What is Olysio?
Olysio (simeprevir) is an antiviral medicine that prevents certain viruses from multiplying in your body.
Olysio 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 Olysio and the other medications 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.
Olysio is used in combination with other medications. 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, simeprevir can cause this condition to come back or get worse. You will need frequent blood tests to check your liver function.
Call your doctor right away if you have symptoms of liver problems: vomiting, loss of appetite, feeling weak or tired, clay-colored stools, or jaundice (yellowing of the skin or eyes).
If you take simeprevir with sofosbuvir and amiodarone, call your doctor or get emergency medical help if you have: slow heartbeats, chest pain, extreme weakness, confusion, memory problems, and feeling light-headed or short of breath.
Avoid exposure to sunlight or tanning beds. Sunlight can cause a severe rash or skin reaction while you are using Olysio combination treatment. Use sunscreen and wear a hat, sunglasses, and protective clothing when you are outdoors.
Do not use Olysio 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.
Before taking this medicine
You should not use Olysio if you are allergic to simeprevir.
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 ever had:
liver problems other than hepatitis, or if you have had a liver transplant; or
if you are receiving phototherapy (light therapy).
Olysio 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 Olysio with 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.
Olysio 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.

What should I avoid while taking Olysio?
Avoid exposure to sunlight or tanning beds. Olysio combination treatment can make your skin more sensitive to sunlight, especially during the first 4 weeks of treatment. This may cause a severe sunburn or skin rash. Wear a hat, sunglasses, and protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
Avoid taking an herbal supplement containing St. John's wort at the same time you are taking simeprevir.
