Oseltamivir cost with Medicare in 2026

Each Part D plan has its own list of covered drugs and copays, so what you pay for oseltamivir depends on your plan (Medicare Plan Finder). In 2026, Part D plans can have a yearly deductible of up to $615, and your out-of-pocket costs for covered drugs are capped at $2,100 a year ($2,400 in 2027) (Medicare.gov).

Savings programs from the maker

eDrugSearch does not offer its own Oseltamivir coupons. We found no Genentech copay card or patient assistance program for Tamiflu, and no maker coupon for the generic. These programs can lower what you pay:

• Medicare Extra Help: if you have Medicare and limited income, Extra Help lowers what you pay for prescriptions. (Social Security)
• Medicare Prescription Payment Plan: a free Medicare option that spreads your drug costs into monthly payments across the year. It doesn't lower the total, but it can make costs easier to manage. (Medicare.gov)
• Costco Pharmacy member prices: Costco publishes member prices for many prescriptions, for people with a Costco membership. Non-members can also use Costco pharmacies and pay the regular cash price. Member prices can't be used with insurance, Medicare or Medicaid claims. (Costco Pharmacy)
• Amazon Pharmacy Prime and RxPass: Amazon Pharmacy offers Prime members discounts on many prescriptions, and RxPass, for Prime members, covers a set list of generics for a flat monthly fee. Prime is not required to use Amazon Pharmacy. Prime savings have limits for people with Medicare, Medicaid or Tricare, and RxPass is not open to people with Medicaid or CHIP. (Amazon Pharmacy)
• Discount cards: Discount cards (for example GoodRx or SingleCare) may lower the price at local pharmacies; prices vary by pharmacy and ZIP code.

When people choose brand Tamiflu

Some people get brand Tamiflu instead of generic oseltamivir. Common reasons:

• A prescription marked “dispense as written” (or “brand medically necessary”) tells the pharmacy to fill brand Tamiflu, not a generic. State laws set the rules for generic substitution.
• Brand Tamiflu's list price is many times the generic's, and we found no Genentech savings card for it.
• Some insurance and Medicare drug plans cover the brand and the generic at different copays, or cover only one of them. Your plan's drug list shows which.

Your prescriber decides which medicine is right for you.

What is Oseltamivir used for?

Oseltamivir is a flu antiviral (neuraminidase inhibitor), the same medicine as in Tamiflu. The FDA label for Tamiflu (DailyMed), which the generic labels follow, lists these uses:

• Treatment of acute, uncomplicated influenza A and B in patients 2 weeks of age and older who have had symptoms for no more than 48 hours.
• Prevention of influenza A and B in patients 1 year of age and older.

The label says oseltamivir is not a substitute for a yearly flu vaccine. Generic oseltamivir comes as 30 mg, 45 mg and 75 mg capsules and as an oral suspension. It has no boxed warning. The label warns about serious skin and allergic reactions, and about confusion or abnormal behavior reported mostly in children with the flu. Check the label that comes with your medicine. Your prescriber decides which medicine is right for you.
