Vyvanse Dosage Chart: Strengths, Typical Doses, and Safety
An overview of Vyvanse (lisdexamfetamine) dosages and strengths for ADHD and binge eating disorder, how doses are individualised by a doctor, and why it must be taken only as prescribed.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician and Addiction Medicine Specialist, Phuket Island Rehab.
Vyvanse (lisdexamfetamine) is available in a range of capsule and chewable tablet strengths, commonly 10, 20, 30, 40, 50, 60, and 70 mg, and is taken once daily in the morning. For ADHD in children, adolescents, and adults, treatment is usually started at a low dose, often 30 mg per day, and adjusted by the doctor in steps, typically of 10 to 20 mg at intervals, up to a usual maximum of 70 mg per day, to find the lowest effective dose. For moderate to severe binge eating disorder in adults, the target dose is typically around 50 to 70 mg per day, reached by titration, again to the lowest effective dose. These are general figures only: the correct Vyvanse dose is always individualised by a prescribing doctor based on the person, their response, and their tolerability, and any dosage chart is only a rough guide. Because Vyvanse is a powerful amphetamine stimulant and a Schedule II controlled substance with real potential for dependence and addiction, it must be taken exactly as prescribed, never in higher doses or more often than directed, and never someone else’s prescription. Anyone with questions about their dose should consult their prescriber.
Vyvanse dosages: an overview
Vyvanse is the brand name for lisdexamfetamine, a prescription stimulant used to treat attention deficit hyperactivity disorder, ADHD, and moderate to severe binge eating disorder in adults. People often look for a Vyvanse dosage chart to understand the available strengths and typical doses. Vyvanse comes in a range of strengths and is taken once daily, and the right dose for any individual is determined by their prescribing doctor through a careful process of starting low and adjusting. This overview explains the available strengths, the typical dosing for ADHD and binge eating disorder, and how doses are individualised, but it is important to stress from the outset that this is general information only and not a substitute for a doctor’s guidance.
Crucially, because Vyvanse is a powerful amphetamine stimulant and a Schedule II controlled substance with a real potential for dependence and addiction, the dose matters not only for effectiveness but for safety, and Vyvanse must always be taken exactly as prescribed. This article provides a general picture of Vyvanse dosing, explains why doses are individualised and titrated by a doctor, and emphasises the safety principles that surround its use. The aim is helpful, accurate information for anyone wanting to understand Vyvanse dosing, alongside a clear reminder that only a prescribing doctor can determine the correct dose and that Vyvanse should never be taken in higher doses, more often, or by anyone other than the person prescribed it.
Vyvanse strengths
Vyvanse is available in several strengths, allowing the dose to be tailored and adjusted in steps. It comes as capsules and as chewable tablets, in strengths that commonly include 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, and 70 mg. The capsules can be swallowed whole or, because lisdexamfetamine is water-soluble, the contents can be dissolved in water or other suitable liquid and taken, which can help people who have difficulty swallowing capsules, and the chewable tablets offer another option. Whichever form is used, Vyvanse is taken once daily, in the morning, because it is long-acting and taking it later in the day can interfere with sleep.
The range of available strengths exists to support the process of finding the right dose for each individual. Treatment typically begins at a lower strength and is adjusted upward in steps if needed, using the different available strengths, until the lowest dose that provides adequate benefit is reached. This is why a dosage chart showing the strengths is useful for understanding the options, but the strengths themselves do not tell a person what dose they should be on; that is determined by the doctor. It is also worth noting that the strength a person ends up on can vary considerably between individuals, because people respond differently, so there is no single correct dose that applies to everyone.
| Use | Typical dosing (general guide only) |
|---|---|
| Available strengths | 10, 20, 30, 40, 50, 60, 70 mg |
| When taken | Once daily in the morning |
| ADHD starting dose | Often 30 mg/day |
| ADHD adjustment | In steps of 10-20 mg, up to usually 70 mg/day max |
| Binge eating disorder (adults) | Target around 50-70 mg/day, by titration |
| Who decides the dose | The prescribing doctor, individualised |
Typical dosing for ADHD
For ADHD, in children aged 6 and over, adolescents, and adults, Vyvanse treatment is usually started at a low dose, often 30 mg once daily in the morning. The doctor then reviews how the person responds and how well they tolerate the medication, and may adjust the dose, typically increasing it in steps of around 10 to 20 mg at intervals of about a week, until the most effective and best-tolerated dose is reached. The usual maximum dose for ADHD is 70 mg per day. The aim throughout is to find the lowest dose that adequately controls the ADHD symptoms while minimising side effects, rather than simply increasing to the maximum. The right dose varies from person to person, which is why this titration process is individualised.
