Treatment of thyroid disease in pregnancy

Abstract

With appropriate therapy, complications related to thyroid disease in pregnancy can be minimized. Although the diagnosis of thyroid endocrinopathy may be difficult in pregnancy, few therapies are contra-indicated. Because medications may cross the placenta, however, clinicians need always to be mindful of potential fetal effects and should work to use the minimal dose necessary to achieve maternal euthyroidism. Thyroid function tests, in particular free T4 and TSH, remain good measures of thyroid function and therapy in pregnancy.
