What is sofosbuvir/velpatasvir used for?
Sofosbuvir/velpatasvir is an antiviral medicine used to treat chronic hepatitis C virus (HCV) infection. It’s taken as a fixed-dose combination (both drugs in one regimen), and it’s used in treatment plans determined by factors such as prior treatment history and the presence of cirrhosis.
How does sofosbuvir/velpatasvir work?
The combination pairs two direct-acting antivirals with different targets in the HCV life cycle:
- Sofosbuvir blocks viral RNA replication by inhibiting the HCV polymerase.
- Velpatasvir inhibits the HCV NS5A protein, which helps the virus replicate and assemble.
Using both drugs together helps increase the chance of achieving sustained virologic response (viral cure) compared with single-agent therapy.
What’s the dosing and treatment duration?
Dosing and length of therapy depend on the patient’s clinical situation (for example, cirrhosis status and whether the patient has had prior HCV treatment). Treatment regimens are typically described in the medicine’s prescribing information and follow HCV guideline pathways.
What side effects do patients ask about?
Common side effects reported with sofosbuvir/velpatasvir regimens can include fatigue and headache. Some patients also report nausea. The exact side-effect profile can vary based on what other medicines are used alongside it and a patient’s overall health.
Can people take sofosbuvir/velpatasvir with other drugs?
Drug interactions are a major consideration with this class. Patients should review all prescription drugs, over-the-counter medicines, and supplements with a clinician or pharmacist. Some interaction risks depend on acid-reducing medicines and certain enzyme-inducing drugs, which can change drug levels.

Are there alternatives?
Alternatives depend on the HCV genotype (though many modern regimens are pan-genotypic), prior treatment, and cirrhosis status. Clinicians choose among approved direct-acting antiviral combinations based on effectiveness and interaction profiles.
