Tapazole Description

If you have been diagnosed with hyperthyroidism, your doctor may prescribe Tapazole or generic Methimazole. Hyperthyroidism causes your thyroid gland to produce excessive amounts of the hormone called thyroxine. The most common cause of hyperthyroidism is an autoimmune disorder known as Graves’ disease. This causes your immune system to attack your thyroid gland causing it to over-produce thyroxine. The generic alternative is not manufactured by the company that makes the brand product.

How Tapazole Acts in Your Body

Tapazole inhibits the production of the thyroxine hormone so your metabolism will slow down and eliminate the mood swings, sleep problems, fast heartbeat, and hand tremors. It can take weeks or months before this over-activity is reduced, so you must be patient and take Tapazole as directed.

Conditions Treated by Tapazole

The causes of hyperthyroidism are not completely known. However, it is assumed that hereditary and environmental factors influence the disease. There are several factors that indicate a person’s possible risk of getting Graves’ disease. These factors include genetics, gender, age, stress, pregnancy, and smoking. Because the over abundance of thyroid hormones in your body, you can experience weight loss, irritability, loss of body fat, and excessive sweating.

If Graves’ disease goes untreated physical signs may develop, such as enlargement of the thyroid gland known as goiter or thickening of the skin in the lower leg area. Eye problems associated with Graves’ disease can range from very mild to serious. Graves’ ophthalmopathy occurs when antibodies begin to attack the tissues behind your eyes and it causes a bug-eyed effect. Smoking is a major risk factor for thyroid eye disease!
