If Harvoni has been prescribed for your child, please note that all the information in this leaflet is applicable to your child (in this case please read “your child” instead of “you”).
Harvoni granules are a medicine that contain the active substances ledipasvir and sofosbuvir which are given in a granule formulation. Harvoni is given to treat chronic (long-term) hepatitis C virus infection in adults and children 3 years of age and older.
Hepatitis C is a virus that infects the liver. The active substances in the medicine work together by blocking two different proteins that the virus needs to grow and reproduce itself, allowing the infection to be permanently eliminated from the body.
Harvoni 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 Harvoni. If you have any questions about your medicines, please ask your doctor or pharmacist.
If any of these conditions apply to you, do not take Harvoni and tell your doctor immediately.
Your doctor will know if any of the following conditions apply to you. These will be considered before treatment with Harvoni is started.

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 change with treatment of hepatitis C and therefore may affect other medications (e.g. medicines used to suppress your immune system, etc.). Your doctor may need to closely monitor these other medicines you are taking and make adjustments after starting Harvoni.
If you are not sure about taking any other medicines, talk to your doctor or pharmacist.
Some medicines should not be taken with Harvoni.
Taking Harvoni with any of these may stop your medicines from working properly, or make any side effects worse. Your doctor may need to give you a different medicine or adjust the dose of medicine you are taking.
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.
