HARVONI is one tablet that contains two active substances, ledipasvir and sofosbuvir, which are given to treat hepatitis C virus infection in adults of 18 years and older.

Hepatitis C is a virus that infects the liver. This medicine works by lowering the amount of hepatitis C virus in your body and may lead to a cure of your HCV infection over a number of weeks.

Cure means the HCV virus is cleared from your blood (remains at an undetectable level) when measured 3 months after finishing all treatment.

HARVONI is for adults. HARVONI has not been studied in children under the age of 18.


Who should not take HARVONI

Together with your doctor, you need to decide whether HARVONI is right for you.

Do not take HARVONI if you are allergic to ledipasvir, sofosbuvir or any of the other ingredients of HARVONI. The ingredients of HARVONI are listed in the product description section of this leaflet.

Do not take HARVONI if you are taking any medicine other than HARVONI that contains sofosbuvir.

If you are pregnant think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. You should not breastfeed during treatment with HARVONI.

What should I tell my doctor before taking HARVONI

Tell your doctor if you:

Take any of the following medicines:

  • amiodarone used to treat heart conditions
  • digoxin used to treat heart conditions
  • rosuvastatin used to treat high cholesterol
  • tipranavir used to treat HIV infection
  • tenofovir disoproxil fumarate used to treat HIV infection

HARVONI may interact with these medicines. As a result, the amounts of HARVONI or other medicines in your blood may be affected. This may stop your medicines from working properly, or make any side effects worse. In some cases your doctor may need to give you a different medicine or adjust the dose of medicine you are taking.

Take any of the following medicines:

  • rifampicin, rifapentine, rifabutin (antibiotics used to treat infections, including tuberculosis);
  • St. John’s Wort (Hypericum perforatum - herbal medicine used to treat depression);
  • carbamazepine, phenytoin (medicines used to treat epilepsy and prevent seizures).

This is because they may make HARVONI work less well.

Take any medicines used to treat stomach ulcers, heartburn or acid reflux, such as:

  • antacids (e.g. aluminium hydroxide or magnesium hydroxide)
  • proton pump inhibitors (e.g. omeprazole)
  • H2-antagonists (e.g. famotidine).
    These medicines can decrease the amount of ledipasvir in your blood. If you are taking one of these medicines your doctor will either give you a different medicine for stomach ulcers, heartburn or acid reflux, or recommend how and when you take that medicine.

If you are taking an antacid, take it at least 4 hours before or at least 4 hours after HARVONI.

If you are taking a proton pump inhibitor, take it at the same time as HARVONI or up to 2 hours after taking HARVONI. Do not take before HARVONI.

If you are taking an H2-antagonist, your doctor may give you a different medicine or adjust the dose of the medicine you are taking.
