Exviera – Dasabuvir uses, dose, and side effects


250 mg film-coated tablets 

1. What Exviera is and what it is used for

Exviera contains the active substance dasabuvir. Exviera is an antiviral medicine used to treat adults with chronic (long-term) hepatitis C (an infectious disease that affects the liver, caused by the hepatitis C virus ).

Exviera works by stopping the hepatitis C virus from multiplying and infecting new cells, which eventually removes the virus from the blood.

Exviera tablets do not work alone. They are always taken together with other antiviral medicines containing ombitasvir/paritaprevir/ritonavir. Some patients may also need to take an antiviral medicine called ribavirin. Your doctor will tell you which of these medicines to take with Exviera.

It is very important that you also read the package leaflets for the other antiviral medicines that you are taking with Exviera. If you have any further questions on the use of this product, ask your doctor or pharmacist.

Pregnancy, breastfeeding, and fertility

  • Read the section on contraception in the package leaflet of ribavirin very carefully. Both men and women must read the information.
  • If you or your partner become pregnant during treatment with Exviera and ribavirin or in the months that follow, contact your doctor immediately.
