Although this medication helps many people with hepatitis C, it may cause people who also have another liver problem called hepatitis B to get worse. Before starting this medication, tell your doctor if you have ever had hepatitis B. Tell your doctor right away if you have new or worsening symptoms of liver disease, such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, dark urine or yellowing eyes/skin.Show More
Sofosbuvir is used with other antiviral medications (such as ribavirin, peginterferon, daclatasvir) to treat chronic (long-lasting) hepatitis C, a viral infection of the liver. It works by reducing the amount of hepatitis C virus in your body, which may help your liver recover. Chronic hepatitis C infection can cause serious liver problems such as scarring (cirrhosis), or liver cancer.
Sofosbuvir in combination with other antiviral medications reduces the amount of hepatitis C virus in the body and helps the body's immune system fight the infection. It is not known if this treatment can prevent you from passing the virus to others. Do not share needles, and practice "safer sex" (including the use of latex condoms) to lower the risk of passing the virus to others.
Sofosbuvir must be used in combination treatment to have the best effect. Do not use sofosbuvir alone to treat hepatitis C.
