A 32-year old woman with a past medical history of hyperthyroidism attends a GP appointment, as she has recently had a positive pregnancy test. She has never previously been pregnant. A urinary pregnancy test confirms the pregnancy, and she estimates she is likely around 8 weeks pregnant. The GP also organises some thyroid function tests, which show a low thyroid-stimulating hormone and an elevated level of free T4 of 48pmol/L (9-19). She is currently taking propranolol to manage her symptoms and has not taken any other anti-thyroid medications previously.
