If you’re managing ADHD, your doctor may mention medications like Adderall or Strattera. While both are used to treat attention-related symptoms, they work in very different ways.
Adderall is a stimulant, while Strattera is a non-stimulant. That distinction can make a big difference in how the medication affects you, how quickly it works, and what kind of side effects you might experience. In this guide, we’ll break down the key differences between Adderall and Strattera to help you better understand your options.
ADHD affects millions of children and adults, often making it harder to concentrate, stay organized, or follow through on tasks. It can impact school performance, work productivity, relationships, and self-esteem.
While behavioral strategies, therapy, and lifestyle adjustments can be very helpful, many people also benefit from medication. Medications like Adderall and Strattera are often used to reduce core symptoms and improve daily functioning.
Adderall is a stimulant medication that contains a mixture of amphetamine salts. It works by increasing the levels of dopamine and norepinephrine in the brain—chemicals involved in attention and impulse control.
Adderall is often prescribed as a first-line treatment for ADHD.
Adderall has been shown to improve focus, reduce hyperactivity, and support task completion. It’s generally fast-acting, with many users feeling the effects within an hour. However, responses can vary based on dose, metabolism, and coexisting conditions.
Adderall is available as:
Immediate-release tablets (lasts 4–6 hours)
Extended-release capsules (Adderall XR, lasts up to 12 hours)
Your provider will tailor the dosage based on your age, symptoms, and daily schedule.
Adderall may cause:
Loss of appetite
Insomnia
Anxiety or irritability
Dry mouth
Increased heart rate
There is a risk of dependency or misuse with stimulant medications, so they must be taken exactly as prescribed.
Strattera is the brand name for atomoxetine, a non-stimulant ADHD medication. It works by selectively inhibiting norepinephrine reuptake, which increases available norepinephrine in the brain.
Unlike Adderall, Strattera does not affect dopamine in the same way and is not classified as a controlled substance.
Strattera may take several weeks to reach full effectiveness. While it may not be as fast-acting as stimulants, it can be a good option for people who don’t respond well to stimulants, have a history of substance misuse, or have coexisting anxiety disorders.
Strattera is available as:
Capsules (taken once or twice daily)
It is typically started at a low dose and gradually increased over time.
Strattera may cause:
Upset stomach
Drowsiness or fatigue
Nausea
Dry mouth
Decreased appetite
In some cases, it may also affect mood or increase suicidal thoughts in younger patients—so close monitoring is essential, especially at the start of treatment.
Adderall increases both dopamine and norepinephrine, which can quickly boost focus and energy. Strattera only affects norepinephrine, leading to a slower onset but fewer stimulant-related side effects for some.
Adderall is a Schedule II controlled substance due to its high potential for misuse. Strattera is not controlled, which may make it a safer option for some individuals with substance use concerns.
Adderall often begins working within an hour and wears off in 4–12 hours depending on the form. Strattera may take 1–4 weeks to show full results, but can offer steady, all-day symptom control with consistent daily use.
Your doctor may take into account:
How quickly you need symptom relief
Your history with stimulant medications
Side effect tolerance
Risk factors for misuse or dependency
Co-occurring conditions like anxiety or depression
There’s no one-size-fits-all answer. Some people do best with stimulant medications, while others respond better to non-stimulants. It may take some trial and error to find the most effective option with the fewest side effects.
Adderall and Strattera are both FDA-approved treatments for ADHD but differ significantly in how they work. Adderall is a fast-acting stimulant, while Strattera is a slower-acting non-stimulant. The right choice depends on your specific symptoms, medical history, and lifestyle.

1. Is Adderall stronger than Strattera? Not necessarily. While Adderall tends to act faster, the effectiveness of either medication depends on the individual. Strattera may be a better fit for people who don’t tolerate stimulants well.
2. How long does Strattera take to work? Strattera may take 1–4 weeks to show full therapeutic effects, though some people begin noticing changes within the first week.
3. Can you take Adderall and Strattera together? This is sometimes done under medical supervision but is not common. Always follow your provider’s guidance when taking or combining medications.
4. Is Strattera safer than Adderall? Strattera is not a controlled substance and has a lower potential for misuse, but it may have other risks (like mood changes). Safety depends on your health profile and should be discussed with your doctor.
5. Can I switch from Adderall to Strattera? Yes, with guidance from your provider. Transitions between stimulant and non-stimulant medications should be closely monitored.
