Generic Name: sofosbuvir and velpatasvir (soe FOS bue vir and vel PAT as vir)
Brand Names: Epclusa
What is Epclusa?
Epclusa contains a combination of sofosbuvir and velpatasvir. Sofosbuvir and velpatasvir are antiviral medications that prevent hepatitis C virus (HCV) from multiplying in your body.
Epclusa is used to treat chronic hepatitis C in adults with HCV genotype 1, 2, 3, 4, 5, or 6.
Epclusa is sometimes used in combination with ribavirin. Ribavirin can cause birth defects or death in an unborn baby. Do not use ribavirin if you are pregnant, or if you are a man and your sexual partner is pregnant. Use effective birth control to prevent pregnancy while using these medicines together and for at least 6 months after treatment ends.
Read the medication guide or patient instructions provided with each medication in your combination therapy. Do not change your doses or medication schedule without your doctor's advice.
If you have ever had hepatitis B, Epclusa can cause this condition to come back or get worse. You will need frequent blood tests to check your liver function.
Before taking this medicine
You should not use Epclusa if you are allergic to sofosbuvir or velpatasvir.
To make sure Epclusa is safe for you, tell your doctor if you have:
a history of hepatitis B;
kidney disease (or if you are on dialysis);
liver problems other than hepatitis;
HIV (human immunodeficiency virus); or
if you have recently used a heart rhythm medicine called amiodarone (Cordarone, Pacerone).
It is not known whether Epclusa will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
Epclusa is sometimes used in combination with ribavirin. Ribavirin can cause birth defects or death in an unborn baby. You may need to have a negative pregnancy test before using these medications together, and every month during your treatment.
If you are a woman, do not use Epclusa with ribavirin if you are pregnant.
If you are a man, do not use this drug combination if your sexual partner is pregnant. An unborn baby could also be harmed if a man fathers the child while he is taking ribavirin.
Use effective birth control to prevent pregnancy while either sexual partner is using these medications together. Keep using this birth control for at least 6 months after treatment ends. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using Epclusa with ribavirin.
It is not known whether sofosbuvir and velpatasvir passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
How should I take Epclusa?
Epclusa is usually taken once per day for 12 weeks. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Your doctor will perform blood tests to make sure you do not have conditions that would prevent you from safely using this medicine.
You may take Epclusa with or without food.
You will need frequent blood tests to check your liver function.
Hepatitis C is often treated with a combination of drugs. Use all medications as directed by your doctor. Read all patient information, medication guides, and instruction sheets provided to you. Do not change your doses or medication schedule without your doctor's advice. Every person with chronic hepatitis C should remain under the care of a doctor.
You should not stop using Epclusa suddenly. Stopping suddenly could make your condition harder to treat with hepatitis C antiviral medicine.
If you have ever had hepatitis B, Epclusa can cause this condition to come back or get worse. You will need liver function tests during treatment and for several months after you stop using this medicine.
