Not recommended: It is not generally recommended that one become pregnant while on antithyroid drugs, since these drugs cross the placenta and can affect the baby. One would like to make sure that the overactive thyroid (usually graves disease) is in remission prior to attempting pregnancy. If you have radioactive iodine, one should wait 6 months before attempting pregnancy. Surgery will allow pregnancy soonest.
