To determine the rate of exposure of pregnant women to levothyroxine and to assess changes in these rates before, during and after pregnancy. 

Risk factors for discontinuation of thyroid hormone replacement therapy in early pregnancy: a study from the Norwegian Mother and Child Cohort Study and the Medical Birth Registry of Norway

This study aimed to identify the risk factors associated with discontinuation of thyroid hormone replacement therapy (THRT) in a population of women using THRT prior to pregnancy.

Maternal hypothyroidism in the perinatal period and childhood asthma in the offspring

There is increasing interest in the possible link between maternal hypothyroidism in the perinatal period and childhood asthma risk and whether the risk was moderated by thyroid hormone treatment during pregnancy.

The Increased Trend of Medical Treatment for Thyroid Diseases during Pregnancy: A 13-Year National Study

The study shows that the rate of levothyroxine use in pregnancy has markedly increased, which suggests that tracing and screening relevant patients and awareness of thyroid disorders on pregnancy and their significance for the pregnancy outcome have increased and the threshold to treat thyroid disorders has declined.

Thyroid hormone replacement therapy in pregnancy and motor function, communication skills, and behavior of preschool children: The Norwegian Mother, Father, and Child Cohort Study

The association between THRT during pregnancy and the first trimester and motor function, communication skills, and behavior in preschool children and these developmental outcomes are estimated.

Drugs in pregnancy

Department of Clinical Pharmacology, Copenhagen University Hospital Bispebjerg, the background risk of a child being born with a major congenital malformation is Institute of Clinical Medicine,



Prevalence of thyroid deficiency in pregnant women

Summary. objective The present study was designed to determine the current prevalence of gestational hypothyroidism, since maternal thyroxine deficiency is associated with poor obstetric outcomes and


The known effects of drugs on the developing fetus is discussed, a subject of great concern in the wake of the thalidomide tragedies of the late 1950s and early 1960s.

Thyroid testing and management of hypothyroidism during pregnancy: a population-based study.

The local guidelines are variable and poorly compliant with international guidelines, performance of thyroid testing is not optimal, and rates of elevated TSH at testing are extremely high in subgroups.

Management of thyroid dysfunction during pregnancy and postpartum: an Endocrine Society clinical practice guideline.

Practice guidelines are presented for diagnosis and treatment of patients with thyroid-related medical issues just before and during pregnancy and in the postpartum interval, including evidence-based approaches to assessing the cause of the condition, treating it, and managing hypothyroidism.

Subclinical Thyroid Disease and the Incidence of Hypertension in Pregnancy

Women with subclinical hypothyroidism identified during pregnancy have an increased risk for severe preeclampsia when compared with euthyroid women, and this is a secondary analysis of a prospective prenatal population-based study.

Subclinical Hypothyroidism and Pregnancy Outcomes

It is speculated that the previously reported reduction in intelligence quotient of offspring of women with subclinical hypothyroidism may be related to the effects of prematurity.

Low maternal free thyroxine concentrations during early pregnancy are associated with impaired psychomotor development in infancy

Maternal thyroid function during early pregnancy is an important determinant of early fetal brain development because the fetal thyroid is unable to produce any T4 before 12–14 weeks' gestation.

Postpartum thyroiditis.

The frequency of PPT varies between analyses and studies on risk factors do not establish reliable predictive models for progression of the disease, which underlines the need for early identification of risk groups aimed at prophylaxis and adequate treatment of thyroid dysfunction in the postpartum period.

Hypothyroidism Complicating Pregnancy

For comparison of the incidence and perinatal results, the experience with hypothyroidism at the Mercy Hospital for Women, Melbourne, for the 10 years, 1980–1989 is reviewed.
