What Is Sovaldi?
Sovaldi (sofosbuvir) is an antiviral medication that prevents hepatitis C virus (HCV) from multiplying in your body. Sovaldi is used in combination with other medications to treat hepatitis C in adults. Sofosbuvir is sometimes used in people who also have HIV, or people who have liver cancer and are going to have a liver transplant. This medicine is not a treatment for HIV or AIDS.
Sovaldi must be given in combination with other antiviral medications and should not be used alone. Sovaldi is usually given with ribavirin (Copegus, Rebetol, Ribasphere, RibaTab) with or without peginterferon alfa (Pegasys, PegIntron).Sovaldi is also used together with Daklinza (daclatasvir) to treat hepatitis C genotype 1,2,3,4 infections in adults. Sovaldi is used in combination with other medications, usually ribavirin with or without peginterferon alfa.
