FDA pregnancy category X. Boceprevir is given together with interferon alfa and ribavirin. Although boceprevir is not expected to harm an unborn baby, ribavirin is known to 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. If you are a woman, you may need to have a negative pregnancy test before using these medications and every month during your treatment.

  • Use at least 2 non-hormonal forms of birth control while either sexual partner is using boceprevir with interferon alfa and ribavirin. Keep using 2 forms of birth control for at least 6 months after treatment ends.

  • Hormonal contraception (such as birth control pills, injections, implants, skin patches, and vaginal rings) may not be effective enough to prevent pregnancy during your treatment. Ask your doctor about using a non-hormone method of birth control (such as a condom, intrauterine device (IUD), diaphragm with spermicide) to prevent pregnancy while taking boceprevir.
  • Tell your doctor right away if a pregnancy occurs while either the mother or the father is using boceprevir with interferon alfa and ribavirin.
