This chapter has detail of the various mechanisms and effects of drugs on the thyroid gland. Iatrogenic thyroid disease is often due to overprescription of the antithyroid drugs such as carbimazole, methimazole, and propylthiouracil. Mechanism of action depends upon the effect of drugs which affects the thyroid function at various levels. Drugs affect thyroid-stimulating hormone, thyroid hormone secretion, TBG concentration etc. Various drugs interfere with the metabolic pathways of thyroid hormone and autoimmunity etc. The drug-induced effects described so far are mediated through the thyroid physiology. A reduction in absorption may necessitate an increase in thyroxine requirements and may decrease serum T4, while increasing serum TSH concentrations.
