at this time drugs are rarely tested for safety in pregnant women for fear of harming the unborn baby. until this changes pregnancy exposure registries help doctors and researchers learn how medicines affect pregnant mothers and their growing baby. a pregnancy exposure registry is a study that enrolls pregnant women who are using a certain medicine. the women sign up for the study while pregnant and are followed for a certain length of time after the baby is born. researchers compare babies with mothers who used the medicine while pregnant to babies with mothers who did not use the medicine. this type of study compares large groups of pregnant mothers and babies to look for medicine effects. a woman and her doctor can use registry results to make more informed choices about using medicine while pregnant. if you are pregnant and are using a medicine or were using one when you got pregnant check to see if there is a pregnancy exposure registry for that medicine. the food and drug administration has a list of pregnancy exposure registries (<link> that pregnant women can join.
in the future will there be better ways to know if medicines are safe to use during pregnancy?
