Treatment-experienced with compensated cirrhosis: treat for 24 weeks; can be considered for 12 weeks with concomitant ribavirin (if eligible). Treatment-naïve and -experienced with decompensated cirrhosis (Child-Pugh B or C): treat for 12 weeks with ribavirin (see full labeling).

When co-administered with ribavirin, its contraindication also apply to this combination regimen (eg, Pregnancy Cat.X).

Warnings/Precautions:

Risk of HBV reactivation in patients coinfected with HCV/HBV. Test all patients for HBV infection by measuring HBsAg and anti-HBc; if positive serologic evidence, monitor for hepatitis flare or HBV reactivation during and at post-treatment follow-up; treat if clinically indicated. Increased risk of symptomatic bradycardia when concomitant amiodarone esp. patients also taking beta blockers or with cardiac comorbidities and/or advanced liver disease. Severe renal impairment (eGFR <30mL/min/1.73m²) or ESRD requiring hemodialysis. Decompensated cirrhosis. Pregnancy. Nursing mothers.

Interactions:

Concomitant certain immunosuppressants or chemotherapeutic agents: may increase risk of HBV reactivation. Concomitant amiodarone: not recommended; if no alternatives, monitor cardiac function (see full labeling). May increase absorption of concomitant P-gp and BCRP substrates. Concomitant P-gp inducers (eg, rifampin, St. John’s wort), other sofosbuvir-containing products, anticonvulsants (eg, carbamazepine, phenytoin, phenobarbital, oxcarbazepine), rifabutin, rifapentine, elvitegravir, cobicistat, emtricitabine, tenofovir DF, tipranavir/ritonavir, simeprevir, or rosuvastatin: not recommended. Separate dosing of antacids by 4hrs. May give H₂-antagonists simultaneously or 12hrs apart (comparable to max famotidine 40mg twice daily). May give PPI doses (comparable to omeprazole ≤20mg) simultaneously under fasted conditions. May potentiate digoxin, atorvastatin (myopathy); monitor. Concomitant tenofovir DF regimens without a HIV protease inhibitor/ritonavir or cobicistat; monitor. Concomitant atazanavir/ritonavir or cobicistat + emtricitabine/tenofovir DF, darunavir/ritonavir or cobicistat + emtricitabine/tenofovir DF, or lopinavir/ritonavir + emtricitabine/tenofovir DF: consider alternatives; or if coadmin necessary, monitor.
