You may already be infected with hepatitis B (a virus that infects the liver and may cause severe liver damage) but not have any symptoms of the disease. In this case, taking the combination of ledipasvir and sofosbuvir may increase the risk that your infection will become more serious or life-threatening and you will develop symptoms. Tell your doctor if you have or ever had a hepatitis B virus infection. Your doctor will order a blood test to see if you have or have ever had hepatitis B infection. Your doctor will also monitor you for signs of hepatitis B infection during and for several months after your treatment. If necessary, your doctor may give you medication to treat this infection before and during your treatment with the combination of ledipasvir and sofosbuvir. If you experience any of the following symptoms during or after your treatment, call your doctor immediately: excessive tiredness, yellowing of the skin or eyes, loss of appetite, nausea or vomiting, pale stools, stomach pain, or dark urine.
Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests before, during, and after your treatment to check your body's response to the combination of ledipasvir and sofosbuvir.
Talk to your doctor about the risk(s) of taking the combination of ledipasvir and sofosbuvir.

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.

The length of your treatment (8 to 24 weeks) depends on your condition, how well you respond to the medication, and whether you experience severe side effects.
