Use barrier methods of birth control (eg, condoms) if you have HBV 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. A vaccine is available to protect people at risk from becoming infected with HBV.
