The physiological actions of thyroid hormones are produced predominantly by T3, the majority of which (approximately 80%) is derived from T4 by deiodination in peripheral tissues. 10 Aluminum Lake, FD&C Yellow No. Thyroid hormones do not readily cross the placental barrier (see PRECAUTIONS - Pregnancy). Levothyroxine is in the FDA pregnancy category A. It is recommended that a physical examination and a serum TSH measurement be performed at least annually in patients receiving Synthroid (see WARNINGS, PRECAUTIONS, and DOSAGE AND ADMINISTRATION).

Oral cholecystographic agents and amiodarone are slowly excreted, producing more prolonged hypothyroidism than parenterally administered iodinated contrast agents. Levothyroxine is contraindicated in patients with uncorrected adrenal insufficiency since thyroid hormones may precipitate an acute adrenal crisis by increasing the metabolic clearance of glucocorticoids (see PRECAUTIONS).

Acenocoumarol Anisindione Chromium Colesevelam Conjugated Estrogens Dicumarol Eltrombopag Esterified Estrogens Estradiol Estriol Estrone Estropipate Imatinib Kelp Lanthanum Carbonate Lopinavir Phenindione Phenprocoumon Phenytoin Rifampin Rifapentine Ritonavir Sevelamer Simvastatin Sodium Polystyrene Sulfonate Soybean Warfarin Interactions with Food/Tobacco/Alcohol Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. These consequences include, among others, effects on growth and development, cardiovascular function, bone metabolism, reproductive function, cognitive function, emotional state, gastrointestinal function, and on glucose and lipid metabolism.
Thyrotropin-releasing hormone (TRH) released from the hypothalamus stimulates secretion of thyrotropin-stimulating hormone, TSH, from the anterior pituitary. The physiological actions of thyroid hormones are produced predominantly by T3, the majority of which (approximately 80%) is derived from T4 by deiodination in peripheral tissues.
