When someone is diagnosed with attention deficit hyperactivity disorder (ADHD) or a related condition, stimulant medications are often considered the first line of treatment. Two of the most widely prescribed options are Vyvanse and Adderall.
While these medications are commonly used to treat ADHD symptoms, they are not the same. Understanding the key differences between Vyvanse and Adderall can help people and their families make more informed choices alongside their healthcare providers.
This guide explores how these medications work, their benefits and risks, and what to consider if you or a loved one is navigating treatment options—or struggling with misuse.
Understanding ADHD and Its Treatment
Deficit hyperactivity disorder (ADHD) affects children, teens, and adults. Typical ADHD symptoms include difficulty focusing, restlessness, impulsivity, and challenges with organization. For adults, these symptoms may also show up as weight loss, stomach pain, or challenges managing work and daily responsibilities.
ADHD treatment often includes therapy, lifestyle changes, and ADHD medications. Among these, stimulant therapy is the most commonly prescribed and effective option. These stimulant drugs increase levels of dopamine and norepinephrine in the brain, helping regulate attention and impulse control.
What Is Adderall?
Adderall is a brand-name drug that contains a combination of mixed amphetamine salts. It comes in two main formulations:
- Adderall IR (immediate release form) – taken multiple times a day.
- Adderall XR (extended release form) – designed to last longer, typically taken once daily.
Both are FDA-approved to treat ADHD, while Adderall XR is also sometimes prescribed for adult ADHD. These medications fall under Schedule II controlled substances, meaning they have a high potential for misuse and dependence.
The active ingredients in Adderall include:
- Dextroamphetamine sulfate
- Amphetamine sulfate
- Dextroamphetamine saccharate
- Amphetamine aspartate
These are collectively referred to as free amphetamine salts or amphetamine salts. Adderall works by stimulating the central nervous system, improving focus, attention, and impulse control.
What Is Vyvanse?
Vyvanse (lisdexamfetamine dimesylate) is also a stimulant medication. It is FDA-approved to treat ADHD symptoms and to treat binge eating disorder in adults.
Unlike Adderall, Vyvanse is considered a prodrug, meaning it must be metabolized in the body before becoming active. Once digested, Vyvanse converts into dextroamphetamine sulfate, which is the active form that helps with ADHD management.
Vyvanse is available in capsule form and as chewable tablets, offering flexibility for patients who have difficulty swallowing pills. Like Adderall, Vyvanse is a schedule II drug and classified among controlled substances because of its risk of dependence.

Vyvanse vs Adderall: Key Differences
When comparing Vyvanse and Adderall, it’s crucial to examine how each works, the duration of their effects, and their impact on the body.
Onset and Duration
- Adderall IR begins to take effect within 30–60 minutes, with its effects lasting 4–6 hours.
- Adderall XR and other extended-release formulations can last up to 12 hours.
- Vyvanse generally takes longer to kick in because the body must metabolize it first, but its effects are smoother and last 10–14 hours.
Abuse Potential
Because Vyvanse requires metabolism before activation, it may have slightly less potential for misuse compared to Adderall IR. Still, both Adderall and Vyvanse can be habit-forming.
Conditions Treated
- Adderall: Primarily prescribed to treat ADHD.
- Vyvanse: Approved for ADHD treatment and also to treat binge eating disorder.
Side Effects
Common side effects of both Vyvanse and Adderall include:
- Decreased appetite
- Weight loss
- Stomach cramps or stomach pain
- High blood pressure
- Insomnia
Generic Availability
- Adderall has generic versions and a generic form available, often making it more affordable.
- Vyvanse currently does not have a generic alternative, which makes it more expensive as a brand-name drug.

Drug Interactions and Risks
Interactions between substances can have serious, even life-threatening complications. It is critical to know about potential interactions between the drugs you are taking and other substances.
Both Adderall and Vyvanse can interact with other medications. Here are some of the potential interactions.
- Monoamine oxidase inhibitors (MAOIs) – combining them with stimulants can lead to dangerous side effects like serotonin syndrome.
- Seizure drugs, proton pump inhibitors, or other stimulant medications can also interact negatively.
- Combining with alcohol or alcohol abuse can increase health risks.
Because these are schedule II controlled substances, they should only be taken under the close supervision of a healthcare provider. Physicians typically review each patient’s history and may consider other ADHD medications or other medications entirely if risks outweigh benefits.
Withdrawal, Dependence, and Addiction Risks
One of the most serious concerns is the risk of Adderall addiction and misuse of other stimulant drugs. Adderall is known to be addictive, especially in its immediate-release version. Misuse can lead to physical dependence, tolerance, and difficult withdrawal symptoms.
Adderall withdrawal may include:
- Fatigue
- Depression
- Sleep problems
- Intense cravings
Vyvanse misuse carries similar risks, though its slower onset provides a slightly different profile. Still, both Adderall and Vyvanse should only be taken as prescribed.
Clinical Considerations
In clinical drug investigation, both medications are considered effective for treating ADHD symptoms. However, side effects and patient history are important considerations.
For example:
- Those with high blood pressure may not be good candidates for stimulant therapy.
- People with weight loss struggles or stomach pain may find one drug more tolerable than the other.
- Co-occurring conditions, such as alcohol abuse or other substance use disorders, increase risks.
Choosing the right medication is highly individual. A healthcare provider may prescribe Adderall, Vyvanse, or even other stimulant medications like extended-release adderall or non-stimulants, depending on the situation.
When taking Vyvanse or Adderall, patients should avoid:
- Combining with ascorbic acid (Vitamin C). Taking this supplement close to the time you take a stimulant drug can reduce effectiveness.
- Mixing with proton pump inhibitors or certain antidepressants without medical guidance.
- Using medication without a prescription and medical supervision.
Both are Schedule II drugs and must be monitored closely to prevent misuse.

Frequently Asked Questions
1. Can Vyvanse or Adderall be used for conditions other than ADHD?
Yes. Vyvanse is also FDA-approved to treat binge eating disorder in adults. Adderall is sometimes prescribed off-label for conditions like narcolepsy. However, these uses should only be pursued under medical supervision because of the risks associated with stimulant drugs.
2. Are there non-stimulant options for treating ADHD?
Yes. While stimulant medications are the most common, other drugs such as atomoxetine (Strattera) or certain antidepressants may be prescribed. These are helpful for people who cannot tolerate stimulants or who have a history of substance misuse.
3. What should I do if I miss a dose of Adderall or Vyvanse?
If you miss a dose, take it as soon as you remember—unless it’s late in the day. Because these medications can interfere with sleep, it’s usually best to skip the missed dose if bedtime is near. Never double up doses, and always follow your healthcare provider’s guidance.
4. How do doctors decide whether to prescribe Adderall or Vyvanse?
Physicians typically review a patient’s medical history, daily schedule, co-occurring conditions, and tolerance for side effects. Factors such as blood pressure, sleep habits, and the need for longer or shorter medication coverage all influence whether Adderall XR and Vyvanse, or another option, may be chosen.
