EPCLUSA is a medication prescribed to treat chronic hepatitis C (HCV) infection. It can treat HCV genotypes 1, 2, 3, 4, 5, or 6. It can also be used to treat people with or without cirrhosis of the liver. There is no EPCLUSA generic available at this time. Hepatitis C is an infection of the liver caused by HCV. During hepatitis, the liver cells become inflamed and may be killed by the action of HCV. Hepatitis C can remain undetected for years with or without a person's knowledge. Once reactivated, it causes acute hepatitis C, which may become chronic or go away on its own. When a person has hepatitis C for a long period, they may develop cirrhosis, which is scarring on parts of the liver.

Epclusa (Sofosbuvir and Velpatasvir)

Take 1 tablet of EPCLUSA (velpatasvir 100 mg/sofosbuvir 400 mg) by mouth once daily with or without food. How long you take EPCLUSA and whether you take it in combination with other drugs will depend on whether or not you have cirrhosis and how severe it is. The recommended regimens and durations are: No cirrhosis or compensated cirrhosis (Child-Pugh A): EPCLUSA alone for 12 weeks, Decompensated cirrhosis (Child-Pugh B and C): EPCLUSA and ribavirin for 12 weeks Your regimen may vary from the above depending on factors that are specific to you. Do not take EPCLUSA differently than how your doctor or treatment team has prescribed it.
EPCLUSA contains a combination of the antiviral medications velpatasvir and sofosbuvir. They work via two different mechanisms that help to treat the infection more effectively. HCV is made up of viral genetic material and a protein coat. When HCV makes copies of itself, it must copy both the genetic material and the protein coat. NS5B is a protein that is important for replication of the viral genetic material, and velpatasvir binds to it, shutting it down. Sofosbuvir inhibits a protein critical to the replication of hepatitis C, NS5B RNA-dependent RNA polymerase. This enzyme helps to replicate the virus's genetic code, and by stopping this enzyme, sofosbuvir prevents the virus from replicating itself.

Tell your doctor if you have ever tested positive for the hepatitis B virus. In some people that are infected with both hepatitis C and hepatitis B, EPCLUSA may cause a dormant hepatitis B virus to re-activate. If this happens, it can cause fulminant hepatitis, liver failure, and death. EPCLUSA has an important drug interaction with the antiarrhythmic drug amiodarone. Tell your doctor or pharmacist if you are taking this medication. People who have taken both may experience a dangerous slowing of the heart called bradycardia.
The most common side effects of EPCLUSA may include: Anemia, Asthenia, Chills, Decreased appetite, Depression, Diarrhea, Fatigue, Fever, Flu-like symptoms, Headache, Increased kidney enzymes, Increased liver enzymes, Insomnia, Irritability, Myalgia, Nausea, Neutropenia, Pruritis, Skin rash Not everyone gets the same side effects of EPCLUSA.
