Mode of Action:

The combination of Sofosbuvir and Velpatasvir works synergistically to inhibit the replication of the Hepatitis C virus:

• Sofosbuvir is a nucleotide analog inhibitor of the NS5B RNA-dependent RNA polymerase enzyme, which is critical for viral RNA replication.
• Velpatasvir is an NS5A inhibitor that disrupts the assembly and replication of the virus. Together, they block the viral lifecycle at multiple stages, preventing the virus from multiplying and reducing the viral load in the body.

How to Use It:

Sofosbuvir and Velpatasvir combination tablets are taken orally, once daily, with or without food. The tablets should be swallowed whole without chewing, crushing, or breaking them.

Recommended Dosage:

• Standard Dosage: One tablet (Sofosbuvir 400 mg + Velpatasvir 100 mg) once daily for 12 weeks.
