What Viekira Pak is used for

Viekira Pak is used to treat chronic (lasting a long time) hepatitis C infection in adults including those with cirrhosis (scarring of the liver).

Hepatitis C is a liver disease caused by a virus which infects and damages liver cells.

This treatment consists of 2 different types of tablets.

These must be taken according to the instructions given by your doctor

Viekira Pak works by lowering the amount of hepatitis C virus in your body. It removes the virus from your blood over a period of time.

Ask your doctor or pharmacist if you have any questions about why it has been prescribed for you. Your doctor may have prescribed it for another purpose.
