Sofab Tablet contains Sofosbuvir, an antiviral medication commonly used as a Sovaldi alternative for the treatment of chronic Hepatitis C virus (HCV) infection. It works by blocking the replication of the hepatitis C virus, helping reduce viral activity and supporting the body in controlling the infection more effectively. This medication is often prescribed as part of combination antiviral therapy for adults diagnosed with chronic hepatitis C. Sofosbuvir-based treatment may help improve liver health, reduce the risk of liver damage, and support long-term viral suppression when taken consistently under medical supervision.
