A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

HARVONI (ledipasvir/sofosbuvir) is a medication prescribed to treat chronic hepatitis C (HCV) infection. It may be prescribed with or without the antiviral ribavirin. HARVONI generic is not available at this time.
Take 1 tablet (ledipasvir 90 mg/sofosbuvir 400 mg) by mouth once daily with or without food.
The length of treatment will depend on the genetic makeup of the hepatitis C virus causing the infection. The genetic type will also determine if HARVONI should be used in combination with ribavirin. Do not take HARVONI in a way different than prescribed by your doctor.
The recommended treatment regimens and durations include:
Your specific directions may be different than the regimens listed above based on the recommendation from your physician.
HARVONI is a combination of two different antiviral medications, ledipasvir, and sofosbuvir. Together, the drugs use two different pathways to stop the hepatitis C virus from copying itself.
The hepatitis C virus is made up of genetic material and a protective protein coat. The virus uses the protein NS5A to replicate its genetic material and create more virus particles. Ledipasvir inhibits NS5A, preventing viral replication.
Hepatitis C viruses also use the protein NS5B RNA-dependent RNA polymerase to replicate its genetic code. Sofosbuvir binds to this protein and stops it from functions.

Tell your doctor if you had ever tested positive for the hepatitis B virus. In people with both hepatitis B and hepatitis C infections, hepatitis B virus may reactivate, leading to hepatitis, liver failure, or death.
Tell your doctor if you are taking the heart rhythm drug amiodarone. People who take both medications may cause the heart to slow (bradycardia). Taking both medications at the same time is not recommended.
If you have diabetes, the treatment of hepatitis C may improve your blood glucose control. If you are taking medications for diabetes, they may cause hypoglycemia and need to be adjusted.
The most common adverse reactions when taking HARVONI include:
The side effects each person experiences will be different based on their disease and other medications they are taking for treatment.
