I have Graves’ disease and want to have a baby. What should I do before I try to become pregnant?

Talk to your doctor about how to prepare for pregnancy or about birth control if you do not want to become pregnant. If you take antithyroid drugs and want to get pregnant, ask your doctor about treatment with radioactive iodine (RAI). Women treated with RAI at least 6 months before pregnancy don’t need antithyroid drugs and can avoid exposing the unborn baby. If you have had RAI to treat Graves’ disease, you should wait at least 6 months before getting pregnant. Your doctor also will need to watch your baby for thyroid-related problems that can occur later in the pregnancy.
