Typical Keytruda Costs Without Discounts
Keytruda (pembrolizumab) lists at around $11,000-$12,500 per single-dose vial (100 mg/4 mL), depending on the pharmacy and location. A standard 3-week cycle for a 70 kg patient at 200 mg requires one vial, totaling $150,000-$200,000 annually without insurance or aid.[1][2]
Savings Through Patient Assistance Programs
Merck's official Keytruda Savings Card cuts out-of-pocket costs to $0 for eligible commercially insured patients on up to 12 infusions per year (max $25,000 savings). Eligibility requires household income under $100,000 and no government insurance.[3]
Merck Patient Assistance Program provides it free for uninsured or low-income patients (income ≤500% federal poverty level), potentially saving 100% of costs.[4]
Manufacturer Coupons and Copay Cards
- Keytruda Savings Program: Reduces copays to $0 for the first 6 doses, then $1,500 max per dose (savings up to $10,000+ per cycle for high-deductible plans).[3]
- GoodRx coupons drop cash prices to $9,500-$10,200 per vial at select pharmacies, saving $1,300-$2,000 per dose vs. list.[5] SingleCare offers similar at $9,400 per vial.[6]
| Scenario | List Price (Annual) | With Discount | Savings |
|----------|---------------------|---------------|---------|
| Cash pay, no aid | $200,000 | $114,000 (GoodRx, 12 vials) | $86,000 |
| Insured, high copay | $25,000 copay | $0-$18,000 (Savings Card) | $7,000-$25,000 |
| Uninsured, low income | $200,000 | $0 (Merck PAP) | $200,000 |
How Insurance and Medicare Coverage Changes Savings
Commercial insurance covers 80-90% after deductibles; discounts then handle the rest, often to $0. Medicare Part D patients save via Extra Help (up to $4,000/year reduction) or Merck's card ($0 copay for full-year supply).[7] Without aid, Part D copays hit 25% ($3,000-$5,000/month early in coverage gap).
Eligibility Requirements for Maximum Savings
