🔔 Why is this medication prescribed?

The combination of ledipasvir and sofosbuvir is used alone or in combination with ribavirin (Copegus, Rebetol, Ribasphere, others) to treat certain types of chronic hepatitis C (an ongoing viral infection that damages the liver) in adults and children 3 years of age and older. Sofosbuvir is in a class of antiviral medications called nucleotide polymerase inhibitors. It works by decreasing the amount of hepatitis C virus (HCV) in the body. Ledipasvir is in a class of antiviral medications called HCV NS5A inhibitors. It works by stopping the virus that causes hepatitis C from spreading inside the body.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Do not use if the seal over bottle opening is broken or missing. Store it at room temperature and away from light, excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily.
