What is sofosbuvir, and what is it used for?
Sofosbuvir is an antiviral medicine used to treat certain types of hepatitis C virus (HCV) infection. It is used in combination with other HCV drugs, because combination therapy is what produces cure rates in most patients rather than sofosbuvir alone.
How does sofosbuvir work?
Sofosbuvir is a direct-acting antiviral (DAA) that targets an essential HCV enzyme involved in viral replication. By blocking this replication step, it reduces the amount of HCV in the body and allows other treatment components to eliminate the infection.
How is sofosbuvir typically taken?
Sofosbuvir is taken by mouth as part of an all-oral regimen (often with other DAAs). The exact drug combinations, dosing schedule, and treatment duration depend on factors such as the patient’s HCV genotype (or genotype status), prior treatment history, and the presence of liver disease.
What do people ask next: cure rates, timelines, and side effects?
Most modern HCV cure regimens built around sofosbuvir are designed as short courses (commonly measured in weeks), with the goal of achieving sustained virologic response (SVR), meaning the virus is no longer detectable after treatment.
Common questions from patients usually focus on:
- how quickly viral levels fall during treatment,
- what side effects can occur (which depend on the partner drugs in the regimen), and
- whether treatment is safe with existing medical conditions or other medications.
Is sofosbuvir still under patent, and where can I check?