It is important to understand that these figures are general guidance and that the actual dose for any individual is decided by their doctor based on their age, their response, any side effects, and their overall health. Some people do well on a lower dose, while others need a higher one. The dose may also be reviewed over time. For children in particular, doses are carefully chosen and monitored, and growth and other factors are watched. Anyone with questions about their ADHD dose, or whether it is right for them, should discuss it with their prescriber rather than adjusting it themselves, since changing the dose of a stimulant without medical guidance can affect both its effectiveness and safety.
Typical dosing for binge eating disorder
Vyvanse is also approved to treat moderate to severe binge eating disorder in adults, and the dosing for this use is somewhat different. Treatment is usually started at a low dose, often 30 mg per day, and then titrated upward by the doctor in steps toward a target dose, which for binge eating disorder is typically in the region of 50 to 70 mg per day, as this is the range found to be effective for reducing binge eating. As with ADHD, the aim is to reach the lowest effective dose for the individual, and the process is guided by the person’s response and tolerability. The maximum dose is 70 mg per day.
It is worth noting that Vyvanse is approved for binge eating disorder specifically and is not approved or appropriate for general weight loss, and using a stimulant like Vyvanse for weight loss outside its approved use carries risks and is not recommended. For binge eating disorder, as for ADHD, the dose is individualised by the prescribing doctor, and the same principles apply: take it exactly as prescribed, once daily in the morning, and discuss any questions about the dose with the doctor rather than adjusting it independently. The dosing figures here are a general guide to the typical target range, not a prescription, and only a doctor can determine the right dose for a particular person.
Why Vyvanse must be taken only as prescribed
Beyond the question of which dose is effective, the dose of Vyvanse matters greatly for safety, because Vyvanse is a powerful amphetamine stimulant and a Schedule II controlled substance with a real potential for dependence and addiction. Taking more than prescribed, taking it more often than directed, or taking it for non-medical reasons such as studying, energy, weight loss, or a high, substantially increases the risks of tolerance, dependence, addiction, and the health dangers of stimulant misuse, including effects on the heart and mental health. This is why Vyvanse must always be taken exactly as prescribed, at the dose and frequency directed, and why a person should never increase their own dose, take extra, or take someone else’s Vyvanse.
The careful, doctor-led process of finding the lowest effective dose is itself a safety measure, designed to provide benefit while limiting risk. Tampering with this, by taking higher doses or using the drug differently from how it is prescribed, undermines that safety and is exactly the kind of misuse that can lead to addiction. Anyone who finds themselves wanting to take more Vyvanse than prescribed, taking it for its stimulant effects rather than its intended purpose, or running out early, should recognise these as possible warning signs and speak with their doctor. A dosage chart can help understand the medication, but the most important point about Vyvanse dosing is to follow the prescription exactly and to involve the doctor in any changes.
Summary
Vyvanse (lisdexamfetamine) is available in a range of capsule and chewable tablet strengths, commonly 10, 20, 30, 40, 50, 60, and 70 mg, and is taken once daily in the morning. For ADHD in children, adolescents, and adults, treatment is usually started at a low dose, often 30 mg per day, and adjusted by the doctor in steps, typically of 10 to 20 mg at intervals, up to a usual maximum of 70 mg per day, to find the lowest effective dose. For moderate to severe binge eating disorder in adults, the target dose is typically around 50 to 70 mg per day, reached by titration, again to the lowest effective dose. These are general figures only: the correct Vyvanse dose is always individualised by a prescribing doctor based on the person, their response, and their tolerability, and any dosage chart is only a rough guide. Because Vyvanse is a powerful amphetamine stimulant and a Schedule II controlled substance with real potential for dependence and addiction, it must be taken exactly as prescribed, never in higher doses or more often than directed, and never someone else’s prescription. Anyone with questions about their dose should consult their prescriber.
