Sofosbuvir Tablet

Description

Sofosbuvir and velpatasvir work directly against hepatitis C virus replication. The combination targets different proteins involved in the HCV life cycle, making it an important option in modern hepatitis C treatment.

The commonly used fixed-dose combination contains sofosbuvir 400mg and velpatasvir 100mg in one tablet.

What Is Sofosbuvir/Velpatasvir?

Sofosbuvir/velpatasvir is a combination of two direct-acting antiviral medicines:

• Sofosbuvir 400mg
• Velpatasvir 100mg

Sofosbuvir is an HCV nucleotide analogue inhibitor, while velpatasvir targets the HCV NS5A protein.

Together, these medicines interfere with different stages of hepatitis C viral replication.

The combination is commonly associated with the brand Epclusa, although generic versions may be manufactured by other pharmaceutical companies.

What Is Sofosbuvir Tablet Used For?

Sofosbuvir/velpatasvir is used for the treatment of chronic hepatitis C infection.

Depending on the patient’s clinical circumstances and applicable treatment guidelines, it may be used for HCV genotypes:

• Genotype 1
• Genotype 2
• Genotype 3
• Genotype 4
• Genotype 5
• Genotype 6

U.S. FDA information identifies sofosbuvir/velpatasvir for chronic HCV genotypes 1–6, with treatment considerations depending on cirrhosis and other clinical factors.

Australian regulatory information likewise identifies sofosbuvir/velpatasvir as a prescription medicine for chronic HCV, including genotypes 1–6.

How Does Sofosbuvir Work?

Sofosbuvir is a direct-acting antiviral that interferes with the HCV NS5B RNA-dependent RNA polymerase.

This enzyme is necessary for hepatitis C virus replication.

By inhibiting NS5B polymerase activity, sofosbuvir interferes with the virus’s ability to make new copies of its genetic material.

How Does Velpatasvir Work?

Velpatasvir targets the HCV NS5A protein, which plays an important role in viral RNA replication and the assembly of new virus particles.

By inhibiting NS5A, velpatasvir interferes with another essential stage of the hepatitis C virus life cycle.

The complementary activity of sofosbuvir and velpatasvir provides broad antiviral activity across multiple HCV genotypes.

Sofosbuvir/Velpatasvir Key Information

Always check the exact strength and formulation supplied with your product.

Sofosbuvir 400mg Tablet

Sofosbuvir 400mg is an important component of modern direct-acting antiviral treatment for hepatitis C.

When combined with velpatasvir 100mg, the fixed-dose tablet provides a once-daily antiviral combination used for chronic HCV infection.

Sofosbuvir should generally be used as part of a complete HCV treatment regimen rather than being taken independently without medical supervision.

Sofosbuvir Velpatasvir for Hepatitis C

Chronic hepatitis C can cause ongoing inflammation and damage to the liver. Over time, untreated infection may contribute to serious liver complications.

Modern HCV treatment uses direct-acting antivirals to directly target the hepatitis C virus.

Sofosbuvir/velpatasvir is one such combination and has activity against multiple HCV genotypes.

Treatment selection depends on factors including:

• HCV genotype
• Presence or absence of cirrhosis
• Previous HCV treatment
• Liver function
• Other medical conditions
• Other medicines being taken

How to Take Sofosbuvir/Velpatasvir

Take the medicine exactly as prescribed by your doctor or hepatitis specialist.

The commonly used sofosbuvir/velpatasvir tablet contains 400mg of sofosbuvir and 100mg of velpatasvir and is taken once daily, with or without food.

Important points:

• Take your tablet at approximately the same time every day.
• Swallow the tablet as directed.
• Do not skip doses unnecessarily.
• Do not stop treatment without consulting your healthcare professional.
• Do not change the treatment duration yourself.

The appropriate treatment duration depends on your clinical condition and the complete treatment regimen.

Sofosbuvir/Velpatasvir Dosage

The appropriate dosage and duration should be determined by a qualified healthcare professional.

For the commonly used fixed-dose combination, the tablet contains:

Sofosbuvir 400mg + Velpatasvir 100mg

Treatment duration can vary according to cirrhosis status, previous treatment history and the specific clinical situation.

Do not use an online dosage recommendation as a substitute for a physician’s HCV treatment plan.

Sofosbuvir Side Effects

Possible side effects associated with sofosbuvir/velpatasvir treatment can include:

• Headache
• Fatigue
• Nausea
• Diarrhea
• Insomnia
• Weakness

Some side effects may be related to other medicines used as part of the patient’s hepatitis C treatment regimen.

Contact your doctor if symptoms are severe, persistent or unusual.

Sofosbuvir/Velpatasvir Drug Interactions

Tell your doctor or pharmacist about all medicines, vitamins and herbal supplements you take.

Important interactions can occur with medicines that affect stomach acidity or alter the absorption or metabolism of velpatasvir.

Particular attention may be required with:

• Antacids
• H2-receptor antagonists
• Proton-pump inhibitors
• Certain anticonvulsants
• Rifampin
• Certain HIV medicines
• Amiodarone

Some medicines can significantly reduce antiviral concentrations and may make treatment less effective.

Never start, stop or change another medicine without consulting your healthcare professional.

Sofosbuvir/Velpatasvir and Amiodarone

A clinically important interaction can occur between sofosbuvir-containing regimens and amiodarone.

Serious slowing of the heart rate, including symptomatic bradycardia, has been reported with certain combinations.

Tell your doctor if you take amiodarone or have a heart rhythm condition before starting hepatitis C treatment.

Sofosbuvir and Hepatitis B

Patients being considered for direct-acting antiviral treatment for hepatitis C should be evaluated for hepatitis B virus (HBV) infection.

HBV reactivation has been reported in patients receiving HCV direct-acting antiviral therapy and can result in serious liver complications.

Your healthcare professional may perform appropriate blood tests before and during treatment.

Sofosbuvir/Velpatasvir and Pregnancy

If you are pregnant, planning to become pregnant or breastfeeding, consult your doctor before starting treatment.

Pregnancy considerations depend on the complete HCV treatment regimen and any additional medicines being used.

Do not start, stop or modify hepatitis C treatment without medical advice.
