Overview

Viekira Pak is a prescription medicine used to treat adults with chronic hepatitis C virus (HCV) infection, specifically genotype 1. It is a combination of four antiviral medicines: ombitasvir, paritaprevir, ritonavir, and dasabuvir. These medicines work together to stop the hepatitis C virus from multiplying in your body, helping to clear the infection. Viekira Pak is usually taken with or without ribavirin, depending on your specific type of hepatitis C and liver health. Treatment with Viekira Pak can lead to a cure for many people, meaning the virus is no longer detected in the blood after finishing therapy. It is important to take the medication exactly as prescribed and not to miss doses. Key points for patients: Viekira Pak does not prevent you from spreading hepatitis C to others, so continue to take precautions. Always inform your healthcare provider about all medicines you take, as Viekira Pak can interact with many other drugs.
