What is the most important information I should know about boceprevir (Victrelis)?

Do not take boceprevir as your only medication to treat hepatitis C. Boceprevir must be used in combination with peginterferon alfa (Pegasys, PegIntron) and ribavirin (Copegus, Rebetol, Ribasphere, RibaTab).

Boceprevir is given together with interferon alfa and ribavirin. Ribavirin can cause birth defects or death in an unborn baby. Do not use this combination of drugs if you are pregnant, or if you are a man and your sexual partner is pregnant. Use at least 2 effective forms of birth control while either sexual partner is using interferon alfa and ribavirin. Keep using 2 forms of birth control for at least 6 months after treatment ends.

There are many other drugs that can interact with boceprevir. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor. Keep a list of all your medicines and show it to any healthcare provider who treats you.
