Vosevi is a prescription medication specifically designed for the treatment of chronic hepatitis C virus (HCV) infection in adults. It is a combination antiviral medication that contains three active ingredients: sofosbuvir, velpatasvir, and voxilaprevir. This potent trio works together to inhibit the replication of the hepatitis C virus, thereby reducing the viral load in the body. Vosevi is particularly used in patients who have previously been treated with other HCV medications but did not achieve a sustained virologic response, making it a valuable option for those with limited treatment choices. It is administered in the form of a tablet, typically taken once daily, and is known for its high cure rates in various types of HCV, including patients with or without cirrhosis. Like all medications, Vosevi can cause side effects, so it's important for patients to be closely monitored by their healthcare provider throughout the treatment.
