For treatment-naïve patients with HCV 1a infection, the regimen is given with ribavirin (daily dose 1000 mg for those < 75 kg and 1200 mg for those ≥75 kg) for 12 weeks in patients without cirrhosis and for 24 weeks in patients with cirrhosis. For patients with subtype 1b infection, the regimen is given without ribavirin for 12 weeks, regardless of the presence of cirrhosis. This regimen is contraindicated in Child-Pugh classes B and C cirrhosis.
