Key takeaways
Mydayis (mixed amphetamine salts extended-release) and Adderall (mixed amphetamine salts) are both stimulant medications used to treat ADHD, but they have some key differences. Mydayis is an extended-release (ER) form of Adderall that you take once a day, and its effects can last up to 16 hours. In contrast, Adderall is an immediate-release form that you might need to take multiple times a day, with each dose lasting about 4 to 6 hours. Mydayis is not recommended for children under 6 years old, whereas Adderall can be used in children as young as 3 years old. Both medications can cause side effects like trouble sleeping and loss of appetite. Both medications are available as generics.
