Xofluza

Generic name: Baloxavir Marboxil
Drug class: Miscellaneous antivirals

Usage of Xofluza

Xofluza is used to treat flu symptoms caused by the influenza virus in people who have had symptoms for no more than 48 hours. Baloxavir marboxil will not treat the common cold.

Xofluza is also used to prevent flu symptoms in people who have been in contact with someone who has the flu.

Xofluza is for adults and children at least 5 years old and weighing at least 44 pounds (20 kilograms).

Xofluza should not be used in place of getting a yearly flu shot. The Centers for Disease Control and Prevention recommends an annual flu shot to help protect you each year from new strains of influenza virus.

Before taking Xofluza

You should not use Xofluza if you are allergic to Baloxavir marboxil.

Tell your doctor if you are pregnant or plan to become pregnant. Having influenza during pregnancy can cause severe complications that could harm both mother and baby. The benefit of treating influenza may outweigh any risks to the baby.

The Centers for Disease Control and Prevention recommends that pregnant women get a flu shot during any trimester of pregnancy to protect themselves and their newborn babies from flu.

Tell your doctor if you are breastfeeding.
