Hepatitis B can be passed from a pregnant woman to a developing fetus. The good news is that there are good ways to prevent an infant at birth from developing chronic hepatitis B.

The infant should be vaccinated immediately upon birth with the first hepatitis B vaccine, and then complete the full vaccination series on schedule. In places in the world where HBIG is available, this extra injection further decreases the risk that the baby will develop chronic hepatitis B.

Taking medications for hepatitis B in pregnancy is a complex issue. There are always concerns about taking any medications in pregnancy. With hepatitis B there are specific circumstances that lead some women to elect hep B medications during pregnancy. This is best to discuss with a doctor who specializes in hep B in pregnancy as there are risks as well, and possibly long term ramifications. In general, hep B does not harm a pregnancy beyond the risk of passing the infection to baby. Again, this may be prevented with hep B vaccine and in some parts of the world, HBIG at birth.
