There are various medicines include molecular - targeted agent , cytokines , amiodarone , α - interferon , tincture of iodine , Li , anti - thyroidal drugs , a class of anti - cancer drug containing Sunitinib and others that trigger thyroid dysfunction or drug - induced thyroiditis or thyrotoxicosis by inhibiting thyroid gland hormone secretion and damage the thyroid glands . In drug - induced thyroiditis , thyroid gland becomes underactive in the main because of different response from sure medications which usually alter the binding of thyroid gland endocrine to globulin protein or the thyroid gland hormone metabolism and concentration .
Symptoms of Drug-Induced Thyroiditis

An echography of the thyroid gland by using sound wave reveals the occurrence of thyroiditis . A thyroid gland scan is also a undecomposed choice to find out the right functioning of thyroid gland gland . In this sheath , a dyestuff is injected before taking the picture and very rarely the patients may face an hypersensitised reaction to this injected dye . Fine phonograph needle biopsy is another subprogram involved in taking a sample distribution of the thyroid gland for examination of any mental defectiveness .

The dose is line up from prison term to clip in fiat to fetch down the TSH level to normal . Once the patient has startle thyroid gland alternate therapy , the patient may confront the symptoms of thyrotoxicosis or raised thyroid gland natural process which are advert in the following point :
Hyperthyroidism can be handle through play along procedures :
Drug - induced thyroiditis even causes pain in the area around the thyroid gland that can be often treated by non - steroidal anti - inflammatory drug or NSAIDs , even though corticosteroid medicinal drug may frequently be take . direction or treatment primarily imply only symptomatic relief either of pain sensation or softheartedness ; if it persists , then refurbishment of euthyroidism is needed .
