Tapazole is a thyroid medication used to treat hyperthyroidism, a condition where the thyroid gland is overactive. The medication is also used before thyroid surgery or radioactive iodine treatment to manage thyroid hormone levels.

Methimazole is a thionamide drug that reduces your levels of thyroid hormones such as triiodothyronine and thyroxine. By inhibiting the production of these hormones, Tapazole helps manage overactive thyroid glands.

This thyroid medication is an effective treatment of hyperthyroidism with a lower incidence of adverse effects compared to other forms of treatment such as propylthiouracil. Tapazole may also help decrease your risk of developing liver damage while increasing the thyroid-stimulating hormone to improve the management of your symptoms.

Uses and Dosage

The dose of Tapazole that is prescribed will vary depending on the individual being treated. Follow all your doctor’s instructions and read packaging labels carefully to ensure the best results during treatment.

  • Swallow tablets whole
  • Take a dose every 8 hours
  • Adults usually take an initial dose of 15mg for mild hyperthyroidism up to 60mg for severe hyperthyroidism, divided into 3 equal doses
  • Most adults take 5 to 15mg divided daily
