Brand Names: Harvoni
What is Harvoni?
Harvoni contains a combination of ledipasvir and sofosbuvir. Ledipasvir and sofosbuvir are antiviral medications that prevent hepatitis C virus (HCV) from multiplying in your body.
Harvoni is used to treat hepatitis C in adults.
Harvoni may also be used for purposes not listed in this medication guide.
You should not use Harvoni if you are also taking sofosbuvir tablets (Sovaldi).
If you have ever had hepatitis B, Harvoni can cause this condition to come back or get worse. You will need frequent blood tests to check your liver function.
Before taking this medicine
You should not use Harvoni if you are allergic to ledipasvir or sofosbuvir, or if you are also taking sofosbuvir tablets (Sovaldi).
To make sure Harvoni is safe for you, tell your doctor if you have:
a history of hepatitis B;
liver problems other than hepatitis;
kidney disease (or if you are on dialysis);
HIV or AIDS; or
a heart rhythm problem for which you take a medicine called amiodarone (Cordarone, Pacerone).
You should not use Harvoni with ribavirin if you have:
severe kidney disease;
a hemoglobin blood cell disorder such as sickle-cell anemia or thalassemia; or
if you are pregnant, or if you are a man and your sexual partner is pregnant.
Harvoni is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
Harvoni is sometimes used together with another medicine called ribavirin. Ribavirin can cause birth defects or death in an unborn baby. You may need to have a negative pregnancy test before taking ribavirin and every month during your treatment.
If you are a woman, do not take ribavirin if you are pregnant. If you are a man, do not take ribavirin if your sexual partner is pregnant. An unborn baby could also be harmed if a man fathers the child while he is taking ribavirin.
Use at least 2 effective forms of birth control to prevent pregnancy while either sexual partner is taking ribavirin. Keep using 2 forms of birth control for at least 6 months after treatment ends.
Tell your doctor right away if a pregnancy occurs while either the mother or the father is taking ribavirin.
It is not known whether ledipasvir and sofosbuvir passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Harvoni is not approved for use by anyone younger than 18 years old.

Hepatitis C is often treated with a combination of drugs. Use all medications as directed by your doctor. Read all patient information, medication guides, and instruction sheets provided to you. Do not change your doses or medication schedule without your doctor's advice. Every person with chronic hepatitis C should remain under the care of a doctor.
You should not stop using Harvoni suddenly. Stopping suddenly could make your condition harder to treat with hepatitis C antiviral medicine.
If you have ever had hepatitis B, ledipasvir and sofosbuvir can cause this condition to come back or get worse. You will need liver function tests during treatment and for several months after you stop using this medicine.
