Drugs causing hypothyroidism
{"Image DocumentName": "Drugs causing hypothyroidism", "Image ImageDescription": "Methimazole/ Thiamazole: Block biosynthesis of thyroid hormones by inhibiting production of thyroid peroxidase. Propylthiouracl: In addition blocks peripheral conversion of T4-T3. Iodine: Deficiency and excess (inhibition of iodide organification and T4 and T3 synthesis esp. with underlying autoimmune disease) Lithium: interferes with release of thyroid hormones, causing transient elevation of TSH in a third and persistent hypothyroidism in 10% (esp. with underlying autoimmune disease) Amiodarone (iodine containing): inhibits thyroid hormone production and peripheral conversion (esp. with underlying autoimmune disease) 22% with overt or mild hypothyroidism in one study.
