Mavyret (glecaprevir, pibrentasvir)

Mavyret® (glecaprevir, pibrentasvir) is a combination medicine used to treat hepatitis C virus (HCV). It is approved for use in children ages 3 and older and adults.1,2

Mavyret is used to treat people with:1,2

  • All 6 genotypes (strains) of HCV
  • Chronic HCV without cirrhosis
  • Chronic HCV with compensated cirrhosis
  • HCV genotype 1 infection who have been previously treated with either an NS5A inhibitor or an NS3/4A protease inhibitor, but not both

What are the ingredients in Mavyret?

The active ingredients in Mavyret are glecaprevir and pibrentasvir.1

How does Mavyret work?

The active ingredients in Mavyret work in different ways to attack the hepatitis C virus:1

  • Glecaprevir is an inhibitor of the protease HCV NS3/4A. HCV needs this enzyme to grow. Blocking this enzyme helps stop its growth.
  • Pibrentasvir inhibits HCV NS5A. This is a key protein HCV needs to multiply. Blocking this protein helps stop HCV growth.

Mavyret can reduce the HCV in the body to undetectable levels.1

What are the possible side effects of Mavyret?

The most common side effects of Mavyret include headache and fatigue.1

Mavyret has a boxed warning, the strictest warning from the U.S. Food and Drug Administration (FDA). This is because it may worsen or reactivate hepatitis B infection during or after treatment. This may cause serious liver damage, liver failure, or death. People with current or past hepatitis B infection should be monitored during and after treatment with Mavyret. Some may also need to be treated for hepatitis B. Before starting treatment with Mavyret, your doctor should check you for hepatitis B infection.1,2

These are not all the possible side effects of Mavyret. Talk to your doctor about what to expect or if you experience any changes that concern you during treatment with Mavyret.
