1.What Victrelis is and what it is used for

What Victrelis is

Victrelis contains the active ingredient boceprevir which helps to fight against hepatitis C infection by stopping the virus multiplying. Victrelis must always be used together with two other medicines. These are called peginterferon alfa and ribavirin. Victrelis must not be used by itself.

What Victrelis is used for

Victrelis, in combination with peginterferon alfa and ribavirin, is used for chronic hepatitis C virus infection in adults (also called HCV infection).

Victrelis may be used in adults who are previously untreated for HCV infection or who have previously used medicines called ‘interferons’ and ‘pegylated interferons’.

How Victrelis works

Victrelis inhibits the direct replication of the virus and contributes in this way to lowering the amount of hepatitis C virus in your body.

2.What you need to know before you take Victrelis

Do not take Victrelis in combination with peginterferon alfa and ribavirin if you:

are allergic to boceprevir or any of the other ingredients of this medicine (listed in section 6)

are pregnant

have a condition called ‘autoimmune hepatitis’

are taking bepridil, pimozide, lurasidone, oral midazolam, oral triazolam, simvastatin, lovastatin, alfuzosin, silodosin, 'ergot’ type medicines (such as dihydro-ergotamine, ergonovine, ergotamine or methylergonovine), lumefantrine, halofantrine, quetiapine, or tyrosine kinase inhibitors.

Do not take Victrelis if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Victrelis.

Reminder: Please also read the “Do not use” section of the Package Leaflets for peginterferon alfa and ribavirin before you start taking Victrelis.

Warnings and precautions

have ever had a blood problem such as anaemia (when you lack enough healthy red blood cells, which transport oxygen around your body)

have ever had a blood problem such as neutropenia (lack of a certain type of white blood cells). Neutropenia affects the body's ability to fight off infections

have ever had a blood problem such as pancytopenia (a combination of low platelet, red and white blood cell counts)

have liver failure

have another liver problem in addition to hepatitis C infection

have HIV (human immunodeficiency virus) or have ever had any other problems with your immune system

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking Victrelis.

While taking the combination of Victrelis with ribavirin and peginterferon alpha, serious allergic reactions have been reported. Please see "Possible side effects" for more information.


Your doctor will have your blood tested regularly. These blood tests are done for a number of reasons:

so your doctor knows if the treatment is working for you

to help your doctor decide how long you will be treated with Victrelis.

to check for side effects.

Pregnancy and breast-feeding

Pregnancy must be avoided due to the use of Victrelis with ribavirin. Ribavirin can be very damaging to an unborn baby. Therefore, you and your partner must take special precautions in sexual activity if there is any chance for pregnancy to occur:

-if you are a woman of childbearing age who is taking ribavirin:

you must have a negative pregnancy test before treatment, each month during treatment, and for the 4 months after treatment is stopped. You must use an effective birth control during the time you are taking ribavirin and for 4 months after stopping treatment. This should be discussed with your doctor.

-if you are a man who is taking ribavirin:

do not have sex with a pregnant woman unless you use a condom. This will lessen the possibility for ribavirin to be left in the woman's body. If your female partner is not pregnant but is of childbearing age, she must be tested for pregnancy each month during treatment and for the 7 months after treatment has stopped. You or your partner must use an effective birth control during the time you are taking ribavirin and for 7 months after stopping treatment. This should be discussed with your doctor.

It is possible that boceprevir is excreted in human milk. If you are breastfeeding, your doctor will advise you to discontinue breastfeeding or to discontinue Victrelis while breastfeeding.

Reminder: Please also read the “Pregnancy and breast-feeding” section of the Package Leaflets for peginterferon alfa and ribavirin before you start taking Victrelis.

Driving and using machines

Victrelis does not affect your ability to drive or use tools or machines. However, the combination therapy of Victrelis, peginterferon alfa and ribavirin may make you feel tired, faint, a sensation of your head spinning, changes in blood pressure, confused or difficulty seeing clearly. If this happens, do not drive or use any tools or machines.

Victrelis contains lactose

Victrelis contains lactose (a type of sugar). If you have been told by your doctor that you cannot tolerate or digest some sugars (you have an intolerance to some sugars), such as Lapp lactase deficiency, or glucose-galactose malabsorption, talk to your doctor before taking this medicine.
