Amiodarone induced thyrotoxicosis (AIT) is a form of hyperthyroidism due to treatment with antiarrhythmic drug, amiodarone. Amiodarone induced thyroid dysfunction more commonly results in hypothyroidism, estimated to occur in 6-32% of patients, whereas hyperthyroidism from amiodarone use is estimated at 1-12%. [1]
Serious side effects include lung toxicity [7] such as interstitial pneumonitis, liver problems, heart arrhythmias, vision problems, thyroid problems, and death. [4] If taken during pregnancy or breastfeeding it can cause problems in the fetus or the infant. [4] It is a class III antiarrhythmic medication. [4]
Certain people make thyroid antibodies, and thyroiditis can be considered an autoimmune disease, because the body acts as if the thyroid gland is foreign tissue. [3] Some drugs, such as interferon, lithium, amiodarone (AIT type-2) and immune check point inhibitors can also cause thyroiditis. [4]
Levothyroxine is a frequently prescribed drug in the United States, particularly for older people, as lower thyroid function can be associated with aging. ... as side effects can cause problems.
Thyrotoxicosis factitia (alimentary thyrotoxicosis, exogenous thyrotoxicosis) [1] [2] is a condition of thyrotoxicosis caused by the ingestion [3] of exogenous thyroid hormone. [4] [5] It can be the result of mistaken ingestion of excess drugs, such as levothyroxine [6] and triiodothyronine, [7] or as a symptom of Munchausen syndrome.
The most common type of hyperthyroidism, Graves' disease, may additionally cause eye problems (Graves' ophthalmopathy) and skin changes of the legs (pretibial myxedema). [6] Thyroid disease may also cause muscle weakness in the form of thyrotoxic myopathy, but this is constant rather than episodic. [5]
The diagnosis of subacute thyroiditis can be made clinically by eliciting risk factors, associated symptoms, and physical examination. [1] [2] [3] Further work-up to differentiate between the etiologies of subacute thyroiditis can include: thyroid function tests (TFTs), inflammatory markers, complete blood count (CBC), and thyroid antibodies.
Amiodarone inhibits peripheral conversion of thyroxine to triiodothyronine; also interferes with thyroid hormone action. [citation needed] Lithium inhibits thyroid hormone release. [citation needed] Phenobarbitone, phenytoin, carbamazepine, rifampin induce metabolic degradation of triiodothyronine (T 3) and thyroxine (T 4). [citation needed]
