Vyvanse, scientifically known as lisdexamfetamine dimesylate, stands out as a vital long-acting medication, prominently used in the treatment of attention-deficit hyperactivity disorder (ADHD) in both adults and children aged 6 to 17. It also plays a critical role in managing moderate-to-severe binge eating disorder (BED) in adults.
Originally perceived to have a lower potential for abuse compared to other ADHD medications like methylphenidate (Ritalin), Vyvanse has, however, been identified as a potential drug of abuse. This medication reaches its peak concentration in the bloodstream within 3.5 hours after intake, with its primary ingredient, lisdexamfetamine, metabolizing into longer-lasting substances in the body.
Vyvanse Half-Life & Duration
The half-life of a drug is a crucial factor in determining how long it remains active in the body. Vyvanse, comprised of lisdexamfetamine dimesylate, functions as a prodrug, which means it is inactive upon ingestion. In the body, it metabolizes into dextroamphetamine, the active agent, and l-lysine, an amino acid.
Lisdexamfetamine itself is detectable for only a few hours. In contrast, dextroamphetamine has a half-life of approximately 12 hours. Generally, it takes about five half-lives for a drug to be fully eliminated from the body. Therefore, this extended half-life of dextroamphetamine significantly impacts how long Vyvanse stays in the system, influencing its detectability in various drug tests.
How Long Does It Take For Vyvanse To Work?
Vyvanse typically starts working within 1 to 2 hours after ingestion. Its effects may vary based on individual metabolism and the method of intake. Unlike some other stimulants, Vyvanse is designed as a prodrug, meaning it requires metabolism into dextroamphetamine to become active, lowering the potential for immediate euphoric effects.
How Long Does Vyvanse Last?
The duration of effects for Vyvanse (lisdexamfetamine dimesylate) typically ranges between 10 to 14 hours, regardless of the dosage strength. This includes dosages of 20 mg, 30 mg, 40 mg, 50 mg, 60 mg and 70 mg. However, it’s crucial to note that individual responses to the medication can vary. Factors such as a person’s metabolism, body weight, age, and overall health can influence how long the effects of Vyvanse last for them specifically.
It is also important to remember that while the duration of effect does not significantly vary with the dosage, the intensity of the effects may be different. Higher doses may result in more pronounced effects, but they do not typically extend the overall duration of the drug’s action in the body.
How Long Does Vyvanse Stay In Your System?
In drug tests, Vyvanse is identified through its metabolite, amphetamine, detectable in urine for up to 5 days post-dose. Hair tests can trace it up to 90 days, while saliva tests detect it for about two days. In blood, Vyvanse is usually detectable for up to 8 hours, but its metabolite dextroamphetamine can be found for up to 60 hours. Dextroamphetamine is an amphetamine-like substance that would show up on most drug tests.
Detection of Vyvanse in Urine
In urine tests, Vyvanse itself is not directly detectable. Instead, after ingestion, Vyvanse is metabolized into amphetamine, which is the substance detected in urine. Amphetamine, a metabolite of Vyvanse, can be found in urine for up to five days following the last dose. This information is critical for individuals undergoing urine drug screening, as it provides a window of detection for recent Vyvanse use.
Detection of Vyvanse In Blood
When it comes to blood tests, Vyvanse has a relatively short detection window. Typically, Vyvanse is detectable in the blood for no more than eight hours due to its short half-life. However, as Vyvanse metabolizes into dextroamphetamine, this metabolite, with a longer half-life of about 12 hours, can be detected in the blood for approximately 60 hours. This extended detection window for the metabolite is crucial for understanding the duration Vyvanse remains traceable in blood screenings.
Detection of Vyvanse in Saliva
Saliva tests have shorter detection windows for drugs compared to urine or hair tests. These tests can detect the presence of Vyvanse or its breakdown products for up to two days post-intake. This makes saliva tests a useful tool for short-term detection of Vyvanse use, especially in settings where immediate or recent drug use needs to be assessed.
Detection of Vyvanse in Hair
Hair analysis offers the longest window of detection for Vyvanse. A typical 1.5-inch sample of hair, reflecting approximately 90 days of growth, can show if Vyvanse was taken during this period. This makes hair tests particularly valuable for assessing long-term Vyvanse usage, providing a historical record of intake over several months.
