How to Save Money on Baloxavir Marboxil (Xofluza) in 2026

Baloxavir Marboxil, sold under the brand name Xofluza, is a single-dose prescription flu treatment. While it is incredibly convenient—just one dose and you are done—it can also be expensive. Without insurance, Xofluza costs between $200 and $250. Even with insurance, copays can be high.

The good news is there are several ways to lower your cost. This guide covers every savings option available in 2026, from manufacturer coupons to patient assistance programs.

How Much Does Baloxavir Marboxil Cost?

Before we talk about savings, here is what you can expect to pay:

• Without insurance (cash price): $200 to $250 for a single-dose treatment
• With insurance: Varies widely. Some patients pay a $10-$50 copay; others face higher costs depending on their plan's formulary tier.
• With a coupon card: As low as $35 with the manufacturer coupon, or around $167 with third-party coupon cards like SingleCare.

Since there is no generic version of Baloxavir Marboxil available yet, brand-name pricing applies to everyone. That is why savings programs are so important.

Option 1: Xofluza Manufacturer Coupon

Genentech, the maker of Xofluza, offers a coupon program directly on their website. Here is how it works:

• Who qualifies: Patients with commercial (private) health insurance.
• How much you save: Eligible patients may pay as little as $35 out of pocket. The coupon covers up to $70 off your out-of-pocket cost.
• Where to get it: Visit xofluza.com and look for the savings or coupon section. You can print the coupon or save it to your phone.
• How to use it: Present the coupon at your pharmacy when filling your prescription.

Important: This coupon is NOT available for patients with government insurance like Medicare, Medicaid, or Tricare. If you have government insurance, see the patient assistance section below.

Option 2: Xofluza $50 Cash Pay Option

If you do not have insurance or prefer to pay out of pocket, Genentech offers a $50 Cash Pay Option:

• Who qualifies: Patients choosing to self-pay (not using insurance).
• Cost: $50 at select participating pharmacies.
• Where to find participating pharmacies: Check the Xofluza website at xofluza.com for a list of eligible pharmacy locations.

This option can save you over $150 compared to the full cash price, making it one of the best deals available for uninsured patients.

Option 3: Pharmacy Coupon Cards

Third-party coupon cards can also lower the cost of Baloxavir Marboxil. These are free to use and do not require insurance. Some popular options include:

• SingleCare: Xofluza for around $167 (prices vary by pharmacy)
• GoodRx: Compare prices at pharmacies near you
• RxSaver: Search for Xofluza discounts by zip code
• Optum Perks: Free coupon cards accepted at most pharmacies
• BuzzRx: Compare Xofluza pricing with free coupons

To use these, simply search for "Xofluza" or "Baloxavir Marboxil" on any of these websites, find the best price near you, and present the coupon at the pharmacy. These cards work whether or not you have insurance.

Pro tip: Compare prices across multiple coupon card sites, as prices can vary significantly between pharmacies and between coupon providers.

Option 4: Patient Assistance Programs

If you cannot afford Baloxavir Marboxil even with coupons, patient assistance programs (PAPs) may be able to help:

• Genentech Patient Foundation: Provides free Xofluza to eligible patients who are uninsured or underinsured and meet income requirements. Apply through genentech-access.com or call 1-866-422-2377.
• Genentech Access Solutions: Helps with insurance navigation, appeals, and finding financial assistance. Call 1-866-422-2377.
• NeedyMeds: A nonprofit that lists assistance programs for many medications, including Xofluza. Visit needymeds.org.
• RxAssist: Another resource for finding patient assistance programs. Visit rxassist.org.

Option 5: Insurance Optimization

If you have insurance, there are ways to make sure you are getting the best coverage possible:

• Check your formulary: Look up Xofluza on your insurance plan's formulary to see what tier it is on and what your copay will be.
• Ask about prior authorization: Some plans require prior authorization (PA) before covering Xofluza. Your doctor can submit this on your behalf. Since flu treatment is time-sensitive, ask your doctor to submit the PA urgently.
• Appeal denials: If your insurance denies coverage, you have the right to appeal. Your doctor can provide a letter of medical necessity explaining why Xofluza is appropriate for you.
• Stack savings: In some cases, you can use the manufacturer coupon on top of your insurance to further reduce your copay.

Option 6: Consider Alternatives to Save Money

If the cost of Baloxavir Marboxil is simply too high even with assistance, talk to your doctor about more affordable alternatives:

• Generic Oseltamivir (Tamiflu): Available for as low as $20-$50 with a coupon. Requires a five-day course but is significantly cheaper.
• Zanamivir (Relenza): Another antiviral option. Less commonly used but may be covered at a lower tier by some insurance plans.
