Use barrier methods of birth control (eg, condoms) if you have HCV infection. Talk with your doctor about safe sexual practices that protect your partner. Never share needles or other injection supplies. Do not share personal items that may have blood or body fluids on them, like toothbrushes or razors.

• Women who may become pregnant and men who use Boceprevir must use 2 effective forms of birth control while they take Boceprevir with ribavirin and for 6 months after treatment is stopped. Hormonal birth control (eg, birth control pills) may not be as effective while you are using Boceprevir. Talk with your doctor if you have questions about effective birth control.