As Dr. Ponlawat Pitsuwan, addiction medicine specialist at Phuket Island Rehab, puts it, “A dosage chart for Vyvanse is useful for understanding the strengths, but I always stress that the right dose is not something you read off a chart, it is something the doctor finds with you, starting low and going slow to the lowest dose that works. The strengths exist precisely to allow that fine-tuning. And because Vyvanse is a Schedule II amphetamine, the dose is a safety matter, not just an effectiveness one. Taking more than prescribed, or using it for energy or weight loss, is exactly how dependence develops. So the real message of any dosage chart is: take only what your doctor prescribes.”
Frequently asked questions
What are the available Vyvanse strengths?
Vyvanse comes in several strengths, as capsules and chewable tablets, commonly including 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, and 70 mg. This range allows the dose to be tailored and adjusted in steps to suit the individual. The capsules can be swallowed whole or their contents dissolved in liquid, and the chewable tablets offer another option. Whichever form is used, Vyvanse is taken once daily in the morning because it is long-acting and taking it later can interfere with sleep. The strengths themselves are a guide to the options, but the dose a person should be on is determined by their prescribing doctor, not by the chart alone.
What is the usual Vyvanse dose for ADHD?
For ADHD, in children aged 6 and over, adolescents, and adults, Vyvanse is usually started at a low dose, often 30 mg once daily in the morning, and then adjusted by the doctor in steps of around 10 to 20 mg at intervals until the most effective and best-tolerated dose is reached, up to a usual maximum of 70 mg per day. The aim is the lowest dose that adequately controls symptoms while minimising side effects, not simply the maximum. The right dose varies between individuals, which is why this titration is individualised. These are general figures; the actual dose is decided by the doctor based on the person’s response, tolerability, age, and health.
What is the Vyvanse dose for binge eating disorder?
For moderate to severe binge eating disorder in adults, Vyvanse is usually started at a low dose, often 30 mg per day, and titrated upward by the doctor toward a target dose typically in the region of 50 to 70 mg per day, the range found effective for reducing binge eating, with a maximum of 70 mg per day. As with ADHD, the aim is the lowest effective dose for the individual. Importantly, Vyvanse is approved for binge eating disorder specifically, not for general weight loss, and using it for weight loss outside its approved use is not recommended and carries risks. The dose is individualised by the prescribing doctor, and these figures are a general guide, not a prescription.
How is the right Vyvanse dose decided?
The right Vyvanse dose is decided by the prescribing doctor through a process of starting at a low dose and adjusting, or titrating, it in steps based on how the person responds and how well they tolerate the medication, until the lowest effective dose is reached. This is individualised because people respond differently, so there is no single correct dose for everyone. The doctor considers the person’s age, condition, response, side effects, and overall health, and may review the dose over time. This is why a dosage chart is only a rough guide: it shows the available strengths and typical ranges, but the actual dose must be determined and adjusted by the doctor, not chosen by the person.
Can you adjust your own Vyvanse dose?
No. You should never adjust your own Vyvanse dose, take more than prescribed, take it more often than directed, or take someone else’s Vyvanse. Because Vyvanse is a powerful amphetamine stimulant and a Schedule II controlled substance, the dose is a safety matter, and taking more than prescribed substantially increases the risks of tolerance, dependence, addiction, and the health dangers of stimulant misuse. The careful, doctor-led process of finding the lowest effective dose is itself a safety measure. Any changes to the dose should be made only by the prescribing doctor. Anyone wanting to take more, or finding it hard to stick to the prescribed dose, should speak with their doctor, as this can be a warning sign.
What happens if you take too much Vyvanse?
Taking too much Vyvanse, whether by exceeding the prescribed dose or through misuse, can cause stimulant overdose, which can involve a dangerously fast or irregular heartbeat, chest pain, very high body temperature, severe agitation, restlessness, confusion, hallucinations, seizures, and, in serious cases, life-threatening cardiac or neurological effects. Even short of overdose, taking more than prescribed increases the risks to the heart and mental health and the risk of dependence and addiction. Any suspected stimulant overdose is a medical emergency requiring an immediate call to emergency services. This is a key reason Vyvanse must be taken only as prescribed, and why a dosage chart should never be used to self-adjust the dose.
