What is simeprevir?
Simeprevir is an antiviral medicine that prevents certain viruses from multiplying in your body. Simeprevir is used in combination with peginterferon alfa and ribavirin, or with sofosbuvir to treat hepatitis C genotype 1 or 4 in adults.
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. Every person with hepatitis C should remain under the care of a doctor.
Simeprevir may also be used for purposes not listed in this medication guide.
What is the most important information I should know about simeprevir?
Simeprevir is used in combination with other medications called peginterferon alfa and ribavirin.
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.
Do not use simeprevir with peginterferon alfa and ribavirin if you are pregnant, or if you are a man and your female sexual partner is pregnant. Ribavirin can cause birth defects or death in an unborn baby.
If you have ever had hepatitis B, simeprevir can cause this condition to come back or get worse. You will need frequent blood tests to check your liver function.
What should I discuss with my healthcare provider before taking simeprevir?
You should not use simeprevir if you are allergic to it.
Your doctor will perform blood tests to make sure simeprevir is the right treatment for your condition.
To make sure this medicine is safe for you, tell your doctor if you have:
a history of hepatitis B;
liver problems other than hepatitis, or if you have had a liver transplant;
kidney disease (or if you are on dialysis);
an allergy to sulfa drugs;
if you also take amiodarone (Cordarone, Pacerone);
if you are East Asian descent;
if you are receiving phototherapy (light therapy); or
if you have taken simeprevir, boceprevir (Victrelis), or telaprevir (Incivek) in the past and they were not effective.
Simeprevir 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 ribavirin if you are pregnant.
If you are a man, do not use ribavirin 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 at least 2 effective forms of birth control while either sexual partner is using ribavirin. Keep using 2 forms of 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 simeprevir with peginterferon alfa and ribavirin.
It is not known whether simeprevir passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
Simeprevir is not approved for use by anyone younger than 18 years old.

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. Every person with chronic hepatitis C should remain under the care of a doctor.
You should not stop using simeprevir suddenly. Stopping suddenly could make your condition harder to treat with hepatitis C antiviral medicine.
If you have ever had hepatitis B, simeprevir 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.
