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

ZEPATIER is used to treat long-term hepatitis C infection in adults and children aged 12 years and older who weigh at least 30 kilograms.

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.

• you are allergic to elbasvir, grazoprevir or any of the other ingredients of this medicine (listed in section 6)
• 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.

Talk to your doctor or pharmacist before taking ZEPATIER if you:

• have a current or previous infection with the hepatitis B virus, since your doctor may want to monitor you more closely
• have ever taken any medicine for hepatitis C
• have any liver problems other than hepatitis C
• have had a liver transplant
• have diabetes. You may need closer monitoring of your blood glucose levels and/or adjustment of your diabetes medication after starting ZEPATIER. Some diabetic patients have experienced low sugar levels in the blood (hypoglycaemia) after starting treatment with medicines like ZEPATIER
• have any other medical conditions.

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.

ZEPATIER is not for use in children younger than 12 years of age.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes herbal medicines and medicines obtained without a prescription. Keep a list of your medicines and show it to your doctor and pharmacist when you get a new medicine.

There are some medicines you must not take with ZEPATIER. See list under “Do not take ZEPATIER if you are taking any of the following medicines.”

Tell your doctor or pharmacist if you take any of the following medicines:

• oral ketoconazole for fungal infections
• tacrolimus to prevent organ transplant rejection
• dabigatran to prevent blood clots
• rosuvastatin, atorvastatin, fluvastatin, simvastatin, or lovastatin, for lowering blood cholesterol
• sunitinib to treat certain cancers
• warfarin and other similar medicines called vitamin K antagonists used to thin the blood. Your doctor may need to increase the frequency of your blood tests to check how well your blood can clot.

Your liver function may improve with treatment of hepatitis C and therefore may affect other medications that are handled by the liver. Your doctor may need to closely monitor these other medicines you are taking and make adjustments during ZEPATIER therapy.

Your doctor may have to change your medicines or change the dose of your medicines.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking ZEPATIER.
