[Drug-induced thyroid dysfunctions].

latrogenic disorders are an important cause of morbidity, mortality, and admission to hospital in developed countries. Similarly to many other organs, the thyroid gland may be affected by various drugs, often used for the treatment of non-thyroid disorders. Drugs may affect thyroid function via different mechanisms, including thyroid hormone production, storage, secretion and metabolism offering numerous targets for drug interventions. Usually, the effect of pharmacotherapy is observed more frequently and is stronger in case of the presence of the concomitant disorder of this gland. An understanding of the proposed mechanisms of these drug interactions and their evaluation and differential diagnosis is helpful in the interpretation of the findings associated thyroid disorders and in establishing the correct treatment. The purpose of this article is to review the present state of knowledge on the influence of various drugs on the hypothalamic-pituitary-adrenal axis. We discuss pros and cons of the use of these agents in patients with concomitant thyroid disease and provide the reader with recommendations concerning the diagnosis and treatment of iatrogenic thyroid disorders.
