What is Harvoni® (ledipasvir and sofosbuvir) used for?

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 genotypes 1, 4, 5, or 6. This medicine is for use in adults and children who are at least 12 years old or who weigh at least 77 pounds (35 kilograms).

Harvoni® is sometimes given in combination with another medicine called ribavirin.

How should I take Harvoni® (ledipasvir and sofosbuvir)?

Take Harvoni® exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Your doctor will perform blood tests to make sure you do not have conditions that would prevent you from safely using Harvoni®.

You may take Harvoni® with or without food. Take the medicine at the same time each day.

Harvoni® is usually taken once per day for 12 to 24 weeks. Follow your doctor’s dosing instructions very carefully.

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.
