You inform Sam that you recommend treatment with an anti-thyroid drug rather than radioactive iodine, as radioactive iodine may harm the baby. Dr. Raj agrees with your decision not to use radioactive iodine but she is a little concerned about your choice of anti-thyroid drug, in the first trimester of pregnancy, as methimazole has been associated with teratogenic effects in this setting. 

Please go back and re-consider.
