Vyvanse on a Drug Screen: What You Need to Know

Vyvanse (lisdexamfetamine dimesylate) is a prescription medication used to treat attention-deficit/hyperactivity disorder (ADHD) in adults and children. It's a stimulant that works by increasing levels of dopamine and norepinephrine in the brain, improving focus and attention. However, its presence in the body can also be detected during drug screenings.

What Does Vyvanse Show Up As on a Drug Screen?

Vyvanse is a type of amphetamine, and drug screens typically test for amphetamines. So, Vyvanse will show up as amphetamine on a drug screen. This is important to understand for several reasons:

• Employment Screening: Many workplaces conduct drug tests as part of the hiring process or for random screenings. If you take Vyvanse and are required to take a drug test, it is crucial to inform your employer or the testing agency about your medication and its potential to trigger a positive result.
• Legal Issues: If you are involved in legal proceedings or have been subject to court-ordered drug tests, it is essential to be aware that Vyvanse can lead to a positive amphetamine result.
• Substance Abuse Treatment: If you are receiving treatment for substance abuse and are taking Vyvanse, your treatment provider will need to be informed of your medication use to ensure accurate monitoring and treatment plans.

How Long Does Vyvanse Stay in Your System?

The duration of Vyvanse detectability in the body varies depending on several factors, including:

• Dosage: Higher doses of Vyvanse can remain detectable for longer periods.
• Individual Metabolism: Factors like age, weight, and liver function influence how quickly the body processes and eliminates Vyvanse.
• Frequency of Use: Consistent use can prolong the detection time.
• Type of Test: Urine tests are typically the most sensitive, while hair follicle tests can detect Vyvanse for even longer periods.

According to a study published in the Journal of Analytical Toxicology, the average detection window for Vyvanse in urine is 2-3 days after the last dose, though it can be detectable for up to 7 days in some individuals [1]. However, it is essential to consult with your healthcare professional or a qualified laboratory for accurate information regarding the expected detection time in your specific case.

Important Considerations

• False Positive Results: It is possible to experience a false positive result for amphetamines due to other factors like contaminated urine samples or the use of certain over-the-counter medications that contain pseudoephedrine.
• Medical Documentation: It is always advisable to carry a doctor's note or prescription for Vyvanse to provide as evidence of legitimate use, especially during drug screenings.

Conclusion

Vyvanse will show up as amphetamine on a drug screen. Understanding this is crucial for individuals taking the medication to be prepared for potential consequences in various situations. It is vital to communicate your Vyvanse use to employers, legal authorities, and healthcare providers to avoid misunderstandings and ensure proper management of your medication.
