What are the Risks of Antithyroid Medications in Pregnant Women?
While antithyroid medications are necessary to manage hyperthyroidism during pregnancy, they come with risks. Both methimazole and PTU can cross the placenta, potentially affecting fetal thyroid function. Methimazole has been associated with congenital anomalies such as aplasia cutis and choanal atresia. PTU, on the other hand, has been linked to potential liver toxicity. Therefore, the choice of medication and dosage must be carefully considered and regularly reviewed by healthcare providers.
