Choice of thionamide – The thionamide methimazole is the primary drug used to treat Graves' hyperthyroidism [1]. Methimazole is now almost exclusively used because of its longer duration of action, allowing for once-daily dosing, more rapid efficacy (figure 1), and lower incidence of side effects. Propylthiouracil (PTU) is preferred during the first trimester of pregnancy, because of the more significant teratogenic effects of methimazole, and in patients who have minor drug reactions to methimazole who want to avoid radioiodine or surgery.
