Vyvanse (lisdexamfetamine dimesylate) is a prescription medication that’s approved by the food and drug administration (FDA) and prescribed to help individuals who have attention deficit hyperactivity disorder (ADHD) and binge eating disorder. Since Vyvanse is considered a stimulant, it’s a Schedule II controlled substance, requiring a prescription from a physician.

Even though Vyvanse is primarily prescribed for the two disorders mentioned above, sometimes physicians may prescribe it off-label to help patients suffering from neurological issues that create cognitive problems or to counteract lethargy.

Learn about how long Vyvanse stays in your system, and how it is detected in blood, urine, saliva, and hair.

How does Vyvanse Affect the Brain and Body?

Vyvanse is a central nervous system (CNS) stimulant that affects the brain by increasing the levels of two neurotransmitters, dopamine and norepinephrine. Like all amphetamines, Vyvanse speeds up the messages between the brain and body by affecting norepinephrine and dopamine levels in the brain.

Norepinephrine is responsible for keeping people alert and focused, while dopamine is known as the “reward” chemical because it creates feelings of pleasure. When these chemicals are increased, individuals often feel more awake, alert, and focused.

Since Vyvanse activates the neurotransmitters responsible for focus and pleasure, it can be easy to become addicted to the drug if it’s not taken as prescribed. When taken as prescribed, Vyvanse should only be used for a short period because tolerance to the drug can develop quickly.

Vyvanse addiction can be challenging to overcome, so if you or someone you know needs addiction treatment to overcome Vyvanse abuse, contact Zinnia Health today at (855) 430-9439.

How Long Does Vyvanse Last in Urine, Blood, Salvia, or Hair?

The various types of available drug tests can also influence how long Vyvanse stays in the system. Drugs leave different metabolites in the body, which may be detectable for different periods of time depending on the drug test being used.

For instance, blood tests tend to detect substances in the system for a shorter period than hair follicle tests.

Urine tests are the most common type of drug test, and they can usually detect Vyvanse for about 24-48 hours after last use. Following is an overview of the various drug tests to help determine how long Vyvanse stays in your body:

  • Blood tests may be able to detect Vyvanse for up to 12 hours after last use. 
  • Saliva tests may be able to detect Vyvanse for up to 72 hours after last use. 
  • Hair follicle tests may be able to detect Vyvanse for up to 90 days after last use.

There may be differences in cutoff levels between labs in terms of what is considered a positive test result, which can be a factor in how long Vyvanse stays in the system. Some labs may consider a level of dextroamphetamine in the system below 50 ng/mL to be a negative result. In contrast, others may not consider a level of dextroamphetamine below 500 ng/mL to be a positive result.

What Can Affect How Long Vyvanse Stays in Your Body?

Several factors can affect how long Vyvanse stays in the system. These include:

  • The person’s weight and height
  • The person’s metabolism
  • How much of the drug was taken
  • When the last dose was taken
  • What other drugs were taken in conjunction with Vyvanse
  • The type of drug test that’s being used

It’s important to note that everyone metabolizes drugs differently, so it’s impossible to say precisely how long Vyvanse will stay in any one person’s system.

How Is Vyvanse Detected on Drug Tests?

Vyvanse is most commonly detected through urinalysis, although it can also be detected via blood, saliva, or hair follicle tests. Most standard drug panels don’t include Vyvanse, but it can usually be detected if specifically tested.

If you take Vyvanse and are worried about how long it will stay in your system, the best thing to do is to avoid taking the drug altogether.

However, if you have already taken Vyvanse and are worried about failing a drug test, there are a few things you can do to try to speed up the process of metabolizing and excreting the drug from your system. These include drinking plenty of water, exercising, and eating a healthy diet.

There’s no guaranteed way to speed up the process of metabolizing and excreting Vyvanse from your system. Everyone metabolizes drugs differently, so some people may find these methods helpful while others may not.

When worried about failing a drug test, you can avoid taking Vyvanse altogether. If you’re finding it difficult to avoid stimulant drugs even though you have a drug test, consider reaching out to Zinnia Health to hear about their treatment options for prescription drug abuse.

What Is Vyvanse Half-Life?

Half-life means the time it takes for the concentration or amount of drug in your body to be reduced by half. Typically, drugs take five half-lives to be entirely excreted from the body, but this can vary depending on the individual and the drug in question.

The half-life of Vyvanse is about 12 hours. It will take approximately 60 hours (or five times the half-life) for Vyvanse to be fully excreted from your system.

The half-life of a drug is a crucial factor because it determines how long the effects of the drug will last. For instance, if you take a dose of Vyvanse at noon and have a half-life of 12 hours, you can expect the effects of the drug to last until midnight. However, if you have a half-life of 24 hours, you can expect the effects of the drug to last until noon the next day.

How Long Does It Take to Feel the Effects of Vyvanse

The effects of Vyvanse can be felt within 30 minutes to an hour after taking the drug. However, everyone experiences the effects of Vyvanse differently. Some people may feel the effects of the drug sooner than others, and others may feel the effects for a more extended time than others.

You should also be aware of the possible side effects of taking Vyvanse. These side effects include:

  • Anxiety
  • Insomnia
  • Dizziness
  • Headache
  • Nausea
  • Diarrhea
  • Dry mouth
  • Increased heart rate
  • Decreased appetite
  • Weight loss
  • Irritability

Vyvanse is a powerful drug, and it’s essential to be aware of the potential side effects before taking it. Be sure to speak with your doctor or healthcare provider about any concerns.

How Long Vyvanse Stays in Your System

For individuals who are suffering from ADHD or binge eating disorder, Vyvanse can be a helpful tool in managing symptoms. However, it’s essential to know how long Vyvanse stays in your system and what can affect its detection.

If you misinterpret the drug’s half-life, you may be at risk of combining it with other possibly harmful substances such as alcohol. In addition, you must be aware of how long the effects of Vyvanse can last to avoid accidentally taking too much of the drug.

Overall, it’s vital to be informed about Vyvanse and to use it safely if you choose to take it.

If you’re struggling to stay within the recommended limit or experiencing any adverse effects, reach out to Zinnia Health today by phone (855) 430-9439 or email. Zinnia Health has various treatment programs to help you safely overcome substance abuse and addiction.
