Replacement therapy means the goal is a TSH in the normal range and is the usual therapy. Women with postpartum thyroiditis and subclinical hypothyroidism should be treated with levothyroxine to achieve a TSH level of less than 2.5 mIU per L if they are pregnant or desire fertility.15. Methods: In the case of postpartum, silent, or subacute thyroiditis, the radioactive iodine uptake during the hyperthyroid phase will be low. Although most women with postpartum thyroiditis will become euthyroid, treatment with levothyroxine should be considered in women with a serum TSH level greater than 10 mIU per L, or in women with a TSH level of 4 to 10 mIU per L who are symptomatic or desire fertility.
