Safety and efficacy of DAAs for use in children younger than 18 years of age has been established with sofosbuvir (Sovaldi®), sofosbuvir/velpatasvir (Epclusa®), glecaprevir/pibrentasvir (Mavyret®), elbasvir/grazoprevir (Zepatier®), and ledipasvir/ sofosbuvir (Harvoni®)2-8, 10-11. Safety and effectiveness of sofosbuvir/velpatasvir/voxilaprevir (Vosevi®) has not been established in pediatric patients less than 18 years of age9. Recommended DAA dosages in pediatric patients are summarized in Table 3.
