Key takeaways
Mydayis and Adderall are both stimulants used to treat ADHD by increasing focus and reducing impulsive behaviors.
Mydayis lasts up to 16 hours, while Adderall’s immediate-release version lasts 4 to 6 hours, with an extended-release option that lasts up to 12 hours.
Adderall can be prescribed for narcolepsy, while Mydayis is only approved for ADHD in individuals aged 13 and older.
Both medications can cause side effects like trouble sleeping, decreased appetite, and increased heart rate, and may carry a risk of misuse and addiction.
If you’re diagnosed with attention deficit hyperactivity disorder (ADHD), a healthcare provider might recommend medication like Mydayis or Adderall. These two brand-name drugs are potential choices for treating ADHD symptoms because they help improve focus and impulse control. Both Mydayis and Adderall are oral capsules that contain amphetamine salts.
Both medications work by increasing the levels of certain neurotransmitters, such as norepinephrine and dopamine, in the brain. These medications may be covered by some insurance plans, though costs can vary depending on the insurance company. Although these medications contain similar active ingredients and work in similar ways, they differ in how long they last and how the body processes them.
What are the main differences between Mydayis and Adderall?
Mydayis and Adderall are brand-name prescription medications used to treat ADHD. They contain a mixture of amphetamine salts as their active ingredients. Both medications belong to a class of drugs called central nervous system (CNS) stimulants.
A key difference between Mydayis and Adderall lies in how they’re formulated and their duration of action. Mydayis is an extended-release medication with effects that last up to 16 hours. It uses a triple-bead release action that releases the medication at different times, which helps keep its effects steady and lasting throughout the day.
On the other hand, Adderall is available as an immediate-release and extended-release version (Adderall XR). The immediate-release version typically lasts for about 4 to 6 hours, while the extended-release capsules can provide effects that last for up to 12 hours.
Mydayis can be prescribed to adults and children 13 and older, while Adderall can be given to people as young as three. Adderall XR may be prescribed to adults and children six and older.

Is Mydayis or Adderall more effective?
Clinical studies suggest both medications are effective in treating ADHD. They both have similar active ingredients that help improve focus and attention. The choice between them often depends on the individual needs.
One study looked at how ADHD medications work differently for each person, depending on their needs and daily routines. It found that about 62% of children with ADHD are treated with stimulant medications. Mydayis might be a better choice than Adderall for some people because it can last up to 16 hours, providing longer relief from symptoms throughout the day.
Not all people will respond the same way to these medications. Effectiveness can vary based on a person’s medical history, including other medical conditions and medications they have. Consult a doctor or healthcare provider for medical advice on the most appropriate treatment option for you.

Drug interactions of Mydayis vs. Adderall
Both Mydayis and Adderall can have dangerous interactions with monoamine oxidase inhibitors (MAOIs). Taking either medication with MAOIs, or within 14 days of stopping an MAOI, can cause a severe increase in blood pressure (hypertensive crisis), which could lead to serious complications like stroke or even death.
Mydayis and Adderall can increase the risk of serotonin syndrome when used with drugs that affect serotonin levels, such as certain antidepressants like selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Serotonin syndrome is a serious condition that can cause symptoms like confusion, rapid heart rate, and high blood pressure.
Alkalinizing agents, like certain antacids, can increase the levels of Mydayis or Adderall in the blood, making the effects of the stimulant stronger. On the other hand, acidifying agents, such as some stomach medicines, can lower the blood levels of these medications, reducing their effectiveness.
