Sofosbuvir/Velpatasvir (Epclusa) (sofosbuvir and velpatasvir) — Uses, Dosage, Side Effects & Safety

Drug class: Infectious & Communicable Diseases

Overview

Sofosbuvir/Velpatasvir (Epclusa) is a combination antiviral medication used to treat chronic hepatitis C virus (HCV) infection in adults and children aged 3 years and older, regardless of HCV genotype. It is effective against all six major HCV genotypes, making it a pan-genotypic therapy. This medicine works by blocking two different proteins that the hepatitis C virus needs to multiply in the body. Sofosbuvir inhibits the NS5B RNA-dependent RNA polymerase, while velpatasvir inhibits the NS5A protein. By targeting these proteins, the medication helps stop the virus from replicating and allows the immune system to clear the infection. Key points for patients: Epclusa is usually taken once daily for 12 weeks, often with or without ribavirin depending on liver disease severity. It is important to take the medication exactly as prescribed and not to miss doses. Most people tolerate the treatment well, but regular monitoring by your healthcare provider is necessary.
