boceprevir - peginterferon alfa-2b - ribavirin
How does this medication work? What will it do for me?
Boceprevir, peginterferon alfa-2b and ribavirin are three medications that work in combination to help the immune system fight the hepatitis C virus by making it harder for the virus to reproduce within the body. Boceprevir belongs to the class of medications known as protease inhibitors. Protease is an enzyme that viruses need for reproduction. Boceprevir blocks the action of protease, slowing the growth of the virus. Peginterferon alfa-2b belongs to the group of medications known as interferons. It works to help the body fight infections. Ribavirin belongs to the group of medications known as antivirals. It helps fight infection by interfering with the reproduction of the virus.
This combination medication is used to treat chronic (long-term) hepatitis C for people who have not been treated before, who have been treated with interferons and not responded well, and people with stable liver disease, including cirrhosis.
