Vyvanse vs Adderall
Attention deficit hyperactivity disorder (ADHD) is a highly prevalent mental health condition that affects hundreds of millions of people around the world. Over 6 million children in the US and about 4%-5% of US adults are reported to have ADHD diagnoses.1 There are certain anti-ADHD agents that may help reduce the symptoms associated with ADHD to help individuals live a better quality of life.
Vyvanse and Adderall are two anti-ADHD medications designed to help with ADHD. These stimulants are the two most commonly prescribed anti-ADHD agents. They primarily target focus issues, hyperactivity, impulsivity, and inattention. Although similar, Vyvanse and Adderall are not the same and may be used to treat different things. It is important to understand Vyvanse vs Adderall’s similarities and differences so you and your doctor can make an informed decision about your healthcare treatment plan. Genetic testing for ADHD medications may also help.
Vyvanse vs Adderall: What are They?
As part of the anti-ADHD agent drug group, Vyvanse and Adderall are both approved by the FDA to help individuals with attention deficit hyperactivity disorder (ADHD). Both or either may be useful as part of an overall treatment plan, but their effectiveness and how they interact with individuals depends on many factors including symptoms, dosage, body chemistry makeup, height, weight, other medications, and more.
What is Vyvanse?
Lisdexamfetamine (Vyvanse) is a stimulant drug and anti-ADHD agent that may be used to treat ADHD. Vyvanse contains lisdexamfetamine, which the body turns into dextroamphetamine to restore the balance of neurotransmitters in the brain to improve attention span and reduce impulsivity. In addition to being prescribed for ADHD, Vyvanse may also be used to help reduce the number of episodes for people with binge eating disorder (BED).
What is Adderall?
Just like Vyvanse, Adderall is a medication for mental wellness that falls under the class of drugs called anti-ADHD agents. Adderall is a Schedule II controlled substance that contains four amphetamine salts: Dextroamphetamine Saccharate, Amphetamine Aspartate, Dextroamphetamine Sulfate and Amphetamine Sulfate. This differs from Vyvanse, which contains only one amphetamine salt.
Similar to Vyvanse, Adderall is a stimulant medication that is intended to help increase attention span, help people stay focused on a task, control behavioral problems, and improve organization and listening skills. Adderall may also be used for narcolepsy, a chronic sleep disorder that is characterized by excessive daytime sleepiness and suddenly falling asleep.

ClarityX: DNA Testing for Medication
The DNA in our bodies contains valuable information that may be useful to determine how we will respond to certain medications. ClarityX examines DNA to uncover this information and provide patients with detailed reports on how they may react to taking certain drugs. We look for variations with the cytochrome 450 enzymes (which metabolizes over 70% of drugs). ClarityX offers two testing options with our pharmacogenetic testing:
- Mindwell test: This focuses on treatments for mental health conditions that include but are not limited to depression, anxiety, ADHD, OCD, and more.
