1. What ZEPATIER is and what it is used for

What ZEPATIER is

ZEPATIER is an antiviral medicine that contains the active substances elbasvir and grazoprevir.

What ZEPATIER is used for

ZEPATIER is used to treat long-term hepatitis C infection in adults aged 18 years and older.

How ZEPATIER works

Hepatitis C is a virus that infects the liver. The active substances in the medicine work together by blocking two different proteins that the hepatitis C virus needs to grow and reproduce. This allows the infection to be permanently removed from the body.

ZEPATIER is sometimes taken with another medicine, ribavirin.

It is very important that you also read the leaflets for the other medicines that you will be taking with ZEPATIER. If you have any questions about your medicines, please ask your doctor or pharmacist.

2. What you need to know before you take ZEPATIER

  • you have certain moderate or severe liver problems
  • you are taking any of the following medicines:
    • rifampicin, usually given for tuberculosis
    • HIV protease inhibitors such as atazanavir, darunavir, lopinavir, saquinavir, or tipranavir
    • efavirenz or etravirine for HIV
    • elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate or elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide for HIV
    • ciclosporin to stop organ transplant rejection or to treat serious inflammatory illnesses of eyes, kidney, joints or skin
    • bosentan for pulmonary arterial hypertension
    • carbamazepine or phenytoin, mainly used for epilepsy and seizures
    • modafinil to help people who cannot stay awake
    • St. John’s wort (Hypericum perforatum, a herbal medicine) for depression or other problems.

If you are taking ZEPATIER with ribavirin, please make sure that you read the "Do not take" section of the ribavirin package leaflet. If you are unsure of any information in the package leaflet, please contact your doctor or pharmacist.

Warnings and precautions

  • you have ever taken any medicine for hepatitis C
  • you have any liver problems other than hepatitis C
  • you have had a liver transplant
  • you have any other medical conditions.

Blood tests

Your doctor will test your blood before, during and after your treatment with ZEPATIER. This is so your doctor can:

  • decide if you should take ZEPATIER and for how long
  • decide what other medicines you should take with ZEPATIER and for how long
  • check for side effects
  • check if your treatment has worked and you are free of hepatitis C
  • check how your liver is working - tell your doctor straight away if you have any of the following signs of liver problems: loss of appetite; feeling or being sick; feeling tired or weak; yellowing of your skin or eyes; colour changes in your stool. Your doctor may want to test your blood to check how your liver is working if you develop any of these symptoms.

Children and adolescents

ZEPATIER is not for use in children and adolescents under 18 years of age. This is because ZEPATIER has not been tested in this age group.

  • rosuvastatin, atorvastatin, fluvastatin, simvastatin, or lovastatin, for lowering blood cholesterol
