What is Tapazole (Methimazole) prescribed for?

Hyperthyroidism is a condition when your thyroid makes too much of a hormone called thyroxine. Your thyroid controls things like how fast your heart beats and how quickly you burn calories. It releases hormones to control your metabolism. Hyperthyroidism, also known as overactive thyroid, can speed up your metabolism and cause unpleasant symptoms.

This medication treats your overactive thyroid, and it is put to work by stopping the thyroid gland from making too much thyroxin, which is a hormone created by your thyroid.
