Mavyret (glecaprevir/pibrentasvir) is a prescription drug that works to treat hepatitis C infection. It does so by stopping the virus from copying itself. Your response to Mavyret may vary based on your medical history and diagnosis.

Mavyret is a combination of drugs in two classes, as follows:

  • glecaprevir: a hepatitis C virus (HCV) NS3/4A protease inhibitor
  • pibrentasvir: an HCV NS5A inhibitor

The way a drug works is known medically as its mechanism of action.

Mavyret works to cure hepatitis C in certain people by stopping, or inhibiting, the virus from copying itself. When specific blood tests no longer detect the virus, HCV is considered cured.
