Documented Uses

• When used in combination with the antiviral medication [sofosbuvir], ledipasvir is indicated for the treatment of treatment of chronic hepatitis C virus (HCV) in adults and pediatric patients 3 years of age and older with the following conditions: - Genotype 1, 4, 5, or 6 infection without cirrhosis or with compensated cirrhosis. - Genotype 1 infection with decompensated cirrhosis, in combination with [ribavirin]. - Genotype 1 or 4 infection who are liver transplant recipients without cirrhosis or with compensated
• Breast Feeding; Lactation; Milk, Human; Antiviral Agents; NS5A Inhibitors
• Avoid St. John's Wort. This herb induces PGP and may reduce the serum concentration of ledipasvir.
• Take separate from antacids. Take at least 4 hours before or after antacids.
• Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.
• Established Pharmacologic Class [EPC] - Hepatitis C Virus NS5A Inhibitor
