What is Mavyret?

Mavyret contains a combination of glecaprevir and pibrentasvir. Glecaprevir and pibrentasvir are antiviral medications that prevent hepatitis C virus (HCV) from multiplying in your body.

Mavyret is used to treat chronic hepatitis C in adults with HCV genotype 1, 2, 3, 4, 5, or 6.

Mavyret is sometimes given after other medicines have been tried without success.

Important Information

You should not use Mavyret if you have severe liver disease, or if you also take atazanavir or rifampin.

If you have ever had hepatitis B, Mavyret can cause this virus to come back or get worse. Your doctor will perform blood tests to make sure you do not have hepatitis B.

Before taking this medicine

You should not use Mavyret if you are allergic to glecaprevir or pibrentasvir, or if:

  • you have severe liver disease; or

  • you also take atazanavir or rifampin.

To make sure Mavyret is safe for you, tell your doctor if you have ever had:

  • hepatitis B;

  • liver problems other than hepatitis;

  • a liver or kidney transplant; or

  • HIV (human immunodeficiency virus).

It is not known whether Mavyret will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.

How should I take Mavyret?

Take Mavyret exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Your doctor will perform blood tests to make sure you do not have conditions that would prevent you from safely using Mavyret.

Mavyret is usually taken as 3 tablets once per day for 8 to 16 weeks.

Take with food.

You will need frequent blood tests to check your liver function.

You should not stop using Mavyret suddenly. Stopping suddenly could make your condition harder to treat with hepatitis C antiviral medicine.

Use all hepatitis C medications as directed and read all medication guides you receive. Do not change your dose or dosing schedule without your doctor's advice. Every person with hepatitis C should remain under the care of a doctor.

If you've ever had hepatitis B, using Mavyret can cause this virus to become active or get worse. You may need frequent liver function tests while using this medicine and for several months after you stop.

Store this medicine in the original container at room temperature away from moisture and heat. Keep each tablet in the foil blister pack until you are ready to take it.
