bloodstream after this amount of time. However, it can take up to five half-lives for the drug to be completely eliminated from your system. Therefore, it can take anywhere from 50 to 60 hours for Vyvanse to be completely eliminated from your bloodstream.
How Long Does Vyvanse Stay in Your Urine?
Vyvanse can be detected in urine for up to three days after the last use. The length of time that Vyvanse stays in your urine can vary depending on factors such as your age, weight, and overall health. Additionally, if you are a chronic user of Vyvanse, it may take longer for the drug to be eliminated from your system.
How Long Does Vyvanse Stay in Your Hair?
Vyvanse can be detected in hair for up to 90 days after the last use. This is because the drug is stored in hair follicles as it grows. Hair testing is not a common method of drug testing, but it can be used in certain situations such as legal or employment-related drug testing.
