Indications
Tapazole is a medication indicated to treat hyperthyroidism, or an overactive thyroid and Graves' disease. Tapazole contains an active ingriedent called Methimazole. Methimazole is an antithyroid drug that works by blocking the production of thyroid hormones. Its effectiveness comes from its ability to slow down the production of thyroid hormones, resulting in a decrease in symptoms like weight loss, heat intolerance, and high blood pressure.
Uses and Dosage
Tapazole is available in tablet form and should be taken orally by mouth with or without food as directed by a healthcare professional. To ensure the safe and effective use of Tapazole, take this medication exactly as directed by your doctor, usually 1 to 3 times a day. Do not increase your dose or take it more often than prescribed, as this can increase the risk of side effects without improving your condition any faster. Do not stop taking this medication without first consulting your doctor.
The recommended dose of Tapazole for adults ranges from 5 to 40 mg per day, taken orally by mouth, depending on the severity of hyperthyroidism. It is typically taken in 3 divided doses, spaced approximately 8 hours apart.
Your healthcare provider will monitor your thyroid hormone levels and adjust your dosage as needed to achieve optimal results. Once your thyroid hormone levels are stable, your doctor may recommend switching to a once-per-day dosage.
