Herbal medicine use in parturients.

UNLABELLED: Alternative medicine use has increased dramatically over the last decade. Recently a 22% incidence of herbal medicine use in presurgical patients was reported. Of concern is the potential for these medications to cause adverse drug-herb interactions or other effects such as bleeding complications. We sought to determine the prevalence and pattern of use of herbal remedies in parturients. A one-page questionnaire examining the use of all prescription and nonprescription medications, including herbal remedies, was sent to parturients expected to deliver within 20 wk who had preregistered with the hospital's admissions office. Sixty-one percent of the parturients responded to the survey, with 7.1% of parturients reporting the use of herbal remedies. Only 14.6% of users considered them to be medications. Parturients in the 41--50 yr age bracket (5.6% of parturients) were the most likely to use herbal remedies (17.1% rate of use in this age group). Many parturients who took herbal remedies (46%) did so on the recommendation of their health care provider. IMPLICATIONS: Herbal medicine use may be less prevalent in the parturient population, however, some health care providers may be promoting their use during pregnancy.
