Introduction: Poorly treated or untreated maternal overt hyperthyroidism may affect pregnancy outcome. Fetal and neonatal hypo- or hyperthyroidism and neonatal central hypothyroidism may complete health issues during intrauterine and neonatal periods. Aim: To review articles related to appropriate management of hyperthyroidism during pregnancy and lactation. Methods: A literature review was performed using MEDINE with the terms "hyperthyroidism and pregnancy", "antithyroid drugs and pregnancy", "radioiodine and pregnancy", "hyperthyroidism and lactation", "antithyroid drugs and lactation", both separately and in conjunction with the terms "fetus", and "maternal". Results: Antithyroid drugs are the main therapy for maternal hyperthyroidism. Both methimazole (MMI) and propylthiouracil (PTU) may be used during pregnancy; however, PTU is preferred in the first trimester and should be replaced by MMI after this trimester. Choanal and esophageal atresia of fetus in MMI-treated and maternal hepatotoxicity in PTU-treated pregnancies are of utmost concern. Maintaining free T4 concentration in the upper one third of the normal range denotes success of therapy. Methimazole is the mainstay of the treatment of postpartum hyperthyroidism, in particular during lactation. Conclusion: Management of hyperthyroidism during pregnancy and lactation requires special considerations and should be carefully implemented to avoid any adverse effects on the mother, fetus and neonate.
