What ZEPATIER is used for?

This medicine belongs to a group of medicines called direct-acting antivirals.

How ZEPATIER works

Hepatitis C is a virus that infects the liver. This medicine works by lowering the amount of Hepatitis C virus in your body. The active substances in ZEPATIER work together by blocking two different proteins that the hepatitis C virus needs to make more virus.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
This medicine is available only with a doctor’s prescription.
