Amphetamines are one of the most commonly prescribed medications to treat attention-deficit/hyperactivity disorder (ADHD). Vyvanse is a brand name for lisdexamfetamine, an amphetamine-based medication that has been used to successfully manage symptoms associated with ADHD. However, it is important to understand how long it stays in the body and if it will show up on drug tests or urinalyses. This article examines what research tells us about the duration of Vyvanse in the human body and whether or not it can be detected via urinalysis.
The pharmacokinetics of Vyvanse have been well studied through both animal models and clinical trials involving humans. Animal studies have shown that this medication breaks down into dextroamphetamine within three hours after ingestion and continues to remain in circulation for up to sixteen hours afterwards. Clinical trials conducted using healthy adults found similar results; peak concentrations of Vyvanse were observed as early as 2.5 hours post administration, while detectable levels remained up to 14 hours later. These findings suggest that Vyvanse may stay in the body longer than other stimulant medications typically used to manage ADHD symptoms such as Adderall or Ritalin.
In addition, there is evidence suggesting that Vyvanse could potentially be detected on urine drug screens even weeks after last use due its ability to be metabolized into various compounds over time. While further research needs to be done regarding this topic, understanding how long Vyvanse remains active in the body can help inform patients taking this medication about potential risks related to drug screenings and interactions with other substances they might consume during treatment.

Overview Of Vyvanse
Vyvanse is a central nervous system stimulant used to treat attention deficit hyperactivity disorder (ADHD) and binge eating disorder. It belongs to the class of medications called lysine-modified psychostimulants, which act on dopamine transporters in the brain. Vyvanse has been found to be effective in reducing symptoms associated with ADHD such as difficulty focusing and impulsivity. Additionally, it can help reduce episodes of binge eating.
Vyvanse is available in both capsule and chewable tablet forms and comes in various doses ranging from 10 mg up to 70 mg per day depending on individual needs. The medication should be taken once daily, preferably in the morning or after breakfast, as its effects last for up to 12 hours. When taking Vyvanse, it is important to follow all instructions provided by a doctor or pharmacist closely, including any restrictions related to food consumption or other drugs that may interact negatively with this drug.
How Long Does Vyvanse Last?
Vyvanse is an amphetamine-based medication used to treat Attention Deficit Hyperactivity Disorder (ADHD). It has a long half-life, which means it can stay in the body for up to 14 hours. As such, it may show up on urine tests as long as three days after last use. Factors that will affect how long Vyvanse stays in the system include age, weight, metabolism rate and dosage strength.
The effects of Vyvanse generally begin to wear off around 8-10 hours if taken orally or before 6 hours when injected. After this period of time, its presence in the body should not be detected by any drug test even though traces may still remain for several more days following ingestion. This highlights the importance of consulting with a healthcare provider about possible side effects from taking Vyvanse and being aware of how long it might take for the substance to clear one’s system before undergoing any type of drug screening procedure.
Metabolism Of Vyvanse
Vyvanse is a medication used to treat ADHD and Binge Eating Disorder. It works by increasing levels of dopamine, an important neurotransmitter in the brain responsible for regulating attention and focus. The metabolism of Vyvanse occurs primarily through enzymatic hydrolysis, with only minimal amounts excreted unchanged via urine or feces. This means that most of the drug will be broken down into its metabolites before it leaves the body. Studies have shown that Vyvanse can remain detectable in urine up to 3 days after use, while blood tests are typically positive for 2-4 days following ingestion. However, since individual biochemistry varies widely, this timeframe may vary person to person. Additionally, chronic users may find that traces of the drug remain present in their system longer than those who take it less frequently. As such, anyone being tested should consult their doctor about how long Vyvanse could potentially stay in their body and what potential risks they might face if caught taking it illicitly.
Detection Of Vyvanse In Urine Tests
Vyvanse (lisdexamfetamine dimesylate) is a stimulant used to treat attention deficit hyperactivity disorder (ADHD). Urine tests are often used in the medical field to detect and measure drugs, including Vyvanse. This section will explain how long Vyvanse stays detectable in urine, as well as other pertinent facts related to its detection:
- The half-life of Vyvanse is around 10 hours, so it can stay present in the body for up to three days after ingestion.
- However, due to differences between individuals such as age and metabolic rate, this time frame may be longer or shorter.
- Since lisdexamfetamine dimesylate metabolizes into dextroamphetamine within an hour of ingestion, urine drug screens that test for amphetamine metabolites will likely detect Vyvanse use.
- Testing for Vyvanse specifically takes approximately four days following last dose because the drug must first break down into its active ingredient before being detected.
In general then, although there are individual variations based on factors like metabolism and frequency of dosage taken, urine tests usually have a window of detection of 3-4 days after taking Vyvanse.
False Positives And Negative Results
The detection of Vyvanse in urine tests is a complex process with the potential for false positives and negative results. False positive results occur when an unrelated substance is displayed as present, while a false negative occurs when the drug is not detected even though it is actually present. In terms of Vyvanse, this could be due to its elimination from the body before testing or if there was interference of other medications that affected its presence in the sample.
It should also be noted that since Vyvanse has a long half-life, it can remain detectable for several days after ingestion. Depending on factors such as metabolism and dosage, it can take up to five days for Vyvanse to be completely eliminated from an individual’s system. Therefore, any test conducted within this time period may yield inaccurate results. It is important to consider these variables prior to conducting any type of urine analysis involving Vyvanse.

Alternatives To Vyvanse
There are alternative medications available to treat Attention Deficit Hyperactivity Disorder (ADHD) that may be more suitable than Vyvanse. These alternatives can vary in their effectiveness and side effects, so it is important to discuss any potential options with a doctor before making a decision on which medication is best for an individual patient.
| Medication | Effectiveness | Side Effects |
| Methylphenidate | High | Nausea, headaches, weight loss. |
| Atomoxetine | Moderate | Dizziness, dry mouth, decreased appetite. |
| Guanfacine | Low | Fatigue, irritability, anxiety. |
The most commonly prescribed drug for ADHD is methylphenidate. It has been shown to have the highest level of overall effectiveness compared to other drugs used to treat this disorder. However, it also has the greatest number of common side effects associated with its use such as nausea, headaches and weight loss. Atomoxetine is another popular option but has lower levels of effectiveness combined with some of the same common side effects as methylphenidate like dizziness and dry mouth; however atomoxetine tends to cause less weight loss than methylphenidate.
Guanfacine is generally considered to be the least effective among these three medications typically prescribed for ADHD treatment; yet it does not tend to produce as many adverse reactions or side effects as either methylphenidate or atomoxetine including fatigue, irritability and anxiety. Ultimately patients should work closely with their doctor when considering all possible options in order to determine what type of medication will provide them with both the most benefit and least amount of negative consequences.
Conclusion
In conclusion, Vyvanse is a commonly prescribed stimulant medication used to treat Attention Deficit Hyperactivity Disorder (ADHD) and Binge Eating Disorder. Its effects can last up to 14 hours in the body, depending on individual metabolism. The metabolite lisdexamfetamine dimesylate can be detected in urinalyses for up to four days after ingestion. False positive results are possible; therefore it is important that all other medications being taken are included when undergoing drug testing.
For those seeking alternatives to Vyvanse, there are several options available such as psychotherapy, lifestyle modifications, and other medications which may be more suitable for their individual needs. It is important for anyone taking or considering taking Vyvanse to discuss its uses with a medical professional before starting any course of treatment.
