If you’ve been diagnosed with ADHD, your doctor might recommend a stimulant medication such as Adderall or Mydayis. While both are based on similar active ingredients, they differ in how long they last and how they’re absorbed.
This guide will walk you through how Mydayis and Adderall compare in terms of effectiveness, dosing, and potential side effects, so you can make a more informed decision with your provider. If you're prescribed either medication, you may be able to save significantly at the pharmacy using a CareCard prescription discount card, accepted at over 80,000 pharmacies with no insurance or sign-up required.
ADHD affects the brain’s ability to regulate attention, focus, and impulse control. It can interfere with school, work, relationships, and everyday life. While therapy and behavioral strategies are helpful, many people also benefit from stimulant medication as part of a larger treatment plan.
Mydayis is a long-acting stimulant medication used to treat ADHD. It contains the same mixed amphetamine salts found in Adderall but is designed to last longer throughout the day.
Mydayis uses a triple-bead delivery system to release the medication gradually over time. This extended release may help reduce the need for additional doses during the day.
Clinical trials have shown that Mydayis may help improve attention and reduce core ADHD symptoms in adolescents and adults when taken as prescribed.
Mydayis is available in extended-release capsules and is typically taken once in the morning. It is not approved for children under 13.
Some people may experience:
Decreased appetite
Insomnia
Irritability
Increased heart rate
Nausea or dry mouth
Mydayis also carries the same warning for potential misuse as other stimulant medications and should be taken only as prescribed.
Mydayis is only available as a brand-name drug, which can affect cost. However, you may be able to save by using a CareCard prescription discount card, accepted at more than 80,000 pharmacies with no insurance or membership required.
Adderall is a well-known stimulant used to treat both ADHD and narcolepsy. It contains mixed amphetamine salts and is available in both immediate-release and extended-release versions.
Adderall increases the levels of dopamine and norepinephrine in the brain, which may help improve attention, alertness, and impulse control.
Clinical trials show that Adderall may improve attention, behavior, and functioning in both children and adults with ADHD when used as prescribed.
Adderall is available as:
Immediate-release tablets (lasting about 4–6 hours)
Extended-release capsules (Adderall XR, lasting up to 12 hours)
Dosing is based on the individual’s age, weight, and treatment response.
Reported side effects may include:
Anxiety or restlessness
Sleep difficulty
Loss of appetite
Elevated blood pressure or heart rate
As with Mydayis, Adderall is a Schedule II controlled substance and should be monitored closely by a healthcare provider.
Generic Adderall is widely available, often making it more affordable than brand-name options. To further lower your out-of-pocket costs, a CareCard prescription discount card can be used at participating pharmacies nationwide.
Mydayis is designed to last longer than Adderall XR, with effects potentially lasting up to 16 hours. This extended coverage may be useful for people who need symptom management into the evening.
Mydayis is taken once daily, while Adderall (especially the IR version) may require multiple doses throughout the day.
Adderall is approved for use in children as young as 3 (IR) or 6 (XR), whereas Mydayis is only approved for individuals 13 and older.
Generic versions of Adderall are widely available and can help reduce cost. Mydayis, being brand-only, may be more expensive without a prescription discount option.

If one medication doesn’t provide the desired effects—or causes side effects—your provider may recommend trying the other. Every individual’s response to ADHD medication can vary.
Mydayis and Adderall are both effective ADHD medications that use similar active ingredients, but they differ in duration, age range, availability, and formulation. The best choice often depends on your lifestyle and treatment goals.
