Overview

What is Sofosbuvir?

Sofosbuvir (SOF) is a direct-acting antiviral (DAA) targeting the NS5B polymerase of the Hepatitis C virus. It is the backbone of most modern HCV treatment regimens, used in combination with other DAAs such as daclatasvir, ledipasvir, or velpatasvir. Treatment is typically 8–12 weeks with SVR12 (sustained virological response) rates exceeding 95% across all HCV genotypes.

Mechanism

How Does It Work?

Prodrug activation

Sofosbuvir is a prodrug that is converted intracellularly to its active uridine triphosphate analogue (GS-461203) by hepatic enzymes.

NS5B inhibition

GS-461203 acts as a chain terminator for the HCV NS5B RNA-dependent RNA polymerase, blocking viral RNA synthesis.

Pangenotypic activity

Sofosbuvir is active against all 6 major HCV genotypes with a high barrier to resistance, making it the universal backbone of HCV treatment.

Dosage

How to Use

Timing

Once daily, at the same time each day

How to Take

Frequency

Once daily

With Food

Take with food — reduces nausea and improves tolerability

Alcohol

FAQ

Frequently Asked Questions

Is Sofosbuvir the same as Sovaldi?

Sofosbuvir is the active ingredient in Sovaldi. A generic Sofosbuvir medicine contains the same active ingredient at the same strength and is taken the same way — the main difference is cost. Always use it as prescribed by a licensed medical professional.

What is the treatment success rate for Hepatitis C with Sofosbuvir?

Sofosbuvir-based regimens achieve SVR12 (sustained virological response) rates exceeding 95% for all HCV genotypes when taken as directed. Most patients require only 8–12 weeks of treatment.

Do I need to take Sofoxen 400 mg Tablets with other medicines?

Yes. Sofosbuvir is always used in combination with another direct-acting antiviral — typically daclatasvir, ledipasvir, or velpatasvir. Your doctor will choose the combination based on your HCV genotype and liver condition.

Can I take Sofoxen 400 mg Tablets if I have kidney disease?

Sofosbuvir requires an alternative if your eGFR is below 30 mL/min. Inform your doctor of your renal function before starting treatment.

What happens after I finish the Sofosbuvir course?

Your doctor will check your HCV viral load 12 weeks after completing treatment. An undetectable level at that point confirms SVR12 — the standard measure of treatment success for Hepatitis C.

⚠ BLACK BOX WARNING

Test all patients for current or prior HBV infection before initiating sofosbuvir-containing regimens. HBV reactivation has been reported and may result in fulminant hepatitis, hepatic failure, and death.

Drug Interactions

Drug / Substance	Effect	Action
