What is Sofosbuvir used for?

Sofosbuvir is used along with ribavirin (Copegus, Rebetol, Ribasphere, others) and sometimes another medication (peginterferon alfa [Pegasys]) to treat certain types of chronic hepatitis C (an ongoing viral infection that damages the liver) in adults.

What is the difference between Hep C genotypes?

The major HCV genotype worldwide is genotype 1, which accounts for 40%-80% of all isolates. Genotype 1 also may be associated with more severe liver disease and a higher risk of hepatocellular carcinoma. Genotypes 1a and 1b are prevalent in the United States, whereas in other countries, genotype 1a is less frequent.

What is HCV positive?

Negative – this means you were infected with hepatitis C virus, but the virus is no longer in your body because you were cured or cleared the virus naturally. Positive – this means you currently have the virus in your blood and are infectious, meaning you can spread the virus to others.

An acute HCV infection does not lead to a life-threatening disease and usually goes away after six months without any treatment.

What is the best treatment for hepatitis B?

Antiviral medications.

Several antiviral medications — including entecavir (Baraclude), tenofovir (Viread), lamivudine (Epivir), adefovir (Hepsera) and telbivudine (Tyzeka) — can help fight the virus and slow its ability to damage your liver.

Are all hep C genotypes curable?

Once-daily combination pills that can treat all genotypes of hepatitis C infection are curing almost everyone who completes a course of treatment, and drop-out rates during treatment are low, large ‘real-world’ cohort studies reported this week at The International Liver Congress in Vienna.

What blood test shows Hep C?

A blood test, called an HCV antibody test, is used to find out if someone has ever been infected with the hepatitis C virus. The HCV antibody test, sometimes called the anti-HCV test, looks for antibodies to the hepatitis C virus in blood.

Is HCV positive curable?

Today, chronic HCV is usually curable with oral medications taken every day for two to six months. Still, about half of people with HCV don’t know they’re infected, mainly because they have no symptoms, which can take decades to appear.

What are the four drugs used to treat HCV?

Here are the medications available to treat hepatitis C, plus some helpful information about what to expect during treatment.

Top medication types for Hepatitis C.
Ribavirin.
Direct-acting antivirals (DAAs)
Combination drugs.
Ledipasvir-sofosbuvir (Harvoni)
Elbasvir-grazoprevir (Zepatier)
Sofosbuvir-velpatasvir (Epclusa)

What class of drug is velpatasvir?

Velpatasvir is in a class of antiviral medications called HCV NS5A replication complex inhibitors. The combination of sofosbuvir and velpatasvir works by stopping the virus that causes hepatitis C from spreading inside the body.

Is sofosbuvir generic?

Even though Sovaldi (sofosbuvir) is brand name only on it’s own, it is actually available in generic antiviral combinations such as Epclusa and Harvoni.

Which HCV genotype is hardest to treat?

In the DAA era, HCV genotype 3 has emerged as the most difficult HCV genotype to treat. For treatment-naïve adults without cirrhosis, two regimens are recommended with equal evidence rating: (1) glecaprevir-pibrentasvir for 8 weeks, or (2) sofosbuvir-velpatasvir for 12 weeks.
