Compare Mydayis vs. Dexedrine

Mydayis (dextroamphetamine/amphetamine salts) and Zenzedi (dextroamphetamine) are both stimulant medications used to treat Attention Deficit Hyperactivity Disorder (ADHD), but they have some differences. Mydayis contains a mix of dextroamphetamine and amphetamine salts, while dextroamphetamine is a single-ingredient medication. Mydayis is available in an extended-release form that lasts up to 12 hours, whereas dextroamphetamine comes in both immediate-release and extended-release forms. Mydayis is typically taken once a day, while dextroamphetamine might need to be taken more frequently depending on the form. Mydayis is also available as a lower-cost generic, but some brands of dextroamphetamine, like Dexedrine Spansule, are only available as brand-name medications. Both medications have similar side effects, such as trouble sleeping and loss of appetite, and both carry risks of misuse and dependence. However, Mydayis is approved for use in children as young as six years old, while dextroamphetamine can be used in children as young as three years old.
