1. Why am I using Harvoni?

Harvoni contains the active ingredient ledipasvir and sofosbuvir. Harvoni is a direct acting antiviral. 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.

Harvoni is sometimes taken with another medicine, ribavirin.

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

Harvoni does not protect against re-infection with the HCV virus if cure has been achieved.

Harvoni is used to treat hepatitis C virus (HCV) infection in adults 18 years and older.

Hepatitis C is a virus that infects the liver.

2. What should I know before I use Harvoni?


Do not use Harvoni if:

  • you are allergic to ledipasvir, sofosbuvir or any of the ingredients listed at the end of this leaflet.
  • Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

  • Have liver problems, other than hepatitis C
  • Have a current or previous infection with the hepatitis B virus since your doctor may want to monitor you more closely.
  • Have kidney problems or if you are on haemodialysis.
  • Have diabetes
  • Have any other medical condition.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant. Harvoni may be used with ribavirin. Ribavirin can damage your unborn baby. It is therefore absolutely essential that you (and your partner) take all precautions not to get pregnant if you are taking ribavirin. You and your partner must use an effective birth control method during ribavirin treatment and during the 6 months after completing ribavirin treatment. It is very important that you read the Pregnancy section in the ribavirin product information very carefully.

Talk to your doctor if you are breastfeeding or intend to breastfeed. It is not known whether ledipasvir or sofosbuvir, the two active ingredients of Harvoni, pass into human breast milk.

Use in Children

Harvoni is recommended for adults. Harvoni has not been studied in children under 18 years of age.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

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
  • 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).
  • Warfarin or other similar medicines called vitamin K antagonists used to thin the blood.

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.

Get advice from a doctor or pharmacist if you take medicines used to treat stomach ulcers, heartburn or acid reflux. These medicines include:

  • 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 ledipsavir 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.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Harvoni.

4. How do I use Harvoni?

How much to take

  • The usual dose is one Harvoni tablet orally, once daily.
  • Harvoni tablets can be taken with or without food.
  • Follow the instructions provided and use Harvoni until your doctor tells you to stop.

When to take Harvoni

  • Harvoni should be taken at the same time each day to have the best effect. It will also help you remember when to take it.

If you forget to use Harvoni

Do not take a double dose to make up for the dose you missed. Continue with your regular dosing schedule.

Do not stop taking Harvoni unless your doctor tells you to. It is very important that you complete the full course of treatment to give the medicine the best chance to cure your hepatitis C virus infection.
