What is Tapazole used for?
Tapazole (methimazole) is used to treat a thyroid condition called hyperthyroidism in which the thyroid produces too much thyroid hormone. Tapazole may be used for purposes not listed on the packaging and is often used before thyroid surgery or radioactive iodine treatment.

Tapazole (methimazole) works by stopping the thyroid gland from making excess thyroid hormone. Methimazole prevents the natural interaction between iodine and peroxidase, thus reducing the production of the thyroid hormones T4 and T3.
