Uses

USES: This medication is used to treat chronic (long-lasting) hepatitis C, a viral infection of the liver. Ombitasvir, paritaprevir, and dasabuvir work by reducing the amount of hepatitis C virus in your body, which helps your immune system fight the infection and may help your liver recover. Ritonavir is used to increase ("boost") the levels of paritaprevir. This helps paritaprevir work better. This product may also be used with a certain other medication (ribavirin). Chronic hepatitis C infection can cause serious liver problems such as scarring (cirrhosis) or liver cancer. It is not known if this treatment can prevent you from passing the virus to others. Do not share needles, and practice "safer sex" (such as the use of latex condoms) to lower the risk of passing the virus to others.
