The prescription stimulant Vyvanse stays in a person’s system for at least 2-3 days after last use. However, the drug has various detection windows depending on the drug test performed and may be detected in urine for about 3 days and hair follicles for up to 90 days.

The prescription stimulant medication Vyvanse (the brand name for lisdexamfetamine dimesylate) can stay in a person’s system for at least 60 hours or within 3 days after use. 

Vyvanse is used to help treat attention deficit hyperactivity disorder (ADHD) and those suffering from binge eating disorder.

This drug is a Schedule II controlled substance according to the United States Drug Enforcement Administration (DEA), meaning it has a high potential for abuse. 

Vyvanse may show on a drug test if you’re required to take one for legal or employment reasons.

The Half-Life Of Vyvanse

The half-life of Vyvanse is 12 hours which means the drug may be removed from your body in a little over 60 hours or within 3 days from the last dose of Vyvanse taken. 

However, depending on the type of drug test a person must perform, there are different detection times for the last use of the stimulant.

Types Of Vyvanse Drug Screens

Because this central nervous system stimulant drug is considered a controlled substance, there may be necessary reasons for a drug test to take place. Whether needed for legal reasons or asked by your doctor, the type of drug screening may differ.

Vyvanse Urine Tests

With a urine test, Vyvanse can be found in the system for 3-5 days. This may be the most common form of drug test performed. Once a sample is given, it will be taken to a lab to discover if traces of the drug are detected in your system.

Vyvanse Saliva Tests

As one of the more simple tests, a saliva test may be used to determine if Vyvanse has been used during the last 5-48 hours. The oral fluid on a mouth swab will be tested.

Vyvanse Blood Tests

A blood test can have the shortest detection window of up to 8 hours. With a blood test, a medical professional will use a needle to draw blood. This is a relatively fast test and detects the drug in a manner of only minutes or hours after the last dose.

Vyvanse Hair Tests

If a hair test is required, the detection window may be the longest, with the drug lasting for a month or 3 months

Typically, a hair test will involve providing a hair sample. From there, a healthcare worker will take the hair follicle to determine if there are any traces of metabolites associated with Vyvanse.

Side Effects Of Vyvanse

How long Vyvanse stays in a person’s system may also depend on the amount of the drug taken. Those who abuse Vyvanse may have a substantial amount of the drug in their system which can lead to serious side effects, including a potential Vyvanse overdose

According to the United States Food and Drug Administration (FDA), a range of side effects can also occur when Vyvanse abuse takes place, including:

  • severe weight loss
  • cardiovascular problems
  • withdrawal symptoms
  • mental health problems such as anxiety or depression
  • serotonin syndrome
  • Vyvanse addiction

Drug Interactions

Because Vyvanse is a strong stimulant, drug addiction may take place, leading a person to combine medication or substances to achieve a high. Even when taken as prescribed, certain medications should be avoided with Vyvanse.

Substances to avoid while taking Vyvanse include:

  • other stimulants such as Adderall or Ritalin
  • antidepressants such as monoamine oxidase inhibitors (MAOIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), and selective serotonin reuptake inhibitors (SSRIs)
  • alcohol
  • benzodiazepines
  • opioids
  • illicit drugs
  • supplements

Combining any of these substances with Vyvanse is a form of substance abuse.
