Treatment-experienced (genotype 1): treat for 16 weeks if previously treated with an NS5A inhibitor (without prior NS3/4A protease inhibitor) or for 12 weeks if previously treated with an NS3/4A protease inhibitor (without prior NS5A inhibitor); (genotypes 1, 2, 4, 5, 6): treat for 8 weeks (no cirrhosis) or 12 weeks (compensated cirrhosis) if previously treated with regimens containing PEG-IFN, ribavirin, and/or sofosbuvir, but no prior treatment with an HCV NS3/4A protease inhibitor or NS5A inhibitor; (genotype 3): treat for 16 weeks if previously treated with regimens containing PEG-IFN, ribavirin, and/or sofosbuvir, but no prior treatment with an HCV NS3/4A protease inhibitor or NS5A inhibitor. HCV/HIV-1 co-infected with or without compensated liver disease or renal impairment including on hemodialysis: follow same dosage regimen. Liver or kidney transplant: treat for 12 weeks; (genotype 1): treat for 16 weeks if NS5A inhibitor-experienced (without prior NS3/4A protease inhibitor); (genotype 3): treat for 16 weeks if prior treatment experience with regimens containing PEG-IFN, ribavirin, and/or sofosbuvir; see full labeling.

Mavyret Interactions


See Contraindications. Concomitant certain immunosuppressants or chemotherapeutic agents: may increase risk of HBV reactivation. May be antagonized by P-gp/CYP3A inducers (eg, carbamazepine, phenytoin, efavirenz, St. John's wort); concomitant use not recommended. May increase risk of ALT elevations with concomitant ethinyl estradiol-containing drugs (eg, combined oral contraceptives): not recommended. Concomitant darunavir, lopinavir, ritonavir: not recommended. Concomitant dabigatran etexilate; refer to its prescribing information for dose modification. Potentiates digoxin (reduce dose by ½); monitor. Concomitant use may potentiate atorvastatin, lovastatin, simvastatin: not recommended. May potentiate pravastatin (reduce dose by ½), rosuvastatin (limit max dose at 10mg), fluvastatin, or pitavastatin (use lowest effective dose of both these drugs). Patients requiring cyclosporine doses >100mg/day: not recommended. Monitor INR with warfarin, blood glucose in diabetics, or drug levels of concomitant CYP450 substrates with a narrow therapeutic index (eg, certain immunosuppressants).
