How Much Do Tamiflu and Xofluza Cost? A Guide for an Early Flu Season

Flu arrived early this year. Generic Tamiflu often costs about $12 to $26 with a discount, and Xofluza has a $50 cash offer. The new generic Xofluza does not appear to be on sale yet.

The Short Answer

Flu season started early in 2026. Antiviral medicine works best when you start it within 48 hours of your first symptoms, so you may not have time to shop around for days. Know your options now.

Generic oseltamivir (Tamiflu) is the low-cost choice for most people. A 10-capsule course of the 75 mg strength recently showed prices from about $12 to $26 with a discount, compared with about $158 at full retail. Brand-name Xofluza is a single dose, and it has a $50 cash offer. The FDA approved a generic Xofluza in June, but we found no evidence that pharmacies sell it yet.

Why This Flu Season Is Different

The CDC's FluView report for the week ending October 24 shows activity "higher than typically observed at this time of year." About 7.6% of flu tests came back positive. The hospitalization rate was the highest for that week of the season since 2010-11.

Almost all the flu A viruses that the CDC subtyped were H1N1. This H1N1 strain picked up a new mutation, according to researchers quoted by NBC News. The CDC says it is too early to know what this means for vaccine effectiveness. An early start also does not prove that the season will be severe. Experts still advise a flu shot, because the vaccine covers three strains and takes about two weeks to reach full protection.

Compare the Four Flu Antivirals

The FDA approved four flu antivirals. The CDC recommends oseltamivir most widely. Your prescriber chooses the right drug and dose for your age, weight, health, and pregnancy status.

Some warnings apply before you choose. Zanamivir can cause serious breathing problems in people with airway disease. The CDC does not recommend baloxavir during pregnancy or while breastfeeding. It also does not recommend baloxavir alone for people with severe immune suppression, or as routine treatment for hospitalized patients. Do not take baloxavir with dairy products, calcium-fortified drinks, or laxatives, antacids, and supplements that contain calcium, iron, magnesium, selenium, or zinc.

What Generic Tamiflu Costs Right Now

These prices are for oseltamivir 75 mg, 10 capsules, which is a common adult course. We checked them on November 3, 2026. Prices change often and differ by location.

The gap between the top and bottom rows is the reason to compare. The same capsules can cost about 13 times more if you pay the full price. Children often take a liquid form or a lower strength, so the price will differ. Search the exact form and strength on your prescription.

An FDA shortage search showed no oseltamivir shortage on November 3. We found no national report of one this season. However, a single store can still run out during a local surge. Call ahead before you drive to the pharmacy.

What Xofluza Costs

Xofluza usually lists at more than $200 for one dose. GoodRx reported average retail prices of about $222 to $226. Two Genentech programs can lower that cost, according to the Xofluza coupon page, which we read on November 3.

• The $50 cash offer. You pay a flat $50 through a listed pharmacy. The page shows Costco (members only), Alto, and Cost Plus Drugs. You cannot combine this offer with insurance.
• The savings coupon. You may pay as little as $35, and the coupon takes off up to $70. It excludes Medicare, Medicaid, and TRICARE.

Genentech can change these terms without notice, so confirm them before you fill. Also consider the total cost. Xofluza at $50 can cost more than generic oseltamivir, but one dose may suit someone who struggles with a five-day schedule. Ask your prescriber if the choice matters for your case.

The Truth About Generic Xofluza

News reports in June said that a lower-cost generic would arrive for this flu season. The approval is real. The FDA approved Norwich Pharmaceuticals' generic baloxavir on June 17, 2026, in 40 mg and 80 mg strengths.

An FDA approval does not put a drug on the shelf. Bloomberg Law reported in 2025 that a patent deal blocks sales until a confidential date or October 2039, whichever comes first. The real date is not public. On November 3, we found no Norwich product in federal drug listing data or on DailyMed, the federal label database. Drugs.com reports that the generic "does not appear to be commercially available."

We cannot rule out a quiet launch. If a pharmacy offers you generic baloxavir, ask for the price. Otherwise, do not delay treatment while you wait for it.

What to Do When Flu Symptoms Start

1. Note the time. Write down when your symptoms began. The 48-hour clock starts then.
2. Call a prescriber the same day. A telehealth visit can work if your regular office has no openings.
3. Ask if a pharmacist can help. Some states let pharmacists test for flu and prescribe treatment on the spot. Rules differ by state and by age.
4. Search the price. Search oseltamivir on RxGator and compare pharmacies.
5. Ask about insurance and cash. Ask the pharmacist to compare your copay with the discount price.
6. Start the medicine right away. Finish the full course unless your prescriber tells you to stop.

Who Needs Treatment Most

The CDC advises prompt treatment for people who are hospitalized, people with severe or worsening illness, and people at higher risk of complications. Higher-risk groups include adults 65 and older, young children, pregnant people, and people with conditions such as asthma, diabetes, or heart disease.

The 48-hour window is a guide, not a hard cutoff. The CDC still recommends oseltamivir after 48 hours for hospitalized patients and for outpatients with complicated or worsening illness. If you are at higher risk, call even if you think that you are late.

Get emergency care for trouble breathing, chest pain, confusion, severe weakness, or symptoms that improve and then return.

Frequently Asked Questions

Does Medicare cover Tamiflu?

Most Part D plans cover generic oseltamivir, but your deductible may apply. Compare your plan price with the discount price. A discount card cannot be combined with Medicare, and that purchase usually does not count toward your deductible.

Do I need a flu test first?

Not always. The CDC says that treatment for high-risk patients should not wait for lab confirmation. Your prescriber decides.

Can antivirals prevent the flu after I am exposed?

Oseltamivir and baloxavir both carry approvals for prevention after exposure in certain people. Ask your prescriber promptly if someone in your home has the flu and you are at higher risk.

Do antibiotics treat the flu?

No. Antibiotics treat bacteria, and the flu is a virus. Your prescriber may use an antibiotic only if you develop a bacterial infection as well.

The Bottom Line

Generic oseltamivir remains the best value for most people, and the price gap between pharmacies is wide. Xofluza has a useful $50 cash offer, but the generic does not appear to be available. If flu symptoms start, call a prescriber the same day, then search your price on RxGator before you fill.
