The effects of taking ursodeoxycholic acid tablets during late pregnancy are minor, but the effects on the fetus should be avoided as much as possible during the course of pregnancy and the drug needs to be used under the guidance of an obstetrician. Pregnancy is a special case of pregnancy that may cause biliary stasis and may result in discomfort of fullness in the right upper abdomen, or slight elevation of bilirubin and transaminases, which usually improves on its own after the pregnancy is lifted, i.e., after the fetus is delivered. If the symptoms are mild, no special treatment is needed. If the symptoms are typical or severe, biliary medications can be used under the guidance of an obstetrician. Cholestatic drugs, such as ursodeoxycholic acid or cholestrol capsules, usually have little effect on the pregnant woman or the fetus. However, the use of fetal medications needs to be very cautious and the medications should be used under the help and supervision of an obstetrician to avoid adverse effects on the pregnant woman and the fetus.
