This medicine contains the active ingredient thiamazole, which is also known as antithyroid medicine. These medicines suppress the production of thyroid hormone. If there is high level of thyroid hormone in our body it can cause loss of weight, increased production of sweat, nervousness and diarrhea. Thiamazole is prescribed for the treatment of hyperthyroidism, also known as overactive thyroid, as well as for preparation for thyroid surgery to lower thyroid hormone levels.
