Xofluza (baloxavir marboxil) is used to treat flu symptoms caused by influenza virus in people who have had symptoms for no more than 48 hours. It will not treat the common cold.
Xofluza is for adults and children who are at least 12 years old and weigh at least 88 pounds (40 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.
