hyperthyroidism before pregnancy means through pregnancy there is antithyroid treatment on. Carbimazole crosses the placental barrier, hence can affect the development of thyroid gland in fetus causing hypothyroidism. So propylthiouracil is preferred as it does not cross the placental barrier. However, there are possible side effects of these drugs affecting the pregnancy. Usually antithyroid drugs are given for 12 to 18 months and stopped. That could be one option when hyperthyroidism is completely controlled.
