Clinical Overview
Sofosbuvir Tablets (400mg) is a nucleotide analogue direct-acting antiviral on the WHO Model List of Essential Medicines.

Indicated in combination with other antiviral agents (daclatasvir, velpatasvir, or ribavirin) for the treatment of chronic hepatitis C across genotypes 1, 2, 3, 4, 5, and 6.
