What is Methimez® Antithyroid Methimazole USP?
The main benefit of Methimazole 5mg/10mg (Tapazole generic) is that it can be taken one, two, or three times a day (depending on your dosage). Pills are available in 5 or 10 milligrams. It also has fewer side effects and often reverses hyperthyroidism quickly. Methimazole is more concentrated than PTU. According to the American Thyroid Association clinical guidelines, the daily dosage varies from 10 to 40 milligrams, depending on the seriousness of your condition and your age. Again, this information is general, as dosing varies from patient to patient. Always follow your doctor’s specific dosing instructions.
Methimazole prevents the thyroid gland from producing too much thyroid hormone. Methimazole is used to treat hyperthyroidism (overactive thyroid). It is also used before thyroid surgery or radioactive iodine treatment. Methimazole may also be used for purposes not listed in this medication guide.
Side Effects of Antithyroid Medication Methimazole
Adverse reactions to antithyroid medications are uncommon (affecting only 1-3% of patients), but they do occur. These side effects include rash, itching, abnormal hair loss, and fever. Less common side effects include nausea, swelling, heartburn, muscle and joint aches, numbness, and headache.
In very rare instances, the drug can cause liver damage. In the most severe cases, this can result in death. Regular follow-up visits with your doctor will greatly reduce the risk of this severe complication.
