Patient Population	Treatment Regimen and Duration
* In clinical trials in adults, regimens contained peginterferon alfa/ribavirin with or without an HCV NS3/4A protease inhibitor (boceprevir, simeprevir, or telaprevir). † See Dosage and Administration 2.3 and 2.4 for ribavirin dosage recommendations.

Recommended Dosage in Adults

The recommended dosage of EPCLUSA in adults is one tablet (400 mg sofosbuvir and 100 mg velpatasvir) taken orally once daily with or without food.

When administered with EPCLUSA, the recommended dosage of ribavirin is based on weight (administered with food): 1,000 mg per day for patients less than 75 kg and 1,200 mg for those weighing at least 75 kg, divided and administered twice daily. The starting dosage and on-treatment dosage of ribavirin can be decreased based on hemoglobin and creatinine clearance. For ribavirin dosage modifications refer to the ribavirin prescribing information.

Recommended Dosage in Pediatric Patients 3 Years of Age and Older

The recommended dosage of EPCLUSA in pediatric patients 3 years of age and older is based on weight and provided in Table 2. Table 3 provides the weight-based dosage of ribavirin when used in combination with EPCLUSA for pediatric patients. Take EPCLUSA oral pellets or tablets once daily with or without food. In pediatric patients less than 6 years of age, administer the oral pellets with food to increase tolerability related to palatability.

Preparation and Administration of Oral Pellets

See the EPCLUSA oral pellets full Instructions for Use for details on the preparation and administration of EPCLUSA oral pellets.

Do not chew EPCLUSA oral pellets to avoid a bitter aftertaste. EPCLUSA oral pellets can be taken directly in the mouth or with food (See Instructions for Use). In pediatric patients less than 6 years of age, administer the oral pellets with food to increase tolerability related to palatability. Sprinkle the oral pellets on one or more spoonfuls of non-acidic soft food at or below room temperature. Examples of non-acidic foods include pudding, chocolate syrup, and ice cream. Take EPCLUSA oral pellets within 15 minutes of gently mixing with food and swallow the entire contents without chewing.

Renal Impairment

No dosage adjustment of EPCLUSA is recommended in patients with any degree of renal impairment, including patients requiring dialysis. Administer EPCLUSA with or without ribavirin according to the recommendations in Table 1. Refer to ribavirin tablet prescribing information for ribavirin dosage modification for patients with CrCl less than or equal to 50 mL per minute.
