ABSTRACT
INTRODUCTION: During pregnancy and breastfeeding, many women require prescription medications. Concerns about drug effects on the fetus or breastfed infant may lead to decreased adherence. Our objective was to evaluate the adherence of pregnant and breastfeeding Israeli women to prescription drugs, the information they received regarding drug safety, and the women's awareness and pattern of the use of Teratogen Information Services (TIS) in Israel. METHODS: We conducted a prospective observational cohort study among pregnant and breastfeeding women who had contacted the Israel Poison Information Center (IPIC) to consult about prescription medications. In a follow-up telephone call, we assessed adherence (defined as medication initiation by the time of the follow-up call) and the patients' recollection of the safety information given by the prescribing physician. In an additional cohort of post-partum women, we assessed their awareness about TIS in Israel. RESULTS: We included 59 pregnant women (62 prescriptions), 75 breastfeeding women (80 prescriptions), and 49 postpartum women. About two-thirds of all prescriptions were for antimicrobial drugs. By the time of the follow-up call, most participants (89% of pregnant and 89% of breastfeeding women) had initiated medications. Eight (11%) breastfeeding women stopped breastfeeding their babies while using the medication. Patients reported receiving explicit and unequivocal information concerning medication safety by the prescriber for 50% and 55% of prescriptions to pregnant and breastfeeding women, respectively. 70% of postpartum women interviewed in the maternity ward were not aware of TIS in Israel. DISCUSSION AND CONCLUSIONS: We observed high adherence rate to prescription medication therapy among pregnant and breastfeeding women in our cohort. Only about half of the women reported receiving comprehensive drug safety information by the prescriber. Raising awareness of the importance of medication safety counseling among both physicians and patients may contribute to the quality of medical care of pregnant and breastfeeding women in Israel.
