Sovaldi (also known sofosbuvir) is a famous antiviral medicine that prevents hepatitis C virus (HCV) from reproducing in a human 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.But it`s important to mention that 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 3 infection in adults.
Sovaldi is used in combination with other medications, usually ribavirin with or without peginterferon alfa.
