HealthDay News — The combination drug Epclusa has been approved by the US Food and Drug Administration to treat the 6 major strains of chronic hepatitis C virus.

Epclusa combines sofosbuvir, FDA-approved in 2013, and the new drug velpatasvir. For patients with moderate-to-severe cirrhosis, Epclusa is approved to be used in combination with ribavirin. Epclusa also is approved for use in patients who haven’t developed cirrhosis, the agency said Tuesday in a news release.

Epclusa was evaluated in clinical trials involving 1,558 patients. Up to 99% of participants given the drug had no virus detected in the blood 12 weeks after treatment, the FDA said. The most common side effects reported were headache and fatigue. The drug’s label warns that Epclusa, when used with certain other drugs, including amiodarone, could lead to symptomatic bradycardia.

Epclusa is produced and marketed by Gilead Sciences, based in Foster City, Calif.
