This product is currently out of stock and unavailable.

Antimicrobials are among the most commonly used drugs in pregnancy and lactation. They are prescribed for a variety of infections during or following pregnancy, including urinary tract infections, Group B streptococcal colonization, and mastitis. Antimicrobials present risks to the pregnant woman (some of which are unique to pregnancy), as well as risks to the unborn fetus or breastfed infant. When antimicrobials are prescribed for women using hormonal contraceptives, there is a potential for interactions that may result in undesired (or at least unexpected) pregnancy. As medication therapy experts, pharmacists can provide guidance to prescribers by conveying the complexities of pregnancy and lactation risk data, and provide guidance to patients by summarizing the data in an understandable manner. This issue will review considerations for safe use of antimicrobials in pregnancy and lactation, and discuss the known and potential effects of antimicrobials on hormonal contraceptive effectiveness. The principles of adverse drug effects in pregnancy and lactation are briefly reviewed, as well as the sources and limitations of data on the risks of antimicrobial use in these conditions. Tables 1 and 2 group commonly used oral antimicrobials into categories based on their risks in pregnancy and lactation, along with their current FDA pregnancy categories and Hale lactation risk ratings. Antiretrovirals to treat human immunodeficiency virus infection are not reviewed here, because they present a unique set of risk-benefit considerations. Following these sections is a discussion of mechanisms underlying the effects of antimicrobials on hormonal contraceptives; the table in the Patient Connection provides a summary of these interactions by drug and class.
