Treatment for Hyperthyroidism During Pregnancy —Reply

In Reply We agree that overt Graves disease hyperthyroidism requires treatment during pregnancy. As described in our review, risks for preeclampsia, low birth weight, miscarriage, and preterm delivery are increased without therapy, and as noted by Dr Watkins and colleagues, congenital anomaly risk is higher without treatment than when propylthiouracil is taken. For individuals who need treatment with antithyroid drugs during pregnancy, propylthiouracil is preferred over methimazole during the period of organogenesis.
