Viral infections:
Indications for: HARVONI
Chronic hepatitis C virus (HCV) infection in patients with: genotype 1, 4, 5, or 6 without cirrhosis or with compensated cirrhosis; genotype 1 with decompensated cirrhosis, in combination with ribavirin; or genotype 1 or 4 who are liver transplant recipients without cirrhosis or with compensated cirrhosis, in combination with ribavirin.
Adults and Children:
<3yrs: not established. Test for HBV infection prior to initiation. ≥3yrs (<17kg): 33.75mg/150mg (pellets) once daily; (17–<35kg): 45mg/200mg (tabs or pellets) once daily; (≥35kg): 90mg/400mg (tabs or pellets) once daily. ≥18yrs: 90mg/400mg (tabs) once daily. Genotype 1: Treatment-naïve without cirrhosis or with compensated cirrhosis (Child-Pugh A), or treatment-experienced without cirrhosis: treat for 12 weeks; treatment-naïve without cirrhosis who have pre-treatment HCV RNA <6 million IU/mL: can be considered for 8 weeks. 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). Genotype 1 or 4: Treatment-naïve and -experienced liver transplant recipients without cirrhosis or with compensated cirrhosis: treat for 12 weeks with ribavirin. Genotype 4, 5, 6: Treatment-naïve and -experienced without cirrhosis or with compensated cirrhosis: treat for 12 weeks. HCV/HIV-1 co-infection: follow same dosage schedule. See full labeling.
HARVONI Contraindications:
When co-administered with ribavirin, its contraindication also apply to this combination regimen (eg, Pregnancy Cat.X).
Boxed Warning:
Risk of HBV reactivation in patients coinfected with HCV and HBV.
HARVONI 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. Decompensated cirrhosis: monitor hepatic function. Pregnancy. Nursing mothers.

HARVONI Classification:
HCV NS5A inhibitor + HCV NS5B polymerase inhibitor.
HARVONI Interactions:
Concomitant amiodarone: not recommended; if no alternatives, monitor cardiac function (see full labeling). Concomitant P-gp inducers (eg, rifampin, St. John’s wort), other sofosbuvir-containing products, carbamazepine, phenytoin, phenobarbital, oxcarbazepine, rifabutin, rifapentine, elvitegravir, cobicistat, emtricitabine, tenofovir DF, tipranavir/ritonavir, simeprevir, or rosuvastatin: not recommended. Concomitant certain immunosuppressants or chemotherapeutic agents: may increase risk of HBV reactivation. May increase absorption of concomitant P-gp and BCRP substrates. 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. Monitor INR with warfarin.

Fatigue, headache, asthenia, nausea, diarrhea, insomnia.
