In the management of hyperthyroidism during pregnancy, thyroid hormone replacement is not typically used. This treatment is generally employed to address hypothyroidism, where the body is not producing enough thyroid hormones. However, in the case of hyperthyroidism, the central issue is the overproduction of thyroid hormones. Administering thyroid hormone replacement would exacerbate the condition instead of alleviating it.

Beta blockers are often utilized in managing symptoms associated with hyperthyroidism, such as rapid heartbeat and anxiety. Propylthiouracil (PTU) is a common antithyroid medication used during pregnancy, especially during the first trimester, due to its lower risk compared to methimazole. Iodine solutions can also be used cautiously in certain situations, but they are generally avoided in early pregnancy because of potential effects on fetal thyroid development and function.

Thus, the choice of thyroid hormone replacement stands out as inappropriate in the context of hyperthyroidism, reinforcing the importance of tailored treatment approaches based on the specific thyroid-related condition being managed.
