Medicare Part D Coverage for Migraine Drugs
All 10 migraine drugs in this comparison are dispensed under Medicare Part D. Total Medicare spending reached $4.6B in the latest reporting year, averaging $443.10 per prescription fill.
Your out-of-pocket cost depends on three factors: (1) your plan's formulary tier — generics typically land on Tier 1 ($0-$10 copay), preferred brands on Tier 2 ($30-$50), and specialty drugs on Tier 4-5 (often 25-33% coinsurance); (2) your deductible status — most plans require you to meet up to a $590 deductible before copays apply; (3) the coverage phase — initial coverage, coverage gap, or catastrophic. As of 2025, Medicare Part D caps total annual out-of-pocket at $2,000 under the Inflation Reduction Act.
The 10 drugs with generic availability are usually the most cost-effective starting point — ask your prescriber whether a generic substitution is clinically appropriate.
Drug costs vary dramatically within this category. Vyepti (Eptinezumab) at $944.00 per claim is 52x more expensive than Sumatriptan (Sumatriptan) at $18.00 — yet both treat migraine. Therapeutic substitution within the same drug class is often the single biggest savings lever, and it requires only a prescriber conversation, not a plan change.

Talk to your doctor about therapeutic alternatives in the same drug class.
