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.

In those with GT 1 and advanced cirrhosis (decompensated) or with GT 1 or 4 with or without cirrhosis (compensated) who have had a liver transplant, HARVONI is used with ribavirin.
Each 90 mg/400 mg tablet contains 90 mg ledipasvir and 400 mg sofosbuvir. The tablets include the following inactive ingredients: colloidal silicon dioxide, copovidone, croscarmellose sodium, lactose monohydrate, magnesium stearate, and microcrystalline cellulose
Hepatitis B virus reactivation: Before starting HARVONI treatment, your healthcare provider will do blood tests to check for hepatitis B infection. If you have ever had hepatitis B, the hepatitis B virus could become active again during and after treatment with HARVONI. This may cause serious liver problems, including liver failure and death. If you are at risk, your healthcare provider will monitor you during and after taking HARVONI.
