Comprehensive medication guide to {drug} including estimated pricing, availability information, side effects, and how to find it in stock at your local pharmacy.
Mydayis is a prescription stimulant medication used to treat ADHD in adolescents (ages 13+) and adults. It contains the same mixed amphetamine salts as Adderall XR but uses a triple-bead extended-release system that provides up to 16 hours of coverage — significantly longer than Adderall XR's 8–10 hours.
Originally manufactured by Shire (now part of Takeda), Mydayis was FDA-approved in 2017. A generic version is available, making it more accessible and affordable.
Mydayis is particularly beneficial for patients who need all-day coverage extending into evening hours — such as those with work, school, or family obligations that extend beyond the typical workday.

Mydayis contains mixed amphetamine salts (a combination of amphetamine and dextroamphetamine). It works by increasing the release and blocking the reuptake of dopamine and norepinephrine in the brain, improving focus, attention, and impulse control.
Mydayis's triple-bead system releases medication in three phases: an immediate-release component for rapid onset, followed by two delayed-release components that extend the duration of action to approximately 16 hours. The beads have different coating thicknesses that dissolve at different rates.
Effects begin within 2 hours and can last up to 16 hours, making it one of the longest-acting stimulant medications available.
Mydayis is available in extended-release capsules in the following strengths:
Mydayis uses a triple-bead delivery system that releases medication in three phases throughout the day, providing up to 16 hours of symptom coverage. This makes it one of the longest-acting ADHD stimulants available.
Mydayis is approved for patients ages 13 and older (not approved for children under 13). Capsules should be taken in the morning and can be swallowed whole or opened and sprinkled on applesauce.
Mydayis (mixed amphetamine salts extended-release) is a newer, long-acting ADHD stimulant that provides up to 16 hours of coverage. We've assigned it a findability score of 55 out of 100, meaning patients should expect moderate difficulty but generally better availability than more commonly prescribed stimulants.
Mydayis is less commonly prescribed than Adderall XR or Vyvanse, which actually works in its favor during the shortage. Because fewer patients are prescribed Mydayis, pharmacy demand is lower and supply-demand imbalance is less severe. A generic version (amphetamine mixed salts XR) has been available, making it more affordable and accessible.
Many pharmacies and specialty pharmacies can stock or order Mydayis within a few days. Providers have increasingly turned to Mydayis as an alternative when Adderall XR is unavailable, which has modestly increased demand.
Patients may need to call 2–5 pharmacies to find Mydayis in stock. Specialty pharmacies tend to have better availability. The generic version is often easier to find than brand-name Mydayis.