How to Get Vyvanse Out Of Your System?
Attempting to expedite the elimination of Vyvanse from the body can be risky and is generally not recommended. It’s important to remember that:
- Natural Elimination is Safest: The body will naturally metabolize and eliminate Vyvanse; this process should not be artificially accelerated.
- Hydration is Key: Staying well-hydrated can support natural bodily functions, including drug metabolism, but excessive water intake won’t significantly speed up the process.
- Avoid Unverified ‘Detox’ Methods: Many so-called detox methods found online are unproven and potentially dangerous.
- Consult Healthcare Providers: If concerned about Vyvanse in your system, especially in the context of drug testing, it’s best to consult with a healthcare provider for guidance.
- Do Not Stop Vyvanse Abruptly: If you’re using Vyvanse as prescribed, do not stop it abruptly without medical advice, as this can lead to withdrawal symptoms.
Can I Get a False Positive for Vyvanse?
False-positive drug test results can occur for stimulants like Vyvanse, mainly due to chemical similarities with other medications, including:
- Ciprofloxacin (an antibiotic)
- Aripiprazole (Abilify, an antipsychotic)
- Fluoxetine (Prozac, an antidepressant)
- Doxepin and trazodone (sleep medications)
- Phenylephrine and pseudoephedrine (Sudafed, over-the-counter nasal congestion drugs)
- Metformin (a diabetes medication)
- Ginkgo (an herbal supplement)
- Ecstasy (MDMA, an illicit drug)
How Long Does It Take Vyvanse to Kick In?
For individuals who abuse Vyvanse seeking a euphoric high, the onset of effects can be within a similar timeframe as therapeutic use—typically 1 to 2 hours after ingestion. However, this can vary based on various factors, including the method of abuse and the individual’s metabolism. Unlike some other stimulants, Vyvanse is designed as a prodrug, meaning its effects are not immediate; it needs to be metabolized into dextroamphetamine to become active. This design intends to lower the potential for immediate euphoric effects, thereby reducing its abuse potential.
However, those abusing Vyvanse might alter the method of intake (such as crushing and snorting the pills) to try to achieve a more immediate and intense high. It’s important to note that such methods are extremely dangerous and increase the risk of severe side effects, including cardiovascular problems, psychological disturbances, and even life-threatening conditions. The altered metabolism and rapid release of the drug into the system can lead to unpredictable and harmful consequences.
The desire to achieve a euphoric high from Vyvanse also significantly increases the risk of dependency and addiction. The high is followed by a crash, often leading to a cycle of abuse as individuals seek to avoid the unpleasant come-down effects. This pattern can quickly lead to physical and psychological dependence on the drug.
How Long Does Vyvanse Take to Wear Off?
The duration until Vyvanse wears off is generally aligned with its half-life and the duration of its effects. For most individuals, the therapeutic effects of Vyvanse taper off approximately 10 to 14 hours after ingestion. However, individual variations in metabolism and health conditions can influence this timeline.
Vyvanse Abuse and Treatment Options
- Medical Detoxification: The first step in treating Vyvanse abuse is often detoxification, where the body is allowed to rid itself of the drug’s influence under medical supervision. This process helps manage withdrawal symptoms, which can be uncomfortable and sometimes dangerous.
- Behavioral Therapies: Cognitive-behavioral therapy (CBT) is effective in treating stimulant abuse. It helps patients develop skills to cope with drug cravings and learn to identify and correct problematic behaviors.
- Medication-Assisted Treatment (MAT): While there are no specific medications approved to counteract Vyvanse abuse, certain medications may be used to treat symptoms of withdrawal and co-occurring disorders, such as depression or anxiety.
- Support Groups and Counseling: Participating in support groups like Narcotics Anonymous (NA) or individual counseling can provide ongoing support and guidance during recovery.
- Rehabilitation Programs: Inpatient or outpatient rehab programs offer structured treatment environments. These programs can include therapy, support groups, and educational sessions about addiction.
- Family Therapy and Support: Involving family members in the treatment process can be beneficial, as it helps build a support system for the individual recovering from Vyvanse abuse.
- Lifestyle Changes and Holistic Treatments: Encouraging healthy lifestyle changes, such as regular exercise, a balanced diet, and mindfulness practices, can also support recovery.
