Xofluza (baloxavir marboxil) is a prescription drug that’s used to treat and prevent the flu. Xofluza’s cost may depend on factors such as your dosage, whether you have health insurance, and the pharmacy you use.

Xofluza is prescribed for adults and some children to:

  • treat the flu when symptoms have lasted no more than 48 hours
  • prevent the flu after exposure to someone who has the flu

Xofluza is available in two forms that are both swallowed: a tablet and a liquid suspension (a type of liquid mixture).

The price you pay for Xofluza can vary. Your cost may depend on your treatment plan, your insurance coverage (if you have it), and the pharmacy you use.

To find out how much you’ll pay for Xofluza, talk with your doctor, pharmacist, or insurance provider.

Note: If you have insurance, you may need to get prior authorization before your insurance provider will cover Xofluza. This means your insurer and your doctor will discuss Xofluza in regard to your treatment. Then the insurance company will determine whether the drug is covered. If Xofluza requires prior authorization and you don’t receive it before you start treatment, you could pay the full cost of the drug.

Be sure to ask your insurance company whether Xofluza requires prior authorization.

How does the cost of Xofluza compare with the cost of Tamiflu?

Your cost for Xofluza or Tamiflu (oseltamivir) may depend on your health insurance coverage and which pharmacy you use.

Xofluza is only available as a brand-name drug. But Tamiflu is also available as the generic drug oseltamivir. Generics tend to cost less than brand-name drugs.

To find out how much you’ll pay for Xofluza, Tamiflu, or oseltamivir, talk with your insurance provider or pharmacist.

Xofluza only comes as a brand-name drug. It’s not currently available in a generic version. A generic contains an exact copy of the active drug in a brand-name medication but tends to cost less.

Why is there such a cost difference between brand-name drugs and generics?

Years of research and testing are needed to ensure that brand-name drugs are safe and effective. This testing can make the drugs expensive. The manufacturer of a brand-name drug can sell the drug for up to 20 years. After that, other drugmakers can create generic versions. This competition in the market can lead to lower costs for generics. And because generics have the same active ingredients as brand-name drugs, they don’t need to be studied again. This can also lead to lower generic costs.
