Mydayis Medicare Coverage & Out-of-Pocket Cost
Mydayis is covered under Medicare Part D, with the program paying an average of $205 per prescription fill. Mydayis typically falls on Tier 3 (non-preferred brand) of standard Part D formularies. Typical copay: $40-$100 per fill, depending on plan formulary.
Your actual out-of-pocket cost depends on three factors: (1) formulary tier — your plan's specific placement; (2) deductible status — most plans require you to meet up to a $590 deductible (2025) before copays kick in; (3) coverage phase — initial coverage, then the donut hole was eliminated in 2025, replaced by a hard $2,000 annual out-of-pocket cap under the Inflation Reduction Act. Once you hit $2,000 in true out-of-pocket spending, the rest of your Part D drugs are free for the year.
Because generic Mixed Amphetamine Salts ER is available, the single biggest savings move is asking your pharmacist about generic substitution. Generics typically sit on Tier 1 with copays under $10, vs Tier 2-3 placement for brand-name Mydayis. Most states allow automatic substitution unless your prescriber writes "dispense as written."
For cash-pay or commercial insurance scenarios, compare prices using GoodRx, SingleCare, or Cost Plus Drugs before filling — discount-program prices sometimes beat Part D copays for lower-cost generics.
