Adherence with prescription drugs in pregnant and breastfeeding women consulting with the Israel Poison Information Center Teratology Service.

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.
