Vyvanse (lisdexamfetamine) comes in seven capsule strengths and six chewable tablet strengths, ranging from 10 mg to 70 mg. The maximum approved daily dose is 70 mg for both ADHD and binge eating disorder. Here’s how the available doses break down and how they’re typically used.
Available Strengths
Vyvanse capsules are available in 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, and 70 mg. Chewable tablets come in the same range but top out at 60 mg, so the 70 mg option is only available as a capsule.
The two forms are interchangeable at the same strength. A 30 mg capsule and a 30 mg chewable tablet deliver the same amount of medication, so you can switch between them without any dose adjustment.
Doses for ADHD
For ADHD in both children (ages 6 and up) and adults, the typical starting dose is 30 mg taken once daily in the morning. From there, doses can be adjusted in increments of 10 mg or 20 mg at roughly weekly intervals until the right balance of symptom control and side effects is found. The maximum is 70 mg per day.
Not everyone ends up at a high dose. Some people respond well at 30 mg or 40 mg, while others need 60 mg or 70 mg. The wide range of available strengths (seven options for capsules) gives prescribers room to fine-tune. The weekly spacing between increases allows enough time to see how each dose level is working before moving higher.
Doses for Binge Eating Disorder
Vyvanse is also approved for moderate to severe binge eating disorder in adults. The dosing schedule is slightly different from ADHD. The starting dose is 30 mg once daily, but increases happen in larger jumps of 20 mg per week, with a target range of 50 mg to 70 mg daily. The maximum remains 70 mg per day. Vyvanse is not approved for weight loss on its own, only for reducing binge eating episodes.
Dose Limits for Kidney Problems
Vyvanse is broken down into its active form partly through the kidneys, so people with reduced kidney function need lower maximum doses. For severe kidney impairment, the ceiling drops to 50 mg per day. For end-stage kidney disease, the maximum is 30 mg per day. Your prescriber will determine which cap applies based on kidney function tests.
Switching From Other Stimulants
If you’re switching to Vyvanse from a methylphenidate-based medication (like Concerta or Ritalin), there is no direct dose conversion. Clinical guidance recommends stopping the first medication and starting Vyvanse at its standard beginning dose of 30 mg, then titrating up from there. The same applies when switching from other amphetamine-based medications. Because Vyvanse is a prodrug, meaning your body has to convert it into its active form after you swallow it, its effective strength doesn’t translate one-to-one from other stimulants.
How the Dose Feels Over the Day
Vyvanse is a long-acting medication designed to be taken once in the morning. The prodrug design creates a gradual release of the active ingredient over roughly 10 to 14 hours, which is why there is only one dose per day rather than multiple. Higher strengths don’t necessarily last longer, but they do produce a stronger effect during that window. If you find the medication wears off too early in the day or hits too hard in the morning, that’s useful information for your prescriber when deciding whether to adjust the dose up, down, or consider timing changes.
The 10 mg strength, the lowest available, is sometimes used as a starting point for children or for people who are especially sensitive to stimulants, even though the standard starting dose is 30 mg. It also allows for smaller step-ups during titration when 20 mg jumps feel too abrupt.
