Complementary medicine use for psychiatric disorders in females of childbearing potential

Limited data suggest that the risk of patient or fetal harm is not increased if a patient becomes pregnant while taking omega-3 fatty acids or St John’s wort. The effectiveness of hormonal contraception is not reduced by taking omega-3 fatty acids. However, St John’s wort may reduce the blood concentration and effectiveness of some hormonal contraceptives—for further advice, see here.

If a patient taking omega-3 fatty acids or St John’s wort wishes to plan a pregnancy, see Principles of psychotropic use in females of childbearing potential for advice on preconception planning and Complementary medicine use for psychiatric disorders during pregnancy.
