Vyvanse can stay in your system for about 60 hours after the last dose. Recent Vyvanse use can show up on drug tests for as long as 90 days later.

Vyvanse is a prodrug and central nervous system stimulant that can treat attention deficit hyperactivity disorder (ADHD) and binge eating disorders. Its main ingredient is lisdexamfetamine dimesylate, which breaks down into dextroamphetamine in the body.

Testing for Vyvanse may be a part of a substance abuse treatment program, a requirement from your employer, or in a hospital setting for patients showing adverse effects of Vyvanse.

Half-Life Of Vyvanse

Half-life is the period of time it takes for a substance to decrease to 50 percent of its maximum concentration after being ingested. After about five half-life cycles, most substances are completely eliminated from the body.

Lisdexamfetamine dimesylate, the main component of Vyvanse, has low absorption rates and a short half-life in the body. Dextroamphetamine, Vyvanse’s main metabolite and active ingredient, has a significantly longer half-life of about 12 hours.

After about 60 hours, dextroamphetamine may leave a person’s system.

Vyvanse is an extended-release stimulant drug, and its effects can last for about one day. Potential side effects of Vyvanse, such as high blood pressure, increased heart rate, weight loss, and mental health problems, may last for longer after the last dose.

Drug Testing For Vyvanse

Vyvanse may show up on several forms of drug tests. Lisdexamfetamine has a short half-life and detection window, so drug screenings may not test for it. Dextroamphetamine may have a longer detection time compared to lisdexamfetamine due to its longer half-life.

Drug tests for Vyvanse may detect either dextroamphetamine or amphetamine.

How Long Does Vyvanse Stay In Your Urine?

Urine tests can detect Vyvanse for about 3 days after the last dose. Urine tests may test for general amphetamine or methamphetamine use, instead of specific prescription drugs such as Ritalin or Adderall.

Urine tests are a common testing method for general healthcare providers, drug addiction treatment programs, and law enforcement. They are convenient and less invasive compared to other methods.

Urine test results can be tampered with by the subject, but tampering with a drug test may result in fines or jail time.

How Long Does Vyvanse Stay In Your Blood?

Blood tests can detect Vyvanse use for about 2 days. Blood tests have shorter detection times than urine tests on average.

Blood tests may be used in similar circumstances as urine tests. Patients who show signs of substance use disorders may be subject to a blood test by their employer or healthcare provider.

How Long Does Vyvanse Stay In Your Saliva?

Saliva tests can detect Vyvanse for about 1 day after the last dose.

Saliva tests are less invasive than urine or blood tests on average. They can also detect multiple substances in one swab. It can be difficult to falsify results for a saliva test, as the testing process itself is supervised.

How Long Does Vyvanse Stay In Your Hair?

Vyvanse use can be detected in hair follicles for up to 90 days after the last dose. Vyvanse metabolites may reach hair through the bloodstream and remain there as the hair grows out, but these tests are less common than others.

Treatment Program For Vyvanse Abuse

Vyvanse is a schedule II controlled substance, according to the U.S. Drug Enforcement Administration. The drug itself may stay in a person’s system for over 2 days, but the potential for serious side effects may last for weeks, months, or even years.

If Vyvanse is a target of drug abuse in your life, you may find it difficult to stop despite negative health effects. A professional addiction treatment program can identify and address difficulties that you may have with continued use.
