Mydayis

How hard is it to find Mydayis in stock?

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.

Why the Score Is Higher

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.

What This Means for Patients

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.

Who Can Prescribe Mydayis?

Mydayis is a Schedule II controlled substance. Psychiatrists, PCPs, pediatricians (for teens 13+), neurologists, psychiatric NPs, and PAs can all prescribe it. Telemedicine waivers remain in effect through 2026.

Because Mydayis is a newer medication, some providers may not be as familiar with it. If your current medication is unavailable, ask your provider about Mydayis as an alternative.

Common Side Effects of Mydayis

Most Common

• Decreased appetite
• Insomnia — particularly notable given 16-hour duration; take early in the morning.
• Dry mouth
• Headache
• Weight loss
• Nausea
• Increased heart rate
• Anxiety or nervousness
• Irritability

Less Common but Serious

• Chest pain or shortness of breath
• Circulation problems in fingers/toes

The extended 16-hour duration means side effects may persist longer than with shorter-acting stimulants. Insomnia is particularly important to monitor.

Final Thoughts on Mydayis

Mydayis fills a unique niche as one of the longest-acting ADHD stimulants available, providing up to 16 hours of coverage. This makes it particularly valuable for patients who need symptom control extending into the evening for homework, family activities, or shift work.

During the stimulant shortage, Mydayis has been in relatively better supply than more commonly prescribed alternatives like Adderall XR. The availability of a generic version has improved access further.

If you're struggling with your current ADHD medication being out of stock, ask your provider about Mydayis — it may be easier to find and could provide better all-day coverage.
